Find the zeros for (x+2)(x-4)

Answers

Answer 1

Answer:

x = -2 or x = 4

Step-by-step explanation:

The zeros:

(x + 2)(x - 4) = 0 ⇔ x + 2 = 0 or x - 4 = 0

x + 2 = 0          subtract 2 from both sides

Answers

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

Compute the number of vinyl tiles, measuring 8 in. each side, needed to tile a kitchen measuring 24 ft. by 18 ft. tiles.

Answers

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.

Final answer:

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.

Explanation:

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.

c.
314 sq. cm
b.
452 sq. cm
d.
154 sq.cm

Answers

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.

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

Answers

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

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]

Use the discriminators to determine the number of solutions for the quadratic equation.

Show work thanks

Answers

Answer:

no real solutions

Step-by-step explanation:

For a quadratic in standard form : y = ax² + bx + c : a ≠ 0

The value of the discriminant

Δ = b² - 4ac informs about the nature of the solutions

• If b² - 4ac > 0 then 2 real and distinct solutions

• If b² - 4ac = 0 then 2 real equal solutions

• If b² - 4ac < 0 then no real solutions

For y = 3x² + 7x + 6

with a = 3, b = 7, c = 6, then

b² - 4ac = 7² - (4 × 3 × 6) = 49 - 72 = - 23

Since b² - 4ac < 0 the equation has no real solutions

How many grams of hydrocortisone are in a 120g of 4% ointment

Answers

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.

Final answer:

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.

Madison reads 24 pages of her book each day. She has read for 9 days & is exactly halfway through reading her book. What is the total number of pages in Madison’s book?

Answers

Answer:

432 pages.

Step-by-step explanation:

We know Madison reads 24pgs/ per day. She reads for nine days, so  she reads 24*9 pages, or 216.

We know also that this is halfway through her book, so 2*216= the whole book, so the book has 432 pages

So 24 pages per day. Meaning in 9 days she would read [tex]24\times9=216[/tex], and if that is half of the pages in the book then the total must be [tex]216\times2=432[/tex] pages.

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.

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]
