Answer:
In 2009 there would be 1,286,153,286 computers.
Step-by-step explanation:
Given that a computer industry expert reported that there were about 600 million computers in use worldwide in 2001 and that the number was increasing at an annual rate of about 10%, to determine how many computers would there have been worldwide in 2009, the following calculation must be done:
2002 = 600 x 1.1 = 660
2003 = 660 x 1.1 = 726
2004 = 726 x 1.1 = 798.6
2005 = 798.6 x 1.1 = 878.46
2006 = 878.46 x 1.1 = 966.306
2007 = 966.3 x 1.1 = 1,062.9366
2008 = 1,062.93 x 1.1 = 1,169.23026
2009 = 1,169.23026 x 1.1 = 1,286.153286
1,286.153286 x 1,000,000 = 1,286,153,286
Thus, in 2009 there would be 1,286,153,286 computers.

Answer:
Step-by-step explanation:
d is on a line with s so they are supplementary d+80 = 180 so d has to be 100
s and h are equal, therefore vertical angle x is also 80
Then 80 + 60 + y = 180 since they are on a straight line so y=40

The ratio of the weight of an object on Planet A to the weight of the same object on Planet B is 100 to 3. If an elephant weighs 5000 pounds on Planet A, find the elephant's weight on Planet B.
Answer:
one way to solve this question is to realize that every 100 pounds on planet A equals only 3 pounds on planet B.
So, 5000 pounds divided by 100 = 50. Then that number times 3 will give the weigh on planet B which is 150 pounds.
Algebraically, 100/3 = 5000/x; when we cross multiply, we get 15000/3 = x; x = 150

Answer:
5:4

Answer:
9 square units
Step-by-step explanation:
1.5+3+2+1+1.5=9
Which of the following is a solution of the system 2x + y = 9 and 3x + 5y = 19.
2x+y=9
3x+5y=19
I will do this problem in 2 ways. I.)Substitution II.)Elimination
Solution I.) Substitution
We can subtract 2x from both sides in the first equation.
y=9-2x
Now we can substitute the y in the second equation with 9-2x
3x+5(9-2x)=19
-7x+45=19
-7x=-26
x=26/7
y=9-2(26/7)=11/7
Solution II.)Elimination
We can multiply both side of first equation by 5 to get a 5y in both equations.
10x+5y=45
Now because both are positive 5y we just need to do simple subtraction of the 2 equation, each side respectively.
(10x+5y)-(3x+5y)=45-19
7x=26
x=26/7
2*26/7+y=9
y=11/7
Ultimately you get the same answer, both are viable methods, some problems are faster with one method but I recommend mastering both since they are very useful.
Kenya bought 4 boxes of
pencils for $3.99 each. She
also bought 2 boxes of
markers for $4.99 each. If
she paid the cashier with a
$50 bill, how much change
will Kenya get back?
Answer:
she will be recivining $24.06
Step-by-step explanation:
4x3.99=15.96
2x4.99=9.98
15.96+9.98=25.94
50-25.94=24.06

In the diagram below, OP is circumscribed about quadrilateral ABCD. What is
the value of x?
A. 52
B. 50
C.90
D. 92
The value of x is 50 because, in a quadrilateral, the sum of the opposite angles is equal to 180 degrees. option (B) is correct.
What is quadrilateral?
It is defined as the four-sided polygon in geometry having four edges and four corners and two pairs of congruent sides.
We have:
In the diagram below, OP is circumscribed about quadrilateral ABCD.
In a quadrilateral, the sum of the opposite angles is equal to 180 degree
x + 20 + 110 = 180
x + 130 = 180
x = 50
Thus, the value of x is 50 because, in a quadrilateral, the sum of the opposite angles is equal to 180 degrees. option (B) is correct.

Given the incomplete proof below, what is the missing reason for the statement in step 4?
Answer:
ASA Congruence Theorem
Step-by-step explanation:
Already,it has been stated and proved that two angles (<ABC and <CAB) and an included side (AB) in ∆ABC are congruent to corresponding two angles (<ABD and <DAB) and an included side (AB) in ∆ABD.
Therefore, based on the ASA Congruence Theorem, ∆ABC is congruent to ∆ABD.
The missing reason is "ASA Congruence Theorem"

Find tan 30°
Answer:
[tex]tan(30) = \frac{A}{B}[/tex]
Step-by-step explanation:
Given
The attached triangle
Required
Find tan(30)
Let the side opposite 30 degrees be A and the side adjacent 30 degrees be B
So [using tangent identity]:
[tex]tan(\theta) = \frac{Opposite}{Adjacent}[/tex]
This gives:
[tex]tan(30) = \frac{A}{B}[/tex]

What is the area of 19 centimeters?
Let's break this up:
Radius: 19
Diameter: 38
Circumference: 119.4
So...
The area of a circle with radius 19 is 1134
A = πr2 = π(d
2
)2 A = C2
4π
π = 3.1415
A = area
C = circumference or perimeter
r = radius, d = diameter
SOLUTION STEPS:
Area of a circle in terms of radius:
Area = π·r2 = 3.14·192 = 1134 square cm(*)
Area of a circle in terms of diameter:
Area = π·(d
2
)2 = 3.14·(38
2
)2 = 3.14·(19)2 = 1134 square cm(*)
Area of a circle in terms of circumference:
Area = C2
4π
= 119.42
4π
= 14256.36
(4·3.14)
= 14256.36
12.56
= 1134 square cm(*)
(*) 1134.1149479459 cm, exactly or limited to the precision of this calculator (13 decimal places).
Note: for simplicity, the operations above were rounded to 2 decimal places and π was rounded to 3.14.
Result in other units of area:
A circle of radius = 19 or diameter = 38 or circumference = 119.4 cm has an area of:
1.134 × 10-7 square kilometers (km²)
0.1134 square meters (m²)
1134 square centimeters (cm²)
1.134 × 105 square millimeters (mm²)

Find the area of a rectangle with base 2 yd and height 5 ft. (3 feet = 1 yard)
Answer:
30 sq ft
Step-by-step explanation:
2 yd = 6ft
6 x 5=30
P = ½ * a * h
a = 2 yd = 2 * 3 ft = 6 ft
h = 5 ft
P = ½ * 6 * 5 = 30 sq ft

6. What is the equation in slope-intercept form of the line that passes
through the points (-3,-1) and (2, 9)?
Answer:
y=2x+5
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(9-(-1))/(2-(-3))
m=(9+1)/(2+3)
m=10/5
m=2
y-y1=m(x-x1)
y-(-1)=2(x-(-3))
y+1=2(x+3)
y=2x+6-1
y=2x+5

11cm by 6 cm rectangle
Answer:
Question unclear.
If the question was about the perimeter of the rectangle, it is calculated as:
= (Length * 2) + (Height * 2)
= (11 * 2) + (6 * 2)
= 22 + 12
= 34 cm
If the question was bout Area, the area is:
= Length * width
= 11 * 6
= 66 cm²
