Answer:
80 percent of the students are right handed while the 20 percent are left handed
Answer: A
400/500=n/100
or 80%
Step-by-step explanation:
One ratio should represent the numbers of students, and the other ratio should show the percent out of 100.
There are 400 right-handed students out of 500; this ratio is 400/500
The percent, n, is unknown, so this ratio is n/100

The equation to support the mathematical thinking will be x + 189 = 192 and the numbers needed is 3.
How to calculate the value?It should be noted that the information stated that she needs enough tiles to make three rows with 63 tiles in each row. The number of times needed will be:
= 63 × 3
= 189 tiles
The number of times that Miss Garcia need to make the border tiles cell in boxes of eight tiles in each box will be:
= 192 - 189 = 3
Therefore, 3 tiles are needed. It should be noted that 192 is the multiple of 8 closest to 189.
The equation to support the mathematical thinking will be:
x + 189 = 192
x = 192 - 189

Describe three different ways you can determine that an angle is a right angle.
The three different ways you can determine that an angle is a right angle are as follows:
B) You can determine whether an angle is right if it is marked with a right angle symbol.
D) You can determine whether an angle is right if the angle is a vertical pair with a right angle.
E) You can determine whether an angle is right if the angle forms a linear pair with a right angle.
What is a right angle?A right angle can be defined as a type of angle that is formed by the intersection of two (2) straight lines at 90 degrees. This ultimately implies that, a right angle has a measure of 90 degrees.
In conclusion, we can reasonably infer and logically deduce that all right angles are marked with a right angle symbol and they are formed as a linear pair.

Suppose that both of the events you have just analyzed are partly responsible for the increase in the price of pizzas. Based on your analysis of the explanations offered by the two groups of students, how would you figure out which of the possible causes was the dominant cause of the increase in the price of pizzas?.
The supply curve swings left along the demand curve, raising the price of the pizza shops to close. If individuals just have a greater interest in beer, the demand curve will shift to the right, which will cause the price to rise as the supply curve is moved to the right. Apply this knowledge to the rest of the analysis.
If the price increase was modest, then the movement in supply in the pizza market must have outweighed the shift in demand. The supply shift in the pizza market must have been greater than the demand shift if the equilibrium amount of pizzas declines. The price of pizzas must have changed as a result of whichever modification happened first. If the amount of pizzas in the equilibrium market falls, the demand shift must have been greater than the supply shift.
The demand curve changes to its proper position. It happens as a result of people switching to eating pizza instead of pizzas. The new equilibrium price rises as a result of the new demand curve and the existing supply curve.
A rise in supply and a decline in demand will result in a decrease in the equilibrium price, but the impact on the equilibrium quantity cannot be predicted. Consumers now place less significance on price for any quantity, and producers are willing to simply accept a lower price; as a result, the price will decrease.

Amy studied 3- hours for her Biology test. She studied half as long for her math test as she did for her biology test. How long did she study for her math test?
Answer:
90 minutes or 1 hour and 30 minutes
Step-by-step explanation:
Hey there!
In order to find out how long Amy studied for her math test, all we need to do is divide 3 hours by 2
First of all, we can convert 3 hours to 180 minutes since there are 60 minutes in 1 hour
Now, we divide 180 and 2
180/2 is 90
This means, Amy studied 90 minutes or 1 hour and 30 minutes for her math test
Let the graph of g be a translation 4 units left followed by a horizontal shrink by a factor of 1/3 of the graph of f(x)=x²+x. Write a rule for g
The transformed function is:
g(x) = (3*(x + 4))² + (3*(x + 4))
How to write the transformed function?Here we have the function:
f(x) = x² + x
Now we want to apply a translation of 4 units to the left, followed by a horizontal shrink by a factor of 1/3.
First, the translation is written as:
g(x) = f(x + 4)
Now the shink will give:
g(x) = f( 3*(x + 4))
Replacing the actual function we will get:

In the figure, m/3= (3x+15)° and mZ8= (x+100)°. Find the value of x. Then calculate the measure of Z4.
Value of x = 42.5 ° and measure of angle 4 = 37.5 ° .
measure of angle 3 = measure of angle 8
( 3 x + 15 ) ° = ( x + 100 ) °
2 x = 85
x = 42.5 °
measure of angle 3 + measure of angle 4 = 180 °
measure of angle 3 = ( 3 x + 15 ) °
= ( 3 * 42.5 ) + 15
= 142.5 °
Hence , measure of angle 4 = 180 - 142.5 ° = 37.5 ° .

We are also given that:
a / b < c / d …(1)
c / d < e / f …(2)
Multiply (1) and (2), we get that:
