Answer:
y = 32
Step-by-step explanation:
[tex]\frac{1}{2} y + 22 = 38[/tex]
Subtract 22 from both sides to isolate the y variable.
[tex]\frac{1}{2} y = 16[/tex]
Divide both sides by [tex]\frac{1}{2}[/tex], which is the same as multiplying by 2.
y = 32
1/2y + 22 = 38
-22 -22
1/2y = 16
x2 x2 ---> This is because if 1/2y = 26, that means y times 1/2 is 26, but we want to know what y times 1 is because y times 1 is equal to y so we multiply by 2 because 1/2 times 2 equals 1.
y = 32

A model of a lighthouse has diameter 8 inches and height 18 inches. If the
actual diameter of the lighthouse is 20 feet, find its actual height.
Answers
Answer:
45 feet.
Step-by-step explanation:
Given that a model of a lighthouse has diameter 8 inches and height 18 inches, and the actual diameter of the lighthouse is 20 feet, in order to find its actual height, the following calculation has to be made:
20 feet = 240 inches
240 / 8 = 30
Scale ratio: 1:30
18 x 30 = 540
540 inches = 45 feet
Therefore, the actual height of the lighthouse is 45 feet.

Step-by-step explanation:
Since the given triangles ΔLMN and ΔCBQ are similar,
Their corresponding sides will be proportional.

Answers
Answer:
b) μ = 2 and σ = 1.29
Step-by-step explanation:
Step(i):-
Given that the A spinner is divided into six equal-sized sectors labelled 1 through 6
Given that the probability of labelled '1'
[tex]p = \frac{1}{6}[/tex] =0.16
q = 1-p = 1- 0.16 = 0.84
Let 'X' be a random variable in binomial distribution
The mean of the binomial distribution
μ = n p
μ = [tex]12 (\frac{1}{6} ) = 2[/tex]
The mean of the binomial distribution = 2
Step(ii):-
The standard deviation of X
σ [tex]= \sqrt{npq}[/tex]
σ = [tex]\sqrt{12(0.16)(0.84}[/tex]
σ = [tex]1.269[/tex]
The standard deviation of the binomial distribution
σ = [tex]1.269[/tex]

y is inversely proportional to X.
When y
20, x = 2
Work out y when x = 5
Answers
Answer:
When x = 5, y = 8.
Step-by-step explanation:
y is inversely proportional to X.
This means that we solve this using the rule of three for inversely proportional variables, that is, we apply line multiplication instead of cross multiplication.
y = 20, x = 2
Work out y when x = 5
20 - 2
x - 5
Applying line multiplication
[tex]5y = 40[/tex]
[tex]y = \frac{40}{5}[/tex]
[tex]y = 8[/tex]
When x = 5, y = 8.

Answers
Answer:
East Port Tier City is 11.5 hours ahead of Phoenix.
Step-by-step explanation:
Given that the city of Phoenix, Arizona is located in the UTC -7 time zone, while East Port Tier City is located at UTC +4.5, to determine the time difference between the two cities, the following calculation must be performed:
4.5 - (-7) = X
4.5 + 7 = X
11.5 = X
Thus, the time difference between Phoenix and East Port Tier City is 11.5 hours.

what two letters don't appear on the telephone dial
Answers
Answer:
Step-by-step explanation:
Q and X
On a telephone dial, the letters "Q" and "Z" do not appear. The dial was designed to include commonly used letters and numbers, prioritizing efficiency and simplicity in dialing.
On a traditional telephone dial, there are two letters that do not appear:
The letter "Q" does not appear on the telephone dial. This omission is because the letter "Q" is not necessary for dialing phone numbers or for any commonly used telephone functions.
The letter "Z" is also absent from the telephone dial. This omission is because the letter "Z" is not needed for dialing phone numbers and is not commonly used in telephone-related applications.
The layout of the telephone dial was designed to accommodate the most frequently used letters and numbers while minimizing the number of keys. This design decision was made to ensure efficiency and simplicity in dialing numbers and accessing telephone services.

Please help me write the equation of a line that passes through the point ( -1, 5) and has a slope of -7
Answers
Answer:
y = -7x - 2
Step-by-step explanation:
use y = mx + b
y = y-coordinate = 5
m = slope = -7
x = x-coordinate = -1
b = y-intercept = the only missing piece/what we're solving
usually, for an equation, x and y stay as variables, but to find the y intercept we need to plug in the coordinates:
5 = (-7)(-1) + b multiply -7 and -1
5 = 7 + b subtract 7 from both sides
b = -2
plug b into the equation and leave x and y as variables:
y = -7x - 2
