Kendall is starting a new small business and working everyday to make it a success. She earned $952 in 7 days. Assume she will c

n200080 [17]

Answer:

$4080 / 30days

Step-by-step explanation:

In 7 days, Kendall earns $952

In 1 day, she will earn $952 ÷ 7 = $136

Therefore, the rate (r) at which she earns is $136/day. i.e

r = $136/day ---------------(i)

To write the rate as a fraction with 30 in the denominator, we multiply both the numerator and denominator of equation (i) by 30 as follows;

r = $(136x30) / 30 day

r = $4080/30days

Answer:

Mark as brainliest if helped Thanks!

Step-by-step explanation:

funtion is:

$y = \frac{x^2 -1}{2x + 1}$

therefore $\\\frac{dy}{dx}\\$ is

$\frac{d\frac{x^2 -1}{2x + 1}}{dx}$

$\frac{\frac{x^2 -1}{2x + 1}}{x}$

$\frac{x^2 -1}{(2x+1) x}$

Now

$\int\limits^2_0 {\frac{x^2 +x +1 }{4x^2 +4 + 1} } \, dx$

(Calculation of this it too long and it is hard to type on brainly)

here is the answer though....

= 4/5

=0.8

Elena knows dad 5 servings and granola has 1750 calories how many calories are in one serving of granola

aalyn [17]

If you have information about 5 servings, assuming that all servings have the same calories, the information about one serving is simply obtained by dividing the total by 5.

So, each serving has

$\dfrac{1750}{5} = 350$

calories
