Answer:
Basic Concept used:
Since D is the mid-point of EF,
ED will be equal to DF since D is in the middle of the line segment
We are given the following values for ED and DF
ED = 4x + 6 and DF = 7x - 9
Solving for x:
Since ED = DF (D is the mid point)
4x + 6 = 7x - 9
9 + 6 = 7x - 4x
15 = 3x
x = 5
Finding the values of ED , DF and EF:
we know that x = 5 (from the last section)
we are given the following values of the line segments:
ED = 4x + 6
DF = 7x - 9
EF (ED + DF) = (4x + 6) + (7x - 9)
Replacing x with 5 in each of these equations:
ED = 4(5) + 5 = 26
DF = 7(5) - 9 = 26
EF = (4(5) + 6) + (7(5)-9) = 26 + 26 = 52

Because a trangle have 180 degree inside
Answer:
Step-by-step explanation:
second one - for this one you would do 90 +30 = 120
then take this from 180 to get 60 . so if you can see that the shape is an f but that's if you take away the sides with the right angles . the corresponding angle rule (you can see an F shape) means that the angle that i just worked out is the same as angle c so angle c=60
third one - for this one do 70+30 then take this answer away from 180
that angle x
the rule for angle y is the vertically opposite angle rule - angle s that are vertically opposite are the same angle y= angle x - same angle

Can someone help me figure out what are the two checkpoints?
Answers
Answer:
13,000 ft.
Step-by-step explanation:
X -------10960----------C---------------D---------------Y
The entire race (from X to Y) is 7 miles. There are 5,280 ft. in one mile, so 7 miles is 36960 ft.
If we subtract 10,960 from 36,960, then we get the distance from C to Y.
36960-10960 = 26000
They tell you D is at the midpoint between C and Y
So if we divide 26,000 by 2, then we know the distance from C to D and from D to Y.
26000/2 = 13000
The checkpoints are C and D, so the distance between them is 13,000 ft.

Step-by-step explanation:
We need to isolate the variable.
1. Subtract 4.5s from both sides
2. We now have the equation -4s+1=7

The measure of an angle is 53.8°. What is the measure of its complementary angle?
Answers
Step-by-step explanation:
Complementary angles means that the angles should add up to 90°.
let the complementary angle of 53.8° is x°.
So,
53.8° + x° = 90°.
x° = 90°-53.8°
x = 36.2°

area and percent .
Answers
Answer:
a. 61.92 in²
b. 21.396 ≈ 21.4%
c. $4.71
Step-by-step explanation:
a. Amount of waste = area of rectangular piece of stock - area of two identical circles cut out
Area of rectangular piece of stock = 24 in × 12 in = 288 in²
Area of the two circles = 2(πr²)
Use 3.14 as π
radius = ½*12 = 6
Area of two circles = 2(3.14*6²) = 226.08 in²
Amount of waste = 288 - 226.08 = 61.92 in²
b. % of the original stock wasted = amount of waste ÷ original stock × 100
= 61.92/288 × 100 = 6,162/288 = 21.396 ≈ 21.4%
c. 288 in² of the piece of stock costs $12.00,
Each cut-out circle of 113.04 in² (226.08/2) will cost = (12*113.04)/288
= 1,356.48/288 = $4.71.

Simplify square root -200
Answers
Answer:
10 i sqrt 2
Step-by-step explanation:
i indicates that it is an imaginary number. this is because 200 is negative.
The simplified form of the given square root number is 10i√2. Therefore, the correct answer is option D.
The given square root number is √-200.
The square root of a number is the inverse operation of squaring a number. The square of a number is the value that is obtained when we multiply the number by itself, while the square root of a number is obtained by finding a number that when squared gives the original number.
Here, 200 = 2×2×2×5×5
Thus, √-200=√-2×2×2×5×5
=2×5×i√2
= 10i√2
Therefore, the correct answer is option D.

I would say that shape E and A has symmetry.
Step-by-step explanation:
The line of symmetry means that on both sides of the shape from the middle part, it is equal. For example, a square has symmetry because it is equal when you split in in half.
If you were to rotate E and A a little, the slice it in half, it is equal on both sides, thus having symmetry.
