a. 1/3
b. 4/3
c. 3
d. the figure isn't dilated properly
Answers
measure ABCD=scale factor*[measure A1B1C1D1]
in the axis of the y coordinate
we have
scale factor=measure ABCD/measure A1B1C1D1
scale factor=3/1----->3
in the axis of the x coordinate
we have
scale factor=measure ABCD/measure A1B1C1D1
scale factor=8/6----->4/3
therefore
the answer is the option
d. the figure isn't dilated properly

Find the greatest common divisor of 100 and 254, using • prime factorization- • euclidean algorithm-
Answers
[tex]100=10^2=2^2\cdot5^2[/tex]
[tex]254=2\cdot127[/tex]
of which the only common factor is a single power of 2, so [tex]\mathrm{gcd}(100,254)=2[/tex].
Via the Euclidean algorithm:
[tex]254=2\cdot100+54[/tex]
[tex]100=1\cdot54+46[/tex]
[tex]54=1\cdot46+8[/tex]
[tex]46=5\cdot8+6[/tex]
[tex]8=1\cdot6+2[/tex]
[tex]6=3\cdot2+0[/tex]
which means [tex]\mathrm{gcd}(100,254)=2[/tex], as expected.
The Greatest Common Divisor (GCD) of 100 and 254 can be found using Prime Factorization and the Euclidean Algorithm. Both methods produce a GCD of 2.
Explanation:The student is asking for how to find the Greatest Common Divisor (GCD) of 100 and 254 using two different methods: Prime Factorization and the Euclidean Algorithm.
Prime Factorization: Start by writing down each number's prime factors. The prime factors for 100 are 2, 2, 5, 5 and the prime factors for 254 are 2, 127. The GCD is the product of the smallest power of each common prime number. In this case, the only common prime number is 2, so the GCD by prime factorization is 2.Euclidean Algorithm: This method begins with the larger number (254) and divides it by the smaller one (100). Write down the remainder (54). Then, divide the smaller number (100) by the remainder from the last step (54) to get a new remainder (46). The process is repeated until there is no remainder. The last non-zero remainder serves as the GCD. In this case, the process would continue as follows: 54 divided by 46 equals 1 remainder 8, then 46 divided by 8 equals 5 remainder 6, then 8 divided by 6 equals 1 remainder 2, then 6 divided by 2 equals 3, no remainder. Therefore, the GCD by Euclidean Algorithm is also 2.Learn more about Greatest Common Divisor here:https://brainly.com/question/23270841

Answers
(5+3)=8
Thus the value for k = 5/8
Answer:

Meryl needs to add enough water to 11 gallons of an 18% detergent solution to make a 12% detergent solution. Which equation can she use to find g, the number of gallons of water she should add?
Answers
the amount of detergent in 11 gal of 18% solution is the same as the amount of detergent in the 12% solution (after g gallons of water are added)
.18*11 = .12*(11+g)
Answer:
[tex]\frac{1.98}{11+g}=\frac{12}{100}[/tex]
Step-by-step explanation:
Given,
Total quantity of solution = 11 gallons
Initial detergent in the solution = 18 % of 11 gallons
[tex]=\frac{18\times 11}{100}[/tex]
[tex]=\frac{198}{100}[/tex]
[tex]=1.98\text{ gallons}[/tex]
Now, here g represents the number of gallons of water she should add to make 12 % detergent solution,
Final quantity of solution = ( 11 + g ) gallons
Thus, we can write,
The part of detergent in (11+g) gallons of water = The final percentage of detergent
[tex]\frac{1.98}{11+g}=\frac{12}{100}[/tex]
Which is the required equation.

The price of an item has risen to $276 today. Yesterday it was $115. Find the percentage increase.
Answers
276-115=131
131 divided by 276 = 0.47
0.47% increase
The student's question asked for finding the percentage increase in an item's price. This can be calculated by subtracting the initial price from the final price, dividing that difference by the initial price, and then multiplying the result by 100. In this case, the price of the item has increased by 140% from yesterday to today.
Explanation:To find the percentage increase of the price of an item, we subtract the initial price from the final price, then divide that number by the initial price, finally multiply that result by 100 to obtain the percentage. In this case, the initial price of the item was $115, and the final price is $276.
Here's how the calculation works:
Subtract the initial price from the final price: $276 - $115 = $161. Divide the difference by the initial price: $161 / $115 ≈ 1.4. Multiply the result by 100 to get the percentage increase: 1.4 * 100 = 140%.
Therefore, the price of the item has increased by 140% from yesterday to today.

