Answer:

aₙ = a₁ + (n-1)d

where:

aₙ = nth term

a₁ = first term

d = common difference

A playground is shaped like a rectangle with a width 5 times it’s length. What is the simplified expression for the distance bet

Bad White [126]

Width: W
length: L = 5W

Use the Pyth. Theorem to find the length of the diagonal:

|D| = sqrt(W^2 + [5W]^2) = sqrt(W^2 + 25W^2) = sqrt(26W^2), or

Wsqrt(26) (ans.)

A 6-pack of capri-Suns costs $8.80 .How much would a 24-pack cost if the costs are proportional

andrew11 [14]

Now, in a 6-pack, there are 6 bottles, 6-pack.

in a 24-pack, there are 24 bottles, 24-pack.

so, if 6 bottles, cost 8.80, how much will it be for 24 bottles then?

$\bf \begin{array}{ccll}
bottles&price\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
6&8.80\\
24&p
\end{array}\implies \cfrac{6}{24}=\cfrac{8.80}{p}\implies p=\cfrac{24\cdot 8.80}{6}$

Drag steps in the given order to evaluate this expression. <br><br> (4)(−3)−5−3(−6)

never [62]

Answer:

Step-by-step explanation:

using PEDMAS(parentheses, exponents, division, multiply, addition, subtraction) to solve the problem

First we multiply (4)(-3)

(4)(−3)−5−3(−6)

Then multiply -3(-6)

(-12)-5-3(-6)

=-12-5+18

subtract 12-5

-12-5+18

=-17+18

Adding -17+18 gives us 1.

Therefore, (4)(−3)−5−3(−6) is 1.
