Answer: medians in a triangle.
The intersection of the three altitudes is the orthocenter.The intersection of the three perpendicular bisectors is the circumcenter.The intersection of the three angle bisectors is the incenter.The intersection of the three medians is the centroid.The graph below shows the altitude, in feet, of a model rocket t seconds after launch. During this time, the rocket
experiences three distinct modes of flight. Initially, the engine accelerates the rocket upward. The rocket then coasts
upward, is slowed by gravity, and eventually begins to fall. Last, a parachute opens and the rocket drifts smoothly
back to the ground.

brian is 6 feet tall and cast a 4 foot shadow. At the same time, a nearby flag pole cast a 20 foot shadow. How tall is the flag pole?
Answer:
30
Step-by-step explanation:
Given:
Brian Height = 6 feet
Brian Shadow Height = 4 foot
Flag Shadow Height = 20 foot
Flag Height = Unknown ??
So we can use cross multiplication
6/4 = x/20
6×20/4 = x
6×20 =120
120÷4 = 30
So x= 30, which is the Flag Height
I wish that I helped you with this.
As per linear equation, the height of the flag pole is 30 feet.
What is a linear equation?A linear equation is an equation that has one or multiple variables with the highest power of the variable is 1.
Given, Brian is 6 feet tall and cast a 4 feet shadow.
Therefore, the ratio of Brain and it's shadow is
= 6/4
= 1.5
A flag pole cast a 20 foot shadow.
Therefore, the height of the flag pole is

30% of the students in a class score an A on the last test. There are 50 students in the class. How many students scores an A on the test?
15
Step-by-step explanation:Percentages represent a proportion of a number. There are 2 ways to find a percent of a whole number.
Multiple of 10
Since 30% is a multiple of 10%, there is a shortcut we can use. We can find 10% and then multiply by 3 in order to find 30%. First, find 10% of 50. Like always, 10% of any number is that number divided by 10 (move the decimal 1 place to the left).
50/5 = 10So, 10% of 50 is 5.0.
Then, to find 30%, multiply 5 by 3.
5*3 = 1530% of 50 is 15.
Multiplication
The more consistent method includes multiplication, this can be used with any percentage. To use this method we need to convert 30% to a decimal. To convert any percentage to a decimal divide by 100 (move the decimal 2 places to the left).
30% / 100 = 0.30Now, we can multiply this decimal by the whole number, 50. This will give us our desired answer.
0.30*50 = 15So, this once again shows that 30% of 50 is 15.

He should have multiplied the sum by 4.
He should have added only the choices for type and transmission.
He should have multiplied only the choices for type and transmission.
He should have multiplied the choices, instead of adding them.
Jordan's error is He should have multiplied the choices, instead of adding them. Thus, the correct option is D.
What are the number of choices?Whenever you have multiple choices, you have to multiply the number of choices you have in different groups to get the final number of choices.
For example, you have to make a sandwich and you can either use white bread or brown bread. Also, you can either use jam or peanut butter or veggies. Therefore, here the number of choices is 6.
White bread and JamWhite bread and Peanut butterWhite bread and VeggiesBrown bread and JamBrown bread and Peanut butterBrown bread and VeggiesSimilarly, Jordan has two choices for type, two choices for transmission, 5 choices for color, and 2 choices for the top.

Find the area to the nearesy square foot of the shaded region below, consisting of a square with a circle cut out of it.
Based on the calculations, the area of the shaded region is equal to 22 square foot.
How to calculate the area of the shaded region?By critically observing the geometric shapes, the area of the shaded region can be calculated by using this formula:
Area of shaded region = Area of square - Area of circle.
Note: The diameter of this circle is equal to the side length of the square because the circumference of this circle lies on the circumference of the square.
Radius = diameter/2 = 10/2 = 5 feet.
For the area of square, we have:
Area of square = S²
Area of square = 10²
Area of square = 100 square foot.
For the area of circle, we have:
Area of circle = πr²
Area of circle = 3.14 × 5²
Area of circle = 78.5 square foot.
Substituting the parameters into the formula, we have;
Area of shaded region = Area of square - Area of circle.
Area of shaded region = 100 - 78.5
Area of shaded region = 21.5 ≈ 22
Area of shaded region = 22 square foot.
