In a relay race, each runner completes the circuit 9 seconds faster than the previous one. If the first athlete runs his lap in 4 minutes 37 seconds, how many minutes does it take in total for the team of 8 competitors to finish the race? Give your answer correct to the nearest minute. [Answer format: integer, no units]
Answer:
31 minutes
Step-by-step explanation:
Here, we have 8 competitors with the previous runner outrunning the present by 9 seconds
1st runner time = 4 minutes 37 seconds
2nd runner time = 4 minutes 37 seconds - 9 seconds = 4 minutes 28 seconds
3rd runner time = 4 minutes 28 seconds - 9 seconds = 4 minutes 19 seconds
4th runner time = 4 minutes 19 seconds - 9 seconds = 4 minutes 10 seconds
5th runner time = 4 minutes 10 seconds - 9 seconds = 4 minutes 1 second
6th runner time s= 4 minutes 1 second - 9 seconds = 3 minutes 52 seconds
7th runner time = 3 minutes 52 seconds - 9 seconds = 3 minutes 43 seconds
8th runner time = 3 minutes 43 seconds - 9 seconds = 3 minutes 34 seconds
The total time is the addition of all the times
For clarity sake, we shall be adding all the minutes together and all the seconds together;
That will be ;
(4 * 6) + 3 minutes + ( 34 + 43 + 52 + 1 + 10 + 19 + 28 + 37)
= 27 minutes + 224 seconds
We need to convert 224 seconds to minutes
Since 60 seconds make one minute; we have
224 - 60(3) = 3 minutes and 44 seconds
Let’s add this to the minutes we had before
That would be;
27 minutes + 3 minutes + 44 seconds
= 30 minutes 44 seconds
since 44 seconds is greater than 1/2 minute (30 seconds), we can approximate it to 1 minute
So the total time is 30 minutes + 1 minute = 31 minutes

Find three consecutive integers such that when three times the third is increased by the first, the result is 8 less than five times the second.
Answer:
9, 10 and 11Step-by-step explanation:
x - the smallest of three consecutive integers (the first)
x+1 - the next of three consecutive integers (the second)
x+2 - the last of three consecutive integers (the third)
3(x+2) - three times the third integer
3(x+2)+x - three times the third increased by the first
5(x+1) - five times the second tnteger
5(x+1)-8 - 8 less than five times the second
3(x + 2) + x = 5(x + 1) - 8
3x + 6 + x = 5x + 5 - 8
4x + 6 = 5x - 3
-4x -4x
6 = x - 3
x = 9
x+1 = 10
x+2 = 11
Check: 3×11+9 = 33+9 = 42, 5×10-8=50-8 = 42

Which of the following equations produces a linear function?
A y=x?
B = 2x + 3
C y = |x|
D y=2x2 + 3x - 2
Answer:
a, b, and c
Step-by-step explanation:
all of them are in the form y=mx+b except for c, which does not have a constant slope throughout the entire line, it will be decreasing or negative until 0, and then increasing or positive after 0, so the slopes would not be the same.

Answer:
x=15
Step-by-step explanation:
4 I x-5 I +20 = 60 Distribute the 4
4x - 20 + 20 = 60 Combine like terms :
4x - 0 = 60
4x = 60 Divide:
x = 15
Check : 4 I 15 - 5 I + 20 = 60
4 I10I +20 = 60
40 + 20 = 60
60 = 60 ✔
Hope this helps :)
Answer:
x = 15Step-by-step explanation:
so simplify the first half of the equation
4x-20+20 = 60
combine like terms
4x = 60
divide both sides by 4
x = 15

someone help me with this please
Answer:
b= -8
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable. my answer is -8 but just multiply 5 by -8. and solve
-14+6b+7-2b=1+5b
-7+4b=1+5b
-1 -1
-8+4b=5b

A Pattern has 5 blue triangles to every 80
yellow triangles, what is the ratio of blue
triangles to all triangles?
Answer:
5:80, there are only 2 numbers
Step-by-step explanation:
The ratio of blue triangles to all triangles is 1 : 17.
What is mean by Ratio?A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.
Given that;
A Pattern has 5 blue triangles to every 80 yellow triangles.
Here, Number of blue triangles = 5
Number of all triangles = 5 + 80
= 85
Thus, The ratio of blue triangles to all triangles is,
⇒ Number of blue triangles : Number of all triangles
⇒ 5 : 85
⇒ 1 : 17

Rectangle QUAD has coordinates Q(0,0), U(0,3), A(7,3), and D(7,0). Q'U'A'D' is the image of QUAD after a dilation with center (0,0) and scale factor 6. What are the coordinates of point U '?
Answer:
22
Step-by-step explanation:
After dilation with center (0,0) and scale factor 6 new coordinates of point U are ( 0, 18).
What is dilation?" Dilation is defined as to resize the given geometrical shape with given scale factor."
Formula used
Scale factor
= (Dimensions of new shape) ÷ (Dimensions of original shape)
According to the question,
Given rectangle QUAD,
Coordinates of Q(0,0)
Coordinates of U(0,3)
Coordinates of A(7,3)
Coordinates of D(7,0)
Q'U'A'D' is the image of QUAD after a dilation with center (0,0) and scale factor 6.
New Coordinates of Q'(0,0)
New Coordinates of U'(0,18)
New Coordinates of A'(42,18)
New Coordinates of D'(42,0)
Hence, after dilation with center (0,0) and scale factor 6 new coordinates of point U are ( 0, 18).

probability that 12/a > a?
A. 12/19
B. 3/5

It is estimated that the distance traveled by each volunteer driver at the Huntington VA Medical Center is normally distributed with a mean of 50 thousand miles and a standard deviation of 12 thousand miles each year. What percentage of drivers can be expected to travel either below 30 or above 60 thousand miles in a year?
Answer: 25.08%
Step-by-step explanation:
Given: Distance traveled by each volunteer driver is normally distributed.
Mean ([tex]\mu[/tex]) = 50 thousand miles
standard deviation ([tex]\sigma[/tex])= 12 thousand miles
Let X = distance traveled by each volunteer driver
Required probability : [tex]P(X<30)+P(X>60)[/tex]
[tex]=P(\dfrac{X-\mu}{\sigma}<\dfrac{30-50}{12})+P(\dfrac{X-\mu}{\sigma}>\dfrac{60-50}{12})\\\\=P(z<-1.67)+P(z>0.83)\ \ \ [z=\dfrac{X-\mu}{\sigma}]\\\\= (1-P(z<1.67))+(1-P(z<0.83)\ \ \ [P(Z<-z)=1-P(Z<z)=P(Z>z)]\\\\= 2- P(z<1.67)-P(z<0.83)\\\\= 2- 0.9525-0.7967=0.2508\ \ [\text{By p-value table}][/tex]
Hence, percentage of drivers can be expected to travel either below 30 or above 60 thousand miles in a year = 25.08%
