Step-by-step explanation:
we know that
To determine the rate per pretzel or unit rate, divide the total paid by the number of pretzel
so
<em>Jaimie's error</em>
He subtracted 42 from $126 when he should have divided $126 by 42
Replace x with 2+i and solve
Remember that i is the square root of -1
My phone automatically capitalizes I, so don’t be confused by that!
y=(2+I)^2 + 3(2+I) +5
y=4+4i-1+6+3i+5
y=7i+14
Answer:
-1.75 or -1 3/4
Step-by-step explanation:
each line is 1/4 since you need 4 lines to get to the next number.
the number falls on the third line out of 4 lines
Answer:
A vector ⇒ answer D
Step-by-step explanation:
* Lets revise some definition to solve the problem
- <em>Speed = distance ÷ time</em>
∵ Distance has no direction
∴ Speed has no direction
∴ Speed is a scalar quantity ⇒ (magnitude only)
- <em>Velocity = displacement ÷ time</em>
∵ Displacement has direction
∴ Velocity has direction
∴ Velocity has magnitude and direction
∵ Any vector has magnitude and direction
∴ Velocity is a vector quantity
∵ Velocity describes both speed (magnitude) and direction
∴ Velocity is a vector
Answer:
0.212 sq-m
Step-by-step explanation:
(refer to attached)
Volume of a cylinder is given by
V = πr² h, where 3 is the radius and h is the height
in this case, h is given as the length of the cylinder of 3 m
r is given to be (3/20)m
hence,
V = πr² h
V = π(3/20)² (3)
V = π (9/400) (3)
V = π (27/400) (assuming π = 3.142)
V = 3.142 (27/400) = 0.212 sq-m
