Answer:
First one: x = 3, and y = 2
Second: 5
Third: Yes because he will have $37.50
Fourth: The numbers 2.5 and 3 will make it true
Step-by-step explanation:
1. 4(3) + 2(2) + 3 = 12 + 4 + 3 = 19
2. 4x + 2 = 22, 4x = 20, x = 5
3. 2.25y + 7.25z + 11.25, 2.25(2) + 7.25(3) + 11.25 = 4.5 + 21.75 + 11.25 = 37.5
He will get $37.50, which is enough.
4. The numbers 2.5 and 3 will make it true: 2(2.5) + 3 = 5 + 3 = 8, 2(3) + 3 = 6 + 3 = 9, the numbers below it won't make it true.

I NEED HELP FAST! Two different pools are being considered for a back yard. How many more feet will the larger pool occupy?
Answer:
138.16ft²
Step-by-step explanation:
Oh boy, this is a long one so hang onto your hats:
We're going to start by finding the area of the smaller circle (or pool) the formula for the area of a circle is pi x radius² and we're given the diameter, here's what we're gonna do:
take the diameter and divide it by 2:
20 ÷ 2 = 10
So now we have the radius and all we have to do is plug that into the formula:
10² = 100
(we're doing 3.14 for pi)
3.14 x 100 = 314
So the area of the smaller circle is 314ft²
Now we gotta do the bigger circle, and since we already have a radius, we can skip a step:
12² = 144
3.14 x 144 = 452.16
So the area of the bigger circle is 425.16ft²
But now we have to find the difference between the two areas:
425.16 - 314 = 138.16
So the larger pool occupies 138.16 more ft² than the smaller pool
lemmie know if this is wrong

What is the median for the data shown below? Test Scores Stem Leaves 6 8 7 0 8 0, 6, 8, 8, 9 6, 6, 7, 7, 8, 8, 9 10 0, 0, 0, 0, 0 6|0 = 60 years old 100 97 92 32
Answer: I believe it would be 0.
Step-by-step explanation:
The median is 97.
Using the stem-and-leaf plot in the diagram, below, write out each data points given, which are:
68, 70, 80, 86, 88, 88, 96, 96, 97, 97, 98, 98, 99, 100, 100, 100, 100, 100
The line plot for these data would have the following frequency for each data point:
68 - 1 dot
70 - 1 dot
80 - 1 dot
86 1 dot
88 - 2 dots
96 - 2 dots
97 - 2 dots
98 - 2 dots
99 - 1 dot
100 - 5 dots
Range = 100 - 68 = 32
Median = 97
Therefore, the median is 97.

Given that cos75º 0.259, which statement below
is also true?
A. sin15º = 0.259
B. sin75° =0.259
C. sin15º = 0.966
D. cos15° =0.259
Alright, lets get started.
Please take a look at the diagram attached.
The reference angle of 75 will be 75
As it is mentioned that the angle intersects the unit circle means r = 1
So, finding cos
cos 75 = [tex]\frac{X}{r}[/tex]
cos 75 = [tex]\frac{0.259}{1}[/tex]
cos 75 = 0.259 is the Answer

A teacher surveys a sample of students from Lake Middle School. He asks the students where they’d like to go for a field trip. He records these results:
80 choose the aquarium.
60 choose the science center.
30 choose the planetarium.
40 choose the farm.
The teacher wants to figure out the relative frequency of a student choosing the aquarium. He will then estimate how many students out of all 1000 at the school are likely to choose the aquarium.
Answer the questions to solve the problem.

Write your answer in the space below.
2. What is the relative frequency of a student choosing the aquarium? Give your answer as a decimal rounded to the nearest hundredth. Show your work.
Write your answer in the space below.
3. Suppose the teacher surveys one student at random. Based on the survey results, what is the estimated probability that the student chooses the aquarium?

ill give thanks and brainliest ;-;
(please i had to repost since a bot answered my last questions, waste of my 20 points
Answer: There are often not more than one or two independent variables tested in an experiment, otherwise it is difficult to determine the influence of each upon the final results. There may be several dependent variables, because manipulating the independent variable can influence many different things.
Two independent variables that could result in a change in the monthly electricity bill are: Physical size of products and Skill level of operators of machines.
Independent VariablesIndependent variables are the determining factors that influence how a dependent variable changes.
For example, monthly electricity bill is a dependent variable which is dependent on the following:
Physical size of productsSkill level of operators of machines.Non-production machines utilizing electricity among others.Therefore, two independent variables that could result in a change in the monthly electricity bill are: Physical size of products and Skill level of operators of machines.

y= -x+21
8.5x + 2.75 (-x + 21) = 132.50
8.5x - 2.75 + 57.75 = 132.50

Answer:
he bought 13 coffee mugs and 8 key chains.
Step-by-step explanation:
How about we solve by simulataneousequation:
consider coffee mug 'x' and key chain 'y'
there are total 21 items,
x+y = 21
=> x = 21 - y .........................(i)
and
total cost is $132.50
8.5x + 2.75y = 132.5 .........(ii)
put value of x from eqn (i) into (ii):
8.5 ( 21 -y) + 2.75y = 132.50
=> 178.5 - 8.5y + 2.75y = 132.50
=> -5.75y = -46
=>y = 8
Put vaklue of y back in (i):
x = 21 - y
=> x = 21 - 8 = 13
thus, x = 13
he bought 13 coffee mugs and 8 key chains.

Write the expression for when you translate the graph of y = |2x|−1 a) one unit up, b) one unit down, c) one unit to the left, d) one unit to the right.
The expression for when you translate the graph of y=|2x|−1 is y= |2x-2|-1.
What is an expression?Expression in mathematics is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division. A function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.
We are given that;
y = |2x|−1
Now,
To write the expression for when you translate the graph of y = |2x| - 1, we need to use the rules for vertical and horizontal shifts. The rules are:
To shift the graph up or down by k units, add or subtract k to the original function.
To shift the graph left or right by h units, add or subtract h to the input variable.
Using these rules, we can write the expressions for each translation as follows:
a) One unit up: y = |2x| - 1 + 1 y = |2x|
b) One unit down: y = |2x| - 1 - 1 y = |2x| - 2
c) One unit to the left: y = |2(x + 1)| - 1 y = |2x + 2| - 1
d) One unit to the right: y = |2(x - 1)| - 1 y = |2x - 2| - 1
Therefore, by the expression the answer will be y = |2x - 2| - 1.
