1) Who walks at a faster rate: someone who walks 60 feet in 10 seconds or someone who walks 42 feet in 6 seconds?
Answer:
The rate is the distance divided by the time.
60 feet in 10 seconds = 60 ft / 10 sec = 6 ft / sec
42 feet in 6 seconds = 42 ft / 6 sec = 7 ft / sec <--- We have a winner!

Least common denominator of 6/7 and 5/14
Answer:
14
Step-by-step explanation:
You can‘t simplify 5/14 because 5 is a prime number. So, now you have to convert the 6/7 to 12/14 to match it up to 5/14. They now have a common denominator of 14.
Hope this helps! :)
When Mr. Woodard preheated his oven, the oven's temperature rose 3 degrees in 1/6 of a minute. At that rate, how much will the oven heat up in 1 minute?
Given:
Oven's temperature rose 3 degrees in [tex]\dfrac{1}{6}[/tex] of a minute.
To find:
How much will the oven heat up in 1 minute at that rate?
Solution:
According to the question,
Oven's temperature rose in [tex]\dfrac{1}{6}[/tex] of a minute [tex]=3 \text{ degrees}[/tex]
Oven's temperature rose in 1 minute [tex]=6\times 3 \text{ degrees}[/tex]
[tex]=18 \text{ degrees}[/tex]
Therefore, the oven's will heat up 18 degrees in 1 minute.
Answer:
18
Step-by-step explanation:
therefore it will be 18 degrees in 1 min

First to answer
Answer:
The answer is True:
Let's solve your equation step-by-step.
1/n−1 = 4/15
Step 1: Cross-multiply.
1/n−1 = 41/ 5
(1)*(15)=4*(n−1)
15=4n−4
Step 2: Flip the equation.
4n−4=15
Step 3: Add 4 to both sides.
4n−4+4=15+4
4n=19
Step 4: Divide both sides by 4.
4n/4=19/4
n=19/4
simplify:
19/4 = 4.75
4.75 in decimal for is equal to 4 3/4
James puts $3,500 into a savings account that earns 2.5% simple interest. He does not touch that account for 3 years. What would the new balance of the account be after 3 years?
Given :
James puts $3,500 into a savings account that earns 2.5% simple interest.
He does not touch that account for 3 years.
To Find :
The new balance of the account be after 3 years.
Solution :
Interest on $3500 after 3 years is :
[tex]I = \dfrac{P_o\times r\times t}{100}\\\\I = \dfrac{3500\times 2.5\times 3}{100}\\\\I = \$262.5[/tex]
So, new balance of the account after 3 years is $( 3500+262.5 ) = $3762.5 .
Hence, this is the required solution.

8 customers entered a store over the course of 16 minutes. At what rate were the customers entering the store in minutes per customer? 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 8 customers 16 minutes 8 customers 16 minutes Resize the right columns to represent the unit rate. Resize these You must answer all questions above in order to submit.
Answer:
2min/customerStep-by-step explanation:
If 8 customers entered a store over the course of 16 minutes, then;
8 customers = 16 minutes.
The rate at which the customers are entering is expressed as;
Rate = Time (in minutes)/amount of customers;
Given
Time = 16 minutes
Amount of customers = 8 customers
Rate = 16min/8customers
Rate = 2min/customer
Hence the rate at which the customers entering the store in minutes per customer is 2min/customer.

Solve for y.
-2(y-7) =9y – 30
Simplify your answer as much as possible.
Answer:
y=4
Step-by-step explanation:
-2(y-7)=9y-30
Do distributive property-2y+14=9y-30
Move the terms-2y-9y=-30-14
Collect like terms-11y=-30-14
Calculate the difference-11y=-44
Divide both sides by -11y=4
A line has a slope of 10 and passes through the point (0, 7). What is its equation in slope intercept form?
Answer:
slope is 10x
Y - intercept is 7
Step-by-step explanation:
The equation of the line whose slope is 10 and passes through the point (0, 7) is y = 10x + 7
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
We have a line that has a slope of 10 and passes through the point (0, 7).
Assume the equation of the line to be -
y = 10x + c {since m = 10}
For the point (0, 7), we can write -
7 = 10 x 0 + c
c = 7
So, the equation of the line will be -
y = 10x + 7
Therefore, the equation of the line whose slope is 10 and passes through the point (0, 7) is y = 10x + 7

