I Doing Vertical Angles And I'm Way Too Confused To Even Understand

Answers

Answer 1

Erotically angles are opposite each other and equal the same degree.

In the image 5x and 120 are vertical angles so 5x needs to equal 120.

X = 120/5

X = 24

Answer 2

Answer:

X=24 degrees.

Step-by-step explanation:

120/5=24. You divide by 5, because the angles will be congruent, and the top angle is 5*_=120. And 5*24=120, so x=24

The bill at a restaurant is $160. You leave a 20% tip. What is your total restaurant bill, including the tip? 20 points! ​

Answers

Answer:

$192

Step-by-step explanation:

Bill: $160.00

Tip: 20%

To figure out 10%, you need to move the decimal point over to the left one place: $16.00

10%: $16.00

16 times 2= $32.00

160.00+32.00= $192.00

192


160 20% =32

160+32= 192

Change 3 5/8 into an improper fraction.

Answers

Answer:

The improper fraction 29/8 is equal to the mixed number 3 5/8.

Step-by-step explanation:

The fractions is solved and the improper fraction is A = 29/8

Given data ,

To change 3 5/8 into an improper fraction, we need to combine the whole number and the fraction part.

The fraction part, 5/8, can be expressed as an improper fraction by multiplying the whole number, 3, by the denominator of the fraction, 8, and then adding the numerator, 5. This gives us:

3 * 8 + 5 = 24 + 5 = 29

The denominator remains the same, so the improper fraction is:

A = 29/8

Therefore , the value of A = 29/8

Hence , 3 5/8 can be expressed as the improper fraction 29/8

John was adding Rational Numbers. He showed his work below. What was John's error?

Explain to John how to solve it correctly.

Adding Rational Numbers Error.

Answers

Answer:

-5 3/5

Step-by-step explanation:

John's error was in adding the whole number and fractional portions separately, the fractions must be converted to improper fractions with common denominators to be added or subtracted properly so

(-7 4/5) + (2 1/5), convert to improper fractions

-39/5 + 11/5, both fractions have common denominator so we can continue

-39 + 11 = -28, so -39/5 + 11/5 = -28/5, convert back to proper fractions

-28/5 = (-25/5) + (-3/5) = -5 3/5

3- A video game costs a retailer $24. The store marks it up 35%, what is the markup amount?
Show work:

Answers

Answer:y = 10.5

Step-by-step explanation:

First, assign a variable to each unknown value.

Let:

x = cost of the pepperoni pizza

y = cost of the plain pizza

Next, set up equations based on the word problem. We then have the following equations:

(1) 3x + 2y = 58.50

(2) 2x + 4y = 67

Equation (1) comes from the statement: "Jack paid 58.50 for 3 pepperonies and 2 plain pizzas". Equation (2), on the other hand, translates the statement: "Jill paid 67 for 2 pepperonies and 4 plain pizzas".

To solve for two unknown variables given two independent equations, eliminate one variable first. That is, multiply equation (1) to -2.

-2[3x + 2y = 58.50]

-6x -4y = -117

Then add this to equation (2):

-6x -4y = -117

2x + 4y = 67

-------------------

-4x        = -50

x = -50/-4 = 12.5

To solve for y, we use equation (2) and substitute the value of x which has been solved already.

2(12.5) + 4y = 67

y = 10.5

To summarize, they paid $12.50 for the pepperoni pizza while they paid $10.50 for the plain pizza.

c. What percentage of regular grade gasoline sells for less than $3.55 per gallon (to 1 decimal)?

%

Answers

The percentage of regular grade gasoline sells for between $3.35 and $3.55 per gallon is 64%

The percentage of regular grade gasoline sells for between $3.35 and $3.65 per gallon is 81.5%

The percentage of regular grade gasoline sells for less than $3.55 per gallon is 84%

Given :

Mean retail price is $3.45

Standard deviation is 0.10

Empirical rule states that 99.7% of data is observed in normal distribution that lies within 3 standard deviations.

68% of data lies under 1 standard deviation

95% lies under 2 standard deviations

99.7% lies under 3 standard deviations

there are 3 standard deviations on the left and right of mean . The graph is attached below

Mean is 3.45. standard deviation is 0.1

3.45+0.1=3.55

3.45-0.1=3.35

So 3.35  and 3.55 lies under first standard deviation

The percentage between $3.35 and $3.55 is 68%

3.45 +0.1+0.1=3.65

3.35 lies on 1 standard deviation on left and 2 deviations on the right of mean

So , 34+34+13.5=81.5%

The percentage between $3.35 and $3.65 is 81.5%

For gasoline sells for less than 3.55 , there are 3 standard deviation on the left of mean and 1 standard deviation on the right

0.15+2.35+13.5+34+34=84%

(I will mark brainliest) Use this equation to solve for the missing variable:

y = 8x + 12


If x = -6, y = _____

If y = 13, x = _____

Answers

Answer: x would be 1/8 and y would be -36

Step-by-step explanation:

To find put y you would plug in -6 for x. So it would be y=8(-6)+12. Then you multiply the 8 and -6 to get -48, y=-48+12. Then subtract 48 from 12 and that is -36 so y=-36. To solve for x you would plug in the y or 13 into the equation. So, 13=8x+12. Then you would have to solve. 12 minus 13 is 1 and the you are left with 1=8x then you divide 1/8 and 8x/8 and you get x=1/8. Hope this helped!

Functions:Question 5What is the y-intercept of the line whose equation is shown below?y = - 3.3 +7Select one:3-347 The objective of this task is to use Scapy to estimate the distance, in terms of number of routers, between your VM and a selected destination. This is basically what is implemented by the traceroute tool. In this task, we will write our own tool. The idea is quite straightforward: just send an packet (any type) to the destination, with its Time-To-Live (TTL) field set to 1 first. This packet will be dropped by the first router, which will send us an ICMP error message, telling us that the time-to-live has exceeded. That is how we get the IP address of the first router. We then increase our TTL field to 2, send out another packet, and get the IP address of the second router. We will repeat this procedure until our packet finally reach the destination. It should be noted that this experiment only gets an estimated result, because in theory, not all these packets take the same route (but in practice, they may within a short period of time). The code in the following shows one round in the procedure. a = IP() a.dst = 1.2.3.4 a.ttl = 3 b = ICMP() send(a/b) If you are an experienced Python programmer, you can write your tool to perform the entire procedure automatically. If you are new to Python programming, you can do it by manually changing the TTL field in each round, and record the IP address based on your observation from Wireshark. Either way is acceptable, as long as you get the result. 1592 ft18 FtA rectangular window 5 feet by 2 feet is on a rectangular wall 9 feet by 18 feet. The rest of thewall needs to be painted.
