Marta's fruit stand sold x oranges on Thursday and twice as many on Friday. All together, on both days, she sold 108.
Which bar diagram represents the equation?
Answer:
Option A
Step-by-step explanation:
It is given that Marta sold [tex]$ x $[/tex] oranges on Thursday.
She has sold twice as many as on Friday. Therefore, she must have sold [tex]$ 2x$[/tex] oranges on Friday.
And the total amounts to 108.
That is, [tex]$ x + 2x = 108 $[/tex]
Hence, the table which has the total on the top and the entities on the bottom line would be the answer which is Option A.
Answer:
A
Step-by-step explanation:
Thursday is x because she sold x oranges. Friday is 2x because she sold double the amount she sold on Thursday. Then we add them together to make 108.
The value of y varies directly as the square of x and y=36 when x=3. What is y when x=4?
Answer: y = 64
Step-by-step explanation:
y <> x² ----------------------- 1
y = kx² ----------------------- 2
36 = 3²k
36 = 9k
K = 36/9
= 4.
To find y when x = 4, we substitute for x in equation 2
y = kx²
y = 4²k
y = 16 x 4
y = 64
The value of y, which varies directly as the square of x, is determined by first identifying the constant of variation from the given values, in this case, y = 36 when x = 3. The constant is found to be 4. Using this constant (k), when x is 4, y will be 64.
Explanation:The value of y varies directly as the square of x, which is represented mathematically as y = kx², where k is the constant of variation. Using the given that y = 36 when x = 3, we can determine k by substituting these values into the equation. Thus, k = y/x² = 36/9 = 4. Now, having the value for k, we can find y when x = 4 by substituting these values into the equation: y = kx² = 4×16 = 64. Therefore, y equals 64 when x equals 4 in the given relation.

Leah wrote 2 different fractions with the same denominator.Both fractions were less than 1. Can their sum equal 1? Can their sum be greater than 1? Explain.
Answer:
1. Yes
2. Yes
Step-by-step explanation:
Leah wrote 2 different fractions with the same denominator. Both fractions were less than 1.
1. Can their sum equal 1?
Let Leah fractions be [tex]\dfrac{6}{7}[/tex] and [tex]\dfrac{1}{7}.[/tex] Both these fractions have the same denominators and are less than 1. Find their sum:
[tex]\dfrac{6}{7}+\dfrac{1}{7}=\dfrac{7}{7}=1[/tex]
2. Can their sum be greater than 1?
Let Leah fractions be [tex]\dfrac{6}{7}[/tex] and [tex]\dfrac{5}{7}[/tex]. Both these fractions have the same denominators and are less than 1. Find their sum:
[tex]\dfrac{6}{7}+\dfrac{5}{7}=\dfrac{11}{7}=1\dfrac{4}{7}>1[/tex]
Two fractions with the same denominator can sum to 1 if their numerators add up to the denominator, or they can sum to more than 1 if their numerators together exceed the denominator. This is based on the concept of adding fractions where only the numerators are summed.
Leah wrote two different fractions with the same denominator, and both were less than 1. Can their sum equal 1? Can their sum be greater than 1? The answer to both questions depends on the value of the numerators. Fractions represent parts of a whole. For two fractions with the same denominator to have a sum of 1, the numerators must add up to the denominator. If their sum is greater than the denominator, then the total sum would be greater than 1.
For example, if we have fractions ½ and ¾, their sum is ½ + ¾ = ¾ which is less than 1. However, if we have ¾ and ¾, the sum equals 6/4, which reduces to 1½, a sum greater than 1.
In conclusion, two fractions with the same denominator and each less than 1 can sum to 1 if the numerators total the denominator, or can sum to greater than 1 if the numerators together exceed the denominator. An important aspect of adding fractions is that we only add the numerators and never the denominators.

