Answer:

5.25 hours

Step-by-step explanation:

So in a week there is 7 days and we know she reads <em><u>EACH</u></em> night 0.75 so we know we have to multiply:

0.75 x 7= 5.25

So In one week or 7 days she read 5.25 hours.

Amanda want to pay the same amount each month on her car loan. The number of payments varies inversely with the monthly payment

Oxana [17]

Answer:

Her monthly payment would be $280.

Step-by-step explanation:

Same amount of $ per month

175 times 48 equals 8,400

(175 = monthly payment, 48 = amount of months)

8,400 divided by 30 equals 280

(8,400 = total amount of money, 30 = amount of months)

This makes the months = money ratio:

30 months = $280.

Solve for x. 5^11x=25^x+9

4vir4ik [10]

$\displaystyle\\
5^{11x}=25^{x+9}\\\\
5^{11x}=\Big(5^2\Big)^{x+9}\\\\
5^{11x}=5^{2(x+9)}\\\\
11x = 2(x+9)\\\\
11x = 2x+18\\\\
11x - 2x = 18\\\\
9x = 18\\\\
x = \frac{18}{9} = \boxed{2}$

Heeeeeeelp pleasee pleasee

I'm going to convert all the values given to you in percentages, so hopefully you should be able to see the correct answer a little clearer. :)

Debbie said that 21/50 drink coffee in the morning. 21/50 can also be written as 42/100, and now that it's out of 100, it's basically a percentage. (42%).

Allen said that 45% of people drink coffee in the morning. His value is already written as a percentage, so we won't do anything with it.

Benny says that 0.495 of the people he surveyed drink coffee in the morning. 0.495 is the same as 49.5% (multiply it by 100 to get it in a percentage).

So, in Debbie's survey, 42% of people drink coffee.
In Allen's survey, 45% of people drink coffee.
In Benny's survey, 49.5% of people drink coffee.

Therefore, the answer is Benny's survey. :)

If f(x) is a linear function, f(−2)=4, and f(1)=−1, find an equation for f(x)

juin [17]

Answer:

$y = -\frac{5}{3}x+\frac{2}{3}$

Step-by-step explanation:

Given

$f(-2) = 4$

$f(1) = -1$

Required

The equation of the function

The given parameters means that:

$(x_1,y_1) = (-2,4)$

$(x_2,y_2) = (1,-1)$

Calculate the slope (m)

$m = \frac{y_2 -y_1}{x_2 -x_1}$

$m = \frac{-1-4}{1--2}$

$m = \frac{-5}{3}$

The equation is then calculated using:

$y = m(x - x_1) + y_1$

This gives:

$y =\frac{-5}{3}(x--2)+4$

$y =\frac{-5}{3}(x+2)+4$

Open bracket

$y = -\frac{5}{3}x-\frac{10}{3}+4$

Take LCM

$y = -\frac{5}{3}x+\frac{-10+12}{3}$

$y = -\frac{5}{3}x+\frac{2}{3}$

nora has 3/4 as many books as victor. let v represent the number of books victor has. create an expression to represent the numb

xxTIMURxx [149]

Answer:

N = $\frac{3}{4}$ * v

Step-by-step explanation:

Since the value that we are provided is a fraction that is tied to the number of books that Victor has, we would simply need to multiply this fraction by the total number of books that Victor has. This value is represented by the variable v while the total number of books that Nora has is represented by the variable N. Therefore, the expression would be the following

N = $\frac{3}{4}$ * v
