find X,Y & all 4 angles
Answer:
x=900/47, y=720/47
4x=5y == 3600/47 (top and bottom angle values)
3x+3y == 4860/47 (left and right angle values)
If you want the values in mixed number form, reply back.
Step-by-step explanation:
You can set this up in many different ways.
First, the inverse angles are always equal, so 4x=5y
Additionally, 2 sets of angles are supplementary, meaning they add up to 180 degrees; they are 4x+3x+3y=180 and 5y+3x+3y=180; both are equal
You could simplify the above two equations to get 7x+3y=180 and 3x+8y=180, meaning that 7x+3y=3x+8y, and 4x=5y
This simplifies to y=4x/5
Additionally, you could add the equations, meaning that 10x+11y=360, and y=4x/5
This gives you the answer:
x=900/47 and y=720/47.
You could check this by plugging the values into the equation, and if you do the math (which, I know, is kind of painful), you get the supposed values, so hooray!
Answer:
The angles measuring 4x and 5y measure: 3600/47
The other two angles measure: 4860/47
Step-by-step explanation:
The angles measuring 4x and 5y are vertical angles. Vertical angles are congruent, so we have one equation: 4x = 5y.
The angles measuring 5y and 3x + 3y form a linear pair. Angles in a linear pair are supplementary, so their measures add up to 180 degrees. That gives us a second equation: 3x + 3y + 5y = 180, or simply 3x + 8y = 180.
We have a system of two equations in two unknowns, so we can solve for x and y.
4x = 5y
3x + 8y = 180
We will use the substitution method.
Solve the first equation for x: x = 5y/4
Substitute 5y/4 for x in the second equation.
3(5y/4) + 8y = 180
15y/4 + 8y = 180
15y + 32y = 720
47y = 720
y = 720/47
Substitute y with 720/47 in the first original equation and solve for x.
4x = 5y
4x = 5(720/47)
4x = 3600/47
x = 900/47
The angles measuring 4x and 5y measure: 4x = 4(900/47) = 3600/47
The other two angles measure: 3x + 3y = 3(900/47) + 3(720/47) = 2700/47 + 2160/47 =4860/47
In 2000 South Dakota had a population of 754,844. The number of people in South Dakota increased by 7.9% in 2010. What is South Dakota's approximate population in 2010?
814,180. Hope I helped. If i didn't I am sos sorry. I would take 7.9 or .079 to 754,844 to get your number.
The approximate population of South Dakota in 2010 after a 7.9% increase from the 2000 population is 814,477 people.
To find the population of South Dakota in 2010, we need to calculate the increased population based on the given percentage increase. We are provided with a population of 754,844 in 2000 and an increase of 7.9% for 2010.
Here is the step-by-step calculation:
Multiply the population of 2000 by the increase percentage (converted to a decimal):
754,844 x 0.079 = 59,632.68.
Add this increase to the 2000 population to get the 2010 population:
754,844 + 59,632.68 = 814,476.68.
Therefore, the approximate population of South Dakota in 2010 is 814,477 people (rounded to the nearest whole number).
HELP!!!! An electrician cuts a 26 ft piece of wire into two pieces. One piece is two feet longer than the other. How long are the pieces?
Let 1 piece = X
The 2nd piece would be X + 2 feet
Add:
x +x+2 = 26 feet
2x +2 = 26 feet
Subtract 2 from each side:
2x = 24
Divide both sides by 2:
x = 24 / 2
X = 12
One piece is 12 feet the other piece is 14 feet.

How do you turn a percent into a fraction
Step 1: You want to remove the percent sign and then put the number over 100.
Step 2: If the percent is not a whole number then you want to multiply the top and bottom number by 10 but only for every number that comes after the decimal point.
Step 3: Always simplify if possible.
Examples:
43% = [tex]\frac{43}{100}[/tex]
78% = [tex]\frac{78}{100}[/tex] = [tex]\frac{39}{50}[/tex]
0.4% = [tex]\frac{0.4}{100}[/tex] = [tex]\frac{4}{1000}[/tex] = [tex]\frac{1}{250}[/tex]

I believe the answer is 100 milliliters
The capacity of the beaker is is 100 ml
Further Explanation
The capacity of a beaker is 0.1 L, convert this to milliliters (ml). We can say that the capacity in ml is variable x.
We know that:
[tex]\boxed {1L = 1000ml }\\[/tex]

Because you can't solve for X and Y at the same time and 40 = 12x + 4 y.
To find the values of x and y in the equation 40 = 12x + 4y, isolate the x term and solve for x, then substitute the value of x into the equation to solve for y.

