Using proportions, it is found that the missile's internal computer clock is of 20 seconds.
According to the information given, this question can be solved by proportions, using a rule of three.50 tenths of a second is equivalent to 5 seconds, and we want to find the equivalent to 200 tenths of a second, thus, the rule of three is:
50 tenths - 5 seconds
200 tenths - x seconds
Applying cross multiplication:
[tex]50x = 5(200)[/tex]
[tex]50x = 1000[/tex]
[tex]x = \frac{1000}{50}[/tex]
[tex]x = 20[/tex]
The missile's internal computer clock is of 20 seconds.

Each face of a cube is a square with a side length of 3 meters. What is the total area of all the faces of the cube?
Answer: 54
Step-by-step explanation:
A cube is a perfect square to find the area use L x W and if the length is 3, the width is 9
A cube has 6 sides, so 9 x 6 = 54
The total area of all the faces of the cube is 54 square meters.
Let's dive into finding the total area of all the faces of a cube.
A cube is a special type of three-dimensional shape where all its sides (called faces) are equal squares.
In your case, each face has a side length of 3 meters.
Now, to find the total surface area of the cube, we need to calculate the area of each face and then add them up.
The formula to find the area of a square is side length squared, which is [tex]\(A = s^2\)[/tex], where [tex]\(A\)[/tex] is the area and [tex]\(s\)[/tex] is the side length.
So, for your cube, each face's area is [tex]\(3^2 = 9\)[/tex] square meters. Since a cube has 6 faces,
we simply multiply the area of one face by the number of faces: [tex]\(6 \times 9 = 54\)[/tex] square meters.
To sum it up, the total area of all the faces of the cube is 54 square meters.
This is calculated by finding the area of one face and then multiplying it by the total number of faces.
In this case, each face has an area of 9 square meters, and a cube has 6 faces, resulting in a total area of 54 square meters.

A snail travels 12 centimeters in 4 minutes. The snail travels the same distance each minute. How many milliliters did the snail travel each minute?
Answer:
the snail travels 30 mm per minute
Step-by-step explanation:
Well 12 cenitmters divided by 4 minutes equals the amount of centimeters the snail travels per minute, which is 3 centimeters (12 / 4 = 3). but be careful cuz we need to convert the 3 cm to mm. 1 cm = 10 mm so 3 cm = 30 mm.
the snail travels 30 mm per minute

Step-by-step explanation:
(x + 20)º and (4x - 5)º are supplementary angles, meaning the sum of their angles = 180º.
(x + 20) + (4x - 5) = 180
5x + 20 - 5 = 180
5x + 15 = 180
5x = 165
165/5 = 33

-When invested at an annual
interest rate of 7% an account
earned $581.00 of simple
interest in one year. How much
money was originally invested in
account
Answer:
$8300
Step-by-step explanation:
First, you need to know the formula for this type of question.
The formula is I = Prt. These variables are: I = Interest, P = Principle investment, r = Rate, and t = Time.
Your equation will be 581 = P(0.07)(1), since 0.07*1 is 0.07, you'll earn only 7% interest.
So, we broke down the equation to 581 = P(0.07), and you have to isolate P.
Since you have to isolate P, you divide 0.07 from both sides of the equation, which is 581/0.07 = 8300.
So, your principle investment is $8300.
Good luck!

For what values of x is f(x) =-2x - 3 increasing? For what
values of x is it decreasing?
Answer:
The value of y is decreasing for all real values of x (-∞,∞).
Step-by-step explanation:
Seeing as we have a simple 1st power equation, the slope will remain the same. So, we solve for slope to see if this equation is for an increasing or a decreasing line.
y = mx + b, where m = the slope of the line
Is the standard slope form of a line, which matches the one given.
so in our equation, f(x) = -2x -3, our m value is -2.
Seeing as -2 is less than 0, the answer is:
The value of y is decreasing for all real values of x (-∞,∞).
