Answer 1

Answer:

Step-by-step explanation:

∠BAC = 180° - 75° = 105°

The sum of the angles of a triangle is 180°.

(3x+2) + (10x-5) = 75

13x-3 =  75

x = 6

∠B = 3x+2 = 20°

∠BCF = 10x-5 = 55°

the jet stream is a wind current that flows across the US from west to east. Flying with the jet stream, an airplane flew 2700 miles in 4.5 hours. Against the same wind, the return trip took 6 hours. Find the speed of the plane in stil air and the speed of the jet stream.

Answers

Answer:

The speed of the plane in still air and the speed of the jet stream are 525 miles per hour and 75 miles per hour.

Step-by-step explanation:

From Mechanical Physics, we know that absolute velocity of the airplane ([tex]v_{A}[/tex]) is equal to sum of the absolute velocity of the jet steam [tex](v_{J})[/tex] and the relative velocity of the airplane with respect to jet stream (velocity of the airplane in still air) ([tex]v_{A/J}[/tex]). Al velocities are measured in miles per hour. Let suppose that both jet stream and airplanes travels at constant velocity. Now, we construct the following system of linear equations:

Flight with the jet stream

[tex]v_{J}+v_{A/J} = \frac{2700\,mi}{4.5\,h}[/tex]

[tex]v_{J}+v_{A/J} = 600\,\frac{mi}{h}[/tex] (1)

Flight against the jet stream

[tex]v_{J} -v_{A/J} = -\frac{2700\,mi}{6\,h}[/tex]

[tex]v_{J}-v_{A/J} = -450\,\frac{mi}{h}[/tex] (2)

The solution of this system of linear equations is:

[tex]v_{J} = 75\,\frac{mi}{h}[/tex], [tex]v_{A/J} = 525\,\frac{mi}{h}[/tex]

The speed of the plane in still air and the speed of the jet stream are 525 miles per hour and 75 miles per hour.

5. That cool CD you have been waiting to purchase has finally gone on sale over at Wal-Mart for 25% off the original price. You borrow your room-mates employee discount card and head on over to your local Wal-Mart. It turns out the employee discount entitles you to an additional 15% off the sale price of the CD. If the original price was $32.99, what was the total final price you paid for your cool new CD including the 7.5% sales tax

Answers

Answer: $22.61

Step-by-step explanation: A 25% discount means that instead of paying the full value, you will pay 25% less. So the total price you will pay for a CD of $32.99:

P₁ = 32.99 * (1 - 0.25)

P₁ = 32.99 * (0.75)

P₁ = 24.7425

However, you still have a discount of 15% over the price, so:

P₂ = 24.7425 * (1 - 0.15)

P₂ = 24.7425 * (0.85)

P₂ = 21.03

The sales tax is a value incorporated over the price after all the discounts:

P = 21.03 * (1 + 0.075)

P = 21.03 * (1.075)

P = 22.61

The total final price for the CD is $22.61.

The legs of a right triangle are in the ratio 3:4. If the hypotenuse is 10, what is the length of the longer leg?

Answers

Answer:

8

Step-by-step explanation:

ratios of legs = 3x and 4x

Pythagorean theorum:

A^2+B^2=C^2

3x^2+4x^2=10^2

9x^2+16x^2=100

25x^2=100  --> divide by 25

x^2=4 --> x=2

length of longer leg is 4x = 4 x 2 = 8

The length of the longer leg of the triangle is 8.

What is the Pythagorean theorem?

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.

Given that, the legs of the right triangle are in the ratio of 3:4.

Therefore, let the legs of the triangles be 3x and 4x.

Since the hypotenuse of the triangle is 10, using the Pythagorean theorem it follows:

10² = (3x)² + (4x)²

100 = 9x² + 16x²

100 = 25x²

x² = 4

x = 2

Therefore, the lengths of the legs are:

3(2) = 6, and

4(2) = 8

Hence, the length of the longer leg of the triangle is 8.

Find the volume of the solid generated by revolving the region bounded by the lines and curves about the x-axis. y = x, y =1, x = 0

Answers

Answer:

The volume is: [tex]V = \frac{\pi}{3}[/tex] cubic units

Step-by-step explanation:

Volume of a solid:

The volume of a solid, given by the function f(x), over an interval between a and b, is given by:

[tex]V = \pi \int_{a}^{b} (f(x))^2 dx[/tex]

y = x, y =1, x = 0

This means that the upper function is y = 1, and the lower function is y = x. So

[tex]f(x) = (1 - x)[/tex]

The lower limit of integration is x = 0.

The upper limit is y = x when y = 1, so x = 1.

