Answer:

200

Step-by-step explanation:

Ella's name appears on the table 2/10 times, so we can multiply the denominator to make it 1000.

10x100 = 1000

If we multiply the denominator by 100, we must do the same to the numerator,

2x100=200

A pilot of a helicopter plans to release a bucket of water on a forest fire. The height y in feet of water t seconds after its r

frosja888 [35]

You’re gonna have to use the quadratic formula here and a bit of thinking. We know y is height, and once it touches the ground, it will be 0.

(-b +- sqrt b^2 - 4ac)/2a
2 +- sqrt(4 + 48(400))/-32
(2 +- 138.58)/-32
We don’t want a negative time because it’ll make no sense. So do subtraction

(2-138.58)/-32 = 4.27 seconds aka 4.3 seconds

Answer: 36 hotdogs

Step-by-step explanation: You need to find the least common multiple of 9 and 12.

You can check by multiplying 9 and 12 by consecutive whole numbers until you find a number that they match.

Example:

9*1= 9 , 9*2=18, 9*3= 27, 9*4=36, 9*5=45

12*1=12, 12*2=24, 12*3 =36

They both share 36.

Walt's Marina generated the following regression based on the number and cost of daily rentals of its boat slips to boat owners

Lana71 [14]

Answer:

The answer is "Option A and Option B"

Step-by-step explanation:

In question 1:

The fixed cost=2621.21

The unit variable cost=35.58

Calculating the total cost for 45 boat slips:

$=2621.21+(45 \times 35.58)\\\\=2621.21+(1601.1)\\\\=4222.31 \approx 4222$

In question 2:

It is the pure fixed costs that remain consistent in total regardless of dynamic loads. An overall cost B both for 1000 and 2000 unit is unchanged, therefore the Cost B is a fixed sum.
