3. (c= constant of proportionality)
c= [tex]\frac{distance}{time}[/tex]
c=[tex]\frac{90 miles}{2 hours}[/tex]
c= 45 miles per hour
Step-by-step explanation:
So you may see for each hour they are going 45 miles by dividing 2 by 2 and 90 by 2, so there constant of proportionality is 45 miles per hour. (answer 3 is the step by step)

According to the frequency table, what is the mean of the score?
Round your answer to the nearest tenth.
A) 6.0
B) 6.1
C) 6.2
D) 6.3
The mean of the scores is approximately 6.2. The correct answer is (C).
What is arithmetic mean?The arithmetic mean is defined as the ratio of the sum of observations to the total number of observations. It can be referred to as the average of a specific set of data or the arithmetic mean.
To calculate the mean of the scores based on the given frequency table, we need to multiply each score by its corresponding frequency, sum up the results, and then divide by the total frequency.
Let's perform the calculations:
(1 x 1) + (2 x 1) + (3 x 3) + (4 x 1) + (5 x 4) + (6 x 5) + (7 x 6) + (8 x 5) + (9 x 3) + (10 x 1) = 167
1 + 2 + 9 + 4 + 20 + 30 + 42 + 40 + 27 + 10 = 185
The total frequency is 1 + 1 + 3 + 1 + 4 + 5 + 6 + 5 + 3 + 1 = 30
Now, we divide the sum (185) by the total frequency (30) to find the mean:
185 / 30 = 6.1667
Rounding this value to the nearest tenth, the mean of the scores is approximately 6.2.
Therefore, the answer is C) 6.2.

Answer:
The Stores profit is 70% or $59.5
How?
The reason is because if it's selling it for 100% of the price, then that means that the store bought it for 85 dollars, and it's selling it for 85 dollars, and that's 0% profit. But because the store has bought it for 100%, and then it's charging another 70% of the price, so the store's profit is 70%.
Now, we find 70% of 85 dollars, which will be the STORE'S PROFIT AMOUNT!
1. Convert percentages into fractions or decimals
For fraction: divide 70 by 100 and remove the % sign.
[tex]{70}\%=\frac{70}{100}[/tex]
For decimal: move the decimal point 2 places to the left and remove the % sign.
[tex]{70}\%=0.7[/tex]
2. Multiply the decimal or fraction by the quantity that equals 100%
[tex]100[/tex]%[tex]=85[/tex]
[tex]\frac{70}{100} *85=0.7*85=59.5[/tex]
70% of 85 is 59.5Store's profit is $59.5Extra info:
170% of 85 = 144.5
70% of 85 = 59.5

question: the solutions of a quadratic equation are x=-7 and 5. which could represent the quadratic equation and why?
Answer:
B) x²+2x-35=0; the factors are (x+7)(x-5)
Step-by-step explanation:
The quadratic equation which has the solutions as x = -7 and 5 may be x² + 2x - 35 = 0, the factors are (x + 7) and (x - 5) and (x + 7)(x - 5) = x² + 2x - 35.
What are Quadratic Equations?Quadratic equations are polynomial equations of second degree.
The general form of a quadratic equation is ax² + b x + c = 0.
Given that,
a quadratic equation has the solutions x = -7 and 5.
There are two options, x² + 2x - 35 and x² - 2x - 35
Using the factorization method, a quadratic equation ax² + b x + c = 0 can be factored as (x + p)(x + q) where pq = c/a and p + q = b/a.
Consider, x² + 2x - 35 = 0
There are numbers 7 and -5 that 7 - 5 = 2 and 7 × -5 = -35
So it can factored as,
(x + 7) (x - 5) = 0
Solutions are x = -7 and x = 5
Hence the quadratic equation is x² + 2x - 35 = 0.

Harper wants to put wood shavings in her rabbit's cage. The floor of the cage measures 1 yard wide by 6 feet long. One bag of shavings cover 10 square feet.
How many bags will Harper have to buy to cover the floor of the cage? Explain
Harper will have to buy _____ bag(s) to cover the floor because the area of the floor is _____ square foot/feet.
Help please :-(
Answer:
she would need 2 bags because it is 18 but covers 10 square feet
Step-by-step explanation:
Width = 1 yard = 3 feet
Length = 6 feet
Square feet(area) of the floor = 6ft × 3ft = 18sqft
1 bag = 10sqft
x bag = 18 sqft
x bags = (18 × 1)/10
= 1.8 bags

The members of the gardening group plan to build a walkway through the garden as formed by the hypotenuse of each of the four triangles in the drawing. That way, the gardeners will be able to access all sections of the garden. Calculate the length of the entire walkway to the nearest hundredth of a yard. Show your work. (4 points—1 point for each length calculation and 1 point for the total distance)
Is the value you just wrote for the total length of the walkway a rational or irrational number? Explain. (2 points)
Answer:
1) The length of the entire walkway to the nearest hundredth of a yard is 50.24 yds
2) 50.24 is a rational number
Step-by-step explanation:
1) To calculate the length of the walkway, you need to find "b"
the value of b using the Pythagoras theorem can be written as,
D²=12²+b²
15²=12²+b²
225=144+b²
b²=81
b=9
the value of each of the four hypotenuses can be written as,
A = [tex]\sqrt{12^2+8^2}[/tex] = [tex]\sqrt{208}[/tex] = 14.422
B = [tex]\sqrt{6^{2} +8^{2} }[/tex] = [tex]\sqrt{100}[/tex] = 10
C = [tex]\sqrt{6^2+9^2}[/tex] = [tex]\sqrt{117}[/tex] = 10.82
D = 15
Adding the value of all the hypotenuse to get the length of the walkway, therefore, the length will be,
14.422 + 10 + 10.82 + 15 = 50.24
So, the entire walkway to the nearest hundredth is 50.24
2) Because Irrational numbers are ones that never end.
50.24 is a nice, round number, even though its a decimal.
Answer:
50.24 - rational number

Answer:
68 in³
Step-by-step explanation:
To find the volume of the figure, we first need to find the volumes of the 2 triangular prisms and 1 rectangular prism.
Triangular prism
[tex]{\boxed{\text{Volume}= \text{base area ×height}}}[/tex]
The base area here is the area of the triangular face, since it is the face that repeats itself throughout the entire length/height to form the volume of prism.
Base area
= area of triangle
= ½(base)(height)
= ½(2)(3)
= 3 in.
Height= 2 in.
Volume
= 3(2)
= 6 in³
Volume of rectangular prism
Volume
= base area ×height
= length ×breadth ×width
= 14(2)(2)
= 56 in³
Total volume
Volume of figure
= 2(6) +56
= 12 +56
