"Starting with three, every consecutive line has 2 less than twice the previous line."
this statement means that
your staring line has 3 marbles. You multiply the 3 marblesby 2 so
3x2=6
And then you minus it by 2
6-2=4
which means that you'll get 4 marbles for the next line.
So to get your 6th line, you count how many marbles is on the 5th line but since your diagram doesn't have the 5th line you have to figure out the 5th line by counting how.many marbles is on the 4th line.
4th line = 10 marbles
10×2=20
20-2=18
5th line = 18
18×2=36
36-2=34
So the 6th line has 34 marbles.
Answer:
1/2
Step-by-step explanation:
5/10 = 0.5
0.5 = 4/8 = 3/6 = 2/4 = 1/2.
Whenever you see a fraction where the denominator is exactly twice as big as the numerator, you know that it equals 0.5 or the other fractions that equal 0.5
I believe it might be “b” however im nor sure
Answer:
I explain down below:
Step-by-step explanation:
First, you divide the combined rectangle into separate parts. Then you find the area of the first rectangle. Then the second and/or third one.
After all the areas have been solved, you add all of the areas together.
Hope this helps!
All of a triangles angles add up to 180, this is known as the triangle sum conjecture.
an Iscoceles triangle is a triangle that has two or more congruent sides.
if a triangle is Iscoceles then th e two angles that are made by the congruent sides and base are also congruent.
if you know that one of the angles is 20 that. The sum of the other two angles must be 160.
That means that answer 2 and 4 are incorrect.
Answers 1 and 3 both have a total angle sum of 160. since this is true the correct answer depends on where the known angle is. If it is the angle that is formed by the two congruent sides than the answer is number one. but if it is formed by one of the congruent sides and the base then the answer is number 3.