Then

[tex]V = \pi \int_{a}^{b} (f(x))^2 dx[/tex]

[tex]V = \pi \int_{0}^{1} (1-x)^2 dx[/tex]

[tex]V = \pi \int_{0}^{1} (1-2x+x^2) dx[/tex]

[tex]V = \pi (x-x^2+\frac{x^3}{3})|_{0}^{1} dx[/tex]

[tex]V = \pi(1 - (1^2) + \frac{1^3}{3})[/tex]

[tex]V = \frac{\pi}{3}[/tex]

Step-by-step explanation:

Remove the parentheses first: 3/4 + (1/3 / 1/6) - (-1/2)

1/3 / 1/6 turns into 1/3 * 6

Reduce the numbers:

3/4 + (1/3 * 6) + 1/2

cross multiplication, 6 divided by 3 = 2.

So the new equation is 3/4 + 2 + 1/2

Then you calculate.

Answers

Answer:

The decrease in number of allergic reactions is of 0.3333%.

Step-by-step explanation:

Initial percentage:

Nine out of 1500, so the percentage is:

[tex]\frac{9*100}{1500} = \frac{900}{1500} = 0.6[/tex]

Initially: 0.6% of allergic reactions.

Final percentage:

Four out of 1500, so the percentage is:

[tex]\frac{4*100}{1500} = \frac{400}{1500} = 0.2667[/tex]

WIth the improved formula: 0.2667% of allergic reactions.

What is the percent decrease in number of allergic reactions?

0.6% - 0.2667% = 0.3333%

The decrease in number of allergic reactions is of 0.3333%.

Evapotranspiration is the sum of evaporation from plants.

Earth is surrounded by invisible gases that form a thin protective blanket that we call the atmosphere.

Water flows downhill because gravity is a form of potential energy – and the water, or anything that falls or rolls downward – flows in response to differences in potential energy (from high to low). ... Therefore, the potential energy that drives groundwater movement includes both pressure and gravity.

Precipitation: hail, rain, freezing rain, sleet and snow.

Condensation is the opposite of vaporization. Condensation occurs when a gas loses energy, slows in motion so that its cohesive force pulls the molecules close, but the molecules still have enough energy to break away from one connection only to connect with another molecule.

Alternatively evaporation of the liquid should leave a solid residue. ... Dissolving is a reversible process and the solute can be recovered from a solution by evaporation though it will not always be in the exactly the same form as at the start.

A publisher reports that 52% of their readers own a laptop. A marketing executive wants to test the claim that the percentage is actually different from the reported percentage. A random sample of 180 found that 46% of the readers owned a laptop. Find the value of the test statistic. Round your answer to two decimal places.

Answers

Answer:

The value of the test statistic is [tex]t = -1.61[/tex]

Step-by-step explanation:

Central Limit Theorem

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]

Our test statistic is:

[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the expected mean, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

A publisher reports that 52% of their readers own a laptop.

This means that [tex]\mu = 0.52[/tex]

Sample of 180:

Means that [tex]n = 180[/tex]

By the Central Limit Theorem:

[tex]\frac{\sigma}{\sqrt{n}} = s = \sqrt{\frac{0.52*0.48}{180}} = 0.0372[/tex]

A random sample of 180 found that 46% of the readers owned a laptop.

This means that [tex]X = 0.46[/tex]

Find the value of the test statistic.

[tex]t = \frac{X - \mu}{s}[/tex]

[tex]t = \frac{0.46 - 0.52}{0.0372}[/tex]

[tex]t = -1.61[/tex]

The value of the test statistic is [tex]t = -1.61[/tex]

what is the remainder when 849,400 is divided by 216​

Answers

The anserws is 88 so your welcome

Answer:

The remainder is 88

Step-by-step explanation:

The Remainder of a Division

We have to find the remainder when we divide 849,400 by 216.

It could be found by doing the long division, but we'll do it with a calculator.

Entering the division in the calculator we get:

849,400/216=3,932.4074...

We take the whole part of the quotient (3,932) and multiply it by the divisor:

3,932*216=849,312

The remainder is obtained by subtracting 849,400-849,312=88

Answers

Answer:

A) 14.3606 ft

B) 2.8112 seconds

Step-by-step explanation:

A) At maximum height which is its peak, the velocity will be zero.

Now, we are given height modeled by;

h(t) = 4.98t² - 14t + 20

v(t) = dh/dt = 9.96t - 14.

At max height which is v(t) = 0, we have;

9.96t - 14 = 0

9.96t = 14

t = 14/9.96

t = 1.4056 s

Thus, height at this time is;

h(1.4056) = 4.98(1.4056)² - 14(1.4056) + 20

h(1.4056) = 14.3606 ft

B) time of flight = 2 × time to get to peak = 2 × 1.4056 = 2.8112 seconds.
