I feel like I'm trying to hard on this one but here we go, On a number line what is the distance between 2/5 and 5/6?
Answer:
The answer is [tex]\frac{13}{30}[/tex].
Step-by-step explanation:
Solve by completing fraction division.
Thus, solve [tex]\frac{5}{6} - \frac{2}{5}[/tex], since [tex]\frac{5}{6}[/tex] is larger than [tex]\frac{2}{5}[/tex].
[tex]\frac{5}{6} - \frac{2}{5}[/tex]
[tex]= \frac{25}{30} - \frac{12}{30}[/tex]
[tex]= \frac{13}{30}[/tex]
Hence, the answer is [tex]\frac{13}{30}[/tex].

5. About 0.36 of the students at a middle school are seventh graders.
a. What fraction of the students at the middle school are not seventh graders?
b.There are equal numbers of sixth and eighth graders at the middle school. What percent of the students at the middle school are sixth graders?
Answer: 18 sixth graders
Step-by-step explanation:
Let
x-----> the number of sixth graders in the band
y-----> the number of seventh graders in the band
we know that
-----> equation A
------> isolate the variable y
-----> equation B
Substitute equation B in equation A
x+ (1.5x) = 45
2.5x=45
x=45/25= 18 sixth graders
Answer: A. 9/14 B. 8/25.

58 x 4/8
Answer: 29
Step-by-step explanation:
[tex]58*\frac{4}{8} =\frac{58*4}{8} =\frac{232}{8} =29[/tex]
[tex]\boldsymbol{\sf{58*\dfrac{4}{8} }}[/tex]
We reduce the fraction 4/8 to its lowest expression by extracting and canceling 4.
[tex]\boldsymbol{\sf{\dfrac{4}{8}=\dfrac{4\div4}{8\div2}=\dfrac{1}{2} }}[/tex]
[tex]\boldsymbol{\sf{58\times\left(\dfrac{1}{2}\right) }}[/tex]

Answer:
8) 24 meters
9) 50.75 feet
10) 166 meters
Step-by-step explanation:
8) the perimeter is the sum of all sides of your shape. The shape is a rectangle, so you know 2 sides are the same length, 16.3 meters, and the other two sides are the size of the width, that is asked for.
so the perimeter = 2*length + 2*width which gives you the equation
80.6 = 2*16.3 + 2*x
then you solve it this way:
80.6 = 32.6 + 2x | substract 32.6 on both sides
48 = 2x | divide by 2 on both sides
24 = x
so you know the width is 24 meters
9) again, the perimeter is the sum of all 3 sides of your triangle.
2 sides are each 36 and 3 quarters feet long.
so the equation is perimeter = 2*36 3/4 + unknown side, giving you the equation
124 1/4 = 2 * (36 3/4) + x
124.25 = 73.5 + x | substract 73.5 on both sides
50.75 = x
so the third side is 50.75 feet (or in other writing 50 and 3/4 feet)
10) so on the image you see that the park is a triangle. you are given the area and one side (along Second Ave) and you need to figure out the length of the side along Front Street. When you "double" the triangle, you get a rectangle.
The area of the imagined rectangle is 2 times the area of the triangle (the park), so the area of our rectangle is 13778.
The area of a rectangle is calculated width * length.
This gives you the equation
13778 = 83 * x | divide both sides by 83
166 = x
So the length of the park along Front Street is 166 meters.
A new health drink has 130% of the recommended daily allowance (RDA) for a certain vitamin. The RDA for this vitamin is 20 mg. How many milligrams of the vitamin are in the drink?
Answer: 58.5 milligrams
Step-by-step explanation:
Answer:
58.5 mg
Step-by-step explanation:
Drink: 130% of RDA of vitamin X
RDA vitamin X = 45 mg
130% of 45 = mg in the drink
130% = 130/100 = 1.3
130% of 45 = 1.3 * 45 = 58.5
Thus, this new drink has 58.5 mg of vitamin.

A car salesperson earns a monthly salary of $800 per month plus $250 for each car sold. The equation y = 250x + 800 represents the total monthly salary. Graph the equation using the slope and y-intercept.
Answer:x - the total sales
800 + 0.02 x ≥ 1600
0.02 x ≥ 1600 - 800
0.02 x ≥ 800
x ≥ 800 : 0.02
x ≥ 40,000
The total sales must be at least $40,000.
The graph of the equation using the slope and y-intercept is shown in image.
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
A car salesperson earns a monthly salary of $800 per month plus $250 for each car sold.
Here, The equation y = 250x + 800 represents the total monthly salary.
Hence, Slope is,
⇒ m = 250
And, Y - intercept = 800

What is an estimate?
An estimate is a rough calculation based on available information or rounded-off data.
Estimates are made to enable quick decisions without knowing complete details.
For this estimate, we used the division operation to obtain the quotients that should be the share of receiving families from each food category.
Original Data:
Food Item Number of Pounds Number of Families
Available Receiving Item
Chicken rolls 113.4 9
Mashed potatoes 6.6 12
Corn 28.5 10
Green bean 18.92 11
Casserole 5.37 3
Thus, as much as possible, some pounds of food items have been rounded to enable the estimate to be produced.
