Noah’s recipe for sparkling orange juice uses 4 liters of orange juice and 5 liters of soda water.
Sometimes the school purchases a certain number, , of liters of orange juice and Noah needs to figure out how much sparkling orange juice he can make. Write an equation that Noah can use to find if he knows .
Answer:
Let a be the number of liters of orange juice
Total number of liters of sparkling juice, t = liters of orange juice + liters of soda water
= 4a + 5 × S
Since a = S,
t = 4S + 5S
t = 9S
S = t/9

Answer:
Answer In Explanation
Step-by-step explanation:
O More Than Half Of The Students Scored 81 Or Better
O The Same Number Of Students Scored Between 81 And 90 On The Test As Scored Between 61 And 80
-The Last One Is Confusing Because It Doesn't Say 71-80
Options (B) and (D) are true statements that describe the data in the histogram are the correct answers.
What is a histogram?A histogram is a visual way to display frequency data using bars. It is a chart that shows frequencies for intervals of values of a metric variable. It is a display of statistical information that uses rectangles to show the frequency of data items in successive numerical intervals of equal size.
For the given situation,
The histogram shows the scores on a recent science test.
We need to check the options, which statements describe the data.
Option A: Only two students scored less than 71 on the test.
There are four students scored less than 71.
So option A is false.
Option B: More than half of the students scored 81 or better on the test.
Students scored more than 81 = [tex]16+8[/tex]
⇒ [tex]24[/tex]
Total number of students = [tex]40[/tex]
Half of the students = [tex]\frac{40}{2}[/tex]
⇒ [tex]20[/tex]
Thus, [tex]24 > 20[/tex]
So option B is true.
Option C: More students scored between 91 and 100 on the test than scored between 71 and 80.
Students scored between 91 and 100 = [tex]8[/tex]
Students scored between 71 and 80 = 12
⇒ [tex]8 < 12[/tex]
So option C is false.
Option D: The same number of students scored between 81 and 90 on the test as scored between 61 and 80.
Students scored between 81 and 90 = [tex]16[/tex]
Students scored between 61 and 80 = [tex]4+12[/tex]
⇒ [tex]16[/tex]
Thus, [tex]16=16[/tex]
So, option D is true.
Option E: There were 12 students who scored 80 on the test.
The score range is between 71 to 80. So we could not predict the number of students who score 81.
So option E is false.
Hence we can conclude that options (B) and (D) are true statements that describe the data in the histogram are the correct answers.

The total surface area of the prism is 74 square meters, Option C is correct.
What is Area of Rectangle?The area of Rectangle is length times of width.
In the given figure there are 3 rectangles.
Area of rectangle is length times width
Length is 5m and width is 4m
Area of rectangle = 5×4
=20 square meters
Area of three rectangles = 3(20)
=60 square meters
There are four right triangles, base is 2m and height is 3.5 m
Area of rectangle = 1/2 × 2× 3.5
=3.5 square meter
As there are 4 right triangles 4(3.5)
Area of 4 right triangles is 14 square meters
Total surface area = 60+14
=74 square meters
Hence, the total surface area of the prism is 74 square meters, Option C is correct.

The diameter of a dime is 17.9 millimeters. What is the area of one side of the coin? Show your work
Answer: I think 612 millimeters
Answer:
251.65 Millimeters rounded to the hundredths place.
Step-by-step explanation:
The formula for the area of a circle is A=π×r^2.
Step 1: Find r, or the radius, which is half the diameter. In this case, it is 8.95.
Step 2: Square the radius that you get. In this case, the answer is 80.1025.
Step 3: Multiply the past number by π on your calculator. Some teachers allow 3.14 but be certain that your teacher allows it. In this case, π×80.1025=251.649425534
Step 4: You've got your answer! Hope this helps!

Jacob is painting a circular picture on his wall. If the painting
has a diameter of 4 ft, how much paint will he need to cover the
inside of the circle? Is this question asking you to find the area,
circumference, or neither?
A. area
B. neither
C. circumference
The question is asking to find the amount of paint needed to cover the inside of the circular picture with a diameter of 4 ft. To determine the amount of paint required, we need to calculate the area of the circle.
The options provided are:
A. areaB. neitherC. circumferenceSince we are calculating the amount of paint needed to cover the inside of the circle, the question is asking to find the area. Therefore, the correct answer is A. area.
The diameter of a circle is a straight line segment that passes through the center of the circle and connects two points on the circumference, effectively dividing the circle into two equal halves.
In the context of the given question, it states that the circular picture has a diameter of 4 ft. This means that the distance from one side of the circle to the other, passing through its center, measures 4 ft.
The diameter is an important measurement when calculating various properties of a circle, such as its area and circumference.

In the given figure, can you conclude r || s?
A. The lines are parallel because the given angles are same-side interior angles and their sum is 180°.
B. The lines are parallel because the given angels are alternate interior and they are supplementary.
C. The lines are not parallel because the given angles are corresponding angles and they do not have equal angle measures.
D. There is not enough information.
Answer:
The answer is C.
Step-by-step explanation:
The photo depicts corresponding angles (one angle above the other, as shown). When two lines are parallel, there will be corresponding angles that are the same measure. If they don't match, one line will be at a tilt and eventually intersect the other - therefore not parallel. Hope this helps!

44/100
0.44
44%
Step-by-step explanation:
Okay so fraction is easy, theres a 100 cubes in total, 44 are shaded in, 44/100 are shaded in which is the area in this scenario.
Decimal is basically moving the place area by a specific amount, in this case theres no whole number since the whole number is 1 or 100/100 and its 44/100 right now so it can’t be a whole number. Decimals go by tenths, hundreths, thousandths, etc. so in this case 44/100 is n the hundreth place since its over a hundred so its 0.44. Or you can move it twice to the right by the times of 0 that appears.
Percent basically means out of 100. So in this case its 44 out of a hundred or 44%

Lin also looks at the box. She says: “I think the number of paper clips in the box is more than 500.”
Write an inequality to show Andre's statement, using p for the number of paper clips.
Write another inequality to show Lin's statement, also using p for the number of paper clips.
Do you think both Lin and Andre would agree that there could be 487 paperclips in the box? Explain your reasoning.
Do you think both Lin and Andre would agree that there could be 742 paperclips in the box? Explain your reasoning.
Answer:
andre: p<1000
Lin: p>500
they would not agree that there are 487 paperclips because both of there guesses are greater than that. they would both agree that there are 742 paperclips because 742 is greater than 500 but less than 1000.
