A team in science class placed a chalk mark on the side of a wheel and rolled the wheel in a straight line until the chalk mark
natita [175]
The amount of distance the wheel rolled is the circumference of that wheel. So we know the circumferenece of the wheel is 35cm; this is important because the formula for finding circumference is 2 \pi r = C. We can solve this for radius.

2 \pi r = 35

Divide by 2.
\pi r = 17.5

Divide by \pi
r = 5.57

So we now know the radius of the wheel is 5.57. We can then use this knowledge to find the area of the wheel. The formula for area is \pi r^2 = A

\pi 5.57^2 = A

Square 5.57.
\pi 31.02 = A

Multiply by \pi
97.47 = A

This means the answer is the last one in the list given.

A rental car company charges $22.15 per day to rent a car and $0.07 for every mile driven. Aubrey wants to rent a car, knowing t
Luda [366]

The number of days that Aubrey can drive to stay in her budget is 5 days.

<h3>Inequality signs and their meanings</h3>

> means greater than

< means less than

≥ means greater than or equal to  

≤ less than or equal to  

<h3>Equation that represents the question</h3>

Total amount that can be spent ≤ (cost to rent a car per day x number of days) + (cost per mile x total miles driven)

$130 ≤ ($22.15 x dd) + ($0.07 x 275)

<h3>Determination of the number of days that Aubrey can drive</h3>

130 ≤ ($22.15dd) + ($0.07 x 275)

130  ≤  $22.15dd + 19.25

130 - 19.25  ≤ $22.15dd

110.75  ≤ 22.15d

d  ≤ 110.75 / 22.15

d  ≤ 5

Each letter of L I T T R E L L is written on a card. The cards are placed in a basket. Find each probability if Elsa selects a c
masya89 [10]

Step-by-step explanation:

7. I believe it's independent because it makes sense and if it was dependent it wouldn't make senses.

8.For T you have 2 (Ts) so that give you a 2/8= 25% so you would basically make those Ts disappear and focus on 1 out of 6 and you'd get a 16.67% chance

9. 14.2857%

10. I don't understand ;-; am I suppose to multiply or see the chance if % it would get

I'm sorry;-;

Please help me with this
erica [24]

Answer:

a = 5

Step-by-step explanation:

If it's easier for you, you can replace n(a) with y and put a as x.

Now the equation is y = 7x + 4.

It asks you to put in 39 as y.

39 = 7x + 4.

To solve this, the goal is to isolate the variable on one side. The first step I see is to subtract the 4 from both sides.

35 = 7x

Now divide both sides by 7 and we're done!

5 = x
