Answer:

500 bricks.

Step-by-step explanation:

There are 250 bricks used to build a wall that is 20 feet high how many bricks will be used to build a wall is 40 feet high?

To solve e the above question, we have:

20 feet high = 250 bricks

40 feet high = x bricks

Cross Multiply

20 feet × x bricks = 40 feet × 250 bricks

x bricks = 40 feet × 250 bricks/20 feet

x bricks = 500 bricks

Therefore, 500 bricks will be used to build a wall is 40 feet high.

Answer:

  x = 20, or 125

Step-by-step explanation:

We cannot tell the angle x is intended to refer to. So, here are two answers. Choose the one you think applies.

__

The triangle that includes both marked angles is a right triangle. (The tangent meets the circle at right angles to the radius.) So, the angle x° at the external point is the complement of the marked central angle.

  x° = 90° -70°

  x = 20

__

If x° is referring to the exterior angle associated with the isosceles triangle within the circle, then its measure is the supplement of the interior base angle of that triangle. It is ...

  x° = 180° -(180° -70°)/2 = 90° +70°/2

  x = 125

Answer:

Apple Pie cost $8

Lemon Meringue Pie = $15

Step-by-step explanation:

Creating some variables:

A = apple pie

L = lemon meringue pie

We have two equations:

11A + 1L = 103

11A + 12L=268

You can use elimination or the substitution method to solve. I will be using substitution method.

Solve the first equation for L:

11A + 1L = 103

subtract 11A to both sides

L = 103 - 11A

Plug this into the second equation

[tex]11A + 12(103-11A) =268[/tex]

distribute the 12

[tex]11A + 1236 - 132A = 268[/tex]

combine the A and subtract the 1236

[tex]-121A = -968[/tex]

Divide -968 by -121

A = 8

Next plug this 8 back into one of the two original equations above:

[tex]11(8) + 1L =103[/tex]

[tex]88+L=103[/tex]

subtract 103 by 88

L = 15

Answer:

[tex]A=8[/tex], [tex]L=15[/tex]

Step-by-step explanation:

For the sake of time Apple pies will be represented by [tex]A[/tex] and Lemon will be represented by [tex]L[/tex]

Based on the information given it is clear that:

[tex]11A+1L=103[/tex]

[tex]11A+12L= 268[/tex]

We can rearrange the first equation to solve for [tex]A[/tex], in terms of [tex]L[/tex]

[tex]11A+1L=103[/tex]

subtract [tex]1L[/tex] form both sides

[tex]11A=103-L[/tex]

Now let's input this into the second equation to solve for [tex]L[/tex]

[tex](103-L)+12L=268[/tex]

combine like terms

[tex]11L+103=268[/tex]

subtract [tex]103[/tex] from both sides

[tex]11L=165[/tex]

divide both sides by [tex]11[/tex]

[tex]L=15[/tex]

Now input  this value into the first equation for [tex]L[/tex]

[tex]11A+15=103[/tex]

subtract [tex]15[/tex] from both sides

[tex]11A=88[/tex]

divide both sides by [tex]11[/tex]

[tex]A=8[/tex]

Step-by-step explanation:

This is well within the mass uncertainty of 0.01% (6×1020 kg), so the estimated value of Earth's mass is unaffected by this factor. Mass loss is due to atmospheric escape of gases. About 95,000 tons of hydrogen per year (3 kg/s) and 1,600 tons of helium per year are lost through atmospheric escape.

Answer:

x = 40

Step-by-step explanation:

x + 100 +  x = 180 {Straight line angles}

2x   + 100 = 180      {subtract 100 from both sides}

         2x = 180 - 100

         2x = 80      {Divide both sides by 2)

           x = 80/2

          x = 40

Answer:

x=40

Step-by-step explanation:

2x+100=180

2x=180-100

2x=80

x=40

Answer:

24 = x

Step-by-step explanation:

You use Pythagorean theorem. Since the normal equation is [tex]a^{2} + b^{2} =c^{2}[/tex], you already have the [tex]c^{2}[/tex] and another side which can be [tex]a^{2}[/tex] or [tex]b^{2}[/tex].

