Answer:
84miles
Step-by-step explanation:
Step one:
given data
we are told that the equation that describes the car's speed is
d = 70t-----------1
From the equation, we can see that the speed with which the car is traveling is 70miles per hour, while we are expected to find the distance d when the time is 1.2 hours.
Required
The distance d at 1.2 hours
Step two:
substituting in the expression we have
d= 70*1.2
d=84miles

Kareem cannot decide which of two washing machines to buy. The selling price of each is $480. The first is marked down by 30%. The second is marked down by 20% with an additional 10% off. Find the sale price of each washing machine. Use pencil and paper. Explain why Kareem should buy the first washing machine rather than the second if the machines are the same except for the selling price.
Answer:
1. $336
2.$345.6
Step-by-step explanation:
First off the first machine is cheaper because of the 30% off of the total price rather than 20 off the price then another 10 percent off that price.
mine says marked down by 30. then 10. then 20

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.

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)

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

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

A free cable sparkling juice calls for 1 1/2 quarters of sparkling water and 3/4 course with grape juice how many sparkling how much sparkling water would you need to mix with 9 quarts of grape juice
Answer: 18 quarts
Step-by-step explanation:
As per given,
Quantity of sparkling juice is proportional to quantity of course with grape juice.
Given: A free cable sparkling juice calls for [tex]1\dfrac12[/tex] quarters of sparkling water and [tex]\dfrac34[/tex] course with grape juice .
Let x be the quantity of sparkling water need to mix with 9 quarts of grape juice.
then, by equation of direct proportion , we have
[tex]\dfrac{1\dfrac12}{\dfrac34}=\dfrac{x}{9}\\\\\Rightarrow\dfrac{\dfrac{3}{2}}{\dfrac{3}{4}}=\dfrac{x}{9}\\\\\Rightarrow\ \dfrac21=\dfrac{x}{9}\\\\\Rightarrow\ x=9\times2\\\\\Rightarrow\ x=18[/tex]
Hence, the quantity of sparkling water need to mix with 9 quarts of grape juice = 18 quarts
