Answer the following equations:
[tex]3^2+4^2=?^2[/tex]
[tex]5^2 +12^2=?^2[/tex]
[tex]7^2+24^2=?^2[/tex]

Answer:

I believe that 4 1/2 divided by 6 is the correct answer.

(It is the same as the expression you wrote next to "Regular." It is correct because it does not include an equal sign and correctly expresses the problem.)

Note: Do not include any work below the arrow when writing in the "Expression" section.

Please let me know if this is incorrect.

The shape of the image of ΔABC following a dilation by a scale factor of [tex]\dfrac{2}{3}[/tex] is the same as the shape of ΔABC but the sizes of the sides of ΔA'B'C' are [tex]\dfrac{2}{3}[/tex] smaller

The correct options with regards the given statements are;

Reasons:

The dilation lengths of the sides of ΔABC are AB, AC, BC

The given scale factor of dilation = [tex]\dfrac{2}{3}[/tex]

Therefore;

The lengths of the sides of ΔA'B'C' are [tex]\dfrac{2}{3} \cdot \overline {A'B'}[/tex], [tex]\dfrac{2}{3} \cdot \overline {A'C'}[/tex], [tex]\dfrac{2}{3} \cdot \overline {B'C'}[/tex]

Which gives;

[tex]\dfrac{\overline{A'B'}}{\overline{AB}}} = \dfrac{\overline{A'C'}}{\overline{AC}}} = \dfrac{\overline{B'C'}}{\overline{BC}}} = \dfrac{2}{3}[/tex]

Given that the ratio of the corresponding sides of ΔABC and ΔA'B'C' are equal, ΔABC is similar to ΔA'B'C' by triangle similarity theorem

Therefore;

∠A = ∠A', ∠B = ∠B', and ∠C = ∠C' by definition of triangle similarity

Which gives;

The statement; The measure of ∠B and ∠B' are equal is True

Second part;

The center of dilation of ΔABC is point A, therefore, the distance between point A and point A' following a dilation is zero

Therefore, given that there is no difference, we have;

The coordinates of point A = The coordinates of point A'

Therefore;

The statement, the coordinates of A and A' are the same is True

Answer:

False

True

Step-by-step explanation:

A dilation multiplies the distance of every point from the center of dilation by the scale factor. So a dilation moves every point except the center of dilation.

Point A is the center of dilation, so the coordinates of A and A′, are the same.

Dilations multiply every length in the figure by the scale factor, so AB and A'B' do not have the same length.

Step-by-step explanation:

61.25 is your answer.

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

Explanation:

We'll need to use the circumference formula

C = 2*pi*r

to find the value of the radius r when C = 44

So we get

C = 2*pi*r

44 = 2*3.14*r

44 = 6.28*r

6.28r = 44

r = 44/6.28

r = 7.0063694267516

which is approximate

Then we use this value of r to find the area we need

A = pi*r^2

A = 3.14*(7.0063694267516)^2

A = 154.140127388536

A = 154

The area of the circular placemat is approximately 154 square inches.

Answer:

a ~ 154

a = [tex]\frac{484}{(pi)}[/tex]

Step-by-step explanation:

1. Approach

In this problem, one is given the circumference, the distance around the circle, one must find the area. In order to find the area, one must know the radius of the circle. To find the radius, one has to backsolve from the given circumference, then substitute the derived value into the formula for the area and solve.

2. Find the radius

The formula to find the circumference of a circle is;

[tex]2r(pi)=c[/tex]

Where (r) is the radius, (pi) is (3.1415), and (c) is the circumference.

Substitute in the given values and solve;

[tex]2r(pi) = c\\2r(pi) = 44\\r=\frac{44}{2(pi)}\\r=\frac{22}{(pi)}[/tex]

3. Find the area

Now, one has the value of the radius, substitute it into the formula for the area of a circle and solve;

The formula for finding the area of a circle;

[tex](pi)r^{2}=a[/tex]

Where (pi) is (3.1415), (r) is the radius, and (a) is the area,

Substitute in the value and solve.

[tex](pi)r^{2} = a\\(pi)(\frac{22}{(pi)})^{2}=a\\\frac{(22)^{2}}{(pi)}=a\\\frac{484}{(pi)}=a[/tex]

a ~ 154

Answer:

The rectangle is the only one.

Step-by-step explanation:

Answer:

Yes, it is a solution.

Step-by-step explanation:

Since t ≥ 12 means that t needs to be equal to or greater than 12, t = 12 works as a solution because it is equal to 12.

Step-by-step explanation:

10 x 4 = 40 + 20 = 60

15 x 4 = 60

Answer:

401

Step-by-step explanation:

1. Approach

To solve this problem, one first has to think about the given figure in a certain way. In the figure, one can see that it is a circle attached on either side of a rectangle. To find the perimeter of the figure, one has to find the circumference of the circle and then add two sides of the rectangle to the answer

2. Circumference of the circle

The formula to find the circumference of a circle is;

[tex]2r[/tex](pi) or [tex]d[/tex](pi)

~ diameter times the value (pi)

Normally to find the circumference of a semicircle, one would have to divide this formula by 2, but since in this case, one has to add two congruent semicircles, so therefore, the effect of dividing the equation by two, only to multiply by two again cancels, and hence, there is no need to divide by 2.

Substitute in the values;

(78)(pi)

~ 245

3. Find the perimeter of the entire object

Now, one has to add the two additional sides of the figure, to the circumferences of the semicircles to get the final answer;

78 + 78 + 245

= 401

Answer:

10

Step-by-step explanation:

You can do 8 / 0.8 to get 10

Answer: 20% off means that the new price of the shoes will be 80% of the original price:

$30(100%  – 20%) = $30(80%)

Converting the percent to a decimal gives:

$30(0.8) = $24.00

There is an additional 15% off the sale price of $24.00, so the final price is 85% of the sale price:

$24(100%  – 15%) = $24(85%)

Again converting the percent to a decimal gives:

$24(0.85) = $20.40

Answer:

Step-by-step explanation:

The area of a triangle = 1/2 x base x height

The base here is 2 and the height is 3.

2 x 3 = 6

1/2 x 6 = 3

Answer:

3

Step-by-step explanation:

To find the area of a triangle you have to do 1/2 bh (one half times the base times the height). So when you do 3 x 2 (Since those are the side lengths) you would get 6 then divide by 2 to get 3.

Hope this helps :)

Answer:

y=1 and x=1

Answer:

8 mph

Step-by-step explanation:

Answer:

the answer is 8

Step-by-step explanation:

2 times 8 equals 16 16 plus 8 equals 24

Answer:

x = 6

Step-by-step explanation:

3 (2x - 5) = 21

=> 6x - 15 = 21

=> 6x = 21 + 15

=> 6x = 36

=> x = 36 / 6

=> x = 6

OR

3 (2x - 5) = 21

=> 2x - 5 = 21 / 3

=> 2x - 5 = 7

=> 2x = 7 + 5

=> 2x = 12

=> x = 12 / 2

=> x = 6

Hope it helps :)
