Enrique has a recipe for fruit punch that uses 12 cups of pineapple juice. He wants triple the recipe for a family party. How many quarts of pineapple juice died Enrique need for the party?
A. 9
B.10
C.36
D.4
Answer:
A. 9 quarts
Step-by-step explanation:
Since he wants to triple the recipe you would multiply the 12 cups by 3 to get 36 cups and then you would convert the cups into quarts and 36 cups is equal to 9 quarts

SO MARK THE PERIMETER AND THE FORMULA FOR FINDING TRAPEZUIM IS
area=1/2 (a+b)h
Answer:
144 cm²
Step-by-step explanation:
5x + 12x + 6x + 5x = 56
=> 28x = 56
=> x = 2
DC => 6x = 6(2) = 12
AB => 12x = 12(2) = 24
BC => 5x = 5(2) = 10
AD => 5x = 5(2) = 10
trapezium is an isosceles trapezium because a trapezium with a pair of non-parallel sides(BC&AD) that have equal distances, which are congruent, is an isosceles trapezium.
Thus, the base of the two triangles on each side are congruent.
base: (AB - DC) ÷ 2 = (24 - 12) ÷ 2 = 6
calculate the height using Pythagorean theorem => √10² - 6² = 8
area of the isosceles trapezium ABCD: (12 + 24) × 8 ÷ 2 = 144
The diameter of a sphere is multiplied by 1/5. What is the effect on the surface area?
Answer choices:
5 times bigger
5 times smaller
25 times bigger
25 times smaller
15 times bigger
15 times smaller
125 times bigger
125 times smaller
Answer is not here
Answer:
25 times smallerStep-by-step explanation:
Scale factor is:
k = 1/5Ratio of surface areas is:
k² = (1/5)² = 1/25Surface area will be 25 times smaller
Correct choice is D
We know the ratio of sides to area
a/b=a²/b²So
If diameter is multiplied by 1/5
Surface are increases
(1/5)²1/2525 times smaller
what is the next step in solving this equation
a. -5x-8=9
b. -13x=9

If a point at random, what is the probability that it will be in the shaded section. Give your answer as a fraction or a percentage to the hundredths
The diagram isn't attached. However, a rated diagram has been found and attached below.
Answer:
0.8611
Step-by-step explanation:
The probability of an event involves taking the ratio of the required measurement and the entire measurement.
Based on information on the attached circle, the shaded region of the circle takes 310° of the entire 360°
Choosing a point at random from which nside the circle ;
P(shaded portion) = shaded section / total measure of circle
P(shaded point) = 310 / 360 = 0.8611

if the 55 employees who work overtime make up approximately 42% of all employees at the company, how many employees are there in total
Answer:
Approximately = 131 employees in total
Step-by-step explanation:
if the 55 employees who work overtime make up approximately 42% of all employees at the company, how many employees are there in total?
Let us represent total number of employees = x
Hence,
42% of x = 55 employees
42/100 × x = 55
42x/100 = 55
Cross Multiply
42x = 100 × 54
x = 100 × 55/42
x = 130.95238095 employees
Therefore, there is approximately a total 131 employees

Step-by-step explanation:
Study the function below and then answer the questions that follow. Equation What is the domain of f(x)? What is the range of f(x)?
Answer:
(a) Domain: All real numbers except -2
(b) [tex]f(x) > -4[/tex]
Step-by-step explanation:
Given
See attachment for f(x)
Solving (a): The domain
From the attached image, we have:
[tex]f(x) = -x - 2, x <-2[/tex]
[tex]f(x) = -x^2, -2 < x < 0[/tex]
[tex]f(x) = x, x \ge 0[/tex]
To get the domain, we consider the inequalities attached to each of the piece-wise function
[tex]x < -2[/tex]
This implies that the values of x is less than -2 i.e.
[tex]x = \{.......,-4,-3\}[/tex]
[tex]-2< x<0[/tex]
This implies that x is greater than -2 and less than 0 i.e.
[tex]x = \{-1\}[/tex]
[tex]x \ge 0[/tex]
This implies that x is greater than or equal to 0 i.e.
[tex]x =\{0,1,2,3,....\}[/tex]
If these values of x are merged, we have:
[tex]x = \{.......,-4,-3,-1,0,1,2,3.....\}[/tex]
[tex]x = \{-\infty,..,-4,-3,-1,0,1,2,3,...,\infty\}[/tex]
-2 is not included in the above values of x.
Solving (b): The range
From the attached image, we have:
[tex]f(x) = -x - 2, x <-2[/tex]
[tex]f(x) = -x^2, -2 < x < 0[/tex]
[tex]f(x) = x, x \ge 0[/tex]
Substitute the greatest value of x in each piece-wise function.
[tex]f(x) = -x - 2, x <-2[/tex]
[tex]x=-2[/tex]
So;
[tex]f(-2) = -2-2 = -4[/tex]
[tex]f(x) = -x^2, -2 < x < 0[/tex]
[tex]x = -2[/tex]
So:
[tex]f(-2) = -2^2 = -4[/tex]
[tex]f(x) = x, x \ge 0[/tex]
[tex]x = \infty[/tex]
So;
[tex]f(\infty) = \infty[/tex]
We have:
[tex]f(-2) =-4[/tex]
[tex]f(-2) =-4[/tex]
[tex]f(\infty) = \infty[/tex]
The smallest value of f(x) is -4
Hence, the range is:
[tex]f(x) > -4[/tex]
Answer:
Domain is
B)
(-infinity, -2) U (-2, infinity)
Range is (-4, infinity)

