A. 8/15
B. 15/8
C. 8/17
D. 15/17
Answer:
C. 8/17
Step-by-step explanation:
Given:
Hypotenuse = 17
BC = 8
Cos (B) = leg adjacent to ∠B / hypotenuse
= BC/BA
Substitute
Cos (B) = 8/17
Hence option C is correct
After six weeks of the coupon offer, the owner of the restaurant needs to decide if the restaurant should continue to run the same special or offer a new one. Use the provided scatter plot to write an equation for the line of best fit.
The equation of the line of the best fit on the scatter plot is y = 150x + 598
How to determine the equation of the line of best fit?From the line in the scatter plot, we have the following points
(x,y) = (3,1048) and (6,1498)
The equation is then calculated using:
[tex]y = \frac{y_2 -y_1}{x_2 -x_1} *(x - x_1) + y_2[/tex]
The equation becomes
[tex]y = \frac{1498 -1048}{6 - 3} *(x - 3) + 1048[/tex]
Evaluate
y = 150 *(x - 3) + 1048
Expand the bracket
y = 150x - 450 + 1048
Evaluate the sum
y = 150x + 598
Hence, the equation of the line of the best fit is y = 150x + 598

OPTIONS:
A) lengths of consecutive sides are not equal
B) slopes of opposite sides are equal
C) lengths of opposite sides are equal
D) slopes of consecutive sides are not equal

In the proof given, BC║AD and CD║BA because: B. slopes of opposite sides are equal.
What is the Slope of Parallel Lines?If two lines are parallel, they will have the same slope value,.
Slope = rise/run.
Slope of BC = rise/run = -2/5
Slope of AD = -2/5
Slope of BA = rise/run = -6/1 = -6
Slope of BA = rise/run = -6/1 = -6
Therefore, we can conclude that BC║AD and CD║BA because: B. slopes of opposite sides are equal.

Sheryl makes $7 per pair of
earrings, e, and $13 per necklace,
n, she sells. What expression
represents her total income?
The expression T = 7e + 13n represents the total income of Sherly where e is the number of earrings she sells and n is the number of necklace she sells.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
We have:
Sheryl makes $7 per a pair of earrings, e, and $13 per necklace, n, she sells.
Let's suppose the total income of Sherly is T:
Then,
T = 7e + 13n
Here e is the number of earrings she sells and n is the number of necklace she sells.
T is the total income and the expression T = 7e + 13n represents the total income of Sherly.
Thus, the expression T = 7e + 13n represents the total income of Sherly where e is the number of earrings she sells and n is the number of necklace she sells.

Answer:
y = (2x/9) + 1
Step-by-step explanation:
Solving for y we get 3(-2y+x) = 5(-3y+x)+9
Expand the above we get -6y+3x=5(-3y+x)+9
which is -6y+3x = -15y+5x+9
then 9y = 2x+9

What is Area of Triangle?
The area of a triangle is defined as the total space occupied by the three sides of a triangle in a 2-dimensional plane. The basic formula for the area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h.
The area of a triangle = (base x height) / 2
and,
both lights illuminate the same base and height = (60 x 38) / 2
= 1,140 sq ft
Both Dylan's and Nikki's proposed placement will lit exactly half of the yard.
The yard's total area = 60 x 38 = 2,280 sq ft,
which is twice the area lit by the lights.
