constant of proportionality: k = y/x
- plug in numbers to find:
k = 84.45 / 5
= 16.89
so, constant of proportionality: 16.89
equation:
y = kx (now plug in)
y = 16.89x
- plug in again to find the amount of cakes
y = 16.89x
895.17 = 16.89x
x = 53
53 cakes

2= 62.5
Since a triangle is equal to 180 and both sides are equal that means you'll subtract 55 from 180 which is 125 then 125/2 which is 62.5
A straight line is equal to 180 so 180-105=75
4=75
3+5=105 so
105/2=52.5
To check the answer 4+3+5=180
75+52.5+52.5=180
3=52.5
5=52.5
3 is 55. 4 is 75 because it needs to = 180 with the 105. Since
3= 55 and 4= 75 and all 3 must equal 180
45+75= 120 so 5 must be 60 because 180-120 = 60

• If one side of a triangular piece of yard area is roughly one-third the perimeter,
the second side is roughly one-fifth the perimeter, and the third side is 7yards,
what is the perimeter of the triangle?
Answers
Answer:
15m
Step-by-step explanation:
The third side = (2/3 - 1/5) of the perimeter = 7/15 of the perimeter = 7m
The first side is 1/3 (=5/15) of the perimeter = 5m
The second side is then 3m ( or 1/5=3/15 of the perimeter).
The triangle perimeter is 15 meters (=7 m+5m+3m)

the triangle and the trapezoid have the same base area. Base b2 is twice the area the length of b1. What are the lengths of the bases of the trapezoid?
Answers
Answer: b₁ = 7 and b₂ = 14.
Triangle: base=21 cm, height=6cm
Trapezoid: height=6 cm, b1=?, b2=?
Triangle -> A=bh/2 -> A=63 (b is base and h is height)
Trapezoid -> A=[(b₁+b₂)/2)]h (b₁ and b₂ are bases and h is height)
Since they have the same area, the formula will be:
63=[(b₁+2(b₁))/2)]h
x=7
Answer:
b₁ = 7 cm, b₂ = 14 cm
Step-by-step explanation:
The area (A) of the triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here b = 21 and h = 6, then
A = 0.5 × 21 × 6 = 63 cm²
The area (A) of a trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
Here A = 63 ( same as triangle ), h = 6 and b₂ = 2b₁ , then
0.5 × 6 × (b₁ + 2b₁ ) = 63
3 × 3b₁ = 63
9b₁ = 63 ( divide both sides by 9 )
b₁ = 7
and b₂ = 2 × 7 = 14
The bases of the trapezoid are 7 cm and 14 cm
