Answers

Answer:

x = 4

Step-by-step explanation:

In similar triangles, the ratios of the length of the corresponding sides are equal.

[tex]\frac{CD}{ED}=\frac{GD}{FD}\\\\[/tex]

[tex]\frac{48}{5x-2}=\frac{40}{2x+7}\\[/tex]

Cross multiply,

48*(2x + 7) = 40*(5x - 2) {use distributive property: a*(b+c)=(a*b)+ (a*c)}

48*2x  + 48*7 = 40*5x - 40*2

  96x  + 336   = 200x - 80       {Subtract 96x from both sides}

             336   = 200x - 96x - 80

               336 =  104x - 80 {Add 80 to both sides}

      336 + 80 = 104x

               416 = 104x      {divide both sides by 104}

        416/104 = x

x = 4

Find the value of x. Write your answer in simplest form.

Ellie works at a camp . Her age is a multiple of 6 and a multiple of 8 . What is the youngest age Ellie could be ?

Answers

Answer:

24

Step-by-step explanation:

Write down 6 and 8 on a piece of paper. Write down all the multiples of 6 (6, 12, 18...) and do the same for 8 (8, 16, 24). Stop at the 12th multiple. (For six it's 72, and for 8 it's 96. ) Go over all the multiples and see if there are any answers that are alike. (Sometimes there isn't any so keep the pattern going.) For this example, some multiples that they share are 24, 58, and 72. The one that is the lowest is 24. Ellie is 24.

The height of an overhand volleyball serve can be modeled as h=-16t^2+20t+6. After how many seconds is the ball 11 feet.

Answers

Answer:

0.9043secs and 0.3456secs

Step-by-step explanation:

Given the height of an overhand volleyball modeled as h=-16t^2+20t+6.

If the height is 11feet, then;

11 = -16t^2+20t+6.

-16t^2+20t+6 - 11 = 0

-16t^2+20t-5 = 0

Multiply thriugh by -1

16t^2-20t+5 = 0

Factorize

t = 20±√20²-4(16)(5)/2(16)

t = 20 ±√400-320/32

t = 20 ±√80/32

t = 20 ±4√5/32

t = 20±8.94/32

t = 28.94/32 and 11.06/32

t = 0.9043 and 0.3456

Hence the required time are 0.9043secs and 0.3456secs