A neighbor needs to put up a square fence around her garden to keep the deer out. If the area is 500 square feet, how much fence does she need to buy, rounded to the nearest tenth of a foot? Show your work.
Answers
And since it’s a square the length and width is the same amount
So width=length=L
500 ft^2=L*L=L^2
Square root both sides
Sqrt(500 ft^2) =L= 22.36067977
The neighbor needs to buy approximately 89.6 feet of fencing to surround her 500 square feet garden, which is a square. This is calculated by taking the square root of the area to find the length of one side and then multiplying by four to get the perimeter.
To determine how much fence the neighbor needs to buy to surround her square garden, we need to calculate the perimeter of the square. The area of a square is given by the formula Area = side × side or Area = side². Since the area is 500 square feet, we first find the length of one side of the square by taking the square root of the area:
Side = √Area = √500 ft²
The square root of 500 is approximately 22.4 feet. Now, we calculate the perimeter, which is the sum of all four sides of the square:
Perimeter = 4 × side = 4 × 22.4 ft = 89.6 ft
Rounded to the nearest tenth of a foot, the neighbor needs to buy approximately 89.6 feet of fencing to surround her garden.
how can x2+3x+1=2x2+2x+3 be set up as a system of equations
Answers
We then define the following unknowns:
incognitas: x and y.
We write the system of equations:
y = x2 + 3x + 1
y = 2x2 + 2x + 3
Answer:
y = x2 + 3x + 1
y = 2x2 + 2x + 3
The given equation can be converted into a system of equations by setting each side of the given equation to equal zero separately. The system of equations will then be x² - x + 2 = 0 and x² + 3x + 1 = 0.
Explanation:The given equation, x²+3x+1=2x²+2x+3, can be set as a system of equations by getting each side of the equation to equal zero. Begin by subtracting the entire left-hand side of the equation from the right-hand side which gives us:
2x² + 2x + 3 - (x² + 3x + 1) = 0
This simplifies to x² - x + 2 = 0. That's your first equation.
Now, take the left-hand side of the original equation and set it equal to zero: x² + 3x + 1 = 0. That's your second equation. So the system of equations from the original equation are:
x² - x + 2 = 0 x² + 3x + 1 = 0Learn more about System of Equations here:

A college cafeteria pays student cashiers $10.20 per hour. Cashiers earn an additional $1.30 per hour for each hour worked over 35 hours per week. A cashier worked 40 hours one week and 38 hours the second week. How much did this cashier earn in this two-week period?
Answers
Total Earning = 40 x $10.20 + (40 - 35) x $1.30 = $414.50
Second Week: 38 hours
Total Earning = 40 x $10.20 + (40 - 38) x $1.30 = $410.60
Total for the two weeks = $414.50 + $410.60 = $825.10
Answer: $825.10
Answer:
$806
Step-by-step explanation:
The regular earning of a cashier = $10.20 per hour
over 35 hours per week he gets = $10.20 + $1.30 per hour
= $11.50 per hour
He worked 40 hours in first week and 38 hours the second week.
His earnings in first week = (35 × 10.20) + (5 × 11.50)
= $357 + $57.5
= $414.50
His earnings in second week = (35 × 10.20) + (3 × 11.50)
= $357 + $34.50
= $391.50
His total earnings in this two weeks = $391.50 + $414.50
= $806
His total earning was $806.

Determine the number of x-intercepts that appear on a graph of each function. f (x) = (x + 2)(x - 1)[x - (4 + 3i )][x - (4 - 3i)]
Answers
f(x) has 2 x-intercepts.
Answer:
This function has two x-intercepts.
Step-by-step explanation:
The number of x-intercepts of a function is given by the number of REAL ROOTS of the function. A complex root does not intercept x.
In this function, we have
Two real roots: x = -2 and a x = 1
Two complex roots: x = -4 + 3i and x = -4 - 3i
So this function has two x-intercepts.

Assume that X has a normal distribution, and find the indicated probability. The mean is μ= 15.2 and the standard deviation is σ = 0.9. Find the probability that X is greater than 16.1.
Answers
Answer:0.1587
Step-by-step explanation:
z = (x-μ)/σ
mean, μ= 15.2
standard deviation, σ = 0.9
To find the probability that x is greater than 16.1,
x = 16.1
z = (16.1-15.2)/0.9
= 1
Looking at the normal distribution table, the area covered by 0 to 1
=0.8413
Therefore, the probability that x is greater than 16.1, = 11- probability that x = 16.1
= 1-0.8413
