Answer:

d)  XY = 15.75

Step-by-step explanation:

XY is the median of the trapezoid

XY = (DC + AB) ÷ 2

XY = (13.4 + 18.1) / 2

Answer:

Reflect over x-axis, Translate 5 units right, Dilate by a factor of 2

Step-by-step explanation:

I think this is correct The dilation probably isn't but those are the three transformations. But i am pretty sure i am right.

Answer:

steps below

Step-by-step explanation:

A(-1,-1)   B(-2,-3)  C(-3,-1)

1. Reflection over y=-1    A(-1,-1)   B(-2,1)  C(-3,-1)

2. Shift to right 4 units   A(3,-1)   B(2,1)  C(1,-1)

3. Dilation with factor 2 and center C'(1.-1)      A'(5,-1)   B'(3,3)  C'(1,-1)

Answer:

113.1 inches squared

Step-by-step explanation:

Answer:

the answer is 113.1

Step-by-step explanation:

given

d=12

diameter is half of the radius

so

r=6

now we apply the formula

A=22/7 × 6×6

=792/7

=113.1

i hope the answer is right

Answer:

[tex]25ab {c}^{2} - 15 {a}^{2} {b}^{2} c \\ = 5abc(5c -3ab)[/tex]

is the right answer.

Answer:

9, 13, 17

Step-by-step explanation:

The difference between the greatest value and the least is 8, the range.

Add the three numbers to total 39, then divide by 3 to get the mean, 13.

Answer:

2.79

Step-by-step explanation:

Given

With reference angle 21°

hypotenuse (h) = 3

base (b) = x

Now

cos 21° = b / h

0.93 = x / 3

x = 0.93 * 3

x = 2.79

Hope it will help :)

Answer:

z = 5

Step-by-step explanation:

m = ∆y/∆x = y₂-y₁/x₂-x₁

0 = y₂-y₁/x₂-x₁ = 5 - z / -7 - 9 = 5 - z / -16 →

5 - z / -16 = 0 → 5 - z / -16 × -16 = 0 × -16 → 5 - z = 0 →

5 - z - 5 = 0 - 5 → -z = -5 → z = 5

180- 2(65) = 52

Answer:

12x-72

x=8

3x-3

x=-3

Step-by-step explanation:

SOLUTION:

First, find the constant of variation k using the equation k=(x)(y)

[tex]3 = \frac{k}{ \frac{2}{3} } [/tex]

[tex]k = (3)( \frac{2}{3} )[/tex]

[tex]k = 2[/tex]

-----------------------

Then, find the value of y.

Answer:

$149.50

Step-by-step explanation:

Width = x

Length = 2x - 5

Perimeter of the room = 5x

Perimeter of the room = 2(length + width)

5x = 2{(2x-5) + x}

5x = 2(2x - 5 + x)

5x = 4x - 10 + 2x

5x = 6x - 10

5x - 6x = -10

-x = -10

x = 10

Width = x = 10

Length = 2x - 5

= 2*10 - 5

= 20 - 5

= 15

Perimeter of the room = 5x

= 5 × 10

= 50 square foot

If carpet costs $2.99 a square foot, what the total cost to carpet the living room

Total cost = $2.99 × 50

= $149.50

Answer:

C. 12°

Step-by-step explanation:

Answer:

180 dollars

Step-by-step explanation:

if it was discounted by 30 percent, that means 126 is 70 percent of the orin=inal price. If you divide 126 by 70, you get 1.8 is the money worth 1 percent. Multiply 1.8 by 100 to get the original price, and you end up with 180 dollars.

Answer:

Explanation:

We have 5 slices shaded out of 8 total. Therefore, we have 5/8 = 0.625 = 62.5% of this figure is shaded.

Answer:

62.5%

Step-by-step explanation:

Answer:

f(x) = -5x -1

Step-by-step explanation:

For each change in x there is a -5 change in y so the slope is y = -5x

If x was 0 y would be -1 so the y-intercept is -1

Answer:

x = 3 answer in the squire root is 5 what times itself = 5? youre answer will be 2.2360679775

Step-by-step explanation:

Answer:

Slope and y intercept.

Step-by-step explanation:

This is necassary to write the equation of a line in y=mx+b

m is where the slope goes, and b is the y intercept.

Alternatively, you could also write the equation for a line with a point on the line and the slope.

You would then write it in point slope formula:

y-y1=m(x-x1)

This can later be converted into slope intercept form.

Answer:

When asked to write an equation, you need to know two things – slope (m) and y-intercept (b).

Or

The Standard Form for a linear equation in two variables, x, and y, is usually given as Ax + By = C where, if at all possible, A, B, and C are integers, and A is non-negative, and, A, B, and C have no common factors other than 1.

Answer:

4w

Step-by-step explanation:

4w means 4 times w, and if you have four groups of something, you multiply it to see how much there is.

Answer:

4times(x)w

Step-by-step explanation:

Answer:

x,x+1,x+2

Step-by-step explanation:

x+2[x+1]+3[x+2]= -76

x+2x+2+3x+6= -76

6x+8=-76

6x=-76-8

6x= -84

x= -84/6

x= -14
