Answer:
2x60, 4x30
Step-by-step explanation:
Given that the glee club has 120 cupcakes to sell.
These 120 cupcakes are to be arranged in a rectangle shape such that
there are even number of cakes lengthwise and even number of cakes breadthwise.
If l is the number of cakes along row, and m is the number of cakes along column, then we have both l and m as even.
Also lm=120
In other words, we must find 2 even factors of 120 l and m such that lm = 120
2x60 is one such pair
Next is 4x30.
There cannot be any other pair satisfying this condition.
Hence answer is 2x60 or 4x30
The length of a rectangle room is 6 feet longer than twice the width. If the room's perimeter is 132 feet, what are the room's dimensions?
Answer:
The width of the room is 20 feet.
The Length of the room is [tex]46[/tex] feet.
Step-by-step explanation:
Lets take the width of the room as [tex]x[/tex] feet
Then the length of the room will be [tex]2x+6[/tex] feet
Perimeter of a room is the addition of all the walls making the boundary of the room.
Perimeter of the rectangular room = 2 * Width + 2 * Length
⇒[tex]132=2*x+2*(2x+6)[/tex]
⇒[tex]132=2x+4x+12[/tex]
⇒[tex]132=6x+12[/tex]
⇒[tex]132-12=6x[/tex]
⇒[tex]120=6x[/tex]
⇒[tex]20=x[/tex]
Therefore,
The width of the room is 20 feet.
The Length of the room is,
[tex]2x+6[/tex] = [tex]2*20+6[/tex] = [tex]46[/tex] feet
Perform the indicated operation and then simplify 4m-3-9m+8

9x^4−64y^2
To factor 9x^4 - 64y^2, use the difference of squares formula. The factored form is (3x^2 + 8y)(3x^2 - 8y).
To factor 9x^4 - 64y^2, we can use the difference of squares formula: a^2 - b^2 = (a + b)(a - b). Applying this, we get: 9x^4 - 64y^2 = (3x^2 + 8y)(3x^2 - 8y)
Therefore, the factored form of 9x^4 - 64y^2 is (3x^2 + 8y)(3x^2 - 8y).

The vertex of this parabola is at (3,-2). when the x-value is 4, the y-value is 3. whatis the coefficient of the squared expression in the parabolas equation
Answer:
The coefficient of the squared expression in the parabolas equation will be 5.
Step-by-step explanation:
The vertex form of parabola is: [tex]y=a(x-h)^2 +k[/tex] , where [tex](h,k)[/tex] is the vertex point and [tex]a[/tex] is the coefficient of [tex]x^2[/tex] term.
The vertex is given as [tex](3,-2)[/tex]. That means, [tex]h=3[/tex] and [tex]k=-2[/tex]
So, the vertex form will be: [tex]y=a(x-3)^2-2[/tex]
Given that, when the x-value is 4, the y-value is 3. So, plugging these values into the above equation, we will get.....
[tex]3=a(4-3)^2-2\\ \\ 3=a(1)^2-2\\ \\ a=3+2=5[/tex]
Thus, the coefficient of the squared expression in the parabolas equation will be 5.
A car is purchased for $29500. After each year, the resale value decreases by %35. What will the resale value be after 4 years
Using the exponential decay formula, the resale value of a car initially purchased at $29,500 and depreciating at 35% per year will be approximately $5,266.08 after 4 years.
To calculate the resale value of a car after depreciation, we can use the formula for exponential decay, which is [tex]V = P (1 - r)^t[/tex], where V is the future value of the car, P is the initial purchase price, r is the rate of depreciation, and t is the time in years. In this case, P = $29,500, r = 35% or 0.35, and t = 4 years.
Following the formula, the resale value after 4 years would be:
V = $29,500 (1 - 0.35)⁴
V = $29,500 (0.65)⁴
V = $29,500 (0.17850625)
V = $5,266.08 approximately
Therefore, the resale value of the car after 4 years will be around $5,266.08.
What is the length of the hypotenuse of the triangle of 7ft and 4ft
To find the length of the hypotenuse in a right-angled triangle with sides measuring 7ft and 4ft, use the Pythagorean Theorem: 7² + 4²= c², which gives us the hypotenuse length of approximately 8.06 feet.
The question is asking for the length of the hypotenuse of a right-angled triangle when the lengths of the other two sides are known (7ft and 4ft).
To find the hypotenuse, we use the Pythagorean Theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b). The formula is expressed as a² + b² = c².
By applying the Pythagorean Theorem:
72 + 42 = c²
49 + 16 = c²
65 = c²
c = √65 ≈ 8.06 ft
Therefore, the length of the hypotenuse is approximately 8.06 feet.

