rectangle is 24 inches. What are the dimensions of the rectangle?
O
A length = 12 in.; width = 8 in.
B length = 8 in.; width = 4 in
c length = 8 in.; width – 6 in.
D length = 6 in.; width = 2 in.
Answers
Answer:
B length = 8 in.; width = 4 in
Step-by-step explanation:
Given
the length L = w + 4
Perimeter = 24 inches
Perimeter of a rectangle
= 2(L + W)
We now have two equations.
Equation 1: L = w + 4
Equation 2: P = 2(L + W)
Substitute L as w + 4 into equation 1. And 24 for p
Therefore
24 = 2(w + 4 + w)
24 = 2(2w + 4)
Distribute 2 into (2w + 4)
We have
24 = 2 x 2w + 2 x 4
24 = 4w + 8
Subtract 8 from both sides
24 - 8 = 4w + 8 - 8
16 = 4w
Divide both sides by 4
16/4 = 4w/4
4 = w
w = 4 inches
Now substitute 4 for w into either of the equations to get
L.
Using equation 1 , we have
L = w + 4
L = 4 + 4
L = 8 inches

Which equation can you use to find the number of letters n Ellen receives?
Answers
Answer:
Ellen receives a bunch of fan mail. She splits them all into 3 equal stacks to open up with her mom and sister and each stack contains 21 letters.
To find the total number of letters that Ellen has recieved we have to add up all the letters in the 3 piles.
Your equation would be 21*3=n
You would times 21 by 3 because there are 21 letters in each stack.
Where n would represent the number of letter that Ellen has recieved.
To solve for n you would simply go 21*3=63.
Ellen has revieved a total of 63 letters.

How many minutes will it take the school bus to complete the 52-km trip back to the school at an average speed of 1.0 km/min?
Answers
If the school bus travels at an average speed of 1.0 km/min, it will take 52 minutes to complete the 52 km trip back to the school.
It is given in the question that the school bus is traveling at an average speed = 1.0 km/min
The total distance the school bus will cover on the trip back to the school is = 52 km
According to the formula of speed,
Speed = Distance/Time
So, Time = Distance/Speed
Substituting the given values of distance and speed, we get
Time = 52 km/1.0 km/min
= 52 minutes
Therefore, the time being taken by the school bus to complete the 52 km trip back to the school (average speed = 1.0 km/min) = 52 minutes

The 1997 a value of an object was $5000. In 2012, it was worth $9500. The annual percent growth has been constant. What is the annual percent growth?
Answers
Solution:
The increasing function is given as:
[tex]y = a(1+r)^t[/tex]
Where,
y is future value
a is initial value
r is growth rate
t is number of years
From given,
a = 5000
y = 9500
t = 1997 to 2012 = 15 years
r = ?
Substituting the values we get,
[tex]9500 = 5000(1+r)^{15}\\\\(1+r)^{15} = 1.9\\\\Take\ \frac{1}{15}th\ power\ on\ both\ sides\\\\1+r = (1.9)^{\frac{1}{15}}\\\\1+r = 1.04367\\\\r = 1.04367 - 1\\\\r = 0.04367\\\\In\ percentage,\\\\r = 0.04367 \times 100 \%\\\\r = 4.367 \% \approx 4.37 \%[/tex]

An antique store is getting ready for their annual show in mark up all the prices by 25% if their most expensive item they have to markup is originally $840 what will be the show price be
Answers
Answer:
$1050
Step-by-step explanation:
The show price will be 25% of $840 and the result added to $840.
Therefore
25% of $840
25% /100% x $840
0.25 x $840
$210
Show price = $840 + $210
= $1050
The show price will be $1050
Final answer:
The show price of the most expensive item after the 25% markup will be $1050.
Explanation:
To determine the show price, we need to calculate a 25% markup on the original price of $840. This markup represents the additional amount added to the original price to determine the final selling price.
To calculate the markup amount, we multiply $840 by 0.25. This gives us $210, which represents the 25% of the original price.
Next, we add the markup amount to the original price. $840 plus $210 equals $1050. This means that the final show price of the most expensive item, after applying a 25% markup, will be $1050.
Therefore, the show price of the most expensive item after the 25% markup will be $1050.

Which scale did the architect use to create the scale of the sports stadium?
Answers
Answer:
Scale did the architect use to create the scale of the sports stadium is 1 inch = 15 feet.
Step-by-step explanation:
Given : An architect build a scale model of a sports stadium that was 12 inches. The actual height of the building was 180 feet.
To find : Which scale did the architect use to create the scale of the sports stadium?
Solution :
An architect build a scale model of a sports stadium that was 12 inches.
The actual height of the building was 180 feet.
The scale is determined by number of feet used in 1 inch.
i.e. For 12 inches it is 180 feet
For 1 inch = [tex]\frac{180}{12}[/tex] feet
1 inch = 15 feet
Therefore, scale did the architect use to create the scale of the sports stadium is 1 inch = 15 feet.

What is the answer to -3x+2y=5
3x+y=7
Answers
Answer:
x=1
y=4
(1, 4)
Step-by-step explanation:
To solve simultaneous equation, we can use either of these three methods. Substitution method, elimination method or graphical method. But for the purpose of this question, we would be using the elimination method.
-3x+2y=5 Equation 1
3x+y=7. Equation 2
Since in the two equations, x has the same coefficient, we can eliminate x by adding both equations together
-3x+3x=0
2y+y=3y
5+7=12
We now have 3y=12
Divide both sides by 3
y=12/3
y=4
Substitute y for 4 in equation 2.
3x+4=7
3x=7-4
3x=3
Divide both sides by 3
x=3/3
x=1
x=1 and y=4

Answers
Answer:
The lengths of time that his mom reads are typically longer and have more variability than the lengths of time that his dad reads.
Step-by-step explanation:
This is because the range is greater and the minimum and maximum are higher numbers.
The solution to the box plot is is the lengths of time that his mom reads are typically longer and have more variability than the lengths of time that his dad reads.
What is box plot?A box and whisker plot, often known as a box plot, shows a data set's five-number summary. The minimum, first quartile, median, third quartile, and maximum make up the five-number summary.
A box is drawn from the first quartile to the third quartile in a box plot. At the median, a vertical line passes through the box.
It is used when showing the distribution of data points across a selected measure and if the box in a box plot is stretched in one direction or the other, then the data is skewed in that direction.
Given data ,
Let the box plots be represented as A and B
Now , the box plot A represents the minutes Mom used to spend during reading
And , the box plot B represents the minutes Dad used to spend during reading
From the box plots , we can see that the range is greater in the box plot A and the minimum and maximum are higher value numbers when Mom is reading the bedtime stories
Hence , from the box plots lengths of time that his mom reads are typically longer and have more variability than the lengths of time that his dad reads

1/9 + x = 1/2
What fraction is X?
Answers
Final answer:
The equation 1/9 + x = 1/2 is solved by finding a common denominator and subtracting the fractions, which results in x = 7/18.
Explanation:
To solve the equation 1/9 + x = 1/2, we need to find the value of x.
First, we'll align the equation to isolate x:
1/9 + x = 1/2x = 1/2 - 1/9Next, we must have a common denominator to subtract the fractions. The least common denominator (LCD) for 9 and 2 is 18. We convert both fractions to have this common denominator:
x = (9/18) - (2/18)Now we subtract the numerators:
x = 9/18 - 2/18x = (9 - 2)/18x = 7/18Thus, the value of x is 7/18.
