Answer:
Option C is the correct answer.
Explanation:
Boxes collected by Mohammed = [tex]7\frac{1}{2}[/tex]
Boxes collected by Isaac = [tex]8\frac{1}{3}[/tex]
Boxes collected by Noah = [tex]4\frac{3}{4}[/tex]
Boxes collected by Felix = [tex]3\frac{2}{3}[/tex]
Total boxes collected = [tex]7\frac{1}{2}+8\frac{1}{3}+4\frac{3}{4}+3\frac{2}{3}[/tex]
= [tex]\frac{15}{2}+\frac{25}{3}+\frac{19}{4}+\frac{11}{3}=\frac{36}{3} +\frac{49}{4} =\frac{97}{4}[/tex]

Perform the indicated operation and then simplify 4m-3-9m+8
Final answer:
To simplify 4m - 3 - 9m + 8, combine like terms to get -5m + 5, which is the simplified expression.
Explanation:
To perform the indicated operation and simplify 4m - 3 - 9m + 8, we need to combine like terms. The terms 4m and -9m are like terms, as are the constants -3 and +8. So, let's combine them.
First, combine the m terms:
4m - 9m = -5m
Next, combine the constant terms:
-3 + 8 = 5
Putting it all together, we have:
-5m + 5
This is the simplified form of the original expression.

Factor.
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).
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.
I'd really appreciate if anyone helped! :)

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

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

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.
Writing a Polynomial Function Given a y-Intercept:
Suppose the graph of a cubic polynomial function has the same zeroes and passes through the coordinate (0, –5).
Describe the steps for writing the equation of this cubic polynomial function.
We are given
a cubic polynomial function has the same zeroes
Let's assume that zeros as 'a'
so, we can write it as
[tex]f(x)=(x-a)^3[/tex]
now, we are given y-intercept
(0,-5)
at x=0 , y=-5
we can use it and then find 'a'
[tex]-5=(0-a)^3[/tex]
[tex]a=\sqrt[3]{5}[/tex]
now, we can plug it
and we get
[tex]f(x)=(x-\sqrt[3]{5})^3[/tex]..................Answer
Answer:
Use the zeroes to determine the roots.
Write the polynomial as a product of the leading coefficient, a, and the factors, where each factor is x minus a root.
Use the y-intercept (0, –5) to solve for the leading coefficient.
Substitute the leading coefficient into the polynomial function for a and simplify.

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.

Select each correct answer.
(−3, 0)
(6, 1)
(1, −4)
(0, −3)
(2, −2)
To determine which ordered pairs are solutions to the inequality 2y - x ≤ -6, substitute the x and y values of each ordered pair into the inequality and check if it is satisfied.
Explanation:To determine which ordered pairs are solutions to the inequality 2y - x ≤ -6, we substitute the x and y values of each ordered pair into the inequality and check if the inequality is satisfied:
For the ordered pair (-3, 0): 2(0) - (-3) ≤ -6 → 0 + 3 ≤ -6 → 3 ≤ -6 (not satisfied)For the ordered pair (6, 1): 2(1) - 6 ≤ -6 → 2 - 6 ≤ -6 → -4 ≤ -6 (satisfied)For the ordered pair (1, -4): 2(-4) - 1 ≤ -6 → -8 - 1 ≤ -6 → -9 ≤ -6 (not satisfied)For the ordered pair (0, -3): 2(-3) - 0 ≤ -6 → -6 - 0 ≤ -6 → -6 ≤ -6 (satisfied)For the ordered pair (2, -2): 2(-2) - 2 ≤ -6 → -4 - 2 ≤ -6 → -6 ≤ -6 (satisfied)Therefore, the correct answers are (6, 1), (0, -3), and (2, -2).
