Answer:
X = 11/36
Step-by-step explanation:
First, find the common denominator of the fractions and convert them.
(4/9) x 4 = 16/36
(3/4) x 9 = 27/36
X + 16/36 = 27/36
Now you can solve for X
X = 11/36
The fraction cannot be simplified

the largest perfect square number that is a factor of 75 is?
the largest perfect square number that is a factor of 32 is?
the largest perfect square number that is a factor of 68 is?
Answer:
Step-by-step explanation:
75 = 3 x 25 = 3 x 5²
32 = 2 x 16 = 2 x 4²
68 = 4 x 17 = 2² x 17
So
the largest perfect square number that is a factor of 75 is 25
the largest perfect square number that is a factor of 32 is 16
the largest perfect square number that is a factor of 68 is 4
When six times the larger of two numbers is added to seven times the smaller, the result is 114. Ten times the larger less nine times the smaller is 66. Determine the numbers.
Answer:
Step-by-step explanation:
Let the larger number = x
Smaller number = y
6x + 7y = 114 ------------(I)
10x - 9y = 66 ------------(II)
Multiply equation (I) by 9 and multiply the equation (II) by 7. After that add the two equations. So that, y will be eliminated and we can find the value of x
(1)*9 54x + 63y = 1026
(II)*7 70x - 63y = 462 {Now add}
124x = 1488 {Divide both sides by 124}
x = 1488/124
x = 12
Plugin x = 12 in any of the equation. Here, We are substituting in equation (I)
6*12 + 7y = 114
72 + 7y =114
7y = 114 - 72
7y = 42
y = 42/7
y = 6
The numbers are 12 , 6

in each linear equation identify the slope (m) and the y-intercept (b)
Answer:
a is D and b is C
Step-by-step explanation:
Slope is always with an x, b is always alone
Hey there!
Please remember that
in slope-intercept form, m is the slope, and b is the y-intercept.Is y=4x-5 written in slope-intercept form (y=mx+b)? Sure! :)
Therefore, the slope, m, is 4, and the y-intercept, b, is -5.
Same with the second equation:
y=2/3-x
or
y=x-2/3
here, the y-intercept, b, is 2/3, and the slope, m, is -1.
Now, what's the equation of the line with a slope of 2 and a y-intercept of -7?
That's right, y=2x-7.
Hope everything is clear.
Let me know if you have any other questions!

A^2 = 4 and B^2 = 3. What is C^2 × 15?
Answer:
105
Step-by-step explanation:
Assuming A^2 + B^2 = C^2:
C^2 = 4 + 3 = 7
So,
C^2 * 15 = 49(15) = 105
Note: Since the relationship between A, B, and C isn't known, it cannot be said for certain that 105 is the answer.
Step-by-step explanation:
there is no C in the first 2 equations. There is no A or B in the last expression. I do not think you can solve this.

Maggie keeps track of daily bird sightings. The table shows the number and types of swans that were seen in one day.
Types of swans:
Mute swans 5
Trumpeter swans 34
Tundra swans 2
Maggie incorrectly says that the percent of mute
swans is equivalent to 5
36. Explain her likely error.
What percent of the swans were mute swans? Round to the nearest
whole percent.
Answer:
first we need to add all of the swans together, then from there you take the amount of mute swans and divide it by the sum of all the swans! finally, multiply by 100 to convert into a percent and round it to 12.2%
Step-by-step explanation:
Answer:
8%
Step-by-step explanation:
First, add the total of all the swans together
5+34+2=41
Next, take the total and divide it by the number of mute swans there are
41÷5=8.2
Finally round 8.2 to the nearest whole percent
8.2=8
The answer is 8%
Aplumber charges a $75 flat fee for jobs lasting up to an hour and $30 for each hour of labor after the first hour. Which
expression models the cost of a job lasting h hours, when h is greater than 1?
O 75-30h
O 75+ 30(h-1)
O 75h+30
75(h-1)+30
[tex]\longrightarrow \sf 75+ 30(h-1) [/tex]
Solution:-Given that :-
job last for h hours Cost of job lasting more than 1 hour = $30Cost for the first hour = $75[tex]\leadsto[/tex]Remaining hours for which the job will last after first hour= (h-1)
Therefore,
Cost for subsequent hours = 30×(h-1)
= 30(h-1)
Total Cost for job = Cost for 1st hour + Cost for subsequent hours

It is part of the given information.
It is part of the argument.
It is the conclusion.
It is an assumption.
Answer:
It is part of the argument.

