The pair of angles that are vertical are <TRS and <VRW.
Determining vertical anglesTo calculate vertical angles, take the following actions:
Recognize the intersecting lines: Vertical angles are created when two lines cross.
Find the common vertex: The point where the two lines join is the common vertex for vertical angles.
Recognize the pairs of opposite angles: Two pairs of opposite angles cross the intersection point to generate vertical angles.
Hence the pair of angles that are vertical are <TRS and <VRW.

A cube has a side of 5 cm. it has a mass of 250 grams. the density of the cube is
The density of the cube is calculated to be 2 g/cm³ by dividing the mass (250 grams) by the volume of the cube (125 cm³).
Explanation:To calculate the density of a substance, you divide its mass by its volume. In the given problem, the cube has a mass of 250 grams and each side of the cube is 5 cm. The volume of a cube is calculated by taking the cube of the side length, which in this case is 5^3 = 125 cm³.
By substituting the given mass and computed volume in the formula, we find that the density of the cube is 250 grams ÷ 125 cm³ = 2 g/cm³.

Martha will be entering high school in a couple of years. Which steps should she take to ensure she has money to pay for college? Check all that apply. She should start or add to a college savings account so it can grow with deposits and earned interest. She should ask her parents if they have a college savings account set up for her. She should work to maintain high grades throughout school so she can qualify for scholarships. She should get involved in extracurricular activities like clubs and sports so she can discover what she enjoys and qualify for scholarships. She should fill out the FAFSA immediately so she does not miss grants or scholarships she qualifies for. She should ask all her friends and neighbors to contribute to her college savings account so it will grow faster.
Martha can ensure she has money to pay for college by starting or adding to a college savings account, maintaining high grades, getting involved in extracurricular activities, and filling out the FAFSA immediately.
Explanation:Martha can take the following steps to ensure she has money to pay for college:
Start or add to a college savings account: By saving money early, Martha can let it grow with deposits and earn interest.Work towards maintaining high grades: This will help her qualify for scholarships that can assist in paying for college.Get involved in extracurricular activities: Participating in clubs and sports can help Martha discover what she enjoys and also qualify her for scholarships.Fill out the FAFSA immediately: By submitting the FAFSA, Martha can ensure that she doesn't miss out on any grants or scholarships she may qualify for.
The steps Martha should take to ensure she has money to pay for college are as follows:
1. She should start or add to a college savings account so it can grow with deposits and earned interest. This is a proactive step that allows the money to benefit from compound interest over time.
2. She should ask her parents if they have a college savings account set up for her. It's important to know if there are existing funds that can be used for her education.
3. She should work to maintain high grades throughout school so she can qualify for scholarships. Many scholarships are merit-based, and good grades are often a key criterion.
4. She should get involved in extracurricular activities like clubs and sports so she can discover what she enjoys and qualify for scholarships. Participation in these activities can make her a well-rounded candidate for scholarships that value leadership and community involvement.
5. She should fill out the FAFSA (Free Application for Federal Student Aid) when she is eligible, which is typically during her senior year of high school. This form is crucial for accessing federal grants, loans, and work-study opportunities, as well as some state and college-specific aid.
6. While asking friends and neighbors to contribute to her college savings account could potentially help the account grow faster, it is not a conventional or reliable method for funding college education. Therefore, it is not a primary step she should take.
In summary, Martha should focus on saving money, exploring existing savings, maintaining good grades, engaging in extracurricular activities, and preparing to fill out the FAFSA. These steps will help her secure funding for college through savings, scholarships, and financial aid.
Solve the triangle. A = 46°, a = 31, b = 27
To solve the given triangle with A = 46°, a = 31, and b = 27, we use the Law of Sines to first find angle B, then use the sum of angles to find angle C, and finally, use the Law of Sines again to find side c.
Explanation:To solve the triangle with the given information A = 46°, a = 31, and b = 27, we need to use the Law of Sines or the Law of Cosines. Since we have one angle and the side opposite to it (a = 31), as well as another side (b = 27), we first need to find angle B using the Law of Sines:
\frac{\sin(A)}{a} = \frac{\sin(B)}{b}
By solving for sin(B), we get:
\sin(B) = \frac{\sin(46°) * 27}{31}
Next, we calculate the value of sin(B) and then angle B. After that, we can find angle C by using the fact that the sum of angles in a triangle is 180°:
A + B + C = 180°
Once we have angle C, we can use the Law of Sines again to find side c:
\frac{\sin(C)}{c} = \frac{\sin(A)}{a}
By rearranging and solving for c, we get:
c = \frac{\sin(C) * a}{\sin(A)}
This process will give us the lengths of all sides and the measurements of all angles, thus solving the triangle.

find the value of x for the triangle or rectangle... plz help asap 4 both
The value of 'x' in a triangle is determined by using the Pythagoras theorem, while in a rectangle, it's determined by algebraic equations.
Explanation:In order to find the value of 'x' in both cases, we need to understand that two different concepts potentially apply; Pythagoras theorem for the triangle, and algebra for the rectangle. The Pythagorean theorem applies to right angle triangles and is expressed as x² + y² = h² where 'x' and 'y' are sides and 'h' is the hypotenuse. In a rectangle, to find 'x' related to an equation like y = 9 + 3x, you substitute values for 'y' and solve for 'x'. An example is given in Table A1 where we see an instance of substituting values for 'x' and then calculating what value of 'y' results. These points are then plotted on a graph.

Jermaine’s father owes $6,300 in interest at the end of a 60-month car loan at a 7% simple annual interest rate. What was the original loan amount?
Answer:
$18,000
Step-by-step explanation:
It is given that the interest amount $6,300
We will calculate the principal amount.
So we use the formula
I = prt
P = Principal amount
r = rate of interest 7% ( 0.07 )
t = time in years 60 months ( [tex]\frac{60}{12}[/tex] years )
6,300 = P × 0.07 × [tex]\frac{60}{12}[/tex]
6,300 = P × 0.07 × 5
6,300 = 0.35P
[tex]\frac{6,300}{0.35}[/tex] = P
P = $18000
The original loan amount was $18,000.
