1.62 , 16.2% ,15/20
Answer:
1.62, 15/20, 16.2%
Step-by-step explanation:
Let us consider all the answers out of one. In percentages, 100% always equals 1. (If you ate 100% of a cookie, you would have eaten 1 cookie), 16.2% is much less than 100% and not even half of 100%.
16.2%<0.5
Following the same logic, imagine there are 20 cookies this time. 15/20 would be 15 out of the 20 cookies which is more than half.
15/20>0.5
Finally, 1.62 is greater than 1

For f(x) = -x-4 find the value of x for which f (x) = 1
Answer:
x = -5
Step-by-step explanation:
f(x) = -x-4
Let f(x) = 1
Find x
1 = -x-4
Add 4 to each side
1+4 = -x-4+4
5 = -x
Multiply each side by -1
-5 =x
x = -5
Answer:
x = -5
Step-by-step explanation:
Given that,
f ( x ) = - x - 4
If, f ( x ) = 1,
Let us find the value of x.
For that, replace f ( x ) with 1.
f ( x ) = - x - 4
1 = - x - 4
First, add x to both sides.
x + 1 = -4
Now, subtract 1 from both sides.
x = -4 - 1
x = -5

The average rate of speed in miles per hour is 15miles/hour.
What is the rate of speed ?
Acceleration, or the rate at which your speed is changing, is referred to as "rate of speed." Distances per time are used to measure "speed" (eg miles per hour). "Rate of speed" is expressed using units of distance per unit of time. Speed is determined by dividing the distance by the time.Calculating the units for speed requires knowledge of the units for both time and distance. Since the distance is measured in metres (m) and the time is measured in seconds, the units in this example will be metres per second (m/s) (s). Average speed combines the ideas of speed, which is a change in location, and average, which refers to a mean calculated from numerous data points, into a single phrase.Given that, a 4.5miles distance covered in 18 min and 7.5miles in 30 min
Converting miles/min to miles/hour and calculating the average,
Then
[(4.5 miles/18min )+(7.5miles/30min)]/2

liam descended from the summit of K2 to an elevation of 23,201.06 feet. what was the change in elevation.
Liam descended 5,050.25 feet. Elevation is defined as the distance above sea level. Elevations are typically expressed in meters or feet.
What is meant by elevation?The angle of elevation is formed by the intersection of the horizontal line and the line of sight. If the line of sight is directed upward from the horizontal line, the resulting angle is an angle of elevation. "rise over run" is an easy-to-remember equation for calculating change in elevation as a decimal, which means the rise (the change in vertical distance) divided by the run (the change in horizontal distance).
The angle of elevation is the angle formed by the horizontal line of sight and the upward line of sight. For example, if you're standing on the ground and looking up at the peak of a mountain, you can calculate the angle of elevation.
Therefore,
Liam descended from the summit of K2 (elevation= 28,251.31 feet) to an elevation of 23,201.06 feet.
You have to find the difference between 28,251.31 feet and 23,201.06 feet. To find the difference you have to subtract:
28251.31 - 23,201.06 = 5,050.25 feet
Hence, Liam descended 5,050.25 feet.

a fair die has four faces numbered one to four. what is the probability of rolling a two exactly three times in ten rolls of the die?
For a fair die has four faces numbered one to four, the probability of rolling a two exactly three times in ten rolls of the die is 25.02% determined using binomial distribution.
Binomial distribution is used to determine the probability of observing a specified number of successful outcomes in a specified number of trials and is given by:
P(x:n,p) = nCx px (1-p)n-x
Where n is the number of experiments, x is a random variable, and p is the probability of success in a single experiment.
The probability of rolling a two in one trail = ¼ = 0.25
In the give case,
n = 10
x =3
p = 0.25
Therefore,
P(3) = 10C3 0.25^3 (1-0.25)^(10 – 3)
Solving 10C3 = 10!/3!(10-3)! = 120
P(3) = 120. 0.25^3 (1-0.25)^(10 – 3) = 0.2502

what will the answer be
The value of the fraction expression 1/2 + 3/6 is 1.
The highest number that is a factor of all the numbers is known as the greatest common factor of two or more numbers.
The smallest number (non-zero) that is a multiple of all the numbers is known as the least common multiple of two or more numbers.
Consider the expression,
1/2 + 3/6 = x
Consider the fraction 3/6,
The factors of 3 are 1 and 3.
The factors of 6 are 1, 2, 3, and 6.
Therefore, the GCF or greatest common factor is 3.
Therefore,
3/6 = ( 3 ÷ 3 ) / ( 6 ÷ 3 ) = 1/2
So, the value of the expression will be:
x = 1/2 + 3/6
x = 1/2 + 1/2
As the denominators of the fractions are equal.
x = ( 1 + 1 )/ 2

