Sandy's dad just finished working and was paid $8000 for his work. Her dad gave her mom 5/8 of his salary to pay for household expenses. Her mom gave her brother 1/15 of the amount she received as allowances for her brother. Her brother gave Sandy 2/3 of his allowances because he owed her money. How much money did Sandy get from her brother?
a) Write an equation for this scenario
b) Solve the scenario and find out how much money Sandy got from her brother
Answer:
Sandy got (approximately) $222.22 from her brother.
Step-by-step explanation:
5/8 (8000) = 5000
1/15 (5000) = 333.33
2/3(333.33) = 222.22

Which polynomials are prime? Check all that apply. 15x ^ 2 + 10x - 9x + 7 20x ^ 2 - 12x + 30x - 18 6x ^ 3 + 14x ^ 2 - 12x - 28 8x ^ 3 + 20x ^ 2 + 3x + 12 11x ^ 4 + 4x ^ 2 - 6x ^ 2 - 16
Answer:
15x2+10x-9x+7
8x3+20x2+3x+12
11x4+4x2-6x2-16
Step-by-step explanation:
The prime polynomials are;
⇒ 15x² + 10x – 9x + 7
⇒ 8x³ + 20x² + 3x + 12
⇒ 11x⁴ + 4x² – 6x² – 16
What is an expression?
Expression in math is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Given that;
There are some polynomials.
Now,
Evaluate all options in order to check that the polynomials are prime or not as;
Since, The polynomial is called a prime polynomial if the polynomial has not lower degree factors.
1). 15x² + 10x – 9x + 7
15x² + 10x – 9x + 7 = 5x(3x + 2) - (9x - 7)
Thus, This polynomial can not be factored into lower degree polynomial. Hence, it is a prime polynomial.
2). 20x² - 12x + 30x - 18
20x² - 12x + 30x - 18 = 4x (5x - 3) + 6 (5x - 3)
= (4x + 6) (5x - 3)
Thus, This polynomial is converted into a lower degree polynomial. Therefore, it is not a prime polynomial.
3). 6x³ + 14x² - 12x - 28
6x³ + 14x² - 12x - 28 = 2x² (3x + 7) - 4(3x + 7)
= (2x² - 4) (3x + 7)
Thus, This polynomial is converted into a lower degree polynomial. Therefore, it is not a prime polynomial.
4). 8x³ + 20x² + 3x + 12
8x³ + 20x² + 3x + 12 = 4x² (2x + 5) + 3 (x + 4)
= (4x² + 3) (2x + 5)
Thus, This polynomial can not be factored into lower degree polynomial. Therefore, it is a prime polynomial.
5). 11x⁴ + 4x² – 6x² – 16
11x⁴ + 4x² – 6x² – 16 = x² (11x² + 4) - 2 (x² + 8)
Thus, This polynomial can not be factored into lower degree polynomial. Therefore, it is a prime polynomial.
Therefore, The prime polynomials are;
⇒ 15x² + 10x – 9x + 7
⇒ 8x³ + 20x² + 3x + 12
⇒ 11x⁴ + 4x² – 6x² – 16

Dylan, Alan, Bruce, and Cecil are brothers. Dylan weighs d pounds. Alan weighs 3 pounds more than twice what Dylan weighs. Bruce weighs 12
pounds less than three times what Dylan weighs. If Cecil weighs the same as the combined weight of Bruce and Alan, what is Cecil's welght in
terms of Dylan's weight (d)?
Complete the steps below to solve this problem and others like it.
Part A
Alan weighs 3 pounds more than twice what Dylan weighs. Write an explession to represent Alan's weight in terms of Dylan's weight.
Answer:
Step-by-step explanation:
a=2d+3
b=3d-12
c=a+b so
c=2d+3+3d-12
c=5d-9
Answer:
2d + 3
Step-by-step explanation:
Dylan’s weight is d.
Twice Dylan’s weight is 2d.
Three pounds more than twice Dylan’s weight is 2d + 3.
So, the expression for Alan’s weight in terms of Dylan’s weight is 2d + 3.

A rectangular water tank contains 1440 litres of water. If its length is 120cm and breadth is 80cm, find the height of the water level in the tank.(1 litre=1000cm cube.)
Answer:
Answer is 150cm
Step-by-step explanation:
Here
l = 120cm
B = 80cm
Rectangular tank contain 1440l of water
As as we know 1l = 1000cm^3
So 1440l = 1440000cm^3
Here,
volume of tank( volume of water) = l *b* h
or, 1440000cm^3= 120cm*80cm* h
or, 1440000cm^3= 9600cm^2* h
h = 150cm
volume of tank( volume of water) = l *b* h
or, 1440000cm^3= 120cm*80cm* h
or, 1440000cm^3= 9600cm^2* h
h = 150cm

Step-by-step explanation:
Henry spends $50.00 on lunch, $12.00 on a cap and spends $6.00 on bananas. Hicks spend $120.00 on clothes and $15 on a cap. Henry borrowed money from Hicks to buy his items. In other words, Hicks paid for Henry. Lucky for Hicks he had a discount coupon for 10% off his lunch. Hicks bank account has a balance of $225.
A. How much will the purchase cost him
b. What would Hick’s bank balance be after all the debts were paid?
Answer:
The purchase will cost him $158.
Hick's bank balance would be $67 after all the debts were paid.
Step-by-step explanation:
10% of $50= $5.
$120.00 + $15.00 + $12.00 + $6.00 + 5.00= $158
$225 - $158 = $67
