Alex had (3x + 1) yards of silk. He then purchases (x2 + 5x + 4) packages each containing (2x + 1) yards of silk. If he uses (2x3 + 8x2 + 10x + 4) yards of silk to make a kite, how much silk remains?

Answers

Answer 1

Final answer:

To find out the amount of silk remaining, we need to subtract the amount of silk used to make the kite from the total amount of silk Alex had before purchasing the packages. After performing the calculations, we find that Alex doesn't have any silk remaining.

Explanation:

To find out how much silk remains, we need to subtract the amount of silk used to make the kite from the total amount of silk Alex had before purchasing the packages. Let's first simplify the expressions:

Total silk Alex had = 3x + 1

Total silk purchased = (x^2 + 5x + 4) × (2x + 1)

Silk used for kite = 2x^3 + 8x^2 + 10x + 4

Now, substitute the given values of x:

Total silk Alex had = 3(1500) + 1 = 4501 yards

Total silk purchased = (1500^2 + 5*1500 + 4) * (2*1500 + 1) = 22537500 yards

Silk used for kite = 2(1500^3) + 8(1500^2) + 10(1500) + 4 = 53910002004 yards

Finally, subtract the silk used for the kite from the total silk Alex had:

Silk remaining = Total silk Alex had - Silk used for kite = 4501 - 53910002004 = -53910001403 yards

Since the result is negative, it means that Alex doesn't have any silk remaining.

Measurement is ___________ when it yields the same values across repeated measurement of the same event.

Answers

The answer is reliable. A measure is assumed to have a high reliability if it yields parallel results under steady conditions. It is the characteristic of a set of test scores that relates to the quantity of accidental or random error from the measurement procedure that might be rooted in the scores. Marks that are highly reliable are precise, reproducible, and constant from one testing time to another. To be exact, if the testing method were to be repeated with a different group of test takers, fundamentally the same results would be gotten. 

A rabbit lure on a greyhound racetrack is set to travel once around the track at 50 feet per second, and then its speed is increased to 65 feet per second for the second loop around the track. If the total time it takes for the lure to go around the track twice is 184 seconds, what is the distance once around the track?

Answers

184 sec = Circumference / 50 fps + Circumference / 65 fps 
184 = 65 Circumference/3250 + 50 Circumference/3250 
184 = 115 Circumflex/3250 
598000 = 115 Circumflex 
Circumflex = 5200 ft

The equations y = -0.38x + 56.6 and y = 0.38x + 43.4 represent the percent of men and women, respectively, receiving bachelor's degrees, where x is the number of years since 1968. in approximately what year did the same percent of men and women receive bachelor's degrees?

Answers

Begin by using simultaneous equations to find the values of x and y. 

y=-0.38x+56.6
y=0.38x+43.4 

-0.38x+56.6=0.38x+43.4 
-0.38x-0.38x=-56.6+43.4 
-0.76x=-13.3 
x=-13.3/-0.76 
x=17.5 

y=0.38(17.5)+56.6
y=63.25 

Knowing that the initial year was 1968, add 17.5 years to find to find out when the same percent of men and women received a bachelor's degree. 

1968+17.5= 1985.5 

So, in the year 1985 and half, both men and women got the same number of bachelor's degrees.

What is the slope of a line that is perpendicular to the line that goes through (5,4) and (-2,-3)?

Answers

First, let us solve for the slope of the line which it intersects with:

m’ = (y2 – y1) / (x2 – x1)

m’ = (-3 – 4) / (-2 – 5)

m’ = 1

 

The slope of the perpendicular line is the negative reciprocal, therefore:

m = - 1 / m’

m = - 1 / 1

m = -1

 

So the slope of the line is -1.

what is the value for x (5x+15) (3x-3)

Answers

Final answer:

The value of x in the expression (5x+15) (3x-3) is 15x^2 + 30x - 45.

