![In This Picture B,D, And Faremidpoints. AC=50, CE=60, AndBD=35DF=[?]](https://brainimage.s3.us-east-005.backblazeb2.com/contents/attachments/e2e2vi2sNcJ9c9aZwXglapQ3SUcg8JJg.png)
Answers
Answer:
25
Step-by-step explanation:
The smaller triangle is constructed by joining the 3 midpoints. Every line in that smaller triangle is parallel and 1/2 the size of the line not joined by the 2 given midpoints.
In this case 1/2 AC = 1/2 * 50 = 25
The length of DF = 25

170=c^2
then square it
c=13
7,11,13 is a pythagorean triple
Answer:
both answers you have put in are correct
Step-by-step explanation:
7^2=49
11^2=121
121+49=170
square root of 170 is the long side
not a pythagorean triple because square root of 170 does not come out as a whole number (no decimal/fraction)

Answer:
10.5
Step-by-step explanation:
Both widths are the same in a rectangle. So both are 6.5. Then you subtract 13 from 34. Now you are left with 21. No divide that by two to get your two lengths. That is l. L=10.5
Answer:
Step-by-step explanation:
P=2L+2W
P=34 W= 6.5
34=2L+2*6.5
34=2L+13
2L=21
L=10.5
or
Given:
P = 34 [Perimeter]
W = 6.5 {let's use W and L to make it easy to read]
Also known:
P = W + L + W + L = 2(W+L)
Fill in values:
34 = 2(6.5+L) [NOTE: This is an equation to determine the length (L) of the rectangle."]
. . .
17 = 6.5 + L [NOTE: This is a simplified form of the above equation.]
. . .
10.5 = L [NOTE: This is the solution (the value of L)]

Step-by-step explanation:
We have |E - G| = 12.
=> E - G = 12 or E - G = -12
=> (-1) - G = 12 or (-1) - G = -12
=> G = -13 or G = 11.
Coordonates of G could be -13 or 11.

Answers
Given :
A salesperson at a jewelry store that earns 7% commission each week last week Jared sold $680 worth of jewelry.
To Find :
How much did he make in commission.
Solution :
Let, commission he make is C.
So, C is 7% of $680 .
[tex]C = \dfrac{680\times 7}{100}\\\\C = \$ 47.6[/tex]
Therefore, salesperson will make $47.6 commission.
A rock climber begins climbing at an altitude of 120 meters. She climbs at a rate of 50 meters per hour. Which equation can be used to find the altitude of the rock climber, y, after x hours?
Answers
Answer:
y=50x+120
Step-by-step explanation:
y is the ending altitude
x is the number of hours the climber has climbed
put 50 before x because that how fast the climber is climbing
then 120 is your y intercept
y = 2x - 1
y=-3x + 4

The total distance in centimeters a toy robot moves varies directly with the time in seconds. The toy robot moves a total distance of 264 centimeters in 11 seconds.
Answers
Answer: 17 seconds
Step-by-step explanation:
Here's the complete question:
The total distance in centimeters a toy robot moves varies directly with the time in seconds. The toy robot moves a total distance of 264 centimeters in 11 seconds. What is the time in seconds the toy robot moves when the total distance is 408 centimeters?
First, we find the constant of proportionality which will be:
y = kx
where y = Distance; x = time
264 = 11k
k = 264/11
k = 24
The time in seconds the toy robot moves when the total distance is 408 centimeters will be:
y = kx
408 = 24x
x = 408/24
x = 17
Answer:
17 secs

Step-by-step explanation:
The formula for this kind of question is
Area of sector = x / 360 * pi * r^2 = 24*pi
x/360 * pi * 12^2 = 24 pi
x/360 * pi * 144 = 24 pi the pi s cancel out
x / 360 = 24/144 Multiply both sides by 360
x = 24 * 360/144
x = 60
