What is the length of the unknown leg of the right​ triangle?

Answer:

Step-by-step explanation:

Givens

Time 1 = 11.74

Time 2 = 11.26

Time 3 = 12.12           Add

Solution

11.74 + 11.26 + 12.12 =

Total Time = 35.12

35.12 miles is the total number of minutes that it took krissy to run these three miles.

What is a simple definition of time?

The measured or measurable period during which an action, process, or condition exists or continues : duration. b : a nonspatial continuum that is measured in terms of events which succeed one another from past through present to future.

Krissy ran three miles one morning she ran the first mile in time 1 = 11.74

Krissy ran three miles one morning she ran the first mile in time 2 = 11.26

Krissy ran three miles one morning she ran the first mile in time 3 = 12.12          

To get total time , we have to add all the time 1,2,3

Total time = Time1 + Time2 + Time3

                  = 11.74 + 11.26 + 12.12

Total Time =  35.12 miles

Answer:

\(x=360\)

Step-by-step explanation:

The inscribed angles theorem states that when given a circle, with an angle that has its vertex at the center of the circle, the measure of the angle is congruent to the measure of the arc surrounding it. One can apply this knowledge here by stating the following,

\(m<MON = MN\\\)

Substitute,

\(x=2\pi\)

However, this answer is in radians, it is the literal measurement. One must convert into degrees so that the answer fits the format of the question. The conversion rate to switch between radians and degrees is the following,

\(degree=\frac{\pi}{180}radians\)

Substitute,

\(degree=\frac{180}{\pi}(x)\\\\degree=\frac{180}{\pi}(2\pi)\\\)

Simplify,

\(degree=\frac{180*(2\pi)}{\pi}\\degree=360\)

Answer:

x = 45°

Step-by-step explanation:

Given arc length = 2π cm

         Radius, r = 8 cm

      \(Arc \ Length = 2 \pi r (\frac{x}{360})\)

             \(2 \pi = 2 \pi \times 8 \frac{ x}{360}\\\\\frac{2 \pi}{16 \pi} = \frac{x }{ 360}\\\\\frac{1}{8} = \frac{x}{360}\\\\\frac{360}{8} = x\\\\x = 45^\circ\)

The region is made up of

• a right triangle with short leg 10 m and hypotenuse 26 m

• a parallelogram with sides 40 m and 26 m (the 26-m side corresponds to the aforementioned hypotenuse)

• another triangle with two known legs of length 20 m and 26 m

Find the height of the right triangle using the Pythagorean theorem. If the height is h, then

(10 m)² + h² = (26 m)²   ⇒   h² = 576 m²   ⇒   h = 24 m

This height is common to all three shapes.

Now find the area of each shape.

• right triangle:

1/2 × (10 m) × (24 m) = 120 m²

• parallelogram:

(40 m) × (24 m) = 960 m²

• other triangle:

• 1/2 × (20 m) × (24 m) = 240 m²

Then the total area of the shaded region is 1320 m².

Step-by-step explanation:

y = kx, where k is a real constant.

When x = 12, y = 60.

=> (60) = (12)k, k = 5.

Therefore when x = 20,

y = kx = (5)(20) = 100.

Answer:

It would be C  , 7 root 2

Step-by-step explanation:

you would have to find the Sin of 45. So you set up a proportion ( you can do this on a calculator)

sin 45=7/x and then calculate that and solve.

If you dont have a calc then the sin of 45 is 1/root2

The width of the new rectangular field would be 0 meters, which means it would essentially be a line segment.

To find the length and width of another rectangular field that has the same perimeter but a larger area, we can use the following steps:

1. Calculate the perimeter of the given rectangular field:

  Perimeter = 2 * (Length + Width)

            = 2 * (120 meters + 80 meters)

            = 2 * 200 meters

            = 400 meters

2. Divide the perimeter by 2 to find the equal sides of the new rectangular field. Since the perimeter is divided equally into two sides, each side would be half of the perimeter length:

  Side length = Perimeter / 2

             = 400 meters / 2

             = 200 meters

3. Now, we have the side length of the new rectangular field. However, we need to determine the length and width that would yield a larger area. One way to achieve this is to make one side longer and the other side shorter.

