And hey if you know that 20/100 is 13, then how do you find the amount of 80/100?

1 answer:

7 0

How is 20/100 = 13...

Anyways, look at the two fractions.

20/100 and 80/100

Notice how 20 times 4 equals 80?

So maybe, 13 * 4 = 52.

Triangle ABC has vertices at A(−1 , 2), B(4, 2), and C(3, −1). Classify the triangle according to the side lengths.

Orlov [11]

Answer:

B) Isosceles

Step-by-step explanation:

The given triangle has vertices at A(-1,2), B(4,2) and C(3,-1).

We must first determine the length of the sides of the triangle, before we can classify it.

We apply the distance formula to find length of the sides.

$|AB|=\sqrt{(4--1)^2+(2-2)^2}$

$\Rightarrow |AB|=\sqrt{(4+1)^2+(2-2)^2}$

$\Rightarrow |AB|=\sqrt{5^2+(0)^2}$

$\Rightarrow |AB|=\sqrt{25}$

$\Rightarrow |AB|=5 units$ .

The length of side BC

$|BC|=\sqrt{(3-4)^2+(-1-2)^2}$

$\Rightarrow |BC|=\sqrt{(-1)^2+(-3)^2}$

$\Rightarrow |BC|=\sqrt{1+9}$

$\Rightarrow |BC|=\sqrt{10}$

The length of side AC

$|AC|=\sqrt{(3--1)^2+(-1-2)^2}$

We simplify to obtain;

$|AC|=\sqrt{(3+1)^2+(-3)^2}$

$\Rightarrow |AC|=\sqrt{(4)^2+(-3)^2}$

$|AC|=\sqrt{16+9}$

$|AC|=\sqrt{25}$

$|AC|=5\:units$

Since $|AC|=5\:units=|AB|$ , the given triangle is an isosceles triangle.

It costs $36.76 for 3 tickets to visit the science center. It costs $51 for 4 tickets to visit the zoo. Which attraction will co

NeX [460]

Answer:

The zoo will cost more money for a group of 12 students to visit.

Step-by-step explanation:

First, you have to divide the costs by the amount of tickets to find out how much you would have to pay for one ticket.

Science Center: $36.76 ÷ 3 = $12.25

Zoo: $51 ÷ 4 = $12.75

Then, the cost for one ticket should be multiplied by 12, the group of students wanting to visit.

Science Center: $12.25 x 12 = $147.04

Zoo: $12.75 x 12 = $153

Comparing the prices, you will see that the zoo will cost $5.96 more dollars than the science center.
