Answer:
140 + 96 m
Step-by-step explanation:
There are 4 weeks in 1 month.
Therefore:
Jonny has $50 in a savings account. Each week, he deposits $13 in the account.
$50 + $13 × 4m
The algebraic expression is given as:
50 + 52m
Jonny's brother has $90 in a saving account.
Each week, he deposits $11 in the account.
The algebraic expression is given as:
$90 + $11 × 4m
90 + 44m
An algebraic expression to describe how much money Jonny and his brother will have in their accounts after m months is written as:
Amount Jonny has + Amount his brother has
50 + 52m + 90 + 44m
= 50 + 90 + 52m + 44m
= 140 + 96 m
Michael's lawn mower had 3/8 of a gallon of gasoline in the tank. He started mowing and used all of the gasoline. He put 4/10 of a gallon of gasoline in the tank. After he mowed, 2/4 of a gallon was left in the tank. What was the total amount of gasoline Michael used?
Answer:
11/40 of a gallon
Step-by-step explanation:
The amount of gasoline in the tank of lawn mower = 3/8 of a gallon
Then he put the amount of gasoline in the tank = 4/10 of a gallon
The total amount of gasoline filled in the tank = 3/8 + 4/10
= 3/8 + 2/5
= 15+16/40
= 31/40
The total amount of gasoline filled in the tank = 31/40
The amount of gasoline left in the tank after mowing = 2/4
Total amount of gasoline Michael used = 31/40 - 2/4
= 31-20/40
= 11/40 of a gallon
Alternatively, you can follow this method:
Total amount of gasoline Michael used = 3/8 + (4/10 - 2/4)
= 3/8 + (2/5 - 2/4)
= 3/8 + ( 8-10/20)
= 3/8 + (-2/20)
= 3/8 + (-1/10)
= 3/8 - 1/10
= 30-8/80
= 22/80
= 11/40 of a gallon
Total amount of gasoline Michael used = 11/40 of a gallon
Which function defines (g•f)(x)?
Answer:the Awnser would be d
Step-by-step explanation:
Plato
This relationship represents between f(x) and g(x) :
(g•f)(x) = 5xlog(5x) + 4log(5x) which is correct option(D).
What is function?The function is defined as mathematics expression defines a relationship between one variable and another variable.
f(x) = log(5x)
g(x) = 5x + 4
Multiply by f(x) in g(x),
(g•f)(x) = (5x + 4)f(x)
(g•f)(x) = 5xf(x) + 4f(x)
Substitute value of f(x),
(g•f)(x) = 5xlog(5x) + 4log(5x)

Emile is a long distance trucker. In one week he drives 750 miles from his home in fort lauderale,FL, to Benson, NC he then drives 2,488 miles to Barstow, CA and continues driving 155 miles to Bakersfield,CA. From there, Emily drives 1,015 miles to Seattle, WA.
Estimate the total distance Emile travels by first rounding each distance to the nearest hundred.
Answer:
4500 miles
Step-by-step explanation:
750 rounded to the nearest hundred is 800. 2,488 rounded to the nearest hundred is 2,500. 155 rounded to the nearest hundred is 200. 1,015 rounded to the nearest hundred is 1,000. So 800+2,500+200+1,000= 4,500
If the graph of the function moves to the right two units what is the new vertex of the function
Answer:
Let's talk through this a one step at a time.
*Since f(x) is concave-up with its vertex on the x-axis, we know f(x) ≥ 0.
*We also know that when we shift a function's domain by a positive number, we shift the function left and when we shift a function's domain by a negative number, we shift the function right. So f(x-5) is f(x) shifted to the right by 5.
*At this point, f(x-5) has its vertex at (5,0).
*When we negate f(x-5), the parabola becomes concave down yet the vertex remains at (5,0). Now we're at -f(x-5). At this point we have -f(x-5)≤0 with a range (-∞,0]
*If we add 2 to create g(x)=2-f(x-5), then we have a concave down parabola with its vertex shifted up by 2, at (5,2). So, g(x) is concave down with its vertex at (5,2). Hence

Factor the trinomial. Show ALL work: x2 − 5x + 6
Answer:
(x−2)(x−3)
Step-by-step explanation:
x²−5x+6
number = x-y = -5
x*y=6
-2+-3 = -5
-2*-3 = 6
we get
(x-2)(x-3)
Answer:
(x−2)(x−3)
Answer: x=3,x=2: (x-3)(x-2)
Step-by-step explanation: Lets factor. What two numbers multiply to get 6 and add to get 5.
The two numbers are 3 and 2 so lets start factoring.
First since its not a perfect square trinomial we know it wont be something squares.
We put (x ?)(x ?) the question marks are numbers that will go in so the two numbers are 3 and 2 and since the sign in front of the 5x is a minus sign both numbers will be negative. So we would do (x 3)(x 2) and both signs would be negative so we get (x-3)(x-2)

