John used 5/6 of a tank of gas each day while traveling to the Super Bowl. He drove for 9 days in a row . How much gas did he use in all.
Answer:
7 1/2 tanks of gas
Step-by-step explanation:
5/6 • 9
= 45/6
Simplify.
7 1/2 tanks of gas in all
Answer:
7 1/2
Step-by-step explanation:
5 times 9 is 45. 45/6 simplified is 7 3/6 or 7 1/2

Suppose a movie rental company charges $9.99 per month plus $1.25 for every movie rented.
A. Write a function rule that represents the relationship between the number of movies rented in a month and
the rental charge for that month.
b.
Write an equation that you could solve to find how many movies you rented if the total rental charge for one
month was $23.74.
C.
Solve this equation using a table.
Answer:
9.99+ 1.25x. X represents the every movies rented. I think my answer matches b, I am not sure.

A tank that holds up 10 gallons. when its active, a drain empties water from the tank at a constant rate, when Jada first see the tank, it contains 7 gallons of water. three minute later the tank contains five gallons of water.
At what constant/rate is the amount of water changing in the tank?
Answer:
-2/3 gallon/minute
Step-by-step explanation:
In three minutes the water volume has decreased by 2 gallons (7 less 5 is 2). The unit rate of decrease of the amount of water in the tank is thus:
- 2 gallons
------------------- = -2/3 gallon/minute

A colony of 50 bacteria double in size every 30 minutes. What will the population be 120 mintues from now?
Answer:
800 bacteria
Step-by-step explanation:
Over here, we have exponential growth.
So we have 50 bacteria
Every 30 minutes, it doubles in size
In 120 minutes, there are four 30 minutes.
So you do 50 * 2 * 2 * 2 * 2
Do that out and you get 800
Let me know if you have any questions
SOMEONE PLEASE HELP AND EXPLAIN HOW TO DO THIS!!
Answer:
Your answer should be B or D.
Step-by-step explanation:
You have to find x. If the first side is 60 degrees and the other is 70 degrees, that means that the last side should be similar to that. yo can use a protractor if you have one, or you can estimate. now for the equation part. once you have the degree for the angle, you need to use the numbers to multiply to get the number. Multiply 8 by all of the numbers. Since the angle is acute, the answer has to be less than 90.
A school rewards students for good work by giving them merit points.
James has x merit points.
Sarah has four times as many merit points than James.
Robert has 31 fewer merit points than James.
Each merit point is worth 3 pence.

Which of these describes the equation –18x + 9y = –416?
A
The equation is not linear because it has 2 variables, not 1.
B
The equation is not linear because it is not in the form y = mx + b.
С
The equation is linear because it has variables with exponents of 0.
D
The equation is linear because it can be rewritten in the form y = mx + b.
Answer:
We conclude the equation is linear because it can be rewritten in the form [tex]y = mx + b[/tex].
Hence, option D is correct.
Step-by-step explanation:
The slope-intercept form of the line or linear equation
[tex]y = mx+b[/tex]
where
[tex]m[/tex] is the slope[tex]b[/tex] is the y-intercept
Important Tip:
The graph of a linear equation is always a straight line.
Convert the given equation in the slope-intercept form
[tex]18x + 9y = -416[/tex]
subtract 18x from both sides
[tex]18x+9y-18x = - 18x-416[/tex]
simplify
[tex]9y = -18x - 416[/tex]
divide both sides by 9
[tex]y=-2x-\frac{416}{9}[/tex]
Now, comparing the equation [tex]y=-2x-\frac{416}{9}[/tex] with a slop-intercept form of linear equation
The slope m = -2The y-intercept b = -416/9Therefore, we conclude the equation is linear because it can be rewritten in the form [tex]y = mx + b[/tex].
From the attached graph, is also clear that the graph of the equation [tex]y=-2x-\frac{416}{9}[/tex] is a straight line.
Hence, option D is correct.

Can someone please tell me the degree measure of angles 1,2 3 and 4?
It’ll help even more if you explain.
Answer:
angle 1 is 42
angle 2 is 138
angle 3 is also 42
Step-by-step explanation:
for angle 1, I don't remember what the exact rule was but basically since they are opposite of each other they are equal
for angle 2 all you have to do is subtract 42 from 180 because line n is at an angle of 180 and line m simply splits it into two pieces
for angle 3, I dont remember what the exact rule is or hot to explain it well but it is also 42
Alejandro decided on purchasing a $160,000 home. At closing he brought a check for $4940. The closing costs were as follows:

what is 512.3 divided by 10
Answer:
51.23
Step-by-step explanation:
Hi !
So basically all you need to do with an equation like this move the decimal.
And the direction you move it depends on the value of the largest digit as well as if it is larger or smaller than 0.
So lets look at 10 and make it 10.0 so its a decimal and make things a bit easier.
So 10.0 is just one digit moved in the decimal world. (100.0 would be 2, 1000.0 would be 3, and so on.)
And 10.0 is greater than 0.
Greater than 0 = Move decimal left
Less than 0 = Move decimal right
So now we know to move one space to the left.
512.3
>
One to the left
>
51.23
And its that easy, that is your answer.

F(x)=bx^2+32 For the function f defined above, b is a constant and f(2)=40. What is the value of f(-2)?
Answer:
f(-2) = 0
Step-by-step explanation:
Given that:
f(x) = bx^2 + 32
f(2) = b(2)^2 + 32
f(2) = 4b + 32
f(2) = 4b = -32
f(2) = b = -32/4
f(2) = b = -8
Thus;
f(-2) = -8(-2)^2 + 32
f(-2) = -8(4) + 32
f(-2) = -32 + 32
f(-2) = 0

Hope this helps!!!
anyone think they could help me with this ?
Answer:
10
Step-by-step explanation:
As we can see in hint through it we can identify that it is right angled triangle so here
AB = 6
FE = BC ( being corresponding sides of congruent triangle)
BC = 8
Now In triangle ABC
perpendicular (p) = 6
base (b) = 8
hypotenuse (h) = ?
By using Pythagoras theorem we get
h = √ p² + b²
= √ 6² + 8²
= √ 100
= 10
So Now
AC = h = 10
Hope it will help :)

in the park.
Elevation (m)
-32.6
24.7
-8.3
19.1
- 8.4
a. What is the mean of the elevations? Show your work.
Answer:
It is the quarter fourth of the elevation
Step-by-step explanation:
The meaning of elevations is a high above meaning level
Answer:
Step-by-step explanation:
The mean is just the arithmetic average, the sum of numbers divided the number of terms.
m=(-32.6+24.7-8.3+19.1-8.4)/5
m=-5.5/5
m=-1.1
