Answer:
10°
Step-by-step explanation:
x + 25 = 3x + 5. [Vertically Opposite Angles]
=> 25 - 5 = 3x - x
=> 20 = 2x
[tex] = > \frac{20}{2} = x[/tex]
=> 10 = x
=> x = 10°(Ans)
Answer:
x=10
Step-by-step explanation:
x+25=3x+5
vertically opposite angles are equal
3x-x=25-5
x=20

Suppose that there are two types of tickets to a show: advance and same-day. The combined cost of one advance ticket and one same-day ticket is $ 40. For one performance, 25 advance tickets and 30 same-day tickets were sold. The total amount paid for the tickets was $1075 . What was the price of each kind of ticket?
Set up a set of 2 equations in 2 variables -
Let x = advance ticket cost and y = same-day tickets cost
Then
x+y=40 and
25x+30y=1075 >>>>> 5x+6y=215
x=40-y, so
5(40-y)+6y=215
200-5y+6y=215
y=15 >>>> x=25
5(25) + 6(15) = 125+90 = 215

Lisa and Alice are playing a game. Each player either receives or has to pay play money based on the results of their spin. The table lists how much a player receives or pays for various spins. What color has the greatest amount?
Red
Pays $5
Blue
Receive $4
Yellow
Pay $1
Green
Receive $3
Orange
Pay $2
Answers
Answer:
The amount in table as positive negative numbers: -5, 4, -1, 3, -2.
The spinner lands on red the change to Lisa's amount of money is -$5.
Step-by-step explanation:
Consider the provided table.
Part(A)
The table list how much a player receives or pays for various.
Paying some money is represented by a negative sign while receiving money is represented by a positive sign.
For red they needs to pay $5 which can be written as -5.
For blue they received $4 which can be written as 4.
For yellow they needs to pay $1 which can be written as -1.
For green they received $3 which can be written as 3.
For orange they needs to pay $2 which can be written as -2.
So, the amount in table as positive negative numbers: -5, 4, -1, 3, -2.
Part(B)
Now, we need to describe the change to Lisa’s amount of money when the spinner lands on red.
If spinner lands on red then she needs to pay $5.
Thus, if the spinner lands on red the change to Lisa's amount of money is -$5.

Solid A is dilated using a scale factor of 2⁄5, resulting in Solid B. Solid B is also dilated using a scale factor of 2⁄5, resulting in Solid C. If the volume of Solid B is 72 〖km〗^3, what is the volume of Solid A and Solid C?
Answers
Answer:
[tex]Solid\ A= 180km^3[/tex]
[tex]Solid\ C = 28.8km^3[/tex]
Step-by-step explanation:
Given
[tex]k_1 = \frac{2}{5}[/tex] from A to B
[tex]k_2 = \frac{2}{5}[/tex] from B to C
[tex]Solid\ B = 72km^3[/tex]
Required
Find the volumes of solids A and C
The expression that gives solid B from A is:
[tex]Solid\ A * k_1 = Solid\ B[/tex]
This gives:
[tex]Solid\ A * \frac{2}{5}= 72km^3[/tex]
Make A the subject
[tex]Solid\ A= 72km^3 * \frac{5}{2}[/tex]
[tex]Solid\ A= 36km^3 * 5[/tex]
[tex]Solid\ A= 180km^3[/tex]
Similarly:
The expression that gives solid C from B is:
[tex]Solid\ B * k_2 = Solid\ C[/tex]
This gives:
[tex]72km^3 * \frac{2}{5} = Solid\ C[/tex]
[tex]\frac{144km^3 }{5} = Solid\ C[/tex]
[tex]28.8km^3 = Solid\ C[/tex]
[tex]Solid\ C = 28.8km^3[/tex]

Step-by-step explanation:
a = 1b = 3c = 27[tex] \rm 6 {a}^{2} + 2bc - 2 {c}^{ \frac{1}{3} } [/tex]
[tex] = 6 {(1)}^{2} + 2(3)(27) - 2( {27)}^{ \frac{1}{3} } [/tex]
[tex] \rm = 6 + 162 - 2 ( \sqrt[3]{27} )[/tex]

