Answer:
q = 4p - 32
Step-by-step explanation:
P = 1/4q + 8
Making q the subject
P - 8 = 1/4q
Divide both sides by 1/4
q = (p - 8) ÷ 1/4
= (P - 8) × 4/1
= 4p - 32
q = 4p - 32

Answer/Step-by-step explanation:
Given:
[tex] \frac{4}{x} - \frac{3}{y} = 1 [/tex] ---› Equation 1
[tex] \frac{8}{x} + \frac{9}{y} = 7 [/tex] ---› Equation 2
Solution:
✔️Equation 1 × 3:
[tex] \frac{4}{x}*3 + \frac{3}{y}*3 = 1*3 [/tex]
[tex] \frac{12}{x} + \frac{9}{y} = 3 [/tex] ---› Equation 3.
✔️Equation 2 + Equation 3:
[tex] \frac{8}{x} + \frac{9}{y} = 7 [/tex] ---› Equation 2
[tex] \frac{12}{x} + \frac{9}{y} = 3 [/tex] ---› Equation 3.
Thus:
[tex] \frac{-4}{x} = 10 [/tex]
Cross multiply
[tex] 10x = -4 [/tex]
Divide both sides by 10
[tex] x = -\frac{4}{10} [/tex]
[tex] x = -\frac{2}{5} [/tex]
✔️Find y:
Substitute x = -2/5 into equation 1
[tex] \frac{4}{x} - \frac{3}{y} = 1 [/tex] ---› Equation 1
[tex] \frac{4}{\frac{-2}{5}} - \frac{3}{y} = 1 [/tex]
[tex] \frac{4}*{\frac{5}{-2}} - \frac{3}{y} = 1 [/tex]
[tex] -10 - \frac{3}{y} = 1 [/tex]
Add 10 to both sides
[tex] - \frac{3}{y} = 1 + 10 [/tex]
[tex] \frac{-3}{y} = 11 [/tex]
Cross multiply
[tex] 11y = -3 [/tex]
Divide both sides by 11
[tex] y = -\frac{3}{11} [/tex]

A restaurant has a sign by the front door that says, "Maximum occupancy: 75 people."
What percentage of its capacity is 84 people?
Answer:
112%
Step-by-step explanation:
The percentage of its capacity is calculated as
Number of people / Maximum Occupancy × 100%
Number of people = 84 people
Maximum Occupancy = 75 people
Hence:
84 people /75 people × 100
= 1.12 × 100
= 112%
Therefore, the percentage of its capacity that is 84 people is 112 %

PLAYGROUND Lukas is walking around the edge of the playground shown. How far will Lukas have walked when he finishes one loop
around the playground? Round to the nearest unit, if necessary.
Answer:
40 units
Step-by-step explanation:
This question is essentially asking the perimeter of the traingle
We can easily find the sides AC and BA and while you can use the distance formula to find the last side this is a right triange so we will take an easier approach
So because AC has the same y we can very easily figure out how far apart they are by subtracting (or counting) the x values
For me I got AC= 15
AB is kind of the same deal but instead subtract the y value
I got BA= 8
We can now use the a^2+b^2=c^2 formula to get the length of the last side
8^2+15^2=c^2
This means that 289=c^2
take the square root of both sides to get
c=17
The final step is to get the perimeter which is 17+8+15 or 40

4x-10 and 58 are alternate interior angles since the lines are parallel
Alternate interior angles are equal.
4x-10 = 58
Add 10 to each side
4x-10 +10 = 58+10
4x = 68
Divide each side by 4
4x/4 = 68/4
x = 17
Answer:
17

The following are the ages (years) of 5 people in a room: 24, 17, 18, 16, 20 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?
Answer:
The man or woman that entered the room was 55 years of age.
Step-by-step explanation:
If we add up all the ages together, it is 95. When the other person walks in, the mean changes to 25. If you do the math, or if you count, the man or woman that enters is 55, which when added together, gives 150. divided by 6 equals 25.

Answer:
2 real solutions
Step-by-step explanation:
Remember this messy thing?
[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
The quadratic formula, as it's called, gives us the roots to any quadratic equation in standard form (ax² + bx + c = 0). The information on the type of roots is contained entirely in that bit under the square root symbol (b² - 4ac), called the discriminant. If it's non-negative, we'll have real roots, if it's negative, we'll have complex roots.
For our equation, we have a discrimant of (-3)² - 4(6)(-4) = 9 + 96 = 105, which is non-negative, so we'll have real solutions, and since quadratics are degree 2, we'll have exactly 2 real solutions.

An automobile manufacturer claims that its van has a 59.1 miles/gallon (MPG) rating. An independent testing firm has been contracted to test the MPG for this van since it is believed that the van has an incorrect manufacturer's MPG rating. After testing 160 vans, they found a mean MPG of 59.5. Assume the variance is known to be 2.89. A level of significance of 0.1 will be used. Find the value of the test statistic. Round your answer to 2 decimal places.
Answer:
Test statistic Z = 1.8099
Step-by-step explanation:
Step(i):-
Given that mean of the Population (μ) = 59.1 miles/gallon
Mean of the sample (x⁻ ) = 59.5
The standard deviation of the Population = 2.89
mean of the sample (n) = 160
Step(ii):-
Test statistic
[tex]Z = \frac{x^{-}-mean }{\frac{S.D}{\sqrt{n} } }[/tex]
[tex]Z = \frac{59.5-59.1 }{\frac{2.89}{\sqrt{160} } }[/tex]
Z = 1.8099
Test statistic = 1.8099
