What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division. The Numbers constants, variables, operations, brackets can all be represented by mathematical symbol; which can also be used to indicate the logical syntax's order of operations and other features.

Therefore, each number as a single digit times a power of ten.

1. 0.000000043 is [tex]4 \times 10^{-9}[/tex]

2. 43560000.000 is[tex]4 \times 10^{10}[/tex]

3. 56.234567 is [tex]5 \times 10^7[/tex]

4. 0.00002346 is [tex]2 \times 10^{-5}[/tex]

Hence, The numbers as a single digit times a power of ten are ; 1. 4x10^-9, 2. 4x10^10, 3. 5x10^7, 4. 2x10^-5

The mean marks of 100 students were calculated as 65. At the time of checking it was found the marks 40 and 50 was wrongly copied and weeded out Find the correct mean marks.

Answers

Answer:

[ Because those two numbers are removed you need to reduce the number of terms to 98. ]

☆Solution☆

N=100

Mean=65

(Wrong Numbers=40,50)

Now,

Mean=Sum/No. of items

or,65=Sum/100

▪Sum=65×100=6500

After removing the unnecessary numbers,

New Sum=6500-40-50=6410

New no.of terms(N)=100-2=98

Now,

New Mean=New Sum/New N

=6410/98

Find the measure of the indicated arc in circle O. Use pic for more

Answers

Note that m∡DC = 44°.

How did we arrive at this ?

Note that the measure of the central angle and the arc it creates are the same.

Thus, since ∠DOC creates ∡DC

Hence, ∡DC = 44°

Note that an inscribed angle in geometry is the angle created in the inside of a circle when two chords meet on the circle.

It may alternatively be defined as the angle formed by two given points on a circle at a specified position on the circle. one inscribed angle is formed by two circle chords that share one endpoint.

Another company charges $8 per month and $0.03 per minute used. Which equation below best respresents the total cost for the month, c, for m miuntes used?

Answers

Answer: c = 8 + 0.03m

Step-by-step explanation:

From the question, we are informed that a company charges $8 per month and $0.03 per minute used.

The equation that best respresents the total cost for the month, c, for m miuntes used will be:

c = 8 + (0.03 × m)

c = 8 + (0.03m)

c = 8 + 0.03m

For example if 10 minutes was used, the cost will be:

c = 8 + 0.03m

c = 8 + (0.03 × 10)

c = 8 + 0.3

c = $8.3

Explanation:

Replace the variable x with 3 in the expression.
