Answer:
15
Step-by-step explanation:
Red counters = 35
Number of green counters = x
P(picking a green counter) = 0.3
Probability = required outcome / Total possible outcomes
Required outcome = number of green counter
Total possible outcomes = green counter + red counter
Hence,
0.3 = x / (35+x)
0.3(35 + x) = x
10.5 + 0.3x = x
10.5 = x - 0.3x
10.5 = 0.7x
x = 10.5 / 0.7
= 15
Number of green counters = 15

Adrian is going to invest $9,900 and leave it in an account for 10 years. Assuming the interest is compounded continuously, what interest rate, to the nearest hundredth of a percent, would be required in order for Adrian to end up with $17,700?
Answer:
did you ever get the answer bc I am struggling on this, pls help.
Step-by-step explanation:
Answer: 5.81%
Step-by-step explanation: Delta Math
A = 17700. P = 9900. t = 10
17700 = 9900e^r(10)
17700/9900 = 9900e^10r/9900
1.7878788 = e^10r
In(1.7878788) = In(e^10r)
In(1.7878788) = 10r
In(1.7878788)/10 = 10r/10
0.058103 = r
5.8103% = r
r = 5.81%

Determine if the side lengths given form a triangle. Justify your response. 6.4 mm, 12.9 mm, 14.2 mm
Answer:
Step-by-step explanation: Yes I think since if you add 12.4 and 6.4 your answer is more then 14.2 so yes it is possible
Answer:
Yes, it does form a triangle
Step-by-step explanation:
According to the first triangle inequality theorem, the lengths of any two sides of a triangle must add up to more than the length of the third side. This means that the given side lengths DO form a triangle. 6.4+12.9=19.3 which is more than 14.2.

Calculate the length of side x.
Answer:
4
Step-by-step explanation:
we can see that the big square is twice as large as the small one
which makes x=4
The scale factor is 2. Then the value of the variable 'x' is 1 cm.
What is dilation?Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered. There is no effect of dilation on the angle.
The scale factor is given as,
SF = 14 / 7
SF = 2
Then the value of the variable 'x' is calculated as,
x = 8 / SF
x = 8 / 2
x = 4 cm
The scale factor is 2. Then the value of the variable 'x' is 1 cm.

find the length of the arc intercepted by a central angle of 1.5 radians in a circle of radius 9 cm.
Answer:
13.5 cm
Step-by-step explanation:
The length of an arc depends on the radius of a circle and the central angle θ. We know that for the angle equal to 360 degrees (2π), and the arc length is equal to circumference. Hence, as the proportion between angle and arc length is constant, we can say that:
L/θ = C/2π (C = Circumference = 2πr)
L/θ = 2πr/2π,
L/θ = r,
L = r*θ = 9 cm * 1.5 = 13.5 cm
