If a cube shaped cell is 3 units tall by 3 units wide and 3 units long, what is the volume of the cell?

Answers

it should be 6 because cubes have six sides

The volume of the cube is 27 cubic units.

Volume = side length × side length × side length

Given:

the side length of the cube is 3 units,

we can calculate the volume as follows:

Side length = 3 units

Volume = 3 units × 3 units × 3 units

              = 27 cubic units

So, the volume of the cube-shaped cell is 27 cubic units.

What equation could be used to solve this problem?

The sum of two consecutive integers is 141. Find the integers.

Answers

Thanks for your question!

The equation for two consecutive integers is:

x + (x+1) = y

Now, lets plug in the information we know:

x + (x+1) = 141

Even though the question asks for the equation, I'm going to solve anyway :)

2x + 1 = 141
2x = 140

In a recent year there were about 400,000,000 mobile internet users. That same year, there were about 1.2* into 10 ninths desktop internet users. About how many time larger was the number of desktop internet users than the number of mobile internet users?

Answers

Final answer:

The number of desktop internet users is 3 times larger than the number of mobile internet users.

Explanation:

To find out how many times larger the number of desktop internet users is compared to mobile internet users, we need to perform a division. We divide the number of desktop internet users by the number of mobile internet users.

The number of desktop internet users is represented as 1.2 x 109. To simplify this number, we can write it as 1,200,000,000. The number of mobile internet users is 400,000,000.

Now, we divide the number of desktop internet users by the number of mobile internet users:

1,200,000,000 / 400,000,000 = 3

Therefore, the number of desktop internet users is 3 times larger than the number of mobile internet users.

When 75% of a number is added to 6, the result is 3 more than the number. find the number?

Answers

hello : 
let : x  this the number
(75/100)x +6  = x+3

(3/4)x - x = 3 -6
(-1/4)x = -3
x = 12

To find the number in question, an equation is set up and solved, resulting in the number 12, which satisfies the given conditions where 75% of the number added to 6 equals 3 more than the number itself.

The question asks to find a number such that when 75% of it is added to 6, the result is 3 more than the number itself. To find this number, we can set up an equation: Let the number be represented by x. So, we have 0.75x + 6 = x + 3. To solve for x, we subtract 0.75x from both sides of the equation to get 6 = 0.25x + 3. Next, we subtract 3 from both sides to get 3 = 0.25x. Finally, dividing both sides by 0.25 gives us x = 12. Therefore, the number we are looking for is 12

Find an expression in simplest form for the verbal description. The sum of the cost of dinner d and a $27 tip divided equally between 3 people

Answers

Final answer:

The expression for the cost of dinner plus $27 tip divided by three people is (d + 27) / 3.

Explanation:

To find an expression for the given verbal description, first write the sum of the cost of dinner d and a $27 tip. This sum is represented by the expression d + 27. Then, to divide this sum equally among 3 people, you divide the entire expression by 3. The final expression in simplest form would be (d + 27) / 3.

Which statement is true about the domain of y = 3(2^-x)? Explain.

The domain is all real numbers greater than or equal to 2.
The domain is all real numbers greater than 0
The domain is all real numbers
The domain is all real numbers less than 0

Answers

We want to determine the domain of [tex]{y=3 \cdot 2^{-x}=3 \cdot ({2^{-1}})^x=3 \cdot ({ \frac{1}{2}})^x[/tex]

any function of the form [tex]y=f(x)=a \cdot b^x[/tex] is called an "exponential function",
the only condition is that b is positive and different from 1, and a is a nonzero real number.

The domain of such functions is all real numbers.

That is for any x, the expression 3(2^-x) "makes sense".



Answer: The domain is all real numbers

The correct statement about the domain of y = 3(2-x) is that the domain is all real numbers. The domain of the function y = 3(2^-x) is all real numbers, as there are no restrictions on x from the form of the function itself.

The correct statement about the domain of y = 3(2-x) is that the domain is all real numbers. This is because for the function given, there are no restrictions on the values that x can take. The base of the exponent, 2, is positive and since exponents can take any real number, negative or positive, there is nothing to prevent any real x from being used as an input. Furthermore, since the function does not contain any terms that would result in undefined operations, such as division by zero or negative numbers under an even root, the domain remains unrestricted.

Mike and his friend were playing 2 on 2 at the public court. They were using a homemade basketball and the volume of the ball was 288p. A regulation basketball has a circumference between 29.5-30 in. Can this ball be used in a regulation basketball game?

Answers

Volume = (4/3) pi r^3

288 pi = (4/3)pi r^3

r^3 = 288 / (4/3)  =  216

r  = 6 ins.

Circumference of the ball = 2 pi r  = 2*pi*6 =  37.70 in   so this ball cannot be used in  a regulation game of basketball.

After observing this pattern, Hideko made a conjecture for the next shape in the pattern. Five circles in a row. Each circle is divided into 4 equal-sized sectors. In the first circle, the top left sector is shaded. In the second circle, the bottom left sector is shaded. In the third circle, the bottom right sector is shaded. In the fourth circle, the top right sector is shaded. In the fifth circle, the top left sector is shaded. Which shape was most likely her conjecture for the next shape?

Answers

The left bottom sector will be the next shape that is going to be shaded.

Given that,
Five circles in a row. Each circle is divided into 4 equal-sized sectors.
In the first circle, the top left sector is shaded.

In the fourth circle, the top right sector is shaded.
In the fifth circle, t the bottom right sectoris shaded.
Which shape was most likely her conjecture for the next shape is to be determined.


What is the fraction?

Fraction is defined as the number of compositions that constitutes the Whole.

Here,
Let assign a number of shading to the various sector of the circle,
1 =  the top left sector
2 =  the bottom left sector
3 =  the bottom right sector
4 =  the bottom right sector

Now,
Series of shading the sector of a circle,
1, 2, 3, 4, 3, 2,1
We need to find what is the 6th conjecture
at 6th = 2
2 =  the bottom left sector

Thus, the left bottom sector will be the next shape that is going to be shaded.

This year your brother jack will be 2 years from being twice as old as your sister jen. the sum of jack’s age and three times jen’s age is 66. how old is jen?

Answers

Let the age of Jen 2 years later be x,

age of jack two years later = 2x
total age of jack and jen now = 2x + x - 2 - 2
= 3x - 4
3x - 4 = 66
3x = 70
x = 70/3
= 23.3 (to three significant figures)
age of jen now = x - 2
= 23.3 - 2
= 21.3

Jen is 21.3 years old now.

Daniel income tax rate is 15% if he made 32,000 this year what will his pay be in taxes this year

Answers

Final answer:

Daniel will pay $4,800 in taxes for the year by applying a 15% tax rate to his $32,000 income.

Explanation:

To calculate the amount of income tax Daniel will pay on his $32,000 income, we will apply the 15% tax rate that corresponds to the income bracket provided in the reference material. Here's how the calculation is done:

First, identify the total income: $32,000.Next, multiply the total income by the tax rate: $32,000 * 15% (or 0.15).The calculation will be: $32,000 * 0.15 = $4,800.

Therefore, Daniel will pay $4,800 in taxes for the year.