Perpendicular to y=-1/3x+1
Passes through (5,-2)
How do I solve this??
Answer:
y = 3x - 17
Step-by-step explanation:
Here is the point-slope form of the equation of a line.
[tex] y - y_1 = m(x - x_1) [/tex]
If you are given a slope, m, and a point on the line, (x1, y1), you just plug in the values into the equation above, and you get the equation of the line.
In your problem, you are given a point on the line, (5, -2). Now you need the slope of the line. Your line is perpendicular to the given line. The slopes of perpendicular lines are negative reciprocals. If you know the slope of a line, the slope of its perpendicular is found by flipping the fraction and changing the sign.
The given line has slope -1/3.
Flip -1/3 to get -3.
Now change the sign to get 3.
The slope of the line you need is 3. The line passes through point (5, -2).
Now we use the point-slope equation and we plug in the values we have.
[tex] y - y_1 = m(x - x_1) [/tex]
[tex] y - (-2) = 3(x - 5) [/tex]
[tex] y + 2 = 3x - 15 [/tex]
[tex] y = 3x - 17 [/tex]

Which of the following are measures of complementary angles? A. 50° and 41° B. 100° and 80° C. 77° and 13° D. 35° and 10°
Complimentary angles equal 90 degrees. So the answer would be C because 77+13= 90.
Answer: Two angles are complementary when they add up to 90°
then, doing all the options:
A) 50° + 41° = 91°, so this angles are non complementary.
B) 100° + 80° = 180°, so this aren't complementary, but they are Supplementary (because their addition is 180°) angles.
C) 77° + 13° = 90°, si this angles are complementary
D) 35° + 10° = 45°, this pair is not complementary.
So the only correct answer is C.
what is the solution of 3x+8/x-4 >;= 0
The division between two numbers is positive if and only if they have the same sign. So, this fraction is positive if numerator and denominator are either both positive or both negative.
For this reason, you want to study the sign of numerator and denominator separately first.
As for the numerator, you have
[tex] 3x+8 \geq 0 \iff 3x \geq -8 \iff x \geq -\dfrac{8}{3} [/tex]
Similarly, for the denominator you have
[tex] x-4 > 0 \iff x > 4 [/tex]
(note that we used strict inequality for the denominator, since it can't be zero).
So, the sign of the fraction works like this:
If [tex] x \leq -\frac{8}{3} [/tex] both numerator and denominator are negative (or, at most, the numerator is zero if [tex] x = -\frac{8}{3} [/tex]), so the ratio is greater than or equal to zero.If [tex] -\frac{8}{3} \leq x < 4 [/tex] the numerator is positive and the denominator is negative (or, at most, the numerator is zero if [tex] x = -\frac{8}{3} [/tex]), so the ratio is less than or equal to zero.If [tex] x >4 [/tex] both numerator and denominator are positive, so the ratio is greater than or equal to zero.Answer:

Find S5 for a geometric series for which a1=81 and r=1/9.
ANSWER
[tex]S_5=91\frac{10}{81}[/tex]
EXPLANATION
The sum of the first [tex]n[/tex] terms of a geometric sequence is given by;
[tex]S_n=\frac{a_1(1-r^n)}{1-r} ,-1<\:r<\:1[/tex]
Where [tex]n[/tex], is the number of terms and [tex]a_1[/tex] is the first term.
When [tex]n=5[/tex], we have [tex]a_1=81[/tex], we get;
[tex]S_5=\frac{81(1-(\frac{1}{9})^5)}{1-\frac{1}{9}}[/tex]
[tex]S_5=\frac{81(1-\frac{1}{59049})}{1-\frac{1}{9}}[/tex]
[tex]S_5=\frac{81(\frac{59048}{59049})}{\frac{8}{9}}[/tex]
[tex]S_5=\frac{7381}{81}[/tex]
[tex]S_5=91\frac{10}{81}[/tex]

The values of x and y have been calculated as [tex]15[/tex] and [tex]12[/tex] respectively making option A the appropriate choice.
In the given question we can see that the angles [tex]62[/tex] degrees and [tex]4x + 2[/tex] degrees are alternate interior angles because they are alternately on the interior side of two parallel lines and transversal. hence, we can calculate x as:
[tex]62 = 4x + 2\\4x = 60\\x = 60/4 = 15[/tex]
Similarly, we can find the value of y as the angles [tex]12y[/tex] degrees and [tex]144[/tex] degrees are alternate interior angles.
[tex]12y = 144\\y = 144/12\\y = 12[/tex]
The values of x and y are [tex]15[/tex] and [tex]12[/tex] respectively.
Therefore, option A is the correct answer.

The height of a football during a punt is modeled by h=-16t^2+60t+3. If the football hits the ground, how long did it stay in the air?
"how long..." is asking for time (t). "The amount of time spent in the air" is the time from when the ball was kicked (0 seconds) to the time it landed on the ground. Need to find the x-intercepts (one will be negative which will be invalid). You can do this by factoring ... or by using the quadratic formula. With the equation you provided, it is not factorable, so you must use the quadratic formula.
h = -16t² + 60t + 3
a=-16 b=60 c=3
[tex]t = \frac{-b +/- \sqrt{b^{2}-4ac } }{2a}[/tex]
[tex]t = \frac{-60 +/- \sqrt{60^{2}-4(-16)(3) } }{2(-16)}[/tex]
[tex]t = \frac{-60 +/- \sqrt{3600 + 192} }{-32}[/tex]
[tex]t = \frac{-60 +/- \sqrt{3792} }{-32}[/tex]
[tex]t = \frac{-60 +/- 61.6}{-32}[/tex]
[tex]t = \frac{-60 + 61.6}{-32}[/tex] or [tex]t = \frac{-60 - 61.6}{-32}[/tex]
[tex]t = \frac{1.6}{-32}[/tex] or [tex]t = \frac{-121.6}{-32}[/tex]
t = -0.05 or t = 3.8 disregard the negative
