Answer:
7 : 17.29
Step-by-step explanation:
==>Given:
Two similar cylinders:
Surface area of Cylinder A = 49cm²
Surface area of Cylinder B = 121cm²
==>Required:
Scale factor between both cylinders
==>Solution:
We can easily get the scale factor between both by taking the following steps:
=>Set up a ratio of their surface area:
Smaller cone surface area : larger cone surface area
49:121
= 49/121
=>Simplify the ratio gotten:
Dividing the denominator and the numerator by 7, would give us,
7/17.29
= 7:17.29
Answer:
Step-by-step explanation:
<h3>Forming linear equations and solving:</h3>
Cost = fixed rate + number of guests* cost per meal.
Let x be the number of guests.
a) Pin hall:
Fixed rate = $ 500
Cost per meal = $15
Cost = 500 + 15*x
Bloom place:
Fixed rate = $350
Cost per meal = $18
b) Given the charges are same at both halls.
350 + 18x = 500 + 15x
18x = 500 + 15x - 350
18x = 150 + 15x
18x -15x = 150
3x = 150
x = 150 ÷ 3
x = 50
When the number of guests is 50, the cost is same at both the halls
When you don't use or write the percent right.<span />
