Doughnuts cost $3.45 for a dozen at Store A, and cost $2.40 for 8

Mathematics

Answer:

store A is cheaper

Step-by-step explanation:

All right. If you divide Store A's numbers like so,

3.45 / 12, you'd get about 0.28, which is the average cost per one donut at store A.

For store B, if you divided,

2.40/8, you'd get 0.30, which is the average cost per one donut at store B, which means that store A is cheaper!

Marlo uses 252 lb of gravel to cover a garden plot of 36 ft2. clear check how many pounds of gravel does it take to cover one sq
timama [110]

7 lb will cover an area of 1 square foot, while 315 lb will cover an area of 45 square feet.

From given question,

252 lb = 36 ft²             ..........(1)

The number of pound for an area of 1 square foot is calculated as follows:

x = 1 ft²                       .......(2)

The area and the amount of gravel are illustrations of proportions.

From (1) and (2) we get an equation,

⇒ x × 36 = 252 × 1

⇒ x = 252/36

⇒ x = 7 lb

We need to find the area that could be covered with 315 lb of gravel

The area to be covered with 315 lb gravel is calculated as follows:

315 lb = y               ............(3)

From (1) and (3) we get an equation,

⇒ y × 252 = 36 × 315

⇒ y = 45 ft²

Therefore, 7 lb will cover an area of 1 square foot, while 315 lb will cover an area of 45 square feet.

What is the sum of 9c+(8+3c)?
mixas84 [53]
<span>9c+(8+3c)      
9c+8+3c     (collect like terms)

9c+3c+8
12c+8

12c+8 is the answer.
im not sure if your teacher also wants the answer to be in simplest form so im going to do that below as well:

12c+8      (4*3=12 and 4*2=8. you can take out a 4 from those 2 numbers)

4(3c+2) (this is the simplest form of </span>9c+(8+3c)<span>)

The 1992 world speed record for a bicycle (human-powered vehicle) was set by Chris Huber. His time through the measured 200 m st
Reil [10]

Answer:

a) 30.726m/s and b) 5.5549s

Step-by-step explanation:

a.) What was Chris Huber’s speed in meters per second(m/s)?

Given the distance and time, the formula to obtain the speed is

v=\frac{d}{t}.

Applying this to our problem we have that

v=\frac{200m}{6.509s}= 30.726m/s.

So, Chris Huber’s speed in meters per second(m/s) was 30.726m/s.

b) What was Whittingham’s time through the 200 m?

In a) we stated that v=\frac{d}{t}. This formula implies that

  1. t=\frac{d}{v}.

First, observer that 19\frac{km}{h} =19,000\frac{m}{h}=\frac{19,000}{3,600}m/s= 5.2777m/s.

Then, Sam Whittingham speed was equal to Chris Huber’s speed plus 5.2777 m/s. So, v=30.726\frac{m}{s} +5.2777\frac{m}{s}= 36.003 m/s.

Then, applying 1) we have that

t=\frac{200m}{36.003m/s}=5.5549s.

So, Sam Whittingham’s time through the 200 m was 5.5549s.
