105 = 10 x 10 x 10 x 10 x 10 = 100,000 (5 zeros)
108 = 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 = 100,000,000 (8 zeros)
Notice that the number of zeros in the ordinary decimal expression is exactly equal to the power to which 10 is raised.
If the number is expressed in words, first write it down as an ordinary decimal number and then convert. Thus, "ten million" becomes 10,000,000. There are seven zeros, so in powers of ten notation ten million is written 107.
A number which is some power of 1/10 can also be expressed easily in scientific notation. By definition,
1/10 = 10-1 ("ten to the minus one power")
More generally, the expression "10-n" (where n is a whole number) means ( 1/10 )n. Thus
10-3 = ( 1 / 10 )3 = 1 / ( 10 x 10 x 10) = 1/1000
10-8 = ( 1 / 10 )8 = 1/100,000,000
The circumference of a circle is 48 pie units. What is the radius of the circle
Answer:
r = 24
Step-by-step explanation:
The formula for circumference is
C = 2*pi*r
48 pi = 2 * pi *r
Divide each side by 2pi
48 pi / 2pi = 2 * pi *r/ 2pi
24 = r
If x = a sec and y = b tan then find b^2x x^2-a^2x y^2
Describe what Pi is and explain how it is used in finding the circumference of a circle
Answer:
Sample response: Pi is a number that is approximated by 3.14, or 22/7. It is the ratio of the circumference to the diameter of any circle. This ratio can be rearranged to find circumference of a circle by multiplying pi times diameter.

A.
84 in2
B.
60 in2
C.
40 in2
D.
21.5 in
Answer:
Not on there but it is 76in2
Step-by-step explanation:
Starting with the trapezoid. We know that a trapezoid can be split into 2 triangles and 1 rectangle. So the area of the trapezoid will be 4+32+4 which is 40 now that we know the trapezoid's area we can find the rectangle's area. The rectangle's area will be 12x3 which is 36. So, you would add both:40+36= 76in2.

4) -8 – 3a = 46 whoever has best answer gets brainliest
Answer:
A= -18
Step-by-step explanation:
-8-3(-18)= 46= -18
Answer:
a=-18
Step-by-step explanation:
Let's break this down step by step.
-8-3a=46
Since 3a has a variable, a, we want to get it by itself. So the first step is to do the inverse operation and add 8 on both sides. That leaves this equation:
-3a=54
The 3a is -3a because of the subtraction sign in front. Now we divide on both sides because we want the variable, a, to be by itself. That leaves this simplified expression.
a=-18.
Now, let's work it out in context of the problem.
-8-3x-18=46
3x-18 is -54, and -8-(-54), it would become 46.

Joey's cleaning service charges $50 per week to clean a home. Amy's cleaning service charges $50 per week , plus $25 for cleaning supplies.
which equation can be used to express the amount that Amy's cleaning service charges?
A y=50x
B y=50x-25
C y=1/50x
D y=50x + 25
Answer:
D y=50x + 25
Step-by-step explanation:
The number of weeks can vary, so it is placed in front of a variable. The cleaning supplies cost does not, so it does not have a variable, but instead, it is a constant.
Answer:
D
Step-by-step explanation:
y = mx + b is the equation, where m = cost per week and b = cleaning supply cost (constant)
That means the equation is y = 50x + 25

Answer:
D. ( 3.6 , 2.2)
Step-by-step explanation:
Given
x + y = 5.8....equation 1
y = 2x - 5 ......equation 2
Putting equation 2 in equation 1
x + 2x - 5 = 5.8
3x = 5.8 + 5
3x = 10.8
Therefore x = 3.6
Now
y = 2 * 3.6 - 5
= 7.2 - 5
= 2.2

¿Cuál dígito debe ir en el recuadro para
que el siguiente número sea divisible
entre 2, 3 y 9? 8,? 48
Answer:
7
Step-by-step explanation:
English:
Which digit should go in the box to
make the next number divisible
between 2, 3 and 9? 8 ,? 48
Let x be the number, then the number will look like this:
8x48
This number is already divisible by 2, because it ends with an even number.
Now we need to check for divsibility by 3.
For this to be divisible by 3, the sum of the digit should be a multiple of 3.
[tex]8 + x + 4 + 8 = x +20[/tex]
We know if a number is divsible by 9, it is also divsible by 3.
So
[tex]x + 20=9,18,27,....[/tex]
The least positive solution is
[tex]x + 20 = 27[/tex]
[tex]x = 27 - 20[/tex]
[tex]x = 7[/tex]
Therefore 8748 is divsible by 2,3, and 9.

