Answer:

12.76 in³

Step-by-step explanation:

The volume of a sphere formula is V = (4/3)πr³.

Here we use 3.14 for π and 1.45 in for r. We get:

V = (4/3)(3.14)(1.45 in)³ ≈ 12.76 in³

How do I do 21? (Will mark brainlest for explaining)

Maslowich

Let's say the number is x
75%of x is 15
75%x=15
0.75x=15
x=15/0.75
x=20

or you can say 3/4x=15
x=15*4/3
x=20

The product of a number and 9 less than the number is 90. Find the number.

Goryan [66]

Let's say this number is a:
a*(a-9) = 90
a^2-9a-90 = 0
(a-15)(a+6) = 0
a = 15 or a = -6
Therefor a. would be the correct answer :)

Joanna ran a mile in physical education class. After resting for one hour, her heart rate was 60 beats per minute. If her heart

umka2103 [35]

<span>Let x be Joanna's heart rate immediately after running one mile. After this heart rate x decreased by 2 over 5, Joanna's heart rate was 60 beats per minute. We can set up an equation to solve this question. x - (2/5) x = 60 (3/5) x = 60 x = (5/3) 60 x = 300 / 3 x = 100 Joanna's heart rate immediately after running one mile was 100 beats per minute.</span>

Select the inequality that corresponds to the figure:

vivado [14]

Answer:

C. 2x-y>-7

Step-by-step explanation:

The Line is not part of the region since is drawn in the graph using a dotted line, but we still need to find its equation.

The equation of a line is y=mx+b, where 'm' is the slope.

'm' can be obtained using the following formula.

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

To find the slope, as well 'b' we need points from the line, those will be (-6,-5), (0,7) as (x2,y2) and (x1,y1) respectively

Evaluating those point in the formula we have 'm' =2

Using now the above result and the point (0,7) in the equation y=mx+b, we obtain the value for 'b'.

7=2*0+b7

b=7

Hence our line is y=2x+7, and if we write it in standard form we obtain the following> y-2x=7.

Now, since our line is not part of the region, and the region is below that line, there is the < sign.

Hence the inequality that corresponds to the figure is y-2x<7 or, if we multiply by -1 (changin orientation of signs) 2x-y>-7
