Gilligan sees a ship coming close to the shore he's standing on. He wants to
determine the distance (SD) from the ship to the shore. He walks 130 ft along the
shore from point D to point C and marks that spot. Then he walks 23 ft further and
marks point B. He turns 90 and walks until his location (point A), point C, and point
S are collinear.

Answer the following questions making sure to show all your work.
(a) Can Gilligan conclude that triangle ABC and triangle SDC are similar? Why or why
not?
(b) Suppose AB = 90 ft. What can Gilligan conclude about the distance of the ship
from the shore? Explain.
The triangles ABC and SDC are similar triangles
Gilligan can conclude that triangles ABC and SDC are similarGilligan can conclude that the distance of the ship from the shore is 509 ftHow to determine if the triangles are similarFrom the question, we understand points S, C and A are collinear, while line AB and SD are vertical and parallel lines at the either sides of point C.
Hence, Gilligan can conclude that triangles ABC and SDC are similar
How to calculate the distance SD
To do this, we make use of the following equivalent ratio
[tex]SD : 130 = AB : 23[/tex]
Substitute 90 for AB
[tex]SD : 130 =90 : 23[/tex]
Express as fraction
[tex]\frac{SD}{130} =\frac{90}{ 23}[/tex]
Make SD the subject
[tex]SD =\frac{90}{ 23} * 130[/tex]
[tex]SD =509[/tex]
Hence, Gilligan can conclude that the distance of the ship from the shore is 509 ft

Which compound inequality is represented by the graph?
(A.) -2
(B.) -2_
(C.) x<-2 or x_>4
(D.) x_<-2 or x>4
Answer: Choice C
[tex]x < -2 \ \text{ or } \ x \ge 4[/tex]
========================================================
Explanation:
The blue portion on the left is represented by [tex]x < -2[/tex] as it describes values smaller than -2. Notice the open hole at -2 which indicates we do not include this value. So that's why we go with [tex]x < -2[/tex] instead of [tex]x \le -2[/tex]
The blue portion on the right is represented as [tex]x \ge 4[/tex] describing values that are equal to 4, or larger than 4.
So overall, the entire graph visually represents x values such that [tex]x < -2 \ \text{ or } \ x \ge 4[/tex]

Sum of the angles of a triangle = 180degrees
Combine like terms
Add 41 to both sides
Divide both sides by 41
Substitute x = 13 to find m angle p
6x - 23 + 3x -1 + 8x -17 = 180
17x - 41 = 180
17x = 221

Stilton is paying for a $25 meal. He has a 15%-off coupon for the meal. After the discount, a 7% sales tax is applied
Answer:
$19.76
Step-by-step explanation:
First you turn the 15% to 0.15 and then you multiply it with $25 to get 3.75.
That isn't the meal though, but the discount you are going to get.
Now subtract 3.75 from 25 to get $21.25
After that multiply 21.25 with 7% which gets you 1.4875
Then, subtract 1.4875 from 21.25 to get 19.7625 which is rounded to $19.76

There were 128 children signed up for baseball camp. If each team is made up of 12
children, how many teams will there be and how many children are left over?
Answer:
There will be 10 teams and 8 children left over.
Step-by-step explanation:
12 * 10 = 120. This is the closest you can get to 128 without going over, so that means there will be 10 teams of 12 children. 128 - 120 = 8. Therefore, there are 8 children left over.
Answer: There will be 10 teams with 8 kids left over.

Denna has 80 books in her collection now. If 60% of the books are fiction,how many of the books are nonfiction?
Answer:
32 books are none fiction.
Step-by-step explanation:
If %60 of her books are fiction that means that 40% are nonfiction (since in total there are 100% books and 60% are fiction which means that the rest is non-fiction). In order to find 40%, we just multiply the total amount of books by 0.4, and so we get...
80 x 0.4 = 32
Therefore 32 books are none fiction.

Answer: B.) vertex
Step-by-step explanation:
On a parabola, the extreme point (which is the highest, lowest, or farthest point left or right) is called the ''Vertex.''
What is Coordinates?A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.
Given that;
To find the extreme point of the parabola.
Now, We know that;
Every parabola has a shape of an U,
Then, they have an extreme point. Depending if the parabola has the formula y = ax² + bx + c or x = ay² + by + c (where a, b and c are constants) and what value constant a has, what kind of extreme point the parabola have.
Hence, On a parabola, the extreme point (which is the highest, lowest, or farthest point left or right) is called the ''Vertex.''

Loris has one of each of the following colours of felt-tip pen in her pencil case:
red (R) blue (B) yellow (Y) green (G) purple (P)
She pulls out two random pens.
How many different combinations of pairs of colours are there?
there are 10 different combinations of pairs of colors.
What is the combination?Combinations are ways to choose elements from a collection in mathematics where the order of the selection is irrelevant. Let's say we have a trio of numbers: P, Q, and R. Then, combination determines how many ways we can choose two numbers from each group.
Given, Loris has one of each of the following colors of felt-tip pen in her pencil case: red (R) blue (B) yellow (Y) green (G) purple (P) She pulls out two random pens.
from the formula of combination;
total combination ⁿCₓ = [tex]\frac{n!}{(n-r)! * r!}[/tex]
Where, n = total numbers
r = desired number out of total
In our case
n = 5 and r = 2
Thus, the Total combination = ⁵C₂
Total combination = 5! / (3! *2!)
total combination = 5 *4 /2 = 10
therefore, There are ten distinct ways to pair the colors together.
