Answer:

60 serves

Step-by-step explanation:

Because a tennis player should be able to hit 2/5 of his or her first serves within the service line. In this case, Sam takes 150 serves so he must serve 2/5 of total servers during the match on the first serve, so he would serve within the service lines would be:

150 * 2/5

= 150*2 / 5

= 300 / 5

= 60 serves

Hope this helped :3

Please can anyone help me answer this question I'm really struggling with it

Anika [276]

Answer:

$v = {210cm}^{3}$

Step-by-step explanation:

Formula for finding the volume of a triangular prism is given as:

$v = \frac{1}{2} \times b \times h \times l$

where,

b = breadth = 7cm

h = height = 6cm

l = length = 10cm

Thus,

$v = \frac{1}{2} \times 7cm \times 6cm \times 10cm$

$v = \frac{1}{2} \times 420 {cm}^{3}$

$v = \frac{ {420cm}^{3} }{2}$

$v = {210cm}^{3}$

What are the real and complex solutions of the polynomial equation? X4-41x2=-400

stich3 [128]

For the answer to the question above, I'll provide a solution for my answer below.
x^4 - 41x^2 = - 400
=> x^4 - 41x^2 + 400 = 0 
=> x^2 = (1/2) [41 ±√(1681 - 100)] 
=> x^2 = (1/2) (41 ± 9) 
=> x^2 = 16 or 25

So, therefore, the answers for your problem are
=> x = ± 4 or ± 5.

I hope my answer helped you.

Find the area of the shaded region

AlexFokin [52]

Answer:

7 $\pi$ cm²

Step-by-step explanation:

First, find the area of the big circle with the formula A = $\pi$ r²

A = $\pi$ (3)²

A = 9 $\pi$

Now, we can find the areas of the smaller circles. Since they have the same radius, they are congruent (will have the same area)

A = $\pi$ r²

A = $\pi$ (1)²

A = $\pi$

Now, we will subtract the areas of the smaller circles from the area of the big circle to find the area of the shaded region:

9 $\pi$ - $\pi$ - $\pi$ = 7 $\pi$

So, the area of the shaded region is 7 $\pi$ cm²
