Answer
36/9= 4
Step-by-step explanation:
This is a fraction equal to
36 gallons ÷ 9 minutes
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 9
36 gallons ÷ 9
9 minutes ÷ 9
=
4 gallons
1 minute
=
4 gallons
minute
= 4 gallons per minute
Alright.
So let's say the number of adults is x.
Therefore, the number of boys is 7x + 1.
And then the total amount of girls is 3.5x + 0.5
So then:
x + 7x + 1 + 3.5x + 0.5 = 82
11.5x + 1.5 = 82
11.5x = 80.5
x = 7
So now we can figure out the number of male and female students.
Male students = 7x + 1
7*7 + 1
49 + 1
50
Male Students = 50
Female students = half of 50
50/2 = 25
Female Students = 25
Answer:
3,131,313
Step-by-step explanation:
Let X represent the number of cases with diabetes in 1973.
An increase of 396% in diabetes cases in 1973 would be;
12.4 million = 396/100 × X
12.4 million = 396X/100
Cross multiply
12.4 million × 100 = 396X
X = [(12.4 million × 100) / 396]
X = 3,131,313
Therefore, the number of diabetes cases in 1973 is 3,131,313 cases
Given:
To find:
Solution:
Substitute .
Subtract 26° from both sides.
Divide by 2 on both sides, we get
Therefore, m∠1 = 35°.
Answer:
Angle of elevation of the airplane = 17.46 degrees
Step-by-step explanation:
From the picture attached,
An airplane is flying at an altitude of 1500 ft at point A.
Runway starts from point B from which distance of the airplane is 5000 ft.
Now we apply sine rule in the given triangle ABC to measure the angle θ.
sinθ = 
sinθ = 
= 
degrees
