Stephan curry of the golden state warriors made 29 baskets some were 2 points some were 3 points. If the total points he scores
seraphim [82]
<h2>Answer: He makes 261 baskets to earn 45 points.</h2>

Step-by-step explanation:

Since we have given that

Number of points = 2 + 3 = 5

Number of baskets = 29

if he makes 45 points,

We need to find the number of baskets.

According to question, we get that

\dfrac{5}{29}=\dfrac{45}{x}\\\\5x=45\times 29\\\\x=\dfrac{45\times 29}{5}\\\\x=261

Hence, he makes 261 baskets to earn 45 points.

What is the solution of the equation?<br><br> 35√(x+2)3+3=27
Arte-miy333 [17]

Use this rule: <em>(x^a)^b = x^ab</em>

3(x + 2)^3/5 + 2 = 27

Subtract 3 from both sides

3(x + 2)^3/5 = 27 - 3

Simplify 27 - 3 to 24

3(x + 2)^3/5 = 24

Divide both sides by 3

(x + 2)^3/5 = 24/3

Simplify 24/3 to 8

(x + 2)^3/5 = 8

Take the cube root of both sides

x + 2 = 3/5√8

Invert and multiply

x + 2 = 8^5/3

Calculate

x + 2 = 2^5

Simplify 2^5 to 32

x + 2 = 32

Subtract 2 from both sides

x = 32 - 2

Simplify 32 - 3 to 30

<u>x = 30</u>

I really need help, someone please help me
Hoochie [10]

Answer:

18.84 meters.

Step-by-step explanation:

The formula for a circle is πr^2.

πr^2 = 28.26

3.14 * r^2 = 28.26

r^2 = 9

r = plus or minus 3.

But since this deals with the area of a circle, there is no way a radius can be negative. So, the radius is 3 meters.

The formula for the circumference is 2πr.

2 * 3.14 * 3 = 6 * 3.14 = 18.84.

So, the circumference of the circle is 18.84 meters.

Hope this helps!

Find the location of the center of a circle if the endpoints of the diameter are at (-10,
Artyom0805 [142]

Answer:

(- 1, - \frac{1}{2} )

Step-by-step explanation:

The centre is located at the midpoint of the diameter.

Using the midpoint formula , then

centre = \frac{-10+8}{2}, \frac{-5+4}{2} ) = ( \frac{-2}{2}, \frac{-1}{2} ) = (- 1, - \frac{1}{2} )
