Answer:

-2

Step-by-step explanation:

5(2z + 4) = 0

Divide both sides by 5.

2z + 4 = 0

Subtract 4 from both sides.

2z = -4

Divide both sides by 2.

z = -2

Answer:

16 x 6 divided by 2 is 48

First add the two bases together whenever you're trying to find the area of a trapezoid then multiply it by the height and multiply by it by 1/2 (which basically you divide by 2).

The point slope form of the eqaution of the line that passes through (-5,-1) and (10, -7) is y+7= -2/5 (x - 10) what is the stan

stira [4]

Answer:

Step-by-step explanation:

The standard form of an equation of a line:

$Ax+By=C$

We have the equation in point-slope form:

$y+7=-\dfrac{2}{5}(x-10)$

Convert it to the standard form:

$y+7=-\dfrac{2}{5}(x-10)$ multiply both sides by 5

$5y+35=-2(x-10)$ use the distributive property a(b + c) = ab + ac

$5y+35=(-2)(x)+(-2)(-10)$

$5y+35=-2x+20$ subtract 35 from both sides

$5y=-2x-15$ add 2x to both sides

$2x+5y=-15$

A sphere has a radius of 7.5 centimeters. To the nearest cubic centimeter, what is the volume of the sphere?

Naya [18.7K]

Volume of sphere = 1766.25 cm^3

Step-by-step explanation:

The radius of sphere = 7.5 cm

Volume of sphere = ?

The formula used is:

$Volume= \frac{4}{3}\pi r^3$

Putting values:

$Volume= \frac{4}{3}\pi r^3\\Volume=\frac{4}{3}*3.14* (7.5)^3\\Volume= 1766.25\,\,\,cm^3$

So, Volume of sphere = 1766.25 cm^3

OLga [1]

She would by 3 packages of hot dogs and 2 packages of hot dog buns. This is because 3*8 would be 24 and 12*2 is also 24. These would both be the minimum amount of packages.
