The perimeter of a triangle is 82 feet. One side of the triangle is 2 times the second side. The third side is 2 feet longer tha

Butoxors [25]

Answer:

Side 1: 40 feet

Side 2: 20 feet

Side 3: 22 feet

Step-by-step explanation:

Side 1 is twice the length of side 2 and side 2 is 20 feet, which means side 1 is 40 feet. Side 3 is the the length of the second side plus 2, which means it has a length of 22 feet.

If B is the midpoint of AC, and AC= 8x-20, find BC.

Semmy [17]

Answer:

BC = 4x-10

Step-by-step explanation:

$\because B$ is the midpoint of AC.

$\therefore BC = \frac{1}{2} AC$

$\therefore BC = \frac{1}{2} (8x-20)$

$\therefore BC = \frac{1}{2} \times 2(4x-10)$

$\huge \purple {\boxed {\therefore BC = 4x-10}}$

Sherelle and Venita find two bags of coins in their grandmother’s attic. Each girl selects a bag, takes a random sample of 20 co

S_A_V [24]

Answer:

Step-by-step explanation:

Hello!

The five-number summary comprehends the minimum and maximum values, the 1st and 3rd quartiles and the median.

1st step: is to arrange the data sets from least to greatest.

Sherelle:

26 39 56 58 60 62 65 66 66 68 71 72 72 73 74 75 81 83 84 85

Venita:

44 45 51 51 53 53 55 57 58 62 65 66 69 69 70 73 75 77 78 79

2nd step: To calculate each quartile you have to determine their position and then identify which observation sits in that position:

Quartile 1:

PosQ₁: n/4= 20/4= 5

Quartile 2 (Median)

PosMe: n/2= 20/2= 10

Quartile 3

PosQ₃: n*(3/4)= 20*(3/4)= 15

Since both samples have the same size, the 1st quartile will be the fifth observation of each sample, the median will be the tenth observation and the 3rd quartile will be the fifteenth.

Sherelle:

Q₁: 60

Me: 68

Q₃: 74

Minimum: 26

Maximum: 85

Venita:

Q₁: 53

Me: 62

Q₃: 70

Minimum: 44

Maximum: 79

I hope this helps!

In the 30-60-90 triangle below, side s has a length of<br> and side q has a<br> length of

zaharov [31]

Answer:

Step-by-step explanation:

The Pythagorean triple for a 30-60-90 triangle is, in terms of patterns,

(x, x√3, 2x) where x is the length of the side across from the 30 degree angle, x√3 is the length of the side across from the 60 degree angle, and the length of the hypotenuse is represented by 2x. We have the length of the hypotenuse given as 10. Therefore:

2x = 10 (the formula for the length of the hypotenuse is set equal to the value of the hypotenuse, allowing us to solve for x) so

x = 5. Look up above at the triple. The side length across from the 30 degree angle measures x; if x = 5, then side s = 5.

The formula for the side length across from the 60 degree angle is x√3, and again, if x = 5, side q = 5√3 which is choice C.
