The answer is the ratio of A's to the number of classes is 7 to 4. That's false. For the statement to be true the ratio should have been 4 to 7.
Step-by-step explanation:
To find perimeter, you need to add all the sides of the shape.
The area of a traingle is 1/2 bh.
You must find the "b" in order to find the perimeter.
Example:
A triangle has an area of 18 cm^2.
Therefore, the triangle has a 6 cm base and 6 cm height.
Then multiply the base by three to get 18 cm. That is your perimeter.
X = time, minutes
y = length, inches
When x = 32 min, y = 11.2 in
When x = 32+18 = 50, y = 10.75 in
Assume that a linear relatioship exists between x and y.
In table form, the given data is
x, min: 32 50
y, in: 11.2 10.75
The slope is
m = (10.75 - 11.2)/(50 - 32) = -0.025
In point-slope form, the required equation is
When x = 3 hours = 180 minutes, obtain
y - 10.75 = -0.025*(180 - 50) = -3.25
y = -3.25 + 10.75 = 7.5 in
Answer: 7.5 inches
Answer:
n=3 n=5
Step-by-step explanation:
|4n−15|=|n|
Positive
4n−15=n
Subtract 4n from each side
-15 = -3n
Divide by -3
-15/-3 = n
5 = n
negative
4n -15 = -n
Subtract 4n from each side
-15 = -5n
Divide by -5
-15/-5 = n
3 = n
