2500 cubic cm is not a large container!

Let W=width
then
Depth=W/4
H=W+0.05
Volume
V=2500=W*(W/4)*(W+5)
=> W^3+5W^2-10000=0
Factor:
(W-20)(W^2+25W+500)=0
=>
W=width=20 cm.
W/4=depth=20/4=5 cm
W+5=height=20+5=25 cm

Check: 20*5*25=2500 cm^3 ok

Describe and correct the error in writing an equation of the line shown
Rudiy27

Answer:

y  = -\frac{3}{5}x+4

Step-by-step explanation:

Given:

(x_1,y_1) = (0,4)

(x_2,y_2) = (5,1)

The attachment completes the question

From the attachment, the slope of the line was calculated as:

m = \frac{1-4}{0-5}

This step is inaccurate because the slope of a line is calculated using

m = \frac{y_2-y_1}{x_2-x_1}

Which gives

m = \frac{1-4}{5-0}

m = \frac{-3}{5}

m = -\frac{3}{5}

The line equation is then calculated using:

y -y_1 = m(x - x_1)

Substitute values for m, x1 and y1

y - 4 = -\frac{3}{5}(x - 0)

y - 4 = -\frac{3}{5}(x)

Open bracket

y - 4 = -\frac{3}{5}x

Make y the subject

y  = -\frac{3}{5}x+4

Divide 735 in the ratio 3:2
Irina18 [472]
First add the 2 numbers in the ratio:

3+2 = 5

divide the 735 by 5:

735 / 5 = 147

now multiply 147 by 3 and then by 2 and that will be the ratios:

147 * 3 = 441

147 * 2 = 294
