A building contractor has a piece of crown molding that is 48 1/2 inches long he cuts off one piece measuring 10 1/4 inches and another piece 2 feet 1/8 inch how much does he have left

Answers

Well, lets first start with 48 1/2 - 10 1/4. We can turn 48 1/2 to 48 2/4. 48 2/4 - 10 1/4 = 38 1/4. Next, we have to convert 2 feet and 1/8 inches to inches, which would be 24 1/8 inches. Turn 38 1/4 to 38 2/8. Last of all, 38 2/8 - 24 1/8 = 14 1/8. He has 14 1/8 inches left.

Given:
Velocity = 5 km/h after 1 hour
Velocity = 3 km/h after 2 hours

Part A.
Let 
v = a + bt
where
v = velocity, km/h

Because v=5 when t=1, therefore
a + b = 5             (1)
Because v=3 when t=2, therefore
a + 2b = 3            (2)
Subtract (1) from (2).

If Zayed creates the greatest number of identical packages possible, how many pencils will be in each package?

Answers

Answer:

Step-by-step explanation:

We are given Zayed is helping his classmates get ready for their math test by making them identical packages of pencils and calculators.

Number of pencils=72

Number of calculators=24

If Zayed creates the greatest number of identical packages

Then , we find GCF of 72 and 24

A soccer team played 160 games and won 65 percent of them. How many games did it win ? Please show work

Answers

To find the percent of games the soccer team won, you would do 160 multiplied by 0.65, because if you were to convert the 65% into a decimal, you would get 0.65. Notice the key word, "of". This refers to multiplication. So when doing 160*0.65, you get 104 games won. Therefore the soccer team won 104 of their games.

Hope this helps! :D Feel free to ask more questions, or ask me questions about my explanation.

The number of games won is 104.

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Number of games = 160

Percentage of games won = 65%

Now,

The number of games won.

= 65% of 160

= 65/100 x 160

= 104

Thus,

The number of games won is 104.

How do you convert from a radical expression to a rational exponent?

Im just a little confused so if someone could explain this to me, thatd be great!

Answers

 The denominator of the raised fraction is what goes on the outside of the square root. So if you had 2 raised to 1/3, you'd put the 3 raised outside to the left of the radical and the 2 inside. They give the same answer, so if you know one, you can always play with the other until you get the same answer. My teacher told us in Calculus a funny/weird way to remember it is the "bottom (of the raised fraction) goes in the crack (of the radical)." Does this help??
Final answer:

To convert a radical expression to a rational exponent, identify the root index of the radical as this will be the denominator of the rational exponent. The base remains unchanged. The rational exponent is 1 over the root index.

Explanation:

To convert a radical expression to a rational exponent, you need to understand the connection between them. In mathematics, the 'nth root of a' can be written as a radical expression or as a to the power of 1/n, which is the rational exponent form.

For example, if we have √a (square root of a), which is a radical expression, it can be written as a^(1/2) in rational exponent form. Similarly, the cube root of a (3√a) translates to a^(1/3).

During one day on the stock market, an investor lost $2500 on one stock, but gained $1700 on another. At the end of trading that day, the investor's holdings were worth $52500. What were they worth when the market closed that day?

Answers

Let x and y represent the two holdings.

Before trading day:
The holdings were worth x + y.

At the end of the trading day:
Holding x  changes to x - 2500 because of loss.
Holding y changes to y + 1700 because of gain.

The holdings are worth $52500 at the end of trading, therefore
(x - 2500) + (y + 1700) = 52500
x + y - 800 = 52500
x + y = 53300

Answer:
Before the trading day, the holdings were worth $53,300.
At the end of the trading day, the holdings were worth $52,500.

what number is greater than 535 but rounded to the nearest 100 is 500?
which one?

523 535 545 550

Answers

Answer: 545

This is because in rounding, numbers are rounded up when they are past the halfway mark, but down when they are below the halfway mark. If the number is exactly the halfway point, then it is also usually rounded up.
In this case, the halfway point is 550. 545 is less than 550, so if it is rounded to the nearest 100, it is rounded down to 500.
545 because the 45 is more than 35 and the answer is still 500 when rounded off

Which of the following approaches can be used to construct a parallelogram? Select one: a. Measure equal segments on parallel lines, then join the endpoints of these segments. b. Construct two congruent angles, then bisect them. c. Construct the perpendicular bisector of a segment, then bisect two of the right angles. d. Construct two perpendiculars to a parallel line.

Answers

Final answer:

The correct approach to constructing a parallelogram is to measure equal segments on parallel lines and then join the endpoints of these segments, which ensures opposite sides are equal and parallel.

Explanation:

The student has asked which of the following approaches can be used to construct a parallelogram. The correct approach is Measure equal segments on parallel lines, then join the endpoints of these segments, which corresponds to option a. This method utilizes the properties of parallelograms, where opposite sides are equal in length and parallel to each other. The Euclidean Geometry postulates that relate to this method include E1 Two points determine a line, E2 Line segments can be extended, and the Parallel postulate: Given a line and a point not on the line, no more than one line can be drawn through the point and parallel to the given line.

To construct a parallelogram, you can follow these simplified steps:

Select any two parallel lines.

Measure and mark equal length segments on each of the lines.

Join the corresponding endpoints of these segments to form the parallelogram.

A construction company was contracted to build a cylindrical storage tank with a diameter of 48 feet and height of 25 feet. Just before construction was to begin, it was learned that a new law allows tanks to be a maximum of 9 feet in height. If the tank is redesigned to meet the law, but has the same volume, what is its new diameter?

Answers

v=hpir^2
d/2=r

so, at first, diameter is 48ft
48/2=24ft is radius
height is 25ft

so volume=25pi24^2 or 14400pi cubic feet

max of 9ft

if we want 9ft height
find r
hmm

14400pi=9pir^2
divide both sides by 9pi
1600=r^2
sqrt both sides
40=r
2r=d
2(40)=80=d

the new diameter is 80ft

and on a graph

Answers

checking all that apply the correct answers would be A B and C

The correct answers are:

A) 1 ≥ 2x ; B) 6x ≥ 3 + 8x – 4 ; and .5 shaded to the left

Explanation:

Our inequality given is 6x ≥ 3 + 4(2x - 1). First we use the distributive property:

6x ≥ 3 + 4(2x) + 4(-1)

6x ≥ 3 + 8x - 4

This means A is correct.

Next we can subtract 8x from each side:

6x-8x ≥ 3+8x-4-8x

-2x ≥ 3-4

-2x ≥ -1

Divide both sides by -1 (remember to flip the inequality symbol):

-2x/-1 ≥ -1/-1

2x ≤ 1

This can also be written as 1 ≥ 2x, so B is correct.

To finish solving this, divide both sides by 2:

2x/2 ≤ 1/2

x ≤ 0.5

To graph this, we circle 0.5 and fill it in (since it is less than or equal to), and shade to the left (since it is less than).
