of the wheel, a distance of 117.75 feet. What is the radius, in feet, of
the ferris wheel? Use 3.14 for pi

Answer:

7

Step-by-step explanation:

Answer:

B) 18

Step-by-step explanation:

Perimeter = 2 + 2 + 1 + 2 + 1 + 2 + 1 + 4 + 1 + 2

= 4 + 3 + 3 + 5 + 3

= 7 + 8 + 3

= 10 + 8

= 18

The correct option is (B) 18

Answer:

18, option B

Step-by-step explanation:

the standard measure for speed is

miles per hour.

now we got as measurement

3 miles per 1/4 hour.

to give the standard speed or "unit rate" we assume that the bicyclist maintains the same speed for a whole hour.

and the question is : how many miles is he traveling then in that 1 hour ?

to answer this we have to check how often the actually measured unit of time fits into 1 hour.

1/4 hour fits 4 times into 1 hour.

and that factor applies now also to the miles to keep the value of the rate or ratio unchanged :

miles/time × a/a = miles×a/(time×a)

so that (time×a) = 1 hour

and so, he traveled 3×4 = 12 miles per hour.

Step-by-step explanation:

Answer: x = 20, y = -15

Step-by-step explanation:

Since we already know that [tex]y=-x+5[/tex], we can just substitute in that value of y into the other equation:

[tex]2x+3y=-5\\2x+3(-x+5)=-5\\2x-3x+15=-5\\-x=-5-15\\-x=-20\\x=20[/tex]

with the value of x, we can find the value of y:

[tex]y=-x+5=-20+5=-15[/tex]

The fraction of the sweaters that cost $50 or less is 50% is 1/2.

It is the middle value of the given set of numbers after arranging the given set of numbers in order.

We have,

From the box plot,

Median = $50

Now,

Median = $50

This means,

50% of the clothes are above $50 and 50% of the clothes are below $50.

Now,

The fraction of the sweaters that cost $50 or less is 50%.

So,

= 50/100

= 5/10

= 1/2

Thus,

The fraction of the sweaters that cost $50 or less is 50% is 1/2.

Answer:

False

Step-by-step explanation:

To be able to build a triangle, the sum of the lengths of any 2 sides must be greater than the length of the third side.

With lengths 9, 7, and 16, 9 + 7 = 16.

You would need 9 + 7 > 16.

Therefore, these sides cannot be used for a triangle.

Answer:

-88 and -87

Step-by-step explanation:

Since the two unknown integers are consecutive, one will be one more than the other. This means we can express them as x and x+1, so we only have one unknown in our equation. Since they add to -175, we can now write our equation:

x+(x+1) = -175

Take away brackets and combine like terms:

2x+1 = -175

Now we just need to isolate x which we can do by subtracting 1 from both sides and then dividing both sides by 2:

2x+1-1=-175-1

2x = -176

2x/2 = -176/2

x = -88

And our other number is -88+1 = -87

So our two numbers are -88 and -87 which are consecutive and add to 176:

-88+(-87) = -175

Step-by-step explanation:

First, we take $997 and subtract that by $349

$997 - $349 = $648

Answer:  x = 0.421053y+5.263158

Step-by-step explanation:

x = 0.421053y+5.263158

Answer:

x=0.042105y+10/19

Step-by-step explanation:

Let's solve for x.

19x−0.8y=10

Step 1: Add 0.8y to both sides.

19x−0.8y+0.8y=10+0.8y

19x=0.8y+10

Step 2: Divide both sides by 19.

19x/19=0.8y+10/19

x=0.042105y+10/19
