Answer:
7mph and he stayed the same
Step-by-step explanation:
Larry's average speed from hour 2 to hour 4 and from hour 4 to hour 7 is the same, 7 mi/hr, he maintained a constant speed throughout this period.
Given that Larry recorded his time as he ran
Time elapsed(hr) Distance run(mi)
2 13.5
4 27.5
7 48.5
We need to calculate his average speed,
To calculate Larry's average speed, we need to divide the total distance he ran by the time elapsed.
Let's calculate his average speed from hour 2 to hour 4 and from hour 4 to hour 7:
Average speed from hour 2 to hour 4:
Distance covered = 27.5 mi - 13.5 mi = 14 mi
Time elapsed = 4 hr - 2 hr = 2 hr
Average speed = Distance covered / Time elapsed = 14 mi / 2 hr = 7 mi/hr
Therefore, Larry's average speed from hour 2 to hour 4 was 7 miles per hour.
Average speed from hour 4 to hour 7:
Distance covered = 48.5 mi - 27.5 mi = 21 mi
Time elapsed = 7 hr - 4 hr = 3 hr
Average speed = Distance covered / Time elapsed = 21 mi / 3 hr = 7 mi/hr
Therefore, Larry's average speed from hour 4 to hour 7 was also 7 miles per hour.
Since Larry's average speed from hour 2 to hour 4 and from hour 4 to hour 7 is the same (7 mi/hr), he maintained a constant speed throughout this period. He neither sped up nor slowed down.

Answer:
C. x = 8
Step-by-step explanation:
We know that x · x · x is equal to 512. We know it cannot be negative because then the 512 would be negative. -2 x -2 x -2 is -8. -2 x -2 is 4. We know it cannot be B x = -6 or D. x = -8.
Let's multiply 6 x 6 x 6.
36 x 6 = 216.
Let's multiply 8 x 8 x 8.
64 x 8 = 512
The answer would be C. x = 8.

A factory needs to produce 1,800 jars of peanut butter on a certain day.
They start production at 8:30 A.M. By 10:30 A.M., they have produced 600 jars of peanut butter. At what time will they complete the total number of jars that they need to produce?
Answer:
2:30 am
Step-by-step explanation:
There is a 2 hour gap in between 8:30 and 10:30 and since they only made 600 jars throughout those 2 hrs you can divide 600 by 2 so you can fins out how many jars they make every hr.
Or you can multiply 600 and 2 to find out how much they make within the next 2 hrs.
600 * 2 = 1200
1200 jars were made at 12:30
1200 * 2 = 1800
1800 jars were made at 2:30
There are two hours between 8:30 A.M. and 10:30 A.M. If they make 600 jars of peanut butter per two hours, then they will make 300 jars per hour. 1800 divided by 6 is 300, so they need six hours to make 1800 jars of peanut butter. So, if they begin production at 8:30 A.M., the factory will have produced 1800 at 4:30 P.M.

What is the prime factorization of 72? (1 point)
O 1x2x4x9
O 22x32
0 22x33
O 2x32
Answer:
2³×3²
Step-by-step explanation;
TO FIND A PRIME FACTORIZATION OF A NUMBER YOU FIRST NEED TO KNOW PRIME NUMBERS ARE;Prime Numbers are numbers which which have only two factors the number itself and one
Examples of Prime Numbers are;
2,3,5,7,11,13,17,19,23,29,etc
To Find The Prime Factorization Of The Number 72 you'll need to follow this;
72=2×36(we have the number 36 because when it's multiplied by 2 the product is 72 and 36 is not a prime number so it has to be broken down but since 2 is a prime number you leave it as it is)
72=2×2×18(we have 2×18 because because it's give us the product of 36 when multiplied so now that we have a second prime number(2) we will have to continue to break down the number 18)
72=2×2×2×9( We again have two another 2 and 9 here because when multiplied by each other its product is 18 so as we can see 9 is not a prime number so we have to break it down but the 2 is a prime number so we let it be)
72=2×2×2×3×3( As we can see here, 3 and 3 is a prime number so nothing happens to it so we have broken the non-prime numbers down so now we have all the numbers as Prime Numbers)
So; 72=2×2×2×3×3
So we are going to count the twos and threes so as you can see we have three twos and we have two threes. Which makes our final answer;
2³×3²
So The Prime Factorization of 72 is; 2³×3²

Let the measure of the other interior angle = M
The exterior angle is equal to the sum of the interior angles in a given triangle.
An exterior angle of a triangle has a measure of 80°, and one of the remote interior angles has a measure of 20°.
This means,
M + 20 = 80
Solve for M.
M + 20 = 80
Subtract 20 on both sides.
M = 80 - 20
M = 60
Thus,
The measure of the other remote interior angle is 60°.

Answer:
y= 3/2x+ 360
Step-by-step explanation:
3/2 is the slope
360 is the b (y intercept)
Answer:
slope m = -60
equation y = -60x + 360
Step-by-step explanation:
to find slope use two points given
(x1, y1) = (6, 0)
(x2, y2) = (0, 360)
m = (360-0) / (0-6) = -60
equation y = mx + b
b is the y intercept at (0,360), b= 360
y = -60x + 360
What is an equation of the line that passes through the points (4,−1) and (8, 5)? Put your answer in fully reduced form.
HELP PLS
Answer:
y=2/3x-7
Step-by-step explanation:
The slope intercept formula is
y=mx+b
(m) is the slope (rate of change)
(b) is the y intercept (where the line crosses the y axis [vertical])
We need to find the slope and the y intercept. First we will find the slope.
The formula for slope is y1-y2/x1-x2
In and ordered pair the first value is the (x) and the second is the (y).
(x, y)
We take the (y) of one of the given points and subtract the (y) of the second given point, then divide it by the (x) of one of the given points and the (x) of the other given point.
5-(-1)/8-4
Simplify.
5-(-1) =5+1= 6
8-4=4
6/4 Simplify
3/2 is our slope.
Now we apply out new slope into our y=mx+b
y=3/2x+b
Now we need to find the (b) which is the y intercept.
To do this we need to use one of our given points, you can choose either but for this I'll use (4, -1).
In this ordered pair 4 is the (x) and -1 is the (y)
So replace (y) with -1 and (x) with 4
-1=3/2(4)+b
Now solve as usual.
-1=6+b
subtract 6 from each side
-7=b
b=-7
Put our (m) and (b) into our formula.
y=2/3x-7 is our equation.
