Answer:
The answer is below
Step-by-step explanation:
A student on the cross- county team runs 30 minutes a day as a part of her training. Write an equation to describe the relationship between the distance she runs in miles, D, and her running speed, in miles per hour, when she runs at a constant speed of 5.4miles per hour for m minutes, and then at b miles per hour for n minutes
Solution:
Given that the student runs for a total of 30 minutes per day. He runs at 5.4 miles per hour for m minutes, and then at b miles per hour for n minutes.
Hence:
m + n = 30
60 minute = 1 hour. Therefore, m minute = m/60 hour, n minute = n/60 hour.
The distance traveled is the product the speed in miles per hour and the time taken to cover the distance. Distance = speed * time
The total distance ran (D) is:
D = 5.4(m/60) + b(n/60)
Use parentheses to show two ways of grouping the numbers in 12 • 8 • 25. Tell which expression you think would be easier to simplify, and why. Then simplify the expression.
Step-by-step explanation:
First no. is 12
Second no. is 8
Third no. of 25
Way 1 of grouping the numbers,
(12×8)×25
We can use associative law of multiplication as follows :
(a×b)×c = a×(b×c)
(12×8)×25 = (96) × 25
= 2400
Way 2,
12×(8×25) = 12 × 200
= 2400
Way 2 is easier to simplify because when we multiply 8 and 25, we get 200. It is very easy to multiply any number with a number that have zeroes. As a result we easily get the answer i.e. 2400.

Answer:
C
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
-2.45 times 10 squared is -245 while square root of 93 is 9.643650761 so 6.387 is the smallest then square root of 93 then -2.45 times 10 squared.
What is the equation of the line that has a slope of -4 and goes through (-1,6)? O A. y+ 6 = -4(x + 1) OB. y+6= -4(x - 1) OC. y-6 = -4(x + 1) OD.y-6 = -4(x - 1)

You bought 5 chocolate bars and 8 blow pops for $23.25. Your sister bought 2 chocolate bars and 13 blow pops for $21.55. How much did each chocolate
bar cost? Each chocolate bar cost?
Answer:
Cost of each chocolate bar = $2.65
Cost of each blow pop = $1.25
Step-by-step explanation:
Let x = Cost of chocolate bar
y= Cost of blow pops
We can make system of equations and find value of x and y
You bought 5 chocolate bars and 8 blow pops for $23.25.[tex]5x+8y=23.25[/tex]
Your sister bought 2 chocolate bars and 13 blow pops for $21.55. [tex]2x+13y=21.55[/tex]
Let:
[tex]5x+8y=23.25--eq(1)\\2x+13y=--eq(2)[/tex]
Multiply eq(1) with 2 and eq(2) with 5 and subtract
[tex]10x+16y=46.5\\10x+65y=107.75\\- \ \ \ - \ \ \ \ \ \ - \\------\\-49y=-61.25\\y=\frac{-61.25}{-49} \\y=1.25[/tex]
So, value of y = 1.25
Putting value of y in eq(1) to find value of x
[tex]5x+8y=23.25\\5x+8(1.25)=23.25\\5x+10=23.25\\5x=23.25-10\\5x=13.25\\x=13.25/5\\x=2.65[/tex]
Value of x = 2.65
So, Cost of each chocolate bar = x = $2.65
Cost of each blow pop = y = $1.25
2 (x + 5) = } (x – 4)?

Answer:
X= -14
Step-by-step explanation:
So we can first simplify the equation
2x+10=x-4
Now just solve i normally
x+10=-4
x=-14
So x is -14

Consider the line y= -1/2x+5
What is the slope of a line parallel to this line?
What is the slope of a line perpendicular to this line?
Answer:
Step-by-step explanation:
For a line to be parallel, it needs to have same slope so the slope is -1/2 for parallel.
The slope for perpendicular is the negative reciprocal so 2.

8.314, 8.356, 8.475, 8.36, 8.43, 8.5
LESSER GREATER
ASAP PLS
Answer:
8.314, 8.356, 8.36, 8.43, 8.475, 8.5
^ This is the numbers from least to greatest, 8.314 being the least and 8.5 being the greatest.
Step-by-step explanation:
First, start off with the lowest number. You will see that each number starts with 8, so we go to the next number. You will now see three numbers having the number 3 in the second place. Now, we go to the next digit after that.
1 is less than 5 and 6, and 5 is less than 6.
This means that the 1 will go first, followed by the 5, then the 6.
Now we see that there are two numbers with a 4 in the second decimal place. The next number after that will now determine where it goes.
3 is less than 7, so that means 3 will come before 7.
The digit 5 is the greatest, so it will be at the end of the list.
