Answer:
The original cost is $130
Step-by-step explanation:
Step one:
given data
We are told that Rey paid $91 for a watch that was on sale for 30%
let the original cost be x
so that 30% off x= $91 --------not the word OFF not OF
Required
the original cost x
Step two
hence
x- 30/100*x= 91
x-0.3x=91
0.7x= 91
divide both sides by 0.7
x= 91/0.7
x=$130

7. Triangles CDE and RST are similar triangles. What is
the length of side CD in triangle CDE?
R
40 ft.
32 ft.
20 ft.
T
S
Answer:
CD = 25 ft
Step-by-step explanation:
[tex] \triangle CDE \sim \triangle RST[/tex]
[tex]\therefore \frac{CD}{20}=\frac{40}{32}[/tex]
(Corresponding sides of similar triangles are in proportion)
[tex]\therefore \frac{CD}{20}=\frac{5}{4}[/tex]
[tex]\therefore CD = \frac{5}{\cancel 4}\times \cancel {20} \:\:\blue{\bold{5}} [/tex]
[tex]\therefore CD = 5\times 5[/tex]
[tex]\therefore CD = 25\: ft[/tex]
Answer:
CD = 25 ft
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{CD}{RS}[/tex] = [tex]\frac{CE}{RT}[/tex] , substitute values
[tex]\frac{CD}{20}[/tex] = [tex]\frac{40}{32}[/tex] ( cross- multiply )
32CD = 800 ( divide both sides by 32 )
CD = 25

What is the measure of angle F in degrees?
6x + 10 = - 2y
y=mx+b
Answer:
y = -3x - 5
Step-by-step explanation:
-2y = 6x + 10
divide both sides by -2
y = -3x - 5

A. $5
B. $12
C. $6
D. $1
The graph isn't included in this answer,but if he downloads 12 songs,his total will be 12 dollars spend, Assuming that Lanise's plan is cheaper than Connor's it would have to be between A,B with a possibility of D.

Step-by-step explanation:
A density graph for all the possible speeds between 0 mph and 320 mph is in the shape of a triangle. What is the height of the triangle?
A. 0.025
B. 0.0125
C. 0.003125
D. 0.00625
The height of the triangle is 0.00625.The correct option is D
To solve this problem
A density graph must have an area under it equal to 1. The range of speeds in this problem, 320-0 = 320, is the base of the density graph, which is shaped like a triangle. By multiplying the base by half of the triangle's height, we can determine the density graph's area.
Let h represent the triangle's height. The triangle's area is then:
1 = (1/2)320h
calculating h:
h = 1 / (320/2) = 0.00625
Therefore, option D is appropriate because the triangle's height is 0.00625.

A summer camp cookout is planned for the campers and their families. There is room for 200 people. Each adult costs 4, and each camper costs4,and each camper costs3. There is a maximum budget of $750. Write the system of inequalities to represent this real-world scenario, where x is the number of adults and y is the number of campers.
A. \begin{gathered}x + y \leqslant 200 \\ 4x + 3y \leqslant 750\end{gathered}x+y⩽2004x+3y⩽750
B. \begin{gathered}x + y \leqslant 750 \\ 4x + 3y \leqslant 200\end{gathered}x+y⩽7504x+3y⩽200
C. \begin{gathered}x + y \leqslant 200 \\ 3x + 4y \leqslant 750\end{gathered}x+y⩽2003x+4y⩽750
D. \begin{gathered} x + y \leqslant 750 \\ 3x + 4y \leqslant 200\end{gathered}x+y⩽7503x+4y⩽200
Answer:
Option A
The system of inequalities
x + y ≤ 200
4x + 3y ≤ 750
Step-by-step explanation:
Let the
Number of Adults = x
Number of campers = y
A summer camp cookout is planned for the campers and their families.
There is room for 200 people.
x + y ≤ 200
Each adult costs $4, and and each camper costs $3. There is a maximum budget of $750.
Maximum means the total cost is equal to or less than $750
$4 × x + $3 × y ≤ $750
4x + 3y ≤ 750
The system of inequalities
x + y ≤ 200
4x + 3y ≤ 750
Option A is correct

y = 10 + x
O one solution
O no solution
O many solutions
Answer:
0ne solution; x = 5
Step-by-step explanation:
if y equals both 5x - 10 and 10 + x then you can do the following:
5x - 10 = 10 + x
4x = 20
x = 5
Jane paid $40 for an item after she received a 20% discount. Jane's friend says this means that the original price of the item was $48. a. How do you think Jane's friend arrived at this amount?
Answer:
The discount is $8
Step-by-step explanation:
Step one
Given data
Jane paid $40 for an item after she received a 20% discount.
Required
The initial cost of the item
Now in other to check whether Jane's friend is correct, let us solve for the initiai cost as follows
Let the initial cost be x
so
20% of 40
20/100*40
=0.2*40= $8
Therefore the discount is $8
hence the original price is
discount+ discounted sale(amount paid)
=8+40
=$48

Step-by-step explanation:
what is the slope of the line
2x+12y-192
Answer:
-1/6
Step-by-step explanation:
To get the slope we need the equation in the form y=mx+c, and m is the slope.
2x+12y=192
12y = -2x + 192
y = -2/12 x + 16
-2/12 is the slope but this can be simplified to -1/6
