ANSWER
The car moves at 32 mi/hr
EXPLANATION
This question is asking us to determine how fast is a train that makes 330 mile trip in 4 hours.
This is the same as calculating the speed of the train:
Speed = distance covered/time taken
The distance covered is 330 mile
The time taken is 4 hours.
Speed =330/4 =82.5 mi/hr
Answer: B) 2
Detailed Answer:
The degree of a polynomial is the highest power in the polynomial. Here the highest power is 2 hence the degree is 2. Polynomials with the degree 2 are also called quadratic polynomials.
Answer:
84
Step-by-step explanation:
To get from 4 to 12, you multiply with 3.
Everything is 3 times as big in the larger rectangle.
This includes the perimeter.
Example:
small rect 4x10, perimeter 4+4+10+10 = 28
large rect 12x30, perimeter 12+12+30+30 = 84
but also 28x3 = 84
Answer:
dimensions of the seat are 2 feet and 8 feet
Step-by-step explanation:
given data
area = 16 square feet
length = 4 times greater than the width
solution
we know that area is express as
Area = L × W .................1
here L is length and W is width
put here value we get
16 = L × W ...............2
and we know
L = 4W ( as given ) ...............3
so put that in equation 2 we get
16 = 4W × W
4W² 16
solve it we get
W = 2
so here put this value in equation 3 we get
L = 4 × 2
L = 8
so the dimensions of the seat are 2 feet and 8 feet
