Answer:

0.743 m

Step-by-step explanation:

Given that :

Volume of cubical tank = 410 L

Volume of a cube = L³

First we convert 410 L into meter cube

1 L = 10^-3 m³

1L = 0.001 m³

410 L = (410 * 0.001) m³

410 L = 0.410 m³

0.410 = l^3

Cube root of both sides

(0.410)^1/3 = l

0.7428958 = l

l = 0.7428958 m

Hence, smallest possible inside length of the cube would be : 0.743m

What is the standard form equation of the line shown below? Graph of a line going through negative 2, 3 and 1, negative 3
V125BC [204]

Answer:

3. 2x + y = −1

Step-by-step explanation:

To find the equation of the line, we write it first in the slope-intercept form:

y=mx+q

where

m is the slope

q is the y-intercept

From the graph, we see that the line crosses the y-axis at y = -1, so the y-intercept is -1:

q=-1

Now we have to find the slope, by calculating the rate of change of the line through 2 points:

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

Taking the two points at (-2,3) and (1,-3), we find:

m=\frac{-3-3}{1-(-2)}=\frac{-6}{3}=-2

So the equation of the line is

y=-2x-1

Now we have to re-arrange it in the standard form, so in the form

ax+bx=c

where a, b and c are integer numbers.

To do that, we simply add +2x on both sides of the equation of the line in the slope-intercept form, and we get:

y+2x=-1

So, option 3).

by selling a mobile set of rupees 4800 Ramesh gains 25% how much will have we gained by selling it at rupees 4080​
Crank

Answer:

240

Step-by-step explanation:

Gain=25%

Gain=selling price - cost price

Gain = ((selling price - cost price )× 100)/ cost price

25c=(4800-c)100

25c=480000-100c

125c=480000

cost price = 3840

second statement

The selling price was 4080

Cost price 3840

therefore

Gain=selling price - cost price

Gain = 4080-3840

=240

Frieda is 67 inches tall and weighs 135 pounds. women her age have a mean height of 65 inches with a standard deviation of 2.5 i
blsea [12.9K]
<span>Frieda's weight is 1 Standard Deviation above the meanwhile her height is less than 1 Standard Deviation away from the mean. This means her height is closer to the mean than her weight.
As a result, we would say that her weight is definitely more unusual than her height because her weight is more standard deviations away from the mean.

Therefore,
</span><span>in relative terms, it is correct to say that:</span> Frieda's height is more unusual than her weight.
