Answer: She should have multiplied One-half (4) (3.5) by 5 squared.
Step-by-step explanation:
The calculation of Beth is wrong. Since Beth enlarged the triangle below by a scale of 5, she should find the area of the traingle and then multiply by 5².
This will be:
= 1/2 × 4 × 3.5 × 5²
= 2 × 3.5 × 25
= 175cm²
Given:
Principal : 7,200
Interest Rate:
Bank M : 3%
Bank K : 4%
Term : 5 years
Interest = Principal * Interest Rate * term
Bank M:
I = 7,200 * 0.03 * 5
I = 1,080
Bank K:
I = 7,200 * 0.04 * 5
I = 1,440
1,440 - 1,080 = 360
Jim will pay 360 more interest if he takes the $7,200 loat at a 4% interest rate for a 5-year term.
Answer:
Sarah's, 2 inches.
Step-by-step explanation:
Given:
Sarah cut off 1/8 of a 48 inch piece of ribbon.
Jane cut off 1/9 of a 36 inch piece of ribbon.
Question asked:
Whose piece is longer ?
How much longer ?
Solution:
As Sarah cut off 1/8 of a 48 inch piece of ribbon, means she has cut piece of size:
As Jane cut off 1/9 of a 36 inch piece of ribbon, means she has cut piece of size:

As Sarah has 6 inches piece of ribbon and Jane has 4 inches piece of ribbon so Sarah's piece longer.
Now, to find it is how much longer we will subtract Jane's piece of ribbon from Sarah's piece of ribbon,
6 inches - 4 inches = 2 inches.
And hence, Sarah's piece of ribbon is 2 inches longer than Jane's piece of ribbon .
It would be a - f / c = h
