Answer:

Both m^2 and cm^2 are given below. Take your pick.

Step-by-step explanation:

Area = L * W

L = 1.57 m * 100 cm / 1 meter = 157 cm

W = 45 cm

Area = 157 cm * 45 cm = 7065 cm^2

In meters, the width would be 45 cm * 1 m / 100 cm = 0.45 m

Area = L * W

L = 1.57 m

W = 0.45 M

Area = 1.57 * 0.45

Area = 0.7065 m^2

$\displaystyle V=16500\ m^3$

Step-by-step explanation:

Volume Of A Pyramid

The volume of a pyramid is computed as one third of the product of the area of the base (B) by the height (H):

$\displaystyle V=\frac{1}{3}BH$

The question doesn't ask for anything in particular, so I'm computing the volume of the solid shown in the image

We have a rectangular base of dimensions 15m x 60 m. The area of the base is

$B=(15m)(60m)=900m^2$

We now calculate the volume, knowing the height is 55 m

$\displaystyle V=\frac{1}{3}(900\ m^2)(55\ m)$

$\boxed{\displaystyle V=16500\ m^3}$

We are drawing two cards without replacement from a standard 52-card deck. find the probability that we draw at least one red c

alina1380 [7]

The probability of drawing only one red card in two draws without replacement is given by:
$P(1\ red)=\frac{26C1\times26C1}{52C2}=0.51$
The probability of drawing two red cards in two draws without replacement isgiven by:
$P(2\ red)=\frac{26C2\times26C0}{52C2}=0.245$
The events 'draw one red card' and 'draw two red cards' are mutually exclusive. Therefore the probability of drawing at least one red card is 0.51 + 0.245 = 0.755.

“Genetic power is far more potent than atomic power. And it will be in everyone's hands. It will be in kits for backyard gardene

steposvetlana [31]

Even though this is not maths, let me help you. In order to answer the first question I suggest you to try to imagine what would happen if people had the power to genetically alter things. It might be helpful to think about how it would affect your life. In that case you would come up to the answer on what should I do with my genetic power.
Now for the second one, let me say that science cannot answer because results are not in the hands of the scientists, but in the hands of the people.
I hope this info can help

A large concrete mixing machine can mix a certain amount of concede in 12 hours, while a smallet one can mix

Andrews [41]

Answer:

[(1/12)(5/5) + (1/20)(3/3)](x hours) = 1

(5/60 + 3/60)x = 1

(8/60)x = 1 we can reduce 8/60 by dividing out a 4

(2/15)x = 1 x both sides by 15/2

x = 15/2

x = 7 1/2 or 7.5 hours
