Your mother gave you $13.32 with which to buy a present. This covered 3/5 of the cost. How much did the present cost
Answer:
$22.20
Step-by-step explanation:
We are told that $13.32 only covered 3/5 of the cost. Does this mean it covered the whole cost? No. The 5 in the denominator represents the whole cost, and the 3 represents the fraction of the cost. In this case, 13.32 represents the 3, as it did not cover the whole cost.
Let's set up our equation by making 13.32 into a fraction.
13.32/x
We will represent the present's actual cost with the letter x.
13.32/x = 3/5
We want to make sure the 13.32 is in the numerator, equal to the 3 in the numerator in the 3/5 number, because we know that $13.32 only covered for a fraction of the present's cost, not the whole cost.
We solve this by doing cross multiplication. Multiply the 13.32 by the 5.
13.32 x 5 = 66.6
Next we divide 66.6 by 3 to get 22.2
66.6/3 = 22.2
This gives us our final answer of $22.20. This means that the cost of the original present was $22.20
The question involves setting up a proportion to find the total cost of the present. This was done step-by-step by dividing $13.32 by 3 to find 1/5 of the cost, and then multiplying by 5 to find the full cost. The present cost approximately $22.20
Explanation:The subject of your question is mathematics, particularly a topic in proportion. The information given is that $13.32 represents 3/5 of the cost of the present. We could set up a proportion to help calculate the full cost. If 3/5 is equal to $13.32, then 1 (or 5/5) would be equal to the full price of the present. We can solve for the full price by dividing $13.32 by 3 and then multiplying by 5 (since 5/5 represents the whole or full cost).
Step-by-step:
Divide $13.32 by 3. This gives you approximately $4.44, which represents the cost for 1/5 of the present. Multiply $4.44 by 5. This will give you the full cost of the present which is approximately $22.20.Learn more about Proportion here:https://brainly.com/question/31548894

What is the slope of a line perpendicular to the line whose equation is y=2x + 5?
slope=-1
slope =-1/2
slope=-2
Answer:
-1/2
Step-by-step explanation:
For a line to be parallel, they must be equal, for it to be prependicular, the slope must have an opposite value and be over the value.
Answer:
[tex]\frac{-1}{2}[/tex]
Step-by-step explanation:
General form of equation of line = [tex]y= mx+c[/tex]
Where m is the slope of line
We are given a line [tex]y=2x + 5[/tex]
On comparing with general form
m = 2
Let n be the slope of line perpendicular to the line [tex]y=2x + 5[/tex]
The product of the slopes of perpendicular lines is -1
So,[tex]m \times n = -1[/tex]
[tex]2 \times n = -1[/tex]
[tex]n = \frac{-1}{2}[/tex]
So, Option B is correct
Hence the slope of a line perpendicular to the line whose equation is y=2x + 5 is [tex]\frac{-1}{2}[/tex]

Madden and Jenn both worked at the coffee shop today. Madden's total cups of coffee made is represented by f(x); and Jenn's total cups of coffee made is represented by g(x). Use the functions below to write a function that represents the total cups of coffee they made today.
f(x) = 7x − 4
g(x) = 5x + 1
A. 9x + 5
B.9x − 3
C.12x + 5
D.12x − 3
Answer:
The answer is D. 12x - 3.
Step-by-step explanation:
To add these functions, we just add the terms.
f(x) + g(x) = (7x - 4) + (5x + 1)
7x - 4 + 5x + 1 | Simplify
7x + 5x - 3
12x - 3.
Answer:
Option D. (12x - 3)
Step-by-step explanation:
Madden's total cups of coffee made is represented by the function f(x).
f(x) = 7x - 4
Jenn's total cups of coffee made is represented by the function g(x).
g(x) = 5x + 1
Now we have to write a function that represents the total cup of coffee that represents they made.
That will be represented by f(x) + g(x) = (7x - 4) + (5x + 1)
f(x) + g(x) = 12x - 3
Therefore, option D. will be the answer.

