The equation representing when the two planes would be at the same altitude is 9x=486
In terms of mathematics, what is an equation?Equation: A declaration that two expressions with variables or integers are equal. In essence, equations are questions, and attempts to systematically identify the solutions to these questions have been the driving forces behind the creation of mathematics.
From (a) we get that: Altitude of Plane A = 990-18x
Altitude of Plane B = 1476-27x
make 890 - 18x = 1476-27x
-18x+27 x = 1476-890
9x=486
X= 54
so pass 54 seconds will the two plane at the same altitude.

The square of the imaginary number i is -1.
What are imaginary numbers?If you multiply a real number by the imaginary unit I which has the characteristic i2 = -1, you get an imaginary number. The imaginary number bi is squared as -b2. Zero is, by definition, both real and fictional.
A number that results from multiplying a non-zero real number by the iota I is an imaginary number. I in this case Equals (-1) or i2 = -1. Finding the square root of negative integers is made easier by using these values. -4i, 6i, I etc. are some instances of imaginary numbers.

How much will 5% yards cost of fabric be at $10.99 a yard?
If the cost of fabric be at $10.99 a yard, then a 5% yards would cost $0.55
How to determine the cost of the fabric?The given parameters are
Cost of fabric = $10.99 per yard
This means that the unit rate of a yard of fabric is $10.99
So, the cost of a 5% yard cost of fabric would be
Cost = 5% * Cost of fabric
The above equation becomes
Cost = 5% * 10.99
Evaluate the product
Cost = $0.55
Hence, if the cost of fabric be at $10.99 a yard, then a 5% yards would cost $0.55

step by step solution for 4(x-3)=0.5x+2
Answer:
x = 4
Step-by-step explanation:
4(x-3) = 0.5x +2
Multiply both sides by 10
40(x-3) + 5x + 20
Simplify (multiply 40 by x-3)
40x - 120 = 5x + 20
Add 120 to both sides
40x = 5x + 140
Subtract 5x from both sides
35x = 140
Divide 35 on both sides

A truck rental is $30 plus $.40 /mi. Find out how many miles Ken traveled if his bill was $58.80 .
Answer:
72 miles
Step-by-step explanation:
Let x equal the miles Ken travelled; this is what we need to find. Our equation is
$30 + $.40x = $58.80
Subtract $30 from both sides
$.40x = $28.80
Divide both sides by $.40

Which statement is true concerning the vertex and the axis of symmetry of g(x)=5x2−10x?
The true statement concerning the vertex and the axis of symmetry of g(x) = 5x^2 − 10x is that both values are equal
What are quadratic equations?Quadratic equations are second-order polynomial equations and they have the form y = ax^2 + bx + c or y = a(x - h)^2 + k
How to determine the true statement?The equation of the function is given as
g(x) = 5x^2 - 10x
Differentiate the above equation
So, we have
g'(x) = 10x - 10
Set to 0
So, we have
10xx - 10 = 0
Divide through by 10
So, we have
x - 1 = 0
Solve
x = 1
The above is the x coordinate of the vertex and the axis of symmetry

You want to buy an item that costs $100. Which of these is the most cost-effective choice for buying the item?
The most cost-effective choice for buying the item is buying it at a 10 percent discount without sales tax.
A percent discount on a product means that the price of the product is reduced by that percentage.
The full question is that, You want to buy an item that costs $100. Which of these is the most cost-effective choice for buying the item?.
a. using a paid membership card to buy it at a 10 percent discount.
b. buying it online at a 10 percent discount with a $5 shipping charge.
c. buying it at a 10 percent discount without sales tax.
we will calculate the final price in each case to analyze the most cost-effective choice,
In in first case, when using a paid membership card to buy it at a 10 percent discount. we get,
10% of $100 = 10/100×100 = $10
cost = $100 - $10 = $90
On top of this $90 there is the charges of the membership card, therefore the price increases. ( price in first case)
In second case, when buying it online at a 10 percent discount with a $5 shipping charge.
100%-10% = 90%
90% of 100 = $90
Cost: $90 + $5 = $95 ( price in second case)
In third case, when buying it at a 10 percent discount without sales tax.
100% - 10% = 90%
90/100 × 100 = $90. ( price in third case which is minimum as compared to rest of the cases)
Therefore, buying the item at a 10 percent discount without sales tax is the most cost effective method since there is no other cost involved.

Investing for college, Jake originally put $5000 into a savings account that paid 3.5%. There is now $6400 in the account. How long did Jake have the money in the savings account?
Jake put the money in the savings account for about 17.5 years.
Simply explained, a savings account is a place where you can deposit funds and earn interest.
Most people won't pay any tax on their savings interest because it is paid tax-free. Only people with extremely big sums of savings would need to be concerned about this, which is less than 5% of us as basic-rate taxpayers can earn £1,000/year tax-free and higher-rate taxpayers £500.
The interest calculated in a savings account is compound interest:
So let us now calculate the savings rate of interest at 3.5% for the whole time
We know that
[tex]A=P(1+r)^n[/tex]
Where A is the amount , P is the principal , r is the rate and n is the time.
Substituting the values we calculate the value of x.
6400 = 3500 ( 1+0.035 )ⁿ
or, n = 17.54..
So the time required will be about 17.5 years in the savings account.
