x coordinate of D  =  distance of 9 - 1 = 8 from point M

y coordinate of D  =  4-2 = 2  from point M

so coordinates of D are (--1+8 , -2 + 2)  = (7 , 0)  answer

Ira Lisetskai [31]

Answer:


Step-by-step explanation:

4/5 cup of brown sugar. Needs 1/4 cup. How many cups left?

Okay, so 4/5 = 0.80, 1/4=0.25.

0.80-0.25=0.55

Which is 55/100

Divide both numbers by 5

Based on housing data below which equation can be used to calculate fair housing prices?
VMariaS [17]

Answer:

B. y = 0.097x + 11.142

Step-by-step explanation:

In order to find the best equation to descibe the housing price, we have to calculate the slope of the line  first.

The equation of the line can be written as

y=mx+q

where m is the slope and q the y-intercept.

In order to have the most accurate estimate for the slope, we use the first point and the last point, that are:

(1900, 196)

and

(2200, 225)

The slope of the line is calculated as:

m=\frac{y_2-y_1}{x_2-x_1}=\frac{225-196}{2200-1900}=0.097

So, the slope of the line is 0.097.

Therefore, the correct option is the only one having a slope of 0.097, which is:

B. y = 0.097x + 11.142

Determine the area of each semicircle or quarter circle. Think carefully about whether the length you are given corresponds to a
VashaNatasha [74]

Answer:

Area of semicircle = 1/2(πr^2)

Area of quarter circle = 1/4(πr^2)

Step-by-step explanation:

The question is incomplete. You didn't provide the diagrams for the semicircle and quarter circle to evaluate the areas. I would explain how to find the area of a semicircle and quarter circle.

Area of a circle = πr^2

where r = radius and π = 3.14

If diameter (d) is given: d = 2r

To get radius, divide diameter by 2.

r = d/2

A semicircle is half of a circle.

Area of a semicircle is half the area of a circle.

Area of a semicircle = 1/2(πr^2)

A quarter circle is a quarter of a circle.

Area of a quarter circle is quarter of the area of a circle.

Area of a quarter circle = 1/4(πr^2)

Further explanation with diagram has been added as as an attachment.

"Find the missing side lengths in each pair of similar figures." Someone explain please
Lana71 [14]
AB is proportional to XY since they are similar triangles making it 25:10 or 5:2
so then AC:XZ  would be 5x:2x and 5x:6 so then its 15:6 since x is 3 basically set up proportions and so value of the big triangle to the small triangle would be at rails os 5:2
