The veloctiy of sound in air is given by the equation v=20 times the square root of 273+t where v is the velocity in meters per second and t is the temperature in degrees Celcius. Find the temperature when the velocity of sound in air is 369 meters per second. Round to the nearest degree.

Answers

so we just need to plug in our values and solve
[tex]v = 20 \sqrt{273 + t} [/tex]
we are given v is 369 so we have
[tex]369 = 20 \sqrt{273 + x} [/tex]
now we solve for x.
divide both sides by 20
square both sides
subtract 273 from both sides
[tex]369 = 20 \sqrt{273 + x} \\ 18.45 = \sqrt{273 + x} \\ 340.40 = 273 + x \\ x = 67.4[/tex]
so a temp of about 67 degrees C

Answer:

The velocity of sound in air is 369 meters per second at 67 degrees Celcius.

Step-by-step explanation:

The veloctiy of sound in air is given by the equation

[tex]v=20\sqrt{273+t}[/tex]

where v is the velocity in meters per second and t is the temperature in degrees Celcius.

We need find the temperature when the velocity of sound in air is 369 meters per second.

Substitute v=369 in the give equation.

[tex]369=20\sqrt{273+t}[/tex]

Divide both sides by 20.

[tex]\frac{369}{20}=\sqrt{273+t}[/tex]

[tex]18.45=\sqrt{273+t}[/tex]

Taking square both the sides.

[tex](18.45)^2=273+t[/tex]

[tex]340.4025=273+t[/tex]

Subtract 273 from both the sides.

[tex]340.4025-273=t[/tex]

[tex]67.4025=t[/tex]

[tex]t\approx 67[/tex]

Therefore the velocity of sound in air is 369 meters per second at 67 degrees Celcius.

A diagonal shortcut across a rectangular lot is 130 feet long. The lot is 50 feet long. What is the other dimension of the lot

Answers

We use the pithagorean formula: x^2 = 130^2 - 50^2 = 16900 -2500 = 14400;
then, x = [tex] \sqrt{14400} [/tex] = 120 feet has the other dimension of the lot.

Final answer:

The other dimension of the rectangular lot is 120 feet.

Explanation:

In a rectangular lot, the diagonal forms a right triangle with the two sides of the rectangle. We can use the Pythagorean theorem to find the length of the other dimension of the lot.

Let's assume that the other dimension of the lot is x feet. The diagonal, which is 130 feet, is the hypotenuse of the right triangle. The two sides of the rectangle are 50 feet and x feet.

Using the Pythagorean theorem, we have:

x2 + 502 = 1302

x2 + 2500 = 16900

x2 = 14400

x = √14400 = 120

Therefore, the other dimension of the lot is 120 feet.

find the value of sin2a, if tana=-12/5 in the fourth quadrant

Answers

[tex]\tan a=-\dfrac{12}5[/tex]

Recall the following identities:

[tex]1+\tan^2a=\sec^2a=\dfrac1{\cos^2a}[/tex]
[tex]\cos^2a=\dfrac{1+\cos2a}a[/tex]

from which we get

[tex]1+\left(-\dfrac{12}5\right)^2=\dfrac1{\cos^2a}[/tex]
[tex]\implies\cos^2a=\dfrac{25}{169}[/tex]

Since [tex]a[/tex] is in the fourth quadrant [tex]\left(\dfrac{3\pi}2<a<2\pi\right)[/tex] we know that [tex]\cos a[/tex] should be positive, so when we take the square root here, we should take the positive root.

[tex]\implies\cos a=\sqrt{\dfrac{25}{169}}=\dfrac5{13}[/tex]

Now recall that

[tex]\cos^2a+\sin^2a=1[/tex]

and since [tex]a[/tex] is in the fourth quadrant, we expect [tex]\sin a[/tex] to be negative. So,

[tex]\sin^2a=1-\cos^2a=\dfrac{144}{169}\implies\sin a=-\sqrt{\dfrac{144}{169}}=-\dfrac{12}{13}[/tex]

One final identity:

[tex]\sin2a=2\sin a\cos a[/tex]

from which we get

[tex]\sin2a=2\cdot\left(-\dfrac{12}{13}\right)\cdot\dfrac5{13}=-\dfrac{120}{169}[/tex]

Find the final cost to the employer.
Original price: $129.00
Employee discount: 20%
Sale discount: 30%
Sales tax: 5%
a.$75.85
b.$70.95
c.$68.63
d.$67.72
e.$61.28

Answers

The correct answer is A) $75.85.

