for example lets use 3^2 + 4^2, you add the main numbers, 3 and 4 to get 7, then there are still the exponents, the squared signs, they don't change, they stay as a two. If your problem required a single whole number, then you have to square the 7, 7*7 is 49, so that or 7^2 would be your final answer.
Answer:
2 and 7/8
Step-by-step explanation:
3 + 3/8 - 1/2
3 + 3/8 - 4/8
3 - 1/8
2 and 7/8
Answer:
<em>Correct choice: B</em>
Step-by-step explanation:
<u>Equation Solving</u>
The area of a trapezoid with height h and bases b1 and b2 is given by:
We must solve this formula for h.
First, multiply by 2 to eliminate denominators:
Now, divide by b1+b2:
Swapping sides:
Correct choice: B
Answer: -1 5/8 + 3 <em>or </em>-13/8 + 3
Step-by-step explanation:
1/2 (3/4x + 10) - 2 (x + 1)
3/8x + 5 - 2x - 2
Combine like terms
3/8x - 2x + 5 - 2
-1 5/8 + 3
or
-13/8 + 3
We know that 1 ft = 12 in.
The dimensions of the trunk of a car:
4 ft = 48 in wide, 3 ft = 36 in deep, 2 ft = 24 in tall.
V = 48 * 36 * 24 = 41,472 in³
41,472 in³ ≈ 4 * 10^4 in³
And the volume of the calculator:
V ( calc. ) = 3 * 4 * 12 = 144 in³
Answer:
Desi`s error is D ) The volume of the calculator is not about 60 in³.
