Find the missing number of the unit rate. 12/3 = ?/1

Answers

Answer 1

Answer:

the ? would be 4

Step-by-step explanation:

Answer 2

Answer:

4

Step-by-step explanation:

12/3 = ?/1 since these are fraction you can write it like this [tex]\frac{12}{3}[/tex]=[tex]\frac{?}{1}[/tex]

The rules of math says that if 2 fraction are equal like these are then the number diagonal of each other multiplied is equal, like 12×1=3×?

so it means [tex]\frac{12x1}{3}[/tex]= ?  

so  ? is 4

Hope this helps and have a great day!

Answer:

[tex]x = 40[/tex]

[tex]y = 5[/tex]

Step-by-step explanation:

[tex]4x = 2x+80\\2x = 80\\x = 40[/tex]

Edit: Solve for Y

A straight line is 180 degrees so one side (the x side) is 160°, The Y side is 20, and  you can work backwards by -

Which of the following relations has a range of {-8, -6, 4}?
A. {(-8,2), (-6,2), (4,2)}
B. {(-8,2), (-6,4), (2,4)}
C. {(1, -8), (4, -6), (1, -6) (4, -4)}
D. {(1, -8), (4, -6), (1, -6) (5,4)}

Answers

Answer:

D. {(1, -8), (4, -6), (1, -6) (5,4)}

Step-by-step explanation:

The Range of a Relation

Is the set of all second elements of ordered pairs (y-coordinates). Only the elements used by the relation or function constitute the range.

For example, for the ordered pair of a relation (5,2), 5 belongs to the domain and 2 belongs to the range.

Given the range {-8,-6,4} we only have to go through the options and check which one has these values as the second element of the ordered pairs.

Note option D has y-coordinates -8, -6, -6, and 4. Those values correspond to the given range, thus the answer is

D. {(1, -8), (4, -6), (1, -6) (5,4)}

Question 17

Answer: choice C) y = (x-2)^2 - 3

--------------------

Explanation:

We know that a = 1 so it matches with the 'a' value in y = x^2. Otherwise, the shapes wouldn't match up and they wouldn't be congruent.

The vertex we want is (h,k) = (2,-3)

Therefore,

y = a(x-h)^2 + k

y = 1(x-2)^2 + (-3)

y = (x-2)^2 - 3

================================================

Question 18

Answer:  choice B) min point;  -4

--------------------

Explanation:

The equation y = 3(x-1)^2 - 4 is in the form y = a(x-h)^2 + k which is known as vertex form.

a = 3 being positive tells us the graph opens upward and we have a min point. There is no max point as it goes on forever upward.

The min point is k = -4 which is the y coordinate of the vertex.

================================================

Question 19

Answer: Choice B)  y = (1/2)x^2 + 3x - 5

--------------------

Explanation:

The equation opens up, so the value of 'a' must be positive. This narrows our choices to A or B.

We eliminate choice A because that graph is more narrow compared to y = x^2. Choice B is wider and flatter compared to y = x^2 due to 1/2 being smaller than 1.

Answer: 4/5

Step-by-step explanation:

5(y + 2) = 4(x - 3)

Divide each side by 5

5/5(y + 2) = 4/5(x - 3)

(y + 2) = 4/5(x - 3)

Answers

Answer:

15 grams .

Step-by-step explanation:

We need to multiply the percentage as a decimal (0.30) with the amount of chocolate (50 g):

0.30*50 = 15 g

There are 15 grams of cocoa in the chocolate bar.  

Answer:  15 grams of cocoa

Work Shown:

30% = 30/100 = 0.30

30% of 50 = 0.30*50 = 15

Here's another way to think about it: If we had 100 grams of chocolate and 30% are cocoa, then we have 30 grams of cocoa by definition of what percentage means. Divide the 100 in half to get 50, so we'll have to divide the 30 in half to get 15.
