A+b = c+d
a+b = 770/2 ( a+b+c+d = 770)
a+b = 385
c+d = 385
a+b+a-b = 385+49
2a = 434
a = 434/2
a = 217
a-b=49
217-49= b
b = 168
c+d+c-d = 385+211
2c = 596
c = 596/2
c = 298
c-d = 211
c-211= d
298-211 = d
d = 87
Therefore, a=217, b=168, c=298, d=87
Answer:
B
Step-by-step explanation:
The volume (V) of a rectangular prism is
V = lbh
where l is the length, b the width and h the height
We are looking for 3 values that multiply together to give 10
Considering each of the options
A
100 × × = 25 ≠ 10
B
10 × × 2 = 10
C
5 × 2 × 2 = 31.25 ≠ 10
D
10 × 10 × = 50 ≠ 10
B is the only possible dimensions for the prism
Answer:
-2.1.
Step-by-step explanation:
−0.3 + (−1.8)
-0.3 - 1.8
= -2.1
midpoint= (x, y)
where x=(x1 + x2)/2
y=(y1 + y2)/2
x1=-3, x2=6, y1=5, y2=-11
so x=(-3 + 6)/2= 3/2
y=(5 + -11)/2= (5-11)/2= -6/2= -3
so mid point =(3/2, -3)
hope this helps
