Elanso [62]4 years ago
8 0

Answer:

Khalid = 140 mph

Jesse = 150 mph

Jesse has the faster train

Step-by-step explanation:

Khalid is travelling 140 mph because 280/2 is 140

Jesse is travelling at 150 mph because just like the question stated, y=150x where "x" is the total hours they traveled and 150 is the distance she traveled.

Jesse is faster because 150>140

A sum of money is divided in the ratio 2 : 3 : 7 .Given the largest share is $112,calculate the smallest share.
emmasim [6.3K]

Answer:

$32

Step-by-step explanation:

A sum of money is divided in the ratio 2:3:7.

Let the share of each individual be represented by 2x,3x,7x respectively.

The largest share (7x) is given as $112.

\[7x = 112\]

\[=>x = \frac{112}{7}\]

\[=>x = 16\]

So the respective shares are \[2\times16,3\times16,7\times16\]

In other words, the shares are 32,48,112.

So the smallest share is $32

Find the x- and y-intercept of the line.<br><br> -7/5x -4y = 7
rosijanka [135]
First, isolate the variables to either side.

4y = -7/5x -7

Second, simplify in terms of y.

y = -7/20x - 7/4

Third, plug 0 in for y to find the y intercept and factor the x side to make it simple. Then, find the value that makes the x-factor zero.

0 = (-7/4)(1/5x +1)

1/5x + 1 = 0

1/5x = -1

x = -5

The x-intercept is (-5,0)

Fourth, plug zero in for x to find the y-intercept.

y = -7/20*(0) -7/4

y = -7/4

Therefore, the y-intercept is (0,-7/4) and the x-intercept is (-5,0).

Find the shaded area of the basketball court to the nearest foot.
Trava [24]
So the image consists of 1 rectangle and half a circle.
Rectangle - 12*19 = 228Half a circle - \pi r^2 =  \pi 6^2 = 36 \pi /2 = 18 \pi
In the end there are 2 rectangles (2*228 = 456) and 1 full circle (18*2 = 36), which makes the shaded area 456ft and 36\pi
