solve some algebra problems using the properties of equality...
pls help i’m horrifyingly bad a math i understand nothing :(((
Answer:
a. Property 1
b. Property 2
Step-by-step explanation:
In this case, what we will do is say the properties of the equations, which are 4, the following:
Property 1: When a number is added or subtracted to both sides of equality, equality remains.
Property 2: When multiplied or divided by the same number, other than zero, on both sides of equality, equality remains.
Property 3: When both members of equality are raised to a nonzero power, equality remains.
Property 4: When the same root is extracted, on both sides of the equality, equality remains.
In other words, property 1 is used in part a and property 2 is used in part b.

If bc = 11 cm and tan ABC= 8 over 11 what is the area of angle ABC
Answer:
The Answer is D
Step-by-step explanation:
The area of the given triangle would be 44 cm². Hence, option (d) is true.
Used the formula for the area of a triangle,
Area of triangle = 1/2 × Base × Height
Given that,
The triangle ABC is shown in the image.
Here, BC = 11 cm
Tan ∠ABC = 8/11
Used the formula for tan x,
tan x = AC/BC
8/11 = x/11
x = 8 cm
Since, Area of triangle = 1/2 × Base × Height
Base = 8 cm
Height = 11 cm
So, we get;
A = 1/2 × 8 × 11
A = 44 cm²

Hilda plans to display in a clear cube the needle Betsy Ross used to sew the first American flag. The needle will fit exactly as the diagonal of the cube.
If the side length of the clear cube is 6 inches, and the diagonal of a face of the cube is 6
inches, what is the length of the needle
Answer: the length of the needle is 8.49 inches.
Step-by-step explanation:
The diagram of the clear cube is shown in the attached photo. From the diagram, a right angle triangle ABC is formed.
BC represents the diagonal of a face of the cube.
AB represents the the side length of the clear cube.
AB = h represents the length of the needle
To determine AB, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
Therefore
AB² = 6² + 6² = 72
AB = √72
AB = 8.49

4. A cylinder has a height of 7 cm and a base with a diameter of 10 cm. Determine the volume, in cubic centimeters, of the cylinder in terms of pi
Answer:
[tex]549.8cm^{3}[/tex]
Step-by-step explanation
identify the variables - h = 7 d = 10
radius is half of the diameter - r = 5
V = πr2h use volume of a cylinder formula
V = π(5) (7) substitute variables into formula
V = 549.778714378 multiply
V = [tex]549.8cm^{3}[/tex] round to the nearest tenths place
Final answer:
To find the volume of a cylinder with a given height and base diameter, you need to use the formula V = πr²h. In this case, with a base diameter of 10 cm and a height of 7 cm, the volume is 275.75 cm³.
Explanation:
In this case, we are dealing with the volume of a cylinder with a given height and base diameter. The formula to find the volume of a cylinder is V = πr²h, where r is the radius and h is the height.
Given the base diameter of 10 cm, the radius (r) is half of the diameter, so r = 5 cm. Plugging in the values, we get V = 3.142 × (5 cm)² × 7 cm = 275.75 cm³.
Over the course of the semester, Donnie's eight test scores averaged a 76. He looked through his notebook, but he could only find seven of the tests. The test scores he has in his notebook are 71, 92, 87, 75, 64, 70, 83. What score did Donnie make on the test that is missing from his notebook?
A) 62
B) 66
C) 72
D) 77
E) 82
Donnie's average test score is 76 for all eight tests. The sum of his seven known test scores is 542. To find the missing score, subtracting this sum from the sum of all eight scores gives a missing test score of 66.
The correct answer is option B.
To find Donnie's score on the missing eighth test, we can use the fact that the average of all eight test scores is 76.
The sum of the eight test scores is 8 * 76 = 608 (since the average is calculated by summing all the scores and dividing by the number of scores).
Now, we know the sum of the seven test scores in his notebook:
71 + 92 + 87 + 75 + 64 + 70 + 83 = 542
To find the missing score, subtract the sum of the known scores from the sum of all eight scores:
608 - 542 = 66
So, Donnie's score on the missing eighth test is 66.
The correct answer is: B) 66

Find the probability that a randomly selected student prefers dogs or is female enter answer as a fraction or decimal
To find the probability that a randomly selected student prefers dogs or is female, we need to add the probabilities of these two events. If we assume that these events are independent, we can estimate the probability by multiplying the probabilities of each event.
Explanation:To find the probability that a randomly selected student prefers dogs or is female, we need to add the probabilities of these two events. Let's say the probability of a student preferring dogs is P(D) and the probability of a student being female is P(F). Then, the probability that a student prefers dogs or is female, P(D or F), is given by P(D or F) = P(D) + P(F) - P(D and F).
Since we don't have the individual probabilities P(D) and P(F), we can't calculate the exact probability. However, if we assume that these events are independent, we can estimate the probability by multiplying the probabilities of each event.
For example, if the probability of a student preferring dogs is 0.4 and the probability of a student being female is 0.6, then the estimated probability that a randomly selected student prefers dogs or is female would be 0.4 + 0.6 = 1.

Help me answer this please : The new cost of an iPhone 11 is $700. You decide to put this on your credit
card that earns 9% (0.09). When the bill comes in you pay off $200,
meaning you still owe $500. How much interest will you be charged? And what will your new total bill be?
Answer:
No I will never ever help you
To calculate the interest charged on the credit card, subtract the amount paid off from the new cost of the iPhone 11 and multiply it by the interest rate and time. The interest charged is $45. The new total bill will be $545.
Explanation:To calculate the amount of interest charged on the credit card, we need to find the difference between the new cost of the iPhone 11 ($700) and the amount you paid off ($200). This difference will be the initial principal amount on which interest is charged.
Interest is calculated using the formula: interest = principal x rate x time. In this case, the principal is $500 (the remaining amount owed), the rate is 0.09 (9% as a decimal), and the time is 1 year since the interest is calculated annually for credit cards.
Using this information, we can calculate the interest charged: interest = $500 x 0.09 x 1 = $45.
To find the new total bill, we add the interest charged to the remaining amount owed: new total bill = $500 + $45 = $545.
