Step-by-step explanation:
Answer: Alternate interior angles have the same measure. As we know that 'angle 1 ' and 50° are alternate interior angles hence they must be equal. Also we now that sum of all the angles of a triangle is equal to 180°. Hence, m∠2=15°.

two zero of the 6000 will cancel two zero of 100
6÷700 and 60
140 over 10
5÷140 and 10

Question 3 of 7
A circular garden has a diameter of 10 yards. What is the area of the garden?
Use 3.14 for T.
Answer:
78.5 yards
Step-by-step explanation:
Essentially, to find the area of a circle simply use the equation pi r^2 (r=radius, or half of diameter). They also make it really easy by saying we may use 3.14 for pi, so really, we simply have to solve:
(3.14)5^2=78.5 yards

describe how to determine if a function is a linear or non-linear from a table
Answer:
To see if a table of values represents a linear function, check to see if there's a constant rate of change. If there is, you're looking at a linear function!

Find RS 2x+15 3x+5 6x-37
Answer:2x+15+6x-37/2=3x+5
We move all terms to the left:
2x+15+6x-37/2-(3x+5)=0
We add all the numbers together, and all the variables
8x-(3x+5)+15-37/2=0
We get rid of parentheses
8x-3x-5+15-37/2=0
We multiply all the terms by the denominator
8x*2-3x*2-37-5*2+15*2=0
We add all the numbers together, and all the variables
8x*2-3x*2-17=0
Wy multiply elements
16x-6x-17=0
We add all the numbers together, and all the variables
10x-17=0
We move all terms containing x to the left, all other terms to the right
10x=17
x=17/10
x=1+7/10
The value of RS is 31.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
If RS and UT are parallel, then their corresponding sides are proportional. Thus,
RS/UT = (2x + 15)/(6x - 37)
Now,
RS/UT = (2x + 15)/(6x - 37)
Cross-multiplying.
(2x + 15)UT = RS(6x - 37)
Expanding and simplifying.
2xUT + 15UT = 6xRS - 37RS
Rearranging.
6xRS - 2xUT = 15UT + 37RS
Factorizing.
2x(3RS - UT) = 15UT + 37RS
Dividing both sides by (3RS - UT):
2x = (15UT + 37RS)/(3RS - UT)
Substituting RS = 2x + 15 and UT = 6x - 37:
2x = (15(6x - 37) + 37(2x + 15))/(3(2x + 15) - (6x - 37))
Simplifying
2x = (90x - 555 + 74x + 555)/(6x + 36)
2x = (164x)/(6x + 36)
Multiplying both sides by (6x + 36):
12x² + 72x = 164x
Simplifying
12x² - 92x = 0
Factoring out 4x.
4x(3x - 23) = 0
So,
x = 0 or x = 23/3.
Since x cannot be 0 (as it would make UT = -37, (which is not possible),
x = 23/3.
Substituting this value of x into RS = 2x + 15.
RS = 2(23/3) + 15 = 31
Thus,
The value of RS is 31.

The outlier would be 28 because it is much lower than the rest of the numbers in the group and removing it would make the mean increase.
how do I determine the lower quartile and the upper quartile
Step-by-step explanation:
the lower quartile is the value of the middle of the first set of numbers, the upper quartile is the middle of the second set.
for example: 2 2 5 (7 )2 0 9
the seven is the median.
upper quartile would be the zero.
and lower quartile would be the second two.

Mr. Clark plans to spend no more than $400 on sandwiches and water for a work meeting. Each case of water costs $7.00 and each sandwich costs $5.00. Which inequality would Mr. Clark use to determine how many sandwiches, s, and how many cases of water, w, he can buy?
Answer:
[tex]7w+5s\leq 400[/tex]
Step-by-step explanation:
Money to be spent is not more than $400.
Cost of a case of water = $7
Cost of each sandwich = $5
Let number of cases of water bought be [tex]w[/tex]
Number of sandwiches bought be [tex]s[/tex]
From the question we get
[tex]7w+5s\leq 400[/tex]
The inequality which would determine how many sandwiches, and how many cases of water that can be bought is [tex]7w+5s\leq 400[/tex].

can someone solve this for me? Its Solving the following system of equations using substitution.
Y = 6X + 5
Y=5X -9
Answer:
X = -14, Y = -79
Step-by-step explanation:
The two equations both equal Y, a constant, so they can be set to each other.
6X + 5 = 5X - 9X = -14Find y by plugging -14 into X in either of the equations.
Y = 5(-14) - 9Y = -79Side note: capitalized variables are generally unpreferred, hope your teacher stops using them! ;)
