Answer:
where x denotes height of Allie
Step-by-step explanation:
An inequality compares two values. One value is less than, greater than, or not equal to another value.
Given: Allie is waiting to be tall enough to ride the thunder dragon roller coaster. You have to be at least 60 inches to ride.
To write: an equality
Solution:
Let the height of Allie be x inches.
As a person has to be at least 60 inches to ride,
the inequality can be
Answer:
The answer is 452.16 cm³.
Formula to calculate the volume of cone = V = πr²x h/3
Now r = 6 cm and h = 12cm, and value of π = 3.14
By putting the values,
V = (3.14) (6)² (12/3) = (3.14)(36)(4)
Answer:
The solution of the given two linear equations
x = 1 and y =1
Step-by-step explanation:
<u><em>Step(i)</em></u>:-
Given 4 x + 5 y = 9 ..(i)
- 11 x - 9 y = - 20 ...(ii)
Multiply 11 by (i) and multiply 4 by (ii)
44 x + 55 y = 99 ...(a)
- 44 x - 36 y = -80...(b)
Adding above equations (a) and (b) , we get
19 y = 19
y = 1
<u><em>Step(ii):</em></u>-
substitute y =1 in equation (i) , we get
4 x + 5 y = 9
4 x + 5 = 9
4 x = 4
x =1
<u><em>Final answer:</em></u>-
<em>The solution of the given two linear equations are</em>
<em>x = 1 and y =1</em>
<u></u>

Answer:
C. 4
Step-by-step explanation:
A pancake is circular in shape
Hence, the area of a circle = πr²
HenceThe corner shop charges
a) $12 for a 3-inch personal pancake.
For personal pancake
r = 3 inches
πr² = π × 3²
= 28.274333882 square inches
= 28.3 square inches
b) The largest pancake is a 6-inch pancake that costs $20.
For Largest pancakes
r = 6 inches
πr² = π × 6²
= 113.09733553 square inches
Approximately = 113.1 square inches
How many times larger is the area of the largest pancake than the personal pancake?
This is calculated as :
Largest pancake/Personal pancake
= 113.1/28.3
3.9964664311 inches
Approximately = 4
Option C is the correct option
