A paper air plane looking polygon with sides of 5 5 and 8 what is the area

1 answer:

8 0

If it has 3 sides then it's a triangle.
Using the formula $A= \sqrt{s(s-a)(s-b)(s-c)}$
where $s= \frac{a+b+c}{2}$
and a=5 b=5 c=8

∴ $s= \frac{5+5+8}{2} =9$
$area= \sqrt{9(9-5)(9-5)(9-8)}$
$area= \sqrt{144} = 12units^{2}$

Which situation shows a constant rate of change? A. The number of points scored in a basketball game compared with the number of

bezimeni [28]

Answer: D

Step-by-step explanation:

A constant rate of change means that for every x, y increases the same amount.

In the situation "The amount a person pays for gas compared with the number of gallons purchased ," the independent quantity, or x-value, is the number of gallons, and the dependent quantity, or y-value, is the amount paid. Since gas has a set price per gallon, for every gallon purchased, the total amount paid goes up the same amount. This means it has a constant rate of change.

three zebras are chilling in the desert. suddenly a lion attacks. each zebra is sitting on a corner of an equally length triangl

AnnyKZ [126]

Probability that no zebras collide is 0.25

The zebras are represented as z1, z2 and z3.

Z1 to B, Z2 to C, and Z3 to A come first $= (\frac{1}{2})^3$

Following that, z1 to C, z2 to A, and z3 to B = $(\frac{1}{2})^3$

Consequently, the likelihood of no collision is 2×1/8 = 0.25.

<h3>What are the types of probability distributions ?</h3>

Discrete and continuous probability distributions are the two main categories in which probability distributions fall. There are numerous varieties of probability distributions within each category.

The number of favorable outcomes of an event divided by the total number of possible outcomes of an event can be used to calculate the probability of an event.
The likelihood of a sure or certain event is one.
The likelihood of an impossibility is 0 (0).
Every event has a probability between 0 and 1.

write a word problem that can be solved using a system of two linear equations. solve the problem and give the meaning of the an

dmitriy555 [2]

Answer:

The sum of two numbers is 25. One of the numbers exceeds the other by 9. Find numbers

the other number = x + 9

Let the number be x.

Sum of two numbers = 25

According to question, x + x + 9 = 25

⇒ 2x + 9 = 25

⇒ 2x = 25 - 9

⇒ 2x = 16

⇒ 2x/2 = 16/2

⇒ x = 8

Therefore, x + 9 = 8 + 9 = 17

Therefore, the two numbers are 8 and 17.