Answer: The answer is 280 ft.
Step-by-step explanation:
divide the green area into a triangle and a rectangle so it's easier to calculate. Then find the area of the rectangle by multiplying 14 times 16. That should get you 224. Then, find the area of the tringle by multiplying 14 times 18, times 1/2. That will get you 56. If you add 56 to 224, that gets you 280.
In a trapezoid, the length of one base is equal to its height and the length of the other base is twice its height. If the height is 10 centimeters, what is the area of the trapezoid?
Explain how you found your answer.
Enter the correct answers in the boxes.
Answer:
150cm²
Step-by-step explanation:
In a trapezoid, the length of one base is equal to its height and the length of the other base is twice its height. If the height is 10 centimeters, what is the area of the trapezoid?
The formula for the area of a trapezoid = 1/2(a + b) h
Where a = Length of the first base
b = Length of the second base
h= height of the trapezoid
h = 10cm
The length of one base is equal to its height
Hence:
a = h = 10cm
The length of the other base is twice its height.
b = 2h
h = 10cm
b = 10 × 2 = 20cm
Therefore, the Area of the Trapezoid =
1/2 (20 + 10)10
1/2 × 30 × 10
= 150cm²
Factorize completely
2x^2+4x-6
Answer:
Solution given;
2x²+4x-6
2x²+6x-2x-6
2x(x+3)-2(x+3)
(x+3)(2x-2)
is your answer
Answer:
2(x + 3)(x - 1)
Step-by-step explanation:
Given
2x² + 4x - 6 ← factor out 2 from each term
= 2(x² + 2x - 3) ← factor the quadratic
Consider the factors of the constant term (- 3) which sum to give the coefficient of the x- term (+ 2)
The factors are + 3 and - 1 , since
3 × - 1 = - 3 and 3 - 1 = + 2 , then
x² + 2x - 3 = (x + 3)(x - 1) , so
2x² + 4x - 6 = 2(x + 3)(x - 1) ← in factored form
solve the inequality m - 3 less than -2
Answer:m>1
Step-by-step explanation:
You add 3 to both sides because you minusing the 3. Then since your working with a negative you have to switch the signs
A. Their rates of change differ by 2. B. Their rates of change differ by 4. C. Function M has a greater rate of change than Function P. D. Function M and Function P have the same rate of change.
Answer:
(a) Their rates of change differ by 2
Step-by-step explanation:
Given
See attachment for functions M and P
Required
Determine what is true about the rates of M and P
First, we calculate the slope (i.e. rate) of both functions.
Slope is calculated as:
[tex]m = \frac{y_2 -y_1}{x_2 - x_1}[/tex]
From the table of M, we have:
[tex](x_1,y_1) = (-2,-9)[/tex]
[tex](x_2,y_2) = (2,11)[/tex]
So, the slope is:
[tex]m_M = \frac{11 --9}{2--2}[/tex]
[tex]m_M = \frac{20}{4}[/tex]
[tex]m_M = 5[/tex]
For function P, we have:
[tex]y = 7x + 9[/tex]
A function is represented as:
[tex]y = mx + b[/tex]
Where:
[tex]m = slope[/tex]
So, by comparison:
[tex]m_P = 7[/tex]
At this point, we have:
[tex]m_M = 5[/tex] --- Slope of M
[tex]m_P = 7[/tex] --- Slope of P
Only option (a) is true because both slopes differ by 2. i.e. 7 - 5 = 2
Other options are not true

the diagram shows a cuboid.what is the surface area of the cuboid
plz help
Answer:
202 cm
Step-by-step explanation:
You need to add the areas of the faces, and since it is a cuboid opposite faces are the same. If you do 2(5x9) + 2(4x9) + 2(4x5) you will get your answer.
Answer:
Hello Love! Answer: 202
Step-by-step explanation:
First off we have to do all 6 faces remember that each face will have a matching face that goes along with it so Imma start with the front face that would be 9 x 5 = 45 same for back face
Then ill do sides that will be 5 x 4 = 20 for both left and right sides Then ill do top and bottom
thats 4 x 9 = 36 Now ill add all of these up.
So 45 + 45 + 20 + 20 + 36 + 36 and that = 202
