x+y=20 3x-3y=30 Which values of x and y satisfy this system of equations?
x +y = 20 ( rewrite as x = 20-y)
3x - 3y =30
3(20-y) - 3y = 30
60-3y - 3y = 30
60-6y = 30
-6y = -30
y = -30 / -6 = 5
x=20-5 = 15
x = 15, y = 5
Farmer Tom raises ducks and horses on his farm. All of his horses need new horseshoes. He calls the farrier (a person who puts shoes on horses) but has a difficult time remembering how many of each animal he owns. He knows that there are a total of 24 animals. The animals have a total of 62 legs (all animals have either two or four legs). How many horses does Tom own?
h+d=24
h = 24-d
4h +2d = 62
4(24-d) +2d = 62
96 -4d +2d =62
96-2d =62
-2d =-34
d =-34/ -2 = 17
17 ducks
24-17 = 7 horses
Consider the function represented by the graph. What is the domain of this function
Answer: The answer is [tex]\{x:x\geq 0\}.[/tex]
Step-by-step explanation: We are given a graph that represents a function. We are to find the domain of the graphed function.
Domain and Range: If y=f(x) is a function, then the domain is the set of all first elements of ordered pairs (x-coordinates) and the range is the set of all second elements of ordered pairs (y-coordinates).
In the given graph, 'x' takes the values from 0 to infinity and 'y' takes the values from negative infinity to 9.
Therefore, domain of the function is [0, ∞) and the range is (-∞, 9).
Thus, the domain is given by the set [tex]\{x:x\geq 0\}.[/tex]

Name a pair of adjacent complementary angles
In geometry, complementary angles are two angles whose measures add up to 90 degrees. A pair of adjacent complementary angles could be 30 degrees and 60 degrees.
Explanation:In geometry, complementary angles are two angles whose measures add up to 90 degrees. For example, if one angle measures 30 degrees, the other angle measures 60 degrees because 30 + 60 = 90. So, a pair of adjacent complementary angles could be 30 degrees and 60 degrees.

Triangle MNP is the image of triangle JKL after a 120 degrees counterclockwise rotation about point Q. If the measure of angle L is 47 degrees and the measure of angle N is 57 degrees, determine the measure of angle M. Explain how you arrived at your answer.
The measure of angle M in triangle MNP is 76 degrees. This is determined by utilizing the sum of interior angles property of triangles and understanding the correspondence of angles in rotated or transformed figures.
Explanation:The problem given is associated with the geometry of triangles. From the problem statement, we know that triangle MNP is the image of triangle JKL after 120 degrees counterclockwise rotation. This indicates that the angles of both triangles are the same. Hence, angle M will correspond to angle J of the original triangle.
However, since we are not given the measure of angle J, we need to calculate it using the property of triangles. In triangles, the sum of the interior angles amounts to 180 degrees. Therefore, the measure of angle J can be found by subtracting the measures of the other two angles (angle K and angle L) from 180 degrees.
Given the measure of angle L is 47 degrees and the measure of angle N (which corresponds to angle K in triangle JKL) is 57 degrees, we use the equation:
Angle J = 180 - (angle K + angle L) = 180 - (57+47) = 76 degrees.
Thus, the measure of angle M in triangle MNP, which is corresponding to angle J in triangle JKL, is 76 degrees.

There is a sales tax of $6 on an item that costs $93 before tax. A second item costs $294.50 before tax. What is the sales tax on the second item?
Answer:
its 19
Step-by-step explanation:
If a second item costs $294.50 before tax. The sales tax on the second item will be $19.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
It is given that, there is a sales tax of $6 on an item that costs $93 before tax. A second item costs $294.50 before tax.
We have to apply the ratio as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
$6/$93 = t/$294.5
t = 6 × 294.5 / 93
t = $ 19
Thus, if a second item costs $294.50 before tax. The sales tax on the second item will be $19.

Find the z-score such that the area under the standard normal curve to the right is 0.370.37. loading... click the icon to view a table of areas under the normal curve. the approximate z-score that corresponds to a right tail area of 0.370.37
Using the standard normal table, it is found that the z-score is z = 0.33.
-------------------------
In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the standard normal table and find the p-value associated with this z-score, which is the percentile of X. This p-value is the left-tailed area.The right-tailed area is 1 subtracted by the p-value.In this problem:
Right-tailed area of 0.37, thus the p-value is of 1 - 0.37 = 0.63.Looking at the standard normal table, the z-score is z = 0.33.A similar problem is given at https://brainly.com/question/7001627