what is the distributive property of 5x23
Answer:
see explanation
Step-by-step explanation:
We can express 5 × 23 as
5(20 + 3) ← distribute terms in parenthesis by 5
= 5 × 20 + 5 × 3
= 100 + 15
= 115
By distributive property , the number 5 x 23 = 115
What is Distributive Property?
The distributive property states that multiplying the sum of two or more addends by a number produces the same result as multiplying each addend individually by the number and adding the products together.
For a product of two numbers , a and d , d = b + c
By distributive property ,
a x ( b + c ) = a x b + a x c
Given data ,
Let the number be 5 x 23
Now , the number 23 can be split into ( 20 + 3 )
By opening the parentheses ,
5 x ( 20 + 3 )
The number 5 is first multiplied by 20 and then multiplied by 3 , and the sum of both the products will be taken
So ,
5 x 23 = 5 ( 20 + 3 )
5 x 23 = 5 ( 20 ) + 5 ( 3 )
5 x 23 = 100 + 15
5 x 23 = 115
Hence , by distributive property the product 5 x 23 is 115

If s(x) = 2 - x and f(x) = 3x, which value is equivalent to (s f) (-7)
The equivalent value for (s \\circ f) (-7), given s(x) = 2 - x and f(x) = 3x, is 23.
The question asks which value is equivalent to (s \\circ f) (-7), where s(x) = 2 - x and f(x) = 3x.
To solve for (s \\circ f) (-7), we first need to find f(-7). Since f(x) = 3x, we substitute x with -7:
f(-7) = 3(-7) = -21.
Next, we calculate s(f(-7)), which means we substitute x in s(x) with the value of f(-7):
s(-21) = 2 - (-21) = 2 + 21 = 23.
Therefore, the equivalent value is 23.
Which of the following statements uses the commutative property of addition?
2 + (3 + 4) = (2 + 3) + 4
2 + (3 + 4) = (2+ 3) + (2 + 4)
2 + (3 + 4) = 2 + (4 + 3)
The statement 2 + (3 + 4) = 2 + (4 + 3) is the one that uses the commutative property of addition, which states that changing the order of numbers being added does not affect the sum. So correct answer is first option.
The statement that uses the commutative property of addition is 2 + (3 + 4) = 2 + (4 + 3). The commutative property of addition states that the order in which two numbers are added does not change the sum.
This is represented by the equation A+B=B+A. In our specific example, changing the order of 3 and 4 does not affect the sum when added to 2.
This demonstrates the commutative property in a clear manner.

Andy and Sylvie each incorrectly simplified the expression -3 - 4(2x - 3). Andy wrote -14x + 21 and Sylvie wrote -8 - 6. Explain their errors and give the correct answer.
Answer:
Given the expression -3 - 4(2x- 3) the correct solution is -8x + 9.
Step-by-step explanation:
Andy wrote -14x + 21, so his error was to do de substraction (-3 -4) and then distribute -7(2x-3) = -14x+ 21.
Sylvie wrote -8x -6. Her error was to multiplied -4 only for 2x,
then -3 - 4(2x -3) = -3 -8x -3 = -8x -6.
Andy incorrectly distributed the negative sign and Sylvie made an error in simplifying the expression. The correct answer is -8x + 9.
Explanation:Andy's error: He incorrectly distributed the negative sign to both terms inside the parentheses. When distributing a negative sign to each term, the sign of each term should change. So, -4(2x - 3) becomes -8x + 12. However, Andy erroneously distributed the negative sign to only the first term, resulting in -14x + 21.
Sylvie's error: She incorrectly simplified the expression -8 - 6, which is equal to -14. However, this is not the correct result for the entire expression -3 - 4(2x - 3).
The correct answer is obtained by applying the distributive property and combining like terms. First, simplify the expression inside the parentheses: -4(2x - 3) = -8x + 12. Then, combine the terms outside the parentheses with the simplified expression: -3 - 8x + 12 = -8x + 9.

