25.4 of 15% = ?????
HELP IM STUCK ON THIS QESTION!!!
Answers
Answer: 3.81
Step-by-step explanation:
Answer:
3.81
Step-by-step explanation:
1. We assume, that the number 25.4 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 25.4 is 100%, so we can write it down as 25.4=100%.
4. We know, that x is 15% of the output value, so we can write it down as x=15%.
5. Now we have two simple equations:
1) 25.4=100%
2) x=15%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
25.4/x=100%/15%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 15% of 25.4
25.4/x=100/15
(25.4/x)*x=(100/15)*x - we multiply both sides of the equation by x
25.4=6.66666666667*x - we divide both sides of the equation by (6.66666666667) to get x
25.4/6.66666666667=x
3.81=x
x=3.81

The following are the ages (years) of 5 people in a room:
17, 21, 15, 15, 25
A person enters the room.
The mean age of the 6 people is now 25.
What is the age of the person who entered the room?
Answers
Answer:
57 years
Step-by-step explanation:
The mean of a set of numbers is given as the ratio of the sum of the numbers to the number of numbers in the given data set.
Hence given that the age of 5 people are 17, 21, 15, 15, 25 and a 6th person joins the set, making the mean age 25, let the age of the new person that joined be x then
25 = (x + 17 + 21 + 15 + 15 + 25)/6
25 = (x + 93)/6
Multiply both sides by 6
150 = x + 93
subtract 93 from both sides
x = 150 - 93
x = 57 years
The age of the person who entered the room is 57 years
You are conducting an experiment to test the density of a new recipe for chocolate cake. You will test the recipe with 3 different baking temperatures (350, 400 and 450) and 3 different baking times (45 minutes, 55 minutes and 60 minutes).
How many treatments are there?
Answers
Answer: There are 9 possible treatments .
Step-by-step explanation:
There are 3 different baking temperatures (350, 400 and 450) and 3 different baking times (45 minutes, 55 minutes and 60 minutes).
By Fundamental counting principle,
Number of treatments = (Number of different baking temperatures) x (Number of different baking times)
= 3 x 3 = 9
Hence, there are 9 possible treatments .
The number of treatments is 9.
Given that,
You will test the recipe with 3 different baking temperatures (350, 400 and 450) and 3 different baking times (45 minutes, 55 minutes and 60 minutes).Based on the above information, the calculation is as follows:
Here we used the fundamental counting principle.
[tex]= 3 \times 3 \\\\= 9[/tex]
Therefore we can conclude that the number of treatments is 9.

A lorry travels 100 miles at an average speed of 25 mph.
Work out how long the journey lasts.
Answers
Answer:
Step-by-step explanation:
the journey will last
100 miles/25 mph=4 hours
Lorry travels 100 miles at a speed of 25 mph for 4 hours.
What is average speed?Average speed is calculated by dividing the entire distance that something has traveled by the overall amount of your time it took it to travel that distance. Speed is how briskly something goes at a specific moment. Average speed measures the typical rate of speed over the extent of a visit.
How to calculate time?We know that speed=distance/time
We have been provided that speed=25 miles per hour and distance is 100 miles. so so as to calculate the time we've got to merely put the values of speed and distance within the formula:
Time=distance/speed
=100/25
=4
Hence lorry will take 4 hours to hide 100 miles at a speed of 25 miles per hour.

Therefore, a triangle is possible with the given measurements,
Let us assume there is another triangle with same measurement with same measurements 7 cm, 6 cm, and 9 cm.,
By SSS congruency criteria both the triangles will be congruent.
Thus, all triangles with same measurement will be congruent to each other.

The range of f(x) = |x| is y ≥ 0. If a < 0 and b ≠ 0 for g(x) = a|x| + b, what is the range of function g?
Answers
The required range of the function g(x) = a|x| + b is y ≥ 0.
Let's analyze the function g(x) = a|x| + b step by step to determine its range.
The function |x| represents the absolute value of x, which means it always yields non-negative values. Therefore, a|x| will also be non-negative for any value of x.
Adding b to a non-negative value will shift the entire range up by b units, but it will still be non-negative.
Since a < 0, a|x| will be negative when x is positive. However, the absolute value function ensures that it will be positive when x is negative, balancing out the effect.
Finally, adding the constant term b to a|x| makes the entire range of g(x) non-negative.
In summary, the range of g(x) = a|x| + b is y ≥ 0.

Step-by-step explanation:
Answer:x=11 or x=-11
Step-by-step explanation: First, Use the FOIL method.
(x+5)(x+4)=9x+141
First: [tex]x^{2}[/tex]
Outer: 4x
Inner: 5x
Last: 5x4=20
Combine Like terms and write in standard form: [tex]x^{2}[/tex]+9x+20
Set up new equation:[tex]x^{2}[/tex]+9x+20=9x+141
Subtract 9x from both sides: [tex]x^{2}[/tex]+20=141
Subtact 20 from both sides: [tex]x^{2}[/tex]=121
Sqr root 121: [tex]\sqrt{121}[/tex] =11
Remeber a sqr root of a positive number can be positive and negative so x= 11 or -11
