What is the volume of the plastic rocket???

Mathematics
1 answer:
Marina86 [1]3 years ago
5 0

Answer:

151 in^3

Step-by-step explanation:

The rocket consists of two shapes - a cone and a cylinder

the volume of the plastic = volume of cone + volume of cylinder

volume of a cylinder = nr^2h

Volume of a cone 1/3(nr^2h)

n = 22/7  

r = radius

the diameter is the straight line that passes through the center of a circle and touches the two edges of the circle.

A radius is half of the diameter

Radius = 5/2 = 2.5

Height of cone = 11 - 6 = 5

Volume of plastic = (22/7) x (2/5^2) x 6  + (1/3) x (22/7) x (2/5^2) x 5 = 117.9 + 32.7 = 150.6 in^3 = 151

Answer:

\dfrac{5}{8} butter was left after she was done baking.

Step-by-step explanation:

Robin had 7/8 pound of butter when she started baking a cake. She used 1/4 pound of butter while baking.

We need to find how much butter was left after she was done baking.

It can be calculated as follows,

Left =

=\dfrac{7}{8}-\dfrac{1}{4}\\\\=\dfrac{7}{8}-\dfrac{2}{8}\\\\=\dfrac{7-2}{8}\\\\=\dfrac{5}{8}

Hence, \dfrac{5}{8} butter was left after she was done baking

Simplify (x + 5)2 using the square of a binomial formula.
Olegator [25]

Answer:

x^2 + 10x + 25

Step-by-step explanation:

Hello!

Formula: (a +b)^2 = a^2 + 2ab + b^2

  • a = x
  • b = 5

Plug it into the formula and simplify.

<h3>Simplify</h3>
  • (a +b)^2 = a^2 + 2ab + b^2
  • (x +5)^2 = x^2 + 2(x)(5) + 5^2
  • (x +5)^2 = x^2 + 10x + 25

The answer is the first option: x^2 + 10x + 25.

anastassius [24]

Answer:

The probability is an Empirical Probability

Step-by-step explanation:

The empirical probability (also know as relative frequency, or experimental probability) is the type of probability that involves the ratio of the number of outcomes in which a certain occurrence or event happens to the total number of trials, not in a theoretical sample space but in an actual experiment.

It uses the number of occurrences of an outcome within a sample set as a basis for determining the probability of that outcome.
