In △ABC, m∠A=32°, m∠B=25°, and a=18. Find c to the nearest tenth.
olga55 [171]

Trig!!!-

We can use trig function to find the answer-

we know that tangent is opp/adjacent

Thus c=180-32-25=123 degrees and

tan 123=18/c

This c=34.7539008597 since it is tan 123=0.51792747158 and we use algebra to solve for c and it is 18/tan 123=c and then c=34.8 when we round to the nearest tenth

One pipe fills a storage pool in 20 hours, another pipe fills the same pool in 15 hours.
erica [24]
X=time  of the third person it would take to fill the pool 
We can suggest this equation:
6[(1/20) + (1/15) +(1/x)]=1
6[(3x+4x+60)/60x]=1
(7x+60)/10x=1
7x+60=10x
7x-10x=-60
-3x=-60
x=-60/-3
x=20

Answer: the third person alone would fill the pool in 20 hours .

Yesterday a car rental agency rented 4 vehicles, of which 2 were pickup trucks. what is the experimental probability that the fi
irina [24]

Using it's concept, it is found that the experimental probability that the first vehicle rented today will be a pickup truck is of 0.5 = 50%.

<h3>What is a probability?</h3>

A probability is given by the<u> number of desired outcomes divided by the number of total outcomes</u>. For an experimental probability, these number of outcomes are taken from previous trials.

In this problem, we have that out of 4 vehicles, 2 are pickup trucks, hence the experimental probability is given by:

p = 2/4 = 1/2 = 0.5.

The expression to find the perimeter of a rectangle is 2(length + width). What is the perimeter, in units, of a rectangle of len
Allisa [31]
First you plug in the data to the formula. So it will be 2(1/3+1/2). You then want to add the fractions together but must first find the common denominator which will be 6. So it is 2(2/6+3/6). The fractions then add up to be 5/6. So all you have to do is multiply it by 2 to get 5/3 which simplifies to 1 2/3 so it is D.
