Step-by-step explanation:

-81= -45-9n

+45 +45

-36= -9n

÷ -9 ÷-9

4= n

substitute:

-81= -45 -9 (4)

-81= -45 -36

-81= -81

-45 - 9n = -81

-9n = -81 + 45

-9n = -36

n = -36/-9

n = 4

Hope this helps you. :)

A rectangular prism with a volume of 45 cubic centimeters and a height of 3 cm has a base with an area of

olga55 [171]

Answer:

Area: 15cm^2

Base: 5cm

Step-by-step explanation:

The volume of a Rectangular Prism is given as:

V= wlh

Where W = Base

L = Length

H= Height

From the question:

The Volume V = 45cm^3

The Height H = 3

But, Area = Length * Width

Therefore :

Volume V = Area * Height

45 = A * 3

A = 45/3

A= 15cm^2

Solving for Base:

Area = height * Base

15 = 3 * Base

Base = 15/3

Base = 5cm

Find the nonpermissible replacement for y in the expression y+3/y+3

Ugo [173]

Answer:

Non-permissible value is $y=-3$

Step-by-step explanation:

we are given equation as

$f=\frac{y+3}{y+3}$

we know that denominator can not be zero

so, we can set denominator =0

and then we can solve for y

$y+3=0$

we can subtract both sides by 3

$y+3-3=0-3$

$y=-3$

So,

Non-permissible value is $y=-3$

Here goes another question: 4/5%9/10 and please if you can with procces

love history [14]

When you divide a fraction by another fraction, it is the same thing as multiplying that fraction by its reciprocal.

The reciprocal is the 'flipped' version of a fraction where the numerator becomes the denominator and the denominator becomes the numerator.

for example, the reciprocal of 9/10 is 10/9

Knowing this information 4/5÷9/10 is the same as 4/5×10/9

Now we can solve...

$\frac{4}{5} * \frac{10}{9} = \frac{40}{45} = \frac{8}{9}$

Answer= 8/9

using the pythagorean theorem find the area of an equilateral triangle whose side measures 7 units find the area to the nearest

Molodets [167]

<span>If you have an equilateral triangle, the median is also the altitude so - That means that if you draw altitude, it will bisect the base of the triangle and meet at two right angles. That gives you two of the measurements for the right triangle - the side (6) hypotenuse, and the base (3). You can then figure out the height using the Pythagorean as you have the a and the c for the theorem. Then you can use 1/2 base times height to find the area.
