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]

You roll 2 fair 6-sided dice. What is the probability of rolling a sum of 7 or more?
18/36 or 1/2
20/36 or 5/9
19/39
21/36 or 7/12
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).
Now, among these cases the cases where the sum is seven for (1,6), (2,5), (3,4), (4,3), (5,2), (6,1) i.e. there are 6 cases.
Now, it is time to calculate the probability.
The required probability is,
p = (No. of cases favorable for the event)/(Total no. of cases)
=6/36 =

A pipe leaks water at a rate of 48 fl oz
every 5 min.
At this rate, how many gallons of water leak from the pipe in an hour? (1
gal = 128 fl oz)
The number of gallons of water leaking from the pipe in an hour will be 4.5 gallons per hour.
What is conversion?Unit modification is the process of converting the measurement of a given amount between various units, often by multiplicative constants that alter the value of the calculated quantity without altering its impacts.
A pipe leaks water at a rate of 48 fl oz every 5 min. Then the rate is given as,
Rate = 48 / 5 fl oz per minute
We know that 1 gal = 128 fl oz, then we have
Rate = (48 / 128) / (5 / 60)
Rate = (48 x 60) / (128 x 5)
Rate = 2880 / 640
Rate = 4.5 gallons per hour
The number of gallons of water leaking from the pipe in an hour will be 4.5 gallons per hour.

The Johnson and Sloan families went to Taco Mania for lunch. The Johnsons bought 3 burrito meals and 4 taco meals for $48. The Sloans bought 6 burrito meals and 2 taco meals for $60. How much does each meal cost?
Answer:
Each burrito meal cost 8$
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

(Divide both sides by 3)

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?
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.

Assume that lines that appear to be tangent are tangent. O is the center of the circle. What is the value of x?
9514 1404 393
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

A polygon has perimeter 12 units. It is dilated with a scale factor of 3/4. What is the
perimeter of its image?
A. 9 units
B. 12 units
C. 16 units
With the given scale factor, perimeter of polygon's image is 9 units. Therefore, option A is the correct answer.
Given that, the perimeter of a polygon = 12 units and the scale factor = 3/4.
What is scale factor?A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).
The basic formula to find the scale factor of a figure is expressed as,
Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.
So, 3/4 = Dimensions of the new shape/12
= 3/4 × 12
= 3 × 3
= 9 units
With the given scale factor, perimeter of polygon's image is 9 units. Therefore, option A is the correct answer.
