Find the supplement to the angle whose measure is 70 degrees. Show all your work

Answers

Answer 1
Answer: Supplementary angles add up to 180 degrees. Suppose the supplement of 70 degrees is x.
therefore the sum of our angles will be:
x+70=180
solving for x we get:
x=180-70
x=80°
hence the value of the supplement of 70° is 80°

Answers

Answer:

x = 5.142

Step-by-step explanation:

2=-74+14x

if you want to make x the subject (work out its value), you need to single out x

1) the first thing that we can do is get rid of the -74

2) do this by adding it on to both sides of the equation. This is called the inverse

2+-74=-72   -74+14x=14x

-72=14x

3) to get x on its own, we now need to get rid of the 14

REMEMBER: 14x = 14×x

4) We do the inverse by dividing both sides by 14

-72÷14=-5.142...

its surprising that its not an integer

5.142=x

x=5.142

Nika baked three cakes. Each cake needed 17/4 cups of flour. Which expression shows the best estimate of the number of cups of flour that Nika used? A. 4 + 4 + 4 = 12
B. 5 + 5 + 5 = 15
C. 4 + 4 + 4 = 16
D. 17 + 17 + 17 = 51

Answers

First we need to find out what 17/4 is.

17/4 = 4 1/4
so each cake needs 4 1/4 cups of flower.

Now, the question asks what the best estimate of the total number of cups is.

It could be A or C because 4 1/4 is closer to 4, but...
we need to figure out if 4 1/4 + 4 1/4 + 4 1/4 (we need to make three cakes) is closer to 12 or 16.

4 1/4 + 4 1/4 + 4 1/4 = 12 3/4

Ask yourself: is 12 3/4 closer to 12 or 16?


12 3/4 is closer to 12 so the answer is A.

Answer:

A

A wheel made 45 revolutions in 1 minute. At that rate, how many revolutions would it make in 15 minutes?

Answers

A wheel would make 675 revolutions in 15 minutes.

Since the wheel makes 45 revolutions in 1 minute, and the problems asks how many revolutions it would make in 15 minutes, you would multiply the rate by the time:
45*15=675.

Answers

Answer:

Option B is correct! Because for the x=2, there are two y values. Below is a detailed explanation.

Step-by-step explanation:

Function:

    A function does not have two different outputs(y) for the same input(x).

Let's analyze each option.

For option A:

 The x values are {0,2,4,-2,5}

Here none of the x values are repeated.

So, it represents a function.

For option B:

   The x values are {0,2,4,2,5,7}

Here the x value '2' is repeated two times.

According to the explanation of the function, when x=2, the 'y' can not be equal to 2, 7.

So, this is not a function.

IT is b because you cant repeat a number in the (x) for it to be a function. 2 is repeated.
