LIGHTING Kyle is buying strands of outdoor lights for his luau. The total cost of the strands can be modeled by the function f(c) = 8.97c. He received an email with a coupon code to receive $5 off his online purchase. A. Write a function g(c) that represents the cost of purchasing strands of lights with the $5 discount. B. Find the cost of purchasing 6 strands of lights before and after the discount. How about this one anyone
Answer:
Step-by-step explanation:
A. Function before discount:
f(c)= 8.97c
This means that cost per strand of outdoor light is $8.97 and c is number of strands of outdoor light bought. Therefore to model the function g(c) after he has received a $5 discount on his purchase(total purchase)
g(c)=8.97c-5
B. cost of 6 strands of light before discount
f(c)= 8.97×6= $53.82
cost of 6 strands of light after discount
f(c)=8.97×6-5= $48.82
Consider the enlargement of the triangle.
A small triangle has a base of 1.7 feet and height of 9.3 feet. A larger triangle has a base of 3.5 feet and height of x feet.
Not drawn to scale
Rounded to the nearest tenth, what is the value of x?
15.8 feet
19.1 feet
23.3 feet
32.6 feet
Answer:B 19.1 feet
Step-by-step explanation:
The value of the x is 19.1 feet.
What is ratio?"It is an ordered pair of numbers a and b, written [tex]\frac{a}{b}[/tex] where b does not equal 0."
What is proportion?"When two ratios are equal then they are said to be in proportion."
For given question,
A small triangle has a base of 1.7 feet and height of 9.3 feet.
A larger triangle has a base of 3.5 feet and height of x feet.
Since it is the enlargement of the triangle, the sides of both the triangle must be in proportion.
[tex]\Rightarrow \frac{1.7}{3.5}= \frac{9.3}{x}\\\\\ \Rightarrow 1.7\times x=3.5\times 9.3\\\\ \Rightarrow 1.7\times x=32.55\\\\ \Rightarrow x=19.14[/tex]
Therefore, the value of the x is 19.1 feet.

Kristopher has a coupon for $10 off any item at his favorite electronics shop. If he plans to use the coupon to purchase and item that costs $80, by what percentage will the price be decreased before tax?
Answer:
12.5%
Step-by-step explanation:
Kristopher has a coupon for $10 off any item at his favorite electronics shop. If he plans to use the coupon to purchase and item that costs $80, by what percentage will the price be decreased before tax?
The formula for Percentage Decrease =
Decrease in price/ Initial price × 100
Decrease in price = $10
Initial price = $80
Hence:
$10/$80 × 100
= 12.5%
Hence, the percentage the price will be decreased by before tax is 12.5%
In the figure above, rectangle V'W'X'Y' is a dilation of rectangle VWXY. What is the scale factor of the dilation?
A. 0.25
B. 2
C. 343 fourths
D. 14
Answer:
D. [tex] \frac{1}{4} [/tex]
Step-by-step explanation:
Given that rectangle V'W'X'Y' is a dilation of rectangle VWXY, this means that the dimensions of rectangle VWXY was reduced by to get the dimensions of V'W'X'Y'.
Therefore, the ratio of any segment of V'W'X'Y', to a corresponding segment of VWXY would be equal to the scale factor.
W'X' = 5
WX = 20
Therefore:
Scale factor = [tex] \frac{5}{20} = \frac{1}{4} [/tex].
A scale factor that is a fraction tells us that the original figure reduced in size resulting into another new figure whose sides are of proportional lengths to the original figure.
In other words, the original figure was compressed go form a new figure.
Sam and Taylor own and operate a car wash service. Sam cleans the interior of each car and Taylor cleans the exterior. The time it takes Sam to finish the interior has a mean of 20 minutes with a standard deviation of 6.4 minutes. The time it takes Taylor to finish the exterior has a mean of 18 minutes with a standard deviation of 4.8 minutes. Both of their finishing times are approximately normally distributed.
Suppose we select a car at random, and define the random variable D as the difference between their finishing times. We can assume that their times are independent.
Find the probability that they finish within 10minutes of each other.

the area of a small square is 25 square units what is the exact length in units of a single of a large square
Answer:
5
Step-by-step explanation:
The area of any quadrilateral can be determined by multiplying the length of its base by its height. Since we know the shape here is square, we know that all sides are of equal length. From this we can work backwards by taking the square root of the area to find the length of one side.

What is the midpoint of the segment shown below ? A. (1,5) B. (2,5), C ( 1 1/2,5), D. (2 1/2, 5)
The midpoint of the line segment is (2,5) (option B)
How do you find the midpoint of a line segment in a coordinate?When given the end points of a line segment, you can find out its midpoint by using the midpoint formula. As the name might have already suggested, midpoint is basically the halfway between two end points. All you need to do is dividing the sum of x-values and the sum of y-values by 2.
The sum of x coordinate is -1+5 = 4
half of sum of x coordinate = 4/2 = 2
The sum of y coordinate = 5+5= 10
half of sum of y coordinate = 10/2 = 5
therefore the midpoint of the line is ( 2,5)

At every company meeting, the president speaks for 28 minutes and then takes questions from her employees. Let q represent the number of minutes she spends answering questions and t represent the total number of minutes the meeting lasts.
Answer:
t = 20 + q in minutes
Step-by-step explanation:
Company meeting = president speech + questions + answers
President speech = 20 minutes
Questions and answers = q minutes
Total time spent = t minutes
Total time spent = President speech + Total time spent
t = 20 + q
The equation that represents the relationship between q and t is
t = 20 + q in minutes
Which equation is true of x is 3.5
Answer:
B
Step-by-step explanation:
Because 4 times 3.5 equals 14 and minus 3 equals -11 so its B.
Answer:
Your answer is B.
Step-by-step explanation:
The reason is because:
3-4x=-11
turns to
-4x=-14
when you subtract 3 from both sides then divide both sides by negative 4
and you get:
x=-14/-4
if you simplify -14/-4 your final answer will be
7/2 which equals 3.5: x=3.5
