Answer:
Tammy takes 5 hours to drive 335 miles.
Step-by-step explanation:
Given that :-
- Tammy drove 871 miles in 13 hours.
To find :-
How long would it take her to drive 335 miles ?
Solution :-
Let us assume that it take her to drive 335 miles in x hours.
To find x, we need to find it in ratios.
871 miles = 13 hours
335 miles = x hours
Using cross multiplication method
871 × x = 335 × 13
multiply to get
871 x = 4, 355
divide each side by 871
871 x / 871 = 4,355 / 871
x = 5
hence, Tammy takes 5 hours to drive 335 miles.
Rational numbers are sometimes natural numbers.
Since the equation is in y = mx+b form you can easily determine the y intercept based on the b value present.
Y = mx + b
Y = 2x - 3
B = y intercept = (0,-3).
Answer:
30
Step-by-step explanation:
We require to calculate the volume of 1 brick
V = lbh ( l is length, b is breadth and h is height ), that is
V = 14 × 8 × 5 = 560 cm³
Now divide the volume of concrete available by the volume of 1 brick.
number of bricks made = 
= 30
