Answer:

D. y=70x

Step-by-step explanation:

The cheetah was clocked running 70 miles per hour.

i.e. in 1 hour cheetah covered 70 miles

in 2 hours cheetah covered 140 miles

in 3 hours cheetah covered 210 miles

in general, in n hour cheetah covered 70n miles

If y denote the distance covered

and x denotes the time cheetah runs

Then, y=70x

Hence, the equation which shows the relationship between the distance, y, and time, x, the cheetah runs is:

D  y=70x

Answer:  48 square units

=============================================================

Explanation:

Draw a vertical line to cut the triangle into two equal parts. You'll get two right triangles.

The horizontal leg of one of those smaller triangles is 12/2 = 6 units. The hypotenuse is 10 units. Through the pythagorean theorem, you should find the vertical leg is 8 units.

We have a 6-8-10 right triangle.

The area of this smaller triangle is base*height/2 = 6*8/2 = 48/2 = 24 square units.

So the area of the larger triangle is 2*24 = 48 square units.

==================================================

Explanation:

Let's say we had the slots A,B,C,D,E,F. Each slot represents where a flower would go.

For slot A, we have 15 different flowers to pick from.

Then slot B has 15-1 = 14 choices

C has 15-2 = 13 choices

and so on. We count our way down until we fill up slot F.

The count down looks like this: 15, 14, 13, 12, 11, 10

Multiply out those values: 15*14*13*12*11*10 = 3,603,600

If order mattered, then this represents the number of ways to select 6 flowers from a pool of 15 total.

However, order does not matter in this case. All that matters is the group overall.

For any group of 6 items, we have 6! = 6*5*4*3*2*1 = 720 different arrangements. That means the value 3,603,600 is too large exactly by a factor of 720.

We divide by 720 to get to (3,603,600)/720 = 5005 which is the final answer

It's the number of combinations where we select 6 from a pool of 15.

-------------------------------

As you can guess, you could use the nCr combination formula as an alternative route. Plug in n = 15 and r = 6 like so

[tex]_n C _r = \frac{n!}{r!*(n-r)!}\\\\_{15} C _{6} = \frac{15!}{6!*(15-6)!}\\\\_{15} C _{6} = \frac{15!}{6!*9!}\\\\_{15} C _{6} = \frac{15*14*13*12*11*10*9!}{6!*9!}\\\\_{15} C _{6} = \frac{15*14*13*12*11*10}{6!}\\\\_{15} C _{6} = \frac{15*14*13*12*11*10}{6*5*4*3*2*1}\\\\_{15} C _{6} = \frac{3,603,600}{720}\\\\_{15} C _{6} = 5005\\\\[/tex]

In the third to last step, notice how we have the 15*14*13*12*11*10 up top and 6*5*4*3*2*1 down below.

This value 5005 can be found in Pascal's Triangle. Look in the row that has 1, 15, ... and count out 7 spaces from the left. You should arrive at 5005. However, you'll need a fairly large Pascal's Triangle to use this method.

Given:

Total number of flower cuts = 15 different flowers

Number of flowers Jeanine Baker wants to use = 6 flowers

To find:

Total number of ways 6 flowers can be chosen

Steps:

In this question, we need to find the total number of outcomes of choosing 6 random flowers from a total of 15 flowers

Let's give each flowers a letter, so there will be A, B, C, D, E, F, G, H, I, J, K, L, M, N and O.

Now let's find all the outcomes

Outcomes= ABCDEF, ABCDEG, ABCDEH, ABCDEI, ABCDEJ, ABCDEK, ABCDEL, ABCDEM, ABCDEN, ABCDEO.....