Answer:
The rate in m³/m² is 40m³/m².
1 m³ is literally a cube with sides that are 1 m in length. 1 m = 100 cm, so each side of this cube is 100cm in length. Finding the volume means multiplying length by width by height:
100(100)(100)=1,000,000 cm³ in 1m³.
We know that we have 25,000cm³ of mulch; we divide to find how many cubic meters this is:
1,000,000/25,000 = 40 m³.
This makes the rate 40m³/m².

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
The total number of counters = 400
The number of counters that are red = 3/8 of total number of counters
= ( 3/8 ) x 400
= 3 x 50
= 150 counters
The number of counters that are yellow = 82 counters
So , the number of counters that are green =
Total number of counters - number of counters that are red - number of counters that are yellow
The number of counters that are green = 400 - 150 - 82
= 168 counters
Now , the percentage of counters that are green =
( number of counters that are green / total number of counters ) x 100
The percentage of counters that are green = ( 168 / 400 ) x 100
= 168 / 4
= 42 %
Hence , the number of counters that are green is 168 and the percentage of counters that are green is 42 %

Solve the system of equations by elimination.-2x + 2y + z = 143x - 2y + z = -5-x + y - 2z = -8c
x= -3, y = 1, z = 6
Explanation:
-2x + 2y + z = 14 ....equation 1
3x - 2y + z = -5 ....equation 2
-x + y - 2z = -8 ....equation 3
Note: Multiplication of same sign gives positive number. Multiplication of opposite signs give negative number.
Subtract equation 2 from 1:
-2x - 3x +2y -(-2y) + z - z = 14 -(-5)
-5x + 2y + 2y + 0 = 14 + 5
-5x + 4y = 19 ....equation 4
Due to the first equation we derived where we only have x and y. We need to solve the second equation in such a way we get only x and y.
This means we find a way to eliminate z in the second subtraction.
To do this, we multiply 1 by 2. Then we add both equations to eliminate z
-4x + 4y + 2z = 28 ....equation 1
-x + y - 2z = -8 ....equation 3
Add equation 3 and 1:
-4x + (-x) + 4y + y + 2z + (-2z) = -8 + 28
-4x - x + 5y + z + 2z - 2z = 20
-5x + 5y = 20 ....equation 5
-5x + 4y = 19 ....equation 4
-5x + 5y = 20 ....equation 5
subtract equation 4 from 5 (we will be eliminating x):
-5x -(-5x) + 5y - 4y = 20 - 19
-5x + 5x + y = 1
y = 1
we substitue the value of y in any of the equation between 4 and 5:
using equation 4:
-5x + 4(1) = 19
-5x + 4 = 19
-5x = 19-4
-5x = 15
x = 15/-5

7. The floor area of a passage is 2,4 m². The floor has to be tiled with square tiles of which the length of the sides is 200 mm. How many tiles do you need to cover the floor?
The number of tiles needed to cover the floor is 60 tiles.
Given Information,
The floor area of the passage = 2.4 m²
Length of a side of square tile = 200mm
Length of the side is in mm which needs to be converted in its standard form which is meters.

What is Algebraic expression ?
Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.
Here, it is given that :
Darren and his two siblings' ages are three consecutive odd numbers and the sum of their ages is 51.
Let Darren age be x
and since they are odd consecutive numbers, his two siblings age will be
1st sibling age will be = x+2
2rd sibling age will be = x+4
If the sum of their ages is 51
that is,
x+x+2+x+4= 51
solving for x:
3x+6 = 51
3x+6-6=51-6

Compound interest is used in savings accounts and CDs.First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
putting time into years for simplicity,
18 months ÷ 12 months/year = 1.5 years,
then, solving our equation
I = 4000 × 0.05 × 1.5 = 300
I = $300.00