Which of the following expressions are equivalent to -8 -(-1)-5
Answer:
Step-by-step explanation:
-8 -(-1)-5
Opening bracket
= -8 + 1 - 5
= -12
The student's expression -8 -(-1)-5 simplifies to -8 + 1 - 5, which is equal to -12 after performing the addition and subtraction sequentially.
The expression in question is -8 -(-1)-5. To solve this, we need to recognize that subtracting a negative number is the same as adding its positive equivalent. So, the expression simplifies to -8 + 1 - 5.
Now, we perform the addition and subtraction in the order they appear:
First, we add 1 to -8, which gives us -7.Then, we subtract 5 from -7, which gives us -12.Therefore, the expression -8 -(-1)-5 is equivalent to -12.
Kelly has a rock garden with a length of 6 feet. She constructs a scale model of the rock garden using
the scale 1 inch:2 feet.
What is the length of the garden in her model? Show your work, including your proportion.
If the width is 5 inches for the scale model and the scale is still 1 inch to 2 feet, will her scale
model drawing fit on a piece of paper that is 8.5 inches by 7 inches? Why or why not?
Answer:
Answer:
3 inches
It will fit in the paper.
Step-by-step explanation:
In the scale drawing the 2 feet original length is converted to 1 inch drawing length as Kelly constructs a scale model of the rock garden using the scale 1 inch : 2 feet.
Now the proportion is 1 inch : (2 × 12) inches = 1 : 24 {Since 1 foot is equivalent to 12 inches}
Now, maintaining that scale ratio the 6 feet original length of the garden will be converted to [tex]\frac{1}{24} \times (6 \times 12) = 3[/tex] inches in the drawing.
It is also given that the width of the garden in the scale model is 5 inches and the scale is still 1 inch : 2 feet.
Therefore, the dimensions of the garden in the model is 3 inches by 5 inches and this will fit on a piece of paper that is 8.5 inches by 7 inches. (Answer)

4.) Mr. Souders purchased a car priced at $9800. He paid $500 down and
agreed to a monthly payment of $250 per month for 48 months.
Including the down payment, what is the total cost of the car?
Please show your work.
Answer:
The total cost of the car including the down payment = $12,500
Step-by-step explanation:
The Original price of the car = $9800
The amount paid for down payment = $500
Also, the monthly payment amount = $250
Now, the number of months, the amount is paid = 48 months
So, the TOTAL amount paid in 48 months
= 48 x ( Amount paid each month) = 48 x ( $250)
= $12,000
So, the TOTAL PRICE of CAR paid = Total amount paid in 48 months + The amount paid for down payment
= $12,000 + $500
= $12,500
Hence, the total cost of the car including the down payment = $12,500
Roxy has some necklaces. Kelly has 4 times more rings than Roxy. Together they have 35. How many necklaces does Roxy have?
Answer:
Roxy has 7 necklaces.
Step-by-step explanation:
35 = n + 4n
35 = 5n
5 = 5
n = 7
The problem is a simple algebra problem related to ratios. By setting up an equation according to the given information, we find that Roxy has 7 necklaces.
Explanation:This is a math problem concerning ratios and simple algebra. Let's denote the number of necklaces that Roxy has as R. Then, Kelly has 4 times more rings, which is 4R. Together they have 35. So, the equation can be set up as:

On a certain hot summer's day, 391 people used the public swimming pool. The daily prices are $1.25 for children and $2.25 for adults. The receipts for admission totaled $752.75. How many children and how many adults swam at the public pool that day?
Final answer:
there were 127 children and 264 adults.
Explanation:
To solve this problem, we use a system of equations. Let's denote the number of children as C and the number of adults as A. We know two facts: the total number of people is 391, and the total amount of money collected is $752.75. Therefore, we have the equations:
C + A = 3911.25C + 2.25A = 752.75To solve this system, we first multiply the first equation by 1.25 to align the coefficient of C with the second equation:
1.25(C + A) = 1.25(391)1.25C + 1.25A = 488.75Next, we subtract this result from the second equation to eliminate C, leaving an equation in terms of A only:
2.25A - 1.25A = 752.75 - 488.75
A = (264) / 1 = 264
Substituting the value of A into the first equation, we find the value of C:
C + 264 = 391
C = 127
Therefore, there were 127 children and 264 adults who swam at the public pool that day.
