Answer:
$46.08
Step-by-step explanation:
Hi,
She gets 48 (1.35) when she sells 48 muffins. That equals 64.8.
But she pays 48 (.39) to make them. That equals 18.72.
64.8 - 18.72 = 46.08
She makes $46.08

Answer:
k = 45 . . . miles per hourk = 1/45 . . . hours per mileStep-by-step explanation:
One way we can relate distance and time is ...
time = k × distance
Then the value of k (the constant of proportionality) is ...
k = time/distance = 4 hours/(180 miles)
k = (1/45) hours/mile
__
Another way we can relate the variables is ...
distance = k × time
Then the value of k (the constant of proportionality) is ...
k = distance/time = (180 miles)/(4 hours)
k = 45 miles/hour

In 1985 an antique automobile club had 23,000 members. Since then its membership has grown at an average rate of 5% per year. Assuming this trend continues, how many members will there be in 2020? Round to the nearest thousand.
a) 112,000 members
b) 78,000 members
c) 151,000 members
d) 127,000 members
Answer:
I have come to the conclusion that it is A. 112,000
Answer:
d) 127,000 members
Step-by-step explanation:
In this problem we have an exponential function of the form
where a is the initial value
b is the base
The base is equal to b=1+r
r is the average rate
In this problem we have a=23,000 members
r=5%=5/100=0.05
b=1+0.05=1.05
substitute
x ----> is the number of years since 1985
How many members will there be in 2020?
x=2020-1985=35 years
substitute in the function
Round to the nearest thousand
The graph of f (x) = (x - 2)² + 1 is shown below. What would the new equation of the function be if it is shifted up 2 units?
Answer:
f (x) = (x - 2)² + 3
Step-by-step explanation:
Adding 2 to the constant k would shift the entire equation upwards by 2.
6 friends are going to a bowling alley. They have to pay a fee per game and $2 to
rent shoes. If they plan on only playing one game, the cost is $48.
Answer:
3
Step-by-step explanation:
Let x be the number of games they bowled.
Then, we know that each shoe rental was $2.50. So, the total cost for shoes was 3 * $2.50 = $7.50
The total number of games they bowled was 3 * x (since there were 3 persons).
Now, the cost per game was $5.30. So, the total cost for games bowled (minus shoes) was:
3x($5.30) = $15.90x
Now, add the cost of the shoes ($7.50) and you have the total cost ($55.20):
$15.90x + $7.50 = $55.20
Subtract $7.50 from both sides:
$15.90x = $47.70
Divide both sides by $15.90:
x = 3 (the number of games they bowled)
Which algebraic expression represents the phrase "the quotient of negative eight and the sum of a number and three"
-8
Og+3
8
9+3
-8+g
3
+3
Answer:
[tex]\dfrac{-8}{x+3}[/tex]
Step-by-step explanation:
We need to find an algebraic expression for the given statement i.e. "the quotient of negative eight and the sum of a number and three".
Let the number be x. Quotient means to divide. It means we need to divide -8 and the sum of x and 3.
So, we can write it as follows :
[tex]\dfrac{-8}{x+3}[/tex]
Hence, this is the required solution.
What is the y-intercept for this function?
y = x2 - 2x - 3
Answer:
-3
Step-by-step explanation:
Need the answer for x and y
Answer:
See below
Step-by-step explanation:
There is no 'y' in your question but I will answer the Q in the pic:
the two sides are equal so
10x-1 = 8x+11
2x = 12
x = 6 then CD = 8x+11 = 8(6)+ 11 = 59 units
Jonas has 16 carnations and 12 roses. He wants to make identical bouquets for a party. How many bouquets can he make?
Answer:
Jonas can make 4 bouquets, each containing 4 carnations and 3 roses.
Step-by-step explanation:
Given that Jonas has 16 carnations and 12 roses, and he wants to make identical bouquets for a party, to determine how many bouquets can he make the following calculation must be performed, obtaining the largest common divisor between both numbers:
12 = Divisible by 2, 3, 4, 6 and 12
16 = Divisible by 2, 4, 8 and 16
Thus, the common greatest divisor between the two numbers is 4.
12/4 = 3
16/4 = 4
So, Jonas can make 4 bouquets, each containing 4 carnations and 3 roses.

Answer:
x = 7°
y = 10°
Step-by-step explanation:
7x = 49
x = 7°
180 = 13y + 1 + 49
combine like terms:
13y = 130
y = 10°
Answer:
X equals to 7 & y equals to 10 'cause ;
7X=49
X=7
50 + 13 y + 1 = 180
13y = 130
y=10

If you apply the changes below to the quadratic parent function, f(x) = x?,
what is the equation of the new function?
• Shift 1 unit right.
• Vertically stretch by a factor of 5.
• Reflect over the x-axis.
O A. g(x) = (-5x + 1)2
O B. g(x) = -5(x + 1)2
O C. g(x) = 5x2 - 1
O D. g(x) = -5(x - 1)2
Answer:
The answer is A
Step-by-step explanation:
(D) g(x) = -5(x-1)² is the correct answer for the given changes in function.
What is the function?A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.
The starting parent function is f(x) = x².
To shift 1 unit right, we need to replace x with (x-1).
To vertically stretch by a factor of 5, we need to multiply the function by 5.
To reflect over the x-axis, we need to multiply the function by -1.
So the new function g(x) can be written as:
g(x) = -5(x-1)²
Therefore, the correct answer is (D) g(x) = -5(x-1)².

The area of a rectangular living room is 264 square feet. The length of the room is 2 feet less than twice the width.
What is the width of the living room in feet?
9514 1404 393
Answer:
12 ft
Step-by-step explanation:
Let the width of the room be represented by w. Then the length is (2w-2), and the area is ...
A = LW
264 = (2w-2)w
132 = w² -w . . . . . . . divide by 2, eliminate parentheses
132.25 = w² -w +.25 . . . . . add (-1/2)² to complete the square
√132.25 = w -0.5 . . . . . take the square root
0.5 +11.5 = w = 12 . . . . . add 0.5; use the positive root
The width of the living room is 12 feet.
