Solve For The Value Of V.

Answers

Answer 1

Answer:

V=14

Step-by-step explanation:

Well its a supplementary angle if you add everything together.

We know theres a 90 degrees angle and a 34 degree angle.

90+34=124

124+4v=180

Since if you add everything up its a straight line

Solve the equation normally

56=4v

14=v

Brad paid for a book that cost $13.40 with a $20 bill. What is the least combination of coins and bills that can be used to make his change? What are two other different combinations of coins and bills that can be used to make the change?

Answers

Answer:

First combination: One $5 bill, one $1 bill, two quarters and one dime.

Second combination: One $5 bill, one $1 bill, two quarters and two nickles.

Step-by-step explanation:

I highly suggest reading it to make sure you understand it

Okay so for this one you're going to want to do 20.00-13.40. The answer to that is 6.60

So we have to work with $6.60

Now lets think of the obvious/easiest.

A $5 bill is going to be our best friend in this.

We have to do

6.60-5.00=x

(Don't freak out about x, it's just our place marker!!)

The reason we do 5.00 is because that's what $5 is.

So let's solve now.

6.60-5.00=1.60

So x=1.60

But you don't have to worry about x, I'm just explaining it from before.

So we have to keep in mind that we used one $5 bill. Now let's use one $1 dollar bill.

1.60-1.00=0.60

So now we only have to figure out how to get 60 cents from any of the coins.

A quarter is 25 cents so lets use two of those

25+25=50

60=50=10

Lets recap on everything we've used so far.

We've used one $5 bill, one $1 bill, and two quarters.

Now we're going to add a dime to the mix.

A dime is worth 10 cents.

So for the first combination we used: One $5 bill, one $1 bill, two quarters and one dime.

Now our second combination is going to be really easy.

We can use almost everything the exact same, we're only going to switch up the dime part.

1 dime = 2 nickles

Nickles are worth 5 cents

So we take out the dime and replace it with two nickles.

So for the second combination we use: One $5 bill, one $1 bill, two quarters and two nickles.

What is the volume of the cylinder and i need how you got the answer plz. Thank you

Answers

Answer:

471.24 inches is the volume of the cylinder.

Basically, since the diameter of the cylinder is 10 inches the radius will be 5 inches.

The formula to figure out the volume of a cylinder is V=πr2h.

So using that formula the volume of the cylinder is 471.24 inches.  

Multiply 150 by the substitute your teacher instructed you to use for Pi. The answer will vary, but should be around 471.

V = Pi*R^2*H
V = Pi*5^2*6
V = Pi*25*6
V = Pi*150

Answers

Answer:

125-5x^2

this is the answer

Answer:

-5x^2+125

Step-by-step explanation:

You need to go step-by-step here. I would actually prefer to multiply by 5 at the end, because it's easier that way. (You can multiply the terms in any order you want, though.)

So first, multiply (5-x)(5+x). This is a special product: (a-b)(a+b)=a^2-b^2, so:

(5-x)(5+x)=5^2-x^2=25-x^2

But even if you don't know that special product, you can multiply it out. Rewrite (5-x)(5+x) as 5(5+x)-x(5+x).

 5(5+x)-x(5+x)

=25+5x-(5x+x^2)

=25+5x-5x-x^2

=25+0x-x^2

=25-x^2

As you can see, the result is the same regardless of you get it. Now multiply that by 5 to get 125-5x^2, or in standard form, -5x^2+125.

Hope I could help you!

Tyrone is working with two other students to build a border around the school’s triangular garden. Each student brought in one side of the border, but they all used different units to measure the side lengths. The first side is 312 inches long, the second side is 20 feet long, and the third side is 12 yards long. If the measurements need to be in feet, will the three border pieces make a right triangle?

Convert the first side into feet using a proportion.

Answers

Answer:

NO, the these three border pieces will not make a right triangle

Step-by-step explanation:

Perform the necessary conversions:

1.  312 in converts to

      312 in       1 ft

     ----------- * ------- = 26 ft

        12 in         1

2.  20 ft

3.  12 yd converts to

         12 yd         3 ft

       ------------- * --------- = 36 ft

            1 yd             1

So the three different side lengths are 26 ft, 20 ft and 36 ft.

