Answer:
x=4
Step-by-step explanation:
the ones on top of each other you are adding together so -10x + -2x equals -12x and -32+-16 equals -48 and -48 divided by -12x equals positive 4
Answer:
Step-by-step explanation:
you can see from the picture that adding 2y and -2y cancels out. So the remaining parts of the equations are
-10x=-32
-2x=-16
add the two together:
-12x=-48
x=4
Monica and Brianne each draw one prize ticket at random from different boxes. Monica has a 20% chance of winning a prize. Brianne has a 1/10 chance of winning a prize. Is Monica or Brianne more likely to win a prize? Explain your reasoning.
Answer: Monica
Step-by-step explanation:
Given
Monica has a 20% chance of winning a prize
Brianne has a [tex]\frac{1}{10}[/tex] chance of winning a prize
20% chance refers to
[tex]\dfrac{20}{100}=\dfrac{2}{10}[/tex]
As
[tex]\dfrac{2}{10}>\dfrac{1}{10}[/tex]
therefore, monica is more likely to win the prize.

Help! I don't understand this.
Answer:
x > 9.
Step-by-step explanation:
Here it is just simplifying the inequality.
6 - 2/3x < x - 9
Add 2/3x to both sides.
6 < 5/3x - 9
Add 9 to both sides.
15 < 5/3x
Multiply by 3/5.
9 < x
Flip it.
x > 9.

Step-by-step explanation:
Intersecting Secants Theorem:
6(x + 6) = 8(8 + 10)
6x + 36 = 8(18)
6x + 36 = 144
6x = 144 - 36
6x = 108
x = 18

What is the range of 4,3,3,6,10,7,4,3
Step-by-step explanation:
We have,
3,3,3,4,4,6,7,10
The largest number (L) = 10
The smallest number(S) = 3
Since, the range is the difference between the largest and the smallest value given in the data,
Here,
R = L-S
= 10-3
= 7
Thus Range = 3

Answer:
4
Step-by-step explanation:
The given equation of circle is:
[tex] (x+2)^2 +(y-3)^2 =4 [/tex]
[tex] (x+2)^2 +(y-3)^2 =2^2 [/tex]
Equating it with:
[tex] (x-h)^2 +(y-k)^2 =r^2 [/tex]
We find:
[tex] r^2=2^2 [/tex]
[tex]\therefore r=2 [/tex]
Radius of the circle = 2 units
Therefore,
Diameter of the circle = 2*2= 4 units

