Answer:
Height of the kite = 36 feet
Step-by-step explanation:
Triangle attached in the figure shows the complete picture,
I am sitting at point A, string connecting the kite and me is side AC, height of the kite from the ground is side BC and side AB representing the distance between me and the kite.
Length of side BC = h
Length of side AC = 39 feet
Length of side AB = 15 feet
By applying Pythagoras theorem in ΔABC,
AC² = AB² + BC²
(39)² = (15)² + h²
h² = 1521 - 225
h² = 1296
h = √1296
h = 36 feet
Therefore, kite is at 36 feet height.
Answer:
Step-by-step explanation:
Even number on spinners are 5 out of 10 probability of it is 1/2 and probablity of coin landing on tails also 1/2
Probability of compound event is probability of first event multiplied by probability of second even
So 1/2×1/2=1/4
Second one is 9/10×1/2=9/20
Answer:
Hey there so this looks harder then it really is. All you need to do is this..
700x5.5%= 38.50
then times that by 4 to get your total over the 4 years.
Simple interest=154
Step-by-step explanation:
The geometric series with 4th term as 10 and 7th term as 80 has the sum of the first tenth terms as 1278.75.
<h3>How to find sum of terms in geometric series?</h3>
aₙ = arⁿ⁻¹
where
- a = first term
- r = common ratio
- n = number of terms
Therefore,
10 = ar³
80 = ar⁶
Hence,
a = 10 / r³
80 = (10 / r₃) r⁶
80 = 10r³
r³ = 80 / 10
r = ∛8
r = 2
a = 10 / 2³
a = 10 / 8 = 5 / 4
The sum of 10 terms can be calculated as follows:
Sₙ = a(rⁿ - 1) / r - 1
Sₙ = 5 / 4 (2¹⁰ - 1) / 2 - 1
Sₙ = 5 / 4 (1024 - 1) / 1
Sₙ = 1.25(1023)
Sₙ = 1278.75
