5o points and solve for the variable. (these are not answer choices solve them) 14.) 7/m = 16 to 2 15.) x to 18 = 14/4 16.) 30/20 = y to 7

14.  m = 7/8

15  x =63

16.  y= 21/2

Step-by-step explanation:

14.  7       16

    =

m           2

using cross products

7 * 2 = 16 * m

14 = 16m

divide by 16

14/16 = m

simplifiy

7/8 =m

14.  x       14

    =

    18         4

using cross products

4 * x = 18 * 14

4x = 252

divide by 4

4x/4 = 252/4

x = 63

15.  30       y

    =

    20         7

using cross products

30*7 = 20 y

210 = 20 y

divide by 20

210/20 =y

21/2 = y

14.  m = 7/8

15  x =63

16.  y= 21/2

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
