Find the surface area of a sphere with a diameter 12 cm. Round your answer to the nearest whole number.
a.
768 sq. cm
c.
314 sq. cm
b.
452 sq. cm
d.
154 sq.cm
Answer:
144*pi cm^2
Step-by-step explanation:
The formula for the surface area of a sphere is A = 4*pi*r^2.
If the diameter is 12 cm, the radius, r, is 6 cm.
Thus, in this case, the surface area of the sphere is
A = 4*pi*(6 cm)^2 = 144*pi cm^2.
Answer:
Surface area = 452 square cm.
Step-by-step explanation:
surface area of a sphere with a diameter 12 cm
Diameter = 12 cm
Radius = diameter divide by 2= [tex]\frac{12}{2} =6[/tex]
Surface area of a sphere = [tex]4\pi r^2[/tex]
Where 'r' represents the radius of the sphere
[tex]4\cdot \pi \cdot 6 \cdot 6= 452.3893421[/tex]
Now round the answer to nearest whole number
Surface area = 452 square cm.

For the first 3 letters slot:
For the 1st slot, we can pick any of the 26 alphabets
For the 2nd slot, we can pick any of the 25 remaining alphabets (since 1 is already taken)
For the 3rd slot, we can pick any of the 24 remaining letters (since 2 is already taken)
For the three digits slot:
For the 1st slot, we can pick any one of the 10 digits
For the 2nd slot, we can pick any one of the 9 digits left, since 1 is taken already
For the 3rd slot, we can pick any one of the 8 digits left, since 2 is already taken
The number of license plates, thus, would be all of these multiplied together:
26 * 25 * 24 * 10 * 9 * 8 = 11,232,000
6) Solve for x. 2/3 (x + 7) = 10
A)22
B)8
C)- 1 /3
D)41/ 3
For this case we must find the value of the variable "x" of the following equation:
[tex]\frac {2} {3} (x + 7) = 10[/tex]
We multiply by 3 on both sides of the equation:
[tex]2 (x + 7) = 30[/tex]
We divide between 2 on both sides of the equation:
[tex](x + 7) = 15\\x + 7 = 15[/tex]
We subtract 7 on both sides of the equation:
[tex]x = 8[/tex]

Subtract 5x−2 from −3x+4 . What is the answer? −8x+6 −8x+2 8x−6 2x + 2
Answer:
-8x + 6
Step-by-step explanation:
Subtract "5x-2" from "-3x + 4". Set the equation.
(-3x + 4) - (5x - 2) = Answer (A)
First, distribute -1 to all terms within the second parenthesis.
-3x + 4 - 5x + 2 = A
A = -5x - 3x + 4 + 2
Simplify. Combine like terms (terms with the same amount of variables).
A = (-5x - 3x) + (4 + 2)
A = -8x + 6
-8x + 6 is your answer, or the first answer choice.

The number of license plates on a car is measured in the __. A.ones B.thousands C.hundreds D.tens
Answer:
A.ones
Step-by-step explanation:
Depending on the state and country, cars can have 1 or 2 license plates on them. The one mandatory is in the back. In some places, the cars also have a license plate in the front of the car.
So, since the answer is either 1 or 2, the range for that answer is under 10... so it's a single digit... making it a measure in ones.
The number of tires on a car is also measured in ones.

A worker at the zoo calculates the amount of fish, in pounds, needed in the weekly diet of an eagle and a bear.
The eagle eats 6 pounds of food each week, and 60% of that weight must be fish.
The bear eats 105 pounds of food each week, and 25% of that weight must be fish.
The zoo increases the amount of food that the bear eats each week to 115 pounds. What is the percent increase in the amount of food that the bear eats each week? Round your answer to the nearest tenth of a percent.
____________________________________________________
Answer:
Your answer would be a 9.5% increase.
____________________________________________________
Step-by-step explanation:
In order to find the answer to your question, we would need to get the amount it's changing by, divide it by it's original, and multiply it by 100.
Your equation should look like this:
[tex]Change/Original * 100[/tex]
Important information in the question:
105 pounds
115 pounds (increase in amount of food that bear eats)
With the information above,we can plug those numbers into our equation.
Since we need to find the change, we would subtract 115 and 105 to get 10. 10 is our change in this scenario.
Our original started at 105, so that'll be our original in our equation.
When you plug in the information, your equation should look like this:
[tex]10/105*100[/tex]
Now you solve:
[tex]10/105*100\\\\0.0952 * 100\\\\=9.523[/tex]
We have to round to the nearest tenth, and the tenth place is the number right after the decimal place.
Since 2 is not a big enough number to round the 5, we would keep the number as 5. Therefore, your answer would be 9.5
Your FINAL answer would be 9.5%

