Jeremiah has $7 to spend at the school store. He definitely wants to buy a Sprite for $1.50 and wants to use the rest of his money to buy as many packs of gummy worms as possible. If the gummy worms are on sale for $0.27 each, how many packs can Jeremiah buy?
Answer:
Step-by-step explanation:
Amount with Jeremiah = $7
Cost of Sprite = $1.50
Amount remaining = Amount with Jeremiah - Cost of Sprite
= $7 - $1.50
= $5.50
Gummy worms cost = $0.27 each
Number of gummy worms he can purchase = $5.50 / $0.27
= 20.37
Jeremiah can buy as many as 20 packs of gummy worms
7. Find the equation of a line in slope intercept form that is parallel to the line below that goes through the point (6, 4). y = fx-5
Answer:
y=3/2x-5
when finding the equation of a line, we use this formula
y=mx+b
where Y= a point on the y-axis
M= ∆y/∆x
x= a point on the x-axis
and b = intercept
Step-by-step explanation:
so to in this case, we are given y= 4, x=6 and y-int = -5
substitute the value in the given equation,
therefore, 4=6m-5
4+5=6m
9/6=M
3/2=m
Answer y=3/2x-5 that is the equation of the line

At an important meet, Rosalva won the women’s 100 meters in 13.47 seconds. Rosalba ran at an average rate of _ meters per second .
Answer:
about 7.42 meters per second
Step-by-step explanation:
speed = distance/time
Rosalba moved at a speed of 7.27 meters per second on average.
What is Speed?speed is described as. the pace at which an object's location changes in any direction. Speed is defined as the distance traveled divided by the travel time. Speed is a scalar quantity because it just has a direction and no magnitude.
Given, At an important meet, Rosalva won the women’s 100 meters in 13.47 seconds.
From the general formula of speed:
Speed = distance/time
In our case,
Distance= 100 meters
time = 13.74
Thus,
Speed = 100/ 13.74
Speed in meters per second = 7.27
therefore, Rosalba ran at an average rate of 7.27 meters per second.

Alana bought some cans of paint and 1/2 of a liter of special paint additive formulated to reduce mildew. Before painting her house, she used all of the additive to put 1/8 of a liter of additive in each can. How many cans of paint did Alana buy?
Answer:
Alana bought 4 cans of paint additive
Step-by-step explanation:
Proportions
If a proportional amount of x is to be distributed between y elements, each one of them gets x/y portions.
For example, if we have 100 coins and distribute evenly between 20 boxes, each box will receive 100/20=5 coins.
Alana bought 1/2 of a liter of the special paint additive and evenly distributed it between an unknown number of cans, let's call it C. We also know each can received 1/8 of a liter of the additive. That is the proportion of the 1/2 liter of additive.
We can establish the following condition:
[tex]\displaystyle \frac{1/2}{x}=\frac{1}{8}[/tex]
Solving for x:
[tex]\displaystyle \frac{1/2}{\frac{1}{8}}=x[/tex]
Transform the division into a product:
[tex]\displaystyle x=\frac{1}{2}\cdot\frac{8}{1}=4[/tex]
Alana bought 4 cans of paint additive

The diagonal lengths of three rectangles are shown . The rectangles are not drawn to scale . Which list shows the rectangles in order by their diagonal lengths from shortest to longest ?
Answer:
B. Rectangle T, Rectangle P, Rectangle S.
Step-by-step explanation:
To determine which list shows the correct order of the length of the diagonals of the rectangles from shortest to longest, let all the lengths be in decimal form:
Rectangle P = 6.7 cm
Rectangle S = [tex] \frac{34}{5} cm [/tex] = 6.8 cm
Rectangle T = [tex] \sqrt{36.5} cm [/tex] ≈ 6.04
Thus:
6.04 cm < 6.7 cm < 6.8 cm
Therefore, from the shortest to the longest, we have:
Rectangle T < Rectangle P < Rectangle S.