Determine the area of each face of a cube 306.6
Answer: 51.1 units squared
Step-by-step explanation: the area of each face is 306.6 so then you would divided that by 6 since there are 6 sides in a cube so you get 51.1 and if multiplied by 6 it equals 306.6
The area of each face of a cube 306.6 is 51.1 square units.
What is a cube?A solid three-dimensional shape called a cube contains six square faces, eight vertices, and twelve edges.
A cube has 6 faces.
So the area of each face is (side x side).
So total area is equal to 6 times the area of each side.
Area = 6 x (side x side)
Now, substitute in your numbers and solve for the side length
306.6 = 6 (side)²
so first divide both sides by 6,
we get,
(side)² = 51.1

Tonka weighs 150 lb. He is loading a freight elevator with identical 67-pound boxes. The elevator can carry no more than 2000 lb. If Tonka rides up with the boxes, how many boxes can be loaded on the elevator?
Final answer:
Tonka can load a maximum of 29 boxes on the elevator.
Explanation:
To calculate the number of boxes Tonka can load on the elevator, we need to divide the maximum weight capacity of the elevator by the weight of each box. The weight capacity of the elevator is 2000 lb, and each box weighs 67 lb. Therefore, the number of boxes Tonka can load is found by dividing 2000 lb by 67 lb:
Number of boxes = 2000 lb ÷ 67 lb = 29.85
Since we can't have a fraction of a box, Tonka can load a maximum of 29 boxes on the elevator.

Write an algebraic expression for the phrase.
the sum of b and 11
a. b – 11
b. b/11
c. b + 11
d. 11b
Final answer:
The algebraic expression for the phrase 'the sum of b and 11' is 'b + 11'. This expression represents adding 'b' to '11', and addition is commutative, which means it could also be written as '11 + b'. So the correct option is c.
Explanation:
The phrase 'the sum of b and 11' represents an algebraic expression where sum refers to the addition of two terms. When we talk about the sum of two algebraic expressions, we use the plus sign (+) to denote the operation. Therefore, for the given phrase 'the sum of b and 11a', the algebraic expression is b + 11.
It’s important to keep in mind that in algebra when we want to indicate that one term is multiplied by another, we often place them next to each other without any symbol, which is known as concatenation. And because addition is commutative, we could also write this expression as 11 + b, and it would mean the same thing.
Also worth mentioning is the distinction between the expression 'b - 11' (which means 'b' subtracted by '11') and 'b/11' (which means 'b' divided by '11'). These are different operations and would not correctly represent the phrase we were given to translate into an algebraic expression.
Azeneth is putting a fence around her rectangular garden. The width of the garden is 4x + 5 ft. and the
length is 2x^2 – 3x + 7 ft.
How much total fencing does Azeneth need to buy in terms of x?
Answer:
Azeneth needs to buy 4x² + 2x + 24 feet
Step-by-step explanation:
* Lets explain how to solve the problem
- Azeneth is putting a fence around her rectangular garden
- The width of the garden is 4x + 5 feet
- The length is 2x² – 3x + 7 feet
- We need to find how much total fencing Azeneth needs to buy in
terms of x
∵ The fence will put around the four sides of the rectangular garden
∴ The length of the fence is equal to the perimeter of the garden
- The perimeter of any rectangle = 2l + 2w, where l and w are its
dimensions
∵ The perimeter of the garden = 2 × its width + 2 × its length
∵ Width = 4x + 5
∴ 2 × width = 2(4x + 5) = 8x + 10
∵ Length = 2x² - 3x + 7
∴ 2 × length = 2(2x² - 3x + 7) = 4x² - 6x + 14
∴ The perimeter of the garden = 8x + 10 + 4x² - 6x + 14
- Add like terms
∴ The perimeter of the garden = 4x² + (8x - 6x) + (10 + 14)
∴ The perimeter of the garden = 4x² + 2x + 24
∵ The length of the fence = the perimeter of the garden
∴ The length of the fence = 4x² + 2x + 24 feet
* Azeneth needs to buy 4x² + 2x + 24 feet

Write the equation of the quadratic function with roots -10 and -8 and a vertex at (-9, -3)
Answer:
y = 3x² + 54x + 240
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
here (h, k) = (- 9, - 3), thus
y = a(x + 9)² - 3
To find a substitute either of the roots into the equation
Using (- 8, 0), then
0 = a(- 8 + 9)² - 3
0 = a - 3 ( add 3 to both sides )
a = 3
y = 3(x + 9)² - 3 ← in vertex form
Expand factor and simplify
y = 3(x² + 18x + 81) - 3
= 3x² + 54x + 243 - 3
= 3x² + 54x + 240 ← in standard form
