Answer:
$28.44
Step-by-step explanation:
Time and a half is the normal rate of pay when working overtime at any job and is calculated as 1.5 times the regularly hourly wage of the employee. Therefore we can calculate how much she earns per hour of overtime by doing the following...
$9.48 * 1.5 = $14.22 per hour
Now we can see that Odette earns $14.22 per hour of overtime, since she worked two hours we simply multiply this amount by 2.
$14.22 * 2 = $28.44
Odette Alvarez earned $28.44 for the two hours of overtime.

A local charity sponsors a 5K race to raise money. It receives $55 per race entry and $10,000 in donations, but it must spend $15 per race entry to cover the cost of the race. Write and solve an inequality to determine the number of race entries the charity needs to raise at least $55,000.
Step-by-step explanation:
$55,000 - $10,000 = $45,000
$55 - $15 = $40
$45,000 : $40 = 1,125 race entries needed

Step-by-step explanation:
15 members of the Drama Club can make set decorations for their musical in 12 hours. After 4 hours have passed, a few teachers came to help, and the group completed the remaining work in 6 hours. How many teachers helped?
PLEASE help!!! I WILL AWARD BRAINLIEST.
Answer:
5 teachers
Step-by-step explanation:
We know that the 15 members finished 1/3 of the job in 4 hours. When the teachers came they finished 2/3 of the job in 6 hours. So they finished 1/3 of the join in 3 hours of we simplify it.
4 hour: 15 minutes
3 hour: ?
15/3 x 4= 20 teaches. Then we do 20-15=5 because there were originally 15 members.
The time spent and the number of people are illustrations of ratio and proportions.
5 teachers helped the 15 members of the drama club
We have:
[tex]t= 12hrs[/tex] --- time
[tex]n = 15[/tex] --- members of the drama club
After four hours, the amount of time left is 8 hours.
So, we have:
[tex]15\ members \to 8\ hours[/tex]
But the teachers joined them, and they finished in 6 hours.
So, we have:
[tex](x + 15) \to 6\ hours[/tex]
Where x represents the number of teachers
Rewrite as:
[tex]15\ members \to 8\ hours[/tex]
[tex](x + 15) \to 6\ hours[/tex]
Multiply
[tex](x + 15) \times 6 = 15 \times 8[/tex]
[tex]6x + 90 = 120[/tex]
Collect like terms
[tex]6x = 120 - 90[/tex]
[tex]6x = 30[/tex]
Divide both sides by 6
[tex]x = 5[/tex]
Hence, 5 teachers helped them.

Suppose there are three brands of laundry detergent: A, B, and C. Let Xn be the brand chosen on the nth purchase, where the states are 0 (brand A), 1 (brand B), and 2 (brand C). Customers who try these brands are satisfied and chose the same thing again on the next purchase with probabilities 0.5, 0.7, and 0.3, respectively. The probability a customer will change brands on their next purchase to one of the other two brands is equally likely. Write the one-step transition probability matrix.
find all the points (-105,y) that are 17 units from the point P (-97,2)
Answer:
The points that are 17 units from P(-97,2) are:
(-105,-13) and (-105,17)
Step-by-step explanation:
Distance between two points
The distance between points A(x,y) B(w,z) can be calculated with the formula:
[tex]d=\sqrt{(w-x)^2+(z-y)^2}[/tex]
One point is (-105,y) and the other is (-97,2). Computing the distance between them:
[tex]d=\sqrt{(-97-(-105))^2+(2-y)^2}=\sqrt{8^2+(2-y)^2}=\sqrt{64+(2-y)^2}[/tex]
This distance is 17, thus:
[tex]\sqrt{64+(2-y)^2}=17[/tex]
Squaring on both sides:
[tex]64+(2-y)^2=289[/tex]
Operating:
[tex](2-y)^2=289-64=225[/tex]
Taking the square root:
[tex](2-y)=\pm 15[/tex]
There are two possible solutions:
[tex]2-y=15\Rightarrow y=-13[/tex]
[tex]2-y=-15\Rightarrow y=17[/tex]
The points that are 17 units from P(-97,2) are:
(-105,-13) and (-105,17)
what is an equation of the line that passes through the points (0,-7) and (-6,-2)
Answer:
y=(-5/6)x-7
Step-by-step explanation:
Let the line graph y=ax+b,
b=-7 as (0,-7) is y-intercept
To get a (slope), slope a = (y2-y1)/(x2-x1) = (-2-(-7))/(-6-0)=-5/6
Thus, y=(-5/6)x-7

Find cos2θ if sinθ=11/61
Answer:
given cos(2θ) = 1 - 2 sin²(θ)
=> cos(2θ) = 1 - 2(11/61)²
=> cos(2θ) = 1 - 2* 121/3721
=> cos(2θ) = 1 - 242/3721
=> cos(2θ) = 3479/3721
Step-by-step explanation:
The value of cos 2θ is = 3479 / 3721 or 0.9349
What are trigonometric relations?
Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
Given data ,
Let the value of sin θ = 11 / 61
So , the value of cos 2θ = 1 - 2sin²θ
On simplifying the equation , we get
sin θ = 11 / 61
sin²θ = ( 11/61 )²
So , substituting the value in the equation , we get
cos 2θ = 1 - 2sin²θ
cos 2θ = 1 - 2( 11/61 )²
= 3721 - ( 242 / 3721 )
= 3479 / 3721
cos 2θ = 0.9349
Therefore , the value of cos 2θ = 0.9349
Hence , The value of cos 2θ is = 3479 / 3721 or 0.9349

In ΔIJK, ∠K \cong≅∠J, IJ = 9 and JK = 10. Find the length of KI.
Answer:
KI = 9
Step-by-step explanation:
Given that triangle IJK has two equal base angles, angle J and angle K, this meets the definition of an isosceles triangle.
An isosceles triangle has two equal angles. Therefore, the side lengths opposite each of the equal base angles of ∆IJK would be of equal lengths.
Given that IJ which corresponds to angle K = 9, and JK, which corresponds to the other 3 angle, therefore, the length of KI which corresponds to angle J would be the same length as the length of IJ = 9.
<k is congruent to <J
IJ = 9, therefore, IJ = KI
KI = 9.

A furniture company manufactures desks and chairs. Each desk uses four units of wood, and each chair uses three units of wood. A desk contributes $400 to profit, and a chair contributes $250. Marketing restrictions require that the number of chairs produced be at least twice the number of desks produced. There are 2000 units of wood available.
1. High level model is setup for you to plug in and solve.
2. If you want to practice creating the model, you don't need to use the model setup in the second tab.
3. Use Solver to maximize the company’s profit. Make sure to name the cells properly to get full credit.
4. Use $ format for cells like cost, profit etc. Fill the information for objective function & constraints.
Step-by-step explanation:
Although I cannot find any model or solver, we can proceed to model the optimization problem from the information given.
the problem is to maximize profit.
let desk be x
and chairs be y
400x+250y=P (maximize)
4x+3y<2000 (constraints)
according to restrictions y=2x
let us substitute y=2x in the constraints we have
4x+3(2x)<2000
4x+6x<2000
10x<2000
x<200
so with restriction, if the desk is 200 then chairs should be at least 2 times the desk
y=2x
y=200*2
y=400
we now have to substitute x=200 and y=400 in the expression for profit maximization we have
400x+250y=P (maximize)
80000+100000=P
180000=P
P=$180,000
the profit is $180,000
