Answer:

The other length would be 6.

Step-by-step explanation:

Rectangle area is l times height. So x is either the length for height. So we have 5 times x = 30. To find the other length we have to take 30/5 which equals 6

Answer:

D is the correct one

Step-by-step explanation:

The whole angle equals 72 and the partial angle equals 45

You put

72-45= 27

So 3x=27

Then you solve this equation

3x = 27

x = 27/3

x = 9

The measure of x= 9 with angle 45

Vertical angles are angles opposite each other where two lines cross.

given:

3x = 45  (vertically opposite angle)

x=9

Answer:

[tex]\huge\boxed{50}[/tex]

Step-by-step explanation:

In order to solve for this number, we have to create a percentage proportion.

We know that 24 is 48% of something, so we can create a ratio like this:

[tex]\frac{24}{x}=\frac{48}{100}[/tex]

We can then cross multiply and then divide to find the value of x.

[tex]24 \cdot 100 = 2400[/tex]

[tex]2400 \div 48 = 50[/tex]

So 24 is 48% of 50.

Hope this helped!

48 percentage of the number 50 is 24.

To find the number, you can set up an equation where 48% of that number is equal to 24.

Let's represent the unknown number as "x."

48% of x is written as 0.48x.

Setting up the equation:

0.48x = 24

To solve for x, divide both sides of the equation by 0.48:

x = 24/0.48

Evaluating this expression:

x = 50

Therefore, 48% of 50 is 24.

Answer:

22 < x < 74

Step-by-step explanation:

Given 2 sides of a triangle with third side x , then

difference of 2 sides < x < sum of 2 sides , that is

48 - 26 < x < 48 + 26 , so

22 < x < 74

Answer:

  salt, super clean, pepper, washing powder

  44oz drink, popcorn, 32oz drink

Step-by-step explanation:

The number of ounces can be found by dividing the price by the price per ounce:

  3.60/(0.30/oz) = 12 oz . . . salt

  8.80/(0.11/oz) = 80 oz . . . super clean

  6.72/(0.42/oz) = 16 oz . . . pepper

  7.80/(0.13/oz) = 60 oz . . . washing powder

__

  3.52/(0.08/oz) = 44 oz . . . 44oz drink

  9.00/(0.18/oz) = 50 oz . . . popcorn

  1.92/(0.06/oz) = 32 oz . . . 32oz drink

Answer:

22w + 115 = 325           w = about 10 weeks

Step-by-step explanation:

The first part of this inequaltiy is 22w. Since he/she will set aside $22 a week, you would put a variable because the number of weeks you will need to set aside $22 is unknown therefore you put a variable that makes sense. I put w because you can say that w=weeks. The next part of the inequality is adding $115 because he/she has already saved $115 so we add that to 22w. Finally 22w+115 has to equal $325 because that is how much the necklace costs. Hope this helps!

Answer:   {(x + 2), (x - 1), (x - 3)}

Step-by-step explanation:

Presented symbolically, we have:

x^3 - 2x^2 - 5x + 6

Synthetic division is very useful for determining roots of polynomials.  Once we have roots, we can easily write the corresponding factors.  

Write out possible factors of 6:  {±1, ±2, ±3, ±6}

Let's determine whether or not -2 is a root.  Set up synthetic division as follows:

-2   /   1   -2   -5   6

              -2     8   -6

     -----------------------

        1     -4      3    0

since the remainder is zero, we know for sure that -2 is a root and (x + 2) is a factor of the given polynomial.  The coefficients of the product of the remaining two factors are {1, -4, 3}.  This trinomial factors easily into {(x -1), (x - 3)}.

Thus, the three factors of the given polynomial are {(x + 2), (x - 1), (x - 3)}

C(20)=$57.08

Step-by-step explanation:

Exponential Decay Function

The exponential function is often used to model natural growing or decaying processes, where the change is proportional to the actual quantity.

An exponential decaying function is expressed as:

[tex]C(t)=C_o\cdot(1-r)^t[/tex]

Where:

C(t) is the actual value of the function at time t

Co is the initial value of C at t=0

r is the decaying rate, expressed in decimal

The depreciation of goods is often modeled as an exponential function. The new car costs $18,000 and its price depreciates at r=25%= 0.25 every year.

The depreciation model is:

[tex]C(t)=18,000\cdot(1-0.25)^t[/tex]

Operating:

[tex]C(t)=18,000\cdot 0.75^t[/tex]

At t=12 years, the price will be:

[tex]C(12)=18,000\cdot 0.75^{12}[/tex]

C(12)=$570.18

At t=20 years, the price will be:

[tex]C(20)=18,000\cdot 0.75^{20}[/tex]

C(20)=$57.08

Answer:

A

Step-by-step explanation:

To get the answer here, we simply start looking from what we had initially

From the initial point, we can see that line p and line r are perpendicular

The reason for this is because, line q serves as a point for the two and since q is perpendicular to p and r, then p and r are perpendicular

So since s is parallel to like p and line p

is perpendicular to r, then r and and s must be parallel too

Answer:  Choice C

XY < YZ < ZX

=================================================

Explanation:

Check out the diagram below

Angle X = 70

Angle Y = 88

Z is the unknown angle. The three angles of any triangle always add to 180

X+Y+Z = 180

70+88+Z = 180

Z+158 = 180

Z = 180-158

Z = 22

Angle Z is 22 degrees.

Since Z is the smallest angle, this means the side opposite that is the smallest side. The smallest angle is always opposite the smallest side, and vice versa. So XY is the smallest side.

The largest side is always opposite the largest angle. Here we have angle Y = 88 as the largest, so side ZX is the largest side.

The order of the sides from smallest to largest is

XY < YZ < ZX

Answer:

x= 13.5

Step-by-step explanation:

f(x) = 2x + 9

f(x) = 36

Set the 2 equations equal to each other;

2x + 9 = 36

Subtract 9 from both sides;

2x = 27

Divide both sides by 2;

x = 13.5

Check:

f(x) = 2x + 9

f(13.5) = 2(13.5) + 9= 27 + 9 = 36
