What is the most efficient method for simplifying the expression?
Step-by-step explanation:
To divide exponents, you just have to subtract the exponents from eachother, x^8/x^3, 8 - 3 = 5, so it is x^5
Answer:
You can keep the base same and subtract the exponents since the function asks us to divide.
Step-by-step explanation:
⇒ [tex]\frac{x^8}{x^3}[/tex] = x⁸ - x³
⇒ 8 - 3= 5
⇒ x⁵

Find the perimeter of the figure.
Answer:
97 cm
Step-by-step explanation:
10+3+3+33+33+15=97
Answer:
97 cm
Step-by-step explanation:
Hi there!
The perimeter of a figure is the distance around it. To find P, add all the edge measurements:
P = 10+3+33+15+33+3
P = 13+48+36
P = 61+36
P = 97
Therefore, the perimeter of the figure is 97 cm.

2. Compare the data sets below by finding the range and mean absolute deviation.
Set A: {21, 26, 27, 28, 21, 20, 25, 27, 29, 22}
Set B: {17, 21, 27, 29, 24, 35, 19, 26, 31, 22}
Answer: Set A Range= 9 MAD: 2.88
Step-by-step explanation:
Range is the difference of the largest number and smallest number in a set
MAD: 1) find the mean of the set of numbers (add them, then divide by how many numbers you added together.
2) find the absolute value of each number - the mean you found.
3) find the mean of all the absolute values you found in step 2
*1) 21+26+27+28+21+20+25+27+29+22=246/10=24.6
*2) Absolute value of:
21-24.6= 3.626-24.6= 1.427-24.6= 2.428-24.6= 3.421-24.6= 3.620-24.6= 4.625-24.6= 0.427-24.6= 2.429-24.6= 4.422-24.6= 2.6*3) mean of values from step 2
(3.6+1.4+2.4+3.4+3.6+4.6+0.4+2.4+4.4+2.6)/10= 2.88
MAD=2.88

A kitchen counter will be designed according to the measurements of the diagram in the image. What is the area of the surface of the counter in square feet?
A. 27 ft²
B. 31.5 ft²
C. 36 ft²
D. 40 ft²
can someone help me ?
Answer:
Step-by-step explanation:
a² + b² = c² (pythagorean theorem formula)
let's take 18 as a and 24 as b
So, you'll write it as
18² + 24² = c²
324 + 576 = 900²
c² =810000
c= [tex]\sqrt810000[/tex] = 900
c=900ft

Given the following system of linear equations, do Part A and Part B below.
(3x=3y-3
(y=x+1 Part A: Using the method of your choice (graphing, substitution or addition), find the solution to the system of linear equations. Include all of your work in your final answer. Part B: In two or more complete sentences, explain why you chose the specific method you used to find the solution to the system.
Answer: (0, 1)
Step-by-step explanation:
For starters, the two equations are the same line if you put the first one into y=mx+b form you'll see that they are, so basically any solution to one is the same for the other.
I choose subsitution to find the solution set
[tex]3x = 3y -3\\y = x + 1 \\3x = 3(x+1) -3 \\3x = 3x + 3 -3 \\3x - 3x= 3-3 \\x = 0 \\\\y = x+ 1\\y = 0 +1 \\y = 1[/tex]
This method is the easiest given that the problem already tells you what y is equal to. So this way you can substitute this in for y in the first equation and find x and then from there find y in the second.
Lynn's laptop computer is sitting on top of her desk and is creating an angle. What is a good estimate for the measurement of this angle?
A. 110°
B. 95°
C. 80°
D. 70°
Answer: The most reasonable answer would be B because the Laptop would be facing towards her.
Step-by-step explanation: It couldn't be A because it would be leaning too far, It couldn't be C because the Computer would be facing too low, and it couldn't be D because that would be too low also.

If 90 females and 120 males out of 504 total students get to school by car, what is the relative frequency of females who get to school by car in relation to the total students at the school?
Answer:
0.1786 = 17.86%
Step-by-step explanation:
120 + 90 = 210/504 journey by car
Relative frequency of 90/ 504
= 90/504 =0.178571429
0.1786 = 17.86%
The requried relative frequency of females who get to school by car in relation to the total students at the school is approximately 0.1786 or 17.86%.
What is the relative frequency?Relative frequency is a measure that indicates the proportion or percentage of times an event occurs in relation to the total number of events. It is calculated by dividing the frequency of an event by the total number of events. The result is a decimal or a percentage.
Here,
The total number of students who get to school by car is 90 + 120 = 210.
The relative frequency of females who get to school by car is the number of females who get to school by car divided by the total number of students at the school, which is 504:
90/504 = 0.1786
Therefore, the relative frequency of females who get to school by car in relation to the total number of students at the school is approximately 0.1786 or 17.86%.

Answer:
1. x=5
2. x=3.18
3. x=1.1
4.x=7
5.x=4/5
Step-by-step explanation:
ok so basically what the question means is one number multiplied by another number is this number. for example the first one is 7 multiplied by x (x is a variable so it represents a number) equals 35. you just have to figure out what x equals. and in my opinion, the easiest way to do that is by dividing 35 and 7, which will give you 5. so basically the equation is just 7 x 5 = 35. hope this helps :)
Answer:
1. x = 5
2. x = 3.18181818
3. x = 1.1
4. x = 7
5. x = 0.8
Step-by-step explanation:
1. 35 = 7x now if we divide both sides by 7 we get
35/7 = x
5 = x
2. 35 = 11x divide both sides by 11:
35/11 = x
3.1818181818 = x
3. 7x = 7.7 divide both sides by 7 again:
x = 7.7/7
x = 1.1
4. 0.3x = 2.1 divide by 0.3 on both sides
x = 2.1/0.3
x = 7
5. 2/5 = 1/2x first simplify: 2/5 = 0.4 1/2 = 0.5
0.4 = 0.5x divide both sides by 0.5:
0.4/0.5 = x
0.8 = x

Jose substitutes a value for y in the equation 5y = 3y + 4
How will Jose know if the value is a solution of the equation?
Answer:
Step-by-step explanation:
Equation
5y = 3y + 4
combine like terms 3y becomes negative when moved to the left side being that its positive on the right. 4 has no variable so it stands alone on the right side.
-3y + 5y = 4
After adding a low negative to a high positive number. Turns into 2y.
2y = 4
Divide 2 on both sides to remove the number from the variable on the left.
[tex]\frac{2}{2}[/tex]y = [tex]\frac{4}{2}[/tex]
2 is canceled on the left side which gives the solution for Y.
y = 2
