Answer:
Step-by-step explanation:
Yes, because you have to add the like terms (14m and -6m which equals 8m) +9
Answer:
1.80 in^3
1.0 fluid ounces^3
Step-by-step explanation:
volume of a cone = 1/3 πr²h
π = 3.14
r = 2.2 / 2 = 1.1
h = the value of h can be determined using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
1.8² = 1.1² + b²
3.24 = 1.21 + b²
3.24 - 1.21 = b²
2.03
b = √2.03 = 1.42
Volume = 1/3 x 3.14 x 1.21 x 1.42 = 1.80 in^3
1.80 x 0.554 = 1.0 fluid ounces^3
The expression that represents the amount mother spent is 4 × 5.00 + 2.00.
This outing will cost $22.00.
Solution:
Number of members in a family = 4
Cost of one ticket = $5.00
Cost of soft drink = $2.00
Mother spent = Number of members × Cost of each ticket + Cost of soft drink
= 4 × 5.00 + 2.00
The expression that represents the amount mother spent is 4 × 5.00 + 2.00.
To solve this expression using PEDMAS rule.
First do multiplication.
4 × 5.00 + 2.00 = 20.00 + 2.00
Now do addition.
4 × 5.00 + 2.00 = 22.00
Hence this outing will cost $22.00.
