Answer:
y - 6 = x/3 + 17/3 - 6
Step-by-step explanation:
x₁,y₁
A(-5,4)
x₂,y₂
B(1,6)
m = (y₂ - y₁) / (x₂ - x₁)
m = (6 - 4) / (1 - (-5))
m = 2 / (1 + 5)
m = 2/6
m = 1/3
y = mx + b B(1,6)
6 = (1) * 1/3 + b
6 = 1/3 + b
b = 6 - 1/3
b = (18 - 1) / 3
b = 17 / 3
y = x/3 + 17/3
y - 6 = x/3 + 17/3 - 6

Write an equation that Noah can use to find if he knows .
Answers
Answer: x = T - 4
T = y + 5
Step-by-step explanation:
a. To find the number of liters of soda water (x) if Noah knows the total number of liters (T) of sparkling orange juice he needs to prepare, the equation can be written as:
x = T - 4
b. To find the number of liters of sparkling orange juice (T) Noah can make if the school purchases a certain number of liters of orange juice (y), the equation can be written as:
T = y + 5
In both equations, x represents the number of liters of soda water, T represents the total number of liters of sparkling orange juice, and y represents the number of liters of orange juice.

Answer: 60 miles/hour
Step-by-step explanation:
Departure time: 5:30
Arrival time: 8:30
Distance = 180 miles
Total time it took to travel = 3 hours.
Recap: Distance = (Speed) × (Time)
Plug the number into the formula:
180miles = (speed) × 3hours
Solve for speed by dividing both sides by 3 hours:
180miles/3hours = Speed
Simplify:
60 miles/hour = Speed

The probability of sleet is given as 0.85. To express this probability as a fraction, we simply write the decimal as a fraction with a denominator of 1.
0.85 can be written as 85/100, which can be simplified by dividing both the numerator and denominator by 5 to obtain 17/20.
Therefore, the probability of sleet can be expressed as the fraction 17/20.
What is Probability?Probability is a measure of the likelihood of an event occurring and is expressed as a number between 0 and 1, inclusive. An event with a probability of 0 is impossible, while an event with a probability of 1 is certain.
Probabilities can be expressed as fractions, decimals, or percentages. To convert a decimal or a percentage to a fraction, we write the decimal or percentage as a fraction with a denominator of 1 and simplify the fraction if possible.
For example, if the probability of an event is given as 0.75, we can write this as 75/100. We can simplify this fraction by dividing both the numerator and denominator by 25 to obtain 3/4. Therefore, the probability of the event can be expressed as the fraction 3/4.
Similarly, if the probability of an event is given as 60%, we can write this as 60/100. We can simplify this fraction by dividing both the numerator and denominator by 20 to obtain 3/5. Therefore, the probability of the event can be expressed as the fraction 3/5.
Probabilities can be used to make predictions about the likelihood of future events, and they are an important tool in many fields, including statistics, science, and finance.

A triangular flag has a height of 15 inches and a base length of 25 inches. Magnolia makes a scale drawing of the flag in which the base length is 10 inches. What is the area of Magnolia’s scale drawing? Solve the problem by computing the actual area from the scale drawing. Show your work.
Answers
Answer:
The scale factor of the drawing is 10/25 = 2/5. This means that every length in the drawing is 2/5 of the actual length. Therefore, the height of the drawing is 2/5 * 15 = 6 inches.
To find the area of the drawing, we need to use the formula for the area of a triangle:
A = (1/2) * base * height
Plugging in the values, we get:
A = (1/2) * 10 * 6
A = 30
Therefore, the area of Magnolia's scale drawing is 30 square inches.
Step-by-step explanation:
To find the area of Magnolia's scale drawing, we need to compute the actual area based on the scale.
The scale ratio can be found by dividing the actual length by the corresponding length on the scale drawing. In this case, the base length on the scale drawing is 10 inches, while the actual base length is 25 inches.
Scale ratio = Actual length / Length on scale drawing
Scale ratio = 25 inches / 10 inches
Scale ratio = 2.5
Now, let's calculate the area of Magnolia's scale drawing using the scale ratio.
Area of scale drawing = (Length on scale drawing)^2 * Scale ratio
Since the scale drawing represents a triangular flag, we can use the formula for the area of a triangle:
Area of scale drawing = (0.5 * Length on scale drawing * Height on scale drawing) * Scale ratio
Plugging in the values, we get:
Area of scale drawing = (0.5 * 10 inches * 15 inches) * 2.5
Area of scale drawing = (0.5 * 150 inches^2) * 2.5
Area of scale drawing = 75 inches^2 * 2.5
Area of scale drawing = 187.5 inches^2
Therefore, the area of Magnolia's scale drawing is 187.5 square inches.

A coach calculated the mean and the mode of the number of points scored by 6 players.
• mean: 7 points
mode: 8 points
How many points did player 5 score?
Answers
Because 8+8+8+6+7+5=42
Then divide that by 6 to get the mean - so 42/6=7 so that’s the correct mean
Explanation:
Mean = average
Equation: total points scored/total players
Mean=7+8+6+8+?+8/6
The mean is given: 7
So plug it in:
7=(7+8+6+8+?+8)/6
Factor to solve:
Add all the numbers together to leave just the missing number (?)
7=(37+?)/6
To get rid of the 6 multiply it over to the other side
6x7=37+?
42=37+?
Now subtract the 37 to the other side to find the missing number (?)
42-37=?
5=?
Now let’s check:
7+8+6+8+(5)+8=42
Add:
42
Now divide by 6
42/6=
7
Is 7 the mean they gave us? Yup!
So player 5 scored 5 points

We know that the Angle Sum of a Triangle is equal to 180°.
So, Point A + Point B +Point C = 180°
= 1x° + 2x° + 3x° = 180°
