The age of the father is 42, the age of the son is 9. After how many years will the father be twice as the age of the son?
Answer:
24 years
Step-by-step explanation:
First, I will set up an equation.
2(9 + x) = 42 + x
18 + 2x = 42 + x
x = 24
9 + 24 = 33
42 + 24 = 66
66 is 2 times 33.

In a highway building project, 32 miles of a new highway have been
completed. This is three miles less than one third of the entire length.
How long will the new highway be when completed?
Answer: 105 miles
Step-by-step explanation:
You can write an equation for this problem and solve it.
32 miles=1/3x-3, where x is equal to the total length of the highway.
35=1/3x, and then you multiply by 3, to get x=105
Antonio has just graduated from four years of college. For the last two years, he took out a Stafford loan to pay for his tuition. Each loan had a duration of ten years and interest compounded monthly. Antonio will pay each of them back by making monthly payments, starting as he graduates. Antonio’s loans are detailed in the table below. Year Loan Amount ($) Interest Rate (%) Subsidized? Junior 5,894 6. 9 Y Senior 5,258 7. 5 N Once all of his loans are paid off, what will Antonio’s total lifetime cost be? Round all dollar values to the nearest cent. A. $16,246. 80 b. $17,804. 40 c. $7,593. 16 d. $9,874. 76 Please select the best answer from the choices provided A B C D.
Antonio’s total lifetime cost will be $11680.99 after calculating all loans
What will be Antonio’s total lifetime cost?Given that
Loan Amount ($)
5,894$
5,258$
Interest Rate (%)
6.9%
7.5%
Now for the loan amount 5,894$ at 6.9% interest, the amount will be
[tex]A=P(1+\dfrac{r}{h} )^{n\times t}[/tex]
[tex]A=5894(1+\dfrac{0.069}{12} )^{12\times 10}[/tex]
[tex]A=5894\times(1.00575)x^{120} =11727.76[/tex]
Now for the loan amount 5.258$ at 7.5% interest, the amount will be
[tex]A=5258(1+\dfrac{0.075}{12} )^{12\times 10}[/tex]
[tex]A=5258\times2.1120=111105.23[/tex]
So the total lifetime cost will be
[tex]=11727.76-5894+111105.23-5258=11680.99[/tex]
Thus Antonio’s total lifetime cost will be $11680.99 after calculating all loans

Answer:
8) width = 30 cm
length = 60 cm
9) first side = 60 m
second side = 180 m
third side = 240 m
Step-by-step explanation:
Question 8
Let W = width
Given:
length of a rectangle is 30 cm less than 3 times the width⇒ Length = 3W - 30
Given:
Perimeter = 180 cmPerimeter of a rectangle = 2W + 2L
(where W is the width and L is the length)
Substituting equation for length into the equation for the perimeter and solving for W:
Perimeter = 2W + 2L
⇒ 180 = 2W + 2(3W - 30)
⇒ 180 = 2W + 6W - 60
⇒ 240 = 8W
⇒ W = 30 cm
Substitute found value of W into the equation for length and solve for length:
⇒ Length = 3(30) - 30
⇒ Length = 90 - 30
⇒ Length = 60 cm
Question 9
Given:
The second side is 3 times the first and the third side is 60 m more than the second.Let x = first side
⇒ second side = 3x
⇒ third side = 3x + 60
Given:
Perimeter of triangle = 480 mPerimeter = sum of length of all sides
⇒ 480 = x + 3x + 3x + 60
⇒ 420 = 7x
⇒ x = 60
Therefore,
first side = 60 m
second side = 3 × 60 = 180 m
third side = 3(60) + 60 = 240 m
width be x
length=3x-30
Now
2(3x-30+x)=1804x-30=904x=120x=303x-30=60°#2
sides be x,3x,3x+60
Now
x+3x+3x+60=4807x=420x=60°Hence
3x=1803x+60=240HELP O_O
Find the Roots of the polynomial equation!!!
2x^3+2x^2-19x+20=0
Answer:
Your given polynomial has only one real root which is x= -4
Step-by-step explanation:
find any zero of the polynomial.
x-a divides the polynomial where a is a zero of polynomial:
So x+4 divides [tex]2x^{3} +2x^{2} -19x+20[/tex]
If we factor out a two, we can use the quadratic formula.
2(x^2-3x+2.5) so we have x = (-(-3)+/-(9-4*1*2.5)^(1/2))/2*1)=(3+i) or (3-i)/2 .
Final answer:
[tex]2x^{3} +2x^{2} -19x+20=0[/tex]
then x=-4, (3+i)/2, or (3-i)/2

Only one real zero -1.047If Event A is "the card is a face card" and Event B is "the card is a spade," demonstrate the equation holds true.
/ 52 = / 13 × / 52
The demonstration of the equation is an illustration of probability
The complete demonstration of the equation is:
3/52 = 3/13 * 13/52
How to demonstrate the equationIn a standard deck, we have the following parameters:
Event A = Face card = 12
Event B = Spade =13
Number of cards = 52
So, the probability that a card is a spade and a face card is:
P(A and B) = P(A) * P(B)
This gives
P(A and B) = 12/52 * 13/52
Simplify
P(A and B) = 3/13 * 13/52
Further simplify
P(A and B) = 3/1 * 1/52
Multiply
P(A and B) = 3/52
So, the complete demonstration of the equation is:
3/52 = 3/13 * 13/52

A perfect square is an expression that factors into two other expressions that are identical. The equation that represents this model is (2x)²=4x².
What is a perfect square monomial?
A perfect square is an expression that factors into two other expressions that are identical. A monomial is a single phrase made up of a product of constants, variables, and their positive integer powers. As a result, a perfect square monomial is a monomial that factors into two monomials that are identical.
As given to us that the first row consists of tile 2x², and the second row also consists of tile 2x². Thus, the expression can be written as,
[tex]2x^2+2x^2\\\\=(2x)^2=4x^2[/tex]
