Answer:
11 cm. if your first base is 11cm, and your second base is 13, then you need height. A=(a+b)/2 h=(13+11)/2 × 11= 132
Answer:
8.4
Step-by-step explanation:
The diagonals of a rectangle are equal.
That means WY = XZ
16x+2 = 36x-6
Subtract 16x from each side.
16x -16x+2 = 36x-16x-6
2 = 20x -6
Add 6 to each side
2+6 = 20x-6+6
8 = 20x
Divide by 20
8/20 = 20x/20
2/5 =x
We want to find the length of the diagonal
WY = 16 ( 2/5) +2
Changing to decimal form
WY =16 * .4 +2
WY =6.4+2
= 8.4
First you need to find the slope
Y2-y1/x2-x1
3-6/0-(-1)
-3/1
Slope is -1 , use a point to find b
3=-1(0)+b
3=b
The equation is
Y=-x+3
Answer: 1) 5040 and 2) 165
Step-by-step explanation:
1) Here total number of letters = 10
The number of permutations that can be formed using 4 letters at a time
= P (10, 4)
= 
= 
= 
= 
= 10 × 9 × 8 × 7
= 5040
2) Here the total number of machine = 11
The different combinations of machines can Geoff choose from to use
= 
= 
= 
= 
= 11 × 5 × 3
= 165
