What is 3√45 + 2√ 80−−

This is about angles. Please answer someone?

NISA [10]

Actually, this is not about angles. It's about the length of the sides in a right triangle.

In EVERY right triangle, the squares of the lengths of the short sides add up
to the square of the length of the longest side. You're in high school math,so
I'm SURE you've heard that in class before ... possibly even just before you
were assigned this problem.

Let's say that again: The squares of the lengths of the sides that meet at
the right angle add up to the square of the length of the longest side. In
the triangle in this particular problem, that means
a² + b² = c²

You know the lengths of 'b' and 'c', so you shouldn't have any trouble finding
the length of 'a'.

The cube shaped box is 6 inches wide and the rectangular box is 10 inches long 4 inches wide and 4 inches high. How much greater

nasty-shy [4]

Answer:

Formula of the volume for a cube= s^3 (side, length, width, or edge is acceptable for s)

Formula of the volume for a rectangular prism= lwh (length*width*height)

= 50 cubic in. more

Step-by-step explanation:

cube: 6^3

6x6x6

36x6

216

rectangular prism: 10x4x4

10x16

160

cube - rectangular prism= Difference between cube and rectangular prism

216 - 160 = 50

*REMEMBER that when dealing with volume the units are cubic (whatever), in this case, its cubic inches(in^3).

Please help stattttttttttttttttttt

Fish tank A
V = Ah = 25 ft^2 * 8 ft = 200 ft^3

Fish tank B
V = Ah = 40 ft^2 * 4 ft = 160 ft^3

The volume of fish tank A is 200 ft^3, and the volume of fish tank B is 160 ft^3, so fish tank A has a greater volume. Its volume is greater by 40 ft^3.

Select the instances in which the variable described is binomial.1) A coin flip has two outcomes: heads or tails. The probabilit

Dmitriy789 [7]

Answer: 2) A quality check on a particular product must meet five guidelines. All products are made in the same factory under the same conditions. The random variable represents the total number of products out of 35 tested that pass inspection.

• 3) There are two choices of burritos at a restaurant, vegetarian or beef. The random variable represents the total number out of 254 customers who ordered beef.

• 4) Based on the parents' genetics, each of 6 children from a particular pair of parents has a 0.30 probability of having blue eyes. The random variable represents the total number of children from this pair of parents with blue eyes

Step-by-step explanation:

The binomial distribution simply means the probability of success or failure in an experiment. The instances in which the variable described is binomial are given below:

• 2) A quality check on a particular product must meet five guidelines. All products are made in the same factory under the same conditions. The random variable represents the total number of products out of 35 tested that pass inspection.

• 3) There are two choices of burritos at a restaurant, vegetarian or beef. The random variable represents the total number out of 254 customers who ordered beef.

• 4) Based on the parents' genetics, each of 6 children from a particular pair of parents has a 0.30 probability of having blue eyes. The random variable represents the total number of children from this pair of parents with blue eyes.

Option 1 isn't binomial since the number of trails that are given isn't fixed. Option 5 isn't binomial as well

Therefore, the correct options are 2,3 and 4.
