What is the solution set of \ x|x<-3\ cap\ x|x>5\ ?
Answer:
Let set A = {x|x<-3}
Let set B = {x|x>5}
The solution for set A could be graphically represented with a number line that contained an unshaded circle surrounding the integer -3 and all values to the left or less than -3 would be shaded.
The solution for set B could be graphically represented with a number line that contained an unshaded circle surrounding the integer 5 and all values to the right of 5 or greater than 5 would be shaded.
If you placed the two number lines close to each other, you would see that they do not intersect.
Thus there is no solution for the intersection of set A and set B as defined in the given problem.

Convert 1AA from hexadecimal to decimal.
1AA = 426
What an odd class...
Answer:
426 in decimal.
Step-by-step explanation:
Step 1) Count the digits in 1AA, which in this case is 3 digits, and convert each digit to Hex.
Step 2) Starting from the last number in Step 1, multiply the first number with 1, the second number with 16, and the third number with 256.
Step 3) Add up all the numbers you got in Step 2 to get the answer.
Following the instructions above, your math should look like this:
10 x 1 = 10
10 x 16 = 160
1 x 256 = 256
10 + 160 + 256 = 426
Thus, we got the following answer:
1AA = 426

Find the slope between the points. �. (5, −3) (7, 4)
Answer: slope is [tex]\frac{7}{2}[/tex] or 3.5
Step-by-step explanation:
Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] = [tex]\frac{4-(-3)}{7-5}[/tex] = [tex]\frac{7}{2}[/tex]
Answer:
[tex]\boxed {\boxed {\sf m= \frac{7}{2} \ or \ 3.5 }}[/tex]
Step-by-step explanation:
The slope formula is the change in y over the change in x.
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
In this formula, (x₁, y₁) and (x₂, y₂) are the points given. We are given the points (5, -3) and (7,4). Therefore,
[tex]x_1=5 \\y_1= -3\\x_2=7 \\y_2=4[/tex]
Substitute the values into the formula.
[tex]m=\frac{4--3}{7-5}[/tex]
Solve the numerator.
4 - -3 = 4+3 = 7[tex]m=\frac{7}{7-5}[/tex]
Solve the denominator
7-5=2[tex]m=\frac{7}{2}[/tex]
[tex]m=3.5[/tex]
The slope between the points is 7/2 or 3.5
7. Which of the following illustrates the commutative property of multiplication?
(1) 5(2x) =(5-2)x

Write a paragraph describing the business venture and what kind of algebra or other calculations and formulas might help someone in that endeavor. Also include ways in which the business might operate differently with those tools than without them.
Step-by-step explanation:
A business that offers services to people by providing many amusement and fun with gate fees
The algebraic equations to be used is the general linear equation
Y = MX + C
Where
Y = total income or money realised
M = rate or price rate
X = number of goods or services
C = flat rate or gate fees
The business can also operate differently by using exponential equation
A = P(1 + R%)^t
Where
A = profit
P = capital
R = rate
t = time

-4(3/2x - 1/2) = -15
Answer:
2.8333333333333333333
Step-by-step explanation:
I have high iq
-4(3/2x - 1/2) = -15
Distribute -4
-6x + 2 = -15
Subtract 2 from both sides
-6x = -17
Divide 6 from both sides
x = 2.83333333333333333

Alexander spent a total of 12.5 hours on a science project for the Science Fair. His sister, Laura, spent 16.6 hours on a science project. How many more hours did Laura spend on her project than Alexander spent on his?
Answer:
4.1 I think
Step-by-step explanation:
I just subtracted in my head
Answer:
4.1 hours
Step-by-step explanation:
Laura spent 4.1 more hours on her project than Alexander spent on his. If we split each number into 2 parts (like this: 12.5 -> 12 and .5; 16.6 -> 16 and .6) then we can subtract 12 from 16 and .5 from .6 to get 4 and .1. we add those together to get 4.1

In a school egg drop challenge 136 of the eggs broke out of 200 total what percent of eggs survived the drop ?
To make this equation easier, we can just divide the data by 2, so that the exact number of eggs that survived, is the percentage that survived.
Explanation:
200 = 200 Total Eggs
136 = 136 Eggs That Broke
So, the ratio of eggs that broke to total eggs is:
136 / 200
So, subtract the number of eggs that broke to the total eggs, to find the amount that survived.
200 - 136 = 64
So now we know that, 64 eggs of 200 survived.
Which means, that 32% off the eggs had survived.
