Answer:
11.0
Step-by-step explanation:
Circumfrence = 2 x pi x r.
making radius, r the subject of relation, you.get 11.003184713
Answer:
Hey!
Your answer is 11cm!
Step-by-step explanation:
So to get the radius from the Circumference we need both the Circumference and the value of pi...3.14
Radius = [tex]\frac{C}{2\pi }[/tex] ... (that's the formula)
WE SUBSTITUTE IN:
Radius = 69.1/2 x 3.14
69.1/6.28
This equals = 10.99760656765
BUT 11cm when you round it to the next whole number or 2sf

what does i2x + 3(x - 5) = 20 equal
Answer:
x=7
Step-by-step explanation:
2x+3(x-5)=20
2x+3x-15=20
5x-15=20
5x=35
x=7
Answer:
x = 5
Step-by-step explanation:
2x + 3(x - 5) = 20
simplify
5x - 5 = 20
get the variable and the number on different sides
5x - 5 + 5 = 5x
20 + 5 = 25
5x = 25
now divide each side by 5
5x / 5 = x
25 / 5 = 5
x = 5

the average rain fall in cuba in the summer is 5.3 inches per month. if cuba gets 6.3 inches in june and 7.1 in july how much rain do they need in august to exceed their average
Answer:
They need more than 2.5 inches.
Step-by-step explanation:
average = 5.3
June: 6.3
July: 7.1
August: x
The average of the amounts for June, July, and August is
(6.3 + 7.1 + x)/3
To exceed the average, the average must be greater than 5.3.
(6.3 + 7.1 + x)/3 > 5.3
Multiply both sides by 3.
6.3 + 7.1 + x > 15.9
x + 13.4 > 15.9
Subtract 13.4 from both sides.
x > 2.5
Answer: They need more than 2.5 inches.

Sadie has $1 worth of nickels and dimes. She has twice as many nickels as dimes. Write a system of equations that could be used to determine the number of nickels and the number of dimes that Sadie has. Define the variables that you use to write the system.
The system of equations which can be used to model the scenario are :
n = 2d _____________(1)0.05n + 0.10d = 1 _____(2)Let :
Number of dimes = d Number of nickels = n Number of nickels = 2 × number of dimes n = 2d - - - - - (1)
Worth of nickels and dimes:
A dime = $0.10A nickel = $0.05The total worth of nickel and dimes can be expressed thus :
(Worth per nickel × number of nickels) + (worth per dime × number of dimes) (0.05 × n) + (0.10 × d) = 0.05n + 0.10d = 1Therefore, the systems of equation required are :

1. What is the wavelength of a radio wave broadcast at 150 MHz?
The value of the wavelength will be equal to 2 meters.
It is given that a radio is broadcasting at 150 MHz .
We have to calculate the wavelength.
What is the formula for wavelength ?
The wavelength is given by L = c/f , where c = speed of wave and f is the frequency of wave.
∵ L = c/f
Let's assume c = 3 × 10^8
Given that frequency (f) is 150 MHz .
Wavelength (L) is approximately ;
L= (3 × 10^8 )/ (150,000,000)
L= 2 meters
Thus, the wavelength of a radio wave broadcast at 150 MHz will be equal to 2 meters.

Answer:
Quest 5. No, 2^4 = 16, 2.4 =2 x 4 = 8.
Quest 6. let No. of cells = Nc, let No. of Hours = Nh.
then Nc = (6hrs x 2cells)/1hr = 12 cells.
if 1,024 cells, then
Nh = (1hrs x 1,024cells)/2hrs = 512 hrs.
Quest 7. No, cos 10^7 is only 10,000,000, so 39 & 10 million are not any way equal.
Quest 8. 1 = 1^3, 8 = 2^3, 27 = 3^3, 1 = 1^3, 64 = 4^3, 125 = 5^3,
Quest 9. 2^8 = 2 x 2 x 2 x 2 x 16 = 256, this cos 256 is a product of 8, 2s & there are 4, 2s in 16.
so altogether its all 8, 2s.

Answer:
a. f(1) = -4
b. One value of x for which f(x) = -1 : 2 (or -2)
Step-by-step explanation:
a. To find f(1), we would have to find what the value of the function would be when x = 1. By using the given graph, we can find the f(1) by finding what the y-value is when x = 1. Looking at the graph, we can see that when x = 1, y = -4. Thus, f(1) = - 4.
b. Now we are also asked to find one value of x for which f(x) = -1. In other words, what values of x would make the value of the function equal to -1? We can find values of x for which f(x) = -1 by using the graph and seeing for which x-values would the y-value be -1. We can see that y = -1 at x = -2 and x = 2. So the values of x at which f(x) = -1 are -2 and 2. You can choose either one of these values.
