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.
Answer:
Step-by-step explanation:
This quadratic models the parabolic motion equation
where h is the height of the object after the motion occurs, a is the pull of gravity, v(i) is the initial vertical velocity of the object, and h(i) is the height from which the object was initially launched. If we are looking for when the ball hits the ground, h = 0, because the height of an object on the ground has no height at all (or 0 height). To find the time the object was in the air, factor the quadratic and solve for the values of t.
Two factors of 4 that add up to be 3 and multiply to be 4 are -1 and 4. So t=-1 and t = 4. Since we know that time can never be negative, then t = 4 seconds.
Here,
Perimeter (P)=86 feet
Length (l)=25 feet
Let, width(b)= x feet
Then,
Perimeter= 2(l+b)
86=2(25+x)
43=25+x
x=18
Hence, required width is 18 feet...
They are all correct except in 5), 4+8 is 12, not 13.
Answer:
The answer is "Option D".
Step-by-step explanation:
A line is a horizontal 1D-dimensional representation without any thickness and extends in every way. It sometimes is also known as the straight line. The line, which connects two planes lies simultaneously on both planes, that's why in this question only "option D" is correct.
