Answers key plz tnx

nasa pinaka last po yung answers

wala po bang answer key?

Answer key please

Answer to number 14 is B. 3,775

Using Gauss formula… the sum of 1 to n = n(n+1)/ 2

1 to 50 = 50(50+1)/2 = 1275 1 to 100 = 100(100+1)/2 = 5050 So, 5050 – 1275 = 3,775

May God bless you!!!!!

Ano po answer dun sa number 14 at number 21?

hey, ask ko lang po .. san ba mkikita mga part 2 neto ?

21 walang sagot error. binili nya ang candy sa halagang P90.25 then 35 lahat ng candy sa isang pack. tapos binenta nya ng tig P2.25 each so 35 * P2.25 = P78.75 P78.75 lang kita nya so wala siyang profit luge pa sya ng P11.25 kaya error. ang tanong kasi magkano profit nya.

P90.25 is the cost price but the retailers selling unit price is 2.25 which is lower than the cost unit price of 2.578.. Supposedly, to have profit selling unit price should exceed cost unit price to have gain. Thus, in #21 problem the question is about profit however there is no profit in that problem given its a loss on the side of the retailer.

Selling Price P78.75 Less: Cost Price ( 90.25) Profit/Loss (11.50)

panu po nakuha ung number 1? bakit po B ang answer? Thank you

First, you have to get each other's distance after 2 hours: North: d=st=30(2)=60 East: d=st=40(2)=80 Then, you have to apply Pythagorean Theorem in order to get the distance r^2 = a^2 + b^2 = 60^2 + 80^2 = 3600 + 6400=10 000 Get the square root of 10, 000 to get r= 100 km.

sa number 27 po, pano po nakuha? thank you

1 yard = 36 inches 1 yard^2 = 1296 inches^2 2 yard^2 = 2592 in^2

or, 2 yards = 72 inches (2 yards = 72 in)^2 4 yards^2 = 5184 in^2 2 yards^2 = 2592

Thanks for sharing . God bless po.

4. What value of x will satisfy the equation: 0.4(5x – 1470) = x? a. 490 b. 2,130 c. 1470 ang naka-indicate po na answer ay D. pero wla po sa choices x=588 tama po?

sa number 4 po ba ganito po ba process ng pag solve? distribution property, then transpose po. kasi po wala pong nakaindicate na choices D po. 0.4(5x-1470)=x 0.4(5x)-0.4(1470)=x 2x-588=x 2x=588 2x/2=588/2 x=294

588 po. di nyo na po na subtract ung isang x resulting to divide 588 by 2 which is wrong.

Hello po what is the right solution po sa # 4 ? salamat po sa maka ka sagot.

0.4(5x-1470)=x 0.4(5x)-0.4(1470)=x 2x-588=x (TRANSFER X AND -500 AND CHANGE SIGNS) 2X-X=588 X=588

#21. A retailer buys candies for P90.25. The pack has 35 pieces of candies. If she sells each candy for P2.25, how much profit does she make? 2.25*35=78.75 90-78.75=11.25

But suppose to be the price of each candy is more than 2.50 or 2.60 because 90.25/35=2.5785714 or 2.58

Pano po nakuha yung sagot sa no. 1? Solution please thanks

using Pythagorean theorem

solution po sa number 1?

8:00 pm they start to part ways, and the question is how many kilometers apart after 10:00 pm, so the one that traveling north with a rate of 30kph (kilometer per Hour)using that rate we multiply it by two because the difference of 8:00 and 10:00 is 2hours. so the distance of the bus that traveling north from the starting point is 60km. the same thing with the bus that travels east, multiply it and it obtain 80km far from the starting point. so not using an illustration you form a right angle. to get the distance of the two, use the pythagorean theorem (c^2 = a^2 +b^2)

Let a = distance of bus traveling north from the starting point which is 60km and b = distance of bus traveling east from the starting point which is 80km

c^2 = 60^2 + 80^2 then you'll obtain the distance of 100km

paano po basahin yun ^ na ito? anu po siya s math?