A discount of 20% means that the cost is 80% of the original. 80%=80/100=0.8

0.8(129) = 103.20

A discount of 30% means that the cost is 70% of the amount before discount. 70%=70/100=0.7
0.7(103.20) = 72.24

A sales tax of 5% means that it is 105% of the amount pre-tax. 105%=105/100=1.05
1.05(72.24) ≈ 75.85

Brett colors 25% of the total shapes on his paper he colors 6 shapes enter the total number of shapes on bretts paper

24 because if 6 is 25%, 25% is 1/4 of 100 so you have to multiply 25 and 6 by 4 to get 24=100%

Based on the information given the total number of shapes on bretts paper is 24 shapes.

Using this formula

Total number of shapes=Number of shapes/Percentage of total sales

Where:

Number of shapes=6

Percentage of total sales=25% or .25

Let plug in the formula

Total number of shapes=6/.25

Total number of shapes=24 shapes

Of the 34 cars in a parking lot, 20 are green, 8 are gold, and the rest are black. What are the odds against the next car leaving the lot being black?

Answers

The odds against the next car leaving the parking lot being black are calculated by finding the number of black cars (6) and using the formula (Total cars - Black cars) : Black cars, which results in odds of 14:3.

To answer the question regarding the odds against the next car leaving the parking lot being black, we need to calculate the number of black cars and then the odds.

There are a total of 34 cars in the lot, with 20 green and 8 gold, so the rest are black.

To find the number of black cars, subtract the number of green and gold cars from the total:
34 (total cars) - 20 (green cars) - 8 (gold cars) = 6 (black cars).

The odds in favor of an event are the ratio of the probability of the event happening to the probability of it not happening. Therefore, the odds against an event are just the opposite -- the ratio of the probability of the event not happening to the probability of it happening.

To calculate the odds against picking a black car, we use this ratio:
Odds against a black car = (Total cars - Black cars) : Black cars
Odds against a black car = (34 - 6) : 6
Odds against a black car = 28 : 6
Odds against a black car = 14 : 3.

So, the odds against the next car leaving the lot being black are 14:3.

Part 1:
The parimeter of the square by definition is given by:
P = 4L
Substituting values:
P = 4 (2x + 4)
Rewriting we have:
P = 8x + 16

Part 2:
For x = 5 we have:
P = 8 (5) + 16
P = 40 + 16
P = 56

Part 3:
The area of the square is:
A = L ^ 2
Substituting values:
A = (2x + 4) ^ 2
For x = 3 we have:
A = (2 (3) + 4) ^ 2
A = (6 + 4) ^ 2
A = (10) ^ 2
A = 100

figure lmno is a rectangle. The slope of LM is -1/2. What are the slopes of MN and OL?

Answers

The slope would be 2 because the sides would have to be perpendicular to each other since it is a rectangle and to get the perpendicular slope, you get the opposite reciprocal of -1/2 which is 2. (drawing it out helps)

Answer:

The slopes of these other two segments would be 2.

Step-by-step explanation:

In order to find these slopes, you need to know that rectangles have right angles. Given this fact, we know these segments are perpendicular to the given segment. This means that we take the current slope (-1/2), we flip it, (-2) and negate it (2) to get the new slope.

hope it helps

There are 10 possible outcomes in the sample space when tossing a coin and spinning a spinner with 5 equal sections.

When tossing a coin and spinning a spinner with 5 equal sections, the total number of outcomes in the sample space can be calculated by multiplying the number of outcomes for each event.

For the coin toss, there are 2 possible outcomes: heads (H) or tails (T).

For spinning the spinner, there are 5 possible outcomes: each of the 5 sections.

So, the total number of outcomes in the sample space is the product of these two numbers:2×5=10.
