When you write a number greater than or equal to 1 in scientific notation the exponent of the power of 10 will be?

Answers

Answer 1

When writing a number greater than or equal to 1 in scientific notation, the exponent of the power of 10 will be positive.

In scientific notation, a number is represented as a coefficient multiplied by a power of 10. For example, the number 12,000 can be written as 1.2 x 10⁴ in scientific notation.

When the number is greater than or equal to 1, the coefficient will be greater than or equal to 1 and less than 10. The exponent of the power of 10 will indicate the number of places the decimal point must be moved to the right to get the original number.

Since the number is greater than or equal to 1, the decimal point must be moved to the right, resulting in a positive exponent. So, when writing a number greater than or equal to 1 in scientific notation, the exponent of the power of 10 will always be positive.

Sam bought 6 pens for an unknown price plus a
backpack. If he spent a total of $28.50, write an
equation to find the cost of each pen.

Answers

so sam bought SIX pens for a TOTAL of $28.50. we have to figure out how much money each of the six pens cost.

steps:

1. divide the total by the amount of items purchased:

28.50 / 6 = 4.75

and there’s your answer! each pen cost $4.75

steps to check your work:

1. multiply the single cost by the amount of items purchased:

4.75 ( 6 ) = 28.50

Determine the intercepts of the line:

y = -9x - 14​

Answers

Answer: (-14/9, -14) or (-1.5, -14)

Step-by-step explanation:

y = -9x - 14

the coefficient without a variable in a slope-intercept equation is the y-intercept -- in this case, it is -14

to find the x intercept you use the equation given, set y to equal zero and Solve for x

- Your new equation should be: 0 = -9x - 14

Our new goal is to isolate the x

Start by doing the inverse of the coefficient, so add 14 to both sides

- Your new equation should be: 14 = -9x

Theres still a -9 attached to the x and the -9 is attached by multiplication -- so now you do the inverse function and divide both sides by -9

Your final answer: -14/9 = x or -1.5 with a repeating decimal

If a rectangle measures 21 centimeters by 28 centimeters what is the length in centimeters of the diagonal of the rectangle

Answers

Answer:

35cm

Step-by-step explanation:

Given data

Length= 21cm

Width= 28cm

Diagonal= ???

Applying Pythagoras theorem

D^2= L^2+W^2

D^2= 21^2+28^2

D^2= 441+784

D^2= 1225

D= √1225

D= 35cm

Hence the diagonal is 35cm

Solve this system of equations.Write your answer as an ordered pair.3x+4y=36 y=-1/2x+8

x = 4

y = 6

Step-by-step explanation:

[tex]\left \{ {{3x+4y=36} \atop {\frac{1}{2}x+4y=8 }} \right.[/tex] rewrite the equations and multiply bottom equations by -4

[tex]\left \{ {{3x+4y=36} \atop {-2x-4y=-32}} \right.[/tex] add both equations together

x = 4

then, input x=4 into equation 3x+4y=36:

3(4)+4y=36 (simplify)

12+4y=36 (subtract 12 from both sides)

4y=24 (divide both sides by 4)

Sum of the roots is:

1/2 + (-5) = - 4,5

Formation of quadratic equation:  

[tex]x^{2}[/tex] - (sum of the roots) x + product of the roots  =  0

[tex]x^{2}[/tex] - (-4,5) * x + (-2,5) = 0
