<u>Answer</u>
12


<u>Explanation</u>
Cosine is the ratio of adjacent to hypotenuse.

So, in this case b is the adjacent and 13 is the hypotenuse.

cos22.6 = b/13
b = 13×cos22.6
    = 13×0.923879532
    =12.010

To the nearest whole number the answer is 12.

Given that
bonufazy [111]

Answer:

10.5 gallons

Step-by-step explanation:

48000 cm3 = 48 litres (1 litre = 1000 cm3)

Therefore if 1 litre = 1.75 pints then 48 litres = 48 x 1.75 = 84 pints.

Finally if 8 pints = 1 gallon

then 84 pints = (84 x 1) / 8 = 10.5 gallons

What number is 8% of 1,500?
Dima020 [189]

Answer:

120

Step-by-step explanation:

Solution for What is 8 percent of 1500:

8 percent *1500 =

(8:100)*1500 =

(8*1500):100 =

12000:100 = 120

Now we have: 8 percent of 1500 = 120

Question: What is 8 percent of 1500?

Percentage solution with steps:

Step 1: Our output value is 1500.

Step 2: We represent the unknown value with x.

Step 3: From step 1 above, 1500 = 100%

Step 4: Similarly, x = 8%

Step 5: This results in a pair of simple equations:

1500 = 100% (1).

x = 8% (2)

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

<u>1500</u>    =  <u>100%</u>

 x               8%

Step 7: Again, the reciprocal of both sides gives

<u>  x  </u>    =    <u>  8  </u>

1500        100

x = 120

Therefore, 8% of 1500 is 120

Hope this helps you!!!
