So how are 1/2 and 4/8 Similar?
Answer:They both equal 1 half
Step-by-step explanation:To put it a lil more simply, 1/2 = 0.5 and 4/8 also = 0.5
Answer:
1/2 is 4/8. 1/2 is just 4/8 but simplified. So 12/36 simplified is 1/3, 24/48 is 1/2
Sample Response/Explanation: No. The correct values of a, b, and c were substituted in, but the formula was simplified wrong. The 64 should be added so the radicand is 73. There should be 2 real roots.
Which of the following did you include in your response? Check all of the boxes that apply.

Use distributive property to write an expression that is equivalent to 6(10x+7y)
60x + 42y
60x +42y
60x +42y
The distributive property of 6(10x + 7y) is 60x + 42y
What is distributive property ?Distributive property tells us the order of operations to be followed by us while doing mathematical operations. the order of operations laid by distributive property is given below in chronological order:
1. Solve the brackets.
2.Orders(Exponents and square roots)
3. Division
4. Multiplication.
5.Addition
6. Subtraction
Now using Distributive property on 6(10x+7y)
1. Solve the brackets:
We can't do anything with the part inside the bracket as it contains all unknown values.
Hence, it will be as it is.
6 × 10x + 6 × 7y
2. Orders:
Whenever the index of any term is not shown, it is 1.
If any number is not multiplied by itself, it can be raised to 1.
3. Division:
The given polynomial doesn't have division with a non one number.
4. Multiplication:
6 × 10x + 7 × 7y
60x+42y
5. Addition:
Indefinite values can't be added
60x+42y
6. Subtraction:
No sign of subtraction is seen
Hence ,the distributive property of 6(10x + 7y) is 60x + 42y

The amount a hardware store pays for buying nylon rope is represented by the equation y = 0.08x, where 'y' is the price it pays for 'x' feet of rope. The amount the hardware store charges for selling the rope is represented by the graph. Part A What does the slope of the graph show about the hardware store's selling price for the rope?
Answer:
0.025 $/in.
The store bought 300 ft of rope.
1 ft = 12 in.
300 ft * 12 in./ft = 3600 in.
The store bought 3600 inches of rope.
The store sells 40 inches of rope for $1.60. We can find the selling unit price of rope in dollars per inch.
($1.60)/(40 in.) = $0.04/in.
The store sells the rope at a price of $0.04 per inch.
The store sold all the rope at $0.04/in.
3600 in. * $0.04/in. = $144
The store sold all the rope for $144.
The profit was $54 for selling ll the rope.
$144 - $54 = $90
The bought the rope for $90.
The cost is dollars per inch is
($90)/(3600 in.) = 0.025 $/in.
Step-by-step explanation:
The slope tells for every one-foot increase in the amount of rope sold, the hardware store increases the selling price by $0.08.
The slope of the graph represents the rate of change between the hardware store's selling price (y-axis) and the quantity of nylon rope sold (x-axis).
In this case, the slope is given as 0.08.
Interpreting the slope:
A slope of 0.08 means that for each additional foot of nylon rope the hardware store sells (x increases by 1), the selling price (y) increases by $0.08.
This indicates a linear relationship between the quantity of rope sold and the selling price.
In other words, for every one-foot increase in the amount of rope sold, the hardware store increases the selling price by $0.08.

the bellah's pool is leaking. The pool leaked 3/4 gallon in 20 minutes, or 1/3 hour. how many gallon is the pool leaking each hour?
Answer:
9/4 gallons
Step-by-step explanation:
If the rate is 3/4 gallon per 1/3 of an hour, we need to figure out how to make the 1/3 into 1 hour.
Since it's 1/3, you have to multiply it by 3 to get 1. So, multiply 1/3 and 3/4 by 3:
The rate will be 3(3/4) gallons per 3(1/3) hour
The rate will be 9/4 gallons per 1 hour

A 90
B 21
C 34
D 25
Answer:
C 34
Step-by-step explanation:
f(x) = 15x + 4 x = 2
f(x) = 15(2) + 4
f(x) = 30 + 4
f(x) = 34
Answer:
Your answer is C. 34
Step-by-step explanation:
Solve f(x) = 15x + 4 where x = 2
f(x) = 15x + 4
Substitute:
f(2) = 15(2) + 4
Multiply:
f(2) = 30 + 4
f(2)= 34

To find the distance that each member ran, Balin wrote the expression below. StartFraction 5 Over 6 EndFraction divided by 10 Which expression is equivalent to Balin's expression?
Answer:
The equivalent expression = 1/12 of a mile
Step-by-step explanation:
Total distance of 10 members of the Balin's soccer club =5/6 of a mile
To find the distance that each member ran, Balin wrote the expression:
5/6 ÷ 10
Which expression is equivalent to Balin's expression?
5/6 ÷ 10
= 5/6 × 1/10
= 5/60
= 1/12 of a mile