4^2 means 4²

mga sir at mam,

pa help na po s mga number na ito

number – 3,4, 5, 8, 10, 11, 12, 15, 16, 18, 21, 22, 23, 25, 26, 29, 30.

solution and answer po

At what rate per annum should P2400 be invested so that it will earn an interest of P800 in 8 years?ano po ba ang solution nito

800/8 years = 100 yearly interest To get its interest rate, 100/2,400 = 4.17%

9. At what rate per annum should P2400 be invested so that it will earn an interest of P800 in 8 years? a. 6 ½ % b. 5 ½ % c. 4.17 % d. 6 %

solution: principal(P) = 2,400 time (t) = 8 years interest = 800 rate (r) = ?

formula: I=Prt

800 = 2400(r) (8) 800 = 2400 (8) r 800 = 19200 r 800/19200 = r 0.041666 = r 0.041666 (100) = r

Answer : 4.17% =r

1. A 2h ×30km/h = 60km 2h ×40km/h = 80km 60+80 = 140 km at 10 pm

Paano po yung number 11. Na stuck ako e. Maraming salamat po sa sasagot!

Try mong gawing decimal ung my fraction…halimbawa dun sa dulo…20 3/4 gawin mong 20.75……3 devide 4 is 0.75….gawin mo rin dun sa iba makukuha mo na sagot

ano po ang answer Ng no.14 and 21

14. B 21. A

Ano po answer sa Number 4? :) salamat sa reply.

Pano po yung shortcut ngpagsolve sa number 14?

Ano po ung solution sa 2 ..

Mean Absolute Deviation (MAD) is simply calculating the positive distance (absolute value) of the mean from each data point and divided by the number of data points.

In No. 2 , the data points are 60, 80, 100, 75, & 95 The number of data points is 5. To get the mean, simple add all the data points and then divide by the number of data points. (Parang averaging lang) Mean = 60+80+100+75+95 = 410/5 = 82 Then the positive (absolute distance of the mean from each data points: | 60 – 82 | = 22 | 80 – 82 | = 2 | 100 – 82 | = 18 | 75 – 82 | = 7 | 95 – 82 | = 13

Then add all the distances and divide by the number of data points MAD = 22+2+18+7+13 = 62/5 = 12.40 Letter A

Ung easy way solution po ng mga deviation? Slamat po

Parang mali po ung answer sa number 19???

19. Ruben’s grades in 6 subjects are 88, 90, 97, 90, 91 and 86? What is the least grade that he should aim for in the 7th subject if he has to have an average of 88?

(88+90+97+90+91+86+x)/7 = 88 (542+x)/7 = 88 542+x=88*7 x=616-542 x=74

a. 92 b. 74 c. 88 d. 85

This comment has been removed by the author.

No. 17…Volume in cubic inches

Given: 1.5 feet by 1 1/2 feet by 3 inches

The formula of volume is side x side x side (or edge x edge x edge) Since the volume is to be in the form cubic inches, we need to convert all the measurement in inches: 1.5 feet = 1.5 x 12 inches = 18 inches 1 1/2 feet is the same as 1.5 feet = 18 inches 3 inches is already in inches Then just multiply the measurements = 18x18x 3 = 972 cubic inches

pwede nnyo e show youe solution lahay sa nakaka alam ng mga sagot. wala na po kasi akong idea pa help naman po

paano pa ung mean absolute deviation? sa no.2 po

60+80+100+75+95=410/5=82 60 of 82 = 22 80 of 82 = 2 100 of 82 = 18 75 of 82 = 7 95 of 82 = 13

22+2+18+7+13=62/5=12.4

Sa #14 anu po yung sagot? Thanks

Pano ung solution sa #6?

# 6 ==> 5 different counting numbers, the average is 100, what is possible highest number of one number? Trial and error po.

First determine the total of the 5 numbers. Since the average is 20, it suggests that the total of the 5 numbers is 100 ( because 100/5 = 20) If we try 90, the total of the remaining 4 numbers should equal 10 ( 100 – 90 = 10) Find 4 different numbers that totals 10 ==> 1, 2, 3, & 4 = 10 So the 90 is the highest possible number of one number in the group.

sir ano solution ng # 28&29?

solution Number 28 3T+2B=43 assuming no kids have trainng wheels on bicycles.

T+B=18 assume each bike and trike has only one kid on it.

