Answer: 18
Step-by-step explanation:
The ratio of small to medium lemonades is 3 to 2. The ratio of medium to large lemonades is 3 to 2. Multiply 3/2 by 3/2 and you get 9/4. 9/4 is the amount of small lemonades needed for ONE large serving. Since you need the answer for EIGHT large servings, multiply 9/4 by 8 and you get 18, which is your answer.

Step-by-step explanation:
The new number, 200, is 400 less than the original number. What is the approximate percent change?
The percent change is approximately 0.6%.
The percent change is approximately 1.5%.
The percent change is approximately 66%.
The percent change is approximately 150%.
Answer:
66% is the approximate percentage change
Step-by-step explanation:
The original number is 600 and the new number is 200.
200 is a third of 600 which is approximately 66 percent.
Hence, The percent change is approximately 66% is the correct answer.
(Note): A way to remember percent of change is (old number - new number) divided by the old number
Find the cost price in each of the following:
a. selling price $120, profit 20%.
b. selling price $289, loss 15%.
Step-by-step explanation:
a.120÷100×20
profit=24
=24+120
=144
b.289÷100×15
=43.35
289-43.35
=245.65
The length of a rectangular book is 2 times its width. The perimeter of the book is 42 inches. Write a system of
equations to represent the dimensions of the book then find the length and width.
Answer:
Mark me as brainlist
Step-by-step explanation:
P = Perimeter
L = Length
W = Width
Perimeter of rectangle = L + L + W + W
or P = 2L + 2W
You know:
P = 36 inches
L = 2W [length is(=) 2 times it's width]
W = ?
P = 2L + 2W
Substitute/plug in what you know, plug in 2W for L since L = 2W
36 = 2(2W) + 2W Simplify
36 = 4W + 2W
36 = 6W Divide 6 on both sides
6 = W Now that you know the width, you can find the length:
L = 2W
L = 2(6)
L = 12
L = 12 in
W = 6 in
PROOF
P = 2(12) + 2(6)
P = 24 + 12
P = 36

A small start-up skateboard company projects that the cost per month of manufacturing x skateboards will be C(x)=30x+600, and the revenue per month from selling x skateboards will be r(x)=−x2+80x. Given that profit is revenue minus cost, for what value(s) of x will the company break even or make a profit?
9514 1404 393
Answer:
20 ≤ x ≤ 30
Step-by-step explanation:
The profit function is ...
profit = revenue - cost
= (-x^2 +80x) -(30x +600)
= -x^2 +50x -600
= -(x -20)(x -30)
The profit function will be positive where the signs of the factors are different: for x-values between 20 and 30. The profit function will be zero for x=20 and x=30.
The company will break even or make a profit for values of x that satisfy ...
20 ≤ x ≤ 30
A scientist needs 80 liters of a 30% solution of alcohol. She has a 20% solution and a 60% solution available.
How
many liters of the 20% solution and how many liters of the 60% solution should she mix to make the 30% solution
Answer:
60% answer for get 80 liters of 30% arrangement. 80x liters of 60% arrangement contains corrosive of 0.6(80x) liters. 80 liters of 30% arrangement contains corrosive of 800.3=24 liters

Pls help I'm dying ;)
Answer:
1) Subtract x on both sides to get
y = -x + 3
2) Subtract x on both sides to get -3y = -x + 12, then divide by -3 on both sides to get y = 1/3 x - 4
3) Subtract 5x on both sides to get 2y = -5x + 10, then divide by 2 on both sides to get
y = -5/2 x + 5
4) If I'm not mistaken, y = 6x + 1/3 is already in slope-intercept form (y=mx+b).
5)
[tex]y = \frac{1}{x} x - 15[/tex]
This is also in slope-intercept form⤴⤴⤴ It's just going to have a slope of 0, meaning it will be a horizontal line that passes through the y-axis at -15.
Sorry if it's wrong. Hope it helps though :)
Answer simple probability question for 50 points! Problem is attached, first person to answer gets 50 points. Make sure to answer A and B. Good Luck!!
[a] See attached
- Her chance of making it is 1/3, 1 - 1/3 = 2/3, so her chance of missing is 2/3
[b] 1/2 or one half
First chances (hit and hit): 1/4 * 1/3 = 1/12
Second changes (hit and miss): 1/4 * 2/3 = 2/12
Third chances (miss and hit): 3/4 * 1/3 = 3/12
(when multiplying fractions you multiply across)
Adding all chances together: 1/12 + 2/12 + 3/12 = 6/12 = 1/2

A group of students made the following measurements for the width of a block of wood.6.52 cm, 6.49 cm 6.51 cm, 6.52 cm and 6.50 cm. Determine the average width and its standard deviation.
What is the value of x in the triangle below?
Answer:
15 cm
Step-by-step explanation:
All of the triangles in this figure are similar 30°-60°-90° triangles.
The ratio of shortest to longest sides in a 30°-60°-90° triangle is 1 : 2. This means the longest side of the largest triangle has length ...
2 × (10 cm) = 20 cm
It also means the shortest side of the smallest triangle is (10 cm)/2 = 5 cm.
The length shown as 'x' is the difference of these measures:
x = 20 cm -5 cm
x = 15 cm
__
Additional comment
There are several "geometric mean" relations that apply to this sort of right-triangle geometry. One of them is that the side marked as 10 cm is the geometric mean of the short segment and the whole segment of the bottom edge. This will confirm that x = 15 cm.
(10 cm)² = (5 cm)(5 +15) cm = 100 cm²
Solve the equation using inverse operations. Check your solutions. In your final answer, include all of your work. 1/4x3=-27/4
Answer:
x = -3
Step-by-step explanation:
One always uses inverse operations to solve an equation.
1/4x^3 = -27/4
x^3 = -27 . . . . . . . . . multiply by the inverse of 1/4
x = -3 . . . . . . . . . . raise each side to the inverse of the power of 3 (in English: take the cube root)
_____
Check
(1/4)(-3)^3 = 1/4(-27) = -27/4 . . . . as required
