Answer:76.65
Step-by-step explanation:
First, you write 36.5 times 2.10
Then, multiply them.
That equals 76.65
Option B
5 hundredths is not the way to express 0.50
<h3><u>Solution:</u></h3>
Given that Three of the choices are ways to express 0.50
To find: wrong option
Let us first write 0.50 in different ways
<h3><em><u>
To convert a Decimal to a Fraction follow these steps:
</u></em></h3>
Step 1: Write down the decimal divided by 1, like this: decimal 1.
Step 2: Multiply both top and bottom by 10 for every number after the decimal point. ...
Step 3: Simplify (or reduce) the fraction.

means 50 hundredths
<h3>Therefore option D is correct</h3>
On simplifying
we can write,

means one half
<h3>Therefore option A (one half) is correct</h3>
Similarly, \frac{5}{10} means 5 tenths
<h3>Therefore Option C is also correct</h3>
Thus the wrong option is B
<em><u>Justification:</u></em>
5 hundredths can be written as:

Therefore option B is wrong
Answer:
2 :3
Step-by-step explanation:
To take the scale factor from the area to length we take the square root of each
sqrt(4) : sqrt(9)
2 :3

Answer:
7hr 12 min
Step-by-step explanation:
Given that
Bob can type 2 letters in 4 hours
while on the other hand bill can do it in six hours
We need to find out the no of hours in which they type 6 hours
So,
Bob's rate is
= 2 ÷ 4
= 1 ÷ 2 letter per hour
And,
Bill's rate is
= 2 ÷ 6
= 1 ÷ 3 letter per hour
Now
Together rate is
= 1 ÷ 2 + 1 ÷ 3 = 5 ÷ 6 letter per hour
We know that
rate × hours = production
Let us assume the hours be x
So,
(5 ÷ 6)x = 6
x = (6 ÷ 5) × 6
x = 36 ÷ 5
= 7 1 ÷ 5
= 7hr 12 min
