42 ounces
Step-by-step explanation:In this question, it is asking how many ounces of fiber did the Koala eat that day.
In order to solve this question, we would need to gather some important information from the question.
Important Information:
Koalas absorb only 25% of fiber they eatKoala absorbed 10.5 ounces of fiber in 1 dayWith the information above, we can solve the question.
We know that koalas only absorb 25% of fiber. We also know that a koala absorbed 10.5 ounces of fiber.
This means that the 10.5 ounces is 25% of fiber. This is 1/4 of the fiber it ate.
Now, we just need to find the other 3/4.
We could just multiply 10.5 by 4 to find how much fiber it ate that day.
[tex]10.5*4=42[/tex]
When you multiply, you should get 42.
This means that the Koala ate 42 ounces of fiber that day.
I hope this helps you out.Good luck on your academics.Have a fantastic day!Answer:
42
Step-by-step explanation:
We seek the answer to the question "10.5 ounces is 25% of what number?" If we call the unknown number of ounces x, we have the equation 10.5=0.25x. Dividing both sides by 0.25, we have x=10.5/0.25=42 ounces of fiber.

A man goes fishing in a river and wants to know how long it will take him to get 10km upstream
to his favourite fishing location. The speed of the current is 3 km/hr and it takes his boat twice
as long to go 3km upstream as is does to go 4km downstream. How long will it take his boat to
get to his fishing spot?
Answer:
Time = 25/9 hr
Step-by-step explanation:
Let speed of boat in still water is x km/hr
then, speed in downstream equals to "x + 3"km/hr
and speed in upstream equals to "x - 3" km/hr
We also know that time taken to travel 3km in upstream is twice as time taken to travel 4km in downstream.
so, using time = distance/speed
3/x- 3 = 2 × (4/x + 3)
3x + 9 = 8x -24
5x = 33
x = 33/5 km/hr
Net speed in upstream = 33/5 - 3 = 18/5 km/hr
So, Time taken to travel 10km upstream = distance /speed
= (10 × 5) / 18 = 25/9 hr
Time = 25/9 hr
The boat speed in still water is determined to be 6.6 km/hr, and it will take around 2.78 hours to travel 10 km upstream.
To determine how long it will take the man to travel 10 km upstream to his favorite fishing location, let's first define the boat speed in still water as v km/hr.
From the problem, we know:
The speed of the current is 3 km/hr.
It takes twice as long to travel 3 km upstream as it does to travel 4 km downstream.
The speed of the boat upstream relative to the shore is v - 3 km/hr, and downstream it is:
→ v + 3 km/hr.
Let t be the time it takes to travel 4 km downstream. Then time to travel 3 km upstream is 2t.
We can set up the following equations using distance = speed x time:
→ For downstream: 4 = (v + 3)t
→ For upstream: 3 = (v - 3)2t
Solve these equations:
→ From 4 = (v + 3)t, we have t = 4/(v + 3)
Substitute t in 3 = (v - 3)2t: 3 = (v - 3)2(4/(v + 3))
→ Simplify: 3(v + 3) = 8(v - 3)
→ Expand and solve for v: 3v + 9 = 8v - 24
→ 33 = 5v
→ v = 33/5
= 6.6 km/hr
Now that we know the speed of the boat in still water is 6.6 km/hr, we can determine the time it takes to travel 10 km upstream:
→ The effective speed upstream is:
= 6.6 - 3
= 3.6 km/hr.
→ Time required to travel 10 km upstream is:
= 10 / 3.6
≈ 2.78 hours.

Eighty percent of the students in a class (group A) share 40% of the candy equally. The remaining 20% of the students (group B) share the other 60% of the candy equally. The ratio of the amount of candy a student in group A has to the amount of candy a student in group B has is equal to what common fraction?
Answer:
1/6
Step-by-step explanation:
There is x candy in total and y students in total.
Group A consists of 0.8y students, and group B consists of 0.2y students.
Group A gets 40% of x, or 0.4x. Each student in group A gets 0.4x/(0.8y) = 0.5x/y candy per person.
Group B gets 60% of x, or 0.6x. Each student in group B gets 0.6x/(0.2y) = 3x/y candy per person.
The ratio of candy each student in group A has to the amount of candy each student in group B has is:
(0.5x/y)/(3x/y) = 0.5/3 = 1/6
The ratio of the amount of candy a student in group A has to the amount of candy a student in group B has is equal to 1/6
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that Eighty percent of the students in a class (group A) share 40% of the candy equally.
The remaining 20% of the students (group B) share the other 60% of the candy equally.
We need to find the common fraction between Group A and group B if ratio of the amount of candy a student in group A has to the amount of candy a student in group B has is equal
Let the total number of candy's are x
The total number of students are y.
The number of students in group A=0.8y
The number of students in group B=0.2y
Group A gets 40% of x, or 0.4x.
Each student in group A gets 0.4x/(0.8y) = 0.5x/y candy per person.
Group B gets 60% of x, or 0.6x. Each student in group B gets 0.6x/(0.2y) = 3x/y candy per person.
The ratio of candy each student in group A has to the amount of candy each student in group B has is:
(0.5x/y)/(3x/y) = 0.5/3 = 1/6
Hence, the ratio of the amount of candy a student in group A has to the amount of candy a student in group B has is equal to 1/6

