Answer: B
Step-by-step explanation:
Perimeter = 2(length+width)
'CD' = 20×cos(30) = 17.3205
width 'AD' = 20×cos(60) = 10
Perimeter = 2(17.3205+10)
= 2(27.3205)
= 54.641 =54.6
First, find the value of x. Note that the angles x, 0.5x and 3x sum up to 4.5x, and that this sum has the value 180 degrees. Solving this equation for x, we get x = 40 degrees.
Now, 0.5x and 0.5y are vertical angles, and thus x = y. So, with x being 40 degrees, y = 40 degrees.
Answer:
2.4 kilograms
Step-by-step explanation:
Given: 5 people are evenly sharing 12 kilograms of apples
To find: quantity of apples that each person should get
Solution:
Use the unitary method to get the required answer.
Under unitary method, if the value of multiple items is given to us, divide the total value by the number of items to obtain the value of one item.
Quantity of apples for 5 people = 12 kilograms
Quantity of apples for 1 person = kilograms
So, each person should get 2.4 kilograms of apples.
X= -9
Steps
Move 7 to the right of the equal sign and change to a negative
1x= -2-7
1x=-9
Starts off at 7 ends at114688, subtract them, 114681. Now there are 8 terms so subtract 1 because you're starting from the beginning, that leaves 7. Now divide 114681/7=16,383 difference per point,
Now 1st pt is 7
2nd is 16390
3rd is 32773
4th is 49156
5th is 65539
6th is 81922
7th is 98305
8th is 114688
Now add these= 458780