Alicia bought 4 T-shirts for $23.00. Using the unit rate, how much would 6 T-shirts cost?
i think that you would just take 23/4=$5.75
so take 6 times 5.75 and you should get $34.5
To answer this question, we first need to determine the unit cost (cost per t-shirt).
Step 1: Find the unit cost
Alicia bought 4 T-shirts for a total of $23.00. To calculate the cost per T-shirt (the unit rate), we need to divide the total cost by the number of T-shirts.
So, $23.00 (total cost) divided by 4 (number of T-shirts) equals $5.75. Thus, the unit cost of one T-shirt is $5.75.
Step 2: Calculate the cost for 6 T-shirts
Now that we know the unit cost, we can find out how much 6 T-shirts will cost. To do this, we multiply the unit cost by the number of T-shirts.
So, $5.75 (cost per T-shirt) times 6 (number of T-shirts) equals $34.50.
Therefore, it would cost $34.50 for 6 T-shirts, given the unit rate.
What is −9/4v+4/5=7/8 thanks!
To solve the equation -9/4v + 4/5 = 7/8, subtract 4/5 from both sides, find a common denominator for 7/8 and 4/5, simplify, and multiply by 4/9 to solve for v.
Explanation:To solve the equation -9/4v + 4/5 = 7/8, we need to isolate the variable v. To do this, we can start by subtracting 4/5 from both sides of the equation, which gives us -9/4v = 7/8 - 4/5. Next, we need to find a common denominator for 7/8 and 4/5. The least common multiple of 8 and 5 is 40, so we can rewrite both fractions with a denominator of 40. This gives us -9/4v = 35/40 - 32/40. Continuing to simplify, we get -9/4v = 3/40. To get rid of the fraction, we can multiply both sides of the equation by 4/9, canceling out the fraction on the left side. This gives us v = (3/40) * (4/9), which simplifies to v = 1/30.

A. 1,926 pounds/hour
B. 2,408 pounds/hour
C. 10.13 pounds/minute
D. 26.75 pounds/minute
Answer:
D. 26.75 pounds/minute
Step-by-step explanation:
For calculate unit rate that reflects the speed of the processor we can use the following equation:
[tex]Speed = \frac{Total Pounds}{RequiredTime}[/tex]
Taking into account that the answers are in pounds per hour and pounds per minute, we re going to calculate the speeds in booth units.
1. Speed in Pounds per hours: Replacing Total Pounds by 4,815 and Required time by 3 hours, we get:
[tex]Speed = \frac{4,815Pounds}{3 Hours}=1,605 Pounds/hour[/tex]
2. Speed in Pounds per minute: Every hour have 60 minutes, the 3 hours have 180 minutes, so replacing Total Pounds by 4,815 and Required time by 180 minutes, we get:
[tex]Speed = \frac{4,815Pounds}{180 Hours}=26.75 Pounds/hour[/tex]
So, chosen the rate that appear in the answers, we can say that the correct answer is D. 26.75 pounds/hours.
A gardener transplanted a plant from an indoor pot to an outdoor garden. After 30 days, the plant's height was 18 centimeters. After 90 days, it was 29 centimeters. Write an equation to represent the plants growth where the x is the days and the y is the height of the plant.
Let x is the days and the y is the height of the plant.
Let the change between x and y is linear.
So, the relation between x and y will take the form ⇒ y = ax + b
where a and b are constants.
At x = 30 ⇒ y = 18 ⇒⇒⇒ ∴ 18 = 30 a + b → (1)
At x = 90 ⇒ y = 29 ⇒⇒⇒ ∴ 29 = 90 a + b → (2)
solve (1) and (2) to find a and b
subtract (1) from (2)
∴ 11 = 60 a ⇒⇒⇒ ∴ a = 11/60
substitute at (1) ⇒⇒⇒ ∴ b = 25/2 = 12.5
So, the equation which represents the plants growth is
∴ y = (11/60) x + 12.5

What is m∠A?
47°
67°
25°
92
The measure of angle ∣4 is 250 degrees. The measure of angle ∣A is 67 degrees.
Explanation:To find the measure of angle ∣4, we can use the fact that angles around a point add up to 360 degrees.
We know that ∣1 is 45 degrees and ∣3 is 65 degrees.
To find ∣4, we can subtract the sum of angles ∣1 and ∣3 from 360 degrees.
Therefore, ∣4 = 360 - (∣1 + ∣3) = 360 - (45 + 65) = 360 - 110 = 250 degrees.
To find the measure of angle ∣A, we can use the fact that the sum of the angles in a triangle is 180 degrees.
We know that ∣B is 90 degrees because it is a right angle.
Therefore, ∣A + ∣B + ∣C = 180 degrees.
Substituting the given values, we get (3x - 8) + 90 + (x - 2) = 180. Simplifying the equation, we get 4x + 80 = 180.
Solving for x, we get x = 25.
Substituting x back into the equation for ∣A, we get ∣A = (3(25) - 8) = 67 degrees.
