Answer:

5000 meters

Step-by-step explanation:

kilometers to meters=1km to 1000m

so 5km to 5000m

The total meters did ed hike and swim on Saturday and Sunday 5000 meters.

We have given,

Ed hiked 3 kilometers on Saturday and

Swam 2 kilometers on Sunday.

Kilometers to meters

1km = 1000m

We have to find the total distance Ed hiked and swam on Sunday and Saturday,

Total distance=3km +2km

=3km +2km

=5km

1km=1000m.

So 5km to 5000m.

Answer:

  594 in²

Step-by-step explanation:

There are several ways to do this.

Given the way the figure is dimensioned, the last strategy is the easiest.

A rectangle that surrounds the entire figure will be 36 inches wide and 22 inches high. The white space rectangle in the lower right corner is shown to be 18 inches wide and 11 inches high.

The area of a rectangle is the product of its length and width:

  A = LW

So the difference in area between the "bounding" rectangle and the whitespace rectangle is ...

  shaded area = (36 in)(22 in) -(18 in)(11 in) = 792 in² -198 in²

  shaded area = 594 in²

_____

Additional comment

You can also recognize that the dimensions of the cut out corner are each half the overall dimensions. That means the shaded area is 3/4 of the overall "bounding" rectangle. There are several ways you can make use of that fact.

The value of E(Y) and Var(Y) are 50 and 178/5 respectively

Given the formula for temperature conversion expressed as:

Y = (9/5)*X + 32

where:

X stands for a temperature in degrees Celsius,

Y the same temperature in degrees

If E(X) = 10, then;

Y = (9/5) * 10 + 32

Y = (9*2) + 32

Y = 18 + 32

Y = 50

Hence E(Y) = 50

If Var(X) = 2

Y = (9/5) * 2 + 32

Y = 18/5 + 32

Y =  178/5

Hence Var(Y) = 50

The value of E(Y) and Var(Y) are 50 and 178/5 respectively

[tex]a_{n-2} = a_{n-3} + (n - 2) \implies a_n = a_{n-3} + n + (n - 1) + (n - 2)[/tex]

and the pattern continues down to the first term [tex]a_1=0[/tex],

[tex]a_n = a_{n - (n - 1)} + n + (n - 1) + (n - 2) + \cdots + (n - (n - 2))[/tex]

Answer:

Just add the 2 fractions that were mentioned

Step-by-step explanation:

turn 6 1/2 into an improper fraction and then add it to 5/8 by finding a common denominator

so it would be like -

13/2 + 5/8    =      52/8 + 5/8   =   57/8   =   7  1/8

Answer:

6 1/2 + 5/8 = 57/8 = 7 1/8 = 7.125

Step-by-step explanation:

Conversion a mixed number 6 1/2

to a improper fraction: 6 1/2 = 6 1/2 = 6 · 2 + 1/2 = 12 + 1/2 = 13/2

To find a new numerator:

a) Multiply the whole number 6 by the denominator 2. Whole number 6 equally 6 * 2/2 = 12/2

b) Add the answer from previous step 12 to the numerator 1. New numerator is 12 + 1 = 13

c) Write a previous answer (new numerator 13) over the denominator 2.

Six and one half is thirteen halfs

Add: 13/2 + 5/8 = 13 · 4/2 · 4 + 5/8 = 52/8 + 5/8 = 52 + 5/8= 57/8

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(2, 8) = 8. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 2 × 8 = 16. In the following intermediate step, it cannot further simplify the fraction result by canceling.

In other words - thirteen halves plus five-eighths = fifty-seven eighths.

Step-by-step explanation:

firstly working out without the power of 3

[tex]( \frac{10 {}^{15} }{10 {}^{5} } )[/tex]

this is the same as 10¹⁵ ÷ 10⁵

here the bases are the same and it's division so we subtract the powers

15 - 5 = 10

10¹⁵ ÷ 10⁵ = 10¹⁰

we are left with (10¹⁰)³, multiply the powers

10 × 3 = 30

final answer = 10³⁰

Hey there!

(10^15/10^5)^3

10^15

10^5

= 10 * 10 * 10 * 10 * 10

= 100 * 100 * 10

= 10,000 * 10

= 100,000

(1,000,000,000,000,000/100,000)^3

= (10,000,000,000)^3

= 10,000,000,000 * 10,000,000 * 10,000,000

= 100,000,000,000,000,000 * 10,000,000

= 10^30

Therefore, your answer is: 10^30

Step-by-step explanation:

a) It is an odd symmetry because it is symmetric about the origin, meaning if you rotate an odd function 180° around the origin, you will have the same function you started with.

b) It is an even symmetry because it reflects over the y-axis. The left and right looks the same.
