Answer:
La masa de 10⁹ μm³ de agua es 1 mg.
Step-by-step explanation:
La densidad del agua es:
[tex] d = \frac{m}{V} = 1000 kg/m^{3} [/tex]
En donde:
m: es la masa =?
V: es el volumen = 10⁹ μm³
Para encontrar la masa de agua debemos convertir las unidades del volumen de μm³ a m³:
[tex]V = 10^{9} \mu m^{3}*\frac{1 m^{3}}{(10^{6} \mu m)^{3}} = 10^{-9} m^{3}[/tex]
Ahora, la masa es:
[tex]m = d*V = 1000 kg/m^{3}*10^{-9} m^{3} = 10^{-6} kg = 10^{-3} g = 1 mg[/tex]
Por lo tanto, la masa de 10⁹ μm³ de agua es 1 mg.

Answer:
Step-by-step explanation:
its about 263.08!
====================================================
Explanation:
We'll use this formula
S = (x/360)*A
where,
S = area of pie slice, aka sectorx = central angle in degreesA = area of full circleWe'll plug in S = 85.5 and x = 117 to find solve for A.
S = (x/360)*A
85.5 = (117/360)*A
85.5*(360/117) = A
A = 85.5*(360/117)
A = 263.076923076923 which is approximate
A = 263.08 square meters (choice C)
------------
Side note: As the formula suggests, the x/360 portion is the fractional portion of the full area A. For example, if x = 180 degrees, then x/360 = 180/360 = 1/2, meaning we'll take half of the full circle area to get S.

Answer:
x = 9
y = 3
z = 3
Step-by-step explanation:
Triangle 1 (From the left):
5x + 7x = 13x - 9 (Sum of two interior angles of a triangle is equals to exterior opposite angle)
Grouping like terms we have:
12x - 13x = - 9
x = 9
Triangle 2 (From the left):
30y = 90 (angles at a right angle = 90)
y = 3
Triangle 3 (From the left):
15z + 12z + 36 = 39z
36 = 39z - 27z
z = 36/12
z = 3

5=97 find 2 and 4....................,,..,...
Answer:
∠ 2 = ∠ 4 = 83°
Step-by-step explanation:
∠ 2 and ∠ 5 are same- side interior angles and sum to 180° , that is
∠ 2 + 97° = 180° ( subtract 97° from both sides )
∠ 2 = 83°
∠ 2 and ∠ 4 are vertical angles and are congruent, then
∠ 4 = 83°
3+2(15-11)
The first thing I did was
Change the (-) to a (+)
2) 2*15 = 30
3) change the 11 to -11
4) 2*11 = -22
5) 3+30+(-22) = ?
Step-by-step explanation:
3 + 2(15 - 11)
Step 1: use distributive property
2 x 15 = 30
2 x -11 = -22
3 + 30 + (-22)
3 + 30 - 22
Step 2: using PEDMAS, add the first two numbers
3 + 30 = 33
33 - 22
Step 3: subtract the last two numbers
33 - 22 = 11

York Canal
Distance = 5miles
Time = 15 minutes

Answer: I got this-- its me again.. It's D again- I explained this time tho-
Step-by-step explanation:
2 cm represents 100 miles, then 1 cm represents 50 miles and .5 cm represents 25 miles.
Town A = 175 miles from town B.
Town C = 100 miles from town B.
SO, Town A is 175 miles + 100 miles = 275 miles from town C.
How do you do that problem i am having trouble
Answer:
The answer is A
Step-by-step explanation:
We can tell by finding out what each points coordinates are.
Its quite hard to describe how to do this on a phond yet you use the rule of
X coordinate first, then Y coordinate.
so (-5,5). -5 is the x coordinate
and 5 is the y coordinate.
Graphs can be quite difficult but for now, just remember x is across and y is up.
Good luck with future questions!

the price of 1 toy car is $ 3, how much profit would a person have if he bought 4 of these cars and sold them for $ 5 in four?
♛♛♛♛♛♛♛♛♛♛♛♛♛♛♛
Answer:
Profit earn from selling all four cars = $8
Step-by-step explanation:
Given:
Purchase price of toy car = $3
Number of car purchases = 4
Selling price of each car = $5
Find:
Profit earn from selling all four cars
Computation:
Total amount of purchase = 3 x 4
Total amount of purchase = $12
Total amount of sales = 5 x 4
Total amount of sales = $20
Profit = sales cost - purchase cost
Profit earn from selling all four cars = 20 - 12
Profit earn from selling all four cars = $8
Answer:
$8

Use the given sequence to answer this following questions:
1, 6, 11, 16, 21, ...
1. Write a rule for the nth term of the arithmetic sequence. (Do not put any spaces between terms when writing the rule.)
2 find the tenth term.
Given:
The arithmetic sequence is:
[tex]1, 6, 11, 16, 21,...[/tex]
To find:
1. The rule for the nth term of the given arithmetic sequence.
2. The 10th term of the given arithmetic sequence.
Solution:
1. We have,
[tex]1, 6, 11, 16, 21,...[/tex]
Here, the first term is 1 and the common difference is:
[tex]d=a_2-a_1[/tex]
[tex]d=6-1[/tex]
[tex]d=5[/tex]
The nth term of an arithmetic sequence is:
[tex]a_n=a+(n-1)d[/tex]
Where, a is the first term and d is the common difference.
Putting [tex]a=1,\ d=5[/tex], we get
[tex]a_n=1+(n-1)5[/tex]
[tex]a_n=1+5n-5[/tex]
[tex]a_n=5n-4[/tex]
Therefore, the nth term of the given sequence is [tex]a_n=5n-4[/tex].
2. We need to find the 10th term of the given arithmetic sequence.
From part 1 it is clear that the nth term of the given arithmetic sequence is:
[tex]a_n=5n-4[/tex]
Putting [tex]n=10[/tex], we get
[tex]a_{10}=5(10)-4[/tex]
[tex]a_{10}=50-4[/tex]
[tex]a_{10}=46[/tex]
Therefore, the 10th term of the given arithmetic sequence is 46.