This method will take a lot of time so, i am going to use the formula

[tex]No.outcomes = \frac{n!}{r!(n-r)!}[/tex]

Here n = total number of items, and r = number of items chosen

Also the '!' means factorial, or the product of all positive numbers less then or equal to the number, so n! = n * (n-1) * (n-2) ..... * 1

So, now substituting the formula

[tex]No.outcomes = \frac{15!}{6! * (n-r)!}[/tex]

[tex]No.outcomes=\frac{15!}{6! * 9!}[/tex]

[tex]No.outcomes = \frac{15*14*13*12*11*10*9*8*7*6*5*4*3*2*1}{6*5*4*3*2*1*9*8*7*6*5*4*3*2*1}[/tex]

[tex]No.outcomes=\frac{15*14*13*12*11*10}{6*5*4*3*2*1}[/tex]          (cutting same numbers)

[tex]No.outcomes = \frac{7*13*3*11*10}{6}[/tex]                 (simplifying)

[tex]No.outcomes = \frac{30030}{6}[/tex]

[tex]No.outcomes=5005[/tex]

Therefore, the total number of ways the 6 flowers can be chosen is 5005 ways

Answer:

21cm

Step-by-step explanation:

A scale drawing is a reduced form in terms of dimensions of an original image / building / object

the scale drawing is usually reduced at a constant dimension

scale of the drawing = original dimensions / dimensions of the scale drawing

Answer:

Can you please send the length of the height if possible.

Step-by-step explanation:

Also the the formula to solve this is the exact opposite of Area= base times height divided by 2.

first step you need to do is multiply 4.5 by 2 to get 9. then you have to divide 9 by the height. Then you will get the value of the height. Hope you understood!

Answer:

x=62

Step-by-step explanation:

The sum of x ,28, and 90 is 180 since it forms a straight line

x+28+90 = 180

Combine like terms

x+118 =180

Subtract 118 from each side

x+118-118 =180-118

x= 62

Answer:

Step-by-step explanation

x+28=90 degree(being perpendicular)

x=90-28

x=62

Answer:

77 boxes

Step-by-step explanation:

Step 1:

Lana's troop must sell 1000 boxes of cookies, but there are 13 girls in total. Supposing that each girl will sell an equal amount of boxes, we can simply divide:

[tex]1000[/tex]÷[tex]13\approx76.92[/tex] boxes.

Step 2:

However, it would seem unlikely that the girls would decide to sell fractions of a box of cookies. We should round...up or down?

If we round down, each girl will sell 76 boxes of cookies. Hmm... then they would'nt be able to sell a total of 1000 boxes of cookies! We need to round up.

Therefore, each girl should sell at least [tex]\fbox{77}[/tex] boxes.

I hope this helps! Let me know if you have any questions :)

Explanation:

Place a decimal point between the first two digits 3 and 7.

Now ask yourself how you can go from 3.7 back to the original value. Notice we can move the decimal point 6 spots to the right to go from 3.7 back to 3,700,000

Therefore, the exponent over the 10 is 6. The exponent is positive to mean we move the decimal point to the right. If we had a negative exponent, then we'd move left.

You can use a calculator to confirm that 3.7 * 10^6 = 3,700,000

Side notes:

3,700,000 = 3 million, 7 hundred thousand

3,700,000 = 3.7 million

Answer:

x = 4

Step-by-step explanation:

4x + 5 = 2x + 13

4x - 2x + 5 = 2x - 2x + 13

2x + 5 = 13

2x + 5 - 5 = 13 - 5

2x = 8

2x ÷ 2 = 8 ÷ 2

x = 4

[tex]4x+ 5 = 2x + 13[/tex]

[tex]\mathrm{Subtract\:}5\mathrm{\:from\:both\:sides}[/tex]

Answer:

K = 10

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin theta = opp/ hyp

sin K = 11 / 61

Taking the inverse sin of each side

sin ^-1 ( sin K) = sin ^-1 (11/61)

K =10.38885782

K = 10

Answer:

11 or exact is 10.8 ft.

Step-by-step explanation:

we do 2.7*4 to find the length of the actual car

since 1 inch is 4 feet in real life.

2.7 would be 2.7*4 feet in real life

2.7*4 = 10.8 which is rounded to the nearest foot, 11.

Answer:

10.8

Step-by-step explanation:

model: real life

1 inch : 4 ft

The model is 2.7 inches

Multiply by 2.7 inches

model: real life

1 *2.7  : 4 *2.7

2.7 in : 10.8 ft

Answer and Step-by-step explanation:

First, write down the equation.

9e + 4 = -5e + 14 + 13e

Combine like terms.

9e + 4 = 8e + 14

Subtract 4 and 14 from both sides of the equation.

e = 10

e = 10 is the answer.
