The shortcuts for a 30 60 90 triangle is that the:
Hypotenuse is 2 times the short leg
The long leg is √3 times the short leg.
Making it 3 √3
Another way is by the Pythagorean Theorem.
a^2+b^2=c^2
3^2+b^2=6^2
9+b^2=36
Subtract 9 from both sides
b^2=27
Square root both sides
b=5.2 or the √27
√27 can be simplified more
An equation that equals to 27 that has a perfect square is 9*3
√9* √3
The perfect square of 9 equals to 3
So 3 √3

Answers
Given:
A salesperson is paid $10 per week plus $8 per sale.
This week, the salesperson wants to earn at least $250.
To find:
The inequality represents the number of sales, s, the salesperson must make in order to meet that goal.
Solution:
Let s be the number of sales.
Fixed earnings = $10 per week
Earning on 1 sale = $8
Earnings on s sales = $8s
Total earnings = Fixed earnings + Additional earnings of sale
[tex]\text{Total earnings}=10+8s[/tex]
This week, the salesperson wants to earn at least $250. It means, total earning must be greater than or equal to 250.
[tex]10+8s\geq 250[/tex]
[tex]8s\geq 250-10[/tex]
[tex]8s\geq 240[/tex]
Divide both sides by 8.
[tex]s\geq 30[/tex]
Therefore, the inequality [tex]s\geq 30[/tex] represents the number of sales, s, the salesperson must make in order to meet that goal.

Two auto dealers, Winston's and Car-Mart, are measuring how quickly they sell cars. Both dealers sell their cars at a steady rate.
•After 3 days, Winston's has 32 cars left. After 5 days, Winston's has 12 cars left.
•The number of cars at Car Mart is shown in the table.
QUESTIONS:
How many cars per day does Car Mart sell? How did you use the table to find this rate?
How many cars per day does Winston's sell? Explain how you found this rate.
Which dealership sells more cars per day? How many more?
Which dealership started with more cars? How many more cars did that dealership start with? Explain how you found your answer.
Answers
Step-by-step explanation:
Winston's:
After 3 days: 32 cars
After 5 days: 12 cars
Difference in number of cars = 32 - 12 = 20
Difference in number of days: 5 - 3 = 2
Selling rate: 20/2 = 10 cars per day
Car-Mart:
After 2 days: 43 cars
After 3 days: 32 cars
Difference in number of cars = 43 - 32 = 11
Difference in number of days: 3 - 2 = 1
Selling rate: 11/1 = 11 cars per day
Car-Mart sells 1 car per day more than Winston's.
Starting numbers of cars:
Winston's:
Each day less, there are 10 more cars.
Day 3, 32 cars
Day 2, 42 cars
Day 1, 52 cars
Day 0, 62 cars
Winston's started with 62 cars.
Cart-Mart:
Each day less, there are 11 more cars.
Day 2, 43 cars
Day 1, 54 cars
Day 0, 65 cars
Car-Mart's started with 65 cars.
Car-Mart started with more cars. It had 3 more cars than Winston's
Based on the information given in the table, it should be noted that the number of cars that Car Mart sells is 11 cars per day while Winston sells 10 cars per day.
How to solve for the number of cars.The difference in number of cars for Winston will be:
= 32 - 12
= 20
The difference in number of days will be: = 5 - 3 = 2Therefore, the selling rate will be:
= 20/2
= 10 cars per day
The difference in the number of cars for Car-Mart will be:
= 43 - 32 = 11 cars per day.
The difference in number of days will be:
= 3 - 2
= 1
The selling rate will be:
= 11/1
= 11 cars per day
Therefore, Car-Mart sells 1 car per day more than Winston.
Also, the starting numbers of cars for Winston is 62 cars while Car-Mart's started with 65 cars. Therefore, Car-Mart had 3 more cars than Winston's.

Mrs. Farley had 490 buttons. She sewed 7 buttons on a shirt. 8 completed shirts had to be sealed in a box. How many of the shirts sewn were not sealed in a box?
Answers
Answer:
6 of the shirts sewn were not sealed in a box
Step-by-step explanation:
Here, we want to know the number of shirts sewn that were not sealed in a box
Now, if 7 is to be sewn on a shirt, the number of shirts made from 490 buttons will be 490/7 = 70
70 shirts were made
In a box we had 8, so the number of 8’s in 70 will be 8 remainder 6
So what this mean is that 6 of the shirts were not sealed in a box
11/12 - 7/8 in fraction pls help
Answers
Answer:
1/24
Step-by-step explanation:
We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.
So we multiply 11 by 8, and get 88.Then we multiply 7 by 12, and get 84.
Next we give both terms new denominators -- 12 × 8 = 96.
So now our fractions look like this:
88 /96 -84 /96
Step 2
Since our denominators match, we can subtract the numerators.
88 − 84 = 4
So the answer is:
4 /96
Step 3
Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?
To find out, we try dividing it by 2...
Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:
4 /96 ÷ 2 =2 /48
Let's try dividing by 2 again...
Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:
2 /48 ÷ 2 =1 /24
Let's try dividing by 2 again...
No good. 2 is larger than 1. So we're done reducing. There you have it! The final answer is:
11 /12 -7 /8=1 /24
Answer:
1/24
Step-by-step explanation:
Given function:
11/12-7/8Simplifly the denominator:
[tex]\frac{11}{12}=\frac{88}{96}[/tex] [tex]\frac{7}{8}=\frac{84}{96}[/tex]Subtract the fraction term:
[tex]\frac{88}{96}-\frac{84}{96}=\frac{4}{96}[/tex]Simplifly the fraction term:
[tex]\frac{4}{96}=\frac{1}{24}[/tex]Therefore, 11/12-7/8=1/24.

Suppose that the function g is defined, for all real number, as follows.
Answers
Answer:
g(-3) = [tex]\frac{17}{4}[/tex]
g(2) = -3
g(5) = [tex]-\frac{7}{4}[/tex]
Step-by-step explanation:
Let us solve the question
∵ g(x) = [tex]-\frac{3}{4}[/tex] x + 2, x ≠ 2
→ That means we can use it for any value os x except 2
∵ g(x) = -3, x = 2
→ That means we will use it only if x = 2
We want to find g(-3)
∵ x = -3 ⇒ ≠ 2
∴ We will use g(x) = [tex]-\frac{3}{4}[/tex] x + 2
→ Substitute x by -3
∵ g(-3) = [tex]-\frac{3}{4}[/tex] (-3) + 2
∴ g(-3) = [tex]\frac{9}{4}[/tex] + 2
∴ g(-3) = [tex]\frac{17}{4}[/tex]
We want to find g(2)
∵ x = 2
∴ We will use g(x) = -3
→ This is a constant function which means g(2) equal to -3
∴ g(2) = -3
We want to find g(5)
∵ x = 5 ⇒ ≠ 2
∴ We will use g(x) = [tex]-\frac{3}{4}[/tex] x + 2
→ Substitute x by 5
∵ g(5) = [tex]-\frac{3}{4}[/tex] (5) + 2
∴ g(5) = [tex]-\frac{15}{4}[/tex] + 2
∴ g(5) = [tex]-\frac{7}{4}[/tex]

Answers
Answer:
a) $420 b) $399
Step-by-step explanation:
a) $600 = 100%
$60 = 10%
$60 times 3 gives 30% = $180
$600 - $180 = $420
b) $420 = 100%
$42 = 10%
$21 = 5%
this means, they profitted by $21.
so $420 - $21 = $399
therefore, $399 is the cost price
