Step-by-step explanation:
8-5 is 3 than multiply by 7 if shes out everyday
Answer:
1. 4
2. -4
3. -4
Step-by-step explanation:
Let's look carefully at each problem and explain it.
1. (-2)^2
This means find the square of the number -2. Since the square of a number means multiplying the number by itself, then
(-2)^2 means the product (-2) * (-2),
and since the product of two negative numbers is positive, then
(-2)^2 = (-2) * (-2) = 4
Answer is 4.
2. -2^2
Here, the exponent applies only to the 2, not to -2. This problem means square 2 and then take the opposite of the product. This can be written as
-(2^2)
-2^2 = -(2^2) = -(2 * 2) = -(4) = -4
Answer is -4.
3. -(2)^2
This is the same as problem 2 above. You square the 2 first, then take its negative.
-(2)^2 = -(2^2) = -(2 * 2) = -(4) = -4
Answer is -4
Answer:
4 sticks of clay
Step-by-step explanation:
To find the total amount of clay needed, multiply the number of students by the amount need for each one of them.
· ![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
Multiply these by converting 16 into a fraction.
· ![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
Multiply the numerators and denominators across.
· ![\frac{1}{4}=\frac{16}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D%3D%5Cfrac%7B16%7D%7B4%7D)
Simplify this.
![\frac{16}{4} =4](https://tex.z-dn.net/?f=%5Cfrac%7B16%7D%7B4%7D%20%3D4)
The total amount of clay needed is 4 sticks.
I hope this helps :) Good luck ^^
Let's call x the yards and "y" the meters. The equation that best relates the conversion from yards to meters knowing that a yard is 0.91 meters, will be given by x = (1 / 0.91) * y.
