Answer:
18 snack packs
Step-by-step explanation:
2 1/4 = 9/4 = 18 / 8
18/8 divided by 1/8 = 18
Answer:
radius=d/2 = 8/2 = 4inch.
Step-by-step explanation:
area = πr²
16π(inch)². or 352/7 (inch)².
hope this helps you.
6 + 22m
More = additionProduct = the number that is the result of multiplication6 more (+) than the product (result of) 22*Jenny's Height
If Jenny's height is 5.5 ft:6 + 22*5.5 = 6 + 121 = 127
Hope this helps clear things up a bit.

Complete Question
A boat sails 4km on a bearing of 038 degree and then 5km on a bearing of 067 degree.(a)how far is the boat from its starting point.(b) calculate the bearing of the boat from its starting point
Answer:
a)8.717km
b) 54.146°
Step-by-step explanation:
(a)how far is the boat from its starting point.
We solve this question using resultant vectors
= (Rcos θ, Rsinθ + Rcos θ, Rsinθ)
Where
Rcos θ = x
Rsinθ = y
= (4cos38,4sin38) + (5cos67,5sin67)
= (3.152, 2.4626) + (1.9536, 4.6025)
= (5.1056, 7.065)
x = 5.1056
y = 7.065
Distance = √x² + y²
= √(5.1056²+ 7.065²)
= √75.98137636
= √8.7167296826
Approximately = 8.717 km
Therefore, the boat is 8.717km its starting point.
(b)calculate the bearing of the boat from its starting point.
The bearing of the boat is calculated using
tan θ = y/x
tan θ = 7.065/5.1056
θ = arc tan (7.065/5.1056)
= 54.145828196°
θ ≈ 54.146°
X2 - 16, is the answer. The first one.
x^2 - 16 = (x)^2 - 4^2, difference of two squares :)
