What mistake did Andy make ?
Answer:
The mistake that Andy made was on step 2 when he multiplied only the variables by 12.
Step-by-step explanation:
When you're solving an equation and are multiplying one side by a number, you need to multiply the other side by that number as well to keep the equation true. Since Andy multiplied only the variables and not the constants on each side of the equation, that means the equation would no longer be valid, and solving it would provide a wrong answer.
Answer:
person above me is right. that's is the answer.

102 + 150 + 41 > 500
Answer:
False
Step-by-step explanation:
102 + 150 + 41 > 500
252 + 41 > 500
293 > 500
Is 293 greater than 500?
It is not so this statement is false.
Answer:
That statement is FALSE
Step-by-step explanation:
102+150+41 = 293
293 < 500, not 293 > 500
The statement is FALSE.
The volume V (in cubic feet) of a right cylinder with a height of 6 feet and radius r (in feet) is given by V=6πr2 . Solve the formula for r . Then find the radius of the cylinder when the volume is 1206 cubic feet. Round your answer to the whole number.
Answer:
a) r = √V/6π
b) r = 8 inches
Step-by-step explanation:
a) The volume V (in cubic feet) of a right cylinder with a height of 6 feet and radius r (in feet) is given by V=6πr2 . Solve the formula for r .
Solving for r means making r the subject of the formula
= V=6πr²
Divide both side by 6π
V/6π = 6πr²/6π
r² = V/6π
r = √V/6π
b) Then find the radius of the cylinder when the volume is 1206 cubic feet. Round your answer to the whole number.
r = √V/6π
V = 1206 ft³
r = √1206/6π
r = √(63.98028712294193)
r = 7.9987678503 inches
Approximately r = 8 inches
29% of a university's freshman class are majoring in Economics. If 870 students in the freshman class are Economics majors, how many students are in the freshman class?
need this turned In by 12:00 AM est so please answer quickly!
Answer:
3000
Step-by-step explanation:
[tex]\frac{870}{x} =\frac{29}{100} \\\\29x=87000\\x=3000[/tex]
Double check:
29% = 0.29
3000(0.29) = 870
So 29% of the 3000 freshmen students taking economic majors are 870 students.

Answer:
4,5,6
Step-by-step explanation:
*The sign of ≥ means that it must be greater or equal to 10 in this case
1). 3 isn't a possible solution due to 9 being less than 10
3+6_10
9_10
9<10
2). 4 is a possible solution due to the sum of 4 and 6 being equal to 10
4+6_10
10_10
10=10
3). 5 is a possible solution due to the sum of 5 and 6 being larger than 10
5+6_10
11_10
11>10
4).6 is a possible solution due to the sum of 6 and 6 being larger than 10

A six sided die is rolled and the spinner on the right is spun.What is the probabiliy of rolling a 6 and spining a vowel
Kindly note that the spinner diagram. Wasn't given and the spinner used was just hypothetical.
Answer:
1 /18
Step-by-step explanation:
Sample space for spinner = (a, b, c, d, e, F, G, h, I) = 9
Total possible outcomes = sampme space
Vowels in spinner = (a, e, I)
Number of vowels = required outcome = 3
P(spinning a vowel) = required outcome / Total possible outcomes
P(spinning a vowel) = 3 / 9 = 1/3
For a six sided dice ;
Required outcome = (6) = 1
Total possible outcomes = (1,2,3,4,5,6) = 6
P(rolling a six) = 1/6
P(rolling a 6 and spinning a vowel) = 1/3 * 1/6 = 1/18

1. Find the slant height of a square pyramid with a surface area of 57 square feet and a base perimeter of 12 feet
Answer:
Slant height = 8 feet.
Step-by-step explanation:
If the perimeter of the square base = 12 then each side of the base = 12/4
= 3 feet and its area = 3*3 = 9 ft^2
The area of one of the triangular sides = 1/2 * 3 * h where h is slant height.
So total surface area = 57 = 9 + 4 * 1.5h
9 + 6h = 57
6h = 48
h = 8 feet.

Answer:
10.125 ft^2
Step-by-step explanation:
Our strategy will be to find the area of each shape, therefore finding the area of each rectangle and the triangle, and then adding all the areas together. So, for the leftmost rectangle, the area is 1.5 ft x 3 ft = 4.5 ft. For the bottom rectangle, the area is the same, due to it having the same side lengths. For the triangle, we can find the area using A = (1/2) x base x height. The base and height are both 1.5, due to them being sides of the two rectangles. Therefore, the area is 1.5 x 1.5 x (1/2) = 1.125. Then, to get the total area we have to add up the areas we've already calculated. Therefore 4.5 + 4.5 + 1.125 = 10.125 ft^2

If b is a perfect square, which represents the solutions to the equation?
HELP PLEASE
Answer:
[tex]\{\sqrt b, -\sqrt b\}[/tex]
Step-by-step explanation:
Given
[tex]a^2 - b = 0[/tex]
Required
Determine the solution
Since b is a perfect square, the equation can be expressed as:
[tex]a^2 - (\sqrt b)^2 = 0[/tex]
Apply difference of two squares:
[tex](a - \sqrt b)(a + \sqrt b) = 0[/tex]
Split:
[tex](a - \sqrt b)= 0 \ or\ (a + \sqrt b) = 0[/tex]
Remove brackets:
[tex]a - \sqrt b= 0 \ or\ a + \sqrt b = 0[/tex]
Make a the subject in both equations
[tex]a =\sqrt b \ or\ a =-\sqrt b[/tex]
The solution can be represented as:
[tex]\{\sqrt b, -\sqrt b\}[/tex]

which set has the largest range?
Answer:
B
Step-by-step explanation:
Answer:
B has the largest range
Step-by-step explanation:
Definition: The range is the difference between the highest and lowest values.
So we must gather the greatest and the least the subtract to find the difference.
A. {2, 3, 5, 5, 5, 15}
15-2=13. Range for A is 13
B. {10, 20, 30}
30-10= 20. Range for B is 20
C. {140, 141 ,142 ,143}
143-140= 3. Range for C is 3
D. {40, 40, 40, 40, 40}

Use the inverse trigonometric keys on a calculator to find the measure of angle A
Answer:
49°
Step-by-step explanation:
49^2 - 32^2 = BC^2
2401 - 1024 = 1377
√1377 = 37.1079506
37.1 m
Sin(A) / 37.1 = Sin(90)/ 49
Sin (A) = 37.1 X Sin(90)/49
A = sin^-1(3.71 X sin90)/49
A = 49.21
