=》3rd quadrant - both have negative values

Answer:

96 tiles

Step-by-step explanation:

The kitchen floor is rectangular on shape.

The dimensions of the kitchen floor were 8 feet by 12 feet.

Hence, Area of a rectangle = Length × Width

Length = 8ft

Width = 12ft

Hence:

Area = 8ft × 12ft

= 96 ft²

If each tile was 1 square foot, the number of tiles he would need is

1 ft² = 1 tile

96 ft² = x

Cross Multiply

1ft² × x = 96 ft² × 1 tile

x = 96 ft² × 1 tile/1 ft²

x = 96 tiles

Therefore, Mark's father would need 96 tiles

Answer:

A. (4,2)

Step-by-step explanation:

In coordinates, the x-value appears first then the y-value. This means coordinates are set up like, (x,y). So, to solve find the coordinates whose values match one pair of values on the table. Option A has x=4 and y=2. In the last row of the table, you can see the same values with x=4 and y=2. Therefore, A is correct.

Answer:

The answer is 65.97 yd^3

Step-by-step explanation:

The volume of a cone is: v = [tex]\pi r^{2}\frac{h}{3}[/tex]

So, v = [tex]\pi[/tex](3^2)(7/3) = 65.97345 yd^3

The Answer Is H=3.5

have am amazing day <3

Answer:

[tex]h = \frac{7}{2} [/tex]

Step-by-step explanation:

1) Divide both sides by -4.

[tex]h = \frac{ - 14}{ - 4} [/tex]

2) Two negative makes a positive.

[tex]h = \frac{14}{4} [/tex]

3) Simplify 14/4 to 7/2.

[tex]h = \frac{7}{2} [/tex]

Therefor, the answer is 7/2.

Step-by-step explanation:

(x^2 - 2) (5 x^3 - 3)

(x (5 x^2 - 10) - 3) x^2 + 6

Polynomial discriminant:

Δ = -1772976600

Derivative:

d/dx(5 x^5 - 3 x^2 - 10 x^3 + 6) = x (25 x^3 - 30 x - 6)

Indefinite integral:

integral(6 - 3 x^2 - 10 x^3 + 5 x^5) dx = (5 x^6)/6 - (5 x^4)/2 - x^3 + 6 x + constant

Answer:

1/40

Step-by-step explanation:

Probability: (number of ways to achieve the desired result / number of possible results)

For example, if we want a coin to land on heads:

We know there is one way for it to land on heads and two possible outcomes. Thus, the possibility of flipping a head is 1/2.

Using this, we know that there are 5 grey marbles (the desired result) and there are  (5 + 3 + 6 + 2 + 4) total possible outcomes. The probability of drawing a grey marble is then:

5 / (5 + 3 + 6 + 2 + 4) =

5/20 =

1/4

We also know that there are 2 yellow marbles, so the probability of drawing one would be: 2 / 20 = 1/10

To find the probability of both of these events happening right after each other, multiply the probability of them each happening together.

1/4 * 1/10 = 1/40 chance of picking a grey marble and then a yellow marble.

Answer:

20%

Step-by-step explanation:

5 20% = 100%

Answer:

20% is 5$.

Step-by-step explanation:

Ok - these always need a bit of a read to make sure we're answering the right thing.

"What percent..." asks us for a percentage. Ok - good.

"...of 25..." asks us to take the number (25) and multiply it by the percentage we're going to find.

"...is 5" tells us what the answer we're looking for is. So we have:

25  ×  P  =  5

- 25 times some percentage equals 5.

We can treat P as a variable and so can divide both sides by 25:

p = 5/25 = 1/5 = 0.2 = 20%.

6 x -2 = -12

-12 = 3, -4

y = 6x^2 + 3x - 4x - 2

y = 3x(2x + 1) - 2(2x + 1)

(2x + 1) (3x - 2) = 0

2x = -1, 3x = 2

x = -1/2, 2/3

pls give brainliest im trying to level up :))

Answer:

(2x+1)(3x-2)

Step-by-step explanation:

Given :-

We need to factor out the given expression. For that we may use the middle term splitting method. Taking the equation,

[tex]:\implies[/tex] y = 6x² - x - 2

[tex]:\implies[/tex] y = 6x² - 4x + 3x-2

[tex]:\implies[/tex] y = 2x ( 3x -2) +1( 3x -2)

[tex]:\implies[/tex] y = (2x + 1)(3x -2 )

Answer:

Step-by-step explanation:

[tex] \sqrt{81 \times 25 \times 4} [/tex]

Since,

[tex] \sqrt{a \times b \times c} = \sqrt{a} \times \sqrt{b} \times \sqrt{c} [/tex]

Hence,

[tex] = \sqrt{81} \times \sqrt{25} \times \sqrt{4} [/tex]

= 9 × 5 × 2

= 90 (Ans)

Answer:

They are 24, 692 feet aprart

Step-by-step explanation:

Let us assume at the instance we are measuring their position, that Pluto is at the highest point in the air, which is = 24,568 feet, and Goofy is at the lowest point of the sea (that he can go) = 124 feet.

Before we can proceed with the addition, we need to establish a datum, which will serve as the reference point from which the two distances are measured. This definitely is the sea level, because altitude and depth are usually measured above and below sea level.

Pluto's location to the sea level = 24,568 feet

Goofy's Location to the sea level = 124 feet

their distance apart = 24,568 feet + 124 feet =24, 692 feet apart

Answer:

Step-by-step explanation:

From the dot plot of start of school year,

Maximum value of the miles run = 10

Minimum value of the miles run = 5

Range of the data set = 10 - 5

                                    = 5 miles

From the dot plot of End of school year,

Maximum value of the miles run = 10

Minimum value of the miles run = 6

Range of the data set = 10 - 6

                                    = 4 miles

The range at the start of the year was 5 miles and the range at the end of the year was 4 miles.
