CF = FG = GC because it is equilateral triangle

So
3x + 0.8 = 2x + 3

3x–2x = 3 – 0.8

X = 2.2

Putting this value to DE

IT IS ALSO A EQUILATERAL TRIANGLE

SO
5x + 4 = 5× 2.2 +4 =

11+4 = 15

All side will be 15 of triangle CD = DC = CE = 15

Answer:

$CD=13.6$

Step-by-step explanation:

We have been given a triangle CDE in which GF is mid-segment. we are asked to find the value of CD.

We know that the length of mid-segment of a triangle is half the measure of third side.

Using triangle mid-segment theorem, we can set an equation as:

$2(2x+3)=5x+4$

$4x+6=5x+4$

Switch sides:

$5x+4=4x+6$

$5x-4x+4=4x-4x+6$

$x+4=6$

$x+4-4=6-4$

$x=2$

Since F is midpoint of CD, so we can set an equation as:

$CD=2(3x+0.8)$

$CD=2(3(2)+0.8)$

$CD=2(6+0.8)$

$CD=2(6.8)$

$CD=13.6$

Therefore, the length of CD is 13.6 units.

What is 49.6 divided by 7.8?

fomenos

Answer: 6.4

Step-by-step explanation: If rounding to one decimal place, your answer would be 6.4.

49.6 divided by 7.8 = 6.35897435...

Now, we see that after the 3 (The first decimal place) there is a five. Because we are rounding to the first decimal place the second decimal place will tell us to round up or down. In this case because it's a five, we would round up.

Find the difference between (-11,-11) and (-12,-8) round answer to the nearest hundredth

lisov135 [29]

Answer:

Step-by-step explanation:

The two points can be made into a right triangle with the two sides defined by two lines drawn from the two given points. Use the Pythagorean Theorem to solve for the hypotenuse, the distance between the two points. See attached graph.

6^2 + 2^2 = x^2

36 + 4 = x^2

x^2 = 40

x = 6.32

Find the perimeter and the area of the polygon with the given vertices.

7nadin3 [17]

Answer:
Area : 45 Perimeter : 2,025

Explanation:
Area: 5 times 9 equals 45. The 5 is the polygon’s base, the 9 is the polygon’s height.
Perimeter: 5 times 5 times 9 times 9 equals 2,025. Perimeter is base times base times height times height.

Glad I could help! :)

Venn diagram ( attached image )

alexandr402 [8]

Assessing the given Venn diagram and the data related to it, we can answer the required question:

Q1. How many people were surveyed = 86.

Q2. What is the probability that a customer chosen at random:

a) takes salt P(S) = 46/85.

b) takes both salt and vinegar P(S ∩ V) = 13/85.

c) takes salt or vinegar or both P(S ∪ V) = 66/85.

The number of people who take salt chips n(S) = 46.

The number of people who take vinegar chips n(V) = 33.

The number of people who takes both n(S ∩ V) = 13.

The number of people who take neither n((S ∪ V)') = 19.

Therefore, the total number of people surveyed n(U) = n(S) + n(V) - n(S ∩ V) + n((S ∪ V)') = 46 + 33 - 13 + 19 = 85.

The number of people who takes salt or vinegar or both n(S ∪ V) = n(U) - n((S ∪ V)') = 85 - 19 = 66.

The probability that a customer chosen at random takes salt P(S) = n(S)/n(U) = 46/85.

The probability that a customer chosen at random takes both salt and vinegar P(S ∩ V) = n(S ∩ V)/n(U) = 13/85.

The probability that a customer chosen at random takes salt or vinegar or both P(S ∪ V) = n(S ∪ V)/n(U) = 66/85.
