A construction crew built 514 miles of road in 412 days. What is the unit rate in miles per day? Write your answer as a fraction or a mixed number in simplest form.
Answer:
[tex]R=\dfrac{257}{206}\ \text{miles/day}[/tex]
Step-by-step explanation:
Given that,
Distance, d = 514 miles
Time, t = 412 days
We need to find the unit rate in miles per day. Its rate is given calculated by dividing distance and time as follows :
[tex]R=\dfrac{514\ \text{miles}}{412\ \text{days}}\\\\R=\dfrac{257}{206}\ \text{miles/day}[/tex]
So, the unit rate is [tex]\dfrac{257}{206}\ \text{miles/day}[/tex].

Based on the graph, which inequality is correct for a number that is to the left of -4?
a
−7 > −4
b
−6 −4
d
−4 < −9
Answer:
From the graph, it is clear that the left of -4 will always be lesser than the -4.
and -6 is the left of -4. so -6 will be lesser than -4.
so, [tex]-6 < -4[/tex] is the correct option.
Therefore, the option 'd' is the correct answer.
Step-by-step explanation:
Let us analyze all the given inequalities
Given the inequality
[tex]-7\:>-4[/tex]
As -7 can not be greater than -4, so [tex]-7\:>-4[/tex] is false.
Given the inequality
[tex]-8>-4[/tex]
As -8 can not be greater than -4, so [tex]-8>-4[/tex] is false.
Given the inequality
[tex]-4 < -9[/tex]
As -4 can not be lesser than -9, so [tex]-4 < -9[/tex] is false.
Given the inequality
[tex]-6 < -4[/tex]
As -4 is always greater than -6, so [tex]-6 < -4[/tex] will be true.
From the graph, it is clear that the left of -4 will always be lesser than the -4.
and -6 is the left of -4. so -6 will be lesser than -4.
so, [tex]-6 < -4[/tex] is the correct option.
Therefore, the option 'd' is the correct answer.

The Drama Club held a car wash to raise money. The equation y = 15x represents the amount of money y club members made for washing x cars. Identify the constant of proportionality.
Answer:
15
Step-by-step explanation:
Given that:
y = 15x
y = amount of money made by club members made for washing cars
x = number of cars washed
From the equation given ;
Amount made is directly proportional the number of cars washed
Mathematically,
y α x
y = kx
Where k = constant of proportionality
Comparing the given equation with
y = kx
y = 15x
k = 15 = constant of proportionality

Jerry and Jo are making brownies for the bake sale.
Each pan of brownies will be cut into 18 rows with 12 brownies per row.
They plan to make 12 pans of brownies.
Choose Yes or No to tell if the equation shows the number of brownies they will make.
(12 x 18) ~ 12 = b
18 * (2 x 12) = b
18 x 12 = b
12 x (12 * 18) = b
Answer:
Yes
12 * (12 * 18) = b will give the total number of brownies to be made
Step-by-step explanation:
Here, we want to select which of the equations will give the number of brownies to be made
The total number of brownies is b
For each pan, we have 18 rows , with 12 per row
So the total number of brownies per pan is 12 * 18
Since they are making 12, the total number of brownies b will be;
12 * (12 * 18) = b
PLEASE HELP!! Which describes the graph of y = (x + 7)^2 - 9?

B. Vertex at (7, 9)
C. Vertex at (7, -9)
D. Vertex at (-7, -9)
I need to get this right so I can bring my grades up so please help!
Answer:
The answer is D. Vertex at (-7,-9).
Step-by-step explanation:
The equation is in vertex form, so you take the opposite of x and the constant stays the same. So, the opposite of 7 is -7 and -9 stays the same.

Someone help
Answer: m∠2 =60
60=4x+12
subtract 12 from both sides
60-12=4x+12-12
60-12=4x
48=4x
divide both sides by 4
48÷4=4x÷4
48÷4=x
x=12
Plug it into the equation
4(12)+12=
48+12=
m∠2 =60
another proof is that they are congruent

Mrs. Wally cut a 21 foot long ribbon into four equal lengths. How many feet long was each length of ribbon
the answer is:
Each equal length of ribbon is 5.25 ft
Step-by-step explanation:
21 divided by 4 is 5.25
To find the number of distributed quantities division operator is used. Each length of ribbon was 5.25 foot long.
What is division ?Division is a mathematical operation used to divide a number into equal parts. When a number is divided by another number, a quotient and remainder is obtained.
Given length of ribbon = 21 foot
Number of parts it has to be divided = 4.
So, to get the length of each part divide the total length by 4.
Thus, the length of each part is 21/4 = 5.25 foot.
Hence, the length Mrs. Wally' s each ribbon is 5.25 foot.
