Find the measure of ∠d. PLEASE HELP
Answer:
107
Step-by-step explanation:
3x + 16 + 5x - 4 = 180 (Being linear pair)
8x + 12 = 180
8x = 180 - 12
8x = 168
x = 21
3x + 16 = 3 * 21 + 16 = 79
< C = 79 ( being corresponding angles)
< d + < c = 180 ( being linear pair)
< d = 180 - 79
< d = 107

How would I be able to get the step by step prosses of this and the answer of y?
(-7) = (-4y) + 5
Answer:
y = 3
Step-by-step explanation:
-7 = -4y + 5
Subtract 5 from both sides to isolate variable y:
-7 - 5 = -4y + 5 - 5
-12 = -4y + 0
-12 = -4y
Divide both sides by -4 to isolate variable y:
-12 ÷ -4 = -4y ÷ -4
(Negative ÷ Negative = Positive)
3 = 1y
3 = y
Check your work:
-7 = -4(3) + 5
Use PEMDAS:
-7 = -12 + 5
-7 = -7

0.94 cups of milk is required for 5 batches of the macaroni and cheese.
Given that the recipe for macaroni and cheese takes:
3 tablespoons of milk
and 2 tablespoons of butter
To find: the number of cups of milk required
Let m be the number of cups of milk is required to make 5 batches of the macaroni and cheese.
a batch of the macaroni and cheese require 3 tablespoons of milk .
So by unitary method for 5 batches of the macaroni and cheese,
(5 × 3) = 15 tablespoons of milk is required.
We know that 1 US Cup = 16 US tablespoons
So by unitary method,
m = 15/16 cups of milk

B. a reflection across the line y = - 2x + 3
C. a rotation 90° clockwise around the origin
D. a dilation centered at the origin with a scale factor of
Answer: Choice D
Step-by-step explanation: A dilation would result in a similar triangle because multiplying by the scale factor will create proportional sides. However, this will change the size of the triangle, making it not congruent.
Answer:
D.
Step-by-step explanation:
Congruent means that the triangles are exactly the same in shape and size.
Dilating the triangle is the only answer that will change its size.

Some epidemiologists are planning a second study to evaluate the PSA screening test. The only difference is that this time, the men from Reno who they randomly sample will be 44-59 years of age. Age is a strong risk factor for prostate cancer. The prevalence of prostate cancer in men 44-59 years of age will be much lower than the prevalence of prostate cancer in men 60-75 years of age. How do you expect the results of the second study will compare with the results from the study conducted among 60-75 year old men
Answer:
The second test result will be lower and more sensitive to changes than the first test result and it will better test the efficacy of the PSA screening test
Step-by-step explanation:
The evaluation the epidemiologist are planning = Prostrate Specific Antigen, PSA, screening test
The given difference between the first and second study = The age range of the study group
The age range of the first study = 60 to 75 years
The age range of the second study = 44 to 59
The prevalence of prostrate cancer in men 44 to 59 years of age < The prevalence of prostrate cancer in men 60 to 75 years of age
Therefore, due to the low prevalence, the result of the second test will be more sensitive than the result of the first test.

It takes 126 cubes that have edge lengths of 1/3 ft to completely fill a plastic bin. What is the area of the base of the bin?
The area of the base of the bin is 9 ft^2.
The given information states that the bin is filled with 126 cubes that have edge lengths of 1/3 ft. To determine the area of the base of the bin, we must first determine the total volume of the bin.
Since each cube has a volume of 1/27 ft^3, the total volume of the bin is 126/27 ft^3. Since the volume of a rectangular prism is equal to the length times the width times the height, we can solve for the area of the base of the bin by rearranging the formula to A = V/h, where A is the area, V is the volume, and h is the height.
We can substitute the values given to obtain A = 126/27 ft^3/h. Since the height of the bin is equal to the edge length of the cubes, which is 1/3 ft, we can substitute that value into the equation to get A = 126/27 ft^3/1/3 ft = 9 ft^2. Therefore, the area of the base of the bin is 9 ft^2.

What is the domain of exponential function f/x )= BX?
The domain of an exponential function is all real numbers. In the interval notation is (-∞, ∞).
What is interval notation?
A set of real numbers known as an interval in mathematics contains all real numbers falling inside any two of the set's numbers. For instance, the interval containing 0, 1, and all integers in between is the set of values x satisfying 0 ≤ x ≤ 1 .
Given exponential function is f(x) = B^x.
A function with an exponent as the independent variable is called an exponential function. The general form of an exponential function is y = f (x) = B^x, where B > 0 and a > 1, and x is any real number. The function is undefined for -1 < x < 1 if an is negative, which is why a > 0 is true. The function can have a domain that includes all real numbers by limiting a to positive values.

A certain United States flag has a perimeter of 58 feet. The length of the flag is 9 feet longer
than the width. What are the dimensions of the flag?
The dimensions of the flag are:
length = 19 feet and width = 10 feet
Let 'l' be the length of the flag and 'w' be the width of the flag.
The length of the flag is 9 feet longer than the width.
So, we get an equation
l = 9 + w ............(1)
The flag has a perimeter of 58 feet.
We know that the formula for the perimeter of rectangle:
P = 2(l + w) ..............(2)
Here, P = 58 feet
Substitute the value of P in equation (2)
58 = 2(l + w)
29 = (9 + w) + w ..........(from (1))
29 - 9 = 2w
2w = 20
w = 10
Substitute this value in equation (1),
l = 9 + 10
l = 19 feet
Therefore, length = 19 ft and width = 10 ft

A different computer is advertised as 30% off of the original price. After the discount, the tax is $78.75
• Determine the original price of this computer.
Show your work or explain your answer.
The percentage is calculated by dividing the required value by the total value and multiplying it by 100.
How to calculate original price of computer?The original price of the computer is 112.5 .The amount saved is 33.75The percentage is calculated by dividing the required value by the total value and multiplying it by 100.
Here,
Required percentage value = a
total value = b
Percentage = a/b x 100
We have,
Coupon = 30% off
Coupon = 30% off= 78.75
This means that the cost of the computer is only 70% since 30% is off.
70% = 78.75
We know that the original price is 100%.
So,
70% = 78.75
Multiply 100/70 on both sides.
100/70 x 70% = 100/70 x78.75
100% =112.5
The original price of the computer is 112.5
The amount saved is:
112.5-78.75=33.75
Thus,
The original price of the computer is 112.5
The amount saved is 33.75

Solve the given differential equation. 3x^2y'' + 6xy' + y = 0
The solution for given differential equation is y = c1e^(-x^3/3) + c2xe^(-x^3/3)
This is a second-order linear differential equation with constant coefficients. To solve this equation, we can use the method of an auxiliary equation, which is 3r^2 + 6r + 1 = 0. This equation has two complex conjugate roots, r = -3 ± i√3. Therefore, the solution of the differential equation is y = c1e^(-x^3/3) + c2xe^(-x^3/3)cos(√3x^2/2) + c3xe^(-x^3/3)sin(√3x^2/2), where c1, c2, and c3 are arbitrary constants.
The method of an auxiliary equation is a popular way to solve second-order linear differential equations with constant coefficients. It involves finding the roots of an auxiliary equation, which is found by setting the coefficient of the second derivative equal to zero.
