Answer:

1) D. m\angle B=130^o

2) D. $122 million.

Step-by-step explanation:

1. We have been given two similar figures and we are asked to find the measure of angle B.

Since we know that corresponding angles of similar figures are equal.

We can see from our given figures that the measure of angle corresponding to angle B is 130 degrees, therefore, the measure of angle B is 130 degrees and option D is the correct choice.

2. We have been given a scatter plot that shows a regression line of advertising dollars spent and sales.

To find the predicted sales, when company spent $350,000 on advertising, we need to find the y-value corresponding to x= 350 as x-axis represents the advertising cost in thousand dollars.

We can see from our attached file that at x=350 the corresponding y value is 122.

Since y-axis represents the sales in millions, so the predicted sales of company will be $122 million and option D is the correct choice.

Because the two triangles are similar, their angles will be the exact same.

Therefore, Angle B is 130 degrees

The answer is D.


There isn't a graph to look at for the second question so I can't help you on that one

(x+2)(2x+1)+(x+2)(2x-3) factorizar
koban [17]

Answer:

(x + 2)(4x - 2).

Step-by-step explanation:

(x+2)(2x+1)+(x+2)(2x-3)

Note that  (x + 2) is common to 2 parts of the expression. So we have:

(x + 2)(2x + 1 + 2x - 3)

= Ix + 2)(4x - 2)

Jordan and Sydney work at a dry cleaners ironing shirts. Jordan can iron 20 shirts per hour, and Sydney can iron 25 shirts per h
KiRa [710]

Answer: Jordan worked for 10 hours and Sydney worked for 6 hours.

Step-by-step explanation:

Let x represent the number of hours

that Jordan worked.

Let x represent the number of hours that Sydney worked.

Jordan can iron 20 shirts per hour, and Sydney can iron 25 shirts per hour. They ironed 350 shirts between them. It means that

20x + 25y = 350- - - - - - - - - - - 1

Jordan worked 4 more hours than Sydney. It means that

x = y + 4

Substituting x = y + 4 into equation 1, it becomes

20(y + 4) + 25y = 350

20y + 80 + 25y = 350

20y + 25y = 350 - 80

45y = 270

y = 270/45

y = 6

x = y + 4 = 6 + 4

x = 10

A man travels from town X to town Y at an average rate of 60 mph and returns at an average rate of 50 mph. He takes a 1/2 hour l
yawa3891 [41]
<span>Distance = d miles ; rate = 60 mph ; time = d/60 hrs

distance = d miles ; rate = 50 mph ; time = d/50 hrs
----------------------
Round-trip DATA:
distance = 2d miles ; rate = 55 mph ; time = (2d)/55 hrs
-----------------------------------------------------------
Equation:

Roundtrip time - other time = -1/2 hr
(2d)/55 - [(d/60)+(d/50)] = -1/2
(2d)/55 - [(110d)/(50*60)] = -1/2
---
600(2d) - 11[110d] = -16500
1200d - 1210d = -16500
-10d = -16500
distance = 1650 miles

Hope this helped :)</span>
