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]
Side note: the "or" means we pick one region or the other, but not both regions at the same time.

Answer:
width = 40 cm
Step-by-step explanation:
Since the pentagons are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{4x}{x}[/tex] = [tex]\frac{48}{x+2}[/tex] ( cross- multiply )
4x(x + 2) = 48x ← distribute left side
4x² + 8x = 48x ( subtract 48x from both sides )
4x² - 40x = 0 ← factor out 4x from each term on left side
4x(x - 10) = 0
Equate each factor to zero and solve for x
4x = 0 ⇒ x = 0
x - 10 = 0 ⇒ x = 10
However, x > 0 then x = 10
Thus width = 4x = 4 × 10 = 40 cm

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.

Step-by-step explanation:
If you do $120/8 dolls you get $15 for each doll at Walmart. If you do $102/6 dolls you get $17 for each doll. You know $15 is less than $17 making it cheaper and a better deal. Target's dolls are $2 more than Walmart. $17-$15=$2

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.

How much of an alloy that is 10% copper should be mixed with 600 ounce of an alloy that is 70%copper in order to get an alloy that is 30%copper?
Answer:
1200 ounces
Step-by-step explanation:
How much of an alloy that is 10% copper should be mixed with 600 ounce of an alloy that is 70%copper in order to get an alloy that is 30%copper?
Let us represent
Number of ounce of 10% copper = x
Hence, our Equation =
x × 10% + 600 × 70% = (x + 600) × 30%
0.1x + 420 = (x + 600)0.3
0.1x + 420 = 0.3x + 180
Collect like terms
0.3x - 0.1x = 420 - 180
0.2x = 240
x = 240/0.2
x = 1200 ounces

You and your cousin go out to eat and you both have the same taste today and order the same item. You both order the $9 item and both have a $2.50 side item. You receive 50% off your entire bill! You then pay 10% tax on your new discounted bill. What does the bill end up costing you without tip?
The bill is $12.65 without a tip.
Answer:
$12.65
Step-by-step explanation:
The total of just you and your cousin's meals would be $23. Then taking 50% off would be $11.50. Lastly, with the 10% tax, that would make it $12.65. Sorry if I get it wrong.

Blake bought a new car. He borrowed $12,500 from the bank. After 4 years he had paid off the loan and paid $1500 in interest. What rate did he borrow at? Include the steps you used to solve the problem and your answer
Answer:
3%
Step-by-step explanation:
Blake bought a new car. He borrowed $12,500 from the bank. After 4 years he had paid off the loan and paid $1500 in interest. What rate did he borrow at?
This is a simple interest question
The formula to find the rate is given as:
Equation:
r = (1/t)(A/P - 1)
t = time = 4 years
P = Principal = $12500
I = Simple Interest = $1500
A = Total Amount = Principal + Simple Interest = $12500 + $1500
= $14000
Calculation:
Solving our equation:
r = (1/4)((14000/12500) - 1) = 0.03
r = 0.03
Converting r decimal to R a percentage
R = 0.03 * 100 = 3%/year

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.
o
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
