You divide 4 by 20 to get 5 then multiply by 32 to get 160 so Margie drive 160 mles on $20 worth of gas

What is the 100th term in the following arithmetic number pattern: 2,7,12

ivanzaharov [21]

So the change in between terms is 5 so you would put 5x, then for the first term, which is 2, 5*1(x)(because it's first term) then the difference between 5-2(because it's the 2nd term) So you would plug 100 in for x so 5(100)-3=497. Hope this helped!

One side of a triangle is 3 times longer than the shortest side and the third side is 4 centimeters longer than the shortest sid

givi [52]

Answer:

First side is: 12cm

Second side is: 36cm

Third side is: 16cm

Step-by-step explanation:

Let x represent the shorter side

Then 3x represents the second side, and

x + 4 represents the third side.

Perimeter of three sides:

P = x + 3x + (x + 4)

Perimeter is 64, so

64 = x + 3x + (x + 4)

64 = 5x + 4

60 = 5x

12 = x

First side is x: 12cm

Second side is 3x: 3(12) = 36cm

Third side is x + 4: 12 + 4 = 16cm

An internet cafe charges a fixed amount per minute to use the internet. The cost of using the internet in dollars is, y = 3/4x.

Vinil7 [7]

ANSWER

8 minutes

EXPLANATION

We know that the cost of using the internet in dollars is given by,

$y=\frac{3}{4}x$

Where x is the number of minutes spent on the internet.

In this problem, we have to find how many minutes will 6 dollars buy. In other words, we have to find x for y = 6. To solve the given equation for x, we have to multiply both sides by 4,

$\begin{gathered} 4y=4\cdot\frac{3}{4}x \\ \\ 4y=3x \end{gathered}$

And divide both sides by 3,

$\begin{gathered} \frac{4y}{3}=\frac{3x}{3} \\ \\ \frac{4y}{3}=x \end{gathered}$

So, for y = 6, x is,

$x=\frac{4\cdot6}{3}=\frac{24}{3}=8$

Hence, $6 will buy 8 minutes.

Help help help! Lateral area means total surface area I believe!<br> Thanks!

pentagon [3]

$\qquad\qquad\huge\underline{{\sf Answer}}☂$

Let's solve ~

$\qquad \sf \dashrightarrow \:lateral \: surface \: area = \pi rl$

$\qquad \sf \dashrightarrow \:la = \pi12 \times 15$

$\qquad \sf \dashrightarrow \:la =180 \pi$

Therefore, the lateral surface area of cone = 180 pi in²
