Intersecting: y = 8x + 10, y = -1/8x + 10 (f, g)
Parallel: x + y = 5, 7x + 7y = 14 (eq2, eq3); y = 2x + 8, -y = -2x + 6 (p, eq4)
Perpendicular: y = 8x + 10, y = -1/8x + 10 (q, r); 4x + 10y = 6, y = 5/2x + 7 (eq1, h).

Simon says that to find the area of a trapezoid, you can multiply the height by the top base and the height by the bottom base. Then add the two products together and divide the sum by 2. Is Simon correct? Complete the explanation.
Answers
Answer:
Yes, Simon is correct.
Step-by-step explanation:
A trapezoid refers to a quadrilateral that is convex in shape; as such it has no equal sides and no parallel sides.
Let the height of a trapezoid be h.
Let the top base of a trapezoid be b1.
Let the bottom base of a trapezoid be b2.
[tex] Area \; of \; trapezoid = \frac {1}{2} * (Sum \; of \; nonparallel \; sides) * height [/tex]
Therefore, [tex] Area \; of \; trapezoid = \frac {1}{2} * (b_{1} + b_{2}) * h [/tex]
[tex] Area \; of \; trapezoid = \frac {1}{2} * (b_{1}h + b_{2}h) [/tex]
[tex] Area \; of \; trapezoid = \frac {b_{1}h + b_{2}h}{2} [/tex]
Hence, to find the area of a trapezoid, you will multiply the height by the top base and the height by the bottom base. Then you add the two products together and divide the sum by 2.

b. Mills works as a construction worker. He makes a salary of 54,200 a year. After
this year his boss decided to give him a 3.5% raise. What is his new salary?
Answers
Answer:
$56,097
Step-by-step explanation:
First, we have to figure out how much his raise was, so we can convert 3.5% directly to a decimal:
3.5% = 0.035
Then we find
3.5% of 54,200 = 0.035 x 54,200 = 1,897
1,897 + 54,200 = 56,097
So, Mills new salary is $56,097

The Blackburn family has a square field where they keep their cattle. The area of the field is 40,000 ft2, and Mr. Blackburn wants to put a fence diagonally through the field. What should the length of the fence be? *
282.8 feet
4,000 feet
782.6 feet
8,000 feet
Answers
Length of the fence will be = 282.84 feet
Step-by-step explanation:
The Blackburn family has a square field to keep their cattle. Area of the field is $40000 square feet.
Then one side of the square field will be = √Area = √40000 = 200 feet
Since diagonal of a square is = √2(side)² = side√2 = 200√2 = 200×1.41 = 282.84 feet.
Therefore length of the fence will be = 282.84 ft.

The weights in pounds of 6 members of a basketball team are 125, 136, 150, 119,
and 143. Find the mean and the median *
Answers
Answer:
Mean:(137.2)
Median:(139.5)
Step-by-step explanation:
Mean = (125+136+150+119+143) divide by six(6)
= 823/6 = approx 137.2
Median = for the median, you will arrange the numbers in other. from smaller to the bigger number.
119,125,136,143,150, 150. so 136 & 143 is the middle number.
so you will add the middle number and divide by 2.
that is 136+143/2 = 139.5.

An angle θ on the unit circle has a sine of 14. What is the value of cosθ?
Answers
Given:
An angle θ on the unit circle has a sine of [tex]\dfrac{1}{4}[/tex].
To find:
The value of cosθ.
Solution:
We have,
[tex]\sin \theta=\dfrac{1}{4}[/tex]
Since sinθ is positive, therefore, θ lies in first or second quadrant.
We know that,
[tex]\sin^2 \theta +\cos^2 \theta =1[/tex]
[tex](\dfrac{1}{4})^2+\cos^2 \theta =1[/tex]
[tex]\dfrac{1}{16}+\cos^2 \theta =1[/tex]
[tex]\cos^2 \theta =1-\dfrac{1}{16}[/tex]
Taking square root on both sides.
[tex]\cos \theta =\pm \sqrt{\dfrac{16-1}{16}}[/tex]
[tex]\cos \theta =\pm \dfrac{\sqrt{15}}{4}[/tex]
Therefore, the value of cosθ is either [tex]\dfrac{\sqrt{15}}{4}[/tex] or [tex]-\dfrac{\sqrt{15}}{4}[/tex].

How to make a simplified expression for 4(y + 3) - 5

4y + 7
Step-by-step explanation:
Simplify. Use the distribution method, and follow PEMDAS.
PEMDAS is the order of operation. It stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
Distribute 4 to all terms within the parenthesis. In this case, you are multiplying 4 to all the terms:
4(y + 3) = (4 * y) + (4 * 3) = 4y + 12
Next, combine like terms (terms with the same amount of variables);
4y + 12 - 5
4y + (12 - 5)
4y + 7
4y + 7 is your simplified expression.
