If a rectangular prism has a length width and height of 3/8 cm 5/8 cm and 7/8 cm then the volume of the prism is ........ cubic

pychu [463]

Answer:

105/512

Step-by-step explanation:

To find the volume of a rectangular prism, you do length x width x height. The length is 3/8, the width is 5/8, and the height.

Multiply or divide the following measurements. Be sure each answer you enter contains the correct number of significant digits.

nydimaria [60]

Answer:

93.4 g/mL x 20. mL = 1868g.

489.7m / 53.061 s = 9.23 m/s

216.3 m/66.4 s = 3.26 m/s.

Step-by-step explanation:

Let's analyze each case.

93.4 g/mL x 20. mL

Hewe we are multiplying g/ml*ml. So we have the answer is (g*ml/ml) = g.

So

93.4 g/mL x 20. mL = 1868g.

489.7m / 53.061 s

We are dividing a measurement in m by a measurement in s. So the answer is in m/s.

So

489.7m / 53.061 s = 9.23 m/s

216.3 m/66.4 s

Same as above.

We are dividing a measurement in m by a measurement in s. So the answer is in m/s.

So

216.3 m/66.4 s = 3.26 m/s.

find the particular solution to the exact differentiable equation dy/dx=(2e^x)-cosx passing through the point (0,3)

lozanna [386]

Answer:

y = 2eˣ - sin x + 1

Step-by-step explanation:

dy/dx = 2eˣ - cos x

(0, 3)

Integrate dy/dx to find the original function.

y = 2eˣ - sin x + C

Solve for C by substituting the point given.

3 = 2e⁰ - sin(0) + C
3 = 2 - 0 + C
1 = C

Now we can substitute C into the original function.

y = 2eˣ - sin x + 1

This is the particular, or explicit, solution to the differentiable equation.

You spent $175 on a pair of shoes and three shirts. Each shirt cost the same amount. The shoes cost four times the amount of one

sergey [27]

Step-by-step explanation:

1. making the equation:

shoes = x

shirts = y

175 = x + 3y

x = 4y

2. graph it (I'm using desmos)

the green line is for 175 = x + 3y and the purple one is for x = 4y

3. find the price

x = 4y

175 = 4y + 3y

175 = 7y

y = 175/7 = $25

price of the shirt = $25

x = 4y = 4*25 = $100

price of a pair of shoes = $100

A box contains 3 coins. One coin has 2 heads and the other two are fair. A coin is chosen at random from the box and flipped. If

Blababa [14]

Answer: Our required probability is $\dfrac{1}{2}$

Step-by-step explanation:

Since we have given that

Number of coins = 3

Number of coin has 2 heads = 1

Number of fair coins = 2

Probability of getting one of the coin among 3 = $\dfrac{1}{3}$

So, Probability of getting head from fair coin = $\dfrac{1}{2}$

Probability of getting head from baised coin = 1

Using "Bayes theorem" we will find the probability that it is the two headed coin is given by

$\dfrac{\dfrac{1}{3}\times 1}{\dfrac{1}{3}\times \dfrac{1}{2}+\dfrac{1}{3}\times \dfrac{1}{2}+\dfrac{1}{3}\times 1}\\\\=\dfrac{\dfrac{1}{3}}{\dfrac{1}{6}+\dfrac{1}{6}+\dfrac{1}{3}}\\\\=\dfrac{\dfrac{1}{3}}{\dfrac{2}{3}}\\\\=\dfrac{1}{2}$

Hence, our required probability is $\dfrac{1}{2}$

No, the answer is not $\dfrac{1}{3}$
