Answer:

√216 meters

Step-by-step explanation:

» Concepts

The Pythagorean theorem states that in a right triangle, the sum of the squares of the legs is equal to the length of the hypotenuse squared. It's represented as an equation of a² + b² = c², where a & b are the legs, and c is the hypotenuse

» Application

To find the length of the other leg, we have to plug in the values of b and c into the equation. B would be 15 meters, and c would 21 meters.

» Solution

Step 1: Simplify both sides of the equation.

Step 2: Subtract 225 from both sides.

Step 3: Take square root of both sides.

Therefore, the length of the other leg is √216 meters.

Answer:

Parallel lines have the same slope, so in y = mx +b, m would have the same value for both.

In perpendicular lines, the value of the m is inversed. Because the m is over an invisible one in this case, m/1(x) becomes -1/m(x), making the equation y = 1/m(x) + b

Point-slope form is (y - y1) = m (x - x1), meaning that the first term of y subtracted from the zeroth term of y is equivalent to m multiplied by the value of the first term of x from the zeroth term of x

Answer:

(x-4)^2 + (y-5)^2 = 20

Step-by-step explanation:

Rearrange the line equation of 5x - 2y + 6 = 0

So y = 5/2x +3

The y-intercept of the line equation is 3 as when x=0, y=3.

We know the Circle has the formula [tex](x-4)^2 + (y-5)^2 = ?^2[/tex] from the question but with the intercept, we can find the entire equation as the y-intercept is (0,3) so we can substitute it into the equation to find the full equations so:

[tex](0-4)^2 + (3-5)^2 = ?^2[/tex]

This simplifies to:

[tex](-4)^2 +(-2)^2[/tex] = [tex]?^2[/tex]

16 + 4 = 20 = [tex]?^2[/tex]

The answer is 20 so the equation of the circle is [tex](x-4)^2 + (y-5)^2 = 20[/tex]

Step-by-step explanation:

The United States has a complex government system. One important tenet of this system is democracy, in which the ultimate power rests with the people. In the case of the United States, that power is exercised indirectly, through elected representatives. Although the U.S. has been a strong proponent of democracy, it did not invent democracy. The Greeks are often credited with pioneering a democratic government that went on to influence the structure of the United States. Read this article that describes how elements of ancient Greek democracy heavily influenced the figures that designed the United States government.

Answer:

6.08

Step-by-step explanation:

For four brushes its 16 and for two rollers and trays its 16. Add that with the tax and you’ll get 33.92. Subtract 40 with the overall cost to get 6.08

Answer:

$6.08

Step-by-step explanation:

To find the change you must add together the cost of all the items and the tax. then subtract that by 40 dollars

So . .

Painbrushes cost $4.00

Rollers cost $8.00

Add them

Then Subtract that from $40.00

So. .

= $6.08

Answer:

A. $2.78Step-by-step explanation:You would multiply the cost per pound, $2.14, by the amount of pounds bought, 1.3. Then round to the nearest hundredth.2.14 x 1.3 = 2.7822.782 rounded to the nearest hundredth is $2.78

Step-by-step explanation:

If he makes his trade on the day with the least favorable exchange rate, the amount received is ins 38.35

From the complete question, we have the following parameters:

£1= 0.47 --- least favorable rate

Given that the uses a charge of 8%, the amount received when he converts  £88.65 is calculated using:

Amount = Rate * Amount * (1 - 8%)

So, we have:

Amount = 0.47 * 88.65 * (1 - 8%)

Evaluate the product

Amount = 38.33

The closest amount to 38.33 is 38.35.

Hence, the amount received is ins 38.35

In Total there are 43 jelly beans, which means that will be our denomintor.(sorry if i spelled that wrong)

12/43 are red      17/43 are white        14/43 are black = 43/43

27.9% of 43       +   39.5% of 43       +   32.6% are black = 100%

There is the highest chance that the jelly beans chosen will be white, with black following. 2 white & 3 black would be 5/43 which is 11.6% of the jelly beans in total. Of this chance there is about a 25% chance that white will be chose & 27-30% chance that black will be chosen.

Answer:

  7.07 years

Step-by-step explanation:

The standard deviation of a population is easily calculated by a spreadsheet or calculator. Care must be taken to use the formula for population standard deviation, rather than the formula that assumes the values are a sample.

__

The attached calculator shows the standard deviation is about 7.07 years.

_____

Additional comment

The population standard deviation is the square root of the variance. The variance is the mean of the squares of the values, less the square of the mean of the values. The second attachment shows the calculation done this way.

The units of standard deviation are the same as the units of the members of the population. Here, that is "years."

The statement 'if you are balancing an object on its center of mass, there must be equal amounts of mass on both sides of the center of mass" is false.

A place at which the entire mass of a body or all the masses of a system of particles appears to be concentrated is defined as the center of mass of a body or system of particles.

We have statement:

If you are balancing an object on its center of mass, there must be equal amounts of mass on both sides of the center of mass.

As we know, center of a mass is an object balance point it doesn't need to have equal amounts of mass on both sides of the center of mass.

Thus, the statement 'if you are balancing an object on its center of mass, there must be equal amounts of mass on both sides of the center of mass" is false.

Answer:

1/3 or 1:3

Step-by-step explanation:

since there is a 10/30 chance

to simplify divide by 2

10/30 ÷ 2/2 = 5/15

then divide by 5

5/15 ÷ 5/5 = 1/3

your answer is 1/3

another simple way to simplify

since there is a zero (0) in both the ones (1s) spot on both the numerator and denominator in 10/30, you may just cross out both zeros (0s) to simplify the value

10/30 simplified/taken away 0s = 1/3

Answer:

EH = 120 degrees

Step-by-step explanation:

angles in a circle add up to 360 degrees

arc EF + arc FG + arc GH + arch EH = 360

95 + 90 + 55 + EH = 360

240 + EH = 360

subtract 240 from both sides to isolate EH

EH = 120 degrees

Answer:

Step-by-step explanation:

We need to determine how many ways we can choose 4 questions out of 7 to make the quizzes.

We do this by using the formula [tex]\displaystyle nCr=\frac{n!}{r!(n-r)!}[/tex] which describes the number of ways we can choose [tex]r[/tex] objects given [tex]n[/tex] possible choices. So, if [tex]n=7[/tex] and [tex]r=4[/tex], then:

[tex]_4C_7=\frac{7!}{4!(7-4)!}\\\\_4C_7=\frac{7*6*5*4!}{4!*3!}\\\\_4C_7=\frac{210}{6}\\\\_4C_7=35[/tex]

The events are mutually exclusive and the probability of drawing a card from a standard deck and choosing a 7 or a 9 is 2/13

The given parameters are:

Standard deck = 52

n(7) = n(9) = 4

The probability of choosing a 7 or a 9 is calculated as:

P(7 or 9) = P(7) + P(9)

So, we have:

P(7 or 9) = 4/52 + 4/52

Evaluate

P(7 or 9) = 8/52

Simplify

P(7 or 9) = 2/13

Hence, the probability of drawing a card from a standard deck and choosing a 7 or a 9 is 2/13