3T+2(18-T)=43 T=43-36=7

Paano kinuha yung 24

First, you have to solve for the hypotenuse of both triangles. Let x be the hypotenuse of the smaller triangle y be the hypotenuse of the larger triangle by Pythagorean theorem: x=√[(9^2)+(12^2)] x=15

y=√[(12^2)+(16^2)] y=20

Then subtract the perimeter of the smaller triangle from the larger triangle (12+16+y)-(9+12+x) (12+16+20)-(9+12+15) 48-36 12

Pano po yung number 20? Nahihirapan na po kasi ako pag yung ratio talo talo na xD Salamat :D

add mo yung numbers sa ratio. 3+4+5 = 12 then gawin mong fraction yung number sa ratio. 3/12 : 4/12 : 5/12

cesar = 3/12 bert = 4/12 danny = 5/12 multiply mo na yung kay danny sa 24 para makuha yung hours ni danny. 5/12 * 24 = 10 then multiply 10 sa rate which is P50. P500 po yung sagot :)

anu po number yan?

Y number is letter d? Dva the average of the 5 numbers is 20?

can you show computations/solutions please thanks

Number 1. The answer is 140kph. Therefore: the answer is A.

Hi! I think you just added 60kph + 80kph, tama ba? That only works if the two vehicles left in OPPOSITE directions. :) For this problem, you need to find the HYPOTENUSE of the triangle formed by the two buses. The distance traveled by each bus represents the legs of the triangle. Applying the PYTHAGOREAN THEOREM, you get 100kph. That's basically just the square root of (60^2 + 80^2). ^_^

The answer in number 4 is 588. Please check this item. Thanks

Hello po sa # 4 hindi po ba ganito ang pag solve? 0.4(5x-1470)=x 0.4x5x=2x 0.4×1470=588 2×588=x 2x+x=3x 3x/3 =remove 588/3 =196 Tama po ba?

Hi how do you solve number 13? Thanks!

Ana = 1/5 of the job (3 hrs) Beth = x (3hrs) Ana and Beth = 1 job

1/5(3) + 3x = 1 3/5 + 3x = 1 3x = 1 – 3/5 3x = 2/5 x = 2/5 /3 x= 7.5

paano kinuha yung 7.5 nah sagut?? bakit x=2/5/3 bakit ang sagut is 7.5??? ano ang solution pls

1/5 = ana 1/n = beth 1/3 = both

1/5 + 1/n = 1/3 1/n = 1/3 – 1/5 1/n = 5/15 – 3/15 1/n = 2/15 2n = 15 n = 15/2 n = 7 1/2

pano po if unknown si ana? then 7.5 si beth? pano po?

solution of number 7 please. thanks

solution for number 7

5x + 4x + 1x = 62000 10x = 62000 10 10 x = 6200

5(6200) = 31000 4(6200) = 24800 1(6200) = 6200

31000-6200 = 24000

sa number 21 po anu sagot?

#21. A retailer buys candies for P90.25. The pack has 35 pieces of candies. If she sells each candy for P2.25, how much profit does she make? a. P11.50 b. P56.25 c. P37.50 d. P18.75

Profit = Sales – Cost of goods Profit = (35*2.25) – 90.25 Profit = 78.75 – 90.25 Profit = (-) 11.50

It is a negative profit..so it's a loss.

Hi po mga maam and sir ano po solution ng number18?

#18 is a ratio and proportion just take note of the total population which is 180. boys + girls = 180.

the ratio is (boys) / (boys+girls) = 5 / (5+7) 5/12 of the entire population are boys = 75.

(girls) / (boys+girls) = 7 / (5+7) 7/12 of the entire population are girls = 105.

pa check naman ng number 3 …thanks

how to download the reviewer from this?

paano po yung 25? tama po ba yung [(x1 + x2)/2, (y1 + y2)/2]? Thanks

iadd mo lang yung dalawang x values diveded by 2 para magkaroon ka ng x midpoint. same process sa y values para naman sa y midpoint

paano po yung solution sa number 9, i'm so confused po i really need help

yung item # 4, answer is D. Bakit po ganun, eh choices is up to C lang?

bakit po ganun yung 3? ^_^

How to solve item no.3 ?? plss

3. Which of the following is the factorization of the binomial x^2 – 4^2? a. (x + 4)(x + 2) b. (x – 4)^2 c. x(x + 2x + 2) d. (x – 4)(x + 4)

The binomial is in the form of (a^2 – b^2), a difference of two squares. Difference of two squares can be factored as (a+b) (a-b) Let a = x b = 4 So.. (a+b) (a-b) = (x+4) (x-4)

Ee diba po mafafactor mo pa yun 4 sa 2. Di po ba dapat (x-2)(x+2)?

in no. 21 why is it profit? suppose to be dba dapat lugi cya???

Wala po bang solutions?