A marble is randomly selected from a bag containing 3 Red marbles, 3 Blue marbles, and 3 Green marbles. What is the probability that the selected marble is Green?
A) 3
B) 1/3
C) 1/9
D) 1/2
Answer:B 1/3
Step-by-step explanation:
3/9=1/3
The probability that the selected marble is Green for the considered case is given by: Option B: 1/3
How to calculate the probability of an event?Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.
Then, suppose we want to find the probability of an event E.
Then, its probability is given as
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)}[/tex]
where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.
Given that:
Bag has 3 green, 3 red, and 3 blue marbles.A marble is selected at random.To find: P(selected marble is green)
Take:
E = event that a marble selected at random is green.
Numbre of cases in which E can be done is 3 (as there are 3 green marbles).
Number of total cases = 3+3+3 = 9 (total 9 marbles, each can come as an outcome).
Thus, we get:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)} = \dfrac{3}{9} = 1/3[/tex]
Thus, the probability that the selected marble is Green for the considered case is given by: Option B: 1/3

There are 6 green, 8 red, and 6 yellow marbles in a bag. You choose a marble without looking, put it aside, and then choose another marble without looking. Use the Multiplication Rule to find the specified probability, entering it as a fraction.
Find the probability that you choose a red marble, followed by a yellow marble, followed by a green marble.
The probability that you choose a red marble, followed by a yellow marble, followed by a green marble is
Answer:
8/20 red marbles
6/20 yellow marbles
6/20 green marbles
Step-by-step explanation:
All of them added together is 20 and there is a probability of choosing 8 red marbles, 6 green marbles, and 6 yellow marbles?
Answer:
[tex]\frac{4}{95}[/tex]
Step-by-step explanation:
Total number of marbles in the bag = [ 6 green + 8 red + 6 yellow ] = 20
Then probability of choosing red marble = 8/20
total number of remaining marbles = 19
Then probability of choosing yellow marble = 6/19
total number of remaining marbles = 18
Then probability of choosing green marble = 6/18
Hence required probability that you choose a red marble, followed by a yellow marble, followed by a green marble [tex]=\frac{8}{20}\cdot\frac{6}{19}\cdot\frac{6}{18}[/tex]
[tex]=\frac{4}{95}[/tex]
Hence final answer is [tex]\frac{4}{95}[/tex]
How many grams of hydrocortisone are in a 120g of 4% ointment
To answer this, you can use a proportion.
We're trying to figure out what a portion of the 120g tube of ointment so that is our first side of the proportion: ?/120
We know that we can represent percentages as fractions by placing the percent over 100. So this is our second side of the proportion: 4/100
Our partially completed proportion is this: ?/120=4/100
Cross multiply 120 and 4: 120*4=480
Divide the product by 100: 480/100=4.8
So, there is 4.8g of hydrocortisone in the ointment.
To find the amount of hydrocortisone in a 120g of 4% ointment, convert the percentage to a decimal and multiply by the total weight. This calculation gives us 4.8 grams of hydrocortisone.
Explanation:Hydrocortisone is a medication used to treat various conditions such as allergic reactions, eczema, and psoriasis. In your question, you want to find the amount of hydrocortisone in a 120g of 4% ointment. The '%' sign in this context is referring to the weight of the substance (hydrocortisone) over the total weight of the solution (ointment). So, to find the amount of hydrocortisone in the ointment, you multiply the total weight of the ointment by the percentage of the substance.
Step 1: Write the percentage as a decimal. 4% becomes 0.04.
Step 2: Multiply the weight of the total ointment by the decimal.
In this case, 0.04 * 120g = 4.8 grams.
So, there are 4.8 grams of hydrocortisone in a 120g of 4% ointment.

a circle has a radius of 9. An arc in this circle has a central angle of 120°. What is the length of the arc?
Answer:
6pi or about 18.8 units
Step-by-step explanation:
See attached file
To calculate the arc length of a circle with a 120° central angle and a 9-unit radius, multiply the fraction of the circle (1/3) by the circle's circumference (2πr) to find the arc length is 6π units.
Explanation:To find the length of an arc with a central angle of 120° in a circle with a radius of 9, we use the formula for arc length. The arc length (As) is proportional to the angle of rotation, which in this case is 120° or θ = 120° ÷ 360°.
The circumference (C) of a circle is given by the formula 2πr, where r is the radius. For a full revolution (360°), the arc length is equal to the circumference. For an angle θ, the arc length is given by:
As = (θ/360°) × 2πr
Using the radius r = 9 and θ = 120°, we calculate:
As = (120°/360°) × 2π(9)
As = (1/3) × 18π
As = 6π
The arc length is 6π units, which is slightly less than 19, as π is approximately 3.14159.
