Find two numbers with a sum of 14 and a difference of 4:
Answer:
First number --> x
Second number --> y
x + y = 14 --> x = 14 - y
x - y = 4
so
14 - y - y = 4
14 - 2y = 4
2y = 10
y = 5
so
x = 14 -5
x = 9
Pedro makes a base monthly salary of $1500. As a vendor, he must sell $20000 worth of items per month. He also makes a 4% commission on all sales beyond the monthly quota. If Pedro sold $26000 worth of items this month, what is his total salary for the month including base salary and commission to the nearest dollar?
Answer:
$2540
Step-by-step explanation:
Given parameters:
Base salary of Pedro = $1500
Amount of commission on sales = 4%
Sales = $26000
Unknown:
His total salary including base salary and commission = ?
Solution:
His total salary;
Total salary = Base Salary + (percent on commission x sales)
Total salary = $1500 + ([tex]\frac{4}{100}[/tex] x $26000)
Total salary = $1500 + $1040
Total salary = $2540

Suppose that 2000 is placed in an account that pays 13% interest compounded each year. Assume that no withdrawals are made from the account. Do not do any rounding.
A:Find the amount in the account at the end of 1 year.
B: Find the amount in the account at the end of 2 years.
The amount will be $2260 in the account at the end of 1 year. The amount will be $2553.8 in the account at the end of 2 years.
What is Compound interest?Compound interest is defined as interest paid on the original principal and the interest earned on the interest of the principal.
A = P(1+r/100)ⁿ
Where:
A = the future value of the investment or loan
P = the principal investment or loan amount
r = the interest rate (decimal)
n = the number of compound periods
As per the question, the given data will be:
p = $2000
r = 13%
t = 1 year
To calculate the amount in the account at the end of 1 year.
A = P(1+r/100)ⁿ
Substitute the values of p,r, and t in the formula,
A = 2000(1 + 13/100)¹
A = 2000(1 + 0.13)¹
A = 2000(1.13)
A = $2260
To calculate the amount in the account at the end of 2 years.
A = 2000(1 + 13/100)²
A = 2000(1 + 0.13)²
A = 2000(1.13)²
A = $2553.8
Thus, the amount will be $2260 in the account at the end of 1 year. The amount will be $2553.8 in the account at the end of 2 years.

Answer:
∠c=90°, ∠b=47.5°, a=85°
Step-by-step explanation:
∠c is inscribing a semicercle so is half of the intercepted arc and the whole circle is 360 , half will be 180 and the angle will be 90°
∠b is inscribing a 95°arc so is half of that 95/2=47.5°
arc a is part of a semicircle so is 180-95 =85°

For the school's sports day, a group of students prepared 12 1/2 litres of lemonade. At the end of the day they had 2 5/8 litres left over. How many litres of lemonade were sold?
Given :
For the school's sports day, a group of students prepared 12 1/2 litres of lemonade. At the end of the day they had 2 5/8 litres left over.
To Find :
How many litres of lemonade were sold.
Solution :
Initial amount of lemonade, I = 12 1/2 = 25/2 litres.
Final amount of lemonade, F = 2 5/8 = 21/8 litres.
Amount of lemonade sold, A = I - F
A = 25/2 - 21/8 litres
A = 9.875 litres
Therefore, 9.875 litres of lemonade were sold.
Hence, this is the required solution.

A rain barrel can hold 72 gallons of water. As it rained last week, water entered the
barrel at a rate of 2 gallons every 6 hours. At this rate, how long will it take the rain
barrel to fill?
(show how you hit the answer if you can)
Answer: Correct me if I’m wrong but I think it’s 216 hours
Step-by-step explanation: every 24 hour you get 8 gallons so do 24 x 10 you get 240 hours and that gets you 80 gallons so you minus 8 gallons so take off 24 hours and you get your answer
What’s the area for this shape??????
Answer:
40cm²
Step-by-step explanation:
The formula of a trapezium is: A=1/2(a+b)h
The values are: a=6, b=10 and h=5
Therefore, to calculate the area: A=1/2(6+10)5
Hence, the area of the trapezium is A=40cm²

Liana is studying the activity of nurse sharks. She starts at a position that is 25 feet below sea level. She rises 9 feet, then descends 12 feet to take a photo of a sleeping shark. Find her position relative to sea level when she took the photo.
Answer:
I believe the answer is -28
Step-by-step explanation
I gotchu bro
The answer is -28 because Liana starts at 25 below sea level (which is the same thing as -25) If she rises 9 feet, then you know to add because she is going up so your just gonna add. Next she descends 12 feet, so she went down, so subtract. So i know the answer is going to be -28 because -25+9 is -16, then imma subtract -16 and 12 so, -16 - 12= -28. There ye go
