On August 20, 1989, in Cologne, West Germany, Said Aouita of Morocco also established a world record when he ran the 3000. m run in 7 minutes, 29.45 seconds. What was his average speed (in m/s) for the race? Remember to include your data, equation, and work when solving problem
PLS HURRY I HAVE TO TURN THUS IN!!!!!
Answer:
Average speed of Aouita = 6.68 meter per second.
Step-by-step explanation:
To create a world record Aouita ran a distance = 3000 m
He took the time to cover this distance = 7 minutes 29.45 seconds
= (7×60) + 29.45 seconds
= 449.45 seconds
Since, formula for the average speed is given by,
Average speed = [tex]\frac{\text{Total distance covered}}{\text{Total time taken}}[/tex]
Therefor, average speed of Aouita = [tex]\frac{3000}{449.45}[/tex]
= 6.675
≈ 6.68 meter per second
Average speed of Aouita was 6.68 meter per second.
Answer:
6.67 m/s
Step-by-step explanation:
7 * 60 = 420
420 + 29.45 = 449.45
V = 3000. / 449.45= 6.67 m/s
What is the slope and y-intercept of the line y - 2x = 8
Answer:
Slope is 2x and y-intercept is 8
Step-by-step explanation:
First you have to get y all by itself on the left side of the equal sign. To do that, you must add 2x on both sides. You will get: y=2x+8.
Answer:
Slope= 2
Y-intercept= (0,8)

Answer:
Step-by-step explanation:
(a)
well since they can lay 7 miles of track every day, the formula i make for the amount of track there is left to lay is:
L=196-Ld
where l is the length of track remaining, L is the length of track they can lay in one day and d is the number of days.
so we replace L for 7 and d for 17 and we get:
L=196-7x17
which works out to be 77 miles of track remaining to lay.
(b)
well since we want them to have 0 length of track remaining, and they can lay 7 miles of track a day, we can work out d. let's give the formula a bash to get:
d=196-l/L
we then replace l with 0 and L with 7 and get:
d=196/7
which works out to be 28. so it will take 28 days or 4 weeks for the railroad crew to lay 196 miles of track.
Write the equation in Point-Slope Form of a line that has a slope of 3/4 and passes through point (-4, -12).
Answer:
The equation in Point-slope form of a line that has a slope of 3/4 and passes through the point (-4, -12) is:
[tex]y+12=\frac{3}{4}\left(x+4\right)[/tex]
The graph of the equation line is also attached below.
Step-by-step explanation:
Given
Slope m = 3/4Point (-4, -12)To determine
We have to determine the equation in Point-Slope Form.
We know that the Point-slope form of a line equation is defined as
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where
[tex]m[/tex] is the slope of the line[tex]\left(x_1,\:\:y_1\right)[/tex] is the pointIn our case:
Slope m = 3/4(x₁, y₁) = (-4, -12)substituting the values m = 3/4 and the point (x₁, y₁) = (-4, -12) in the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-\left(-12\right)=\frac{3}{4}\left(x-\left(-4\right)\right)[/tex]
Apply rule: [tex]-\left(-a\right)=a[/tex]
[tex]y+12=\frac{3}{4}\left(x+4\right)[/tex]
Therefore, the equation in Point-slope form of a line that has a slope of 3/4 and passes through the point (-4, -12) is:
[tex]y+12=\frac{3}{4}\left(x+4\right)[/tex]
The graph of the equation line is also attached below.
According to her running log, Alexa averaged 4 Miles per week last month and 50%less this month. How much did she average this month?
Answer:
2 miles per week
Step-by-step explanation:
If she averaged 50% less this month, that means her average this month is half of 4.
Divide 4 by 2
4/2
= 2
So, she averaged 2 miles per week this month
3. Five more than a number is below 17. Use n
for the number.
Answer:
n + 5 = below 17
Step-by-step explanation:
Answer:
n+5<7
Step-by-step explanation:
n+5<7
This is just what I think the problem is asking. Since it asks for 5 more than a number(it doesn't specify what number), then it doesn't matter what number it is. It didn't say that the number is 17, which means that the equation is probably an unequality sentence.

Find the Area Of This Figure.
Answer:
42in
Step-by-step explanation:
First divide up the shape.
The bottom will cut off to form a 6x3 rectangle which will have an area of 18in. Next is the top portion which is a trapezoid. You can figure out the area two ways. You can divide it further into two triangles and a rectangle. Or you can use the trapezoid formula. In this case I feel like dividing it. So since the top is 2 inches the bases of the two side triangles must be 2 due to the bottom base of the whole shape being 6. (1/2*2*6)*2 = 12in. Lastly the center rectangle is 2*6 (got 6 from 9-3) which is also 12. So the top half added together 12+12 equals 24in. When adding both top and bottom portions (18+24) you get 42in.

Step-by-step explanation:
A consumer organization inspecting new cars found that many had appearance defects (dents, scratches, paint chips etc.). No car had more than three defects. Here is the probability distribution for the number of appearance defects in a new car. X: number of defects 0 1 2 3 P(x) 0.61 0.21 0.11 0.07 Find the expected number of appearance defects in a new car. Do not round.
Answer:
The expected number of appearance defects in a new car is 0.64.
Step-by-step explanation:
To find the expected number of appearance defects in a new car, we multiply each outcome by its probability.
We have that:
0.61 probability of 0 defects
0.21 probability of 1 defect
0.11 probability of 2 defects
0.07 probability of 3 defects
0.61*0 + 0.21*1 + 0.11*2 + 0.07*3 = 0.64
The expected number of appearance defects in a new car is 0.64.

What is the length of side s of the square shown below?
45
90°
A. 2-2
B. 2
C. 42
O D. v2
E. 1
O F. 4
Answer:
D. √2
Step-by-step explanation:
Solve for x by applying trigonometric ratio.
Reference angle = 45°
Hypotenuse = 2
Adjacent side = s
Thus:
Cos (45) = adj/hyp
Cos (45) = s/2
2×Cos(45) = s
2 × √2/2 = s (cos (45) = √2/2)
√2 = s
s = √2

Step-by-step explanation:
Please see image below. What is the value of X in the figure to the right? What is the measure of angle DGC in the figure to the right?
Answer:
x = 50
DGC: 130 degrees
Step-by-step explanation:
x and the angle next to the angle x-10 are vertical angles are equal, so that means the two angles that add up to 90 are x and x-10.
x + x - 10 = 90
2x - 10 = 90
2x = 100
x = 50
The measure of angle DGC is:
180 - x
180 - 50
130
