Tell whether the angles are adjacent or vertical. Then find the value of x.
Answers
Answer:
vertical, and x is 81
Step-by-step explanation:
The angles are across first each other, which means they are the same angle. From there, set x+3 equal to 84 (x+4=84). From there solve to get x

Convert binary 11011.110 to base 10
Answers
Answer:
27.75₁₀
Step-by-step explanation:
Convert binary 11011.110 to base 10
11011.110 = 1*2^4 + 1*2^3+0*2^2 + 1*2^1 + 1* 2^0 + 1*2^-1 + 1* 2^-2 + 0
11011.110 = 16+8+0+2+1+1/2+1/4
11011.110 =27 + 3/4
11011.110 = 27.75₁₀
Hence the binary number to base 10 is 27.75₁₀

You want to park your boat at a local boat dock at 1pm but we are in a drought and you need to make sure that the water will be high enough. Your boat will get stuck if the tide is not at least 7 feet high. The high
tide is at 5:00 am and a low tide at 10:00 am. At the low tide the water depth is 4 feet and at the high tide
the water depth is at 10 feet.
1. Sketch a graph to represent the height o the water at any given time after midnight. Graph at least 2 periods of the tide cycle
2. Identify all relevant parts of the graph
3. Write 2 general equations of the function (one as a cosine function and one as a function)
4. Use 2 different mathematical methods to find the height of the tide at 12.5 hours after midnight and then verify that answer. (Discuss the role each mathematical Mathis has in answering this question)
5. Will you be able to park your boat at the time? Give a detailed explanation to support your answer

Using the method of proof by contradiction, prove that if a product of two positive real numbers is greater than 1,000,000, then at least one of the numbers is greater than 1000.
Answers
Step-by-step explanation:
To prove - Using the method of proof by contradiction, prove that if
a product of two positive real numbers is greater than
1,000,000, then at least one of the numbers is greater
than 1000.
Proof -
For a proof of contradiction , firstly we have to assume that the statement is not true.
Here given statement is - A product of two positive real numbers is greater than 1,000,000.
Let if possible, there does not exist 2 +ve integer real number such that at least one of the numbers is greater than 1000.
⇒both the number are in between 0 to 1000
Let a and b are 2 +ve real numbers.
⇒ab < 1000×1000
⇒ab < 1000000
As given,
ab > 1000000
Contradiction.
Hence proved.
If a product of two positive real numbers is greater than 1,000,000, then at least one of the numbers is greater than 1000.
Malia split up The large container of salsa that she bought equally into five balls to place around her house for the party if each bowl contained 8.5 ounces of salsa which shows the correct equation and value of X the total amount of salsa in the original container
Answers
Answer:
B. [tex] \frac{x}{5} = 8.5 [/tex]; [tex] x = 42.5 ounces [/tex]
Step-by-step explanation:
Total amount of salsa in container = x
Number of bowl the salsa is divided into = 5
Amount contained by each bowl = 8.5 ounces of salsa
Therefore:
[tex] \frac{x}{5} = 8.5 [/tex] ---› equation
Solve for x
Multiply both sides by 5
[tex] \frac{x}{5}*5 = 8.5*5 [/tex]
[tex] x = 42.5 [/tex]

A lake is 200 feet wide. Two boats start to move towards one another from opposite shores. In one minute, the first boat goes 40 feet, and the second boat goes 30 feet (they are very slow!).
Answers
Answer:
I use faction
Step-by-step explanation:
The first boat.
[tex]\frac{40 feet}{60 seconds}[/tex] ÷ 10 = [tex]\frac{4 feet}{6 seconds}[/tex]
[tex]\frac{4 feet}{6 seconds}[/tex] ÷ 2 = [tex]\frac{2 feet}{3 seconds}[/tex]
The first boat move [tex]\frac{2 feet}{3 seconds}[/tex]
The second one do the same
[tex]\frac{30 feet}{60 seconds}[/tex] ÷ 10 = [tex]\frac{3 feet}{6 seconds}[/tex]
[tex]\frac{3 feet}{6 seconds}[/tex] ÷ 2 = [tex]\frac{1.5 feet}{3 seconds}[/tex]
That is the speed of each boat.
The first boat need 50 minutes to get to the other side
2000 ÷ 2 =1000
1000 x 3 = 3000
3000 ÷ 60 = 50
The second boat need 66.6666666667 minutes to get to the other side
200 ÷1.5 = 1333.33333333
1333.33333333 x 3 = 4000
4000 ÷ 60 = 66.6666666667

Answers
The interquartile range of Victor's lemonade sale is A = 7
What in Interquartile Range ( IQR )?The distance between the upper and lower quartiles is known as the interquartile range. Half of the interquartile range corresponds to the semi-interquartile range. Finding the values of the quartiles in a small data set is straightforward.
The spread of the data, or statistical dispersion, is measured by the interquartile range. The middle 50%, fourth spread, or H-spread are further names for the IQR. It is described as the spread between the data's 75th and 25th percentiles.
Given data ,
Let the interquartile range of sales of Victor's lemonade be A
Now , the equation will be
Let the 75th percentile data = 29
Let the 25th percentile data be = 22
Now , the IQR is calculated by spread between the data's 75th and 25th percentiles
On simplifying , we get
The IQR = 29 - 22 = 7
Hence , the interquartile range is 7