A boy owns 7 pairs of pants, 3 shirts, 2 ties, and 6 jackets. How many different outfits can he wear to school if he must wear one of each item?
He can wear different outfits.
Answer:
252 7 x 3 x 2
Step-by-step explanation:
The boy can wear 252 different outfits to school.
To calculate the number of different outfits, you can multiply the number of choices for each clothing item.
In this case, he has 7 choices of pants, 3 choices of shirts, 2 choices of ties, and 6 choices of jackets.
To find the total number of outfits, simply multiply these choices together: 7 pants x 3 shirts x 2 ties x 6 jackets = 252 different outfits.
This calculation works because for each choice of one item of clothing, there are still all the other choices available for the remaining items.
So, for every pair of pants, he can choose from 3 different shirts, and for each shirt-pants combination, there are 2 tie options, and so on.
Multiplying these choices together gives us the total number of outfits he can create while wearing one of each item.

the length of a rectangle is six times it’s width. If the perimeter of the rectangle is 112 yards, find it’s length and width.
The length of rectangle is 48 yards and width of the rectangle is 8 yards, if the perimeter of the rectangle is 112 yards.
Step-by-step explanation:
The given is,
The perimeter of the rectangle is 112 yards
The length of a rectangle is six times it's width
Step:1
Let, p - Perimeter of the rectangle
l - Length of the rectangle
w - Width of the rectangle
Step:2
Formula for perimeter of rectangle,
[tex]Perimeter, p = 2(l+w)[/tex]............................(1)
From given,
p = 112 yards
l = 6w ( ∵ From given)
w = w
Substitute the values,
112 = 2 ( 6w + w )
112 = 2 ( 7w )
112 = 14w
w = 8 yards
From the w value, l becomes
l = 6w
l = 6 × 8
l = 48 yards
Result:
The length of rectangle is 48 yards and width of the rectangle is 8 yards, if the perimeter of the rectangle is 112 yards.

What’s the value of x in degrees
Answer:
92⁰
Step-by-step explanation:
a = 35⁰ ( vertically opposite )
b = 53⁰ (vertically opposite )
a + b + x = 180⁰ (Angle sum property of triangle)
35⁰ + 53⁰ + x = 180⁰
x = 180⁰ - 88⁰
x = 92⁰

Which set of line segments could create a right triangle? (4 points)
O 15,30,35
O 15,36,39
O 15, 20, 29
O 5,15,30
Answer:
(B)15,36,39
Step-by-step explanation:
To determine which of the line segments could create a Right Triangle, we check if it satisfies the Pythagoras Theorem, taking the longest part to be the Hypotenuse in all cases.
By Pythagoras Theorem: [tex]Hypotenuse^2=Opposite^2+Adjacent^2[/tex]
In 15,30,35
[tex]35^2\neq 15^2+30^2\\1225\neq 1125[/tex]
In 15,36,39
[tex]39^2=36^2+15^2\\1521=1521[/tex]
In 15, 20, 29
[tex]29^2\neq 15^2+20^2\\841\neq 625[/tex]
In 5,15,30
[tex]30^2\neq 15^2+5^2\\900\neq 250[/tex]
We can see that only 15,36,39 satisfies the required condition and thus it could be used to create a right triangle.
Patrick has 2 black, 3 red, and 5 white toy cars. What is the ratio of red toy cars to all
the toy cars?
Answer:
3:10
Step-by-step explanation:
The question is asking the ratio of red cars to all the cars.
There are 3 red cars, and the total of the cars (all the cars) is 10.
The ratio is asking red to all.
So it is 3:10.
We want to get the ratio of red toy cars to the total number of red cars, we will get: 3:10
Here we know that:
There are 2 black cars, 3 red cars, and 5 white cars.
We want to get the ratio (remember that the ratio a to b is a:b) of red toy cars to all the toy cars.
First, we can see that there are 3 red toy cars.
And the total number of toy cars is:
2 + 3 + 5 = 10
So the ratio is just 3:10

How many integers are there in the solution set of the inequality |x−2000|+|x| ≤9999
Answer:
9999
Step-by-step explanation:
Find the greatest value of x and the least value of x that satisfy the equation:
2x-2000 = 9999 (Yields the greatest solution)
2x + 2000 = -9999 (Yields the least solution)
Solve both equations and you get:
3999.5 (Greatest solution)
-5999.5 (Least solution)
That means the range of integer solutions is between 3999 and -5999 (inclusive). That means there are 9999 integral solutions
Answer:
20,000 integers
Step-by-step explanation:
By triangular inequality,
|x - 2000 + x| ≤ |x−2000|+|x|
|x−2000|+|x| ≤ 9999
|x - 2000 + x| ≤ 9999
