Answer:
75.062c
Step-by-step explanation:
To find the missing side use pythagorean theorem
So
Solve for b, b= 6.021
To find the area use bh
So (6.021+19)(6)= area
And you get 75.062
Answer:
He has 420 liters of paint.
Step-by-step explanation:
all you have to do is add 110 = 310
we know that
A number is an inequality solution if the number satisfies the inequality
<u>Part 1)</u>
rewrite the inequality
The answer Part 1) is the option D
Because satisfies the inequality
-----> is true
<u>Part 2)</u>
The answer Part 2) is the option A
Because satisfies the inequality
-----> is true
<u>Part 3)</u>
we're going to verify every case
<u>case A)</u> For
substitute the value of x in the inequality
------> is true
therefore
The number is a solution
<u>case B)</u> For
substitute the value of x in the inequality
------> is not true
therefore
The number is not a solution
<u>case C)</u> For
substitute the value of x in the inequality
------> is not true
therefore
The number is not a solution
<u>case D)</u> For
substitute the value of x in the inequality
------> is not true
therefore
The number is not a solution
therefore
The answer Part 3) is the option A
4 + 3x = 12
3x = 12 - 4
3x = 8
x = 8/3
x = 2,6 grams
A number is rational if it can be written in form a/b where a and b are integers and b is not equal to 0
integers are like -4,-3,-2,-1,0,1,2,3,4, etc
so
√20=2√5 which is irrational because we can't write it as a fraciton with only integers
also a rational number multilied by an irratinonal number=irrtaional
we know that the square root of any prime number will be irrational and 5 is prime so 2 times √5=rational times irrational=irrational
√20 is irrational
