The solution to the proportion 2/8 = -30/x is x = -120, found by cross multiplying and simplifying the resulting equation.
To solve the proportion 2/8 = -30/x, we will cross multiply to find the value of x. After cross multiplying, we obtain 2x = -30 imes 8. Simplifying this gives us 2x = -240, and dividing both sides by 2 yields x = -120. So the solution to the proportion is x = -120.

If angleA and angleB are vertical angles, and angleA = 38°, find the measure of angleB. A. B = 7° B. B = 57° C. B = 38° D. B = 142°
Answer:
C. B = 38°
Step-by-step explanation:
A vertical angle is created when two lines intersect, and are a pair of two non adjacent angles that are opposite from the origin, so both angles are going to measure the same.
Since both vertical angles are the same, both measure 38º.
Vertical angles are shown in the image:In this case the angle A would be the omega, and the B is the alfa.
If a person wanted to purchase their dream car, and keep it for many years, should they lease or buy? Why? (Site 1)
Buying an asset or a vehicle means paying off the entire sum of money that is the cost of the asset at the time of its purchase.
Leasing an asset means purchasing an asset by not paying the entire sum of money at the time of purchasing, rather paying in the form of rent over the period of time.
If a person wants to purchase his dream car for keeping for many years, then Buying Option is better because the payment of the overall cost in buying will be less than leasing.
This will also provide benefit that at the time of sale the owner will be paid off higher value of car as compared to car taken on lease.

If a person wants to purchase their dream car and keep it for many years, it is generally recommended to buy rather than lease. Buying a car provides long-term ownership, customization options, and potential resale value, while leasing offers lower monthly payments but no ownership.
Explanation:If a person wants to purchase their dream car and keep it for many years, it is generally recommended to buy rather than lease. Here are the reasons why:
Ownership: When you buy a car, you become the owner and have the freedom to modify or personalize the vehicle as you wish. Leasing, on the other hand, only provides temporary possession of the car.Long-term cost: Buying a car may have higher upfront costs, such as a down payment and monthly loan payments, but in the long run, you will own the vehicle. Leasing involves lower monthly payments, but you will not own the car at the end of the lease term.Resale value: Owning a car allows you to build equity over time. You can sell the car later and recoup some of the cost. Leasing does not provide this opportunity.In conclusion, buying a car is a better option if you want long-term ownership and the ability to customize the vehicle. Leasing may be suitable for those who prefer lower monthly payments and don't want to commit to long-term ownership.
True or False
The sum of two trinomials is ALWAYS a trinomial
Answer:
True.
Step-by-step explanation:
If the two trinomials are given as
x³ + 2x² + 4 = 0
and
2x³ + x² - 3 = 0
Then by adding these trinomials we get
(x³ + 2x² + 4) + (2x³ + x² - 3) = 0
3x³ + 3x² + 1 = 0
Which proves that sum of two trinomials is ALWAYS a trinomial.
So the answer is True.

What is the area of the triangle in the diagram?
Answer:
Option A is the answer.
Step-by-step explanation:
The area of the triangle is given as :
[tex]A=\frac{1}{2}\times base\times height[/tex]
Base will be given by :
[tex]\sqrt{(x1-0)^{2}+(y1-0)^{2}}[/tex]
= [tex]\sqrt{x1^{2}+y1^{2}}[/tex]
Similarly the height will be given by:
[tex]\sqrt{(x2-0)^{2}+(y2-0)^{2}}[/tex]
= [tex]\sqrt{x2^{2}+y2^{2}}[/tex]
Now, putting these dimensions in the formula we get:
[tex]\frac{1}{2}\times \sqrt{(x1^{2}+y1^{2})(x2^{2}+y2^{2})}[/tex]
Therefore, option A is the answer.

Ysidra paints a room that has 400 square feet of wall space in 2 and a half hours. at this rate, how long will it take her to paint a room that has 720 square feet of wall space?
The time taken to paint a room which has a wall space of 720 feet² is equal to [tex]4\frac{1}{2}[/tex] hours.
What is the unitary method ?
The unitary method is a method in which you find the value of one unit and then the value of required no. of units.
It is given that room is painted that has wall space of 400 feet². The time taken to paint this space is 2 and half hours.
So , the wall space painted per hour will be :
= 400 ÷ [tex]2\frac{1}{2}[/tex]
= 400 ÷ [tex]\frac{5}{2}[/tex]
= 400 × [tex]\frac{2}{5}[/tex]
= 160 square feet per hour
We have to find out the time taken to paint a room which has a wall space of 720 feet². So , this will be calculated by dividing 720 square feet wall space by the per hour painted wall space that is equal to:
= 720 / 160
= 4.5 hours
or
= [tex]4\frac{1}{2}[/tex] hours
Therefore , the time taken to paint a room which has a wall space of 720 feet² is equal to [tex]4\frac{1}{2}[/tex] hours.

A problem states: " there are 3 more baseballs than bats in a dugout. There are 15 bats and baseballs in the dugout in all. How many bats are in the dugout?" Let b represent the number of bats. Which expression represents the situation?
Answer:
The required equation is 2b+3=15.
Number of bats = 6
Number of baseballs = 9
Step-by-step explanation:
Let b be the number of bats.
It is given that there are 3 more baseballs than bats in a dugout.
Number of baseballs = b + 3
Number of bats and baseballs in the dugout in all is
[tex]Total=b+(b+3)[/tex]
[tex]Total=(b+b)+3[/tex]
[tex]Total=2b+3[/tex]
There are 15 bats and baseballs in the dugout in all.
[tex]2b+3=15[/tex]
The required equation is 2b+3=15.
Subtract 3 from both sides.
[tex]2b=15-3[/tex]
[tex]2b=12[/tex]
Divide both sides by 2.
[tex]b=6[/tex]
The value of b is 6. So, the number of bats is 6 and number of baseballs is 6+3=9.

What conjecture can you make about the twentieth term in the pattern A, B, A, C, A, B, A, C?
Answer:
c
Step-by-step explanation:
ABACABACABACABACABAC
The pattern A, B, A, C repeats every four terms. Dividing the term number (20) by the length of the repeating sequence (4) yields 5 with no remainder, indicating the twentieth term will be the same as the fourth term - which is 'C'.
Explanation:The given pattern A, B, A, C, A, B, A, C is a repeating sequence that occurs in sets of four (A, B, A, C). To ascertain the twentieth term in this pattern, divide the term number by the length of the repeating sequence. That would be 20 divided by 4, which equals 5 with no remainder. That suggests the twentieth term will be the same as the fourth term in the sequence, which is C.
