Answer:
1. 1 cup of concentrate would use 7.5 cups of water.
2. 10 cups of concentrate would use 75 cups of water.
Step-by-step explanation:
Because 1/3 cup of concentrate is mixed with 2 1/2 cups of water, to find how much water one cup of concentrate would use, you would have to multiply both 1/3 and 2 1/2 (2.5) by 3. Then, you get 1 cup of concentrate equals 7 1/2 (7.5).
To find the answer to the next question, simply multiply by 10.

solve the system of equations using elimination.
X-Y=3
2x+2y=50
Answer:
abcdefg
Step-by-step explanation:
Answer:
x = 14
y = 11
Step-by-step explanation:
x - y = 3
2x + 2y = 50
multiplty x - y = 3 by two so we can get an equal value
2x - 2y = 6
2x + 2y = 50
-2y and 2y can be cancled out. That means we don't need to change any signs and we can add everything exept 2y and -2y becuase they will be cancled out.
4x = 56
Divide each side by 4 to leave x alone.
x = 14
Now that we know the x value, take one of the equations in the question and plug it in. I am going to use the equation x - y = 3 to make it easier.
14 - y = 3
-y = 3 - 14
-y = -11
y = 11
Now we know that y = 11.
I hope this helps!

Step-by-step explanation:
Graph the rational function f(x)=(3x-1)/(x-5)
To graph the rational function f(x) = (3x - 1) / (x - 5), follow these steps. Find the vertical asymptote(s) by setting the denominator equal to zero and solving for x.
x - 5 = 0
x = 5
The vertical asymptote of the function is x = 5.
Step 1: Find the horizontal asymptote by comparing the degrees of the numerator and denominator polynomials. Since the degree of the numerator (3x - 1) is 1, and the degree of the denominator (x - 5) is also 1, the horizontal asymptote is given by the ratio of the leading coefficients:
Horizontal asymptote: y = 3/1
Horizontal asymptote: y = 3
Step 2: Find the x-intercept by setting the numerator equal to zero and solving for x:
3x - 1 = 0
3x = 1
x = 1/3
The x-intercept is (1/3, 0).
Step 3: Find the y-intercept by setting x to zero and evaluating the function:
f(0) = (3 * 0 - 1) / (0 - 5)
f(0) = -1 / -5
f(0) = 1/5
The y-intercept is (0, 1/5).
Step 4: Find additional points to sketch the graph. Choose some x-values around the vertical asymptote (x = 5) and calculate the corresponding y-values. For example, you can use x = 4, x = 6, and x = 8.
x = 4:
f(4) = (3 * 4 - 1) / (4 - 5)
= 11 / -1
= -11
x = 6:
f(6) = (3 * 6 - 1) / (6 - 5)
= 17 / 1
= 17
x = 8:
f(8) = (3 * 8 - 1) / (8 - 5)
= 23 / 3
≈ 7.67
Step 5: Plot the points obtained from Steps 2 to 5 and draw the graph. The graph should approach the horizontal asymptote (y = 3) as it approaches the vertical asymptote (x = 5).
The graph of the rational function f(x) = (3x - 1) / (x - 5) should look like this:

A bag of pennies weighs 5.1 kilogram. Each penny weighs 2.5 grams. About how many pennies are in the bag?
A. 20
B. 200
C. 2,000
D. 20,000
Answer:2K
Step-by-step explanation:since one kilogram is 1,000 grams and there 5.1 kL it’s 5,100 grams so about 2,000 pennies
Answer:
C, 2000
Step-by-step explanation:
First convert kilo grams into grams, there are 1000 grams in 1 kilogram, the prefix "kilo" means thousand. if you multiply 5.1 times 1000 you will get 5100 grams in the bag. Divide this by the weight of the penny, 2.5, to get 204. The question asks "About how many pennies are in the bag?" so we know to round to the closest answer being c.

How do i measure the diameter of a circle?
Answer:
Step-by-step explanation:
If you know the radius of the circle, double it to get the diameter. The radius is the distance from the center of the circle to its edge. If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. If you know the circumference of the circle, divide it by π to get the diameter
hope that helps!
The steps to measure the diameter of a circle is shown below.
You must perform the following steps in order to determine a circle's diameter:
1. Lay a ruler or measuring tape over the circle's centre, making sure it goes through the widest point.
2. Check to make sure the ruler or measuring tape is straight and correctly positioned.
3. Check the measurement at the intersection of the circle's two sides using the ruler or measuring tape.
4. Make a note of the measurement you took.
5. To find the circle's diameter, multiply the measurement you took by two.
The piece of a straight line that connects two places on the circumference and travels through the centre of a circle is known as the diameter.
