The ratio of the side lengths triangle is 7:24:29 and it’s perimeter is 180 m. What are the side lengths of the triangle? Select

kakasveta [241]

Answer: Only 21:72:87

Explanation: We know that the side lengths are not simply 7, 24, and 29, as the sum of these is only 60.

Therefore, we need to find the scale factor they were multiplied by to have side lengths with a sum of 180.

We can use 7x+24x+29x=180.

This becomes 60x=180 and the scale factor is x=3.

7*3=21, 24*3=72, and 29*3=87.

A survey was conducted about the colors of shoes that people

Answer:

Option B) 0.797

Step-by-step explanation:

we know that

The probability of an event is the ratio of the size of the event space to the size of the sample space.

The size of the sample space is the total number of possible outcomes

The event space is the number of outcomes in the event you are interested in.

so

Let

x------> size of the event space

y-----> size of the sample space

so

$P=\frac{x}{y}$

step 1

Find the probability that a randomly selected person was female

In this problem we have

$x=33$ ----> total females

$y=31+33=64$ ---> total males plus total females

substitute

$P=\frac{33}{64}$

step 2

Find the probability that a randomly selected person was was wearing brown shoes

In this problem we have

$x=18$ ----> total brown shoes

$y=64$ ---> total shoes

substitute

$P=\frac{18}{64}$

step 3

Find the probability that a randomly selected person was either female or was wearing brown shoes

Adds the probabilities

$P=\frac{33}{64}+\frac{18}{64}=\frac{51}{64}=0.797$

Consider the parametric equations below.

maksim [4K]

Solve the second equation for $t$ , then substitute it into the first equation.

$y = t + 2 \implies t = y-2$

$x = t^2 - 3 \implies \boxed{x = (y-2)^2 - 3}$
