Answer:
approximately 21 years
Step-by-step explanation:
-From the problem, we are given the equation I = Prt
-We're also given three numbers
-From that, we can determine which number should be plugged into the equation:
- P = $1234 (this is the principle amount/original amount)
- r = 0.09 (this is the rate of simple interest)
- I = $2308 (this is the ending amount)
-The only value we are not given is t as we need to solve for this value
-Now plug all these values into the equation:
- I=Prt
- $2308 = ($1234)(0.09)t
- $2308 = 111.06t
- Divide both sides by 111.06
- t = 20.7816
It takes approximately 21 years for the investment amount to be worth $2308.
Answer:
1/32
Step-by-step explanation:
P(heads) = 1/2
P(5 heads) = (1/2)⁵ = 1/32
Answer:
Circumference = pi x diameter
220 = pi x
220/3.14 = 70.06 = 70.1
Hope that answers your question
(Attention: the top answer is only valid if the question asks you to use 3.14 as pi, if the question tells you to use the digit Π, then the answer is 70.0)
Step-by-step explanation:
Answer:
According to triangle theorems, all the interior angles are equal to 180°. Since we know that angles A and C are 75° and 90°, angle B will equal 180° - 75° + 90° = 15°
We can use the sine of angle A to find x,
Sin75° = 125/x
Sin75°(x) = 125/x(x)
Sin75°(x)/sin75° = 125/sin75°
x = approximately 129.4
To find y, we can use the tangent of angle B:
Tan15° = y/125
Tan15°(125) = y/125(125)
Tan15°(125) = y
y = approximately 33.5
