If you substitute the value 22.5 for h into the equation


h = 11.25, does it make the statement true or false?

Answer:

Step-by-step explanation:

How many selfies did Tania take? (my first answer would be too many, but that's probably not the answer you're looking for :-) )

We know that each cousin appear 2 or 3 times overall.

If she would have taken each cousin exactly 2 times, that would be 16 cousins/photos

If she would have taken each cousin exactly 3 times, that would be 24 cousins/photos

We know there's exactly 5 cousins per photo...

so we have to find a multiple of 5 cousins/photos that is between 16 and 24.

The only possibility is 20 cousins/photos.  20 / 5 = 4 photos.

Answer:

Square root of 16 = 4

Square of 16 = 256

Hope this helps :)

Have a great day !

Step-by-step explanation:

X=11 because 90-43+5x-8 so 5•11=55-8 =47 90-43=47

Complementary means the angles together would equal 90°. Supplementary means the angles would equal 180°.

Using Complementary angles:

5x-8+43=90 Combine -8 and 43 = 35

5x+35=90

-35 -35

5x=55

Divide each side by five

x=11

The missing length of the missing side is x+1.

To find the perimeter of this object, we need to know hat perimeter truly means.

Perimeter-The sum of all the sides.

The sides from the trapezoid are 3x+1, x , and x.

We combine like terms, so 3x + x + x = 5x

1 is the only number.

We are left off with 5x+1. Our objective is to get 6x+2.

How do we get there? We add 1x or x (1x and x) are the same thing, and we add one.

5x+1 + 1x + 1 = 6x+2;

Therefore the renaming length of the missing side is 1x+1.

Answer:

x + 1

Step-by-step explanation:

Is that a lone x on the left hand side? I will assume so.

Let y be the value of the side marked with a ?.

x + 3x + 1 + x + y = 6x + 2     collect the like terms on the left.

5x + 1 + y= 6x + 2                  Subtract 1 from both sides.

5x + 1-1 +y = 6x + 2-1             Combine

5x + y = 6x + 1                        Subtract 5x from both sides.

5x-5x + y = 6x -5x +1             Combine

y =x + 1

The missing side is x +1

Answer:

The dimensions of the porch are [tex]25\ ft[/tex]  by [tex]20\ ft[/tex]

Step-by-step explanation:

we know that

The area of the porch is equal to the length multiplied by the width

[tex]A=(2x+3)(x+9)[/tex]

[tex]A=500\ ft^{2}[/tex]

so

[tex]500=(2x+3)(x+9)[/tex]

Solve for x

[tex]500=2x^{2} +18x+3x+27\\ \\2x^{2} +21x-473=0[/tex]

Solve the quadratic equation by graphing

The solution is [tex]x=11\ ft[/tex]

The dimensions are

[tex](x+9)=11+9=20\ ft[/tex]

Answer:

  Square

Step-by-step explanation:

The length of AB is (a+b)-a = b. The length of BC is b-0 = b. So, adjacent sides are the same length. AB has a constant y-value, so is horizontal. BC has a constant x-value, so is vertical.

A figure with horizontal and vertical sides of the same length is a square.

Answer:

80π feet/ second.

Step-by-step explanation:

Angular velocity of a point = 10π radians per second

Radius of the circle is 8 feet.

We know the formula of angular velocity is

Angular velocity = [tex]\frac{speed}{radius}[/tex]

10π = [tex]\frac{speed}{8}[/tex]

Speed = 80π feet/ second.

Option C is the answer.

Answer: [tex]80\pi\text{ ft/sec}[/tex]

Step-by-step explanation:

Formula : [tex]\text{Speed= Angular velocity x Radius}[/tex]   (1)

We are given that , The angular velocity of a point with radius 8 feet is 10 pi radians per second.

i.e. Radius = 8 feet

Angular velocity = [tex]10\pi[/tex] radians per second.

Then, the speed of the point will be :-

[tex]\text{Speed= }10\pi \times 8[/tex]   [using (1)]

[tex]=80\pi\text{ ft/sec}[/tex]

Hence, the speed of the point [tex]=80\pi\text{ ft/sec}[/tex]

Answer:

The slope is 0. However, it is a horizontal line where x=-6.

