A spinner is spun twice with 3 equal sections colored orange, red, and purple. What is the P(spinning one Red and one Purple)?
Answer:
P(red) = 1/3
P(purple) = 1/3
P(red, then purple) = (1/3)(1/3) = 1/9
P(purple, then red) = (1/3)(1/3) = 1/9
P(red and purple) = 1/9 + 1/9 = 2/9
A photographer’s darkroom needs a new coat of black paint on all surfaces of the room, including the ceiling and the floor. The room is a cube with edge length 11
feet. How much surface area must be painted?
The surface area of a cube is given by the formula 6s^2, where s is the length of the edge. In this case, s = 11 feet, so the surface area of the cube is:
6s^2 = 6(11)^2 = 6(121) = 726 square feet
Since the room has six surfaces that need to be painted (four walls, one ceiling, and one floor), the total surface area that needs to be painted is:
6 x 726 = 4356 square feet
Therefore, the photographer's darkroom needs to have 4356 square feet of black paint applied to all of its surfaces.

Part A: To draw triangles ABC and DEC separately, follow these steps:
Draw a line segment DE with a length of 1.2 feet. This will be the base of both triangles.At point D, draw a perpendicular line segment DC with a length of 2 feet. This will be the height of triangle DEC.At point E, draw a line segment EB with a length of 0.3 feet. This will be the height of triangle ABC.Connect points C and B with line segment BC. This will be the hypotenuse of both triangles.What is the others about?The lengths of sides BC, DE, and EC are as follows:
BC: It is the hypotenuse of triangle ABC and has a length that needs to be calculated using the Pythagorean theorem.DE: It is the base of both triangles and has a length of 1.2 feet.EC: It is the height of triangle DEC and has a length of 2 feet.Part B: To find side AB of triangle ABC, we can use the concept of similarity and ratios. Since triangles ABC and DEC are similar, their corresponding sides are proportional. We can set up the following proportion:
AB/DE = BC/EC
Plugging in the given values, we get:
AB/1.2 = BC/2
To solve for AB, we can cross-multiply and then divide:
AB = (BC/2) x 1.2
Now we need to find the value of BC. We can use the Pythagorean theorem, as BC is the hypotenuse of triangle ABC. The Pythagorean theorem states that the square of the hypotenuse is equal to the sum of the squares of the other two sides.
BC² = AB² + BE²
Plugging in the given value for BE, we get:
BC^2 = AB² + 0.3²
Now we can substitute the value of AB from the previous equation into this equation:
BC² = ((BC/2) * 1.2)² + 0.3²
Simplifying, we get:
BC² = 0.36 x BC^2/4 + 0.09
Multiplying both sides by 4 to eliminate the fraction, we get:
4 x BC² = 0.36 x BC² + 0.36 + 0.09
Combining like terms, we get:
4 x BC² = 0.36 BC² + 0.45
Subtracting 0.36 x BC² and 0.45 from both sides, we get:
3.64 x BC² = 0.45
Dividing both sides by 3.64 to isolate BC², we get:
BC² = 0.45 / 3.64
Taking the square root of both sides to solve for BC, we get:
BC ≈ √(0.45 / 3.64)
BC ≈ 0.357 feet
Now we can substitute the value of BC back into the equation for AB:
AB = (BC/2) x 1.2
AB ≈ (0.357/2) x 1.2
AB ≈ 0.214 feet
So, the approximate length of side AB of triangle ABC is 0.214 feet.

Both careers help students learn; however, teaching and training careers are involved in running the school.
Both careers are increasing the number of available jobs; however, professional support career earns less money.
Both careers have support careers; however, professional support careers assist in the classroom.
Answer:
Both careers try to support student success; however, teaching and training careers involve direct instruction of students.
Answer Explanation:
Professional support careers help people involved in education and training systems with personal and family needs, educational goals, mental health assistance, and career decision-making. They provide support and encouragement to students undergoing challenging experiences. Professional support career titles include counselors and Psychologists, among others.
Teachers and trainers offer instructions to students in the class or other conducive places. They help students complete their syllabus, learn the intended materials, acquire knowledge, and pass their examinations.

B) After five weeks of his earning, he has to pay 28% in taxes. How much were the
taxes? How much of his total pay does he have left after taxes? Show and explain all
of your work.
ANSWER BOTH QUESTIONS QUESTION A AND QUESTION B.
Answer: A) $333
B) $468
Step-by-step explanation:
A) First we multiply. 130x5=650 Now we know that we have to get $650 total in 5 weeks in order to get an average of $130 per week.
87+105+125=317
650-317=333
Necolai has to earn $333 the fifth week to achieve an average of $130 per week.
B) 28% of 650 = 182
Now subtract the taxes from his earnings. 650-182=468
Necolai has $468 of his total pay after taxes.

Kylie brought 5 pears to soccer practice to share with her teammates. She cuts each pear into thirds. How many slices of pears does she have to share with her teammates? Which equations can you use to solve the problem? Select two equations.
A. 5 × 3 = 15
B. 1/5 × 1/3 = 1/15
C. 1/5 × 3 = 3/5
D. 5 ÷ 1/3 = 15
E. 1/3 ÷ 5 = 1/15
Answer:
A and D
Step-by-step explanation:
One pear is split into thirds. That means that one pear can become 3 slices. Because you have 5 pears, you have 15 slices. By multiplying 3 (slices) and 5 (pears), we receive the answer of 15 slices.
The answer is A and D.
Step-by-step explanation - Kylie brought 5 pears to practice. Because she cut each of them into thirds, this means that each pear equals 3 slices - therefore making the equation 5 x 3 = 15 and also making the equation 5 ÷ 1/3 because them two both equal 15.

Answer:
the inly way this could be a function is iif it is x times 0 plus 2
Answer:
yes
Step-by-step explanation:
You want to know if the relation shown is a function.
FunctionA set of ordered pairs (x, y) represents a function if there are no repeated x-values. Here, there are 4 unique x-values for the 4 ordered pairs (none are repeated), so this relation is a function.
__
Additional comment
Yes, it's that simple.
Look down the x-list. If you see any repeats, it is not a function. The same is true for ordered pairs (x, y). If there are any repeated first numbers, it is not a function.
