if we take 4c to be the 100%, what is 0.2c off of it in percentage?
[tex]\begin{array}{ccll} a&b\\ \cline{1-2} 4c & 100\\ 0.2c& x \end{array} \implies \cfrac{4c}{0.2c}~~=~~\cfrac{100}{x}\implies \cfrac{4}{0.2}~~ = ~~\cfrac{100}{x} \\\\\\ 4x=20\implies x=\cfrac{20}{4}\implies x=5[/tex]
PLSS HELPPP!!!!!! HURRYYY!!! THXXX!!!Kylie compared the price per pound of two types of apples at her grocery store. She used the equation y=0.85x to represent y, the total cost in dollars of x pounds of apple A. She entered into the table below the cost of some weights of apple B.
What is the difference in the price per pound between apple A and apple B?
A
$0.40
B
$0.85
C
$1.25
D
$2.10
Answer:
Choice A is the correct answer.
Step-by-step explanation:
We can compare the prices by taking one of the weight values from the table for apple B and plug it into the equation for apple A.
For example, let's take 4 from the table. The equation would look like this:
y = 0.85(4) = $3.40.
This is the price of 4 pounds of apple A. However, the price for 4 pounds of apple B is $5.00.
5.00 - 3.40 = $1.60. This is the difference in price between 4 pounds of apple A and 4 pounds of apple B. If we want to find the difference per 1 pound, just divide 1.60 by 4.
1.60 / 4 = $0.40.
Therefore, the answer is Choice A.

The populations of two cities after t years can be modeled by -150t+50,000 and 50t+70,0000 . What is the difference in the populations of the cities when t=4
Answer:
25,800
Step-by-step explanation:
Plug in 4 everytime you see T.
multiple-150 times 4 plus 50000 which gives you 49,400.
then multiple 50 times 4 and add 75000, giving you 75,200 then subtract 75,200 - 49,400 which you end up with 25,800.
hope this helped
HELP PLEASEE and thank youuu Find and interpret the mean absolute deviation of the data. 94,86,95,99,88,90 The mean absolute deviation is____. The values differ from the mean by an average of_____.
Step-by-step explanation: First of all the first step to find the mean absolute deviation you need to add 94, 86, 95, 99, 88 and 90 and then divide 552 which is the result that you get when you add by 6 getting an answer of 92. Second you need to find the distance or deviation but remember put those signs of absolute value when you find the answer.
remember the rule of absolute value which is that all numbers are always positive.
94-92= |2|
86 - 92= |6|
95-92=|3|
99-92=|7|
88-92=|4|
90-92=|2|
The final steps are to find the mean of the results you get when you subtract the deviation.
2+6+3+7+4+2= 24/6=4 is the absolute deviation
The mean absolute deviation is 4. The values differ from the mean by an average of 4.
Sorry if i got it wrong the last one and hopefully those are the correct answers.
1/10x+9/10=1/10(BLANK)
Answer:
x=-8
Step-by-step explanation:
1 Simplify 1/10x to x/10.
x/10 + 9/10 = 1/10
2 Join the denominators.
x+9/10 = 1/10
3 Multiply both sides by 10.
x+9 = 1/10×10
4 Cancel 10.
x+9=1
5 Subtract 9 from both sides.
x=1-9
6 Simplify 1-9 to -8.
x=-8

Answer:
D. $67.50
Step-by-step explanation:
A ticket costs $5.25, a drink costs $2.00, and a popcorn costs 4.00. Each person in the group buys all of these. So we know that each person is paying:
4.00 + 2.00 + 5.25 = 11.25
Since there are 6 people in the group we can multiply that by 6:
11.25 * 6 = 67.50

Find the area of the composite figure to the nearest half unit. Use 3.14 for π
Answer:
23.5 cm^2
Step-by-step explanation:
First calculate the "rectangle" with the half-circle filled in
9*3 = 27
Then calculate the half-circle using the formula for the area of a circle [tex]\pi r^{2}[/tex], then dividing it by half
3.14 * 1.5 * 1.5 / 2 = 3.5325
Subtract the area of the half-circle from the area of the rectangle
27-3.5325
= 23.4675
= 23.5 (cor. to the nearest half unit)

How would you use the coordinate plane to determine the area of Figure 3 on the graph below?
To identify the area of the figure, the amount it occupies on the x-axis and on the y-axis must be identified, and finally it must be multiplied.
How to identify an Area with the Coordinate Plane?To identify the area of figure 3, its extension must first be identified on one of the axes, for example, the x-axis, where its extension is:
Extension of the figure on the x axis = 2 (since it goes from 7 to 9).Then its extension on the y-axis must be identified, which is:
Extension of the figure on the axis y = 5 (since it goes from 5 to 10)Finally, the two visualized extensions must be multiplied to obtain the area of the figure:
Figure area = Extension x * Extension yArea of the figure = 2 * 5Figure area = 10Units are not used as they are not specified in the drawing or information, but could be square inches or square feet.
