The figure below shows two parallel lines intersected by a third line. What is the value of x
Answer:
[tex] x = 20 [/tex]
Step-by-step explanation:
The two angles given in the diagram are alternate interior angles. Alternate interior angles are congruent. Therefore:
(4x)° = (x + 60)°
Use the equation to solve for the value of x
[tex] 4x = x + 60 [/tex]
Subtract x from both sides
[tex] 4x - x = x + 60 - x [/tex]
[tex] 3x = 60 [/tex]
Divide both sides by 3
[tex] \frac{3x}{3} = \frac{60}{3} [/tex]
[tex] x = 20 [/tex]

Amanda buys 4 tickets to a baseball game for $24. Which equation shows the closest estimate of the total amount Amanda spent?
Amanda spent 6 dollars for each ticket for a baseball game.
What is an equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
Total money spent = $24
Number of the tickets = 4
SO cost of each ticket will be:-
Cost = 24 / 4 =6
Therefore Amanda spent 6 dollars for each ticket for a baseball game.

-2 (-x + 4) + 4x - 3 = 31
Answer:
The value of x is 7.
Step-by-step explanation:
First, you have to expand the brackets and then, solve it :
[tex] - 2( - x + 4) + 4x = 31[/tex]
[tex]2x - 8 + 4x - 3 = 31[/tex]
[tex]6x - 11 = 31[/tex]
[tex]6x = 31 + 11[/tex]
[tex]6x = 42[/tex]

Change general form of hyperbola into standard: -x^2 + y^2 -16x + 14y - 251 = 0
Answer:
(y+7)²/364 - (x+8)²/364 = 1
Step-by-step explanation:
This is the standard form of a vertical hyperbola (y-k)²/a² - (x-h)²/b² = 1
so, (y²+14y+?) - (x²+16x+?) = 251
(y²+14+49)-49 - (x²+16x+64)-64 = 251
(y+7)² - (x+8)² = 251 + 49 + 64
(y+7)² - (x+8)² = 364
(y+7)²/364 - (x+8)²/364 = 1
The previous exercises states that the distribution of speeds of cars traveling on the Interstate 5 Freeway (I-5) in California is nearly normal with a mean of 72.6 miles/hour and a standard deviation of 4.78 miles/hour. The speed limit on this stretch of the I-5 is 70 miles/hour. 5. A highway patrol officer is hidden on the side of the freeway. What is the probability that 5 cars pass and none are speeding? Assume that the speeds of the cars are independent of each other.
Answer:
The probability is [tex]P(X \le 70 ) = 0.7054 [/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 72.6 \ miles /hour [/tex]
The standard deviation is [tex]\sigma = 4.78 \ miles /hour[/tex]
The speed limit is [tex]x = 70 \ miles /hour[/tex]
Generally the probability that 5 cars pass and none are speeding is equivalent to the probability that the speed of the cars is less than x which is mathematically represented as
[tex]P(X \le x ) = 1 - P(X > x )[/tex]
Now
[tex]P(X > x) = P(\frac{X - \mu}{\sigma } >\frac{x - \mu}{\sigma } )[/tex]
Generally
[tex] \frac{X - \mu}{\sigma } = Z (The \ standardized \ value \ of \ X)[/tex]
So
[tex]P(X > 70) = P(Z >\frac{70 - 72.6}{72.6 } )[/tex]
[tex]P(X > 70) = P(Z > -0.54 )[/tex]
From the z-table
[tex] P(Z > -0.54 ) = 0.2946[/tex]
=> [tex]P(X > 70) = 0.2946 [/tex]
So
[tex]P(X \le 70 ) = 1 - P(X > 70 ) [/tex]
=> [tex]P(X \le 70 ) = 1 - 0.2946 [/tex]
=> [tex]P(X \le 70 ) = 0.7054 [/tex]

How do you do this question?
Step-by-step explanation:
arctan(x) is less than π/2 for x > 0. Therefore, if we say g(x) = 13 (π/2) / eˣ, then f(x) < g(x) for all values of x > 0.
g(x) = 13 (π/2) / eˣ
g(x) = 13π/2 · (1/e)ˣ
So g(x) is a geometric series where r = 1/e. Since |r| < 1, the series converges.
Since g(x) converges, the smaller f(x) also converges.

Estimate the difference to the nearest hundredth 8.394-2.199
The subtraction between 8.394 and 2.199 is estimated as 6.2
Subtraction of NumbersTo subtract two or more values from one another, we simply take one of the value from the other. Subtraction is a mathematical operation in mathematics that is aimed at reducing the value of a quantity.
In this case, the subtraction of the two numbers will leave a decimal value.
This is because both number subtracting from one another are decimal numbers
8.394 - 2.199 = 6.195
However, the question clearly asked we estimate the difference between the two values.
What we need to do is round up or round down the numbers to the nearest significant number.
We round down 8.394 ≅ 8 .4
We round up 2.199 ≅ 2.2
Subtracting these two numbers from one another, we would have 6.2

Answer:
f (k)
Step-by-step explanation:
Here, we are required to determine the value of f(-4) given the graph of a function f(x) as in the attached image.
The value of f(-4) given the graph of the function f(x) as in the attached image is; f(-4) = 2.The graph of the function f(x) is a curve, where x is the independent variable and f(x) is dependent on the value of x.

Between 11 P.M. and 8:36 A.M., the water level in a swimming pool decreased by 8 25 in. Assuming that the water level decreased at a constant rate, how much did the water level drop each hour?
Answer:
0.8594 in/hr
Step-by-step explanation:
Decreased in the water level is 8.25 in.
Time 11 P.M. and 8:36 A.M. is 9 hr 36 min = 9.6 hr.
The rate of decreasing water level is constant.
So, [tex]\text{Rate}=\frac{\text{Level decreased}}{\text{Time taken}}[/tex]
[tex]\Rightarrow \text{Rate}=\frac{8.25}{9.6}=0.8594 in/hr[/tex].
Hence, the water level drop at the rate of 0.8594 in/hr.
Suppose there are 106 (1 million) asteroids that are 0.87 km in radius. If they were all combined into a single sphere, calculate the radius of this sphere in km.
Answer:
87km
Step-by-step explanation:
Volume is proportional to radius cubed, so radius is proportional to the cube root of volume.
Increase volume by a factor of 10^6 and radius increases by a factor of the cube root of 10^6, which is 10^(6/3) = 10^2 = 100.
100 * 0.87 km = 87 km
