Answer:
240 in^3
Step-by-step explanation:
1) remember that a laundry detergent box has a shape of a rectangle parallelepiped
2) find the volume with this formula:
V = base x width x height
V = 12 x 8 x 2.5 = 240 in^3
A construction worker drops a wrench from a height of 484 feel the function
h =
16x
+ 484 gives the height h of the wrench after a seconds When does the wrench hit the ground?
The wrench hits the ground blank
seconds after it is dropped
Answer:
30.25 seconds
Step-by-step explanation:
If you want to find the time at which the wrench hits the ground, you must recognize that the height of the wrench is 0 feet. If h represents the height, then 0 can be plugged in for h. The equation is now 0=16x+484. You then must subtract 484 from both sides, giving you -484=16x. You then divide both sides by 16 to give you x by itself. -484/16=-30.25. Because this is dealing with time and negative time does not exist, the negative sign on the 30.25 can be neglected.

22. Write a polynomial in simplest form
to express the shaded area in terms of .
9x2
7x
Answer:
The area of the shaded portion is;
A= π (81x^4 - 49x^2)
Step-by-step explanation:
Looking at the given figure, the area of the shaded part is simply the area of the bigger circle minus the area of the smaller circle
The bigger circle has a radius of 9x^2
The smaller circle has a radius of 7x
The radius is the distance from the center to any part of the circumference
The area of a circle can be calculated using the formula;
A = pi * r^2
For the bigger circle, we have;
A = pi * (9x^2)^2
A = pi * 81x^4
for the smaller circle, we have;
A = pi * (7x)^2
A = pi * 49x^2
So the area of the shaded portion will be;
A= π (81x^4 - 49x^2)

Tammy takes a marble out of a bag that contains 10 red marbles, 15 green marbles, and 25 blue marbles. She records its color and returns the marble to the bag. This would be a dependent event. True or False?
Answer:
true
Step-by-step explanation:
Answer:
The answer is yes.
Step-by-step explanation:
This is dependent because whichever color marble she picks out, is dependent on how many marbles of that color are in the bag. For example, since their are 25 blue marbles, there is a higher probability that she will pick a blue marble that any of the other colors.

what has two sides but can sometimes look like a line
Answer:
A string
Step-by-step explanation:
A plane will look like a line when viewed from a certain angle.
What is a plane?A plane is a two-dimensional, Euclidean, infinitely long surface in mathematics. A plane is a point's (zero dimensions), a line's (one dimension), and space's (three dimensions) two-dimensional equivalents.
A plane may appear as a subspace of a higher-dimensional space, such as the infinitely long wall of a room, or it may exist independently in its own right, such as in the context of two-dimensional Euclidean geometry. The terms hyperbolic plane and elliptic plane are two examples of two-dimensional surfaces that can sometimes be described more widely by the word plane.
A plane has two sides but when observed from a certain angle it can look like a line.

NO LINKS OR I WILL REPORT but helppp plsss A triangle has two sides of length 3 and 3. What value could the length of the
third side be? Check all that apply.
========================================================
Explanation:
We have a triangle with sides a,b,c where a = 3 and b = 3 are given. The side c is unknown, but using the variation of the triangle inequality theorem allows us to say the following:
b-a < c < b+a
3-3 < c < 3+3
0 < c < 6
The missing side c is between 0 and 6 units long, but cannot be equal to 0 and can't be equal to 6 either. Therefore, the answers must be A) 4, C) 5, and D) 2. All of these values satisfy the inequality 0 < c < 6.
Something like c = 12 is too large. I recommend cutting out two slips of paper that are 3 inches long, and you'll find it impossible to form a triangle that has a third side of 12 inches. The longest side you can form is 3+3 = 6 inches, but you wouldn't have a triangle at that point (it would be a straight line instead). This is a visual way to rule out choice E, and it also rules out choices B and F for similar reasoning.

4-13 writing exponential equations
Answer:
[tex]y=2(\frac{1}{3})^x[/tex]
Step-by-step explanation:
Let the equation of the given exponential function is,
y = a(b)ˣ
Graph of the given exponential function passes through (0, 2) and (-1, 6)
For a point (0, 2),
2 = a(b)⁰
a = 2
For another point (-1, 6),
6 = 2(b)⁻¹
3 = b⁻¹
b = [tex]\frac{1}{3}[/tex]
Therefore, equation of the exponential function will be,
[tex]y=2(\frac{1}{3})^x[/tex]
Magda and Nicholas each purchase almonds and cashews for their trail mix recipes as shown. What is the cost per pound of almonds and cashews?
Answer:almonds: 10.20
Cashews :12:40
Step-by-step explanation:
The cost per pound of almonds and cashews are 10.20 and 12:40, respectively
How to determune the unit costs of almonds and cashews?From the complete question, we have the following equations
6a + c = 73.6
4a + 3c = 78
Make c the subject in 6a + c = 73.6
c = 73.6 - 6a
Substitute c = 73.6 - 6a in 4a + 3c = 78
4a + 3(73.6 - 6a) = 78
Open the bracket
4a + 220.8 - 18a = 78
Evaluate the like terms
14a = 142.8
Divide by 14
a = 10.20
Substitute a = 10.20 in c = 73.6 - 6a
c = 73.6 - 6 * 10.2
Evaluate
c = 12.4
Hence, the cost per pound of almonds and cashews are 10.20 and 12:40, respectively

Looking at the diagram again, we see that the sides opposite both x and y are equal. And since they both share a line together, this means that two sides are equal in both triangles. Isosceles is the name of the triangle with two sides equal. Since both triangles have two sides equal, this means that x and y are the only sides that are not equal.
Again, looking at the diagram, we are given an angle to be 95°. Which means that, if the triangle of y has an angle of 95, then the corresponding angle in x will be less than 95. This fact also makes x as a side, to be less than y.

An empty bucket weighs 800g.
The weight of the bucket increases to 3.3kg when filled with water.
Calculate the percentage increase in the weight of the bucket.
Answer:
312.5%
Step-by-step explanation:
Convert 3.3kg to grams by multiplying by 1000
3.3×1000=3300g
%increase =Increase ÷Original ×100%
Increase=3300g -800g=2500g
2500÷800×100
=312.5%
The percentage increase in the weight of the bucket due to filling of water into it is 312.5.%
What is a percentage?
A percentage is a number or ratio that can be expressed as a fraction of 100. It can be calculated by using the formula:
Percentage=number*100/total number
How to calculate percentage?
We have been given that the weight of empty bucket is 800g and the weight of the bucket increases to 3.3 kg when filled with water.
We will first convert 3.3kg to g which will be 3300g
The percentage increase in the weight of the bucket
=(3300-800)*100/800
=250000/800
=2500/8
