Answer:

The numbers that 4320 is divisible by are 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 27, 30, 32, 36, 40, 45, 48, 54, 60, 72, 80, 90, 96, 108, 120, 135, 144, 160, 180, 216, 240, 270, 288, 360, 432, 480, 540, 720, 864, 1080, 1440, 2160, and 4320.

Step-by-step explanation:

Because if u multiply 1 and 4320, you get 4320

then if you multiply 2 and 2160, you get 4320

and just keep doing that with all of the other numbers

Answer:

0. See explanation below.

Step-by-step explanation:

Grayson is playing a game in which the objective is to obtain a zero, by adding together the points scored in each round.

For rounds 1 to 4,

4 + 7 + 1 + -12  =  12 - 12  = 0

The summation of points in the first four rounds already results to a zero.

Let us see if the addition of any of the three options for round 5 will still result in a zero!

0 + -24  =  -24

0 + -11    =  -11

0 +  12    =  12

So all the options here are wrong. The only option that would have been correct is 0.

Since   4 + 7 + 1 + -12 + 0  = 0

Maybe the complete question has 0 as the fourth option. Use that.

Answer:

Number of days= 12.5

Step-by-step explanation:

Giving the following information:

A bake sale committee wants to raise $175 for a donation to a local charity. They set aside $14 of their profit at the end of each day.

To calculate the number of days required to raise $175, we need to use the following formula:

Number of days= total amount / profit per day

Number of days= 175/14

Number of days= 12.5

Answer:

2.08333333333

Step-by-step explanation:

Answer: Each card costs $2.08

Step-by-step explanation: This is because you need to divide the cost for 12 cards by 12. 25/12 is 2.08333333... so you can round that to $2.08.

Answer: £1517.04

Step-by-step explanation:

The fuel expenses for the vans will be calculated as:

Vans:

Since the average distance travelled per day is 198km and the average distance travelled per litre is 9km, the van would use:

= 198/9

= 22 litres

Since there are 8 vans, they'll use:

= 22 × 8 = 176 liters

Trucks:

Since the average distance travelled per day is 620km and the average distance travelled per litre is 6.2km, the truck would use:

= 620/6.2

= 100

Since there are 10 trucks, they'll use:

= 100 × 10 = 1000 liters

The amount of liters for both the van and the truck will be:

= 176 liters + 1000 liters

= 1176 liters

The fuel cost will then be:

= 1176 × 1£1.29

= £1517.04

Answer:

The answer to the first question is 7.15

The answer to the second question is 1.73

Answer:

7.15; 1.73

Step-by-step explanation:

6.2 is the same as 6.20, so:

  6.20

+ 0.95

= 7.15

0.8 is the same as 0.80, so:

 2.53

- 0.80

= 1.73

Step-by-step explanation:

Step 1: Define

f(x) = -x - 4

f(4) is x = 4

Step 2: Evaluate

Answer:

The correct option is c. 23.53%.

Step-by-step explanation:

The annual percentage yield (APY) can be calculated using the following formula:

APY = (1 + r / n)^n - 1 .............................. (1)

Where;

APY =  Annual percentage yield = ?

r = Annual percentage rate = 22.29%, or 0.2229

n = Number of compounding period per year = Semiannually = 2

Substituting the values into equation (1), we have:

APY = (1 + 0.2229 / 2)^2 - 1

APY = 0.2353211025, or 23.53211025%

Rounding to 2 decimal places, we have:

APY = 23.53%

Therefore, the correct option is c. 23.53%.

Answer: 8a+8b−12

Step-by-step explanation: 8a+5b−3+3(b−3)

=8a+5b+−3+(3)(b)+(3)(−3)

=8a+5b+−3+3b+−9

=(8a)+(5b+3b)+(−3+−9)

=8a+8b+−12

Answer:

mean 16.75

median 15.5

mode 13

range 16

Answer:

25.5 is the median, 22 is the mode, 24.7 is the mean and 34 is the range

Step-by-step explanation:

mean is the average, you get this by adding up all the numbers and then dividing the total by the amount of numbers there are.

the median is the number with the middle value, in this case there were 2 medians because the was an even number of numbers so you average the medians

mode is the number the occurs the most out of the whole set. For example in this case all the numbers occurred twice except 22 which occured 3 times

Last is the range which takes the highest number and subtracts it by the lowest number. It's just that simple!

Answer: The height of the tree is 21 feet.

Step-by-step explanation:

Here we can assume that the angle at which the sun impacts the photographer and the tree to be the same angle.

Then we can think in both cases as triangles rectangles, where the height is a cathetus, and the shadow is the other cathetus.

Then we will have a relationship like:

Tg(angle) = shadow/height

height = shadow/Tg(angle)

Now, because for both triangles we have the same angle, then Tg(angle) will be the same number for both cases, and we can just think of it as constant K

Tg(angle) = K

Then we have the equation:

Height = Shadow/K

We know that the photographer is 6ft tall, and his shadow is 2 ft long, we can replace those two things in the above equation and find the value of k:

6ft = 2ft/K

K = 2ft/6ft = (1/3)

Now we know that the shadow of the tree is 7ft long, then the height will be:

height = 7ft/(1/3) = 7ft*3 = 21ft

The tree is 21 ft tall.
