Answer:
1a) C, D, E is over 600 cubic inches.
1b) x4.8 greater The sphere is x4.8 greater than the first cone.
Step-by-step explanation:
A) Smaller Right cylinder V≈565.49 cubic inches
B) Smaller cone V≈188.5 cubic inches
C) Cylinder right prism V≈1696.46 cubic inches
D) Right circular cone V≈565.49 cubic inches
E ) Sphere V≈904.78 cubic inches
1b) Volume of sphere/volume of smaller cone
is 904.78/188.5= 4.7998938992 = x4.80 greater.
I hope I am reading the problem right: The price of a mountain bike increased by 20% in the past year. The value is $150. What was the value of the mountain bike last year?
Let's simplify this. One year, there was this radical mountain bike that used to have an unsaid price, <em>x. </em>That year, that price of x increased by 20% more than it was before, or <em>120% times the original value</em>. Because of that, it's now $150.
We can equation this.
1.20x = 150
x = 150/1.2
x = 125
The bike, I believe, cost $125 last year. Hope this helps!
If Δ ABC is similar to ΔLMN, then angle A corresponds with angle L, B corresponds to angle M and C corresponds to N.
The sum of angles in a triangle add up to 180.
Therefore, angle A = 180- (95 +35)
= 50
but, corresponding angles are equal;
Hence angle L = 50°
