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:

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 speed of a space station in orbit is about 1300 meters per second.How many kilometers per hour does the space station travel?

Answers

Answer:

4680 km / hour

Step-by-step explanation:

You can do this with a method called dimensional analysis. (I think you should check the speed. Are you sure it is that fast?)

[tex]\frac{1300 m}{sec}*\frac{1 km}{1000 m} * \frac{3600 sec}{1 hr}\\[/tex]

1.3 * 3600 = 4680 km/hour

Which expression represents the area in square feet that the homeowner will cover with fertilizer?

Answers

Question:

A homeowner is building a flower bed in the backyard. He plans to put a layer of fertilizer over the entire flower bed.

[tex]Length = 4w^2 + 3w - 1[/tex]

[tex]Width = 5w - 2.[/tex]

Which expression represents the area in square feet that the homeowner will cover with fertilizer?

Answer:

[tex]Area = 20w^3 + 7w^2 - 11w + 2[/tex]

Step-by-step explanation:

Given

[tex]Length = 4w^2 + 3w - 1[/tex]

[tex]Width = 5w - 2.[/tex]

Required

Determine an expression for the area

Area is calculated as:

[tex]Area = Length *Width[/tex]

[tex]Area = (4w^2 + 3w - 1) * (5w - 2)[/tex]

Expand

[tex]Area = 20w^3 + 15w^2- 5w - 8w^2 - 6w + 2[/tex]

Collect like terms

[tex]Area = 20w^3 + 15w^2- 8w^2 - 5w - 6w + 2[/tex]

[tex]Area = 20w^3 + 7w^2 - 11w + 2[/tex]

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

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

- 2x + 5 = 4
Need help solving

Answers

Answer:

x = 1/2 or 0.5

Step-by-step explanation:

-2x + 5 = 4

-2x = 4 -5

-2x = -1

-1(-2x = -1)

2x = 1

x = 1/2 or 0.5

-2x + 5 = 4 | minus 5 from both sides
-2x =4 -5
-2x = -1 | divide both sides by -2
x= 1/2
