Answer:

4 cans

Step-by-step explanation:

The total area is 2(L * H) + 2(W * H) or

2(20 * 10) + 2(15 * 10)

= 2*200 + 2*150 = 700 total sq ft.

Since one can covers 350, then 700/350 = 2 cans, BUT they want 2 coats so

double it (2*2=4).

$Hi!~I~am~beinggreat78,~and~I~will~help~you!$

Let's start by breaking down the problem.

This is how it should look. ↓

$60$ ÷ $20$ ⇒ $+ 3$ ⇒ $x * 5^2$

What does that x mean? x is just a substituted value for the first 2 equations.

Now, we can solve.

$60$ ÷ $20$ $= 3$

Add 3

$3 + 3 = 6$

Now, multiply 6 times 5 squared. What does 5 squared mean? 5 squared is just 5 times itself once. You most likely want to solve 5 squared before multiplying.

$5^2~or~5 * 5 = 25$

And now for the last step, multiply 25 times 6

$25 * 6 = 150$

With that information, the problem is solved! Your answer is 150

8 numbers have a sum of 90. Whats the average number?

ehidna [41]

Answer:

$\huge\boxed{11.25}$

Step-by-step explanation:

When finding the average of a set of numbers, we

A) Add up all the numbers
B) Divide that sum by the total number of numbers in the data set

Let's represent this with a formula, s being the sum of all numbers, n being the total number of numbers.

$\frac{s}{n}$

Since we already know the sum and we know how many numbers there are (8), we can substitute inside our expression $\frac{s}{n}$ to find the average.

$\frac{90}{8}$
$11.25$

Therefore, the average of all these numbers is 11.25.

Hope this helped!

PLEASEEE HELP MEEEE NO LINKSSS

Artemon [7]

Answer:

$\huge\boxed{(2,\ 3);\ (-1,\ 6)}$

Step-by-step explanation:

$f(x)=x^2-2x+3\to y=x^2-2x+3\\f(x)=-x+5\to y=-x+5\\\\\left\{\begin{array}{ccc}y=x^2-2x+3&(1)\\y=-x+5&(2)\end{array}\right$

substitute (1) to (2):

$x^2-2x+3=-x+5$ add x to both sides

$x^2-2x+x+3=-x+x+5$

$x^2-x+3=5$ subtract 5 from both sides

$x^2-x+3-5=5-5$

$x^2-x-2=0\\\\x^2+x-2x-2=0\\\\x(x+1)-2(x+1)=0\\\\(x+1)(x-2)=0\iff x+1=0\ \vee\ x-2=0\\\\\boxed{x=-1\ \vee\ x=2}$

substitute the values of x to (2):

$x=-1\\\\y=-(-1)+5=1+5=6\\\\\huge\boxed{(-1,\ 6)}\\\\x=2\\\\y=-2+5=3\\\\\huge\boxed{(2,\ 3)}$
