To know if 2 triangles are similar, we would need at least 2 angles, why?
Since a triangle has 3 angles, and those angles add up to 180°, we can easily determine the third angle.
Example: If 2 angles of a triangle were 13 and 97, we would know that 13 + 97 = 110, then 180° - 110° = 70°, so the missing angle is worth 70°.

The height of a ball in feet is modeled by
[tex]y = - 16x {}^{2} + 72x[/tex]
where X is the time in seconds after the ball is hit. How long is the ball in the air?
(May I also get steps on how to solve these kind of questions please?)
The value of time of the ball in the air is,
⇒ 4.5 seconds
What is Quadratic equation?An algebraic equation with the second degree of the variable is called an Quadratic equation.
We have to given that;
The height of a ball in feet is modeled by the equation,
y = - 16x² + 72x
where, x is the time in seconds after the ball is hit.
Hence, For time of the ball in the air, we can plug y = 0 in above equation.
y = - 16x² + 72x
0 = - 16x² + 72x
Solve for x;
- 16x² + 72x = 0
- 4x (4x - 18) = 0
This gives,
4x = 18
x = 18/4
x = 4.5 seconds
Thus, The value of time of the ball in the air is,
⇒ 4.5 seconds

Lara solved an equation incorrectly, as shown below:
Step 1: 2x = 18
Step 2: x = 18 − 2
Step 3: x = 16
Which statement best explains why Step 2 is incorrect in Lara's solution?
A) She did not divide 18 by 2.
B)She did not add 2 to 18.
C)She did not multiply 18 by 2.
D) She did not multiply 18 two times.
We have been given the steps to solve the equation as
Step 1: 2x = 18
Step 2: x = 18 − 2
Step 3: x = 16
There is an error in step 2.
We have [tex]2x=18[/tex]
x is in multiplication with 2. So in order to get rid of 2 from the left hand side, we perform opposite operation of multiplication i.e. division.
So we must divide both sides by 2.
Therefore, A is the correct option.
A) She did not divide 18 by 2.

Deborah is planting a rectangular garden. The garden is 15.25 feet long and 12.5 feet wide.
The formula for the area of a rectangle is A=bh.
What is the area of the garden?
Enter your answer as a decimal in the box.
Answer: [tex]190.625\text{ feet}^2[/tex]
Step-by-step explanation:
Given: Deborah is planting a rectangular garden.
The breadth of the garden (b)= 12.5 feet
The length of the garden (h)= 15.25
The formula for the area of a rectangle is given by :-
[tex]A=bh\\\\\Rightarrow\ A=12.5\times15.25\\\\\Rightarrow\ A=190.625\text{ feet}^2[/tex]
Therefore, the area of the garden = [tex]190.625\text{ feet}^2[/tex]
Can you help me list the following stocks and bonds in order from highest default risk to lowest default risk?
-A municipal bond in a city with a population of 150,000
-A common stock in a company under federal investigation
-A preferred stock in a 150-year old firm with good business practices
From highest to lowest default risk, the investments would likely be ranked as follows: common stock in a company under federal investigation, a municipal bond from a relatively small city, and preferred stock in a stable, long-established firm.
Explanation:The default risk of a financial investment is the likelihood that the issuer of the instrument will be unable to meet their obligations, thereby causing a default. From the highest to lowest default risk, the list would likely be:
Common stock in a company currently under federal investigation: This company has the highest default risk because the investigation could lead to penalties, disruptions in its business, or damage to its reputation.A municipal bond from a city with a population of 150,000: Though generally considered safe, these bonds can still go into default. The default risk here is lower than the stock under investigation because municipal bonds are backed by the taxes and revenue of the municipality, making them more stable than corporations which are dependent on their business performance.A preferred stock in a 150-year old firm with good business practices: This has the lowest default risk. Preferred stocks have a lower risk than common stocks because they receive dividends before common stock and have a higher claim on the assets in case of bankruptcy. The age of the firm and its good business practices also suggest stability and reduced risk. Learn more about Default Risk here:https://brainly.com/question/34906573

A spinner that has 5 areas of equal size, blue, red, green, yellow, and purple, is spun 25 times. The results are shown in the table. Are all outcomes equally likely according to the results of the experiment?
Answer:
The answer is D.) No its seems more likely to spin a blue or red than a green or a yellow
Step-by-step explanation:
No, it seems more likely to spin a blue or red than a green or yellow. According to the probability model, red and blue are landed on more often.
No, all outcomes equally likely according to the results of the experiment seems more likely to spin a blue or red than a green or a yellow
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
Given , spinner that has 5 areas of equal size, blue, red, green, yellow, and purple, is spun 25 times.
The results are shown in the table.
Color Frequency
Red 18
Blue 11
Green 8
Yellow 4
Purple 19
Total spin recorded = 25
Probability that the next spin will land on red or green or purple will be P(A∪BC) = P(A) + P(B) + P(C)
P(A∪BC) = 0.3 + 0.134 + 0.32 =0.754
= 75%
No, all outcomes equally likely according to the results of the experiment seems more likely to spin a blue or red than a green or a yellow

Write an equation in standard form for the line whose slope is undefined and and passes through (-6,4).
The equation represents a vertical line passing through the point (-6, 4) is x= -6.
When the slope is undefined, it means that the line is vertical.
In this case, the line passes through the point (-6, 4).
A vertical line has the equation of the form x = k, where k is a constant. Since the line passes through (-6, 4), the equation of the line in standard form is:
x = -6
