Shen drove 780 miles in 12 hours. At the same rate, how many miles would he drive in 5 hours?
Identify the angles that each have a measure of 124º.
Answer:
Angle 1, angle 3 and angle 7 will be the equal angles.
Step-by-step explanation:
In the figure attached,
Two lines are parallel and a transversal line is intersecting these parallel lines.
Congruent angles to the angle measuring 124° will be,
m(∠7) = 124° [Vertical angles]
m(∠1) = 124° [Corresponding angles]
m(∠3) = 124° [Alternate interior angles]
Therefore, ∠1, ∠7 and ∠3 will measure the same as 124°.

A camera is marked down from $36 to $27. What is the percent of the markdown
Answer:
75%
Step-by-step explanation:
You have to put 27/36 and multiply 27/36 by 100/1 and then you get 2700/36 and divide it and you get 75 so that is how you get 75%

3. Diego made the shape on the left, and Elena made the shape on the right. Each shape
uses 5 circles
Select all the true statements.
A. The smallest circle in Diego's design is congruent to the smallest circle in Elena's
design.
B. Diego's design is congruent to Elena's design
C. Elena's design is a translation of Diego's design
The two circle designs are missing, so i have attached it.
Answer:
Options A & B are true.
Step-by-step explanation:
Congruent circles are basically identical. This means that they have the same radius and diameter but different centres.
Now, from the attached image, we see that the smallest circle in diogo's design has diameter of 2 units & radius of 1 unit while the one in Elena's design also has exactly the same measurement. Thus, we can conclude the smallest circle in diogo's design which is the first one is congruent to the smallest circle in the second design for Elena.
So option A is correct.
Looking carefully at both designs, we can observe that one is concentric while the other is eccentric. However, all the similar sized circles have the same radius & diameter. Thus, we can still say that both designs are congruent. So option B is correct.
In transformations, a translation is when all the points in a an object are made to move up or down in a state straight line in that same direction. However, the objects shape and size remains the exactly the same.
In this case, it's not so because the circle changed from concentric circles to eccentric circles. So this option C is not correct.

Which of the following is the best example of a system of equations that should be solved by the elimination method?
Question 2 options:
8x + 3y = 2
5x + 8y = -11
2x - 4y = -16
y = 5x + 13
-8x - 9y = -17
16x - 4y = 12
12x + 7y = -17
9x + 11y = -7
Answer:the answer -8x-9y=-17
16x-4y=12
Step-by-step explanation:
divide 16x-4y=12 with 2
8x-2y=12
Then add the equations
-8x-9y=-17
8x-2y=12
0-11y=-23
You can’t do this with the other equations provided.

I earn 770.98(R) every week. I have 385.49(R) since I spent the other half on toys. I want extra items on a game, but it's 1,541.72(R). How long will I have to wait until I save enough money for it? 385.49 + 770.98 < 1,541.72. (It's in Russian dollar so lemme translate) 385.49 = 5 US dollar) 770.98 = 10 US dollar) 1,541.72 = 20 US dollar)
Answer:
1.5 weeks
Step-by-step explanation:
Given
[tex]Earnings = 770.98[/tex] weekly
[tex]Amount\ Left = 385.49[/tex]
[tex]Game\ Cost = 1541.72[/tex]
Required
Determine the time taken to save up
Represent the time with t
The relationship between the given parameters can be expressed as:
Amount + Earnings in t weeks = Game Cost
This gives:
[tex]385.49 + 770.98t = 1541.72[/tex]
Collect Like Terms
[tex]770.98t = 1541.72 - 385.49[/tex]
[tex]770.98t = 1156.23[/tex]
Solve for t
[tex]t = 1156.23/770.98[/tex]

24. Janet and Jack are walking in a two-day event to raise money for charity.
Janet asks a friend for a $7.50 donation, plus $0.10 for each mile she
walks. Jack asks a friend for a $5.50 donation, plus $0.15 for each mile
he walks. At how many miles of walking would Janet and Jack collect the
same amount of money?
Answer:
40 miles walk
Step-by-step explanation:
Let the miles walked by both of them be x at which money collected by same
for Janet
Fixed donation asked = $7.50
money asked for walking 1 mile = $0.10
money made by Janet if he walks x miles = x*$0.10 = $0.10x
Total money collected by Janet = Fixed donation asked + money made by Janet if he walks x miles
Total money collected by Janet =7.50 + 0.10x
For Jack
Fixed donation asked = $5.50
money asked for walking 1 mile = $0.15
money made by Janet if he walks x miles = x*$0.15 = $0.15x
Total money collected by Jack = Fixed donation asked + money made by Jack if he walks x miles
Total money collected by Jack =5.50 + 0.15x
we have to find miles at which money collected by both of them be same
and we have decided that it it as x mile walk then
Total money collected by Janet = Total money collected by Jack
7.50 + 0.10x = 5.50 + 0.15x
=> 7.50 - 5.50 = 0.15x - 0.10x
=> 2 = 0.05x
=> x = 2/0.05 = 40
Thus, at 40 miles walk money collected by both of them will be same

The circumference of a circle is 10 inches. What is its area in square inches?
Answer:
7.96 square inches.
Step-by-step explanation:
Area of a circle given a circumference is given by formula:
[tex]A = \frac{C^{2}}{4\pi}[/tex]
So substituting into equation we have: [tex]C= 10[/tex].
Therefore [tex]A = 10^{2}/4\pi = 100/4\pi=25/\pi =7.96[/tex] square inches.
The area of the circle is 7.96 square inches if the circumference of a circle is 10 inches.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
It is given that:
The circumference of a circle is 10 inches.
As we know the circumference of a circle is given by:
C = 2πr
C is the circumference of the circle.
r is the radius of the circle.
10 = 2πr
r = 5/π inches
As we know,
The area of the circle is given by:
A = πr²
Here, A represents the area of the circle.
Plug the value of the radius r in the above formula:
A = π(5/π)²
A = 25/π square inches
Take π = 3.14
A = 25/3.14
A = 7.96 sqaure inches
Thus, the area of the circle is 7.96 square inches if the circumference of a circle is 10 inches.
