Answer:
616
Step-by-step explanation:
The equation to find the area of a trapezoid is: A = ½ (b
+b²) h.
b1=43
b2=45
h=14
Plug the variables in and solve.
Answer:
7) a = 65; b = 50
8) c = 125; d = 55; e = 52
9) f = 105
Step-by-step explanation:
7)
a = 65
b + 130 = 180
b = 50
8)
c = 125
d + 125 = 180
d = 55
e = 52
9)
(180 - f) + 32 + (180 - 107) = 180
180 - f + 32 + 180 - 107 = 180
-f + 285 = 180
-f = -105
f = 105
For the lateral area, don't include the base area. For the surface area, you should include it.
Equation 1) 10x + 2y = 30
Equation 2) 4x + y = 4
Multiply all of equation 2 by 2.
2) 2(4x + y = 4)
2) 8x + 2y = 8
1) 10x + 2y = 30
Subtract equations from each other.
-2x = -22
Divide both sides by -2.
x = -22/-2
x = 11
B) x = 11
~Hope I helped!~
Answer:
Qestion 1: First option.
Question 2: It's actually false, because we know that Eugene doesn't want to spend any more than 5, so 5 goes where the last x is.
Question 3: Last option.
Question 4: The order it's in seems correct, but I'm not 100% sure.
Step-by-step explanation:
Please don't be mad if it ends up being wrong, I tried. Hope you pass :)