There is a wall of 13 feet long and you want to hang three equally-sized travel posters of 2 feet width, on a wall so that the posters on the ends are each 1.75 feet from the end of the wall. You want the spacing between posters to be equal. Write and solve an equation to determine how much space you should leave between the posters.
Answer:
Spacing between the posters will be 1.75 each
Step-by-step explanation:
We are given
The length of the wall = 13ft
width of the poster = 2ft ⇒2*3=6ft for three posters
Poster's from end of the wall = 1.75*2 = 3.50ft
let the spacing be = x ⇒ 2x for two spacing between three posters
Total length of the wall = 6 + 3.50 + 2x = 13
2x + 9.50 = 13
2x = 3.50
x = 1.75ft
So the spacing between the posters will be 1.75 each
Johnny and Cage are working together to mold figurines for a craft fair. They already have 8 figurines which were left from the last craft fair. Johnny and Cage can mold 3 figurines every hour. Explain the reasons why this situation is linear.
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]Initial = 8[/tex]
[tex]Increment = 3[/tex] (every hour)
Required
Explain why it is linear
First, we need to determine the equation that represents the scenario
Let x be the number of hours worked and y be the number of figurines at x hours.
The equation is determined as follows:
[tex]y = Initial\ Figurines + Increment * x[/tex]
This gives:
[tex]y = 8 + 3 * x[/tex]
[tex]y = 8 + 3x[/tex]
Reorder
[tex]y = 3x + 8[/tex]
A linear equation is of the form
[tex]y = mx + b[/tex]
By comparison,
[tex]y = mx + b[/tex] is equivalent to [tex]y = 3x + 8[/tex]
Hence, we can conclude that the situation is linear
Answer:
The situation can be described using the equation y = 3x + 8

If y = 12 when x = 6, determine y when x = 18.
if m=-2,then what is n in this equation
Answer:
n=-1
Step-by-step explanation:
Plug in m=-2 into the given equation and solve
5(-2 - n) =5n
Distribute the 5 to the -2 and -n
-10-5n=5n
Isolate the variable to one side by adding 5n to the right side of the equation.
-10=10n
Isolate the variable by dividing by 10 on both sides.
-1 = n

What is 5/9+7/12? as a fraction in simplest form?
Answer:
1 5/36
Step-by-step explanation:
To add fractions, you need to have a common denominator between the two fractions.
In this case, the lowest common denominator would be 36. Convert each fraction.
5/9 = 20/36 (multiply the numerator and denominator by 4)
7/12 = 21/36 (multiply top and bottom by 3)
20/36 + 21/36 = 41/36
Then you need to simplify the fraction. 36 goes into 41 once (1), with a remainder of 5, so you would get 1 5/36.

An account grows at an annual interest rate of r, so it grow by a factor of x=1+r each year. The function gives the amount in the account after 4 years when the growth factor is x. What is the total amount in the account if the interest rate for the account is 3% each year?
Complete question :
An account grows at an annual interest rate of r , so it grows by a factor of x = 1+ r each year. The function A(x)= 800x^4 + 350x^3 + 500x^2 + 600x gives the amount in the account after 4 years when the growth factor is x.
1) What is the total amount in the account if the interest rate for the account is 3% each year?
Answer:
2,431.311498
Step-by-step explanation:
Given that:
Growth factor (x) = (1 + r) per year
If rate (r) = 3% = 0.03
x = 1 + 0.03 = 1.03
Amount in account after 4 years is given by the function :
A(x)= 800x^4 + 350x^3 + 500x^2 + 600x
Put x = 1.03 to obtain the total amount ;
A(1.03) = 800(1.03)^4 + 350(1.03)^3 + 500(1.03)^2 + 600(1.03)
= 2431.311498
Hence, total amount in account after 4 years = 2,431.311498
What is the standard form of –23f² + f/2 = –√3?
Answer:
y = -23f^2 + 1/2f + √3
Step-by-step explanation:
Standard form: y = ax^2 + bx + c
x = f
a = -23
b = 1/2
c = √3
–23f² + f/2 = -√3
-23f² + f/2 + √3 = 0
y = -23f^2 + f/2 + √3
y = -23f^2 + 1/2f + √3
