would you use the same cubic units to meusure the volume of a zoo size aquarium as you would for a box of books

1 answer:

Measurements for solids and liquids are different. If you measure the volume of animals inside the aquarium you could use the same, however ounces and fluid ounces are two different measuring units.

If you think of cooking, chefs use dry measuring cups and liquid measuring cups and spoons to measure ingredients.

(4,-2) and (24,-17) finding the slope from points

Romashka [77]

Use the equation for the slope:
$slope = \frac{y2-y1}{x2-x1}$
The two points are equal to (x1, y1) and (x2, y2).

So choose one of your points to be (x1, y1). Let's choose (4, -2). That means x1 = 4 and y1 = -2.
The other point would then be (x2, y2). So x2 = 24 and y2 = -17.

Now put these values in to the equation:
$Slope = \frac{-17-(-2)}{24-4} = \frac{-15}{20} = \frac{-3}{4}$

The slope is -3/4.

Bob and sarah need to paint a fence. bob can paint the fence in 4 hours and sarah can paint the fence in 2.5 hours. if they work

zysi [14]

If Bob can paint the fence in 4 hours, then in 1 hour he gets 1/4 of the fence painted. If Sarah can paint the fence in 2.5 hours, then she gets 2/5 of the fence painted in one hour (1/2.5 = 2/5). We add those amounts together and set them equal to 1/x, x being the the total time it will take them to paint the whole fence. 1/4 + 2/5 = 1/x. Find a common denominator first, then add the left side together. 5/20 + 8/20 = 1/x. 13/20 = 1/x. Cross-multiply to get 13x = 20 and x = 1.54 hours, just a bit over an hour and a half.

Lubov Fominskaja [6]

Answer:

The answer is "0.6227 and 0.5971".

Step-by-step explanation:

$\to p(x\leq 2)=p(0)+p(1)+p(2)$

$=e^{-2.2}(1+2.2^{1}+\frac{2.2^2}{2!})\\\\=0.6227$

$\to x \sim emp(\frac{1}{2.2})\\\\\to f(x)=\frac{1}{2.2} emp1-\frac{x}{2.2}$

$\to p(x \leq 2)=\int^{2}_{0} \frac{1}{2.2} emp1(-\frac{x}{2.2}\ dx$

$=1-emp1-2|2.2\\\\=0.5971$

What is the slope of the line that is perpendicular to the given line x-2y=10?

laiz [17]

Not sure how to do it in this form but in slope intercept form for example if the slope was -4/3 the perpendicular would be 3/4 it’s the negative reciprocal of the answer
