Answer:
14 meters squared
Step-by-step explanation:
The dimensions of this rectangle are 4 1/5 meters by 10/3 meters. The area of a rectangle is: , where l is the length and w is the width.
Here, l = 4 1/5 and w = 10/3. We simply multiply them together:
A = (4 1/5) * (10/3)
Let's turn 4 1/5 into an improper fraction to make things easier: 4 1/5 = 21/5. Now:
A = (21/5) * (10/3) = 210/15 = 14
The area is 14 meters squared.
Hope this helps!
Answer:
14m²
Step-by-step explanation:
Area = length × width
length = 4⅕ = 21/5
width = 10/3
Area = 21/5 × 10/3
= 14m²

Final answer:
Lamar planted 4/15 of his land with corn. This was obtained by multiplying the fractions 2/3 and 2/5 to give the fraction of the land that was planted with corn.
Explanation:
To solve this problem, we need to find 2/3 of 2/5. Multiplication of fractions is the best method to use here. Multiply the numerators (top numbers) together and the denominators (bottom numbers) together.
Here are the steps:
- First, multiply the numerators: 2 * 2 = 4
- Then, multiply the denominators: 3 * 5 = 15
- So, 2/3 of 2/5 is equals to 4/15.
In conclusion, if Lamar planted 2/3 of his 2/5 land with corn, he planted 4/15 of the land with corn.

For every increase of 1 on the Richter scale, an earthquake is 10 times more powerful. Which of the following models this situation? answer-exponential growth function
b- linear function with a positive rate of change
c-exponential decay function
d-exponential growth function
Answers
The model that best describes this situation is an exponentialgrowthfunction.
The correct answer is option D.
What is a function?
A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
Exponential growth function
The given situation describes how the power of an earthquake increases exponentially with an increase in Richter scale magnitude.
Specifically, for every increase of 1 on the Richter scale, the earthquake is described as being 10 times more powerful.
This is characteristic of exponentialgrowth, where a quantity increases by a fixed proportion for each unit increase in another variable.
In this case,
As the Richter scale magnitude increases by 1, the power of the earthquake increases by a factor of 10, which is an exponentialgrowth relationship.
Therefore,
The model that best describes this situation is an exponentialgrowthfunction.

There are 8 bits in a dollar.
We have,
If a "bit" is defined as 1/8 of a dollar, we can calculate the number of bits in a dollar by dividing the dollar amount by the value of a bit.
1 dollar / (1/8) bit = 1 dollar * (8/1) bit
Simplifying the equation:
1 dollar * 8 bits = 8 bits
Therefore,
There are 8 bits in a dollar.

I somehow got -1(4/6)x=-5. Can someone provide a clear explanation on how to do this?
Answers
2 x + 3 y =105
x + 2 y = 6 /*(-2) // We will multiply 2nd equation by -2. That is because we want to cancel out the x`s//
2 x + 3 y = 105
-2 x - 4 y = -12 // Then we will add down these equations/ and x`s will cancel out//
3 y - 4 y = 105 - 12
- y = 93
y = -93
We can also solve x:
x + 2 * (-93)=6
x - 186 = 6
x = 6 + 186
x = 192
