Help And Explain Dont Use For Points Or I Will Take It Back

Answers

Answer 1

Step-by-step explanation:

step 1. x + 51 + 39 + 127 = 360 (1 revolution is 360°)

step 2. x + 90 + 127 = 360

step 3. x + 127 = 270. (subtract 90 on both sides)

step 4. x = 143° (subtract 127 on both sides)

The pairs of numbers below represent the price of different
quantities of books at 4 stores.
Which pair of numbers represents a proportional relationship?
o 4 books for $24,8 books for $40
o 5 books for $25, 6 books for $36
o 2 books for $14, 5 books for $35
o 3 books for $15, 7 books for $28

Answers

Answer:

Option C: 2 books for $14, 5 books for $35

Step-by-step explanation:

A proportional relationship between two quantities would always have a constant of proportionality. Thus,

Constant of proportionality, k = y/x

In this case,

x = quantity of books

y = price

Let's see which pair will have a constant of proportionality:

Option A: 4 books for $24,8 books for $40

24/4 = 6;

40/8 = 5.

No constant of proportionality.

Option B: 5 books for $25, 6 books for $36

25/5 = 5

36/6 = 6

No constant of proportionality.

Option C: 2 books for $14, 5 books for $35

14/2 = 7

35/5 = 7

Constant of proportionality, k = 7.

This pair represents a proportional relationship.

Option D: 3 books for $15, 7 books for $28

15/3 = 5

28/7 = 4

No constant of proportionality.

What is the slope of the line shown in the graph?

A. -3/2
B. -1/2
C. 3/2

Answers

Answer:

-3/2

Step-by-step explanation:

Answer:

The slope of the line shown is -3/2.

Step-by-step explanation:

You can find this by using the rise/run method between the two points.

Between the two points, the line falls 3 units down (this is the rise part) and goes 2 units to the right (this is the run part). Since the line falls 3 units down between the two points, this number would be -3, and since it runs to the right by two units, the slope can be identified as -3/2.

The area of a floor in square yards is one-ninth the area of the floor in square feet. Write an equation representing y, the area in square yards, to f, the area in square feet.
HELP ME

Answers

Answer:

y = f/9

Step-by-step explanation:

Area of a floor in square yards = y = f/9

Area of a floor in square feet = f

The number that represents the area of the floor in square feet is 9 times the number representing the area in square yards. This makes sense because the ratio of yard to feet is 1 : 3 and the ratio of square yard to square feet is the same ratio but squared so 1 : 9.

If y represents the area in square yards and f the area in square feet.

y = f/9

The speed of a fish before jumping out of the water can be represented by the equation s = 3h, where h

represents the height, in centimeters, the fish jumps out of the water and s represents the speed of the fish in

meters per second. If the fish is swimming at 15 meters per second before jumping out of the water, how high

can the fish jump?

Answers

Answer: The fish can jump 5m high.

Step-by-step explanation:

Given that

s = 3h

where

h  = the height(cm) the fish jumps out of the water

and s = speed of the fish(meters per second)  then

3 must have seconds as its unit.

Now, If the fish is swimming at 15 meters per second

Then the fish can jump =

s= 3h

15m/s =3h

h= 15m/s/3s

h= 5 meters

Determine whether the sequence is geometric. If so, find the common ratio. 3.0, 6.0, 12.0, 24.0

Answers

Answer:

The sequence is geometric and the common ratio is 2

Step-by-step explanation:

A sequence is geometric if each term  (after the first one) is equal to the term before it times some constant number, called the 'common ratio'.

Examples:  1, 2, 4, 8, 16, ... has a common ratio of 2 because 2*2 = 4, and 4*2 = 8, and so on.

                 Also, -->  4, 2, 1, 1/2, 1/4/ 1/8, ... has a common ratio of 1/2 because

4 * 1/2 =  the next term 2, and 2 * 1/2 = the next trem 1/4, and son on.

In this case, 3 * 2 = 6

                    6 * 2 = 12

                    12 * 2 = 24

The sequence is geometric and the common ratio is 2