For the three pieces to make a right triangle, these measurements must satisfy the Pythagorean Theorem:

26² + 20² = 36², or 1296

676 + 400 = 1076

The Theorem is NOT satisfied, and so NO, the these three border pieces will not make a right triangle.

Part A: Write a list of 6 ordered pairs to show the height of the candle in inches (y) as a function of time in hours (x) from the first hour after it started burning. For example, the point (0, 6) would represent a height of 6 inches after 0 hours. Explain how you obtained the ordered pairs. (5 points)

Part B: Is this relation a function? Justify your answer using the list of ordered pairs you created in Part A. (2 points)

  B. is a function

  C. is a function

Step-by-step explanation:

Both relations are functions.

A relation is NOT a function if the same input value maps to two different output values. Virtually any relation involving time as an input will be single-valued: a measure can only have one value at any given time (ignoring quantum physics).

__

A: If height decreases 1/2 inch per hour, then some ordered pairs could be ...

  (hours, inches) = (0, 6), (1, 5.5), (2, 5), (3, 4.5), (4, 4), (5, 3.5)

For each additional hour, 0.5 inches was subtracted from height.

__

B: There is only one output for each input, so the relation is a function.

__

C: Yes, the relation is still a function. There is still only one output value for each input value.

To pass her test, Tori needs to answer at least 65% of the questions correct. If there were 60
questions and she got 42 correct, did she pass? All work MUST be shown to justify your
answer.

Answers

1) change 65% to a decimal = .65

2) .65 • 60 = 37.2 questions need to be right

3) since she got 42 correct, that is greater than 37.2, so she passed.

OR

1) 42/60 = 0.7

2) 0.7 to a percent = 70%

3) since she got a 70% on the test, she passed.

Step-by-step explanation:

To obtain score of 80% on entire exam means the student have to answer

(80/100)×80 = 64 correct answers

Student have already answered 75% of the first 60 questions correctly meaning

(75/100)×60=45 correct answers from first 60 questions

Remaining correct answers s/he have to answer

64-45=19

So from remaining 20 questions s/he have to answer 19 correct questions that is

20 × (x/100) = 19

x = 19 ×(100/20)

x = 95%

Part B: What are the initial value and slope of the graph and what do they represent?

Answers

Step-by-step explanation:The slope of AB and BC are the same.

The initial value is 60 m and the slope is 40 m/min.

Step-by-step explanation:

The graph shows the depth, y, in meters, of a shark from the surface of an ocean for a certain amount of time, x, in minutes.

See the graph attached.

Part A : If we consider two right triangles one Δ ABD and Δ BCE, where D(2,100) and E(1,60) points.

Now, those two triangles are similar and hence the slope of line segment AB will be .

Again, the slope of the line segment BC will be

Hence,  and the slope of AB and BC are the same. (Answer)

Part B : From the graph, it is clear that the initial value of the graph is 60 m and it represents that initial position of the shark i.e. at t = 0 min, the shark was at a depth of 60 m from the water surface.

The slope of the graph is 40 means the rate of change of distance from the Ocean surface of the shark with respect to time in minutes will be 40 m per min. (Answer)

Exact solutions for divide-and-conquer recurrence relations. Expand the terms of each recurrence relation in order to obtain an exact solution for T(n). Your solution should include all the constants in the expression for T(n), and not just the asymptotic growth of the function T(n). You can assume that the value of n, the input to the function T, is a power of 3. That is, n = 3k for some integer k. (a) T(n) = 3T(n/3) + 5n T(1) = 5 (b) T(n) = 3T(n/3) + 5n T(1) = 5 Solution At each level, expand the expression for T, using the recurrence relation. Start with T(n) at level 0. Replace T(n) by 5n at level 0 and add three T(n/3) terms at level 1. Then replace each T(n/3) at level 1 with 5 (n/3). For each term at level 1, add three T(n/9) terms at level 2. Continue with the expansion until level L, where n/3 = 1. There will be 3 terms at level L, each of value T(1). Use the initial value T(n) and replace each T(1) terms at level L with the number 5. There are a total of L+1 levels. Since n/3 = 1, then n = 3 and by the definition of logarithms, L = log3 n. The value of T(n) is the sum of all the terms at each level. At level j, there are 3 terms, each with value 5 (n/3). Note that at level L, there are 3 terms, each with value 5 = 5 (n/34), because n/34 = 1. The total value of all the terms at levelj is 2 3 3.5.