Timothy spent 1 hour 22 minutes less than Bill reading last week. Bill spent 47 minutes less than Pete. Pete spent 3 hours reading. How long did Timothy spend reading?
Answer: 51 minutes
Step-by-step explanation:
Firstly, Pete spent 3 hours reading. Bill spent 47 minutes less than Pete reading so Bill spent:
= 3 hours - 47 minutes
= 2 hours 13 minutes
If Bill spent 2 hours 13 minutes reading and Timothy spent 1 hour 22 minutes less than this, the amount of time that Timothy read for was:
= 2 hours 13 minutes - 1 hour 22 minutes
= 51 minutes

Karina wants to fill the base so that it is 85% full. What is the volume of the base that she is filling? (Find 85% of the volume).
Question:
Karina has recently begun kickboxing and purchased training equipment as modeled in the diagram below. The cylindrical base is 15 inches tall with a diameter of 22 inches.
Karina wants to fill the base so that it is 85% full. What is the volume of the base that she is filling? (Find 85% of the volume).
Answer:
[tex]Section = 4847.3205\ in^3[/tex]
Step-by-step explanation:
Given
[tex]h = 15in[/tex] -- height
[tex]d = 22in[/tex] -- diameter
Required
85% of the volume
First, calculate the radius
[tex]r = \frac{1}{2} * d[/tex]
[tex]r = \frac{1}{2} * 22= 11in[/tex]
The volume (V) is then calculated using:
[tex]V = \pi r^2h[/tex]
[tex]V = 3.142* 11^2 * 15[/tex]
[tex]V = 5702.73\ in^3[/tex]
85% of the volume is:
[tex]Section = 85\% * V[/tex]
[tex]Section = 85\% * 5702.73\ in^3[/tex]
[tex]Section = 4847.3205\ in^3[/tex]

ellie wanted to order candy online. company A us offering 2 1/2 pounds of chocolate for $32.50; while company B is offering 2 3/4 pounds of the same chocolate for $35.00. what is the unit price for company A? (please include units) what is the unit price for company B? which company is offering the lowest price per pound?
Answer:
Company A = $13
Company B = $12.73
Company B
Step-by-step explanation:
To determine the unit cost for each company, divide the price of chocolate by the number of pounds
Unit cost = price ÷ total pounds offered
Company A
$32.50 ÷ 2 1/2
$32.50 ÷ 5/2
$32.50 x 2/5 = $13
Company B
$35 ÷ 2 3/4
$35 ÷ 11/4
$35 X 4/11 = $12.73
$12.73 is less than $13. Company b has a lower price per pound
20 feet. The builder asks him to give the measurements in yards. What will be the length in yards?Immersive Reader
Answer:
6.67 yards
Step-by-step explanation:
20 feet. The builder asks him to give the measurements in yards. What will be the length in yards?
Please note that:
1 foot = 0.333 yard
20 feet = x yards
Cross Multiply
1 foot × x yards = 20 feet × 0.333 yards
x yards = 20 feet × 0.333 yards/1 foot
x yards = 6.66667 yards
Approximately = 6.67 yards
Therefore, the measurements in yards is 6.67 yards.

Veronica is an English tutor. She charges $60 for each tutoring session plus $0.75 per mile that she has to drive to and from the session. Write an equation to represent this situation. Explain how you got your equation.
Answer:[tex]60+0.75x[/tex]
Step-by-step explanation:
Given
Veronica charges $60 for each tutoring session
Also, there is an additional charge of $0.75 per mile
Suppose she drive x miles and the total cost is represented by C
the additional cost of driving is [tex]0.75\times x=0.75x[/tex]
[tex]\therefore[/tex] The total cost for the session will be the sum of fixed cost and variable driving cost
[tex]\Rightarrow C=60+0.75x[/tex]
A car bought for $13,000 depreciates at 15% per year. Use an exponential function to find the value of the car after 5 years.
Answer:
$5768.1
Step-by-step explanation:
Given data
Cost price= $13,000
Depreciation= 15%
Time= 5 years
The expression for the depreciation is given below
A= P(1-r)^t
Substitute
A=13000(1-0.15)^5
A=13000(0.85)^5
A=13000*0.4437
A=$5768.1
Hence after 5 years, the car will be $5768.1
