The measure of one angle is 130°. Which statement is true regarding the 130° angle and angle 3? They are same-side interior angles, so angle 3 measures 50°. They are alternate interior angles, so angle 3 also measures 130°. They are corresponding angles, so angle 3 also measures 130°. They are alternate exterior angles, so angle 3 measures 50°.
Answer:
Option B. ∠3 = 130°
Step-by-step explanation:
In the given question a, b, c are the parallel wires and pipe cleaner is the transverse.
Now we take two parallel wires a, c and pipe cleaner as transverse then
we have to find the relation between angle 4 and 130°
∠4 = ∠9 [ alternate interior angles ]
∠3 = 130° [ they are the alternate interior angles ]
Therefore option B. is the correct option.
Answer:
B. They are alternate interior angles, so angle 3 also measures 130°.
Step-by-step explanation:
Miguel can use all or part of his $25 gift card to make a music purchase. each song costs $1.50, and there is a $1.00 per account activation fee. which inequalities can represent this situation if m is the number of songs he can buy? select two options. 1 1.5 m less-than-or-equal-to 25 1 1.5 m greater-than 25 25 greater-than 1 1.5 m 1 1.5 m less-than 25 25 greater-than-or-equal-to 1 1.5 m
The inequalities that can represent this situation if m is the number of songs Miguel can buy are:
Option A: [tex]1 + 1.5m \leq25\\[/tex] Option E: [tex]25 \geq 1 + 1.5m[/tex] How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
For this case, it is provided that:
The price of an account activation = $1.00The price of a song = $1.50Total amount that Miguel has = $25m = number of songs that Miguel can buyIf he buys m = 0, he doesn't need to open an account, thus, saving all money of gift.
Else, if he buys m > 0, then:
Let c = total cost he will have to pay for m songs.
m songs will cost [tex]1.50 \times m[/tex] dollars
Total cost he will have to pay = account activation charge + m songs; cost
[tex]c = 1 + 1.5m[/tex]
(we don't write symbols like of currency generally, and understand it from context. Also, sign of multiplication is often hidden if there are non numeric symbols and numbers being multiplied are written together)
Since we have limited money, so:
c needs to be less than or equal to $25
This is symbolically written as:
[tex]c \leq 25[/tex]
But since we've got [tex]c = 1 + 1.5m[/tex], thus:
[tex]1 + 1.5m \leq25\\[/tex] (option A).
This can be reversed as:
[tex]25 \geq 1 + 1.5m[/tex] (Option E)
(both things are same, as [tex]c \leq 25[/tex] or [tex]25 \geq c[/tex] both are same since if c is less than or equal to 25, then that means 25 is greater than or equal to c)
(the case when c= 0, we have 0 < 25, so it is also included in those two options, as a special case)
Thus, the inequalities that can represent this situation if m is the number of songs Miguel can buy are:
Option A: [tex]1 + 1.5m \leq25\\[/tex] Option E: [tex]25 \geq 1 + 1.5m[/tex]Learn more about inequalities here:

Question 3:
Time taken by 1st delivery driver = t1 = 6 hours
Time taken by 2nd delivery driver = t2= 5 hours
Time together = T
[tex]{\dfrac{ 1 }{ T } = \dfrac{ 1 }{ t1 } + \dfrac{ 1 }{ t2 }}[/tex]

A hotel manager needs to buy beds and chairs. He has a total budget of 2000 dollars, and each bed costs $150 and each chair costs $50. Write an inequality to describe the possible number of beds and chairs that he can buy. If he buys 6 beds, what is the maximum number of chairs he can buy?
Answer:
The maximum number of chairs he can buy is C ≤ 22
Step-by-step explanation:
Let B represent the number of beds the hotel manager can buy.
Let C represent the number of chairs the hotel manager can buy.
Putting this into an expression, we have:
150B + 50C ≤ 2000
Since the hotel manager buys 6 beds, putting this into the information above:
150 (6) + 50C ≤ 2000
900 + 50C ≤ 2000
50C ≤ 2000 - 900
50C ≤ 1100
C ≤ 22

A school typically sells 500 yearbooks each year for $50 each. The economics class does a project and discovers that they can sell 100 more yearbooks for every $5 decrease in price. The revenue for yearbook sales is equal to the number of yearbook sold times the price of the yearbook. Let x represent the number of $5 decreases in price. If the expression that represents the revenue is in the form R(x)=(500+ax)(50-bx). Find the values of a and b.
we have to calculate the values of A and B, so we have to:
[tex]A=100\\B=5[/tex]
Since the equation is:
[tex]R(X)=(500+ax)(50-bx)[/tex]
And the following information was given:
A school typically sells 500 yearbooks each year for $50 each.
The economics class discovers that they can sell 100 more yearbooks for every $5 decrease in price.

A person invests 6500 dollars in a bank. The bank pays 4% interest compounded daily. To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 8900 dollars?
The time required for the invested money to reach the accrued amount is 8 years.
What is the time required to acquire the accrued amount?The compound interest formula is expressed as;
A = P(1 + r/n)^(n*t)
Where A is accrued amount, P is principal, r is rate, and t is time.
Given that;
Principal P = $6500Interest rate r = 4% = 4/100 = 0.04Compounded daily n = 365 dayAccrued amount A = $8900?Plug the given values into the compound interest formula and solve for time t.
A = P(1 + r/n)^(n*t)
t = In(A/P) / n[ In( 1 + r/n ) ]
t = (In( $8900 / 6500 )) / ( 365[ In( 1 + 0.04/365 ) ] )
t = (In( $8900 / 6500 )) / ( 365[ In( 1 + 0.04/365 ) ] )
t = 7.857
t = 8 years.
Therefore, the required time is 8 years.

y=4x+2
y=3x-2
Answer:
The solution is x = -4
Step-by-step explanation:
y=4x+2
we can see here that y equals 4x+2
y =3x-2
The y here is the same y, therefore we ban subtitute the first equation into the second one, like this:
y =3x-2
4x+2 = 3x-2
now just solve it algebraically.
4x + 2 - 3x = 3x -2 -3x
x +2 -2 = -2 -2
x = -4
The solution is x = -4
