A rectangular wall is √240 ft by
√50 ft. You need to paint the wall twice to
cover the area with two coats of paint. If
each can of paint can cover 60 square feet,
how many cans of paint will you need?
Answer:
Step-by-step explanation: √240 = 15.49…. √50 = 7.07…
15.5 x 7.07 = 109.58 rounded to 110. Therefore the area is 110 feet so at least 2 can is needed to fill up the wall. But if the problem is being precise it’s 1 can and 5/6 of a can.
2 cans of paint will be needed to cover 110 square feet area.
What is Area of Rectangle?The area of Rectangle is length times of width.
Given,
A rectangular wall is √240 ft by √50 ft.
Need to paint the wall twice to cover the area with two coats of paint.
Area of wall=Length×Width
=√240×√50
=√12000
=109.5=110
Given that each can of paint can cover 60 square feet,
110/60=1.83
=2
Hence, 2 cans of paint will be needed to cover 110 square feet area.

The point only can be on the unit circle and on the second quadrant if:
x = -√55/8
How to get the value of the x-coordinate?
We know that we have a point of the form:
P = (x, y)
And the value of y is:
y = 3/8
Then our point is:
P = (x, 3/8)
And it is on the unit circle, then the values of x and y are solutions of:
x^2 + y^2 = 1
x^2 + (3/8)^2 = 1
x^2 = 1 - (3/8)^2 = 1 - 9/64 =
x^2 = 64/64 - 9/64
x^2 = 55/64
x = ±√(55/64) = ±√55/8
And P is on the second quadrant, then we take the negative option:

Given (x – 7)2 = 36, select the values of x. x = 13 x = 1 x = –29 x = 42
Answer:
Unless you wrote the wrong expressions, non of your choice answers are correct!
Step-by-step explanation:
Solve for x:
2 (x - 7) = 36
Divide both sides of (x - 7)×2 = 36 by 2:
(2 (x - 7))/2 = 36/2
2/2 = 1:
x - 7 = 36/2
The gcd of 36 and 2 is 2, so 36/2 = (2×18)/(2×1) = 2/2×18 = 18:
x - 7 = 18
Add 7 to both sides:
x + (7 - 7) = 7 + 18
7 - 7 = 0:
x = 18 + 7
18 + 7 = 25:
Answer: x = 25

(A) $1800
(B) $540
(C) $1620
(D) $486
The simple interest on $5400 at a rate of 10% per annum for 3 years is $ 1620
Simple interest:The interest on a loan at a fixed rate per annum. The formula used for simple interest is given by
Simple interest (I) = ptr
Where p = principal amount
t = time period
r = rate of interest per year.
Here we have
The sum of $5400 was borrowed from a bank at a rate of 10% per annum for 3 years
Find the simple interest that can be payable
From above observations
Principal amount, P = $5400
Rate of interest = 10% = 10/100 = 0.1
Time period, t = 3 years
The simple interest that can be payable = $5400(3)(0.1) = $ 1620

If you take the 4:3 aspect ratio and divide 4 by 3, the result is 1.33. Therefore, you could alternately describe the 4:3 aspect ratio as 1.33:1, meaning that for every 1.33 units in width, there is 1 unit in height. Again, the same applies for the 16:9.

Friday: Nabil had $80.50 on a gift card before buying four journals at a bookstore. The bookstore charges 50¢ to use the card. He had $44.00 left on the gift card after buying the journals. If each journal cost the same amount, what was the price of each journal?
Answer:
$9.00 a journal.
Step-by-step explanation:
First off, you can start by subtracting $0.50 from $80.50 because it costs $0.50 to use the card.
You’re left with a new value of $80.00. Since Nabil had $44.00 left over on his card, you can subtract $44.00 from $80.00 to figure out how much he spent.
$80.00
-$44.00
————
$36.00
Since Nabil bought four journals, and they are all equal in cost, you can divide $36.00 by 4 (36/4) and get $9.00.

(b) The zeros of the function f(x) are -3, -1, -1, and 1.
(c) The y-intercept is at (0,-3).
What is the endpoint behaviors of a polynomial?
A polynomial function's final behaviour is how its graph behaves as x gets closer to positive or negative infinity. The graph's final behavior is determined by a polynomial function's degree and leading coefficient.
What are zeros of a polynomial?
The locations where a polynomial becomes zero overall are known as the zeros of the polynomial. The term "zero polynomial" refers to a polynomial with a value of zero (-1). The highest power of the variable x is referred to as a polynomial's degree. A linear polynomial is a polynomial with degree 1.
Given function is f(x) = (x+3)(x+1)^2(x-1).
If x = ∞, then f(x) = ∞. The one endpoint of the function will go positive infinity.
If x =- ∞, then f(x) = -∞. The one endpoint of the function will go negative infinity.
To find the zeros of the polynomial, equate f(x) with zero.
(x+3)(x+1)^2(x-1) = 0
Either, x + 3 =0 → x = -3
or, (x+1)^2 =0 → x = -1
or, x-1 = 0 → x = 1
The zeros of the function are -3, -1, and 1.
To find y-intercept, put x=0 in the given function:
f(0) = (0+3)(0+1)^2(0-1)
→ f(0) = -3
The y-intercept is at (0,-3).
The x-intercepts of the function are zeros of the function.

The probability that you win is 6%, and the two choices are dependent events option (B) is correct.
What is probability?
It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
It is given that:
A standard deck of playing cards contains 52 total cards, 13 of which are "spades".
The probability of the first draw:
Probability = favorable outcomes/total outcomes
First draw: 1/4
For the second draw:
Second draw = 12/51
The probability that you win = (1/4)(12/51) = 3/51
