s=av/t where av= average speed and s= speed and t= time

The cheetah ran 960 meters in 30 seconds with an average speed of

36 m/s.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

We know, distance = speed×time or d = st.

Given, A cheetah runs with an average speed of 32 m/s for 30 seconds.

Here, s = 32 m/s and t = 30 seconds.

Therefore, d = 32×30 meters.

d = 960 meters.

Answer:

The diamond production is 2006 is expected to be 13.24 billion

Step-by-step explanation:

Here, we want to predict the diamond production is 2006

The equation to use is given in the question as;

f(x) = 0.39x + 10.9

Since x is the number of years after 2006, in this particular question, x will be 2006-2000 = 6

So f(6) = 0.39(6) + 10.9

f(6) = 2.34 + 10.9

f(6) = 13.24 billion

i solved using y2-y1/x2-x1

Answer:

1. slope= 7

2. slope= -3

3. slope= -2/3

Step-by-step explanation

you find slope by doing rise over run (how much you have to go up/down and left/right to get to the next point.

for the first one, to get from the bottom point to the top point, you have to rise 7, and go to the right 1, which makes 7/1, simplified to 1.

for the second one, you go to rise 6, and then go to the left 2, which makes 6/-2, it is negative because when you have to go left, it just means a negative slope. this simplifies to -3

for the third one, you rise 4 and go to the left 6 from the bottom point to the top point. this makes 4/-6, simplifies to -2/3/

Given:

Total number of students at Colfax Middle School = 270

Ratio of boys to girls is 5:4.

Total number of students at Winthrop Middle School = 180

Ratio of boys to girls is 4:5.

The two schools hold a dance and all students from both schools attend.

To find:

The fraction of the students at the dance are girls

Solution:

There are 270 students at Colfax Middle School, where the ratio of boys to girls is 5:4.

[tex]5+4=9[/tex]

Number of boys [tex]=270\times \dfrac{5}{9}=150[/tex]

Number of girls [tex]=270\times \dfrac{4}{9}=120[/tex]

There are 180 students at Winthrop Middle School, where the ratio of boys to girls is 4:5.

[tex]4+5=9[/tex]

Number of boys [tex]=180\times \dfrac{4}{9}=80[/tex]

Number of girls [tex]=180\times \dfrac{5}{9}=100[/tex]

Now,

Total number of students in both schools [tex]= 270+180[/tex]

                                                                [tex]= 450[/tex]

Total number of girls in both schools [tex]= 120+100[/tex]

                                                         [tex]= 220[/tex]

The fraction of the students at the dance are girls is

[tex]\text{Required fraction}=\dfrac{\text{Total number of girls in both schools}}{\text{Total number of students in both schools}}[/tex]

[tex]\text{Required fraction}=\dfrac{220}{450}[/tex]

[tex]\text{Required fraction}=\dfrac{22}{45}[/tex]

Therefore, the required fraction is [tex]\dfrac{22}{45}[/tex].                                

Answer:

The Whole

Step-by-step explanation: it is the whole because it is saying that there were 14 cars sold and that was 56% of whatever the whole is.

We want to find the slope of a line perpendicular to 15*x + 9*y = 189.

The slope of the line perpendicular to the given line is 9/15.

First, a general line written in the slope-intercept form is written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

And two lines are perpendicular if one has a slope that is equal to the inverse of the opposite of the other line's slope.

So, to find the slope of the line perpendicular to 15*x + 9*y = 189, first, we need to find the slope of this line.

To do it, we need to isolate y.

9y = -15x + 189

y = (-15/9)*x + 189/9

So the slope is -15/9

A perpendicular line to this must have a slope equal to the inverse of the opposite of this, so the slope of the perpendicular line is:

-(-9/15) = 9/15

The slope of the line perpendicular to the given line is 9/15.

Answer: 406

Step-by-step explanation:

Answer:

792

Step-by-step explanation:

The answer is 792 because, we know that there is 24 calories in each bar, so, when calculating total amount of, you wan to multiply that amount by however many bars there are. The reason you multiply is because(using this example) when you have a bar with 24 calories and another bar with the same amount, you just add the two calorie amounts together, or 24 + 24. Since you have 33 bars, you would do that 33 times, which is the same as 24 x 33. So if you calculate 24 x 33, you get 792. Another way to solve this is you can use the formula x=cb where x is the total amount of calories, c is the number of calories in one bar, and b is how many bars you have.
