A glass paperweight is shown below.
The paperweight is a hemisphere with diameter 9cm..
Find the surface area of the paperweight.
Answer:
[tex]A=190.75\ cm^2[/tex]
Step-by-step explanation:
The diameter of a hemisphere, d = 9 cm
Radius, r = 4.5 cm
We need to find the surface area of the paperweight. The formula for the surface area of a hemisphere is given by :
[tex]A=3\pi r^2\\\\A=3\times 3.14\times (4.5)^2\\\\A=190.75\ cm^2[/tex]
So, the surface area of the paperweight is [tex]190.75\ cm^2[/tex].

A restaurant customer left $1.80 as a tip. The tax was 7% and the tip was 20% of the after-tax cost. What was the total bill?
Your answer is
Assume that total bill = x,
tax was 7 % and tip( 1.8) was 20% of ( tax + bill)
equation : ( x+0.07x)*0.2= 1.8
so, 1.07x= 9
Total bill= 8.41

Determine whether the given procedure results in a binomial distribution. If not, state the reason why?
Rolling a single "loaded die 19 times, keeping track of the numbers that are rolled.
a. Not binomial: the trials are not independent.
b. Not binomial: there are more than two outcomes for each trial.
c. Procedure results in a binomial distribution.
d. Not binomial: there are too many trials.
Answer:
b. Not binomial: there are more than two outcomes for each trial.
Step-by-step explanation:
Binomial probability distribution:
We need
Fixed number of trials.
Independent trials.
Each trial can be reduced to a yes/no proposition.
Rolling a single "loaded die 19 times, keeping track of the numbers that are rolled.
There are six possible outcomes(1,2,3,4,5,6), so cannot be reduced to a yes/no proposition, and the answer is given by option b.

4x+3(2x-1)-4x i need help
Answer:
x=0.5
Step-by-step explanation:
Simplifying
4x + -3(2x + -1) + -4x = 0
Reorder the terms:
4x + -3(-1 + 2x) + -4x = 0
4x + (-1 * -3 + 2x * -3) + -4x = 0
4x + (3 + -6x) + -4x = 0
Reorder the terms:
3 + 4x + -6x + -4x = 0
Combine like terms: 4x + -6x = -2x
3 + -2x + -4x = 0
Combine like terms: -2x + -4x = -6x
3 + -6x = 0
Solving
3 + -6x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3' to each side of the equation.
3 + -3 + -6x = 0 + -3
Combine like terms: 3 + -3 = 0
0 + -6x = 0 + -3
-6x = 0 + -3
Combine like terms: 0 + -3 = -3
-6x = -3
Divide each side by '-6'.
x = 0.5
Simplifying
x = 0.5

Answer: 3
Step-by-step explanation:
A term is a group of numbers and variables.
In your expression, there are 3 term: 3k, 10, and 5n^3A coefficient is just the number attached to the variable.
In the term 3k, the first one in your expression, the 3 is the coefficient because it is being multiplied by an unknown, k. There is also another term with a variable in your expression: 5n^3. 5 would be the coefficient because it is being multiplied by an unknown, n, multiplied by itself three timesA constant is just a number.
In your expression, 10 is a constant because it doesn't have a variable, so no matter what the other variables are, that term will always stay 10Hope this helps :)

Georgia is 7 years younger than 5 times the age of her daughter, Veronica. Veronica will be 14 in 6 years. Part A
Write and evaluate an expression to show Veronica’s age.
Enter the correct answers in the boxes.
Answer:
Veronica's age now =8 years
Step-by-step explanation:
Veronica's age now = x years
Georgia's age now = 5x - 7
Veronica age after 6 year = 14
x + 6 = 14
x = 14 - 6
x = 8 years
Find all solutions of the equation in the interval [0, 2π). 2cosθ+ 1= 0
Hello!
[tex]\large\boxed{\frac{2\pi}{3} \text{ and } \frac{4\pi}{3}}[/tex]
2cosФ + 1 = 0
Begin by isolating for cosФ. Subtract both sides by -1:
2cosФ = -1
Divide both sides by 2:
cosФ = -1/2
Using the unit circle, we know that from [0, 2π), values that have a cosine of -1/2 are 2π/3 and 4π/3.
Therefore, the solutions of this equation are:
Ф = 2π/3 and 4π/3