Because you have the hypotenuse and a side , your equation looks like this now: [tex]7^{2} +b^{2} = 25^{2}[/tex]

and when you solve for be you just subtract [tex]25^{2} -7^{2}[/tex] to get 24.

Step-by-step explanation:

All you have to do is divide 42/2

Becuase 14 is 7 doubled

Answer:

The second option is correct.

Step-by-step explanation:

First you need to find a common denominator in which is 6

You can find it like this:

1 x  3 = 3

2 x  3 = 6

3/6 is the amount of cake that was left

Now do the same thing for the amount of cake that Elisa ate.

1 x  2 = 3

3 x 2 = 6

So in conclusion the second option represents the amount of cake Elisa eats the best.

I hope this is as helpful as possible.

Answer:

Model:

2/3 (original amount of cake) - 1/3 (what was left) = 1/3 (what Elisa ate)

Math:

2/3 - 1/3 = 1/3

Calculation:

2/3 - 1/3 = (2 - 1) / 3

= 1 / 3

Explanation:

To calculate the fraction of the cake Elisa ate, we need to subtract 1/3 from 2/3. First, we need to find a common denominator for both fractions. In this case, the common denominator is 3. Then, we need to subtract the numerator of the second fraction, which is 1, from the numerator of the first fraction, which is 2. The difference is 1, which is the numerator of the fraction that represents the amount of cake Elisa ate. The denominator is 3, so the fraction that represents the amount of cake Elisa ate is 1/3.

The number of possible 3 - digit codes would be 900.

"A combination is a way of selecting items from a collection."

For given situation,

It is a three digit code with 0 can't be the first digit.

This means the for this combination first digit can takes values from 1 - 9 and the second and third digits can take values from 0 - 9.

So, the number of possible 3 - digit codes would be,

9 × 10 × 10 = 900

Therefore, the number of possible 3 - digit codes would be 900.

Answer:

   here we have rolled two dice. So total no. of possible outcomes will be 6^2=36. These are (1,1),(1,2),(1,3),(1,4),(1,5),(1,6),(2,1),(2,2),(2,3),(2,4),(2,5),(2,6),(3,1),(3,2),(3,3),(3,4),(3,5),(3,6),(4,1),(4,2),(4,3),(4,4),(4,5),(4,6),(5,1),(5,2),(5,3),(5,4),(5,5),(5,6),(6,1),(6,2),(6,3),(6,4),(6,5),(6,6).

Answer:

Each burrito meal cost 8$

Each taco meal cost 6$

Step-by-step explanation:

Johnsons= 3b +4t =48

Sloans= 6b+2t=60

multiple johnsons by -2

so, now the johnsons are -6b+-8t=-96

add that to the sloans so, -6b+6b-8t+2t=-96+60

the b's cancel eachother out, so you are left with -6t= -36

divide each side by -6 and you will get t=6

then you can pick either formula, lets say sloans this time

so, 6b + 2(6)=60 so, 6b+12=60, subtract 12 from each side, to get 48

so 6b=48, divde each side by 6 and you will get b=8

Step-by-step explanation:

Answer:

Tacos-6

Burritos-8

Step-by-step explanation:

Multiply the first equation by -2,and multiply the second equation by 1.

−2(3b+4t=48)

1(6b+2t=60)

Becomes:

−6b−8t=−96

6b+2t=60

Add these equations to eliminate b:

−6t=−36

Then solve−6t=−36for t:

−6t=−36

−6t

−6

=

−36

−6

(Divide both sides by -6)

t=6

Now that we've found t let's plug it back in to solve for b.

Write down an original equation:

3b+4t=48

Substitute6fortin3b+4t=48:

3b+(4)(6)=48

3b+24=48(Simplify both sides of the equation)

3b+24+−24=48+−24(Add -24 to both sides)

3b=24

3b

3

(Divide both sides by 3)
