Answer:

x = - 3 and y = - 8

Step-by-step explanation:

the equation of a vertical line parallel to the y- axis is

x = c ( c is the value of the x- coordinates the line passes through )

the line passes through (- 3, - 8 ) with x- coordinate - 3 , then

x = - 3 ← equation of vertical line

the equation of a horizontal line parallel to the x- axis is

y = c ( c is the value of the y- coordinates the line passes through )

the line passes through (- 3, - 8 ) with y- coordinate - 8 , then

y = - 8 ← equation of horizontal line

Consider the dot plot which shows the distribution of data collected on the amount of time Jason sleeps each night. Find the dif

Tatiana [17]

Answer:

A) 0.2

Step-by-step explanation:

From least to greatest, the data points are

6, 6, 6, 7, 7, 7, 8, 8, 8, 9

To find the mean, we find the sum of the data points and divide by the number of data points, 10. The sum of the data points is

6+6+6+7+7+7+8+8+8+9 = 72

Dividing by 10, the mean is 72/10 = 7.2.

The median is the middle number in the set. This is 7.

The difference between the mean and the median is

7.2-7 = 0.2.

Giuliana has 22 quarters and dollar coins worth a total of $10.75

nataly862011 [7]

Quarter is $0.25
Dollar is just $1
x is amount of quarters
y is amount of dollar coins
Two equations we know
0.25x+1y=10.75 and
x+y=22

solve both for y
0.25x+1y=10.75
y=10.75-0.25x

x+y=22
y=22-x

set them equal
22-x= (y) =10.75-0.25x
11.25=0.75x
x=15 quarters

then put x=15 into either equation and now solve for y

x+y=22
15+y=22
y=7 dollar coins

A pentagonal prism has a base area of 124 square inches. The lateral area (area of the sides) is made up of 5 equal-sized rectan

wel

The surface area of the pentagonal prism is 648 square inches.

Step-by-step explanation:

Step 1:

The surface area of a shape is the sum of all the areas of all the external surfaces.

The pentagonal prism has a total of 7 sides i.e. 2 pentagonal sides and 5 rectangular sides.

The total surface area of the prism is the sum of the individual areas of the 7 sides.

Step 2:

The area of the 2 pentagonal sides $= 2(124) = 248$ square inches.

The area of each rectangular side is 80 square inches. So

The area of 5 rectangular sides $= 5(80) = 400$ square inches.

The total surface area of the prism $=248+400 = 648$ square inches.

The surface area of the pentagonal prism is 648 square inches.
