Answer:
19.2
Step-by-step explanation:
Cosine rule :
c will always be the hypotenuse.
a and b can be any if the opposite or the adjacent.
\sqrt{369}=19.20937...
First I did 8*6 which is 48 ( meaning there is 48 slices total)
Then take 36 and subtract that from 48 getting 12.
So there is 12 slices of pizza left over.
Since we know it is between 80 and 99, the tens place can only either be 8 or 9.
If it is 8, the ones place is 5 since the digits must add to 13.
If it is 9, the ones place is 4 since, once again, the digits must add to 13.
Our options are 85 or 94. Based on the last clue, it is 85 since 8-5=3.
Final answer: 85
Given:
total of 21 children
2 times as many girls as boys at the party.
Let x be the number of boys.
boy + girls = 21
x + 2x = 21
3x = 21
x = 21/3
x = 7 number of boys
2x = 2(7) = 14 number of girls.
C. Divide 21 ÷ 3. Subtract the quotient from 21.
D. <span>Divide 21 ÷ 3. Multiply the quotient by 2.</span>
