Number of boy students on bus = 5
Total number of students on the bus = 8
Fraction of students are boys = 5 / 8
1. By definition, the sum of the Suplementary angles is 180° and the sum of the Complementary angles is 90°. Keeping this on mind, you have:
90-x (The complement of the angle)
180-x (The sumplement of the angle)
"x" is the angle that you want to calculate.
2. Then, you have:
3(90-x)+30=180-x
(270-3x)+30=180-x
300-3x=180-x
300-180=-x+3x
120=2x
120/2=x
x=60°

What is the measure of the angle?</span>
The answer is: The measure of the angle is 60°.
Answer:
<u>Question 1:</u>
5 pints per hour
<u>Question 2:</u>
480 tons per day
<u>Question 3:</u>
12 miles per gallon of gasoline
<u />
Step-by-step explanation:
<u>Question 1:</u>
<h2><em>In the morning;</em></h2>
A farm worker packed 3 pints of grapes every 4 minutes.
1 minute =
hours
Packing rate in pints per hour = 3 pints ÷
hours = 45 pints per hour
<h2><em>In the afternoon;</em></h2>
She packed 2 pints of grapes every 3 minutes.
Packing rate in pints per hour = 2 pints ÷
hours = 40 pints per hour.
The difference between her morning and afternoon packing rates (in pints per hour) = 45 pints per hour - 40 pints per hour = 5 pints per hour
<u>Question 2:</u>
A recycling plant processes an average of
tons of glass each minute.
1 hour = 60 minutes
The number of tons of glass processed in 1 hour is:
× 60 = 20 tons of glass in 1 hour.
1 day = 24 hours
Number of tons of glass processed in a day = 20 tons × 24 = 480 tons
<u>Question 3:</u>
A vehicle uses 1
gallons of gasoline to travel 13
miles.
Per 1 gallon of gasoline the vehicle will travel:
1 × 13
÷ 1
= 12 miles
Answer:
5 / (x+4) x ≠2 x≠-4
Step-by-step explanation:
5(x-2)/(x-2)(x+4)
The denominator cannot be zero so x ≠2 x≠-4
Cancel like terms in the numerator and denominator
5 / (x+4) x ≠2 x≠-4
