Answer:

$5.27\times 10^{21}=5,270,000,000,000,000,000,000$

Step-by-step explanation:

Given : Number in scientific terms $5.27\times 10^{21}$

To find : What is number expressed in standard notation?

Solution :

The standard notation of a number is the expanded form of scientific notation.

The number we have given is $5.27\times 10^{21}$

Remove the decimal,

$\frac{527}{100}\times 10^{21}$

$527\times 10^{21-2}$

$527\times 10^{19}$

i.e. writing 19 zeros after the number,

$5270000000000000000000$

Therefore, The required number in standard notation is

$5.27\times 10^{21}=5,270,000,000,000,000,000,000$

Point B has coordinates (1,2). The x-coordinate of point A is -8. The distance between point A and point B is 15 units. What

Xelga [282]

Answer:

The possible coordinates of point A are $A_{1} (x,y) = (-8, 14)$ and $A_{2} (x,y) = (-8, -10)$ , respectively.

Step-by-step explanation:

From Analytical Geometry, we have the Equation of the Distance of a Line Segment between two points:

$l_{AB} = \sqrt{(x_{B}-x_{A})^{2} + (y_{B}-y_{A})^{2}}$ (1)

Where:

$l_{AB}$ - Length of the line segment AB.

$x_{A}, x_{B}$ - x-coordinates of points A and B.

$y_{A}, y_{B}$ - y-coordinates of points A and B.

If we know that $l_{AB} = 15$ , $x_{A} = -8$ , $x_{B} = 1$ and $y_{B} = 2$ , then the possible coordinates of point A is:

$\sqrt{(1+8)^{2}+(2-y_{A})^{2}} = 15$

$81 + (2-y_{A})^{2} = 225$

$(2-y_{A})^{2} = 144$

$2-y_{A} = \pm 12$

There are two possible solutions:

1) $2-y_{A} = -12$

$y_{A} = 14$

2) $2 - y_{A} = 12$

$y_{A} = -10$

The possible coordinates of point A are $A_{1} (x,y) = (-8, 14)$ and $A_{2} (x,y) = (-8, -10)$ , respectively.

White raven [17]

We have been given that Tim spends about 1/3 of each weekday sleeping and about 7/24 of each weekday in school. And we need to find what fraction of the weekday does Tim spend either sleeping or in school.

This means that we need to find the time he spends in sleeping when he is in the school.

Therefore, we have to add the time he spends in sleeping and the time he spends in school.

Therefore, required fraction is given by

$\frac{1}{3} +\frac{7}{24}$

Now in order to add the fractions, we have to make the denominator same.

Multiply the numerator and denominator of first fraction by 8 to make the same denominator.

$\frac{8}{24} +\frac{7}{24}$

Now, we have the same denominator hence, we can add the numerator

$\frac{8+7}{24}$

$\frac{15}{24}$

Therefore, Tim spends 15/24 hours each weekday sleeping in the school.
