Answer:

C. An Exponent

Step-by-step explanation:

It is C because the number being squared is called the base number. In this case the base number is x.

The exponent, the amount of times that the base number will be multiplying itself by is 2.

Therefore, in x^2, the 2 is the exponent.

Triangle ABC has angle measures as shown.

sladkih [1.3K]

As with any triangle, the sum of angles is 180°.

(a)
(x -5) +(3x +30) +35 = 180 . . . . . sum of angles is 180
4x +60 = 180 . . . . . . . . . . . . . . . . collect terms
4x = 120 . . . . . . . . . . . . . . . . . . . . subtract 60
x = 30 . . . . . . . . . . . . . . . . . . . . . . divide by 4

(b)
Angle A = x -5 = 30 -5 = 25

Angle B = 3x +30 = 3*30 +30 = 120

A regulation basketball has a diameter of about 9 in. What is the best approximation for the volume of this ball? 3050 in³ 382 i

Mandarinka [93]

The best apporximation for the volume of this ball is 382 cubic inches.

<h3>What is the volume of the ball?</h3>

The volume of the ball is calculated by the formula V = 4 / 3πr³. This formula is the same in the whole world.

Given

A regulation basketball has a diameter of about 9 in.

The radius of the ball is;

$\rm Radius = \dfrac{Diameter}{2}\\\\Radius=\dfrac{9}{2}\\\\Radius=4.5\ inches$

The volume of the ball is;

$\rm Volume =\dfrac{4}{3}\pi r^3\\\\Volume=\dfrac{4}{3} \times 3.14 \times 4.5^3\\\\Volume =\dfrac{144.53}{3}\\\\Volume = 381.51\\\\Volume = 382 \ In^3 \ apporx$

Hence, the best apporximation for the volume of this ball is 382 cubic inches.

What is the equation in standard form of the line y=1/9x + 5

Maurinko [17]

<h2><em>The standard form for the equation of a line is Ax+By=C In this case with the equation y=1/9x+5 B=1 and A=1/9 and C=5 in order to get Ax and By on the same side we can subtract 1/9x from both sides to get this in the correct form and we get </em><u><em>Y-1/9x=5</em></u><em> </em></h2><h2 />
