Answer:
87.48
Step-by-step explanation:
First find the area of the square
12^2=144
find area of the 2 circles
9*3.14
but theres 2
18*3.14=56.52
144-56.52=87.48
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
Answer:
<em>The quotient will be between 18 and 19.</em>
<em>Estimated quotient will be 18.75</em>
Step-by-step explanation:
The closest number to 75 which is divisible by 4 and <u>less than 75</u> is : 72 and
the closest number to 75 which is divisible by 4 and <u>greater than 75</u> is : 76
Now,
and 
That means, the quotient for
will be between 18 and 19.
As, 75 is 1 less than 76, so the quotient will be
or
less than 19.
So, the quotient will be:
