Answer:
14 and 25
Step-by-step explanation:
x = smaller number
y = larger number
x + y = 39
x = y - 11
now we sub
y - 11 + y = 39
2y - 11 = 39
2y = 39 + 11
2y = 50
y = 50/2
y = 25 <=== larger number
x = y - 11
x = 25 - 11
x = 14 <==== smaller number
The problem can be solved by setting up and solving two algebraic equations. The two numbers in question are 25 and 14.
Explanation:The subject of this problem is algebra. To solve it, we can set up two equations based on the problem's statements, and then solve those equations.
First, we know that the sum of two numbers is 39, so we can write that as: x + y = 39 (Equation 1).
Second, we know that the smaller number is 11 less than the larger number. Assuming x is the larger number and y is the smaller one, we can write this as: y = x - 11 (Equation 2).
To solve these equations in parallel, insert Equation 2 into Equation 1, that results in: x + (x - 11) = 39. Solving this equation simplifies to 2x = 50, so x = 25. Substitute x = 25 in Equation 2, we get: y = 25 - 11 = 14. So, the two numbers are 25 and 14.

Answer:
2) m∠CBD = 60 3) x=15; 95 and 85 4) 12 = x; 98 for both angles
Step-by-step explanation:
2) 2x + 14 + x + 7 = 90 The angles add up to 90 degrees
3x + 21 = 90 Combine like terms
- 21 - 21 Subtract 21 from both sides
3x = 69 Divide both sides by 3
x = 23
Plug 23 in the equation
2(23) + 14
46 + 14
60
3) 2x + 65 + 3x + 40 = 180 The angles add up to 180 degrees
5x + 105 = 180 Combine like terms
- 105 - 105 Subtract 105 from both sides
5x = 75 Divide both sides by 5
x = 15
Plug in 15 into both equations
2(15) + 65 = 95
3(15) + 40 = 85
4) 5x + 38 = 9x - 10
- 5x - 5x Subtract 5x from both sides
38 = 4x - 10
+ 10 + 10 Add 10 to both sides
48 = 4x Divide both sides by 4
12 = x
Plug in 12 into both equations
5(12) + 38 = 98
9(12) - 10 = 98

Which of these statements are correct about a line segment with a length of 12 units in a coordinate plane? Select all that apply.
Correct statements are:
If it is reflected across the y-axis, its length still will be 12 units.
If it is rotated 270° about the origin, its length still will be 12 units.
If it is translated 15 units up, its length still will be 12 units.
Step-by-step explanation:
Whatever it may be rotation, reflection or translation, the size of the line will never change. So length of the line is same as 12 units in the image.
So the wrong statements are
If its reflected across y = -x then the length will no longer be 12 units.
If it is rotated 90° about the origin, then the length will no longer be 12 units.
If it is translated 18 units to the right, then the length will no longer be 12 units.
You can use the fact that reflection, rotation or translation, all three are not modifying the line itself and only its position can change. Whatever be the position, if the line segment itself isn't modified, the length will be same.
Thus, the correct choices are:
Option A: If it is reflected across the y-axis, the length will still be 12 units.Option B: If it is rotated 270° about the origin, its length still will be 12 units.Option E: If it is translated 15 units up, its length still will be 12 units.Rest of the choices are wrong since they blame reflection or rotation or translation to modify the length of that line segment.
Why is the length of a line segment not modified when it is reflected along an axis, rotated or translated by some units in some direction?Suppose you've got a baseball stick. Will it's length change when you take it somewhere else like from your home to playground? No. Will its length change if you hold it upside down? No.
This is the same case with line segment being rotated, reflected, or translated. All these processes do not change the line segment's length and can just move that line segment from one position to other.
Using above conclusion to find the correct options in the given contextSince reflection, rotation, or translation won't affect the length of the line segment,.
Thus, the correct choices are:
Option A: If it is reflected across the y-axis, the length will still be 12 units.Option B: If it is rotated 270° about the origin, its length still will be 12 units.Option E: If it is translated 15 units up, its length still will be 12 units.Rest of the choices are wrong since they blame reflection or rotation or translation to modify the length of that line segment.

11,304 mm2
C.
753.6 mm2
D.
45,216 mm2
Option B: [tex]11,304 \mathrm{mm} ^2[/tex] is the area of the compact disc.
Explanation:
The diameter of the compact disc is [tex]120mm[/tex].
To determine the area of the compact disc, let us substitute the values in the area of the circle formula,
[tex]A=\pi r^2[/tex] where [tex]r=\frac{d}{2}[/tex]
Substituting the value of d in [tex]r=\frac{d}{2}[/tex], we get,
[tex]r=\frac{120}{2} =60[/tex]
Thus, [tex]r=60[/tex] and [tex]\pi=3.14[/tex]. Let us substitute these values in [tex]A=\pi r^2[/tex], we get,
[tex]A=3.14\times(60)^2[/tex]
Simplifying, we have,
[tex]A=3.14\times3600[/tex]
Multiplying, we get,
[tex]A=11304mm^2[/tex]
Thus, the area of the compact disc is [tex]11,304 \mathrm{mm} ^2[/tex]
Hence, Option B is the correct answer.

Carle is cutting pieces of string that are exactly 24 3/8 inches long. How many pieces can she cut from a ball of string that has 100 feet
49 pieces of string can be cut from a ball of string that has 100 feet
Solution:
Given that, Carle is cutting pieces of string that are exactly 24 3/8 inches long
Therefore,
[tex]Length\ of\ each\ string = 24\frac{3}{8}\ inches = \frac{8 \times 24 + 3}{8} = \frac{195}{8}\ inches[/tex]
How many pieces can she cut from a ball of string that has 100 feet
Total length of string = 100 feet
Convert feet to inches
1 feet = 12 inch
100 feet = 1200 inch
Therefore, number of pieces that can be cut is given as:
[tex]\text{Number of pieces } = \frac{\text{total length of string}}{\text{length of each string}}[/tex]
Substituting the values we get,
[tex]\text{Number of pieces } = \frac{1200}{\frac{195}{8}}\\\\\text{Number of pieces } = 1200 \times \frac{8}{195}\\\\\text{Number of pieces } = 49.2307 \approx 49[/tex]

I need help with pythagoras’ theorem
Answer:
Pythagoras’ theorem is a way to find a side or hypothesis when you have 2 sides.
The formula is: a^2 + b^2 = c^2
a and b are sides
c is the hypothesis
Ex: A triangle has a leg that is 5 inches and a leg that is 7 inches. Find the hypothesis using Pythagoras' theorem.
A leg is another way of saying a side.
5^2 + 7^2 = c^2
25 + 49 = x^2
sqrt(74) = sqrt(x^2)
sqrt(74) inches = hypothesis
Ex: A triangle has a leg that is 9 feet and a hypothesis that is 25 feet. Find the other leg using Pythagoras' theorem.
9^2 + b^2 = 25^2
81 + b^2 - 81 = 625 - 81
sqrt(b^2) = sqrt(544)

A principal of 3700 is invested at 4.75 %interest, compounded annually. How much will the investment be worth after 5 years?
The investment will be worth $4686.62 after 5 years.
Step-by-step explanation:
Principal, P = 3700
Rate, r = 4.75% = 0.0475
Number of years, t = 5 years
Number of times compounded, n = 5 times
Amount = P(1 + r/n)^nt
⇒ 3700 (1 + 0.0475/5)^25
⇒ 3700 (5.0475/5)^25
⇒ 3700 (1.0095)^25
⇒ 4686.62

How many gallons of a 50% antifreeze solution must be mixed with 70 gallons of 30% antifreeze to get a mixture that is 40% antifreeze?
Answer:
70 gallons
Step-by-step explanation:
x gallon of 50%
x * 0.5 + 70 * 0.3 = (x + 70) * 0.4
0.5x + 21 = 0.4x + 28
0.1x = 7
x = 70
To get a mixture that is 40% antifreeze, we need to mix 70 gallons of 30% antifreeze solution with 40 gallons of 50% antifreeze solution. This conclusion is reached by establishing an equation representing the total amount of antifreeze in the mixture before and after and then solving for the unknown.
Explanation:Your question deals with the concept of a weight ratio in a chemical mixture. Specifically, we're going to solve it using algebra. Let's say you need x gallons of the 50% antifreeze solution. We can work this out by forming an equation based on the information given in the problem:
The total amount of antifreeze in the 70 gallons of 30% solution and x gallons of 50% solution must be equal to the total amount of antifreeze in the (70 + x) gallons of 40% solution.
Therefore, we can write: 0.3 * 70 + 0.5 * x = 0.4 * (70 + x)
Solving the equation above, we find that x equals 40 gallons. So, you would need to mix 40 gallons of a 50% antifreeze solution with 70 gallons of 30% solution to obtain a final solution with a 40% antifreeze concentration.
