Answer:
x = 1.5
Step-by-step explanation:
Here, we want to solve for the value of x
By using the tangent from the same point theorem, we have it that;
lh^2 = lj * lk
1^2 = (0.5) * (0.5 + x)
1 = 0.5x + 0.25
1-0.25 = 0.5x
0.5x = 0.75
x = 0.75/0.5
x = 1.5

Answers
Answer:

Step-by-step explanation:
my guess
it's supposed to be the a number closest to 1 or-1

The answer to this question is:
0.8
What is line of best fit and correlation coefficient?
A straight line that best approximates the given set of data is known as a line of best fit. It is a line that, on a graph, roughly straddles the center of each scatter point. The association is stronger the closer the points are to the line of greatest fit.
The equation of a line of a best fit is represented as: y=mx + c
To gauge how closely two variables are related to one another, correlation coefficients are used.
Solution:
In order to determine how closely related two sets of data are, correlation coefficient formulas are used. The formulas provide a value in the range of -1 and 1, where
1 denotes a strongly positive association.A score of -1 indicates a very adverse association.A result of zero means there is absolutely no associationThe strength of the link between the variables increases with the distance between the coefficients of +1.0 and -1.0.
-0.9 is a value which is greater than -0.8, so the values which are greater than -0.8 are not considered as strong correlation coefficient.
Whereas the values which are less than 0.8 are also not considered as strong coefficients.
Hence 0.8 is the correlation coefficient which represents the strongest linear relationship.

Terell jackson opened a savings account by depositing his $1,050 paycheck his bank pays 12% interest compound a monthly basis he doesn't make any other deposits or withdrawals after three years how much interest will he earn
Answers
Answer:
Interest= $516.93
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $1,200
Number of periods (n)= 12*3= 36 months
Interest rate (i)= 0.12/12 = 0.01 monthly
First, we need to calculate the future value of the investment using the following formula:
FV= PV*(1 + i)^n
FV= 1,200*(1.01^36)
FV= $1,716.93
Now, the interest earned:
Interest= 1,716.93 - 1,200
Interest= $516.93
There about fifteen hundred players in the nfl in a survey of a random sample of 50 players three players were hurt how many players in the nfl would be excpected to get hurt
Answers
Answer: 90 players.
Step-by-step explanation:
Since we are informed that in a survey of a random sample of 50 players, 3 players were hurt. This gives a fraction of 3/50 for those that are hurt.
Therefore, in a survey of 1500 players, the number of players expected to be hurt will be:

Are the two triangles similar? How do you know?
Answers
Answer:
Yes, they are similar in terms of the size of their angles.
Step-by-step explanation:
The angles of a triangle always add up to 180°, so
Triangle CDE's missing angle: 180 - (60 + 53) = 67
Triangle FGH's missing angle: 180 - (67 + 60) = 53
Answer:
Yes, the triangles are similar
Step-by-step explanation:
In order for two triangles to be similar, at least two corresponding angles must be congruent.
We know DCE and GFH are congruent, because they are both 60°, so that's one angle down, now we need one more.
We can either choose to see if CDE and FGH are the same, or CED and FHG. I'll choose CDE and FGH.
We know CDE is 53°, so we need to find FGH to see if it's also 53°.
The sum of the interior angles of a triangle are 180°, so we can find FGH by doing 180-60-67=53°, so CDE and FGH are congruent.
Knowing DCE and GFH are congruent, and CDE and FGH are congruent, we can say that these triangles are similar.

On a car trip, the time of trip is inversely proportional to the speed traveled.
One car drove 46 mph and it took them 41 minutes. If a different car made
the same trip at a speed of 82 mph, how many minutes would the trip take?
Answers
The car will take 23 minutes to complete the trip if in a car trip, the time of trip is inversely proportional to the speed travelled.
What is a proportional relationship?It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.
Let T is the time and S is the speed.
Then,
T ∝ 1/S
T = k/S
k is the constant of proportionality
Plug T = 41 minutes = 0.683 hour and S = 46 mph
0.683 = k/46
k = 31.418 m
T = 31.418/S
Plug S = 82 mph
T = 31.418/82 = 0.383 hour (multiply it by 60 to convert it into the minutes)
T = 22.988 minutes ≈ 23 minutes
Thus, the car will take 23 minutes to complete the trip if in a car trip, the time of trip is inversely proportional to the speed travelled.

Step-by-step explanation:
We can see in the sample that 18/50 people bring lunches to school. If we divide 18 by 50 we get 0.36 now we know that 36% of people bring their lunches in the sample. Now we take that number and multiply it by 942.

Answers
Answer:
C. 3(2x + 5y) is the algebraic expression equivalent to the expression
Step-by-step explanation:
From the question, the given expression is 6x + 15y.
Factorizing this expression gives 3(2x + 5y). Hence, the algebraic expression equivalent to the expression 6x + 15y is 3(2x + 5y). (Option C).
Checking the remaining options
A. 3(2x - 5y)
Expanding this gives 6x - 15y. It is not equivalent to the given expression
B. 3(5x - 2y)
Expanding this gives 15x - 6y. It is not equivalent to the given expression
D. 3(5x + 2y)
Expanding this gives 15x + 3y. It is not equivalent to the given expression.
Hence, C. 3(2x + 5y) is the algebraic expression equivalent to the expression.

If two lines are parallel and they are defined by the equations, y=4x-5 and y=ax+2, what is the value of a?
Answers
Answer:
[tex]a=\dfrac{4x-7}{x}[/tex]
Step-by-step explanation:
The equations of lines are :
y=4x-5 and y=ax+2
From above equations,
4x-5 = ax+2
4x-ax = 5+2
4x-7 = ax
[tex]a=\dfrac{4x-7}{x}[/tex]
So, the value of a is equal to [tex]\dfrac{4x-7}{x}[/tex].
