Step-by-step explanation:
Please inform me if you were incorrect.
You are correct. The 3 answers are B, C, and D
The notation [tex]m > 0[/tex] means that m is any positive number which accounts for the 1, 2, and 3.
Choice A is not a possible answer because [tex]m > 0[/tex] would update to [tex]0 > 0[/tex] which is false. Zero is not bigger than itself. No number is bigger than itself.
Choice E is also false because [tex]-1 > 0[/tex] is false. Anything negative is always smaller than zero.
If you wanted, you can use a number line to visually verify the answers.

let x equal the price of the medium drink
let y equal the price of the large popcorn
let’s start by creating an equation for the couple
they bought 2 drinks and 1 popcorn for 13.85$
so, 2x+1y=13.85
let’s make an equation for the family
they bought 3 drinks and 2 popcorns for 23.90$
so, 3x+2y=23.90
let’s solve for y using the COUPLE equation
minus 2x from the right to get 1y=-2x+13.85
1y is the same as y, the the equation for the couple is y=-2x+13.85
put this y value into the y value for the FAMILY equation
3x+2(-2x+13.85)=23.90
distribute the 2 to get 3x-4x+27.70=23.90
combine 3x and -4x to get -1x+27.70=23.90
minus 27.70 from both sides to get the following:
-1x=-3.8
multiple both sides by -1 to get x=3.8
the price of one drink is 3.8$
lastly, let’s figure out the price of the popcorn.
replace the x value in the COUPLE equation with the 3.8
2(3.8)+1y=13.85
multiply 2 and 3.8 to get 7.6
7.6+1y=13.85
minus the 7.6 to get 1y=13.85-7.6
reduce the equation to get y=6.25
so, the price of one drink is 3.80$ and one popcorn is 6.25$
hope this helped!!

A rabbit's fur grows at the rate of 5 over 2 inches per month.
How many months will it take the rabbit's fur to grow 15 over 4 inches?
Explain your answer using expressions and words.
Answers
Growth rate = 5/2 inches per month
The fur length after y months:
Fur length = 5/2 × y
Therefore, to have a fur length of 15/4 inches :
15/4 = 5/2 × y
3.75 = 2.5y
Divide both sides by 2.5 to isolate y
3.75/2.5 = y
1.5 = y
it will take a month and half to have a fur of 15/4 inch length
Answer:
1.5 months
Step-by-step explanation:
First, make [tex]\frac{5}{2}[/tex] so it has a common demoninator as [tex]\frac{15}{4}[/tex].
We need the demoninator to be the same so we can multiply [tex]\frac{5}{2}[/tex] by 2 to make it [tex]\frac{10}{4}[/tex].
So, a rabbit's ear grows [tex]\frac{10}{4}[/tex] of an inch in a month.
To find how many months, it will take, we have to divide [tex]\frac{15}{4}[/tex] by [tex]\frac{10}{4}[/tex].
To divide fractions, we can multiply with the reciprocal.
So, [tex]\frac{15}{4}[/tex] * [tex]\frac{4}{10}[/tex] is [tex]\frac{60}{40}[/tex] which reduces to [tex]\frac{6}{4}[/tex] which, in decimal form is equal to 1.5 months.

give the width of the lawnmower is 2.5 feet and the length of the rope is 25 feet, calculate the radius (R) of the pole that will produce a perfect lawn
Answers
Answer:
The radius is 0.398 feet to produce a perfect lawn for the lawnmower.
It is given that the width of the lawnmower is 2.5 feet and the length of the rope is 25 feet.
It is required to calculate the radius (R) of the pole that will produce a perfect lawn.
What is a circle?
It is defined as the combination of points that and every point has an equal distance from a fixed point ( called the center of a circle).
We have,
Width of the lawnmower = 2.5 feet
Length of the rope = 25 feet
For the perfectly mowed lawn, it means the lawnmower width which is 2.5 feet must wrap the pole with radius R, mathematically:
The perimeter of the pole = width of the lawnmower
2πR = 2.5
R = 0.398 Feet ( π = 3.14 )
Thus, the radius is 0.398 feet to produce a perfect lawn for the lawnmower.

Radius = Diameter / 2
Radius = 8 / 2
Radius = 4 cm
[tex]V = \pi (4^2)h[/tex]

Math Question In image.Please help me. Due Today
Answers
Answer:
See below
Step-by-step explanation:
If the diameter is doubled, the circumference is doubled. It is shown here:
18 * 3.14 = 56.52
36 (doubled diameter) * 3.14 = 113.04
If the circumference with the doubled diameter divided by the circumference of the original diameter comes out as 2, then it is proven that doubling the diameter doubles the circumference.
113.04/56.52 = 2.
The image for the rest is attached.
Answer:
Step-by-step explanation:
The Radius is (1/2) of the diameter, so to get the diameter we will multiply the radius by 2.
1. 9*2=18in
The we multiply the diameter by [tex]\pi[/tex] to get the cicumference. We know to do this because the equation of the circumference is C=[tex]\pi[/tex]d or C=2[tex]\pi[/tex]r. (p.s [tex]\pi[/tex]=3.1415926)
2. 18in*(3.1415926)=56.5487in
3. If the diameter is doubled the circumference is also doubled. We know this because of the equation C=[tex]\pi[/tex]d. The circumference is dependant upon the diameter and grows (or shrinks) with it.

Answer:
6: We already know the diamer, which is 18, and the radius which is half of 18. So 18 gets multiplied by PI (In this case 3.14) 3.14*18=56.52, or 56.5. Then we divide it by 2 (Cause it's a half circle.) which is 28.25.
7: 20*3.14=62.8/2=31.4
8: 8*3.14=25.12/2=12.56
(Because this time we didn't know the diameter, but 4+4=8.)

Charmaine received a $80 gift card for a coffee store. She used it in buying some coffee that cost $7.96 per pound. After buying the coffee, she had $32.24 left on her card. How many pounds of coffee did she buy?
Answers
Step-by-step explanation:
Algebraic Expression
Step 1 :- Make an equation
⇒ 7.96p + 32.24 = 80
Step 2:- Calculate for the value of variable
⇒ 7.96p + 32.24 = 80
Substract 32.24 from both sides
⇒7.96p + 32.24 - 32.24 = 80 - 32.24
Calculate
⇒7.96p = 47.76
Divide both sides by 7.96
⇒7.96p/7.96 = 47.76/7.96
Divide
⇒p = 6
Therefore, she bought 6 pounds of coffee

The United States Postal Service delivers about 2^8 ⋅ 5^2 pieces of mail each second. There are 2^8⋅3^4⋅5^2 seconds in 6 days. How many pieces of mail does the United States Postal Service deliver in 6 days? Write your answer as an expression involving three powers.
Key: ^ means the number that comes after is an exponent. For example: 4^9, 4 is the base and 9 is the exponent.

The total number of pieces delivered in 6 days is the number delivered each second (28.52) times the number of seconds in 6 days (28 34.52). This gives:
