Answer:

4. $f,g\text{ and }h$ only.

Step-by-step explanation:

We have been given an expression $f+2g+\frac{h}{4}-7$ . We are asked to find the variables in the given expression.

We know that variable is a symbol or letter that represents an unknown value in a mathematical expression.

We can see that in our given expression $f,g\text{ and }h$ are unknown, therefore, these are variables for our given expression.

postnew [5]

Answer:

Mabel would have to draw a new angle that measured 97°.

Step-by-step explanation:

Supplementary angles always add up to 180°.

So, she would have to draw an angle that was $180$ ° $- 83$ °

Isabella uses the equation to find the volume of the cone below.

Rufina [12.5K]

Answer:

The correct answer option is: Isabella should have divided the product of $12\pi$ and 9 by 3 to get $V=\frac{12\pi (9)}{3}$

Step-by-step explanation:

We are given a diagram of a cone with height $9 cm$ and area of the base (circle) $12 \pi cm^ 2$ .

Isabella uses the equation $V = \frac { 1 } { 3 } ( 12 ) ^ 2 ( 9 ) \pi$ and we are to find the error that she is making in finding the volume of this cone.

The volume of a cone is given by: $\pi r^2\frac{h}{3}$ out of which $\pi r^2$ represents the area of the base (circle).

Therefore, Isabella should have divided the product of $12\pi$ and 9 by 3 to get $V=\frac{12\pi (9)}{3}$ .