Which of the following options is a polynomial with a root 2i and exactly 2
real roots?
Answer:
B. [tex]f(x)=x^4-x^3+2x^2-4x-8[/tex]
Step-by-step explanation:
If [tex]2i[/tex] is a root of f(x), then the complex conjugate [tex]-2i[/tex] is also a solution. If f(x) should have exactly 2 real roots, then by the Fundamental Theorem of Algebra, the minimum degree of f(x) is 4.
Hence the first and last options are eliminated.
By the Remainder Theorem, [tex]f(2i)=0[/tex].
Let us check for options B and C.
For option B.
[tex]f(x)=x^4-x^3+2x^2-4x-8[/tex]
[tex]\implies f(2i)=(2i)^4-(2i)^3+2(2i)^2-4(2i)-8[/tex]
[tex]\implies f(2i)=16i^4-8i^3+8i^2-8i-8[/tex]
[tex]\implies f(2i)=16+8i-8-8i-8=0[/tex]
For option C
[tex]f(x)=x^4-x^3-6x^2+4x+8[/tex]
[tex]\implies f(2i)=(2i)^4-(2i)^3-6(2i)^2+4(2i)+8[/tex]
[tex]\implies f(2i)=16i^4-8i^3-24i^2+8i+8[/tex]
[tex]\implies f(2i)=-16+8i+24+8i+8\ne0[/tex]
Therefore the correct choice is B.

Select the values that are solutions to the inequality x2 + 3x – 4 > 0.
The solutions to the inequality x^2 + 3x - 4 > 0 are all real numbers where x is less than -4 or greater than 1, represented by the intervals (x < -4) or (x > 1).
To find the values that are solutions to the inequality x2 + 3x - 4 > 0, we first need to determine the roots of the quadratic equation x2 + 3x - 4 = 0. We can do this either by factoring, completing the square, or using the quadratic formula. In this case, factoring is the simplest approach:
x2 + 4x - x - 4 = 0
(x + 4)(x - 1) = 0
Therefore, the roots are x = -4 and x = 1. Since it is a parabola opening upwards (the coefficient of x2 being positive), the inequality x2 + 3x - 4 > 0 holds true when x is either less than -4 or greater than 1.
The solution set is thus all real numbers outside the interval [-4, 1], which can be written as (x < -4) or (x > 1).

Answer:
C = pi * d formula
C = 314 ft
Step-by-step explanation:
To find the distance around the theatre, we want to use circumference.
C= 2 * pi *r where r is the radius
or

Answer:
D one diagonal bisects opposite angles and the other diagonal does not
Option D, 'one diagonal bisects opposite angles and the other diagonal does not,' does NOT guarantee that a quadrilateral is a kite.
To determine if a quadrilateral is a kite or not based on its properties.
A quadrilateral is a kite if and only if its diagonals are perpendicular and exactly one of them bisects the other diagonal. Let's analyze the given options:
If a quadrilateral has two distinct pairs of congruent adjacent sides, it is not necessarily a kite.If a quadrilateral has perpendicular diagonals, it is one condition for it to be a kite, so this option could guarantee a kite.If a quadrilateral has perpendicular diagonals, exactly one of which bisects the other, it guarantees a kite.If one diagonal bisects opposite angles and the other diagonal does not, it is not sufficient to guarantee a kite.Therefore, option D, 'one diagonal bisects opposite angles and the other diagonal does not,' does NOT guarantee that a quadrilateral is a kite.

What is 12% of 4? Explain and Show your work
Answer:
0.48
Step-by-step explanation:
convert the percent to a decimal
12%=0.12
multiply 4 by 0.12
you're left with 0.48
you can check your math by dividing .48/.12, which will give you 4
To solve this you must use a proportion like so...
[tex]\frac{part}{whole} = \frac{part}{whole}[/tex]
12 is a percent and percent's are always taken out of the 100. This means that one proportion will have 12 as the part and 100 as the whole
We want to know what is 12% of the number 4. This means 4 is the whole and the unknown (let's make this x) is the part.
[tex]\frac{x}{4} =\frac{12}{100}[/tex]
Now you must cross multiply
x*100 = 4*12
100x = 48
Now isolate x divide 100 to both sides
100x/100 = 48/100
0.48 = x
This means that 12% of 4is 0.48
