The required percentage is 12.5% of 1 hour which equals 7 minutes 30 seconds.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
To express 7 minutes 30 seconds as a percentage of 1 hour, you first need to convert the time to a common unit, such as seconds.
One hour is equal to 60 minutes, so 7 minutes 30 seconds is equal to 7 × 60 + 30 = 450 seconds.
Next, you need to express the time in terms of the total number of seconds in an hour.
One hour is equal to 60 minutes, and one minute is equal to 60 seconds, so one hour is equal to 60 × 60 = 3600 seconds.
To find the percentage of 1 hour that 7 minutes 30 seconds represents, you would divide the number of seconds by the total number of seconds in an hour, and then multiply the result by 100% to convert it to a percentage.
Using the values above, the calculation would be as follows:
450 seconds / 3600 seconds × 100% = 12.5%
Therefore, 7 minutes 30 seconds is equal to 12.5% of 1 hour.

B 12
C 17
D 18
Answers
Answer:
The value of the expression is 12 ⇒ B
Step-by-step explanation:
Let us solve the question
∵ The expression is 2n(n - 1)
→ Simplify it at first by multiply 2n by the bracket (n - 1)
∵ 2n(n - 1) = 2n(n) - 2n(1)
∴ 2n(n - 1) = 2n² - 2n
∵ n = 3
→ Substitute n by 3 in the expression to find its value
∴ 2n² - 2n = 2(3)² - 2(3)
∴ 2n² - 2n = 2(9) - 6
∴ 2n² - 2n = 18 - 6
∴ 2n² - 2n = 12 ⇒ at n = 3
∴ The value of the expression is 12

Find the angle of XYZ give your answer to 1 decimal place
Answers
Answer:
66.4°
Step-by-step explanation:
To find the angle XYZ, we are to use sine rule. For this, we have to first find ∠Z.
Given that: ∠X = 90° (right angle), XY = 6 cm, YZ = 15 cm. Hence:
[tex]\frac{sin(Z)}{XY}=\frac{sin(X)}{YZ}\\\\Substituting:\\\\\frac{sin(Z)}{6} =\frac{sin(90)}{15} \\\\sin(Z)=\frac{sin(90)*6}{15}\\\\sin(Z)=0.4\\\\Z=sin^{-1}(0.4)\\\\Z=23.6^o[/tex]
∠X + ∠Y + ∠Z = 180° (sum of angles in a triangle)
90 + ∠Y + 23.6 = 180
113.6 + ∠Y = 180
∠Y = 180 - 113.6
∠Y = 66.4°
∠Y = ∠XYZ = 66.4°

Step-by-step explanation:
The given equations are :
y = x + 3 .....(1)
y = 2x – 5 ......(2)
The table for equation (1) is :
x = 0, 1, 2, 8
y = 3, 4, 5, 11
The table for equation (2) is :
x = 0, 1 , 2, 8
y = -5, -3, -1, 11
From the graph we can see that,
The x-value is = 8
The y-value = 11
The solution is = (8,11).
The x-value is = 8, the y-value = 11 and the solution is = (8,11)
How to determine the equation solutions?The equations are given as:
y = x + 3
y = 2x - 5
Next, we plot the graph of the equations
From the graph of the equations, we have:
(x,y) = (8, 11)
Hence, the x-value is = 8 and the y-value = 11
So, the solution is = (8,11)

First add the numbers on the left side of the equation.
0.72 = 0.8 - 0.3x
Then move the variable to the left as well.
0.3x + 0.72 = 0.8
Move the constant to the right by subtracting.
0.3x = 0.8 - 0.72
Subtract the numbers
0.3x = 0.08
Divide both sides by 0.3.
And that should yield your answer.

A study about commuting time for workers in a certain city. The distribution is clustered on the left with most of the values less than about 40 minutes commute. There are a fairly large number of values that are much higher, even stretching out to 150 minutes. There is a 15% chance that a random worker has a commute time of greater than 45 minutes. If you were to sketch this distribution, what would it look like, how would you describe it, and how do you represent the 15% probability?
Answers
Answer:
Following are the solution to this question:
Step-by-step explanation:
Its laborer's journey through time was concentrated mostly on left as well as the amounts are mostly less than 4 min. There are quite a lot of significantly higher levels, even stretching to 150 min. A hypothetical worker is 15% likely to get a time difference longer than 45 min.
They learn from such data that perhaps the distribution of data takes a very long time. Thus the distribution will look like an's progressive. Its probability is positive. Therefore some severe finding beyond the regular standards is included. The mean of findings is also higher than the mean. Its problem would be that 15% of people are more likely to have been traveling more than 45 min in a specific worker. Subsequently, the 85th level of the data is 45 minutes, meaning whether 85% of observations are decreased or equivalent to 45 minutes or 15% more than 45 minutes.Number of digits in base 5 number system are

52+90+A=180

Step-by-step explanation:
the equation is -2x² = 4-3 (x + 1) and the question is justify that it is a 2nd degree equation with the unknown x complete.
Answers
Answer:
Please check the explanation.
Step-by-step explanation:
Given the equation
-2x² = 4-3 (x + 1)
-2x² = 4-3x-3
-2x² = -3x -7
0 = 2x² -3x -7
We know that the degree of the equation is the highest power of x variable in the given equation.
In the equation 0 = 2x² -3x -7 the highest power of x variable in the given equation is 2.
Thus, the degree of the equation is 2.
Also in the equation 0 = 2x² -3x -7, the unknown variable is 'x'.
Let us determine the value 'x'
2x² -3x -7 = 0
Add 7 to both sides
[tex]2x^2-3x-7+7=0+7[/tex]
[tex]2x^2-3x=7[/tex]
Divide both sides by 2
[tex]\frac{2x^2-3x}{2}=\frac{7}{2}[/tex]
[tex]x^2-\frac{3x}{2}=\frac{7}{2}[/tex]
Add (-3/4)² to both sides
[tex]x^2-\frac{3x}{2}+\left(-\frac{3}{4}\right)^2=\frac{7}{2}+\left(-\frac{3}{4}\right)^2[/tex]
[tex]x^2-\frac{3x}{2}+\left(-\frac{3}{4}\right)^2=\frac{65}{16}[/tex]
[tex]\left(x-\frac{3}{4}\right)^2=\frac{65}{16}[/tex]
[tex]\mathrm{For\:}f^2\left(x\right)=a\mathrm{\:the\:solutions\:are\:}f\left(x\right)=\sqrt{a},\:-\sqrt{a}[/tex]
solving
[tex]x-\frac{3}{4}=\sqrt{\frac{65}{16}}[/tex]
[tex]x-\frac{3}{4}=\frac{\sqrt{65}}{\sqrt{16}}[/tex]
[tex]x-\frac{3}{4}=\frac{\sqrt{65}}{4}[/tex]
Add 3/4 to both sides
[tex]x-\frac{3}{4}+\frac{3}{4}=\frac{\sqrt{65}}{4}+\frac{3}{4}[/tex]
[tex]x=\frac{\sqrt{65}+3}{4}[/tex]
similarly solving
[tex]x-\frac{3}{4}=-\sqrt{\frac{65}{16}}[/tex]
[tex]x=\frac{-\sqrt{65}+3}{4}[/tex]
So the solution of the equation will have the values of x such as:
[tex]x=\frac{\sqrt{65}+3}{4},\:x=\frac{-\sqrt{65}+3}{4}[/tex]
