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.

The admission fee at a zoo is $2 for children and $4 for adults. If 1800 people enter the zoo and $6000 is collected, how many a
ipn [44]

Answer:

The number of adults is 1,200

Step-by-step explanation:

Let

x------> the number of children

y------> the number of adults

we know that

x+y=1800 -------> equation A

2x+4y=6000 -------> equation B

Multiply equation A by -2

-2(x+y)=-2*1800 --------> -2x-2y=-3600 ------> equation C

Adds equation B and equation C

2x+4y=6000\\-2x-2y=-3600\\---------\\4y-2y=6000-3600\\2y=2400\\y=2400/2\\y=1200

How to solve function operations
Mama L [17]
" Given f (x) = 3x + 2 and g(x) = 4 – 5x, find (f + g)(x), (f – g)(x), (f × g)(x), and (f / g)(x).1. = [3x + 2] + [4 – 5x] = 3x + 2 + 4 – 5x. = 3x – 5x + 2 + 4. = –2x + 6. (f – g)(x) 2. = f (x) – g(x)= [3x + 2] – [4 – 5x] = 3x + 2 – 4 + 5x. = 3x + 5x + 2 – 4. = 8x– 2. 3. ...= (3x + 2)(4 – 5x) = 12x + 8 – 15x2 – 10x. = –15x2 + 2x + 8. " - Google
