Putting the values in the formula,
We get,
= 2 [ (80 x 30) + (30 x 30) + (30 x 80)]
= 2 (2400 + 900 + 2400)

Which numbers belong to the solution set of the inequality? x+6= 42
Answers
Answer:
36
Step-by-step explanation:
Answer:
x=36 is your answer
Step-by-step explanation:
Simplifying
x + 6 = 42
Reorder the terms:
6 + x = 42
Solving
6 + x = 42
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6' to each side of the equation.
6 + -6 + x = 42 + -6
Combine like terms: 6 + -6 = 0
0 + x = 42 + -6
x = 42 + -6
Combine like terms: 42 + -6 = 36
x = 36
Simplifying
x = 36
g Suppose a kind of disease exists within 1% of the population and a certain test can help diagnose it. If someone has the disease, the test will give a positive result with a 95% probability. On the other hand, if someone does not have the disease, the test result will give a negative result 97% of the time. If David did the test once, what is the probability that the test result is positive
Answers
Answer:
0.0392 = 3.92% probability that the test result is positive.
Step-by-step explanation:
Probability of a positive test:
95% of 1%(person has the disease)
100 - 97 = 3% of 100 - 1 = 99%(person does not have the disease).
What is the probability that the test result is positive?
[tex]p = 0.95*0.01 + 0.03*0.99 = 0.0392[/tex]
0.0392 = 3.92% probability that the test result is positive.

The value of a from the given triangle is [tex]5\frac{1}{3}[/tex] units. Therefore, option B is the correct answer.
What is the Pythagoras theorem?The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.
From the triangle we have WX=b, WZ=c, ZY=3, YX=a and WY=4.
By Pythagoras theorem,
c²=4²+3²
c²=16+9
c²=25
c=5 units
In triangle WXZ,
(3+a)²=5²+b² ----(i)
From the triangle WXY,
b²=4²+a² ------(ii)
From equation (i) and (ii), we get
(3+a)²=5²+4²+a²
9+6a+a²=41+a²
6a=32
a=32/6
a=[tex]5\frac{1}{3}[/tex] units
Therefore, option B is the correct answer.

Hi there!
[tex]\large\boxed{x = -9, 0}[/tex]
Find the zeros using factoring:
f(x) = x³ + 9x²
Factor out the common term, or x²:
f(x) = x²(x + 9)
Set each factor equal to 0:
x² = 0
x = 0
x + 9 = 0
x = -9
The zeroes are -9, 0.

Tell whether the ordered pair (-1,3) is a solution of the system of linear equations. y=-7x-4 and y=8x+5
Answers
Answer:
Since it does not plug in to the second linear equation, the ordered pair is not a solution of the linear system.

(-1,3); y = -7x -4 y = 8x + 5 3 =7 - 4 3 =/ - 8 + 5
For a system of equations to have no real solution, the lines of the equations must be parallel to each other. The ordered pair (-1,3) is not the solution of the given system of equations.
What is the System of equations?Inconsistent SystemFor a system of equations to have no real solution, the lines of the equations must be parallel to each other.
Consistent System
1. Dependent Consistent System
For a system of the equation to be a Dependent Consistent System, the system must have multiple solutions for which the lines of the equation must be coinciding.
2. Independent Consistent System
For a system of the equation to be an Independent Consistent System the system must have one unique solution for which the lines of the equation must intersect at a particular.
The solution of the equation can be found by plotting the equation on the graph. Therefore, the point at which the equation will intersect will the solution of the system of equation.
Since the solution of the system of equation is (-0.6, 0.2), there exists only one single solution for the system of equation. therefore, the (-1,3) is not the solution of the system of equation.
Hence, the ordered pair (-1,3) is not the solution of the given system of equations.
