<span>Answer: 199.81
Given:
1 hundred
9 tens
9 ones
8 tenths
1 hundredths
thus;
1 hundred = 1 x 100 = 100
9 tens = 9 x 10 = 90
9 ones = 9 x 1 = 9
8 tenths = 8 x 1/10 = 8/10 or .8
1 hundredth = 1 x 1/100 = 1/100 or .01
add: 100 + 90 + 9 + .8 + .001 = 199.81
That is: one hundred ninety-nine and eighty-one hundredths</span>
The area of a regular octagon is given by:
A = (4) * (L) * (ap)
Where,
L: side
ap: apotema
Substituting values we have:
A = (4) * (19) * (16)
A = 1216 square inches
Answer:
The area of a regular octagon with an apothem 16 inches long and a side 19 inches long is:
A = 1216 square inches
Answer:
Step-by-step explanation:
1) 9.5 x 0.14
= 19/2 x 7/50
= 133/100
= 1.33
9.5 - 1.33
= <u><em>8.17</em></u>
<u><em></em></u>
2) 60 - 46.20 / 60
= 13.80 / 60
= 0.23
= <u><em>23% decrease</em></u>
Hello!
ANSWER:
36 students have a dog as a pet, and 30 students have a cat as a pet.
EXPLANATION:
Let's quickly convert these fractions to decimals by dividing their numerators by their denominators.
4 ÷ 5 = 0.8
2 ÷ 3 = 0.6666666667
Now, multiply the decimal forms by the number of students in Mrs. Hu's class.
0.8 × 45 = 36
0.(6)7 × 45 = 30
Conversion factors are ratios of equal qualities.
