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.

ANSWER

x=1.1 or x=-9.1

EXPLANATION

[tex] {x}^{2} + 8x = 10[/tex]

Ad the square of half the coefficient of x to both sides:

[tex]{x}^{2} + 8x + {4}^{2} = 10 + {4}^{2} [/tex]

[tex]{x}^{2} + 8x + 16= 10 + 16[/tex]

The left hand side is now a perfect square.

[tex] {(x + 4)}^{2} = 26[/tex]

Take square root

[tex]x + 4= \pm \sqrt{26}[/tex]

[tex]x = - 4 \pm \sqrt{26}[/tex]

x=1.1 or x=-9.1

Using the quadratic formula, we need to rewrite the given equation to get;

[tex] {x}^{2} + 8x - 10 = 0[/tex]

where a=1, b=8 and c=-10

The solution is given by:

[tex]x = \frac{ - b \pm \: \sqrt{ {b}^{2} - 4ac } }{2a} [/tex]

We substitute the values into the formula to get;

[tex]x = \frac{ - 8\pm \: \sqrt{ {8}^{2} - 4(1)( - 10) } }{2(1)} [/tex]

[tex]x = \frac{ - 8\pm \: \sqrt{ 104 } }{2} [/tex]

[tex]x = \frac{ - 8\pm \: 2\sqrt{ 26 } }{2} [/tex]

[tex]x = - 4\pm \: \sqrt{ 26 } [/tex]

x=1.1 or x=-9.1

to the nearest tenth.

The probability that the selected marble is Green for the considered case is given by: Option B: 1/3

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:

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

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.

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.

Step-by-step explanation:

Final answer:

The tangent of angle A, with angle A opposite side X in a right triangle where X = 10 cm and Y = 24 cm, is approximately 0.4167.

Explanation:

If we have a triangle with sides X = 10 cm, Y = 24 cm, and Z = 26 cm, we can use the tangent function to determine the tangent of angle A, assuming that angle A is opposite the side X. Using the fact that the y-axis passing through the third charge bisects the 24-cm line, we create two right triangles of sides 5, 12, and 13 cm, indicating that the triangle in question is in fact a right triangle, with the two smaller sides being X and Y, and the hypotenuse being Z.

Using the definition of tangent, which in a right triangle is the ratio between the side opposite to the angle and the side adjacent to the angle, the tangent of angle A would be tan(A) = opposite / adjacent. In this triangle, that would mean:

tan(A) = X / Y = 10 cm / 24 cm

Calculating this gives us:

tan(A) ≈ 0.4167

Therefore, the tangent of angle A is approximately 0.4167.

Answer: Brainiest pls

Is the percent increase from 50 to 70 equal to the percent decrease from 70 to 50? Explain. No. ... The ratio for the percent increase from 50 to 70 is 20/50, or 40%. That was my response. I got it right. or Sample response: No. The amounts of change are the same, but the original amounts are different. The ratio for the percent increase from 50 to 70 is 20/50, or 40%. The ratio for the percent decrease from 70 to 50 is 20/70, or about 29%.

Step-by-step explanation:

PERCENT CHANGE

The percentage change from 100 to 120 is 20 %

((y2 - y1) / y1)*100 = your percentage change

Percent Off(where y1=start value and y2=end value)

((120 - 100) / 100) * 100 = 20 %

Step by step workout

step 1 Address the formula, input parameters & values

Formula :

x 100 = Percent Increase (%)

Initial Value X = 50 & New Value Y = 70

Increase = (Y - X)

40 percent increase (%↑) or raise from 50 is 70 or 140% of 50 is 70

Consider the following problem involving stock prices.

In recent years, the stock market has been quite volatile. Suppose your stock investment was initially $100,000. After a period where the value first decreased by 20% and then the value increased by 20%, would the value still be $100,000?

Many people, including some financial advisors, would answer the question in the affirmative; they would say your stock would still be valued at $100,000. But let's compute the result before we answer the question. Since the stock first decreased by 20%, we take 20% of $100,000, which is $20,000. So, the value of the stock would then be $80,000. The 20% increase would be on the $80,000. Taking 20% of $80,000, we obtain $16,000, which means the stock increases in value by $16,000. Therefore, the stocks final value is $96,000. The answer to the question is no since the value has had a net decrease of $4,000.

This answer seems counterintuitive since we had a 20% decrease and a 20% decrease.   But note that the 20% decrease was on a greater value than the 20% increase. The changes were not on the same stock values.

What would be the result if the reverse happened, that is, first have a 20% increase followed by a 20% decrease?

The 20% increase on $100,000 would be an increase of $20,000. So, the new value would be $120,000. We find the 20% of $120,000 is $24,000. Therefore, we would have a decrease of $24,000 for a net value of $96,000. Note that we have obtained the same result. The order of the increase and decrease did not matter, again because the 20% decrease was taken on the greater value than the 20% increase.

The Commutative Property of Multiplication may be used to show that the above two problems will have the same result. First note that 100% of $100,000 is $100,000. A decrease of 20% of the value would mean that the final value would be 80% of the original value since 100% – 20% = 80%. Also, an increase of 20% of the value would mean that the final value would be 120% of the original value since 100% + 20% = 120%. Reword the problems: Find 120% of 80% of $100,000 or find 80% of 120% of $100,000. Translate the problems:

1.20(0.80)(100,000) = 0.80(1.20)(100,000).

The commutative property shows that the two problems are equivalent. Multiplying either side of the equation we obtain our solution of $96,000.

Further note that $96,000 is a 4% decrease from the original $100,000 since we had a decrease of $4,000.

The above problem is a illustration of a common type of problem involving percentages where percents are used to describe how prices, salaries, and other monetary situations change. For instance, the TV you want to buy is on sale for 30% off or you get a 3.5% increase in your salary starting July 1.

Answer:

Final answer is 972 tiles.

Step-by-step explanation:

Given that length of each vinyl tile = 8 in

Given that width of each vinyl tile = 8 in

Then area of 1 vinyl tile = (Length) (Width) = (8)(8)= 64 square inches

Given that length of kitchen = 24 feet = 24 (12 in) = 288 in

Given that width of kitchen = 18 feet = 18 (12 in) = 216 in

Then area of kitchen = (Length) (Width) = (288)(216)= 62208 square inches

Then number of tiles needed [tex]=\frac{62208}{64}=972[/tex]

Hence final answer is 972 tiles.

To find the number of 8 inch by 8 inch tiles needed to cover a floor that is 24 feet by 18 feet, you need to calculate the total area of the floor in inches and then divide by the area of one tile. Thus, for a floor area of 62208 square inches and a tile area of 64 square inches, the number of tiles will be 972.

The first step is to convert the dimensions of the kitchen floor from feet to inches since the size of tiles is given in inches. Therefore, the floor size is 24ft * 12(in/ft) = 288 inches by 18ft * 12(in/ft) = 216 inches. Now, the area of the kitchen floor can be calculated as 288(in) x 216(in) = 62208 sq in.

Since each tile is 8 inches by 8 inches, the area of each tile is 8(in) x 8(in) = 64 sq in. To find out how many tiles are needed, you divide the total area of the kitchen floor by the area of one tile. Thus, 62208 sq in / 64 sq in = 972 tiles. Therefore, you would need 972 tiles to cover the kitchen floor.
