In the chemistry lab an experiment requires 500ml of one ingredient to be mixed with 1,000 ml of another. How many liters is the solution
After mixing 500 ml with 1,000 ml, the total volume of the solution is 1.5 liters.
Explanation:To find out how many liters the solution is after mixing 500 ml with 1,000 ml, you simply add the volumes together and convert to liters. First, you have a total volume of 500 ml + 1,000 ml = 1,500 ml. Now, notice that you are going from a smaller unit (milliliters) to a larger unit (liters). Since there are 1,000 milliliters in a liter, you will need to divide by 1,000:
1,500 ml ÷ 1,000 = 1.5 liters.
Therefore, the solution will have a total volume of 1.5 liters.

Chuy wants to buy a new television. The television costs $1,350. Chuy decides to save the same amount of money each week, for 27 weeks. After 8 weeks Chuy saved $440. Which of the following conclusions can you make about Chuy's plan?
a. Chuy has a good plan and will have exactly $1,350 saved at the end of 27 weeks.
b. Chuy must increase the amount he saves each week in order to meet his goal at the end of 27 weeks.
c. Chuy will save more than he needs and will meet his goal in less than 27 weeks.
d. There is not enough information given to make a conclusion about Chuy's plan.
Answer:
Option C. is correct.
Step-by-step explanation:
Chuy needs $1,350 to buy a new television.
he decides to save the same amount of money each week for 27 weeks.
In 8 weeks Chuy saved = $440
In 1 week Chuy saved $440 ÷ 8 = $43.00
Therfore, in 27 weeks Chuy can save = 43.00 × 27 = $1485.00
Chuy can save $1485.00 in 27 weeks that is more than he needs.
So Option c. would be correct Chuy will save more than he needs and will meet his goal in less than 27 weeks.
What is the value of the function at x=−2?
y=−4
y = 0
y = 2
y = 3
Answer:
Option D.
Step-by-step explanation:
If the graph of a function f(x) passes through the point (a,b), then the value of the function f(x) is b at x=a.
[tex]f(a)=b[/tex]
[tex]y=b[/tex]
The graph of a function is given.
We need to find the value of function at x=-2.
From the given graph it is clear that the graph is passes through the point (-2,3).
It means the value of function is 3 at x=-2.
[tex]y=3[/tex]
Therefore, the correct option is D.
How many 5 pound bags of apples can be made from 400 apples each weighing 1/4 pound?
Answer:
You can make 20 - 5 pound bags
Step-by-step explanation:
You first find the number of total pounds that the 400 applying ratios :
400 apples * ¼ pound / 1 apple = 100 pounds by simplifying units
Then we find the number of bags as:
100 pounds* (1 bag/5 pounds ) = 20 bags by simplifying units
So the final answer is 20 bags for this problems by using ratios

Two classrooms are sharing seven packages of unit cubes if the packages are split evenly how many packages with each classroom receive
Find the value of x. Then find the measure of each labeled angle
Answer:
x=107
[tex]x-34=107-34=73[/tex]
Step-by-step explanation:
Sum of angles in a quadrilateral is 360 degree
right angle is 90 degree
[tex]90 +90+x+x-34= 360[/tex]
[tex]180+x+x-34=360[/tex]
subtract 180 from both sides
[tex]x+x-34=180[/tex]
[tex]2x-34=180[/tex]
add 34 on both sides
[tex]2x=214[/tex]
divide by 2 on both sides
x=107
[tex]x-34=107-34=73[/tex]

Find the dimensions of a right circular cylindrical can with both a top and a bottom that holds 5832 cubic cm and is constructed with the least amount of material possible.
The dimensions of a right circular cylindrical can that holds 5832 cubic cm and uses the least amount of material are a radius of approximately 10.614 cm and a height of approximately 16.526 cm.
Explanation:The question asks for the dimensions of a right circular cylindrical can that holds 5832 cubic cm of liquid and is designed to use the least amount of material. This scenario fits into the realm of mathematical optimization. Here, we’re being asked to identify dimensions that minimize the surface area of the cylinder while holding a fixed volume. This kind of problem is typically addressed using calculus.
The volume V of a cylinder is given by the formula V = πr²h where r is the cylinder radius and h is the cylinder height. The surface area A of a cylinder closed at both ends is given by A = 2πrh + 2πr².
From the volume equation, we can express h in terms of V and r, h = V/πr². Substituting this into the surface area equation yields: A = 2πr(V/πr²) + 2πr² = 2V/r + 2πr².
To find the radius that minimizes the surface area, we would set the derivative of the surface area with respect to r equal to zero and solve for r. After these calculations, we find that r = (V/(2π))^(1/3). For V = 5832 cubic cm, this yields r ≈ 10.614 cm.
Substitute r ≈ 10.614 cm back into the equation h = V/πr² to find h ≈ 16.526 cm. So, the dimensions of the can that minimizes the material used are radius 10.614 cm and height 16.526 cm.

To find the dimensions of the cylindrical can that holds a specific volume and is made from the least material, utilize the volume and surface area formulas for a cylinder. Using calculus, find the radius that minimizes the surface area, then find the corresponding height.
Explanation:This problem is a classic calculus optimization problem. The volume of the cylindrical can is given by the formula V = πr²h, where r is the radius and h is the height of the cylinder. To minimize the amount of material used in constructing the can, we need to minimize the surface area, given by the formula [tex]A = 2\pi rh + 2\pi r^2[/tex] (which includes both top and bottom of the can).
From the volume formula, we can express h as h = V/πr² = 5832/πr². Substituting this value into the surface area equation, we get A = [tex]2\pi r(5832/\pi r^2) + 2\pi r^2 = 11664/r + 2\pi r^2.[/tex] Differentiating this equation with respect to r and setting the derivative equal to zero, will provide the radius that minimizes the material used. The height can be obtained by substituting this radius value back into the equation h = 5832/πr².