Step-by-step explanation:

Use the equation m= y2-y1/x2-x1 to get 12--8/-6--6. Two negatives means a positive, so you get 20/0. This means there is no slope, because you cannot divide by 0. However, you notice that both x-values are -6, so you can safely assume that there is a horizontal line where x=-6.

The slope is undefined and the line is vertical and parallel to the y-axis.

Given points (-6, -8) and (-6, 12)

First, the slope of line is

Slope= (change in y/ change in x

         = (12 - (-8)) / (-6 - (-6))

         = (12 +8) / (-6 +6)

         = 20 /0

         = ∞

Since we have a division by zero in the denominator, the slope is undefined.

This indicates that the line is vertical and parallel to the y-axis.

Thus, the slope is undefined.

Answer:

The answer would be m= -9

Step-by-step explanation:

6(9-m)

You will multiply the 6 with the 9 and -m inside of the parenthesis

54-6m

Divide by -6 on both sides and you will get m= -9

I hope this helps you with this question and have a nice weekend

The equivalent expression to 6(9 - m) is 54 - 6m, determined by applying the distributive property of multiplication over addition and subtraction.

The expression given is 6(9 - m). To identify an expression equal to this, we should look for expressions that maintain the same relationship between the numbers and the variable m. When we distribute the 6 across the parentheses, we multiply 6 by 9, and 6 by -m, resulting in 54 - 6m.

Distributing a number across a subtraction in a parenthesis follows the distributive property of multiplication over addition and subtraction, which allows us to multiply each term inside the parentheses by the number outside.

=$499.80

Answer:  

Simple Interest over the given time interval will be $5.80

Step-by-step explanation:

Principal Amount = $580

Rate of Interest = 2%

                          = 0.02

Time = 6 months

        = 0.5 years

Now, Simple Interest is given by the formula :

Simple Interest = Principal × Rate × Time

⇒ Simple Interest = 580 × 0.02 × 0.5

⇒ Simple Interest = $5.80

Thus, Simple Interest over the given time interval will be $5.80

Answer:

[tex]f(x) = 6x -12[/tex]

Step-by-step explanation:

We must write the function of the line in the form [tex]f (x) = mx + b[/tex]

First calculate the slope m

[tex]m =\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]y_2 = 18\\y_1 =6\\x_2=5\\x_1=3[/tex]

[tex]m= \frac{18-6}{5-3} = 6[/tex]

Then

[tex]f(x) = 6x +b[/tex]

To have b replaced a point in the function

[tex]f(3)=6 = 6(3) +b\\\\6-18= b\\\\b=-12[/tex]

Finally the function is

[tex]f(x) = 6x -12[/tex]

ANSWER

[tex]f(x) = 6x - 12[/tex]

EXPLANATION

The given line passes through the points (3, 6) and (5, 18).

The slope of this line given by:

[tex]m = \frac{y_2-y_1}{x_2-x_1} [/tex]

We plug in the points to get,

[tex]m = \frac{18 - 6}{5 - 3} = \frac{12}{2} = 6[/tex]

The equation is given by

[tex]y-y_1=m(x-x_1)[/tex]

We plug in the point and the slope to get,

[tex]y - 6 = 6(x - 3)[/tex]

[tex]y - 6 = 6x - 18[/tex]

[tex] y = 6x - 18 + 6[/tex]

[tex]y = 6x - 12[/tex]

Using function notation, we have

[tex]f(x) = 6x - 12[/tex]

Step-by-step explanation:

Solve for x

- 4 (x - 2) = - 4           There are a a couple of ways of doing this. Divide by - 4

-4 (x - 2)/-4 = - 4/-4   Combine

x - 2 = 1                     Add 2

x = 3

Solve for y

9 + 2(y - 3) = 3(y - 2) + 1        Remove the brackets on both sides.

9 + 2y - 6 = 3y - 6 + 1           Combine

9 - 6 + 2y = 3y - 5                

3 + 2y = 3y - 5                      Add 5

3 + 5 + 2y = 3y                      Subtract 2y

8 + 2y - 2y = 3y - 2y

8 = y

Solve for z

z/3 + 1/2 = 5/2                       Subtract 1/2 from both sides.

z/3 + 1/2 - 1/2 = 5/2 - 1/2       Combine

z/3 = 4/2

z/3 = 2                                   Multiply by 3

z/3*3 = 2*3

z = 6

So far what you have is
