Answer: 44%
Step-by-step explanation:
Area of the first hole = 30 × 30 = 900
Area of second hole = (30+6) × (30+6) = 36 × 36 = 1296
Percentage increase = (1296 - 900) / 900 × 100
= (396 / 900) × 100
= 44%

Answer:
3
Step-by-step explanation
you have to do (2^3)(a^4*3)(b^2*3) which gets you 8a^12b^6
then you have (8a^12b^6)*(3ab^4) so you do (8*3)(a^12+1)(b^6+4)
which equals 24a^13b^10
and therefore the answer is 3

20% of Aussies have blue
eyes. If 4 Aussies in a play
group have blue eyes, how
many Aussies are in the
group?
Please help
Answer:
20
Step-by-step explanation:
Step 1: 4 = 20% × Y
Step 2: 4 = 20/100 × Y
Multiplying both sides by 100 and dividing both sides of the equation by 20 we will arrive at:
Step 3: Y = 4 × 100/20
Step 4:Y = 4 × 100 ÷ 20
Step 5: Y = 20
The number of Aussies in the group is 20
What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Given data ,
Let the total number of Aussies in the group be = A
The number of Aussies in the group who has blue eyes = 4
The percentage of Aussies that have blue eyes = 20
So , the percentage equation is
20 percentage of total number of Aussies have blue eyes = 4
And ,
( 20 / 100 ) x A = 4
Multiply by 100 on both sides , we get
20A = 400
Divide by 20 on both sides , we get
A = 20
Therefore , the value of A is 20
Hence , the total number of Aussies in the group is 20

Answer:
19-37=18
18÷3=6
she scored (6) 3-points
Answer:
4
Step-by-step explanation:
what you would do is 19-3 and get 16 then add 3 until you get 37. you would have to cout how many times you counted up 3, here we go,16,19,21,24,27,30,33,36 we have a remainder but she made 8 shots. so since we are 1 short we have to divide by 2 to get 4.

The required zero that has not significant is 100, 10.0, and 1.30.
Given that,
To determine the number that has zeros that are not significant.
A number system is described as a technique of composing to represent digits. It is the mathematical inscription for describing numbers of a given set by using numbers or other characters in a uniform method. It delivers a special presentation of every digit and describes the arithmetic structure.
Here,
Zeros between non-zero numbers are significant.
So it contains 2.05,
Zeros to the left of the first non-zero digit are not significant.
It contains 100, 10.0. and 1.30
Thus, the required zero that has not significant is 100, 10.0 and 1.30

Answer:
n=10
Step-by-step explanation:
first distribute
-3 + 1/2 n = -1/2n + 7
next multiply both sides of the quation by 2
-6+n=-n+14
add n to both sides
-6+n+n=14
add 6 to both sides
n+n=14+6
combine like terms
2n=20
divide both sides by 2

Answer:
A
Step-by-step explanation:
Use POE, none of the answer makes any sense
Answer: The correct answer would be A
Step-by-step explanation:
This question asks us what equation could represent the scatter plot. While we may not be looking for an exact line of fit we want one that can best represent the data that we have. While I would highly recommend graphing each equation as it would give you a much greater understanding of the material you can also piece together a correct answer just by looking at the equations. First of all, by looking at the graph we can tell that the slope is negative because as we progress along the x axis the values on the y axis get lower and lower meaning that we have a downward sloping line. This immediately narrows out D because we can see that there is no - sign before the 9x which represents the slope. We can also narrow out B right away as the slope is too extreme for our scenario. A slope of -3 means that it would have to be a lot more vertical than we see represented in this scatter plot. -3 means that the line would have to go down 3 units for every 1 unit it horizontally moves if that makes sense. Now we are left with two possible answer choices, A and C. We can now look at the y intercept point of these equations to determine the best answer. The y intercept is the point at which the line crosses the y axis. C has a y intercept of 1 and we see the scatter plot points congregate much higher on the y axis than 1 so that rules out that answer leaving us with A! Just to double check our answer we know a slope of -3/4x seems reasonable based on the previous information and we can certainly see that a y intercept of 10 would make sense! I hope this has been of use to you and please do not hesitate if you have anything you would like me to elaborate on :) Have a wonderful rest of your day!
Use rectangle ABCDIf mzBAC = (4x + 5)º and m CAD = (5x - 14)°, find m2CAD.
Answer:
m CAD is 41°
Step-by-step explanation:
The angles in a rectangle are 90 degrees each as the sides are perpendicular. A such, given that mzBAC = (4x + 5)º and m CAD = (5x - 14)°, then
4x + 5 + 5x - 14 = 90
Rearrange the equation
4x + 5x + 5 - 14 = 90
9x - 9 = 90
Collect like terms
9x = 90 + 9
9x = 99
Divide both sides by 9
x = 99/9
= 11
Recall that m CAD = (5x - 14)°
Substitute the value of x into the expression
Hence
m CAD = (5*11 - 14)°
= (55 - 14)°
= 41°

so say that you have 59$ as a flat cost do when you have a problem like this its kinda easy but what you are going to do is take 59 and divide 5 and see what you get you are going to get 11.8 then divide 11.8 into 70 and see what you get then lets see you would get a number that is a fraction answer sis at top.

Does anyone know this if you could help me I would appreciate it
Answer:
C, B
Step-by-step explanation:
Basically to find the slope you take the rise over run. How many squares does the line go up, over how many does it go left or right. As you can see in the diagram, it goes up 2 squares and goes left 1 square, giving the slope 2/1, which is 2.
The slope of a horizontal line is straight, which means it goes up 0, so automatically your answer is zero, because dividing anything by 0 is 0.