First, we determine the cost function for all the three rides.
Ride A
From the graph, we have the following points
[tex](x_1,y_1) = (0,8)[/tex]
[tex](x_2,y_2) = (2,12)[/tex]
Calculate slope
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{12-8}{2-0}[/tex]
[tex]m = \frac{4}{2}[/tex]
[tex]m =2[/tex] --- This represents the rate per ride
The equation is the calculated as:
[tex]y = m(x - x_1) + y_1[/tex]
So, we have:
[tex]y = 2(x - 0) + 8[/tex]
[tex]y = 2(x) + 8[/tex]
[tex]y = 2x + 8[/tex]
So, the cost function is:
[tex]C(x) =2x + 8[/tex]
Calculate the cost of admission i.e. x=0
[tex]C(0) = 2*0+8 = 8[/tex]
So, we have:
[tex]C(0) = 8[/tex] --- Admission Charge
[tex]C(x) =2x + 8[/tex] --- Cost function
[tex]m =2[/tex] --- Rate per ride
Ride B
From the table, we have the following points
[tex](x_1,y_1) = (0,12)[/tex]
[tex](x_2,y_2) = (4,15)[/tex]
Calculate slope
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{15-12}{4-0}[/tex]
[tex]m = \frac{3}{4}[/tex]
[tex]m = 0.75[/tex] --- This represents the rate per ride
The equation is the calculated as:
[tex]y = m(x - x_1) + y_1[/tex]
So, we have:
[tex]y = 0.75(x - 0) + 12[/tex]
[tex]y = 0.75(x) + 12[/tex]
[tex]y = 0.75x + 12[/tex]
So, the cost function is:
[tex]C(x) = 0.75x + 12[/tex]
Calculate the cost of admission i.e. x=0
[tex]C(0) = 0.75*0 + 12=12[/tex]
So, we have:
[tex]C(0) =12[/tex] --- Admission Charge
[tex]C(x) = 0.75x + 12[/tex] --- Cost function
[tex]m = 0.75[/tex] --- Rate per ride
Ride C
No additional fee;
So, the cost function is;
[tex]C(x) = 30[/tex]
In summary, we have:
Ride A
[tex]C(x) =2x + 8[/tex] --- Cost function
[tex]m =2[/tex] --- Rate per ride
Ride B
[tex]C(x) = 0.75x + 12[/tex] --- Cost function
[tex]m = 0.75[/tex] --- Rate per ride
Ride C
[tex]C(x) = 30[/tex] --- Cost function
By comparison
Ride A has the highest rate per ride of (#2), followed by ride B with a rate of #0.75 per ride.
Ride C has no charges per ride
The impact on the total cost is that:
Ride A: People that opt for ride A will pay the least to get admitted (i.e #8) but they pay the most (i.e. #2) per each ride they take
Ride B: People that opt for ride B will pay #12 to get admitted, but they pay 0.75 per each ride they take
For A and B, the overall cost depends on the number of rides taken.
Ride C: Irrespective of the number of rides taken, people that opt for ride C will pay the same flat fee of #30

A triangle has two sides measuring 8 and 15. The included angle is 33°. What is the length of the side opposite the 33° angle?
Answer:
Measure of the side opposite to the angle measuring 33° is 9.37 unit
Step-by-step explanation:
If a, b and c are the sides of a triangle,
And 'a' = 8
b = 15
Measure of the Included angle C = 33°
By applying cosine rule in the given triangle,
c² = a² + b² - 2abcos(C)
c² = 8² + (15)² - 2(8)(15)cos(33°)
= 64 + 225 - 201.28
= 87.72
c = √87.72
c = 9.266
≈ 9.27
Therefore, measure of the side opposite to the angle measuring 33° is 9.37 units

120

400
400
Answer:
80
Step-by-step explanation:
Look at the figure below. The perimeter is the same as if the corners were moved out to form a square. Then you have 4 congruent sides of length 20.
P = 4 * 20 = 80
The perimeter of a shape is the summation of the sides of the shape. The perimeter of the shape is 80 units.
From the attached figure, we have the following observations
All sides of the shape are either vertical or horizontal lineNone of the side lengths overlapsThis means that if the shape is drawn (see attachment) to have 4 sides, opposite sides of the shape will be congruent.
The first side length is:
[tex]Length = 20[/tex]
While the adjacent side length is:
[tex]Width = 12 + 8 =20[/tex]
The perimeter (P) of the shape is then calculated as follows:
[tex]P = 2 \times (Length + Width)[/tex]
[tex]P = 2 \times (20 + 20)[/tex]
[tex]P = 2 \times 40[/tex]
[tex]P = 80[/tex]
Hence, the perimeter of the shape is 80 units.

The half life of a chemical element substance is 16 days, How long will it takes for the substance to decay from 120mg to 2 mg
Answer:
94.5 days
Step-by-step explanation:
We are asked to calculate the time.
The formula to calculate the time for half life =
t = t½ × In (Nt/No)/-In2
t½ = half life = 16 days
No = Initial substance = 120mg
Nt = Amount of substances after time t = 2 mg
t = 16 × In (2/120)/-In2
t = 94.510249529736 days
Approximately = 94.5 days
Therefore, the time it would take for the substance to decay from 120mg to 2 mg is 94.5 days.
