Answer:

81/4

Step-by-step explanation:

By the Pythagorean theorem, the length of the altitude drawn from the hypotenuse is

[tex] \sqrt{65} [/tex]

This means that by the geometric mean theorem, that out of the two segments the hypotenuse is split into, the one with unknown length has length 65/4.

Thus, x = 65/4 + 4 = 81/4.

Answer:

100π

Step-by-step explanation:

The formula for the surface area of a sphere is SA = 4πr^2, where r is the radius of the sphere and SA stands for surface area. We are given that the radius is 5, so if we plug this into the formula, we get that SA = 4π*(5)^2, or SA = 4 * 25 * π. If we solve it out, we get 100π. If the software wants you to let π be 3.14 and evaluate, you will get approximately 314. I hope this helps

The other possible names of ∠RPE are ∠P and ∠EPR

The angle is given as:

∠RPE

The angle is named after the middle alphabet.

The middle alphabet in ∠RPE is P

This means that ∠P is a possible name for ∠RPE

Also, the positions of R and P can be interchanged.

So, we have:

∠EPR

Hence, the other possible names of ∠RPE are ∠P and ∠EPR

By applying Pythagorean's theorem, the missing side of this right-angled triangle is: A. 7√3 inches.

By critically observing the triangle shown in the image attached below, we can logically deduce that it is a right-angled triangle. Thus, we would find the missing side by applying Pythagorean's theorem:

z² = x² + y²

Also, the sides of this right-angled triangle are:

Substituting the given parameters into the formula, we have;

14² = x² + 7²

196 = x² + 49

x² = 196 - 49

x² = 147

x = √147

x = √49 × √3

x = 7√3 inches.

The length of the shortest side of the hexagon is; 41.833 inches

Let the length of the shortest side of the hexagon be x. Now, a hexagon has six sides and if the next side is 10 inches longer than the previous side, then the length of the six sides are;

x, x + 10, x + 20, x + 30, x + 40, x + 50

Perimeter is given as 401 inches. Thus;

x + x + 10 + x + 20 + x + 30 + x + 40 + x + 50 = 401

6x + 150 = 401

6x = 401 - 150

6x = 251

x = 251/6

x = 41.833 inches

The formula to find the nth term of the AP is 8 + 3(n - 1).

a = first term = 8

d = common difference = 3

The nth term will be:

= a + (n - 1)d

= 8 + (n - 1)3

= 8 + 3(n - 1)

The age of the 4th student will be:

= a + (n - 1)d

= 8 + (4 - 1)3

= 8 + 9

= 17 years

The sum of total ages if there are 20 students in a row will be:

= n/2[2a + (n - 1)d]

= 20/2 [2×8 + (20 - 1)3]

= 10 [16 + (19 × 3)]

The percentage of runners that have times less than 14.4 seconds that is P(x<14.4) is 0.0013499 which is approximately = 0.15%.

The standard deviation of a data set is defined as how the data is dispersed in relation to the mean.

From the question,

The raw time given (X) = 14.4 sec

The mean value(m) = 18sec

The standard deviation(d) = 1.2 sec

Using the formula,

z = X - m/ d

z= 14.4- 18/1.2

z = -3.6/1.2

z= -3

Using a Z table to find the percentage equivalent of P(x<14.4) is 0.0013499 which is approximately = 0.15%.

Therefore, the percentage of runners that have times less than 14.4 seconds that is P(x<14.4) is 0.0013499 which is approximately = 0.15%.

AB = AC, they are equivalent. Since an isosceles triangle has the congruent angle property, mB = mC cannot be shown until AB=AC.

Generally, Isosceles triangles are those that have two sides that are equal in length and two angles that are also equal in size.

Hence The sides and angles theorem for triangles., and the side AB is equal to the other side AC,

In conclusion, Assuming that the base angles, mB, and mC, are of equal measure, the triangle sides and angles theorem states that segment AC is larger than AB. The bigger angle of a triangle is always opposite to the longer side, according to the theorem.

Step-by-step explanation:

let x be the number of one- bedroom and y the number of two - bedroom apartments , then create 2 equations and solve simultaneously.

x + y = 12 ( subtract y from both sides )

x = 12 - y → (1)

360x + 450y = 4950 → (2)

substitute x = 12 - y into (2)

360(12 - y) + 450y = 4950 ← distribute parenthesis and simplify left side

4320 - 360y + 450y = 4950

4320 + 90y = 4950 ( subtract 4320 from both sides )

90y = 630 ( divide both sides by 90 )

y = 7

there are 7 two- bedroom apartments
