Answer:
The tree is about 8 feet.
Step-by-step explanation:
7 2/3 = 7.6 as a fraction.
30 1/5 = 30.5 as a fraction.
Know, we must divide 30.5 by 7.6.
30.5 ÷ 7.6 = 4 when rounded to the nearest whole number.
Since we know that the stake is 2 feet, we must multiply this by 4, since the other shadow is 4 times the amount of the stake.
2 x 4 = 8
This means the tree is about 8 feet.
A. 2,-2,2,-2,2,-2,2
C. 10,5,2.5,1.25,0.625,0.1325
and
D. 1,2,4,8,16,32
Are all geometric sequences
This means that each sequential # is derived by either multiplying or dividing by a number.
For instance, A. is found by multiplying each by - 1, B. is found by multiplying each by 1/2 (0.5), and D. is found by multiplying each by 2
Answer:
Step-by-step explanation:
If the triangle is equilateral, it means that all the sides are the same. Since there are 3 sides in a triangle, each side is 24/3 = 8
Now, in order to find the height, we can use the pythagoeren theroem. Notice that the height bisects(splits the side) into two equal parts, which each part having the length 8/2 = 4
So we have

Answer:
135 to nearest whole number.
Step-by-step explanation:
∑ 5(4/3)^(k-1) from k = 1 to k = 8.
First term = 5 , second term = 5*4/3
This is a Geometric series with first term a1 = 5 and common ratio r = 4/3.
The sum of n terms = a1(r^n - 1) / (r - 1).
The sum of 8 terms is given by 5 * (4/3)^8 - 1) / ( 4/3 - 1)
= 135 to the nearest whole number.
