Time (days)

6
Cost (dollars)
6.00
8.25
10.50

Answers

Step-by-step explanation:

According to given table we have pairs of points:

(4, 6.00), (5, 8.25), (6, 10.50)

The rate of change is:

(8.25 - 6.00)/(5 - 4) = 2.25

(10.50 - 8.25)/(6 - 5) = 2.25

It is 2.25 and the meaning is:

Rental per day is $2.25

The average age of kishan and dolma is 15 years and that of dolma and shaswat is 14 years .If kishan is 17 years old ,find the age of dolma and shaswat.

Help me to find answer

Answers

Answer:

dolma is 13 and shaswat is 15

Step-by-step explanation:

lets say kishan is k, dolma is d, and shaswat is 14. (k+d)/2 is 15 so k+d=30. (d+s)/2=14 so d+s=28. since k=17, d=13 and s=15

IS CELL REPLICATION THE SAME THING AS DNA REPLICATION OR ARE THEY TWO SEPERATE THINGS

Answers

Answer:

See below:

Step-by-step explanation:

So, first of all, we know that Cell and DNA Replication are different just by looking at their names.

Cell Replication is to replicate cells and not DNA whereas DNA replication replicates DNA but not cells.

We do know that DNA resides inside Cells what we call eukaryotes.

So, in short, no, they are different things.

Cheers!

They’re connected but still different things. The cell cycle is the the process leading up to the cell actually dividing and the dna replication. So in the cell cycle, first you have the “resting phase” where the cell isn't dividing and is basically just kinda there. Then it goes into the interphase. First the cell grows (“Gap 1”) then synthesis happens which is where dna replication happens. Then the cell grows some more (“Gap 2”). Then the cell goes through mitosis which is where the cell stops growing and divides. Causing the cells to multiply. And DNA replication, which happens during synthesis. This is where a 2 pieces of identical dna are made from one dna molecule.

had to detour and went down 4 miles and the last day he went up 1 mile. How far
did he get up the mountain?

Answers

Answer:

14 miles if that's how far he went up

17miles if you're calculating his distance covered

The distance he hiked up the mountain is 10 miles.

What is an expression?

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that a mountain climber started at zero elevation. On the first day he hiked 10 miles up the mountain, on the second day it got steeper, and only hiked 3 miles, On the third day he had to detour and went down 4 miles, and on the last day, he went up 1 mile.

The total elevation will be calculated as below:-

Elevation = 10 + 3 + 1 - 4

Elevation = 14 - 4

Elevation = 10 Miles

Therefore, the distance he hiked up the mountain is 10 miles.

A pattern that increases or decreases at a constant rate is a linear function

Question 1 represents a linear functionQuestion 2 and 3 represent a nonlinear function

Question 1

From the table, we see that:

As x increases by 25, The value of y decreases by 1

The rate of increment/decrement is constant for both variables.

Hence, question 1 represents a linear function

Question 2

From the table, we see that:

As x increases by 2, The value of y increases at different rates

The rate of increment is not constant for variable y.

Hence, question 2 represents a nonlinear function

Question 2

From the table, we see that:

As the steps (i.e. x) increases by 1, The number of blocks (i.e. the value of y) increases at different rates

The rate of increment is not constant for variable y.

What's the best first step in solving-4 + 2/5 > 5/10

Answers

Answer:

Step-by-step explanation:

There are 2 operations happening on the left side to x.

1. x is being multiplied by -4.

2. 2/5 is being added to -4x.

If you had a number for x, and you wanted to evaluate the left side, first, you would multiply the value of x by -4. Then you would add 2/5.

To solve an equation or an inequality, you do the opposite operation in the opposite order.

Since the second operation was add 2/5, to solve, you start by doing the opposite of the second operation. That means you subtract 2/5 from both sides.
