Step-by-step explanation:

I just answered this for someone else... here is the same answer I gave them

QR + RS +SQ = perimeter

2(XR) + 2(YS) + QS = perimeter ( b/c multiplication is communicative  SQ=QS)

2*5 +  2 * 7 + 20 = perimeter

10 + 14 + 20 = p

44 = p

the answer is A plus or minus square root of 50

Step-by-step explanation:

First, you have to find the total number of socks. The total is 14. Now, since you choose 2 socks out of 14 in total, the probability is 2/14 or about 14%. To find the percent, just divide the numerator by the denominator. The answer you get is in decimal form. Multiply the decimal by 100. Then, there is your percent.

Option J is not supported by the data

The mean of a data set is actually the average value which is found by adding all numbers in the data set and then dividing by the number of values in the set.

The mean values of the salaries= $(50000+45000+32000+30000)/4

                                                     =$39250

Clearly we can see option H is correct.

So, average distance between each salary and mean salary is

$(10750+5750+7250+9250)/4 =$8250

Clearly, option F is correct also.

Option J is not correct because the variation of second salary with the mean is $5750 which is less than $6000.

So, option J is not supported.

Answer:

420in^2

Step-by-step explanation:

Given data

Length of base= 6 in

Widht of base= 70 in

We know that area= Length*Width

substitute

Area= 6*70

Area= 420 in^2

Hence the area of the base is 420in^2

The distance between two people or the distance of the adjacent is 150 ft.

We know a right-angled triangle has three sides they are -: Hypotenuse,

Opposite and Adjacent.

We can remember SOH CAH TOA which is,

sin = opposite/hypotenuse, cos = adjacent/hypotenuse and

tan = opposite/adjacent.

The distance of the string can be thought of as a hypotenuse which is 300 ft long.

The angle it is making with the hypotenuse is cosine 60° and the distance they are apart can be thought of as an adjacent.

Therefore, cos = adjacent/hypotenuse.

cos60° = adjacent/300.

1/2 = adjacent/300.

adjacent = 300/2.

adjacent = 150 ft.

Q. Two people are standing in a field. One person is flying a kite with a string that is 300 ft long. When the kite is directly above the second person, the cosine value of the angle made by the string and the ground is

60°, How far apart are the two people?

Answer:

Step-by-step explanation:

we can write -9 instead of x and y=1 instead of 1

so we write solution again

-9a+1b=-31

-9a-1b=-41

-18a=-72

a=4

we should write 4 instead of a

-9(4)+1b=-31

-36+b=-31

b=5

a=4
