Which of the following statements would best represent the value of a? PLEASE HELP
Answers
Answer:
The statement would best represent the value of a is a = [tex]\frac{6}{tan(38)}[/tex] ⇒ c
Step-by-step explanation:
In the right angle triangle, we can use the trigonometry ratios to find the missing sides or angles
sin β = [tex]\frac{opposite}{hypotenuse}[/tex]cos β = [tex]\frac{adjacent}{hypotenuse}[/tex]tan β = [tex]\frac{opposite}{adjacent}[/tex]In the given right triangle
∵ There measure of an acute angle is 38°
∵ The adjacent side to this angle is a
∵ The opposite side to this angle is 6
→ We will use the tangent ratio because we have the opposite and
adjacent sides of the given angle
∴ tan(38°) = [tex]\frac{6}{a}[/tex]
→ Multiply both sides by a to cancel the denominator in the right side
∴ a · tan(38°) = 6
→ Divide both sides by tan(38°) to find a
∴ a = [tex]\frac{6}{tan(38)}[/tex]
∴ The statement would best represent the value of a is a = [tex]\frac{6}{tan(38)}[/tex]

Look at the question and the student work below. In complete sentences, describe the mistake the student made and explain how to answer the question properly. Be sure to include a description of the algebraic steps required to solve for x and find the correct measure of the indicated angle.
Answers
Answer:
The equations should have been added up to equal 180 instead of being set to equal each other. The two are supplementary angles, which can be seen due the rule that a pair of interior angles on the same side of the transversal is supplementary. To fix this issue from the work that they did, they should subtract the 140 from 180, so the correct measure of DKH is actually 40 degrees.

A team's "winning percentage" shows how often it won. The team's "opponents' winning percentage" shows how often all its opponents won. But those opponents also played against other teams. Our team didn't have a chance to play against them. The "opponents' opponents winning percentage" shows how often all those other teams won. Summarize this in your own words.
Answers
Answer and explanation:
If a team's winning percentage denotes how often it has won then,
Then assume that it has won 7 out of 10 times then it has won 70% of the time
If the team's opponents' winning percentage denotes how often each has won without haven to face the team, then assume that each opponent has won 6 out of 10 times then it has each opponent has won 60% of the time(it could be different percentages if teams have won different number of games for each 10 games played)
If each opponent's opponents have each won 5 out of 10 times, 8 out of 10 times, 7 out of 10 times(assuming 3 groups, say 3 each, of opponents for 3 teams) then the groups must have won 50%, 80% and 70% of the time.

You want to purchase a new bike that costs $142.68. To save for the bike, you mow your neighbor's yard for $40 each week. How much money will you have left over if you buy the bike after saving for 4 weeks?
Answers
The amount of money left after purchasing the bike is $17.32
How to calculate the amount of money left ?The cost of the new bike is $142.68
I need to save for the new bike and i decided to mow the neighbour's yard
The money paid is $40, this will be done for 4 weeks
At the end of the four weeks, the money i will get can be calculated as follows
= 40 × 4
= 160
To calculate the money left, let's subtract the cost of the bike from 160
= 160 - 142.68
= 17.32
Hence the amount of money left after buying the bike is $17.32

C: 42x - 8y - 5.3
D: 84x - 16y - 5.3
Answers
Answer:the answer is a
Step-by-step explanation:
The expression 2(14x - 3y + 28x + 12.2 - 5y - 17.5) is equivalent to the expression 84x - 16y -10.6 option (A) is correct.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
We have an expression:
= 2(14x - 3y + 28x + 12.2 - 5y - 17.5)
= 28x - 6y + 56x + 24.4 - 10y - 35
Adding like terms
= 84x - 16y -10.6
Thus, the expression 2(14x - 3y + 28x + 12.2 - 5y - 17.5) is equivalent to the expression 84x - 16y -10.6 option (A) is correct.

Consider the system of equations shown below. y = negative 5 x + 1. y = negative 5 x + 10 When graphed, the system consists of two lines that will never meet, no matter how far they are extended. Why are the lines parallel? The linear equations have the same slope and y-intercept. The linear equations have different slopes and y-intercepts. The linear equations have the same slope but different y-intercepts. The linear equations have different slopes but the same y-intercept.
Answers
The reason why both graphs are parallel because they have the same slope but different y-intercept.
Think about it. If both graphs have same slope and same y-intercept. The graph will intercept each others infinitely.
Then if we change the y-intercept into any numbers that aren't the same as another equations for ex.
y = -5x+1 and y = -5x+10
then we will get the parallel graph. Or if you solve the equation, the equation will not be true, thus giving the graph parallel.
But if it is y = -5x+1 and y = -5x+1 which both are the same graph. Then the graph will intercept each others infinitely. Or if we solve the equation, we will get 0 = 0 which makes the equation true for all real numbers.
Therefore, the reason why both graphs are parallel is because that they have the same slope but different y-intercept.
That's all.

Most staircases in use today have 9−inch treads and 8 12 −inch risers. What is the slope of a staircase with these measurements? Give your answer as a fraction or rounded to four decimal places, if necessary
Answers
Answer:
The value is [tex]m = 0.9022[/tex]
Step-by-step explanation:
From the question we are told that
The length of the treads is [tex]a = 9 \ inch[/tex]
The length of the risers is [tex]b = 8.12 \ inch[/tex]
Generally the slope of the staircase is
[tex]m = \frac{b}{a}[/tex]
=> [tex]m = \frac{8.12}{9}[/tex]
=> [tex]m = 0.9022[/tex]

The equation of the exponential function will be:
y = 12·(2)ˣStep-by-step explanation:
The general exponential function is defined as
y = abˣ
Here,
a is the initial value and b is the growth factor
From the table, it is clear that the y-intercept is (0, 12). Note that the y-intercept can be determined by setting x=0 and solving for y.
here
at x=0, y=12
so a = 12
If we check the y-values, it is clear that every next value of y can be obtained by multiplying the previous y-value by 2.
In other words, the common multiplier = b = 2
Thus, the equation becomes
y = 12·(2)ˣ
Thus, the equation of the exponential function will be:
y = 12·(2)ˣTrinity's car gets 26.5 miles per gallon of gas. Trinity is taking a trip that requires 14 gallons of gas. Which of the following best represents the number of liters of gasoline the trip will require? ( 1 gal ≈ 3.79 liters)
