Answer:

50.24 meters

If you chose 50.24 meters and got it wrong, there is a mistake in the problem.

If the radius was 8, the answer would be c

Step-by-step explanation:

The diameter is 2r, therefore, 8 / 2 = 4.

pi multiplied by 4 squared would be 50.24

Joan has earned grades of 88, 94, 92, and 98 on math tests so far. What must her next grade be to give her an average grade of 6

Ira Lisetskai [31]

Answer:

see the explanation

Step-by-step explanation:

Let

x ------> the next grade

we know that

To find the average grade sum the grades by the number of math test

$60=\frac{(88+94+92+98+x)}{5}$

solve for x

Combine liker terms in the right side

$60=\frac{(372+x)}{5}$

Multiply by 5 both sides

$300=372+x$

Subtract 372 both sides

$300=372+x$

$x=-72$ -----> this is not make sense

The grade cannot be a negative number

For x=0

The minimum average grade is

$\frac{(372)}{5}=74.4$

Which direction does the graph of the equation shown below open? right, left, up, or down? x^2+6x-4y+5=0

Mademuasel [1]

X^2 + 6x - 4y + 5 = 0
4y = x^2 + 6x + 5
y = 1/4x^2 + 3/2x + 5/4

Since, x is the squred part and x^2 has a positive coefficient, therefore, the graph opens up.