Evaluate the following integral using trigonometric substitution
Integral underroot dx/ 9-x^2
Answers
Answer:
The result of the integral is:
[tex]\arcsin{(\frac{x}{3})} + C[/tex]
Step-by-step explanation:
We are given the following integral:
[tex]\int \frac{dx}{\sqrt{9-x^2}}[/tex]
Trigonometric substitution:
We have the term in the following format: [tex]a^2 - x^2[/tex], in which a = 3.
In this case, the substitution is given by:
[tex]x = a\sin{\theta}[/tex]
So
[tex]dx = a\cos{\theta}d\theta[/tex]
In this question:
[tex]a = 3[/tex]
[tex]x = 3\sin{\theta}[/tex]
[tex]dx = 3\cos{\theta}d\theta[/tex]
So
[tex]\int \frac{3\cos{\theta}d\theta}{\sqrt{9-(3\sin{\theta})^2}} = \int \frac{3\cos{\theta}d\theta}{\sqrt{9 - 9\sin^{2}{\theta}}} = \int \frac{3\cos{\theta}d\theta}{\sqrt{9(1 - \sin^{\theta})}}[/tex]
We have the following trigonometric identity:
[tex]\sin^{2}{\theta} + \cos^{2}{\theta} = 1[/tex]
So
[tex]1 - \sin^{2}{\theta} = \cos^{2}{\theta}[/tex]
Replacing into the integral:
[tex]\int \frac{3\cos{\theta}d\theta}{\sqrt{9(1 - \sin^{2}{\theta})}} = \int{\frac{3\cos{\theta}d\theta}{\sqrt{9\cos^{2}{\theta}}} = \int \frac{3\cos{\theta}d\theta}{3\cos{\theta}} = \int d\theta = \theta + C[/tex]
Coming back to x:
We have that:
[tex]x = 3\sin{\theta}[/tex]
So
[tex]\sin{\theta} = \frac{x}{3}[/tex]
Applying the arcsine(inverse sine) function to both sides, we get that:
[tex]\theta = \arcsin{(\frac{x}{3})}[/tex]
The result of the integral is:
[tex]\arcsin{(\frac{x}{3})} + C[/tex]

A consumer group studied two different manufacturers of cars, J and K, to investigate differences in gas
mileage for cars made by the two manufacturers. For a similar type of car, a random sample of 15 cars
from J and a random sample of 12 cars from K were selected, and the gas mileages, in miles per gallon
(mpg), were recorded. The difference in the sample mean gas mileages was used to construct the 90
percent confidence interval (3.5,5.7).
Assuming all conditions for inference were met, which of the following is a correct interpretation of the
interval?
А
The probability is 0.90 that the difference in sample means for gas mileage for the two
car manufacturers is between 3.5 mpg and 5.7 mpg
B
The probability is 0.90 that the population mean difference in gas mileage for the two car
manufacturers is between 3.5 mpg and 5.7 mpg
About 90 percent of the differences in gas mileage for the two car manufacturers are
between 3.5 mpg and 5.7 mpg.
D
We are 90 percent confident that the difference in sample means for gas mileage for the
two car manufacturers is between 3.5 mpg and 5.7 mpg.
E
We are 90 percent confident that the population mean difference of gas mileage for the
two car manufacturers is between 3.5 mpg and 5.7 mpg.

170/2=85
8*10=80
80/2=40
85+40=125
Answer:
125 square meters
Step-by-step explanation:
Decomposition: Breaking up the shapes, finding their areas individually, and adding up their areas.
Area of a triangle: base * height * 0.5
First, let's look at the area of the top left triangle. The base is 5, while the height is 17. Thus, its area is
5 * 17 * 0.5 = 42.5
The bottom left triangle has a base of 5, and a height of 17, so its area is
5 * 17 * 0.5 = 42.5
The top right triangle has a height of 8 and a base of 5, so its area is
5 * 8 * 0.5 = 20
The bottom right triangle has a height of 8 and base of 5, so its area is
5 * 8 * 0.5 = 20
Now, add up all the areas.
42.5 + 42.5 + 20 + 20 = 125
Thus, the answer is 125 square meters.
