Two angles of a triangle have the same measure and the third one is 15 degrees greater than the measure of each of the other two. Find the measure of the LARGEST angle in the triangle.

The LARGEST angle has a measure of _____ degrees.

Answers

Answer 1

Answer:

70°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

let the equal angles be x then the third angle = x + 15

Sum the 3 angle and equate to 180

x + x + x + 15 = 180

3x + 15 = 180 ( subtract 15 from both sides )

3x  = 165 ( divide both sides by 3 )

x = 55

Hence

The largest angle = x + 15 = 55 + 15 = 70°

the ride in minutes.
(a) What is the height of the last passenger at the moment of the power outage? Verity your answer by
evaluating the sine function model.
(b) Will the last passenger to board the ride need to wait in order to exit the ride? Explain.

Answers

Answer:

I will assume

h = 82.5 sin (3 pi (t+0.5) )+97.5 , (you had no equation and no h)

so when t = 6

h = 82.5 sin (3π(6.5)) + 97.5

= 82.5(-1) + 97.5 = 15

check: period = 2π/(3π) = 2/3 minutes (that is a fast ride considering how huge it is)

So 6 ÷(2/3) = 9 , at the 6 minute mark, the last passenger has just completed 9 rotations.

the min height of the basket is -82.5 + 97.5 = 15

( the min value of 82.5 sin(anything) = 82.5(-1) )

so the last passenger must be at the platform level.

bicycles 14mph with no wind. Against the wind, bikes 10 mi in
the same time it takes to bike 20 mi with the wind. What is the speed of
the wind?​

Answers

recall your d = rt, distance = rate * time.

w = speed of the wind.

14 = speed of the bicycle without wind.

now, against the wind, the bicycle is not really going 14 mph fast, is really going "14 - w", since the wind is eroding speed from it, likewise, when the bicycle is going with the wind is not going 14 mph fast either, is really going "14 + w" due to the wind adding speed, let's say it took "t" hours against and also "t" hours with it.

[tex]\bf \begin{array}{lcccl} &\stackrel{miles}{distance}&\stackrel{mph}{rate}&\stackrel{hours}{time}\\ \cline{2-4}&\\ \textit{against the wind}&10&14-w&t\\ \textit{with the wind}&20&14+w&t \end{array}~\hfill \begin{cases} 10=(14-w)t\\ \frac{10}{14-w}=\boxed{t}\\ \cline{1-1} 20=(14+w)t \end{cases}[/tex]

The Chesapeake Bay tides vary between 4 feet and 6 feet. The tide is at its lowest point when time (t) is 0 and completes a full cycle in 12 hours. What is the amplitude, period, and midline of a function that would model this periodic phenomenon?

Amplitude = 1 foot; period = 12 hours; midline: y = 5

Amplitude = 2 feet; period = 6 hours; midline: y = 1

Amplitude = 2 feet; period = 12 hours; midline: y = 5

Answers

Answer:

Amplitude = 1 foot; period = 12 hours; midline: y = 5

Step-by-step explanation:

The Chesapeake Bay tides vary between 4 feet and 6 feet.

This means the range is

[tex]4 \leqslant f(t) \leqslant 6[/tex]

The period is the length of the interval on which the function completes one full cycle.The tide is at its lowest point when time (t) is 0 and completes a full cycle in 12 hours.

The interval is [0,12] and its length is 12, hence the period is 12.

The midline

[tex]y = \frac{min + max}{2} [/tex]

[tex]y = \frac{4 + 6}{2} = 5[/tex]

The amplitude is the distance from the midline to the peak.

The amplitude is |5-4|=|5-6|=1

The first choice is correct.

Final answer:

The amplitude of the function modeling the Chesapeake Bay tides is 1 foot, the period is 12 hours, and the midline is at y = 5 feet.

Explanation:

The amplitude of a function that models a periodic phenomenon, like the tides in this case, is half of the total variation in height. Since the tides vary between 4 feet and 6 feet, the total variation is 2 feet (6 feet - 4 feet), and thus, the amplitude is 1 foot (2 feet / 2).

The period of the function is the time it takes for the tidal cycle to repeat itself. Given that the tide completes a full cycle in 12 hours, the period of the function is 12 hours.

The midline represents the average value around which the tide oscillates. It can be found by averaging the maximum and minimum tide levels. Therefore, the midline is (4 feet + 6 feet) / 2 = 5 feet.

Considering these calculations, the correct amplitude is 1 foot, the period is 12 hours, and the midline is y = 5 feet for the function that would model the periodic phenomenon of the Chesapeake Bay tides.

In converting 7.5 pounds to ounces, what unit (omit the number) would you place
in the denominator of your ratio? Use the plural form in your answer. Remember
that there are 16 ounces in 1 pound.

Answers

Final answer:

In converting 7.5 pounds to ounces, the unit placed in the denominator of the ratio is pounds. To do the conversion, multiply the number of pounds by 16, since there are 16 ounces in one pound. Therefore, 7.5 pounds is equal to 120 ounces.

Explanation:

When converting 7.5 pounds to ounces, we start by identifying the conversion factor between these two units of weight. The unit you would place in the denominator of your ratio is pounds, since the relationship is that 1 pound is equivalent to 16 ounces. So, the conversion from pounds to ounces requires multiplying the number of pounds by 16.

Here's how you would set up your conversion:

First, write down the amount of pounds you want to convert (7.5 pounds).

Multiply this amount by 16, the number of ounces in one pound (7.5 x 16).

The product will give you the amount in ounces (7.5 x 16 = 120 ounces).

The unit in the denominator for the ratio used in this conversion is pounds, as you are starting with pounds and converting to ounces.

Write the equation 8y = 1/12 x – 0.8 in standard form. Identify A, B, and C.