4. Let's assume the length of the new rectangular field is 200 meters. Since both sides have the same length, the width can be calculated using the formula for the perimeter:

  Width = Perimeter / 2 - Length

        = 400 meters / 2 - 200 meters

        = 200 meters - 200 meters

        = 0 meters

5. Therefore, the width of the new rectangular field would be 0 meters, which means it would essentially be a line segment. However, note that the question asks for a rectangular field with a larger area. Since the width cannot be zero, we can conclude that it is not possible to have a rectangular field with the same perimeter but a larger area than the given field.

In summary, it is not possible to find another rectangular field with the same perimeter but a larger area than the rectangular field with dimensions 80 meters wide and 120 meters long.

Answer: See explanation

Step-by-step explanation:

Let the number of regular trucks be a

Let the number of dually trucks be b.

From the question,

a + b = 73 .......... i

4a + 6b = 354 .......... ii

Multiply equation i by 4

Multiply equation ii by 1

4a + 4b = 292 ........ iii

4a + 6b = 354 ........ iv

Subtract iii from iv

2b = 62

b = 62/2

b = 31

The number of dually trucks = 31

Since a + b = 73

a + 31 = 73

a = 73 - 31

a = 42

The number of regular trucks = 42

Answer: answer is 72 you can  get it by either multiplying the height and the base by two and following the formula for area of a triangle or you can divide 36 by two and multiply that by 4

36 divided by 2 = 18

Each triangle is 18 meters

18 x 4 triangles = 72 meters

Answer:

x = -61

Step-by-step explanation:

-  2x - 35 = 87.    

         +35. +35.   Add 35 to both sides

-2x = 122.  

-2/-2 = 122/-2.     Divide by -2 on both sides

     x = -61

The resulting equation if Becca isolated x² in the first equation and then substituted it into the second equation is (9-y²) / 25 - y²/36 = 1

x² + y² = 9

x²/25 - y²/36 = 1

From (1)

x² = 9 - y²

substitute x² = 9 - y² into (2)

x²/25 - y²/36 = 1

(9-y²) / 25 - y²/36 = 1

Therefore, the resulting equation is option C; (9-y²) / 25 - y²/36 = 1

Answer:

(9-y²) / 25 - y²/36 = 1

Step-by-step explanation:

The greatest possible difference between David's result and Armen's result is 5.

Let's first consider the maximum number of odd shirts Armen can count. Since there are only 5 odd numbers between 1 and 9, the maximum number of odd shirts Armen can count is 1+3+5+7+9 = 25.

Now, let's consider the maximum number of even shirts David can count. Since there are only 4 even numbers between 1 and 9, the maximum number of even shirts David can count is 2+4+6+8 = 20.

Therefore, the greatest possible difference between David's result and Armen's result is

= 25 - 20

Subtract the numbers

= 5

The maximum difference occurs when Armen counts all 5 odd shirts and David counts all 4 even shirts.

The statistical procedure for analyzing the results of multiple studies to reach an overall conclusion is known as meta-analysis.

Meta-analysis is a statistical technique used to combine and analyze data from multiple independent studies on a specific research question or topic. It involves systematically reviewing and synthesizing the results of individual studies to draw an overall conclusion or estimate the effect size of an intervention or phenomenon.

In a meta-analysis, researchers collect data from each study, including the study design, sample size, and effect size measures. The effect size represents the magnitude of the observed effect or relationship of interest. By pooling the effect sizes across studies, researchers can assess the overall effect and test its statistical significance.

Meta-analysis provides several advantages, including increased statistical power due to larger sample sizes, the ability to generalize findings across multiple studies, and the opportunity to identify patterns or sources of heterogeneity across studies.

Overall, meta-analysis is a valuable statistical procedure that allows researchers to synthesize and interpret findings from multiple studies, providing a more comprehensive and robust understanding of a research topic.

The probability that exactly 17 households own a DVD player is 0.0124.

Given:

The probability that a house hold in centercity owns a DVD player is = 53%.

So, p = 0.53

The probability that a house hold in centercity does not own a DVD player is = 100% - 53% = 47%

So, q = 0.47

The sample size is 22 households in the city.

So, n = 22

We have to calculate the probability that exactly 17 households own a DVD player.

So, r = 17

The formula to be used in binomial experiment is:

P (r) = \(\frac{n!}{r! (n -r)!}\) × \(p^{r}\) ×\(q^{n-r}\)

The probability that exactly 17 households own a DVD player will be,

= \(\frac{22!}{17! (22 - 17)!}\) × \(0.53^{17}\) ×\(0.43^{22-17}\)

= \(\frac{22!}{17! (5)!}\)× \(0.53^{17}\) ×\(0.43^{5}\)
