Todd plans to swim 900 yards in a pool. So far Todd has swam 720 yards. What percentage of the total has Todd completed?

2 answers:

7 0

Ok, so the answer is 80%. How I got this, I did the cross-product method. On one side, I did x/100, and the other, I did 720/900. And I multiplied 720 by 100, and got 72,000. And I also did 900 Times x, and got 900x. So, the new equation is 72000 = 900x. I divided 72000 by 900, and got 80, which is the percentage. (Picture of Cross-Product Method)

Deane is flying to a destination that is 2745 miles away. The plane's average speed is 450 mph. Write the slope-intercept form o

Dmitriy789 [7]

The equation in y = mx+b form is y = -450x+2745

where,
x = number of hours that have passed by
y = distance to destination in miles

The y intercept is 2745 since this is the initial starting y value, aka the starting distance. Therefore b = 2745.

The slope is -450 or -450/1 since for each hour, the distance goes down by 450. You can think of it as
slope = (change in y)/(change in x)
slope = (change in distance)/(change in time)
slope = (-450 miles)/(1 hour)
slope = -450

Write the fraction as the sum of two fractions with the same denominator

1/4 + 1/4 = 1/2

I got 1/2 because if you add 1/4 and 1/4 you'd get 2/4, and when you simplify 2/4 you'd get 1/2.
