What do you know about Scientific Notation

Answers

Answer 1

Answer:

Scientific notation is a way of expressing, and handling, a mathematical expression used to represent a decimal number between 1 and 10 (multiplied by ten), so large numbers can be made with using less digits. An example would be writing 4 x 10³ for 4,000.

9. The sum of two consecutive integers is 41 less than
four times the larger. Find the numbers.

Answers

Answer:

19 and 20

Step-by-step explanation:

Let x be the larger number

x - 1 + x = 4x - 41

We can combine like terms and isolate x:

2x - 1 = 4x - 41

2x = 40

x = 20

20 - 1 = 19

Solve for x. 5x+4=9

You have a wooden rod which is 24 1/2 inches long. Carlos needs a piece which is 8 3/4 inches long and Amanda needs a piece which is 6 3/8 inches long. How long will the rod be after you cut those pieces to give to Carlos and Amanda?

Answers

Answer:

8 3/4 inches

Step-by-step explanation:

Total length of the rod = 24 1/2 inches

Carlos = 8 3/4 inches

Amanda = 6 3/8 inches

length of the rod remaining = Total length - ( Carlos + Amanda)

= 24 1/2 - (8 3/4 + 6 3/8)

= 49/2 - (35/4 + 51/8)

= 49/2 - ( 75+51/8)

= 49/2 - 126/8

= 196-126/8

= 70/8

= 8 6/8 inches

= 8 3/4 inches

Length of rod remaining = 8 3/4 inches

Use the given conditions to write an equation for the line in​ point-slope form and general form. Passing through (-4,8) and parallel to the line whose equation is 3x-8y-7=0

Answers

Step-by-step explanation:

Hey there!

The equation of a st.line passing through point is;

(y - 8) = m1(x+4).........(i).

And another equation is;

3x - 8y - 7 =0.......(ii)

From equation (ii), we get;

[tex]slope(m2) = \frac{ - coeff. \: of \: x}{coeff. \: of \: y} [/tex]

[tex]m2 = \frac{ - 3}{ - 8} [/tex]

Therefore the slope is 3/8.

As they are parallel lines, their slopes are eaual.

i.e m1 = m2 = 3/8.

Putting value of slope (m1) in equation (i).

[tex](y - 8) = \frac{3}{8} (x + 4)[/tex]

Simplify them to get equation.

[tex]8(y - 8 ) = 3x + 12[/tex]

[tex]8y - 64 = 3x + 12[/tex]

[tex]3x - 8y + 12 + 64 = 0[/tex]

[tex]3x - 8y + 76 = 0[/tex]

Therefore therequired equation is 3x - 8y +76=0.

what is a perfect square trinomial and can you provide an example

Answers

An expressions obtained from the square of binomial expression is a perfect square trinomial . For example: x square+2x+1

A perfect square trinomial is a trinomial that factors as two identical binomials.

For example, x² + 8x + 16 factors as (x + 4)(x + 4) or (x + 4)².

Another example would be x² - 12x - 36 which factors as (x - 6)².

Point K on the number line shows Kelvin's score after the first round of a quiz: In round 2, he lost 9 points. Which expression shows how many total points he has at the end of round 2? 3 + (−6) = −9, because −9 is 6 units to the left of 3 3 + 6 = −9, because −9 is 6 units to the left of 3 3 + (−9) = −6, because −6 is 9 units to the left of 3 3 + 9 = −6, because −6 is 9 units to the left of 3

Answers

Complete question :

Point K on the number line shows Kelvin's score after the first round of a quiz: A number line is shown from negative 10 to 0 to positive 10. There are increments of 1 on either side of the number line. The even numbers are labeled on either side of the number line. Point K is shown on 3. In round 2, he lost 9 points. Which expression shows how many total points he has at the end of round 2? 3 + (−6) = −9, because −9 is 6 units to the left of 3 3 + 6 = −9, because −9 is 6 units to the left of 3 3 + (−9) = −6, because −6 is 9 units to the left of 3 3 + 9 = −6, because −6 is 9 units to the left of 3

Answer: 3 + (−9) = −6, because −6 is 9 units to the left of 3

Step-by-step explanation:

Given the following :

Width of number line = - 10 to + 10

Point K on the number line = +3 ( kelvin's score after the first round of quiz).

If Kelvin losses 9 points in round 2  = - 9

Hence at the end of round 2, He'll have a total of :

Point at the end of round 1 + point lost in round 2

3 + (-9) = - 6

-3 x -6 = 9
[tex] - 3 \times - 6[/tex]
3 × 6 = 9
negative times a negative equals a positive so it would be positive 9 not negative 9​

How do you divide decimals.

Answers

Answer:

we need to shift decimal then divide

Step-by-step explanation:

First we move the divisor (if its a decimal) to the right until there is no more dot. If your dividend is also a decimal you also need to move it to the right how many spaces you moved the divisor's.

Example:

923.56 ÷ 4.5

This means that we move the dot between 4 and 5 once. We do the same to 923.56.

This means our division problem will be

9235.6 ÷ 45.

Now just do the problem normally as you should.
