Answer:

The mechanical energy is not conserved

Step-by-step explanation:

Recall that the law of conservation of energy states that in an isolated system (no external forces acting on it), the mechanical energy is conserved.

A skier skiing down a slope is not an isolated system in this case because the friction of the snow causes some of the mechanical energy to convert to thermal energy.

Step-by-step explanation:

When we subtracting variables with exponent, both should have same exponents

6.28 * 10⁶ -  1.256*10⁵ = 62.8 *10⁵ - 1.256*10⁵

                                    = (62.8 - 1.256) *10⁵

                                   = 61.544 *10⁵

therefore there is enough buffer solution in the bottle for all 13 experiments

Step-by-step explanation:

We're going to simplify the problem with exponents.

Exponents are a shortened way for explaining how many times a number will multiply itself.

Example:

[tex]3 \times 3 \times 3. [/tex]

[tex] \: the \: number \: is \: multiplying \: by \: itself \: \: 3 \: times. \: the \: exponent \: is \: represented \: as: \:[/tex]

[tex] {3}^{3} [/tex]

We can identify that:

[tex]10 \times 10 = {10}^{2} [/tex]

[tex]( - n) \times ( - n) \times ( - n) = ( - n)^{3} [/tex]

Therefore,

[tex] {10}^{2} \times ( - n)^{3} [/tex]

Answer:

25 pizzas

Step-by-step explanation:

Here, we can find the unit rate, also known as the constant of proportionally. This means we are looking for the pizza amount in 1 hour.

The pizza to hour ratio is in the form [tex]125:5[/tex], so the most logical thing to do here is divide both sides of the ratio by 5 to get 1 alone.

[tex]125/5=25[/tex]

Answer: 25

Step-by-step explanation: 125 pizzas divided by 5 hours = 25 pizzas per hour

Step-by-step explanation:

The time taken for Cameron to complete the race is  6 hours, 15 minutes.

The time taken for Cameron to complete the race is known as time of motion. The time of motion is calculated as follows;

time = distance/speed

time = 74/11.84

time = 6.25 hours

The time is converted to to hours and minutes as follows;

time = 6 hours + 0.25 hours

time = 6 hours + (60 mins x 0.25 hours)

time = 6 hours, 15 minutes

Thus, the time taken for Cameron to complete the race is  6 hours, 15 minutes.

8.25 feet² → area of the sail

Step-by-step explanation:

Base (b) = 3 feet

Height (h) = 5 ½ = 11/2

Area of the sail / triangle

= ½ bh

= ½ × 3 × 11/2

= 33/4

= 8.25 feet²

Hope it helps ⚜

[tex]base = 3 \: ft[/tex]

[tex]heigh = 5 \frac{1}{2} \: ft[/tex]

the area of the triangle sail.

[tex]5 \frac{1}{2} = 5.5[/tex]

[tex]a = \frac{hb}{2} [/tex]

[tex]a = \frac{5.5 \times 3}{2} [/tex]

[tex]a = 8.25 \: {ft}^{2} [/tex]

hence, the area of the triangular sail is 8.25 square feets.

The ratio of the length AC to BC is 11:18

The formula for calculating the distance between two points is expressed as:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

For the length AC
[tex]AC = \sqrt{(-9)^2+(6)^2} \\AC = \sqrt{(-14+5)^2+(12-6)^2} \\AC = \sqrt{81+36} \\AC\approx 11[/tex]

For the length of BC
[tex]BC = \sqrt{(15)^2+(10)^2} \\BC = \sqrt{225+100} \\BC\approx 18[/tex]

Hence the ratio of the length AC to BC is 11:18
