One grain of sand weighs 0.00007g.
How many grains of sand are there in 6300kg if sand?

Answer: Y = 12 Kids tickets

X =  # Of Adults = 8

Y = # Of Children = 12

(X+Y = 20) - 15

20x+15y = 340

-15x - 15y = -300

20x + 15y = 340

----------------------

5x = 40

--       --

5       5

X = 8

(8) + Y = 20

Y=12

Answer:

see explanation

Step-by-step explanation:

1

[tex]\frac{2}{3}[/tex] x - 4 = 20 ( multiply through by 3 to clear the fraction )

2x - 12 = 60 ( add 12 to both sides )

2x = 72 ( divide both sides by 2 )

x = 36

2

4 = [tex]\frac{-1+x}{2}[/tex] ( multiply both sides by 2 to clear the fraction )

8 = - 1 + x ( add 1 to both sides )

9 = x

3

12(x + 9) = - 108 ( divide both sides by 12 )

x + 9 = - 9 ( subtract 9 from both sides )

x = - 18

4

5x + 14 = - 7 ( subtract 14 from both sides )

5x = - 21 ( divide both sides by 5 )

x = - [tex]\frac{21}{5}[/tex] = - 4.2

Answer:

101

Step-by-step explanation:

The leftover weight that can be put onto the container (x)

x = 24500 - 12300

x = 12200

The amount of crates that can be hauled into the container

x = 12200 / 120

= 101.6667

We need a whole number so we round down.

= 101

Step-by-step explanation:

hypotunes isnt involved(as the length inst given and we know it is hypotunes as it is the oppisite direction from the right angle)

so sohcahtoa

therefore ir toa

tan(x)=o/a

(tan inverse)tan^-1=34/54

oppisite= 34 as it is oppisite to teh angle your trying to find

and the adjacent is beetwen the right angle and the angle your mesuring

The angle x is 32.2° which is opposite to the side perpendicular of the length 34.

Right angled triangle:

A right angle triangle have one angle as right angle, the side opposite to the right angle is called hypotenuse and the side on which angle 90 degree is created is called base. The third side is called perpendicular.

Here we have given that

Perpendicular = CD = 34

Base = BC = 54

If we apply tan on this triangle we will find the relation between angle B, CD and BC.

we know that

tan x = [tex]\frac{perpendicular}{base}[/tex]

Using tan into our given triangle we have

[tex]tanx=\frac{CD}{BC}[/tex]

[tex]tanx=\frac{34}{54}[/tex]

[tex]tanx=0.629629[/tex]

[tex]x=tan^-1(0.629629)\\\\x=32.2[/tex]

Hence the final answer is 32.2°

Using proportions, it is found that the Customer Acquisition Cost was of $1,215.

A proportion is a fraction of a total amount.

In this problem, the customer acquisition cost is the spending in sales divided by the number of customers added.

80 customers were added, considering costs of 1200 + 9000 + 87000 = $97,200, hence:

97200/80 = $1,215.

Answer:

x = 7 , y = 12

Step-by-step explanation:

using the rule of exponents

[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex]

consider left side

[tex]6^{\frac{1}{3} }[/tex] × [tex]6^{\frac{1}{4} }[/tex]

= [tex]6^{(\frac{1}{3}+\frac{1}{4}) }[/tex]

= [tex]6^{(\frac{4}{12}+\frac{3}{12}) }[/tex]

= [tex]6^{\frac{7}{12} }[/tex] = [tex]6^{\frac{x}{y} }[/tex] , comparing exponents , then

x = 7 and y = 12

Answer:

  y = 5·4^x

Step-by-step explanation:

If you have two points, (x1, y1) and (x2, y2), whose relationship can be described by the exponential function ...

  y = a·b^x

you can find the values of 'a' and 'b' as follows.

Substitute the given points:

  y1 = a·b^(x1)

  y2 = a·b^(x1)

Divide the second equation by the first:

  y2/y1 = ((ab^(x2))/(ab^(x1)) = b^(x2 -x1)

Take the inverse power (root):

  (y2/y1)^(1/(x2 -x1) = b

Use this value of 'b' to find 'a'. Here, we have solved the first equation for 'a'.

  a = y1/(b^(x1))

In summary:

__

For the problem at hand, (x1, y1) = (2, 80) and (x2, y2) = (5, 5120).

  b = (5120/80)^(1/(5-2)) = ∛64 = 4

  a = 80·4^(-2) = 80/16 = 5

The exponential function is ...

  y = 5·4^x

Answer:

25

Step-by-step explanation:

25, because 3 times what is 15, 5. So multiply 5 by 5 and get 25.

Answer:

25

The set-up would go something like this:

3 * x = 15

x is our variable that isn't defined, bur by doing some simple math we can determine that "x" is 5 becuase of simple logic and reasoning.

This means that you would also have to multiple the 5 by the 5 as well since we know that for every 3 white cars there is 6l5 blue cars.

this would bring the total to 25z hope this helped :)
