Answer:

b) $475

Step-by-step explanation:

if it has a diameter of 22 feet, that means it has a radius of 11 feet

the formula of the area of a circle is πr². so square the radius and you will get 121, multiply that by π and you get 380

Now we know the area is 380 square feet, so multiply that by $1.25 and the answer is $475

The distance around the oval track would be 556.9 m which is the sum of the perimeter of the square and the circumference of the semi-circles.

The Circumference of a circle is defined as the product of the diameter of the circle and pi.

C = πd

where 'd' is the diameter of the circle

We have to determine the distance around the track

The required distance is equal to the sum of the perimeter of the square and the circumference of the semi-circles.

A middle school has an oval track with the dimensions shown.

Here the length of a side of the square = 78 m

And the diameter of the circle = 78 m

the distance around the track = perimeter of  square + circumference of the circle

the distance around the track = 4 × 78 + π × 78 / 2 + π × 78 / 2

the distance around the track = 4 × 78 + π × 78

the distance around the track = (4 + π) × 78

the distance around the track = (4 + 3.14) × 78

the distance around the track = 7.14 × 78

the distance around the track = 556.9 m

Therefore, the distance around the oval track would be 556.9 m.

Answer:

the answer is B

Step-by-step explanation:

hope this helps you!

Answer:

B

Step-by-step explanation:

You see that the question mentions MPH. An hour is 60 minutes, so you would look at the 60 minutes on the base of the graph. If you go directly up to where the diagonal (dark) line perfectly crosses a point of the grid (that's any corner of any square on this grid) and look directly to the left (which represents the MPH) you see the number 3. If you go even higher, you see 6 MPH.

The 3 miles at 60 minutes represents 3 MPH, which is Tanisha's speed.

The 6 miles at 60 represents 6 MPH, which must be Albert's speed.

Since 6 is two times bigger than 3, the correct answer is B) Albert is running two times faster than Tanisha is walking.

Answer:

$700

Step-by-step explanation:

25% = 1/4

the sales would be 100% or 4/4

So if commission rate is 1/4, to find the sales we multiply this by 4:

$175*4= $700

The sales would amount to $700

Hope this helps :)

Step 2: Evaluate

Follow Order of Operations.

Answer:

43

Step-by-step explanation:

Assuming you meant "evaluate x+3 squared          - 6    when x = 4, we get:

(x + 3)^2 - 6

Substituting 4 for x, we get 7^2 - 6, or 43.

Answer: 9:00 PM

Step-by-step explanation:

every 24 hours it will 4:00 PM again - so we do . . .  245 ÷ 24 = 10 days and 5 hours.  

so in 245 hours it will be 9PM

Answer:

Part A:  -1/4

Part B:  2/5

Step-by-step explanation:

The values of a function are the true values of the function.

The value of x is 5

The functions are given as:

When x = 2 to 6, we have:

When x = 2 to 6, we have:

By comparison:

So, we have:

Hence, the value of x is 5

2. 277

Step-by-step explanation:

I'm not too sure which answer you're looking for but I'll try to answer all of them :).

First of all, we can consider them in percentage form first.

If the first sale price is marked down by 30%, it is now 70%.

For the second, the price is marked down by 20% first, so 80%.

And then another 10% on top of the 80%. 10% of 80 is 8, so the second one is marked down 80-8, or 72%.

As we can clearly see, 72% is greater than 70% so the first deal( 30% off ) would give you a cheaper price

Now we move on to the actual prices.

First one is 70% of the original price, 70% of $385 is $269.5.

Second one is 72% of original price, 72% of $385 is $277.2

Don't forget to round to the nearest dollar!

Answer:

I don’t know the answer but I can try to help.

Step-by-step explanation:

The slope is the measurement of the steepness of a line, so all you would have to do is find the steepness of the line on that graph.

Answer:

" all numbers less than -27 "

Step-by-step explanation:

The instructions for this problem most likely go like this:  "solve the following identity."  In other words, find an inequality for n.

Start by multiplying both sides of the given inequality by 3, to eliminate the fraction 1/3:

n < -27

The solution:  " all numbers less than -27 "

Answer:

Minus 4 from 16 = 12

12 is 3/10ths of the number. So, divide it by three. This is 4 and then you do 4*10 = 40

I think this is correct

Answer:

C

Step-by-step explanation:

To calculate the left side of the ratio, our calculator multiplies the right side by 14 and then divides the product by 4. To calculate the right side of the ratio, our calculator multiplies the left side by 4 and then divides the product by 14. Answers are rounded to two decimals if necessary.

Answer:

This problem is easy but I'll demonstrate an approach for simplifying these kind of problems that can be applied to problems of higher complexity.

Key: Notice that you can write AH as 10A + H and HEE as 100H + 10E+E, and thus

AH +A = HEE

10A + H + A = 100H + 10E +E

11A + H = 100H + 11E

11A = 99H + 11E

A = 9H + E

As H can not be 0 (it is the leading digit in HEE), A must be at least and therefore exactly 9 and the problem solves itself from there on.

Step-by-step explanation:

Answer:

On first visit, weight =550 g

Weight gained on second visit= 350 g

Weight gained on third visit= 300 g

Present weight=550+350+300= 1200

Weight gained=1200-550=650

Percentage of weight increased

-------->650/550 × 100 = 118.18\%

So the kitten gained 118% weigh
