hi samarelhedok

A rectangular prism is 2 inches by 4 inches by 6 inches.

Kimaya says, “It takes more 2/5-inch cubes to fill the prism than 1/5-inch cubes.”

Do you agree with Kimaya? Explain or show your reasoning.

Answers

No, I do not agree with Kimaya. The volume of the rectangular prism is 2 inches x 4 inches x 6 inches = 48 cubic inches. To fill the rectangular prism with 2/5-inch cubes, you would need 48 cubic inches / (2/5) cubic inches per cube = 120 cubes. To fill the rectangular prism with 1/5-inch cubes, you would need 48 cubic inches / (1/5) cubic inches per cube = 240 cubes.

So, it takes less 2/5-inch cubes to fill the prism than 1/5-inch cubes.

Another way to think of it is that the larger the cubes, the less number of cubes you need to fill the same volume, as the cubes are larger in size.

No, I do not agree with Kimaya, and heres why.

Simple Explanation: 2/5 in. cubes are more than 1/5 in. cubes, so 1/5 in. cubes would take 2x more to fill than 2/5 in.

Complex Explanation: 2 in. x 4 in. x 6 in. is 48 cubic in. and to fill 48 cubic in. using 2/5 in. per cube, it would be 120. as for 1/5 in., to fill 48 cubic in. with that would be 240. Easier way to think of it is that 2/5 in. cubes are already 120 and 1/5 would be doubling that so all you gotta do is multipy 120 x 2 since filling it with 1/5 would be 2x the amount than 2/5.

Answer:

B. 80 + 45 + 5x = 180

Step-by-step explanation:

In this problem, we are asked to construct an equation that can be used to solve for x.

The measures of the interior angles of a triangle add to 180º. Therefore, we can construct the following equation:

A + B + C = 180º

In this problem, we are given all of the shown triangle's angles: A = 80º, B = 45º, and C = 5xº. Thus, we can plug those values in for A, B, and C in the above equation.

80º + 45º + 5xº = 180º

This happens to be option B.

Answer: 80+45+5x=180

Step-by-step explanation: Angles in a triangle sum up to 180 degrees.

Nya wants to buy a sweater that had an orignial price of $55. The sweater is now discounted 20% and the sales tax rate is 5.5%. How much will Nya (Ichi Ni Sy Nya Arigatooo) pay for the sweater?

Answers

Answer:
=46.42
Step-by-step explanation:
First step is to find the discount
Discount = original price * discount rate
= 55 * 20%
= 55* 20
=11
Take the discount from the original price and that is the new price
new price = original price - discount
= 55-11
=44
Now we need to find the tax
tax = new price * tax rate
= 44 * 5.5%
= 44*.055
=2.42
The final price is the new price plus the tax
final price = new price + tax
= 44+2.42
=46.42

last summer at Gilliam Grant day camp the ratio of the number of counselors to the number of campers was 3 : 11. if there were a total of 168 people at the camp including counselors and campers how many counselors were there? how many campers were there?explain

Answers

Answer: the number of counselors is 312 = 36, and the number of campers is 1112 = 132

Step-by-step explanation:

To determine the number of counselors and campers at Gilliam Grant day camp, we can use the information provided in the ratio: 3 : 11.

This ratio tells us that for every 3 counselors, there are 11 campers. To find the total number of counselors and campers, we can set up the following equation using the information provided:

3x + 11x = 168 (x represents the number of counselors or campers)

14x = 168

x = 12

So the number of counselors is 312 = 36, and the number of campers is 1112 = 132

We can also check that the total number of counselors and campers is equal to 168 by adding 36 + 132 = 168

Answers

Answer: 1. Negative number

2. Natural number

3. Positive number

4. Integers

5. Number line

6. Opposite numbers

Step-by-step explanation:

1. The first statement says a number that is less than zero, which means any negative number would be less than zero. For example (-1), (-2), etc.

2. The second statement is asking for numbers belonging to the counting set, which means starting from one (1). Natural numbers are numbers that start from 1 and don't include negative numbers or zeros.

3. The third statement says the number that is greater than zero, as negative numbers are smaller than zero and the natural number option has already been chosen above, we will consider positive numbers.

4. Whole numbers consist of both negative and positive integers including zero. Therefore, a set of whole numbers will be written as integers.

5. Number line is a line that represents both negative and positive numbers.

6. Consider an example- (+5) and (-5), both the numbers are the same but with different signs, making them opposite of each other. Therefore, the correct answer would be opposite numbers.

How do I simplify Rational Exponents and Radicals?
I was absent yesterday and we completely moved onto a brand new subject. I don't quite understand, this isn't asking me to solve it, It's asking me to simplify it. help??

Some of the problems I don't understand:
4x⁻⁴y⁴
-2x⁴y⁻¹

Answers

Rational exponents and radicals are simplified in a similar way to how other exponents and radicals are simplified.

For the first expression 4x⁻⁴y⁴, you can simplify it by noticing that it has a negative exponent on the x term and a positive exponent on the y term. To simplify, you can keep the base (x and y) and the exponent (4 and -4) but you change the negative exponent to a fraction and change the sign:

4x⁻⁴y⁴ = (x^-4) (y^4) = x^-4y^4

For the second expression -2x⁴y⁻¹, you can simplify it by noticing that it has a negative exponent on the y term. To simplify, you can keep the base (x and y) and the exponent (4 and -1) but you change the negative exponent to a fraction and change the sign:

-2x⁴y⁻¹ = -2 (x^4) (y^-1) = -2x^4y^-1

To simplify these expressions further, you would need to know the specific values of x and y. But these are the steps to simplify a rational exponent or radical to its simplest form.

It's also worth mentioning that if you have a fractional exponent you can simplify it by raising the base to the numerator of the exponent and the denominator of the exponent. For example, x^(3/4) = (x^3)^(1/4) = ∛x

Keep in mind that when you simplify rational exponents or radicals, you should always keep the base and the exponent, and only change the sign of the exponent if it is negative.

Consider the standard form of an exponential function:

[tex]y=a(b)^x[/tex]
How does changing the base number (inside the parentheses) change your graph?

Answers

Answer:

Step-by-step explanation:

Challenge 1

We have exponential decline if 0 b 1. As you move from left to right, the curve will get less steep.

If b is greater than 1, exponential growth is present, and the curve slopes upward from left to right.

Examples include exponential decline (y = 2(0.5)x) and exponential growth (y = 2(1.2)x).

Remember that b cannot be negative.

===========================================

Challenge 2

In the general template provided, enter x = 0.

y = a(b)^x

y = a(b)^0

y = a(1) (1)

y = a

When x = 0 is plugged in, the result is y = a.

The curve is therefore on the point (0,a). The y intercept appears here. It is the point when the curve veers off the y axis. The y intercept is altered if the value of "a" is altered.
