I always follow Order of Operations to solve these problems. Its
P - arentheses
E - xponents
M - ultiplication
D - ivision
A - ddition
S - ubtraction
So first you add (22+9) = 31 and then you multiply it by 6 that equals 186!
The answer is : 186!

Tom has 2 8-foot long boards he needs to cut pieces that are 15 inches long. How many 15 inch pieces can he cut from the two boa

Ksju [112]

Answer:

Tom can cut 12 (15 inch pieces) from the two boards.

Step-by-step explanation:

We're first given foot measurements and we're asked to find the answer in inches. That means we must convert 8 feet to inches, which is a 1:12 inches conversion. 8 times 12 will give you 96, so now you will multiply that value by 2 because Tom has 2 8-foot long boards. That will give you 192 inches. Since the question is asking for 'how many 15 inch pieces he can cut from the two boards?', you will need to divide 192 inches by 15 to find the answer. This will give you 12.8 boards. Because you can't have parts of an object, the answer will be 12 whole boards.

Quarters. 34×0.25= 8.50
dimes. 13×0.10= 1.30
Nickels. 4×0.05= 0.20

12 less than the quotient of a number and seven is -2 find the number

kiruha [24]

A quotient is the result of a division.
Let the unknown number be x.

We translate the problem into an equation, piece by piece.

"quotient of a number and seven" ----> x/7

"12 less than the quotient of a number and seven" ----> x/7 - 12

The word "is" means "="
x/7 - 12 =

All the above is -2, so it equals -2.

x/7 - 12 = -2

$\dfrac{x}{7} - 12 = -2$

First, add 12 to both sides and simplify.

 $\dfrac{x}{7} - 12 + 12 = -2 + 12$


 $\dfrac{x}{7} = 10$ 

Next, multiply both sides by 7.

$\dfrac{x}{7} \times 7 = 10 \times 7$

$x = 70$

Answer: The number is 70.

A sporting goods company used 904.39 cubic inches of air to inflate a red rubber ball. What is the radius of the ball

Charra [1.4K]

Answer:6.0002inch

Step-by-step explanation:

Volume of sphere=904.39

π=3.14

Volume of sphere=4/3 xπ x r^3

904.39=4/3 x 3.14 x r^3

904.39=(4x3.14xr^3) ➗ 3

904.39=(12.56xr^3) ➗ 3

Cross multiplying we get

904.39x3=12.56xr^3

2713.17=12.56xr^3

r^3=2713.17 ➗ 12.56

r^3=216.02

Taking the cube root of both sides

r=3√216.02

r=6.0002
