The correct option is d. 8 oz. can of juice is most convenient to meet this requirement.
First, let's convert 240 milliliters to ounces because the answer choices are in ounces.
1 milliliter is approximately equal to 0.0338 ounces.
So, 240 milliliters is approximately \( 240 \times 0.0338 \) ounces, which is about 8.112 ounces.
Now, let's examine the options:
a. 5 oz. can of juice: Not enough juice. It's less than the required 8.112 ounces.
b. 4 oz. can of juice: Not enough juice. It's less than the required 8.112 ounces.
c. 12 oz. can of juice: More than enough juice. It's more than the required 8.112 ounces.
d. 8 oz. can of juice: Exactly the amount needed. It matches the required 8.112 ounces, which is the closest to the calculated amount of 8.112 ounces.
Therefore, the 8 oz. can of juice is the most convenient option to meet the requirement of having 240 milliliters of juice every 2 hours.
solve the equation by completing the square 5x(x+6)=-50
To solve the equation 5x(x+6) = -50 by completing the square, we first isolate the quadratic term and then add the square of half the coefficient of x to both sides of the equation. Taking the square root gives us the solution x = -3 + i and x = -3 - i.
Explanation:
To solve the equation by completing the square, we first need to isolate the quadratic term on one side of the equation. So, let's distribute the 5x to get 5x^2 + 30x = -50. Next, we move the constant term to the other side and divide the equation throughout by the leading coefficient to get x^2 + 6x + 10 = 0.
Now, we can complete the square by adding the square of half the coefficient of x (which is 3) to both sides of the equation. This gives us (x + 3)^2 + 10 - 9 = 0, which simplifies to (x + 3)^2 + 1 = 0.
Taking the square root of both sides, we get x + 3 = ±√(-1), which means x = -3 ± i. Hence, the solution to the equation is x = -3 + i and x = -3 - i.

A 25-foot streetlight casts a showdown 20feet long.If Melanie is standing at the end of the shadow casted by a 60. -foot tall building,how far is she from the building.
By setting up a proportion based on the similar triangles created by the streetlight and the building, we can find that Melanie is standing 48 feet away from the building.
To solve the problem of determining how far Melanie is standing from the building using the shadows, we can use similar triangles. We are given a 25-foot streetlight that casts a 20-foot shadow and a 60-foot tall building. The goal is to find the length of the shadow cast by the building, which will tell us how far Melanie is from the building.
By setting up a proportion based on the similar triangles, we have:
Height of the streetlight / Length of streetlight's shadow = Height of the building / Length of the building's shadow.25 feet / 20 feet = 60 feet / x feet.To find the value of x, we cross multiply:25x = 60 * 20.x = (60 * 20) / 25.x = 1200 / 25.x = 48 feet.Therefore, Melanie is standing 48 feet away from the building.

what is rounding and estimate 253,495 - 48,617=
Answer:
205000
Step-by-step explanation:
Given : 253,495 - 48,617
To Find : What is rounding and estimate
Solution:
To Estimate a difference by rounding.
1 ) Round each term that will be subtracted
2 )Subtract the rounded numbers
Round off of 253,495 = 253000
Round off of 48,617 = 48000
So, 253000 - 48000 = 205000
Hence The rounding and estimate 253,495 - 48,617= 205000
Tran drove his car at a constant speed of 55 mph.
Which is an equation for the distance Tran drove?
A. 55d=t
B. d=55t
C. t/d=55
D. 55/d=t
Plz help I think the answer is D am not sure.
The correct equation for the distance Tran drove at a constant speed of 55 mph is B. d = 55t.
In this equation:
"d" represents the distance in miles that Tran drove.
"t" represents the time in hours.
So, the distance "d" is equal to Tran's constant speed of 55 mph multiplied by the time "t" in hours, which is why the equation is written as d = 55t.
Option D is not the correct equation because it has the variables and constants in the wrong order.
The correct order is distance (d) on the left side of the equation, followed by the constant speed (55) and then the time (t) on the right side of the equation.

When sales representatives for a pharmaceutical company drive out of town meetings that require an overnight stay, they receive $175 for lodging plus $0.70 per mile driven. How many miles did Joe drive if his company reimbursed him $329 for an overnight trip?
Set up an equation that can be used to solve the problem. Solve the equation and determine the desired value.
Joe was given $329 for an overnight trip because he drove a distance of 220 miles
Word ProblemGiven Data
Amount rep receive = $175Added amount per mile driven = $0.70Reimbursed/Total = $329The Mathematical relation for this scenario is
Total amount = Amount Receive+ 0.7*Distance driven
let the distance driven be x
Substituting our given data into the relation we have
329= 175+ 0.7*x
329-175 = 0.7x
154 = 0.7x
divide both sides by 0.7
x = 154/0.7
x = 220miles

If you work for an hourly wage, your gross pay is a function of the number of hours that you work. Your hourly wage is $8 per hour. Assuming you work 40 hours per week, what is the practical domain and the practical range of the function? a. The practical domain is 0 through 8. The practical range is 0 through 32. b. The practical domain is 0 through 320. The practical range is 0 through 40. c. The practical domain is 0 through 40. The practical range is 0 through 320. d. The practical domain is 0 through 32. The practical range is 0 through 8.
Answer:
The correct option is C.
Step-by-step explanation:
It is given that gross pay is a function of the number of hours that you work.
Let y represents the gross pay and x represents the number of hours. So, the value of x and y can be negative.
Hourly wage = $8 per hour.
The weekly gross pay function is
[tex]y=8x[/tex] .... (1)
Domain is the set of inputs and ranges is the set of outputs.
It is given that you work 40 hours per week. It means the value of x lies between 0 to 40.
Domain = [0,8]
Substitute x=40 in equation (1), to find the gross pay when number of hours is 40.
[tex]y=8(40)=320[/tex]
Range = [0,320]
The practical domain is 0 through 40. The practical range is 0 through 320.
Therefore the correct option is C.
The practical domain for the function representing gross pay is the range of hours worked, 0 to 40 hours. The practical range is the corresponding gross pay, from $0 to $320, based on an $8 per hour wage for up to 40 hours of work. So correct answer is option C.
To determine the practical domain and range of the function that represents your gross pay based on an hourly wage of $8 per hour, we must consider the possible number of hours you can work in a week and the corresponding earnings. Given that you work 40 hours per week, the practical domain (which represents the number of hours worked) would be any value from 0 to 40 hours, since you cannot work negative hours and we're assuming a standard full-time workweek.
The practical range (which represents the gross pay) is calculated by multiplying the number of hours worked by the hourly wage. Therefore, the range would be 0 (if you work 0 hours) to $320 (if you work 40 hours), because 40 hours times $8 per hour equals $320.
So, the correct answer from the given options is Option C.
Practical domain: 0 through 40.
Practical range: 0 through 320.
