What was the total cost?

Answer:

3 seconds

Step-by-step explanation:

Downwards positive

a = 32

s = 1000 - 760 = 240

s = ut + ½at²

240 = 32t + 16t²

t² + 2t - 15 = 0

t² + 5t - 3t - 15 = 0

t(t + 5) - 3(t + 5) = 0

(t - 3)(t + 5) = 0

t = 3, -5

By applying the equation of motion, we can determine that under the conditions specified in the question, it would take about 4.3 seconds for a pilot to fall from 1000 feet to 760 feet.

The question regards the time it takes for a pilot to fall a certain distance with a given initial velocity. The situation can be treated as a free fall, because while in the air the only force the pilot is subjected to (neglecting air resistance) is gravity. The key formula we need is the equation of motion d = vt + 0.5[tex]at^2[/tex],

where:

d is the distance fallen

v is the initial velocity

a is the acceleration due to gravity (9.8[tex]m/s^2[/tex])

t is the time

In this case, the distance d is 1000ft - 760ft = 240ft (73.152m), the initial velocity v is 32 ft/s (9.75m/s downwards).

Plugging these values into the equation, we get 73.152m = 9.75m/s *t + 0.5*(-9.8[tex]m/s^2[/tex])*[tex]t^2[/tex], which can be rearranged and solved to get t = 4.3s.

Step-by-step explanation:

Answer:

x = 1/8

Step-by-step explanation:

The first step is to make all of the denominators in the fractions the same. To do so, find what number multiplies by 4 to get to 8. This number is 2. Then, multiply that number to the numerator of the fraction you're going to change.

3/4 becomes 6/8.

The equation becomes 6/8 + x = 7/8.

Now, pay attention to the numerators. What number adds to 6 to get to 7? The answer is 1. Remember, the denominators must be the same, so the final answer is x = 1/8.

Answer:

A is proportional

B and C are NOT proportional

Step-by-step explanation:

First, simplify 588 and 60:

588 divided by 6

60 divided by 6

= 98

  10

Simplify them again by dividing them both by 2

= 49

   5

Let's look at A:

441 and 45

Simplify by dividing by 9

= 49

   5

It's pretty obvious that A is proportional because the simplified values are exactly the same.

Next, let's check B:

215  and 25

Simplify by dividing by 5

= 43

   5

Now that its simplified you can compare

43   is smaller than 49

5                               5

B is not proportional

Finally, let's check C:

649 and 110

Simplify by dividing by 11

= 51

  10

Make 51 and 49 have the same denominator so we can compare them

          10         5

51 can stay the same because 5 times 2 equals 10

10

49 times 2

5 times 2

=  98

    10

Now that the denominators are the same we can compare

51 is much smaller than 98

10                                     10

Therefore, C is also not proportional.

The velocity of Saige's spaceship is 9,809,809 km/s.

Given that Saige's spaceship traveled 588,588,588 kilometers in 60 seconds, we can calculate the velocity of the spaceship by dividing the distance traveled by the time taken. Velocity = Distance / Time. Velocity = 588,588,588 km / 60 s = 9,809,809 km/s. Therefore, the velocity of Saige's spaceship is 9,809,809 km/s.

Jamie has 9 possible combinations for breakfast based on her choices of 3 different foods and 3 different drinks.

The subject of the question is in the field of probability in mathematics. The question is asking for the total number of outcomes or combinations possible given Jamie's breakfast choices. Jamie can choose from 3 foods (cereal, eggs, muffin) and 3 drinks (coffee, orange juice, milk).

To find the total number of outcomes, you multiply the total number of options in each category. In this case, it would be 3 (food choices) multiplied by 3 (drink choices), which sets the total possible outcomes to be 9.

Therefore, Jamie has 9 possible combinations for her breakfast choice.

Answer:

x=4

Step-by-step explanation:

Answer:

Solve for the (number or thing that changes), so you need to (separate far from others)/get x by itself

-2x - 4 + 5x = 8 First I want to combine like terms (-2x and 5x)

-4 + 3x = 8 (Add 4 on both sides)

3x = 12 Then divide 3 into both sides to get x by itself

x = 4

Combine like terms (add the 5x to the -2x to get 3x). Move the -4 to the other side to get 3x= 12. Divide both sides by 3 to get x=4. Apply the addition property of (a state where all things are equal), Apply the division property of (a state where all things are equal) to divide both sides by 3, Finally, check the solution by substituting 4 into the original equation.

Given Information:  

Sample size = n = 40  

sample proportion = p = 35% = 0.35  

Required Information:

standard deviation of sample proportion = σ

Answer:  

standard deviation of sample proportion = σ = 0.075

Step-by-step explanation:  

Check if the condition np ≥  10 or n(1 - p) ≥ 10 is satisfied

np ≥ 10

40*0.35 ≥ 10

14 ≥ 10 satisfied

n(1 - p) ≥ 10

40(1 - 0.35) ≥ 10

26 ≥ 10 satisfied

Which means that distribution of sample proportion will have a mean closer to the population proportion.

The standard deviation for sample proportion is given by

[tex]\sigma = \sqrt{\frac{p(1-p)}{n}}[/tex]

[tex]\sigma = \sqrt{\frac{0.35(1-0.35)}{40}}[/tex]

[tex]\sigma = 0.075[/tex]

Therefore, the standard deviation for the sampling distribution of the sample proportions is 0.075.

The independent variable is; A: The number of secounds.

The dependent variable is; B) The number of feet the sub descends.

A dependent variable depends on another variable in a given data while an independent variable does not depend on any other variable.

We are told that the submarine is descending at a rate of 7 ft/s. Now, this means that for every second, he descends at a rate of 7ft. Thus, the more the number of seconds, the more the distance covered.

Thus, the number of feet depends on the time taken in seconds and such the independent variable is the the number of seconds while the dependent variable is the number of feet the sub descends.