Explanation:

The expression (5x+15) (3x-3) represents the multiplication of two binomials. To find the value of x, we can use the distributive property to simplify the expression:

Multiply the terms within the first set of parentheses: 5x * 3x = 15x^2.Multiply the terms within the second set of parentheses: 5x * -3 = -15x.Multiply the terms between the parentheses: 15 * 3x = 45x.Multiply the constant terms within the parentheses: 15 * -3 = -45.

Putting it all together, we have 15x^2 - 15x + 45x - 45. Combining like terms, the expression simplifies to 15x^2 + 30x - 45.

So, the value for x in the given expression is 15x^2 + 30x - 45.

Find x if et = 3x+2 and em = 5x

Answers

Answer:

x = 6

Step-by-step explanation:

The centroid (T) always splits the lines so one side is 2/3 and the second is 1/3 of the entire median line. This can also be written as 2x + x. That being said, ET isn't equal to EM, it's only equal to 2/3 of EM so that's what you have to write.

3x + 2 = 2/3 * 5x

3x + 2 = 10/3 x

*3 (3x+2) = *3(10/3x)

9x+6 = 10x

-9x      -9x

x = 6

The value of x is 6.

The value of x.

How to find the value of x?

We know that the centroid of triangles divides it into 2:3.

Then

[tex]\begin{aligned} \dfrac{ET}{EM} &= \dfrac{2}{3} \\\\ \dfrac{3x+2}{5x} &= \dfrac{2}{3} \\\\ 3x+2 &= \dfrac{2}{3} * 5x \\\\ 3x+2 &= \dfrac{10x}{3} \\\\ 3x - \dfrac{10x}{3} &=-2\\\\ \dfrac{-x}{3} &= -2 \\\\ x &= 6\end{aligned}[/tex]

Hence the value of x is 6.

Thus the value of x is 6.

Solve x + 9 = 18 - 2x

Answers

Add 2x to both sides,
3x+9=18
Subtract 9 from both sides. 3x=9
Divide both sides by 3. 
x=3

The solution to the equation x + 9 = 18 - 2x is x = 3.

What is the solution to the equation?

Given the equation in the question:

x + 9 = 18 - 2x

To solve the equation x + 9 = 18 - 2x, first, collect and combine the x terms on one side of the equation and the constant terms on the other side:

x + 9 = 18 - 2x

Add 2x to both sides of the equation:

x + 2x + 9 = 18 - 2x + 2x

x + 2x + 9 = 18

3x + 9 = 18

Subtract 9 from both sides of the equation:

3x + 9 - 9 = 18 - 9

3x = 18 - 9

3x = 9

Isolate x by dividing both sides by 3:

x = 9/3

x = 3

Therefore, the value of x is 3.

A sealed rectangular box measuring 8 x 6 x 18 contains 864 sugar cubes, each measuring 1 x 1 x 1. How many sugar cubes are touching the box?

Answers

Final answer:

A total of 456 sugar cubes touching the box.

Explanation:

To calculate the number of sugar cubes touching the box, we must consider the cubes that lie along each face of the box without double-counting the cubes that touch corners and edges.

The box dimensions are 8 x 6 x 18 inches, and each sugar cube is 1 x 1 x 1 inch.

For the top and bottom faces (6 x 18), we have

6*18 = 108 sugar cubes touching the box on each face, totaling 216 for both the top and bottom.

For the front and back faces (8 x 18), since we must exclude the top and bottom rows, we have

(8-2) x (18-2) = 6 x 16 = 96 sugar cubes for one face and 192 for both.

For the sides (8 x 6), excluding the top and bottom rows again, we have

(8-2) x (6-2) = 6 x 4 = 24 sugar cubes on one side and 48 in total for the two sides.

Adding all these together, we get 216 (top and bottom) + 192 (front and back) + 48 (sides) = 456 sugar cubes touching the box.

Remember, this method assumes a single layer of sugar cubes is in direct contact with the inside surface of the box.
