Answer:

Age Group Number of People 18–24 80 25–31 120 32–38 40 39–45 20

The data in each bar is how many people in that group.

So 18-24 has 80 people

25-31 has 120 people

32 -38 has 40 people

39-45 has 20 people

The Northwest Football team drove 25 mi of their 3-hour trip to San Angelo for their game. They used 1.7 gal of gasoline. What a

gayaneshka [121]

Some of the rates that can be formed are; Speed = 8.333 mph

Number of miles covered per gallon of gasoline used = 14.706 mpg

The number of gallons used per hour = 0.567 gallons per hour

<h3>How to use units conversion?</h3>

We are told that the Northwest Football team drove 25 miles.

Now, the time that this team took was 3 hours.

Thus, one rate that can be formed is the speed in mi/hr. Thus;

Speed = 25/3 = 8.333 mph

Another rate that can be found is the number of miles covered per gallon of gasoline used. This gives us;

25/1.7 = 14.706 mpg

Another rate that can be gotten is the number of gallons used per hour;

= 1.7/3 = 0.567 gallons per hour

Aleks04 [339]

The answer is the third one (C?) because if you started at 0, you are going below it since you are losing yards, causing you to have less and less yards. Adding two negatives gives you a lesser amount.

Indicate the equation of the given line in standard form.

Lorico [155]

We have that
<span>triangle ABC
where
A(-5, 5), B(1, 1), and C(3, 4) are the vertices

using a graph tool
see the attached figure

the hypotenuse is the segment AC

find the equation of the line AC
</span>A(-5, 5) C(3, 4)
<span>
step 1
find the slope m
m=(y2-y1)/(x2-x1)-----> m=</span>(4-5)/(3+5)-----> m=-1/8

step 2
with C(3,4) and m=-1/8
find the equation of a line
y-y1=m*(x-x1)-----> y-4=(-1/8)*(x-3)----> y=(-1/8)*x+(3/8)+4
y=(-1/8)*x+(3/8)+4----> multiply by 8----> 8y=-x+3+32
8y=-x+35
the standard form is Ax+By=C
so
x+8y=35
A=1
B=8
C=35

the answer is
x+8y=35
