Your question isn't clear. But I infer this is the clear rendering of it;
How many diagonals does a polygon have with 5 sides, but with 6 sides?
Answer:
a. For 5 sides= 5
b. For 6 sides= 9
Step-by-step explanation:
Remember, this is the formula to calculate the number of diagonals of a polygon;
n (n-3) / 2 where n is the sides.
Thus,
for 5 sides= 5 (5-3) /2
= 5 (2) /2 = 10/2= 5
for 6 sides= 6 (6-3) /2
= 6 (3) /2 = 18/2= 9
Consider the equation
1) First row of the table
Set x=0 and solve as follows:
The answer is y=20 and the pair x-y is (0,20)
2) Second row
Set x=1 and solve, as follows:
The answers are y=10 and (1,10)
3) Third row.
Set y=0 and solve as follows:
The answers are x=2 and (2,0)
Answer:
true
Step-by-step explanation:
models are a smaller example of an original object
#5). In a triangle, the angles track the sides in some interesting ways.
-- If all of the sides are the same length, then
the angles are all the same size.
-- If two sides are the same length, then
two of the angles are the same size.
-- If the sides are all different lengths, then
all of the angles are different sizes.
#5). All of the sides are different lengths.
That's called a "scalene" triangle.
(You're supposed to know that by now.)
One of the angles is more than 90 degrees.
That's called an "obtuse" angle.
If a triangle has an obtuse angle in it, it can't have more than
one of them, and it's called an "obtuse triangle".
#6). All of the sides are different lengths.
That's called a "scalene" triangle.
(You're supposed to know that by now.)
All of the angles are less than 90 degrees.
Those are called "acute angles".
A triangle with three acute angles is called an "acute triangle".
Answer: Moses pays $2.50, and Marvin pays $1.50.
Step-by-step explanation: To solve this question, you have to find the unit rate.
8 pens for $4
4/8= 0.5/1
So, one pen is equal to 50¢.
Then, you just have to multiply how many pens each one buys by the price of one pen.
0.5*5=2.5
0.5*3=1.5
When you add them together, you come up with the amount the question have in the beginning.
2.5+1.5= 4
To conclude, Moses pays $2.50, and Marvin pays $1.50.
