answer: 80%

explanation:

to find out what percent he completed, divide what he has completed by the total number

20/25 = 0.8

now, multiply the decimal by 0.8 and multiply by 100 to turn into a fraction

0.8 x 100 = 80

so, he answered 80% so far.

i hope this helped and have a great day! if you need any further assistance with this specific question or i made any mistakes, please let me know!

What is the quotient?

AlexFokin [52]

Answer:

3/2

Step-by-step explanation:

● (-3/8) ÷(-1/4)

Flip the second fraction by putting 1 instead 4 and vice versa.

● (-3/8)* (-4/1)

-4 over 1 is -4 since dividing by 1 gives the same number.

● (-3/8)*(-4)

Eliminate the - signs in both fractions since multiplying two negative numbers by each other gives a positive number.

●( 3/8)*4

● (3*4/8)

8 is 2 times 4

● (3*4)/(4*2)

Simplify by eliminating 4 in the fraction.

● 3/2

The result is 3/2

Answer:

Parallel
Neither parallel nor perpendicular
Perpendicular

Step-by-step explanation:

Given line m:

y = 4/5x - 3

Relationship of line m with following lines:

1. y = 4/5x + 3

Same slope, different y-intercept
Parallel

2. y = -4/5x + 3

Slope are negative, different y-intercept
Neither parallel nor perpendicular

3. y = - 5/4x + 3

Slopes are negative-reciprocal, different y-intercept
Perpendicular

A ball is thrown into the air with a velocity of 34 ft/s. It's height in feet after t seconds is given by y=34t-26(t)^2. Find th

kkurt [141]

Answer:

The average velocity of the ball at the given time interval is -122.3 ft/s

Step-by-step explanation:

Given;

velocity of the ball, v = 34 ft/s

height of the ball, y = 34t - 26t²

initial time, t₀ = 3 seconds

final time, t = 3 + 0.01 = 3.01 seconds

At t = 3 s

y(3) = 34(3) - 26(3)² = -132

The average velocity of the ball in ft/s is given as;

$V_{avg} = \frac{y(3.01)-y(3)}{3.01 -3}\\\\V_{avg} = \frac{34(3.01)-26(3.01)^2-y(3)}{3.01 -3}\\\\V_{avg} = \frac{-133.223-y(3)}{0.01}\\\\V_{avg} = \frac{-133.223-(-132)}{0.01}\\\\V_{avg} =\frac{-1.223}{0.01}\\\\V_{avg} = -122.3 \ ft/s$

Therefore, the average velocity of the ball at the given time interval is -122.3 ft/s
