(2x+2) is the right answer.Shelly started driving her own car for Uber. she charges a flat fee of $5.00 and $0.50 for every kilometer Before plugging 32.50 into it, what would your equation look like?
Your answer
Answer:
The equation will be y=0.50x+5 before plugging 32.50
Step-by-step explanation:
Given that:
Flat fee charged by Shelly = $5.00
Per kilometer charges = $0.50
Let,
x be the number of kilometers driven.
y be the total amount earned.
y = 0.50x + 5
Hence,
The equation will be y=0.50x+5 before plugging 32.50

Sam needs a web designer. Designer A is offering her services for an initial $550 in addition to $120 per hour. Designer B is offering her services for an initial $660 in addition to $65 per hour. When will the two designers charge the same amount of money?
Answer: for 2 hours of web designing , they charge same amount.
Step-by-step explanation:
Let x = Number of hours.
Total charge = Initial fee + (Charge per hour x Number of hours )
For Designer A,
Total charge = 550 + 120x
For Designer B,
Total Charge = 660+65 x
When the two designers charge the same amount of money, then
550 + 120x = 660+65 x
⇒ 120x-65x= 660-550
⇒ 55x= 110
⇒ x = 2 [Divide both sides by 2]
So, for 2 hours of web designing , they charge same amount.

Grace uses a different way to divide 2.16 by 0.25 .She divides both the divisor and dividend by 0.01 to make an equivalent problem with a whole number divisor is her work correct ? Explain
Answer:
8.64. Her work is correct
Step-by-step explanation:
Given the expression to divide 2.16 by 0.25
Dividing both expressions to a whole number by dividing them by 0.01 is true as shown;
2.16/0.25 = (2.16/0.01)÷(0.25/0.01)
(2.16/0.01)÷(0.25/0.01) = 216/25
216/25 = 8.64
Hence her value is 8.64 making her work correct

what is the y- intercept of the line with the eqaution y=-2x+4
Answer:
(0,4)
Step-by-step explanation:
When you are finding the y-intercept, the x = 0
y = -2x + 4
y = -2(0) + 4
= 0 + 4
y = 4
Meaning y = (0,4)

use the coordinates of the labeled point to find a point-slope equation of the line
Answer:
B. y + 2 = -2(x - 4)
Step-by-step explanation:
First, find the slope (m) of the line using two points in the line, (3, 0) and (4, -2):
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-2 - 0}{4 - 3} = \frac{-2}{1} = -2 [/tex]
Slope (m) = -2.
Next, substitute (a, b) = (4, -2) and m = -2 into y - b = m(x - a)
Thus:
y - (-2) = -2(x - 4)
y + 2 = -2(x - 4)

Jason went to the Hamburger Shack twice last week.
On the first trip, he bought 3 hamburgers and 4 orders
of French fries for $7.10.
On the second trip, he bought 2 hamburgers and one
order of French fries for $3.40.
What is the cost of a hamburger??
Answer:
Cost of 1 hamburger = $1.3
Step-by-step explanation:
Assume;
Cost of 1 hamburger = a
Cost of 1 French fries = b
On first trip
3a + 4b = 7.10......eq1
On second trip
2a + b = 3.40....eq2
From eq2 x 4
8a + 4b = 13.6....eq3
From eq3 - eq1
5a = 6.5
a = 1.3
Cost of 1 hamburger = $1.3
The cost of a hamburger and an order of French pies is $1.3 and $0.8 respectively.
let
cost of hamburger = x
cost of French pies = y
The equation:
3x + 4y = 7.10 (1)
3x + 4y = 7.10 (1)2x + y = 3.40 (2)
multiply (2) by 4
8x + 4y = 13.6 (3)
3x + 4y = 7.10 (1)
subtract (3) from (1)
8x - 3x = 13.6 - 7.10
5x = 6.5
x = 6.5 / 5
x = 1.3
substitute x = 1.3 into (2)
2x + y = 3.40 (2)
2(1.3) + y = 3.40
2.6 + y = 3.40
y = 3.40 - 2.6
y = 0.8
Therefore, cost of a hamburger and an order of French pies is $1.3 and $0.8 respectively.

The Maxwell family goes out for dinner. The price for the
meal is $90. The sales tax on the meal is 7.25% and they
also want to leave an 18% tip. What is the total cost of the
meal?
Answer:
$113.90
Step-by-step explanation:
Find the cost of the meal with sales tax:
90 x 0.075 = 6.525
Add that to the original cost of the meal:
90 + 6.525 = 96.525
Find the cost of the tip:
96.525 x 0.18 = 17.3745
Add the tip to the meal price:
96.525 + 17.3745 = 113.8995

A cone is placed inside a cylinder as shown. The radius of the cone is half the radius of the cylinder. The height of the cone is equal to the radius of the cylinder. What is the volume of the cone in terms of the radius, r?
Step-by-step explanation:
Volume of Cone
= 1/3 * (Base Area) * (Height).
Since the radius of the cone is r/2, we have
Base Area = π(r/2)² = πr²/4.
Also the height of the cone is r.
Hence Volume of Cone
= 1/3 * (πr²/4) * (r)
= πr³/12. (C)

4.05 x 0.8 =
3,240
32.4
3.24
324
Answer:
3.24!
Step-by-step explanation:
Option c is correct, 4.05 multiplied by 0.8 is equal to 3.24.
To calculate 4.05 multiplied by 0.8, you multiply the two numbers together.
First, you can ignore the decimal points and multiply 405 by 8, which equals 3,240.
Next, you count the total number of decimal places in the original numbers.
The decimal point is present in both 4.05 and 0.8, so there are two decimal places in total.
To get the final result, you need to place the decimal point in the product so that it has two decimal places.
Starting from the right side of the product, you place the decimal point two places to the left, resulting in 3.24.
Therefore, 4.05 multiplied by 0.8 is equal to 3.24.
