Suppose that, in 1995, Germany produced 4.719 million computers. The total world production that year totaled 80 million computers. What percent of the world's total production of computers is contributed by Germany? Round your answer to the nearest tenth.
Answer:
To the nearest tenth
Percentage= 5.9%
Step-by-step explanation:
In 1995, Germany produced 4.719 million computers.
In that same year, the total computer production of the whole world was 80 million.
The percentage of the world production contributed by Germany
=Number produced by Germany/Number produced by the whole world * 100
The percentage of the world production contributed by Germany
=( 4.719/80)*100
The percentage of the world production contributed by Germany
=5.89875%
To the nearest tenth
= 5.9%

18.
16.
14.
12.
Answer:
14
Step-by-step explanation:
Perimeter of the ∆ = sum of the length of the 3 sides.
The length of the 3 sides can be calculated by using the distance formula, [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex], to find the distance between the vertices of the ∆.
The coordinates of the 3 vertices are:
(-1, 3), (2, 2), (-2, -2)
Distance between (-1, 3) and (2, 2):
Let,
[tex] (-1, 3) = (x_1, y_1) [/tex]
[tex] (2, 2) = (x_2, y_2) [/tex]
[tex] d = \sqrt{(2 -(-1))^2 + (2 - 3)^2} [/tex]
[tex] d = \sqrt{(3)^2 + (-1)^2} [/tex]
[tex] d = \sqrt{9 + 1} = \sqrt{10} = 3.2 units [/tex]
Distance between (2, 2) and (-2, -2)
Let,
[tex] (2, 2) = (x_1, y_1) [/tex]
[tex] (-2, -2) = (x_2, y_2) [/tex]
[tex] d = \sqrt{(-2 - 2)^2 + (-2 - 2)^2} [/tex]
[tex] d = \sqrt{(-4)^2 + (-4)^2} [/tex]
[tex] d = \sqrt{16 + 16} = \sqrt{32} = 5.7 units [/tex]
Distance between (-2, -2) and (-1, 3)
Let,
[tex] (-2, -2) = (x_1, y_1) [/tex]
[tex] (-1, 3) = (x_2, y_2) [/tex]
[tex] d = \sqrt{(-1 -(-2))^2 + (3 -(-2))^2} [/tex]
[tex] d = \sqrt{(1)^2 + (5)^2} [/tex]
[tex] d = \sqrt{1 + 25} = \sqrt{26} = 5.1 units [/tex]
Perimeter of triangle = 3.2 + 5.7 + 5.1 = 14.0 units

Answer:
The constant of proportionality is 1/3.
Step-by-step explanation:
You can find this answer by taking two coordinates shown and put them into a fraction form.
Example:
The second coordinate is (2, 6)--> 2/6, which reduced is 1/3.
To test that 1/3 is correct, you can do another coordinate: (4, 12)-->4/12, which reduced is also 1/3.
So 1/ 3 is correct.
Or take a look at the graph...
the red lines are always two units across, and the blue lines are always six units in height. So 2/6, (length, height), which can be reduced to 1/3, the constant of proportionality.
What is the solution of log(t-3) = log(17-4t)?
Answer:
t=4
Step-by-step explanation:
Answer:
Solution: 4
Step-by-step explanation:
We are given that log(t - 3) = log(17 - 4t), and need to solve for the value of t. Start off by applying the log rule 'If log(f(x)) = log(g(x)) say, then f(x) = g(x).' Similarly the equation boils down to the following:
t - 3 = 17 - 4t
Solving this equation, we will receive our solution. Let's do it:
t - 3 = 17 - 4t,
t = 20 - 4t,
5t = 20,
t = 20/5 = 4 ✓
The previous solution is correct.
y = 7x - 15
y = 4x - 12
Answer:
Step-by-step explanation:
7x - 15 = 4x - 12
3x - 15 = -12
3x = 3
x = 1
y = 7(1) - 15
y = 7 - 15
y = -8

A bag of peanuts weights 8 1/3 pounds. One serving
Is 1/3 pound. How many servings are in the bag?
Answer:
There are three servings in 1 pound so there are 8*3 servings in one pound which is 24. Plus an extra serving for the extra 1/3 pound makes for a final answer of 25 servings.

PLEASE HELP WITH PART 2! :)
Answer:
• The equation is a contradiction
• The solution set is Ø
Step-by-step explanation:
The simplest approach to this problem is solving for the value of y, and then identifying what type of equation it is. Remember that conditional equations have a defined value, contradiction equations have no solutions, and identity type equations have infinite solutions. Let's solve for y,
[tex]\mathrm{Given:5y\:+\:5\:-\:11y\:=\:-\:2y\:-\:7\:-\:4y},\\\\\mathrm{Add\:similar\:elements:}\\\\=> -6y+5=-2y-7-4y\\=> -6y+6y=-6y-12+6y\\=>0=-12[/tex]
Both sides are not equal, and hence we have no solutions. Our equation is contradiction, and the solution set is Ø.
Steps to solve:
~Combine like terms
-6y + 5 = -6y - 7
~Subtract 5 to both sides
-6y = -6y - 12
~Add 6 to both sides
0 = -12
There are no solutions.
Best of Luck!

Sketch and shade the region in the xy-plane defined by the equation or inequalities. |x| < 7 and |y| < 2
Answer:
Here we have:
IxI < 7
This also can be written as:
-7 < x < 7
and:
IyI < 2.
As above, we can write this as:
-2 < y < 2.
Then the graph of this region will be a rectangular area, where the perimeter is a dashed line (because here we use the strictly smaller or strictly larger symbols)
Such that the vertical component goes from -2 to 2, and the horizontal component goes from -7 to 7.
The area would be the area inside that rectangle, where i did not shade it so it is easier to read.
Mr. Edwards bought a 50-pound bag of flour for his bakery. It was equally divided among 6 days. How much flour was used per day?
Answer:
8 [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
50 ÷ 6 = 8.3333333333... Which simplify's (as a fraction) into 8 [tex]\frac{1}{3}[/tex].
Each day 8.33 pounds of flour is used.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Mr. Edwards bought a 50-pound bag of flour for his bakery.
It was equally divided among 6 days.
So, According per day the flour will be used
= 50/6
= 25/3
= 8.33 pound
Hence, 8.33 pounds used per day.

Answer:
Yes it's possible to make a triangle with 4, 4 and 16.
But if it also has 2 equal angles along with the equal sides (4 and 4), you can call it isosceles triangle.
One of the specialties at Dixie’s Cafe is vegetable stew, which simmers over a low flame all day. Since the cooking time is so long, Dixie must decide in the morning how many servings of the stew to cook for that night’s dinner service. Moreover, the stew cooked on a given day cannot be served the next day; it must be thrown away. Vegetable stew is the highest-profit item on the menu at Dixie's Cafe. It earns Dixie a profit of $8.

16. The price of an item will increase by RM4 every month. If the current price
is RM258, find its price in ten months' time.
Answer:
Sol:
The current price of item = RM258
The price that increases every month = RM4
Now,
It's price in ten month's line= Current price + 10 X increased price per month
= RM 258 + 10X RM4
=RM 258+ RM 40
= RM 298
Therefore, it's price in ten month's line will be RM 298