Line PQ is located in the coordinate plane with point P at(-2,-2)
and point Q at (0,7). Point R is located at (3, 0). For what coordinates of point S will lines PQ and RS be parallel?
(5,9)
(9,5)
(5. – 1)
(1-1,5)
Answer:
The coordinates of point S are (5, 9) will make line PQ // line RS ⇒ A
Step-by-step explanation:
Parallel lines have the same slopes
The slope of a line = Δy/Δx, where
Δ y is the change of yΔ x the change of xLet us first find the slope of the line PQ.
∵ P = (-2, -2) and Q = (0, 7)
∴ Δx = 0 - (-2) = 0 + 2 = 2
∴ Δy = 7 - (-2) = 7 + 2 = 9
∴ The slope of PQ = 9/2
∵ Line PQ // line RS
∴ The slope of line PQ = the slope of line RS
∴ The slope of line RS =9/2
∵ Point R = (3, 0) and point S = (x, y)
∵ The slope of line RS = 9/2
∵ The slope = Δy/Δx
∴ Δy/Δx = 9/2
→ That means Δy = 9 and Δx = 2
∵ Δy = y - 0
∵ Δy = 9
∴ 9 = y
∵ Δx = x - 3
∵ Δx = 2
∴ 2 = x - 3
→ Add 3 to both sides
∴ 2 + 3 = x - 3 + 3
∴ 5 = x
∴ The coordinates of point S are (5, 9) will make line PQ // line RS

A racing car consumes a mean of 101 gallons of gas per race with a variance of 49.
If 43 racing cars are randomly selected, what is the probability that the sample mean would differ from the population mean by greater than 2.4 gallons? Round your answer to four decimal place
Answer:
The probability that the sample mean would differ from the population mean by greater than 2.4 gallons is 0.86558
Step-by-step explanation:
The given parameters are;
The mean, [tex]\bar x[/tex] = 101 gallons
The population mean = μ
The variance, σ² = 49
The number of racing cars, n = 43
The probability that the sample mean would differ from the population mean by greater than 2.4 gallons is given as follows;
P([tex]\left | \bar x - \mu \right |[/tex]) >2.4 = P(2.4 > [tex]\left | \bar x - \mu \right |[/tex] >-2.4)
The formula for the test of the mean, Z₀, is given as follows;
[tex]Z_0 = \dfrac{\bar x - \mu}{\dfrac{\sigma}{\sqrt{n} } }[/tex]
Therefore, we have;
[tex]P \left (\dfrac{2.4}{\dfrac{\sqrt{49} }{\sqrt{43} } } >Z> \dfrac{-2.4}{\dfrac{\sqrt{49} } {\sqrt{43} } } \right) = P \left (\dfrac{2.4}{\dfrac{7 }{\sqrt{43} } } >Z> \dfrac{-2.4}{\dfrac{7} {\sqrt{43} } } \right)[/tex]
Which gives;
P([tex]\left | \bar x - \mu \right |[/tex]) >2.4 = P(2.25 > Z > -2.25)
(We round up to 2.25 because that is the accuracy of the z-table)
From which we have;
P(Z > -2.25) - P(Z > 2.25) = (1 - P(Z < -2.25)) - (1 - P(Z < 2.25))
P([tex]\left | \bar x - \mu \right |[/tex]) >2.4 = (1 - 0.1222) - (1 - 0.98778) = 0.86558
The probability that the sample mean would differ from the population mean by greater than 2.4 gallons = 0.86558.
is the fraction 11/20 a repeting and termnating decimal?
Answer:
it is terminating
Step-by-step explanation:
Answer:
11/20 is a terminating decimal.
Step-by-step explanation:
1) Find the denominator of 11/20 in its lowest form.
The greatest common factor (GCF) of 11 and 20 is 1. Convert 11/20 to its simplest form by dividing the numerator and denominator by its GCF: The denominator of 11/20 in its lowest form is 20.
11 ÷ 1 / 20 ÷ 1 = 11 / 20
2) Find the prime factors of the answer in Step 1.
The prime factors of 20 are all the prime numbers that you multiply together to get 20. The prime factors of 20 are:
2 x 2 x 5
3) Determine if 11/20 is terminating.
A fraction is a terminating decimal if the prime factors of the denominator of the fraction in its lowest form only contain 2s and/or 5s or no prime factors at all. This is the case here, which means that our answer is as follows:
11/20 = terminating.

A student in the Construction Trades program at the Cecil County School of Technology has 4 1/2gallons of paint. If he uses 2.75 gallons of the paint in one room, how many gallons of paint are left? Show your work on your paper and write your final equation and correct answer in the box below.
Answer:
1.75 gallons of paint
Step-by-step explanation:
A student in the construction trades program has 4 1/2 gallons of paint
If the student uses 2.75 gallons in one room then the gallons of paint that are left can be calculated as follows
= 4 1/2 - 2.75
= 9/2 - 2.75
= 4.5 - 2.75
= 1.75
Hence 1.75 gallons of paint are left

What’s the solution to f
Answer:
65
Step-by-step explanation:
Answer:
f = 65
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
201.5 = f + 136.5
Step 2: Flip the equation.
f + 136.5 = 201.5
Step 3: Subtract 136.5 from both sides.
f + 136.5 − 136.5 = 201.5 − 136.5
f = 65
