Answer:
D
Step-by-step explanation:
Root square of 3 is 1.732, the root square of Pi is 1.77, the root square of 8 is 2.82 and the estimated value of Pi itself is 3.14.
Answer:
32, because when you are dividing by a fraction, you can multiply by the divident by reciprocal of the divisor.
Step-by-step explanation:
4 ÷ 1/8
4/1 ÷ 1/8
4/1 × 8/1
4 × 8
32
When you are dividing by a fraction, you can multiply by the divident by reciprocal of the divisor.

There are 15 mini hotdogs and 5 mini pizza rolls in the combination meal.
Step-by-step explanation:
Given,
Calories in each hotdog = 80 calories
Calories in each mini pizza = 50 calories
Combined meal = 20
Combined calories = 1450 calories
Let,
x represent the number of hot dogs.
y represent the number of mini pizzas.
According to given statement;
x+y=20 Eqn 1
80x+50y=1450 Eqn 2
Multiplying Eqn 1 by 80
![80(x+y=20)\\80x+80y=1600\ \ \ Eqn\ 3](https://tex.z-dn.net/?f=80%28x%2By%3D20%29%5C%5C80x%2B80y%3D1600%5C%20%5C%20%5C%20Eqn%5C%203)
Subtracting Eqn 2 from Eqn 3
![(80x+80y)-(80x+50y)=1600-1450\\80x+80y-80x-50y=150\\30y=150](https://tex.z-dn.net/?f=%2880x%2B80y%29-%2880x%2B50y%29%3D1600-1450%5C%5C80x%2B80y-80x-50y%3D150%5C%5C30y%3D150)
Dividing both sides by 30
![\frac{30y}{30}=\frac{150}{30}\\y=5](https://tex.z-dn.net/?f=%5Cfrac%7B30y%7D%7B30%7D%3D%5Cfrac%7B150%7D%7B30%7D%5C%5Cy%3D5)
Putting y=5 in Eqn 1
![x+5=20\\x=20-5\\x=15](https://tex.z-dn.net/?f=x%2B5%3D20%5C%5Cx%3D20-5%5C%5Cx%3D15)
There are 15 mini hotdogs and 5 mini pizza rolls in the combination meal.