Answers

Answer:

The equation is 10x - 960y = 96

A = 10 , B = -960 , C = 96

Step-by-step explanation:

* Lets explain the standard form of the linear equation

- The standard form of the linear equation is :

 AX + BY = C , where A , B , C are constant

- A is a positive integer, and B, and C are integers

- The slope of the line is -A/B

- The y-intercept is C/A

- Lets solve the problem

∵ The equation of the line is 8y = 1/12 x - 0.8

- At first multiply the equation by 12 to make the coefficient of x integer

∴ (8 × 12) y = (1/12 × 12) x - (0.8 × 12)

∴ 96y = x - 9.6

- Multiply the two sides of the equation by 10 to make 9.6 integer

∴ (96 × 10) y = (1 × 10) x - (9.6 × 10)

∴ 960y = 10x - 96

- Add the two sides by 96

∴ 960y + 96 = 10x

- Subtract 960y from both sides

∴ 96 = 10x - 960y

∴ The standard form of the equation is 10x - 960y = 96, where

  A = 10 , B = -960 , C = 96

a lottery costs $1 per ticket. the player selects a sincle letter from A to T and a single digit from 0 to 9. if both the letter and the digit match the letter and digit picked on that day, the player wins $250. what is the expected value of a lottery ticket/

Answers

Answer:  0.25 dollars (ie 25 cents)

================================================

Explanation:

The letter T is the 20th letter in the English alphabet. This means that there are 20 letters to pick from to go with the 10 single digit numbers to pick from. We have 20*10 = 200 different combinations (eg: one combination is K4).

Out of these 200 combinations, there is exactly one winning match.

The probability of winning is therefore P(W) = 1/200 = 0.005 and the probability of losing is P(L) = 1-P(W) = 1-0.005 = 0.995 where W and L represent winning and losing respectively.

The net value of winning is V(W) = 250 - 1 = 249 because the player wins $250 but they lose $1 (which is the cost of the ticket). The net value of losing is V(L) = -1, indicating the player has lost that $1 and hasn't gained any money at all.

-----------

To summarize so far:

P(W) = 0.005

P(L) = 0.995

V(W) = 249

V(L) = -1

Multiply the probability P values with the corresponding net values V, then add up the products to get the expected value:

E(X) = P(W)*V(W) + P(L)*V(L)

E(X) = 0.005*249 + 0.995*(-1)

E(X) = 0.25

The expected value is 0.25 dollars or 25 cents

This positive expected value means that the game is favored toward the player, because over the long run, the player gains an average of 25 cents each time they play. On the other side of the spectrum, the lottery company loses on average 25 cents each time. The nonzero expected value means that the game is not fair.

The correct option is 3. The possible domain and range of the function is (10, 100).

Step-by-step explanation:

It is given that a bakery's production is modeled by function f(x), where

f(x) = The number of donuts made in a day

x = The number of bags of flour needed.

The number of donuts made in a day and the number of bags of flour needed can not be a fraction value of a negative number. So, the values of x and f(x) can not defined by negative or decimal numbers.

In ordered pair (-1,15), the value of x is negative, so option 1 is incorrect.

In ordered pair (5,92.75), the value of y is in decimal, so option 2 is incorrect.

In ordered pair (10,100), both coordinates are positive integers, so option 3 is correct.

In ordered pair (-5,110.5), the value of x is negative and the value of y is in decimal, so option 4 is incorrect.

The possible domain and range of the function is (10, 100). Therefore the correct option is 3.

12 (25 + x) = x (18 + 12)

300 + 12x = 30x

300 = 18x

x = 16.7

b)

x / (7 + 2) = 3 / 2

x = 13.5

Find the quotient.
8.24 = 1.7=​

Answers

Answer:

4.847

Step-by-step explanation:

divide 8.24 by 1.7

8.24 /1.7 = 4.847

For this case we have the following operation:

[tex]\frac{8.24} {1.7}[/tex]

We must find the final result after the division.

To do this, we can use a calculator or a computer program.

We then have to do the division:

[tex]\frac{8.24} {1.7} = 4.94[/tex]

Answer:

The total ratio is given by: 4.94.

What is the surface area of the rectangular prism below?
A. 260 units
B. 612 units2
C. 800 units2
D. 689 units2

Answers

Answer:

B.612 units2

Step-by-step explanation:

To solve surface area you multiply the area of each of the faces then you add the areas together. So the equation you need to solve is 13×6+13×6+12×13+12×13+12×6+12×6

After you solve that equation the answer you should get is 612.

Answer:

612

Step-by-step explanation:

Solve 2x +5=12 answer?!

Answers

Answer:

x = 3.5

Step-by-step explanation:

To solve this you need to solve for x.

This is a two step equation so you need to first subtract 5 from itself and whatever you do to one side of the equation you have to do to the other side as well.

So 5 - 5 = 0

12 - 5 = 7

Then the equation becomes 2x = 12

Now it is a one step equation, so find the inverse operation of multiplication, which is division .

So 2 divided by 2 is 1 which also equals x by itself

7 divided by 2 equals 3.5

So x = 3.5

Answer:

[tex]\huge\boxed{x=\frac{7}{2}, x=3.5}[/tex]

Step-by-step explanation:

Subtract by 5 from both sides of equation.

[tex]\displaystyle 2x+5-5=12-5[/tex]

Simplify.

[tex]\displaystyle 12-5=7[/tex]

[tex]\displaystyle2x=7[/tex]

Divide by 2 from both sides of equation.

[tex]\displaystyle \frac{2x}{2}=\frac{7}{2}[/tex]

Simplify, to find the answer.

[tex]\displaystye x=\frac{7}{2}, x=3.5[/tex]

x=7/2 and x=3.5 is the correct answer.
