Answer:
the answer should be B
Step-by-step explanation:
the first part is basically finding the difference between the terms, as we know that d=T2-T1
so by comparing the T2-T1 and T3-T2 we can find the difference with the two variables h and k
afterwards do the same with T4-T3 and T3-T2, comparing them and you will get another equation
now that you have two equations, you can do simultaneous equation to get the answers
hope i helped :D
we have
4 yards 24 inches wide
6 yards long
<u>step 1</u>
convert inches to yards
we know that
1 yard is equal to 36 inches
so
24 inches=(24/36)=2/3 yards
so
4 yards 24 inches wide=4+(2/3)=14/3 yards
step 2
Find the ratio
W/L=(14/3)/(6)=14/18=7/9
therefore
<u>the answer is </u>
the ratio is equal to (7/9)
Answer:
2.33 Seconds
Step-by-step explanation:
The equation y = -6t^2 - 10t + 56 expresses the height of a ball at a given time, t, on the planet Mars. We are also given that the ball is thrown with a velocity of 10 feet per second with the initial height of 56 feet.
To find the amount of time to reach the ground, we can say that the time being found will be when the ball is on the ground, or when y = 0. So we simply set our equation to 0 and solve for t.
y = -6t^2 - 10t + 56
0 = -6t^2 - 10t + 56
0 = -1 (6t^2 + 10t + -56)
0 = -1 (3t - 7) (2t + 8)
(3t - 7) = 0 OR (2t + 8) = 0
3t = 7 OR 2t = -8
t = 7/3 OR t = -4
Since time will not be negative, we will want to choose the positive solution for this quadratic equation.
Hence, the amount of time for the ball to hit the ground will be 7/3 seconds or 2.33 seconds.
Cheers.
