Kevin walked Three-fourths of a mile in 12 minutes. Assuming he walked at a constant speed the entire time, which expression can be used to determine the distance he walked each minute?
12 divided by three-fourths
12 times three-fourths
Three-fourths divided by 12
Four-thirds divided by 12
Answer:
Your answer would be C.
Step-by-step explanation:
The expression that can be used to determine the distance he walked each minute is x = 12/(3/4) miles option (A) is correct.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
Kevin walked Three-fourths of a mile in 12 minutes. Assuming he walked at a constant speed the entire time.
As we know,
The distance = speed x time
Speed is constant
distance ∝ time
3/4 ∝ 12
1 ∝ x
Here x is the distance traveled each minute
3/4 = 12/x
Or
x = 12/(3/4)
1/4 = 4/x
x = 16 miles
Thus, the expression that can be used to determine the distance he walked each minute is x = 12/(3/4) miles option (A) is correct.

Answer:
n + 3m + 2, or also the same as 1n + 3m + 2
The simplified form of the given expression is [tex]n+2+3m[/tex].
Important information:
The given expression is [tex]\dfrac{1}{2}(2n+4+6m)[/tex].Distributive Property:[tex]a(b+c)=ab+ac[/tex]
We have,
[tex]\dfrac{1}{2}(2n+4+6m)[/tex]
Using the Distributive Property, the given expression can be written as:

Step-by-step explanation: A hexagon has six sides and six angles. A regular pentagon has five sides and five angles. A regular hexagon has six sides and six angles. An isosceles triangle has three sides and three angles. A triangle has three sides and three angles. A square has four sides and four angles. Hexagon: the prefix hexa- means six. Regular pentagon: the prefix penta- means five. Regular hexagon: the prefix hexa- means six. Isosceles triangle: the word tri-angle literally means three-angle, and all triangles have three sides. Triangle: the word tri-angle literally means three-angle, and all triangles have three sides. Square: a square is a Quadrilateral, which means it has four sides and four angles.

Jacob sells homemade skateboard decks for a profit of $27 per each one. He is considering switching to a new type of material that will increase his profit (y = 32x0) (where x is the number sold and y is the amount of profit).
How many more dollars will Jacob earn on each skateboard deck if he switches to the new material?
(Please Explain)
Answer:
I believe it is 32
Step-by-step explanation:
I think this because in your equation it says (y=32x) which 32 will mean how much he is charging for each skateboard, x will be how many he sells, and y would be how much he makes from selling them. So if he sold 2 skateboards you would do.. 32 x 2 which equals 64 soo that would be (64=32x2) so it is 32
Jacob will earn more for each skateboard deck if he switches to the new material is $5.
What is profit?When something or the cost of manufacturing an object is less than the selling price of the object, then you get a profit.
As it is given that Jacob will increase his profit by 32x where x is the number sold means he will get $32 if he sold one product (32×1).
Before, he gets a profit of $27 if he sold one skateboard, so,
Let Jacob will earn y amount more than the current material,
y = Profit in new material - Profit in old material
y = 32 - 27
y = $5
Therefore, Jacob will earn more for each skateboard deck if he switches to the new material is $5.

A conversion table indicates that 1 mile is 1.6 km. With this conversion rate, is the speed limit greater than or less than 65 mph? Explain.
greater because 1.6 is larger than 1
Answer:
higher than
Step-by-step explanation:
The speed limit is 110 km hour and there are 1.6 kilometers in a mile. This means that there are 110 ÷ 1.6 miles per hour:
110 km hour÷1.6 km mile=110÷1.6 miles hour.
We can find 110 ÷ 1.6 using long division and it is 68.75. So the speed limit is higher than 65 mph

Containers of oats are prepared in advance for a baking project. Later, raisins are added to the oats to make granola bars. This table shows the rate relationship between oats and raisins.
Cups of Oats (x) Cups of Raisins (y)
1
0.5
2
1
3
1.5
4
2
5
2.5
Which answer choice includes both a function that describes this relationship and correctly explains how?
y = 2 x, because the recipe calls for a ratio of 2 cups raisins per cup of oats.
y = x , because the recipe calls for a rate of 1/2 cup raisins per cup of oats.
y = x , because the recipe calls for a rate of 2 cups raisins per cup of oats.
y = 2 x, because the recipe calls for a rate of 1/2 cup raisins per cup of oats.
Answer:
2y=x
For every two cups of oats there's one cup of raisins.
Step-by-step explanation:
1÷2=0.5
2÷2=1
3÷2=1.5
4÷2=2
5÷2=2.5
