How to make 4 1/5 as a decimal?

Mathematics
1 answer:
ladessa [460]4 years ago
5 0

Answer:

4.2

Step-by-step explanation:

Because 1/5 has to be converted into the 100 as the denominator and the number you are supposed to have for the numerator so it can be easier and 4 is the whole number so it doesnt need to be in the equation.

1/5

X

20= 20/100  so now all you have to do is make that a decimal since it hasnt got to 100 or past it and you have your answer

PLEASE HELP!!!!! 13. PTS+ PLEASE SUPER EASY
Brums [2.3K]

Answer:

1. A. Set the angle and arc measures equal.

2. B. major arc

3. B. Multiply the angle measure by 2.

4. A. minor arc

Step-by-step explanation:

1. If the intercepted arc is made from a central angle then angle of arc is equal to the central angle

2. 190 is a bigger angle than 170(angle of the remaining arc)

   Therefore it is a major arc.

3.If the intercepted arc is made from a inscribed angle, then the angle of arc is double of the inscribed angle.

4. 115 < 245

   Therefore it is a minor arc.

if a model of a tower uses a scale of 1/3 inch=2ft and the actual tower is 207 feet tall what's the height of the model
stepladder [879]

<u>Answer:</u>

The height of the model  is 2 feet 10.5 inches.

<u>Step-by-step explanation:</u>

<u>Given:</u>

scale of 1/3 inch=2ft

actual tower is 207 feet

<u>To Find:</u>

The height of the model = ?

<u>Solution</u>:

We know that 1 feet is 12 inches

Then 2 feet is  12 \times 2 = 24 inches

24 inches= 72 \times \frac{1}{3}of a inch.

The tower is 72 times the scale of the model.

Now the actual tower is 207 feet

\frac{207}{72} = \frac{23}{8}, units feet

=> 2 \frac{7}{8} feet

=> 2 feet 10.5 inches.
