Step-by-step explanation:
The Pythagorean theorem states that the sum of the squares of the legs of a right triangle is equal to the square of the
hypotenuse by the formula a? + b2 = -2
If a is a rational number and b is a rational number, why could c be an irrational number?
Answer:
For the value of hypotenuse can be irrational, sum of squares of other two legs might be imperfect square number.
Step-by-step explanation:
We all know, the Pythagorean theorem can be stated as follows:
The sum of squares of two legs of a right angled triangle is equal to the square of the hypotenuse.
i.e.
[tex]a^2+b^2=c^2[/tex]
Where, [tex]c[/tex] is the hypotenuse and [tex]a, b[/tex] are the two other legs of the right angled triangle.
Given that:
[tex]a[/tex] and [tex]b[/tex] are rational numbers.
To find:
Situation for which [tex]c[/tex] is irrational.
Square of a rational number is always rational.
So, [tex]a^{2} , b^{2}[/tex] both will be rational.
And sum of squares of two rational numbers will also be rational.
Therefore, [tex]a^2+b^2[/tex] will also be rational.
and
[tex]c = \sqrt{a^2+b^2}[/tex]
For the value of [tex]c[/tex] can be irrational, sum of squares of other two legs might be imperfect square number.
You use substitution to solve a system of equations and, after simplifying, end with a statement that says 7 = 7. Describe what this statement means about the number of solutions and about the graph of the system. .

The measure of angle 1 is 3k - 7 and the measure of angle 8 is 5k + 29 29. What is the value of k
A: k= -18
B: k= 19.75
C: k= 36
D: k= 72
Answer:
Its A k = -18
Step-by-step explanation:
Because since angle 1 and 8 are the same your equation is 3k-7 = 5k+29. and then you solve and get k = -18.

An egg carton holds 12 eggs. A breakfast buffet uses 96 eggs by
8 A.M. When the buffet ends at 10:30 A.M., a total of 156 eggs were
used. How many cartons
of eggs were used after 8 A.M.?
Answer:
13 Cartoons
Step-by-step explanation:
As, in 1 cartoon = 12 eggs
x cartoon = 156
X = 156 / 12
X = 13
Therefore, 13 Cartoons were used after 10:30 am

Regina spent $45.50 over 612 months on music downloads.
If she spent the same amount of money each month, how much money did Regina spend per month on music downloads?
Answer:
.07 cents
Step-by-step explanation:
In order to solve this question all you need to do is divide the money spent by the amount of months. 45.50/612=0.0743464052 but since you cant spend .0043464052 of a cent we have to change the answer to .07. To check our answer is right all we need to do is multiply 0.0743464052 by 612=45.499999 so we know the answer is correct.

Find the equation of the line that is perpendicular to the given line and passes through the given point. Enter your answer in slope-intercept form (y=mx+b) with the values of m and b given as decimals, rounded to the nearest hundredth if necessary.
y=2x;(9,-4)
The equation is y=
Answer:
y = -1/2x + 1/2
Step-by-step explanation:
perpendicular lines have slopes that are opposite signs and reciprocal
therefore, use m=-1/2 and point (9, -4) to complete the equation by finding 'b' (the y-intercept)
-4 = -1/2(9) + b
-4 = -9/2 + b
-4 + 9/2 = b
-4 + 4 [tex]\frac{1}{2}[/tex] = b
b = [tex]\frac{1}{2}[/tex]

During a flood, James used two pumps to get the water out of his
basement. The big pump moves 3 gallons of water per minute. The
small pump moves 4 gallons in 5 minutes. How many more gallons
does the big pump move than the small pump after 10 minutes?
Answer:
The big pump moves 22 more gallons in 10mins
Step-by-step explanation:
The total the big pump moves is 30 gallons in 10mins because 3x10 = 30
The small pump moves 8 gallons in 10mins becuase 4x2= 8
Its asking for how many more so 30 - 8 = 22 More gallons
16, 3x + 2y = 8 5x+ 2y = 12 What is the solution of the system of equations shown above? A(-2,7) B. (2,1)
C.4/3,2
D
2,4
Answer:
The solution of the system of the equations is (2, 1) ⇒ B
Step-by-step explanation:
Let us solve the system of equations
∵ 3x + 2y = 8 ⇒ (1)
∵ 5x + 2y = 12 ⇒ (2)
→ Subtract equation (1) from equation (2)
∴ (5x - 3x) + (2y - 2y) = (12 - 8)
∴ 2x + 0 = 4
∴ 2x = 4
→ Divide both sides by 2
∴ x = 2
→ Substitute the value of x in equation (1) or (2) to find y
∵ 3(2) + 2y = 8
∴ 6 + 2y = 8
→ Subtract 6 from both sides
∵ 6 - 6 + 2y = 8 - 6
∴ 2y = 2
→ Divide both sides by 2 to find y
∴ y = 1
∴ The solution of the system of the equations is (2, 1)
factor and then solve the question.

Five aluminum cans can be recycled to make a new can. How many new cans can eventually be made from 125 aluminum cans
Answer:
25 new cans
Step-by-step explanation:
Given that:
Number of aluminum cans needed to make a new can = 5
total number of aluminum cans = 125
Number of new cans that can be made :
Total number of aluminum cans / aluminum cans needed to make a new can
= 125 / 5
= 25 new cans
