The two cities are actually 427.5 miles apart.
Answer:
x = 5.5 (nearest tenth)
Step-by-step explanation:
let x be the length of 1 side
given area of square poster is 30 in²
and
Area = (length of 1 side )²
hence
30 = x²
x = √30
x = 5.4772
x = 5.5 (nearest tenth)
Answer:
Step-by-step explanation:
Then the x part of the point takes on the opposite sign that it currently has.
- Right now it is 1. If it takes on the opposite sign, it becomes - 1
- So the new point is (-1,-5).
- Nothing happens to the - 5 when reflected across the y axis.
Answer:
162km
Step-by-step explanation:
dis=30km
time=5/12hr
speed =(dis÷time)
30÷5/12
30×12/5=72km/h
sp=72km/h
time=21/4hr
dis= sp×time
72×9/4=162km
Answer:
The correct option is;
Yes, his calculations are correct and the volumes for figures are equal
Step-by-step explanation:
The volume, V, of a square (of side s) pyramid of height h = 
Where:
s = 9.7 inches
h = 9 inches
We have;
The volume, 
, of a cylinder of radius r = Base area × Height, h = (π×r²)×h
Where:
Base area = π×r²
r = Radius of the cylinder = 5.47 inches
h = Height of the cylinder = 3 inches
= π × 5.47² × 3 = π × 29.9209 × 3 = π × 89.7627 = 281.998 ≈ 282 m³
Therefore, Jude is correct.
