The total length of two ribbons is 13 meters. If one of the ribbons is 7 5/8 meters long, how long is the other one

Answer:

1/9 is the probability that its red chip.

Step-by-step explanation:

total chips = 14 + 10 + 12 = 36 chips

first probability = 12/36 = 1/3

second probability = 12/36 = 1/3...........total remains same, 36 as its replaced

therefore probability =  1/3 * 1/3 = 1/9

The value of x is 1.5.

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Simplification is to make something easier to do or understand and to make something less complicated.

Given

The linear equation 3.4x - 1.72 = -6.82

The value of x.

The linear equation 3.4x - 1.72 = -6.82 is given.

Then by simplification,

The first step, add 1.72 on both side

3.4x - 1.72 + 1.72 = -6.82 + 1.72

          3.4x = -5.1

The second step, Divide both sides by 3.4

          x = -5.1/3.4

          x = -1.5

Thus the value of x is -1.5.

Answer:

4321 people

Step-by-step explanation:

Since the population is modeled by exponential growth, we would need to determine the approximate growth factor by using the formula [tex]y=ab^x[/tex] where [tex]a[/tex] is the initial population, [tex]b[/tex] is the growth factor, and [tex]x[/tex] will be the number of years after 1994:

[tex]y=ab^x\\\\1519=1256b^2\\\\\frac{1519}{1256}=b^2\\\\b\approx1.0997[/tex]

Therefore, since 13 years after 1994 is 2007, then we have:

[tex]y=1256(1.0997)^x\\\\y=1256(1.0997)^{13}\\\\y\approx4321[/tex]

Therefore, the population of Amuel in 2007 was approximately 4321 people.

let's first off convert the mixed fractions to improper fractions, and then get its volume, bearing in mind that the radius is half the diameter.

Answer: B

from the first image, the opposite of B is D. so whenever its rotated somehow, D is going to fall on the opposite of B. Therefore when B is at the top, D should be at the opposite on the bottom. Thus we found our answer. B is the correct answer. others are eliminated.

Answer:

4^8

Step-by-step explanation:

If you are multiplying two bases that are the same with different exponents, the exponents get added and the base stays the same:

[tex]x^a*x^b=x^{a+b}\\\\4^3*4^5=4^{3+5}\\\\4^3*4^5=4^8[/tex]

Therefore, 4^3 * 4^5 = 4^8

Answer:

$5000

Step-by-step explanation:

x * .20 = 1000

x = 1000/.20

x = 5000

10x4a=40a

10x9=90

-8x2=-16

-8xa=-8a

40a-8=32a

90-16=74

32a+74

since we know the triangles are similar, that means we can use the corresponding sides of each for proportions

[tex]\cfrac{TU}{QR}=\cfrac{UV}{RS}\implies \cfrac{x+5}{24}=\cfrac{36}{54}\implies \cfrac{x+5}{24}=\cfrac{2}{3}\implies 3x+15=48 \\\\\\ 3x=33\implies x=\cfrac{33}{3}\implies x = 11[/tex]

now, the picture is a bit misleading, why did we pick so?

well, one triangle is named QRS, sides QR, RS and SQ

the other triangle is named TUV, sides TU, UV and VT

so you can see which side correspond with the other.

Answer:

the first one : 4/5 + 3/8

the third one : 7×sqrt(5) - sqrt(245)

the 4th one : 4×sqrt(7) × 2×sqrt(7)

Step-by-step explanation:

per definition, the set of rational numbers is the set of all integers and fractions.

the first answer is simply a prime example of fraction operation, and the result is therefore a fraction again.

the 3rd answer delivers 0, because

sqrt(245) = sqrt(49×5) = 7×sqrt(5). this is a rare occasion where an operation with a non-rational number still delivers a rational result.

the 4th answer squares the square root of 7 creating 7, which creates overall an integer and therefore rational result.

the other options contain at least one number that is not rational and will not be converted or neutralized by the operation.

and the sum and product of a rational with a non-rational number is always non-rational.

sqrt(100) + sqrt(5) = 10 + sqrt(5).

as 5 is not a square number, its square root contains an infinite number of digits after the decimal point without any repeating pattern. this is a real number, not a rational number.

pi is per definition not rational (same thing as for sqrt(5) : infinite number of digits after the decimal point without any repeating pattern).

6x^4 + 14x^3 + 4x^2 -15x - 5

Step-by-step explanation:

(3x-1)(2x^3 + 4x^2 - 5)

we simply distribute and collect like terms

6x^4 + 14x^3 + 4x^2 -15x - 5

as you should already know, to get the inverse of any relation we start off by doing a quick switcheroo on the variables and then solve for "y".

[tex]\stackrel{f(x)}{y}=\cfrac{3}{4}x+9\implies \stackrel{quick~switcheroo}{x=\cfrac{3}{4}y+9}\implies x-9=\cfrac{3y}{4}\implies 4x-36=3y \\\\\\ \cfrac{4x-36}{3}=y\implies \cfrac{4}{3}x-12=\stackrel{f^{-1}(x)}{y}\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}[/tex]

Answer:

  x ≈ 3.9

Step-by-step explanation:

Call the segment shared by the two triangle "y". The Pythagorean theorem tells you ...

  sum of squares of sides = square of hypotenuse

  y² +6² = 10²

  x² +7² = y²

Substituting for y² using the second equation, we get ...

  x² +7² +6² = 10²

  x² = 10² -7² -6² = 100 -49 -36 = 15

Taking the square root, we find ...

  x = √15 ≈ 3.9
