Answer 1

Answer:

  21.4  

Step-by-step explanation:

For this problem, you only need to know that the hypotenuse (x) is the longest side of the triangle. The only answer choice longer than 20 is ...

  x = 21.4

__

If you want to actually go through the numbers, you know that ...

  Cos = Adjacent/Hypotenuse

  cos(21°) = 20/x

  x = 20/cos(21°)

  x ≈ 21.4

A. 3,807 mph
B. 1,266 mph
C. 432 mph
D. 423 mph

Answers

Answer:

423 mph

Step-by-step explanation:

To find the answer, you have to divide 1,269 by 3 since we want to find how many miles the plane travels in one hour. Doing this, we end up with 423 which is the answer.

Answer: D. 423 mph

Find the slope of the line through (9, 4) and (0, 5).

Answers

Answer:

It's just y2-y1 over x2-x1

Step-by-step explanation:

so pick a coordinate and make it 1 and make the other one 2  and put in the numbers.

The slope of the line will be m = -1/9.

What is the general equation of a Straight line?The general equation of a straight line is -

        y = mx + c

        [m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

        [c] → is the y - intercept i.e. the point where the graph cuts the [y] axis

Other possible equations of line are -

(y - y₁) = m(x - x₁)                                {Point - slope form}(y - y₁) = (y₂ - y₁) × (x - x₁)/(x₂ - x₁)      {Two point - slope form}x/a + y/b = 1                                        {intercept form}x cos(β) + y sin(β) = L                        {Normal form}

We have a line through (9, 4) and (0, 5).

The slope of the line will be -

[m] = (4 - 5)/(9 - 0)

[m] = - 1/9

Therefore, the slope of the line will be m = -1/9.

A tree has a shadow length of approximately 9 feet. The distance from the tip of the tree to the tip of the shadow is bout 15 feet. How tall is the tree?

Please help!!!!!

Answers

this is a right triangle equation
so a^2 + b^2 = c^2
c^2 is the hypotenuse and the 15 feet

a^2 + 9^2 = 15^2
a^2 + 81 = 225
a^2 = 144

the square root of 144 is 12

the tree is 12 feet tall

Answer:

12

Step-by-step explanation:

if you draw the picture in your copybook you will see that there is a right triangle, we have the Pythagorean theorem i.e c=√a²+b²

15=√9²+x². the trees tall=X

15²=9²+x²

x²= 144

X= 12

Car A has an initial value of 30,000 and depreciates at a rate of 20% per year. Car B has an initial value of 20,000 and depreciates at a rate of 15% per year.Car B will become greater than the value of car A during the ninth,seventh,third, or fifth year

Answers

Answer:

The value of Car B will become greater than the value of car A during the fifth year.

Step-by-step explanation:

Note: See the attached excel file for calculation of beginning and ending values of Cars A and B.

In the attached excel file, the following are used:

Annual Depreciation expense of Car A = Initial value of Car A * Depreciates rate of Car A = 30,000 * 20% = 6,000

Annual Depreciation expense of Car B from Year 1 to Year 6 = Initial value of Car B * Depreciates rate of Car B = 20,000 * 15% = 3,000

Annual Depreciation expense of Car B in Year 7 =  Beginning value of Car B in Year 7 = 2,000

Conclusion

Since the 8,000 Beginning value of Car B in Year 5 is greater than the 6,000 Beginning value of Car A in Year 5, it therefore implies that the value Car B becomes greater than the value of car A during the fifth year.

It’s the 7th year

Let f(x) = 35

35 = (x-2)^5  +3

Subtract 3 from each side

35-3 = (x-2)^5  +3-3

32 = (x-2)^5

Take the fifth root of each side

32 ^ (1/5) =  (x-2)^5^ 1/5

2 = x-2

Add 2 to each side

Find the sum of the interior angle measures of a convex 15-gon (a fifteen-sided polygon).

Answers

Answer:

2340 degrees.

Step-by-step explanation:

The sum of the interior angle measures of any polygon can be calculated using the following expression ([tex]n[/tex] is the number of sides the polygon has):

[tex]180(n-2)[/tex]

For a 15-sided polygon, plug in 15 for n and simplify:

[tex]180(15-2)=180(13)[/tex]

Multiply to solve:

[tex]180(13)=2340[/tex]

For a 15-sided polygon, the sum of the interior angles must be 2340 degrees. You can go a step further and divide 2340 by 15 to figure out the individual measure of each interior angle (156 degrees).

The sum of the interior angles of a fifteen-sided polygon is 2340°.

What is the formula for interior angle of a regular polygon?

The formula for calculating the sum of interior angles is (n-2)×180° where is the number of sides. All the interior angles in a regular polygon are equal. The formula for calculating the size of an interior angle is: interior angle of a polygon = sum of interior angles ÷ number of sides.

Given that, a fifteen-sided polygon.

Now, the sum of the interior angle measures is

(15-2)×180°

= 13×180°

= 2340°

Therefore, the sum of the interior angle measures is 2340°.

what is the fraction of 2 1/4

Answers

Answer:

9/4

Step-by-step explanation:

2 1/4 = 9/4 From mixed fraction to an improper fraction: "the numerator of the improper fraction" = "denominator" xx "the whole number" + "the numerator of the mixed fraction" The denominator remains as it is. So 2 1/4 = (4 xx 2 + 1)/4 = 9/4

Answer:

9/4

Step-by-step explanation:

Multiply the denominator which is 4 by the whole number which is 2.

4 x 2 = 8

Next add the numerator to the 8.

8 + 1 = 9

The 9 is now the numerator and keep the original denominator.

A recent poll found that 76% of a random sample of 100 American movie goers thought the popcorn sold at the movie theatre was overpriced.

If the sample size was increased to 10,000 American movie-goers, what effect would this have on the estimated percentage of American movie-goers who

think the popcorn is overpriced?

Answers

Answer:

Step-by-step explanation:

Given that:

percentage of sample proportion = 76%

sample size = 100

Given that the sample proportion estimate is unbaised of the population proportion, then the percentage of all American movie-goers who think popcorn is overpriced is = 76%. Also, the mean of the sampling distribution appears to be independent of the sample size. Then, the estimate of the percentage will equally remain the same regardless it is even a sample of size 10000.
