Answer: The slope between the points (0,-1) and (2,-5) is (-5 - (-1)) / (2 - 0) = -4 / 2 = -2.

Step-by-step explanation:

The area covered by the tiles is 54 square meters.

In this problem we find that 2400 square tiles can cover a rectangular school room and 1350 square tiles if each tile is 5 centimeters longer and 5 centimeters wider. Algebraically speaking, this situation is represented by following formula:

2400 · x² = 1350 · (x + 5)²

Where x is in centimeters.

First, expand and simplify by algebraic properties:

2400 · x² = 1350 · (x² + 10 · x + 25)

2400 · x² = 1350 · x² + 13500 · x + 33750

1050 · x² - 13500 · x - 33750 = 0

Second, find the roots of quadratic equation by quadratic formula:

x₁ = 15 or x₂ = - 15 / 7

Since lengths are positive variables, then only valid solution is x = 15 cm.

Third, calculate the area covered by the tiles:

A = 2400 · (15 cm)²

A = 540000 cm² (54 m²)

Step-by-step explanation:

Answer:

Let y = x - 4, then xy = 60.

Expanding the product on the right side, we have x(x-4) = 60.

Expanding the left side, we have x² - 4x = 60.

Adding 4x to both sides, we have x² = 60 + 4x.

Re-arranging the equation, we have x² - 4x - 60 = 0.

Thus, the quadratic equation is x² - 4x - 60 = 0.

27/128 is the probability that the number of dice showing a two-digit number is equal to the number of dice showing a one-digit number.

Probability means Possibility. It states how likely an event is about to happen.

The probability of an event can exist only between 0 and 1 where 0 indicates that the event is not going to happen i.e. Impossibility and 1 indicates that it is going to happen for sure i.e. Certainty.

I'll take a stab at this one. if the number of dice showing a two-digit number = the number of dice showing a one-digit number, then  2 must show a two-digit number and 2  must show a one-digit number

There are 3 two-digit numbers and 9 one-digit numbers on each die

So....the probability is

It is likely that she is on tiptoe, as a pressure of 1,500,000 Pa is a high pressure for a 60 kg person to be applying with just one foot while standing flat on the ground.

The unit of pressure Pa is equivalent to Newton per square meter

A mass of 60 kg is converted to force by

= m * g

= 60 * 10

= 600 N

Pressure = Force / Area

Area = Force / Pressure

Area = 600 N / 1,500,000 Pa

Area = 0.0004 square meter

Area = 4 square centimeter

This area is much smaller than the foot hence the dancer is tiptoeing

every corner here is 90⁰,because it says so.

QRP would be 90-56 =34⁰ and the opposite corner is the same,so 34⁰

Answer:

Step-by-step explanation:

KRL = QRP, so finding QRP can get us our answer. We were given 56 and 90 because 90 is the degree of a right angle.

A straight line is 180 degrees.

If we subtract 90 and 56 from that 180, we'll find out QRP

180-90=90

90-56=34

Since QRP = 34, that means KRL does also

The ladder can reach up to approximately 6.12 feet on the wall while still being sturdy.

To find the height up the wall that the ladder can make contact with, we need to use the Pythagorean theorem. Let's call the height up the wall h and the distance from the wall to the foot of the ladder d. We know that the ladder is 10 feet long, so we can write:

d² + h² = 10²

Next, we use the angle constraints to relate d and h. The angle the ladder makes with the wall is between π/12 and π/6, so we can use the tangent function to write:

tan(π/12) < h/d < tan(π/6)

Solving for h, we have:

d × tan(π/12) < h < d × tan(π/6)

Finally, to find the maximum height the ladder can reach, we need to find the maximum value of d while still satisfying the inequality. We know that d + 10 = h / tan(π/12), so we can substitute and simplify:

d × tan(π/12) < d ×× tan(π/6) + 10 × tan(π/12)

d < 10 × tan(π/6) / (tan(π/12) - tan(π/6))

Since tan(π/12) < tan(π/6), the denominator is positive, so d is maximized when it is as large as possible. Plugging in the values, we have:

d < 10 × tan(π/6) / (tan(π/12) - tan(π/6)) = 10 × 2 / (√3 - 2) ≈ 9.35

Finally, the maximum height the ladder can reach is:

h = d × tan(π/12) < 9.35 × tan(π/12) ≈ 6.12 feet

So the ladder can reach up to approximately 6.12 feet on the wall while still being sturdy.

The slope will remain constant, thus it will still be 3.

Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size.

Given AB is dilated by a scale factor of 3 to form A'B',

and Point O, which lies on AB, is the center of dilation,

AB has expanded due to the scaling factor, to form A'B'

The image is thus consistent with the preimage according to the laws of dilation.

This suggests that other than the size, the image won't change in any way.

Therefore, the slope will stay the same, the slope of A'B' is 3.
