The expression -2x² + 90x +500 represents the area of the rectangle if the length and width of the rectangle are (50 - x) and (2x + 10) option (c) is correct.

What is the area of the rectangle?

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

Area of rectangle = (50 - x)(2x+10)

[tex]\rm -2x^2+90x+500[/tex]

Thus, the expression -2x² + 90x +500 represents the area of the rectangle if the length and width of the rectangle are (50 - x) and (2x + 10) option (c) is correct.

Maria has $3,000 in the bank, has a home worth $150,000, and has a $75,000 home loan. She also has $10,000 in Investments and a $15,000
student loan. What is Maria's net worth? Show your work please

Answers

Answer:

$73,000

Step-by-step explanation:

To answer, you simply subtract and add numbers along the way. First, because Maria has money in the bank and her home is worth money, we add those numbers together:

3,000 + 150,000 = 153,000

Now, because she has a home loan, that means she owes money, so you subtract that from her net worth so far:

153,000 - 75,000 = 78,000

Her investments money would be added:

78,000 + 10,000 = 88,000

And another student loan would be subtracted:

88,000 - 15,000 = 73,000

So, Maria's net worth is $73,000

Answers

Answer:

Step-by-step explanation:

sin(t) = -3√10/10

cos(t) = √10/10

tan(t) = sin(t)/cos(t) = -3

csc(t) = 1/sin(t) = -√10/3

sec(t) = 1/cos(t) = √10

cot(t) = 1/tan(t) = -⅓

Answers

Answer:

Karla's 15 miles per week to Brad's 17 miles per week.

Step-by-step explanation:

First, we would need find the total number of miles each individual rides per week. We do this by dividing the total miles ridden by the number of weeks it took for each individual like so...

Karla:  135 / 9 = 15 miles per week

Brad:   102 / 6 = 17 miles per week

Finally, the comparison would be

Karla's 15 miles per week to Brad's 17 miles per week.

Answer:

Eric rode 2 more miles per week than Kim rode
