The rental rate for a cement mixer has a flat rate of $40 plus $20 for each day of the rental. The graph shows points representing the total cost of the rental. Which linear equation, in slope-intercept form, that models the total cost of the rental over time? y = 20x +40 y = x + 50 y = 50x + 25 y = 25x y = 75x
Answer:
Step-by-step explanation:
y= 20x+40
y- is the cost of rental
x-number of days
20 is the slope
40-flat rate and the y-intercept is at (0,40)
At 9:00 a.m., the wind speed at Harbor Bay was recorded. After that, the wind speed was recorded every hour. Each measurement showed an increase in wind speed of 3 miles per hour. The strongest wind was recorded at 4:00 p.m., and measured 52 miles per hour. After that, the wind speeds started to decrease. How windy was it when the experiment began?
Answer:
The wind speed was 31 miles per hour when the experiment began.
Step-by-step explanation:
Linear Dependency
The wind speed is known to increase at a rate of 3 miles per hour every hour.
From 9:00 a.m. to 4:00 p.m. there are 7 hours.
Thus, the speed increased by 7 * 3 = 21 miles per hour during that period of time.
Assuming the wind increased linearly, and its speed was measured at 52 miles per hour at 4:00 p.m., then the initial speed at 9:00 a.m. is calculated by subtracting:
52 miles / hour - 21 miles / hour = 31 miles / hour
The wind speed was 31 miles per hour when the experiment began.
Answer:
The wind speed was 31 miles per hour when the experiment began.

EXPENSES: Camille has no more than $50.00 to spend each week for lunch and bus fare. Lunch costs $3.00 each day, and bus fare is $1.75 each ride. Write an inequality for this situation. Can Camille buy lunch 7 times and ride the bus 14 times in one week????
Answer:
Inequality: [tex]3.00 L + 1.75B \leq 50[/tex]
She can afford to buy the lunch and bus rides
Step-by-step explanation:
Given
[tex]Maximum\ Amount = \$50.00[/tex]
[tex]Lunch = \$3.00[/tex] daily
[tex]Bus\ Fare = \$1.75[/tex] daily
Solving (a) The inequality
Let bus ride be represented with B and Lunch be represented with L
If 1 bus ride costs $1.75, then
B bus ride would cost $1.75 * B
If 1 lunch costs $3.00, then
L lunch would cost $3.00 * L
Total Spending is then the sum of the above expression i.e.
$3.00 * L + $1.75 * B
The question says Camille can not spend more than $50.00.
This is represented by less than or equal to.
So, the expression is:
[tex]3.00 * L + 1.75 * B \leq 50[/tex]
[tex]3.00 L + 1.75B \leq 50[/tex]
Solving (b): Can she afford 7 lunch and 14 bus ride?
To do this, we simply substitute 7 for L and 14 for B
[tex]3.00 * 7 + 1.75 * 14 \leq 50[/tex]
[tex]21 + 24.5 \leq 50[/tex]
[tex]45.5 \leq 50[/tex]
The above inequality is true.
Hence, she can afford to buy the lunch and bus rides

2. Suppose there are 6 million people in New York City that walk an average of 2.5 miles per day. If we add up all the miles walked by these 6 million how many times around the Earth would these walkers have gone? Assume the distance around the Earth is 2.5 * 10 ^ 4 miles. Write your result in scientific notation.
Answer:
600 timesStep-by-step explanation:
GivenNumber of people:
6 million = 6*10^6Distance to walk:
2.5 miles per day per personDistance around the Earth
2.5*10^4SolutionTotal distance walked:
6*10^6*2.5 = 15*10^6The ratio of total distance to the distance around the Earth:
15*10^6 / 2.5*10^4 = 6*10^2 = 600 timesNumber of people:
6 million = [tex]6[/tex] × [tex]10^{6}[/tex]
Distance to walk:
2.5 miles every day per person
Distance around the Earth
[tex]2.5[/tex] ×[tex]10^{4}[/tex]
Total distance walked:
[tex]6[/tex] × [tex]10^{6}[/tex] × [tex]2.5[/tex] [tex]= 15[/tex] × [tex]10^{6}[/tex]
The ratio of total distance to the distance around the Earth:
[tex]15[/tex] × [tex]10^{6}[/tex] / [tex]2.5[/tex] × [tex]10^{4}[/tex] = [tex]6[/tex] × [tex]10^{2}[/tex] = [tex]600[/tex]
how indentify a slope and y intercept
Answer:
Slope is rise over run so you pick a point on the line see how far it goes to the right and put that over how far it goes up
y- intercept is the point at which the line crosses the y axis

Answer:
35 + .80x > 50
Step-by-step explanation:
You have the original price, which is 35 dollars. Then you have per page, it's 80 cents. You don't know how many pages there are, so you put x. Then it has to be LESS than 50, so you put > 50
4x-2=x+13
Solve for X
Show all steps
Answer:
x=5
Step-by-step explanation:
isolate the x on one side of the equal sign so move the 2 over by adding 2
4x=x+15 ( add 2 to both sides )
then move the x over
3x=15 ( subtract x from both sides )
then divide by 3
x=5
Answer: Hope it helps, have a nice day :)
x=5
Step-by-step explanation:
So you can only have x on one side, so first you move an x to the other side of the equal sign.
so, 4x-2=x+13, you can move either x, but I'm moving x instead of 4x
-x -x
Your new equation is 3x-2=13, because the x's cancel out
Then you add 2 on both sides 3x-2=13
+2 +2
___________
3x=15
then you divide by 3 on both sides
3x divided by three leaves x by itself, and 15 divided by three is 5.
3x=15
3 3
x=5

In a polar coordinate system, the midpoint of the line segment whose endpoints are $\left( 8, \frac{5 \pi}{12} \right)$ and $\left( 8, -\frac{3 \pi}{12} \right)$ is the point $(r, \theta).$ Enter $(r, \theta),$ where $r > 0$ and $0 \le \theta < 2 \pi.$
Answer:
Step-by-step explanation:
Given the coordinate points (8, 5π/12) and (-3, π/12)
The midpoint is expressed using the formula
M(X,Y) = {(x1+x2)/2, (,y1+y2)/2}
X = x1+x2/2
X = 8-3/2
X = 5/2
Y = y1+y2/2
Y = (5π/12+π/12)/2
Y = (6π/12)/2
Y = 6π/24
Y = π/4
Hence the required coordinate is at(2.5, π/4)