Jerry, Skyler and Kyle were measuring the tank (cylinder) for storing water tower on the hill. Working together Jerry and Skyler
determine the circumference was approximately 295.3 feet. Kyle measured the height to be about 40 feet. What is the potential
volume of the tank? (Round to the nearest tenth)
Answer?
Answer:
277 591.1 ft³
Step-by-step explanation:
First, use the formula for circumference to solve for the diameter.
Circumference = πd
295.3 = πd
295.3/π = d
94 ft = d
Then, divide the diameter by 2 to find the radius.
r = d/2
r = 94/2
r = 47 ft
Now, use the value of the radius with the given height in the formula for volume of a cylinder.
V = πr²h
V = π(47²)(40)
V = 277 591.1 ft³

Write an expression that represents the height of a tree that began at 6 feet an increases by 2 feet per year. Let y represent the number of years
Answer:
Yes.
Step-by-step explanation:
The expression 2y + 6 could be used to denote the tree's height.
What is an expression?A number, a variable, or a mixture of numbers and variables, along with operation symbols, make up an expression. Two expressions joined by an equal sign form an equation.
Given, the height of a tree that began at 6 feet and increases by 2 feet per year. Let y represent the number of years
Expression = 2y + 6
Since the height of the tree starts at 6 feet thus positive 6 would be constant and it increases by 2 feet every year thus 2 would be the multiple of the variable that is y.
therefore, an Expression that represents the height of the tree would be 2y + 6.

A piñata is a container filled with candy and is broke by hitting it with a stick. The probability that Amanda will break a piñata on her first his is 0.58. She will continue to hit the piñata until it breaks. If she does not break the piñata on a particular hit, the piñata is weakened and the probability that she will break it on the next hit is 0.14 greater than the probability on the previous hit. For example, if the piñata does not break on the first hit, the probability that it will break on the second hit is 0.72 (found by 0.58 + 0.14 = 0.72). Calculate the probability that Amanda does not break the piñata on the first hit and does break the piñata on the second hit
Answer:
0.3024
Step-by-step explanation:
Given the following :
Probability of breaking pinata on first hit = 0.58;
P(first hit break) = 0.58
P(does not break on first hit) = 1 - p(first hit break) = 1 - 0.58 = 0.42
P(2nd hit break) = p(first hit break) + 0.14 = 0.58 + 0.14 = 0.72
Hence, Calculate the probability that Amanda does not break the piñata on the first hit and does break the piñata on the second hit
P(does not break on first hit) * p(2nd hit break)
0.42 * 0.72 = 0.3024

In the figure, parallel lines r and s are cut by line t
What is the value of x in this figure?
Answer:
x = 49
Step-by-step explanation:
Since the line is parallel, the value of 2x - 8 is equal to 90.
=> 2x - 8 = 90
=> 2x = 98
=> x = 49
Answer:
x = 49
Step-by-step explanation:
2x - 8 and the right angle are corresponding angles and are congruent , then
2x - 8 = 90 ( add 8 to both sides )
2x = 98 ( divide both sides by 2 )
x = 49

The graph of f(x) shown below
Answer:
C
Step-by-step explanation:
the "-" sign can't be true, because that would have turned the whole graph of x² upside-down. but it is not.
so, we need a positive sign for the x term.
and the whole graph is shifted to the right. so the functional value of x of F(x) is now the same that happened "earlier" (for smaller x) with G(x). so, the argument "x" is now reduced (by 3 units, as the graph is shifted right by 3 units) in the calculation compared to the original G(x) calculation.
therefore, the ...(x-3)... expression is right.
so, positive sign and "(x-3)" is only in C.

Rewrite (123 + 456) + 789 using the Associative Law of Addition
Answer:
123 + (456 + 789)
Step-by-step explanation:
since this is an addition problem, the parenthesis don't matter, and they can be put wherever you want.
(123 + 456) + 789
123 + 456 + 789
(123 + 456 + 789)
123 + (456 + 789)
technically, any of these would work, but I think the kind of answer the problem is looking for is;
123 + (456 + 789)
