Answer:

Step-by-step explanation:

What i would do is turn the first one into an improper fraction

7/5 x 1/4

it's easier to multiply this way

see if you can simplify any of the terms first

7 1

5 4

none of the numbers can be broken down further so we just multiply straight across

7 x 1 is 7

5 times 4 is 20

so the answer would be 7/20

Makenzie is looking to purchase a used Jeep Wrangler that costs $21,000. She will make a $4,000 down payment and borrow the rema

olga_2 [115]

Answer:

$323

Step-by-step explanation:

The monthly payment can be calculated using the formula:

$M=\frac{P(\frac{r}{12})(1+\frac{r}{12})^n}{(1+\frac{1}{12})^n-1}\\\\$

where:

M=monthly payment
P=amount borrowed
r=annual interest rate
n=total number of monthly payments:

Our parameters are defined as:

$n=60\\P=21000-4000=17000\\r=5.3%\\\\$

We plug our parameters in the equation to solve for M;

$M=M=\frac{P(\frac{0.053}{12})(1+\frac{0.053}{12})^n}{(1+\frac{0.053}{12})^{60}-1}\\\\\\\\$

$=\frac{P(\frac{0.053}{12})(1+\frac{0.053}{12})^{60}}{(1+\frac{0.053}{12})^{60}-1}\\\\\\=323.15$

$=323.15\approx\$323$

Hence, the monthly payment is $323

Find the surface area of a cylinder that has a raius of 13.5 cm., and a height of 90 cm. Show all work without using a calculato

professor190 [17]

$\bf \textit{surface area of a cylinder}\\\\ SA=2\pi r(h+r)~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=13.5\\ h=90 \end{cases}\implies SA=2\pi (13.5)(90+13.5) \\\\\\ SA=27\pi (103.5)\implies SA=2794.5\pi \implies SA\approx 8779.18$

well, the last part will be with a calculator, but you can simply use the area in π terms.
