how

21/9 = 2.3333333333

Step-by-step explanation:

Given:

Point F,G,H are midpoints of the sides of the triangle CDE.

[tex]FG=9,GH=7,CD=24[/tex]

To find:

The perimeter of the triangle CDE.

Solution:

According to the triangle mid-segment theorem, the length of the mid-segment of a triangle is always half of the base of the triangle.

FG is mid-segment and DE is base. So, by using triangle mid-segment theorem, we get

[tex]\dfrac{1}{2}DE=FG[/tex]

[tex]DE=2(FG)[/tex]

[tex]DE=2(9)[/tex]

[tex]DE=18[/tex]

GH is mid-segment and CE is base. So, by using triangle mid-segment theorem, we get

[tex]\dfrac{1}{2}CE=GH[/tex]

[tex]CE=2(GH)[/tex]

[tex]CE=2(7)[/tex]

[tex]CE=14[/tex]

Now, the perimeter of the triangle CDE is:

[tex]Perimeter=CD+DE+CE[/tex]

[tex]Perimeter=24+18+14[/tex]

[tex]Perimeter=56[/tex]

Therefore, the perimeter of the triangle CDE is 56 units.

Answer:

C is correct

Step-by-step explanation:

Answer:

area = 779.4 cm²

Step-by-step explanation:

divide it into 6 equal equilateral triangles. Each corner of a triangle will be 60°.

tan 60° = 15/x

1.7321 = 15/x

x = 8.66 (this is one-half of the base of the triangle)

base = 17.32 cm

area of one triangle = 1/2(17.32)(15) = 129.9 cm²

129.9(6) = 779.4 cm²   (because 6 triangles make up the hexagon)

Answer:

4(x + 1)^2 - 12.

Step-by-step explanation:

f(x) = 4x^2 + 8x - 8

f(x) = 4(x^2 + 2x) - 8

f(x) = 4[(x + 1)^2 - 1) - 8

f(x) = 4(x + 1)^2 - 4 - 8

f(x) = 4(x + 1)^2 - 12.

Answer:

x=30

Step-by-step explanation:

The figure on the right has 12 in. on one side and 10 on the other and the figure on the left is 3 times the number that the figure on the left has. When you multiply 3 and 12 you get 36. From there on you can infer that you multiply 10 by 3. Your solution to x is 30.

Answer: 30

Step-by-step explanation:

36/3=12, 30/3=10

Answer:

63 in³

Step-by-step explanation:

Volume = l×w×h

2¼ = 9/4

8 = 8/1

3½ = 7/2

V = 9/4 × 8/1 × 7/2

= 504/8

= 63

So, the answer is 63 in³.

Answer:

24 beach toys

Step-by-step explanation:

We don't know how many beach toys Theo has, but we know that 6 of his friends each got 4 toys. The equation could be set up as x/6 = y, where x is equal to the total amount of toys Theo had, and y is equal to the amount of toys each friend received. We know that y = 4, so now you could say x/6 = 4, and now using opposite operations, 6 × 4 = 24, hence Theo had 24 toys.

Answer:

No of hits = 26

Step-by-step explanation:

Given that,

Batting average = 0.4727272

His player has 55 at bats.

We need to find the number of hits. Let the number of hits be x. Using formula for average as :

[tex]\dfrac{x}{55}=0.4727272\\\\x=0.4727272\times 55\\\\x=25.99\\\\or\\\\x=26[/tex]

So, there are 26 number of hits.

Answer:

Loss= $175

Loss %= 7%

Step-by-step explanation:

First of all, you find the difference between 2500 and 2325 which is 175, as his has decreased, it is a loss of $175

To find the percentage you do the difference over the original amount

So 175/2500 which will give you 0.07

0.07 x 100 will give you 7%

Step-by-step explanation:

The graph of  y=-x^2-12x-35 is attached and it has x intercepts at x=-7 and x=-5 and vertex is at (6, -107).

A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .

To graph the equation y=-x^2-12x-35, we can start by finding the x-intercepts (or roots) and the vertex of the parabola.

To find the x-intercepts, we can set y=0 and solve for x:

0 = -x² - 12x - 35

Using the quadratic formula, we get:

x=-b±√b²-4ac/2a

x=12±√144-140/2(-1)

x=12±√144-140/(-2)

x=12±2/(-2)

The x-intercepts are approximately x=-7 and x=-5

To find the vertex, we can use the formula x=-b/2a to get the x-coordinate, and then substitute it into the equation to get the y-coordinate:

x = -b / 2a = -(-12) / 2(-1) = 6

y = -x² - 12x - 35 = -(6)^2 - 12(6) - 35 = -107

So the vertex is at (6, -107).

Hence, the graph of  y=-x^2-12x-35 is attached and it has x intercepts at x=-7 and x=-5 and vertex is at (6, -107).

Step-by-step explanation:

Since Tim's family toured the Astronaut Hall of Fame from 2:05P.M. To 2:45 P.M, the time taken during the tour will be:

= 2.45 pm - 2.05pm

= 40 minutes.

Since Tim's family toured the Astronaut Hall of Fame for 40 minutes, this shows that they spent more than 30 minutes during the tour.
