Answer:

2.68 × [tex]10^{26}[/tex] Km³

Step-by-step explanation:

Using the given formula for volume V, then

V = [tex]\frac{4}{3}[/tex] π × (4 × [tex]10^{8}[/tex] )³

  = [tex]\frac{4}{3}[/tex] π × 4³ × ([tex]10^{8}[/tex] )³

 = [tex]\frac{4}{3}[/tex] π × 64 × [tex]10^{24}[/tex]

 = 268 × [tex]10^{24}[/tex]

 = 2.68 × 10² × [tex]10^{24}[/tex]

 = 2.68 × [tex]10^{26}[/tex] Km³

Answer:

Sara or x=15, Joe=27

Step-by-step explanation:

Using J to represent Joe and S to represent Sara

J=2S-3

J+S=42 or J=42-S

Substitute for J:

42-S=2S-3

3S=45

S=15

J=2(15)-3 = 27

Answer:

Answer:

[tex]m=\frac{2A-kn}{k}[/tex]

Hence, option C is true.

Step-by-step explanation:

Given the expression

[tex]A=\frac{k}{2}\left(m+n\right)[/tex]

Solving for 'm'

[tex]A=\frac{k}{2}\left(m+n\right)[/tex]

Flip the equation

[tex]\frac{k}{2}\left(m+n\right)=A[/tex]

Expanding by applying the distributive law: [tex]a\left(b+c\right)=ab+ac[/tex]

[tex]\frac{1}{2}km+\frac{1}{2}kn=A[/tex]

Add (-1)/2 × kn to both sides

[tex]\frac{1}{2}km+\frac{1}{2}kn+\left(-\frac{1}{2}kn\right)=\left(-\frac{1}{2}kn\right)+A[/tex]

simplify

[tex]\frac{1}{2}km=-\frac{1}{2}kn+A[/tex]

Divide both sides by k/2

[tex]\frac{\frac{1}{2}km}{\frac{k}{2}}=\frac{-\frac{1}{2}kn+A}{\frac{k}{2}}[/tex]

[tex]m=\frac{2A-kn}{k}[/tex]

Therefore,

[tex]m=\frac{2A-kn}{k}[/tex]

Hence, option C is true.

The ratios 3:8 and 4:7 are not proportion. You can tell this easily by how in the second ratio, the first number is one larger, but the second number is 1 lower. If this was proportional, then both numbers would go either up or down depending on the circumstance.

Answer:

6) q = -3

8) d = -4

10) y = 10

Step-by-step explanation:

6) -7q = 21

divide by -7 on both sides

q = -3

8) -1/3d = 12

divide both sides by -1/3

d = -4

10) -88 = -8y

divide both sides by -8

10 = y

or

y = 10

Answer:

5+a-4√a+1 / a-3

The rationalization of given expression is a+5-4√(a+1)/(a+5).

Rationalization can be considered as the process used to eliminate a radical or an imaginary number from the denominator of an algebraic fraction. That is, remove the radicals in a fraction so that the denominator only contains a rational number.

The given expression is √(a+1)-2/√(a+1)+2.

Multiply both numerator and denominator by (a+1)-2, we get

√(a+1)-2×(a+1)-2/√(a+1)+2×(a+1)-2

= (√(a+1)-2)²/(√(a+1))²+2²

= (√(a+1))²-2×√(a+1)×2+2²/a+1+4

= a+1-4√(a+1)+4/(a+5)

= a+5-4√(a+1)/(a+5)

Therefore, the rationalization of given expression is a+5-4√(a+1)/(a+5).

Answer:

5

Step-by-step explanation:

The constant of proportionality (r) in the equation y=rx is 3

The equation of the function is given as:

y = rx

Make r the subject

r = y/x

From the table, we have:

y = 36 when x = 12

So, the equation becomes

r = 36/12

Divide

r = 3

Hence, the constant of proportionality (r) in the equation y=rx is 3

Answer:

The smallest order of fractions in that order would be,

Step-by-step explanation:

1/6, 1/3, 1/2

because the bigger the denominater, the larger the whole is, and in 1/2, it would be equivalent to half, but 1/6 would be smaller. Let's say if it were 3/6, it would be equivalent to 1/2 because its half right? so thats another way you can tell how one fraction is smaller than another.

1/6,1/3,1/2 is the  list of fractions is in order from smallest to largest.

A fraction represents a part of a whole.

The given three fractions are 1/6, 1/3 and 1/2.

We need to order them smallest to largest.

Let us make the denominator same for all the three fractions to compare which is larger and smaller.

1/6×2/2=2/12

1/3×4/4=4/12

1/2×6/6=6/12

So 1/6 is smaller, 1/2 is bigger.

We know Arranging numbers in increasing order, that is, from smallest to largest is known as ascending order.

by using ascending order we can order the fractions like 1/6,1/3,1/2.

Hence, 1/6,1/3,1/2 is the  list of fractions is in order from smallest to largest.
