Nina skated for 2 hour 14 mins she stopped at 8:24 what time did she start skating

Answer:

X=2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2(5.5x+1)=24

(2)(5.5x)+(2)(1)=24(Distribute)

11x+2=24

Step 2: Subtract 2 from both sides.

11x+2-2=24-2

11x=22

Step 3: Divide both sides by 11.

11x/11=

22/11

X=2

Hope this helps

Answer:

π

Step-by-step explanation:

Solving without L'Hopital's rule:

lim(x→0) sin(π cos²x) / x²

Use Pythagorean identity:

lim(x→0) sin(π (1 − sin²x)) / x²

lim(x→0) sin(π − π sin²x) / x²

Use angle difference formula:

lim(x→0) [ sin(π) cos(-π sin²x) − cos(π) sin(-π sin²x) ] / x²

lim(x→0) -sin(-π sin²x) / x²

Use angle reflection formula:

lim(x→0) sin(π sin²x) / x²

Now we multiply by π sin²x / π sin²x.

lim(x→0) [ sin(π sin²x) / x² ] (π sin²x / π sin²x)

lim(x→0) [ sin(π sin²x) / π sin²x] (π sin²x / x²)

lim(x→0) [ sin(π sin²x) / π sin²x] lim(x→0) (π sin²x / x²)

π lim(x→0) [ sin(π sin²x) / π sin²x] [lim(x→0) (sin x / x)]²

Use identity lim(u→0) (sin u / u) = 1.

π (1) (1)²

π

Solving with L'Hopital's rule:

If we plug in x = 0, the limit evaluates to 0/0.  So using L'Hopital's rule:

lim(x→0) [ cos(π cos²x) (-2π cos x sin x) ] / 2x

lim(x→0) [ -π cos(π cos²x) sin(2x) ] / 2x

-π/2 lim(x→0) [ cos(π cos²x) sin(2x) ] / x

Again, the limit evaluates to 0/0.  So using L'Hopital's rule one more time:

-π/2 lim(x→0) [ cos(π cos²x) (2 cos(2x)) + (-sin(π cos²x) (-2π cos x sin x)) sin(2x) ] / 1

-π/2 lim(x→0) [ 2 cos(π cos²x) cos(2x) + π sin(π cos²x) sin²(2x) ]

-π/2 (-2)

Answer:

Volume = ⅔πr³

Step-by-step explanation:

Given

Shape: Cone

Height = 2 * Radius

Required

An expression for the volume of the cone.

Let h and r represent the height and the radius of the cone, respectively.

So, h = 2r.

So solve this question, we simply write out the formula to calculate the volume of a cone.

Volume = ⅓πr²h

Substitute 2r for h.

Volume = ⅓πr²(2r)

Volume = ⅓πr² * 2r

Volume = ⅔πr³

Hence, the above expression represent the volume of a cone when h = 2r

The expression that represents the volume of the cone in cubic units is: ⅔πr³.

Volume of cone = ⅓πr²h

r is the radius; h is the height of the cone.

Given:

Therefore, substitute the values into the formula for the volume of a cone:

Volume of cone = ⅓π(r²)(2r)

Volume of cone = ⅔πr³

Therefore, the expression that represents the volume of the cone in cubic units is: ⅔πr³.

Answer: D.

This is tricky.

Think of the equation as an equation for a line

where in this case.      

[tex]C=5/9(f-32)[/tex]

or

[tex]C=5/9f-5/9(32)[/tex]

You can see the slope of the graph is [tex]5/9[/tex]  which means that for an increase of 1 degree Fahrenheit, the increase is [tex]5/9[/tex].

[tex]c=5/9(f)[/tex]

[tex]c=5/9(1)=5/9[/tex]

Therefore, statement I is true. This is the equivalent to saying that an increase of 1 degree Celsius is equal to an increase of [tex]9/5[/tex] Degrees Fahrenheit

[tex]c=5/9(f)[/tex]

[tex]1=5/9(f)[/tex]

[tex]f=9/5[/tex]

Since [tex]9/5=1.8[/tex] Statement 2, is true.

The only answer that has both statement I and statement II as true is D, but if you have time and want to be absolutely thorough, you can also check to see if statement III (an increase of [tex]5/9[/tex] degree Fahrenheit is equal to a temperature increase of 1 degree Celsius) is true:

[tex]c=5/9(f)[/tex]

[tex]c=5/9(5/9)[/tex]

[tex]c=25/81[/tex] which is ≠ 1)

An increase of [tex]5/9[/tex] degree Fahrenheit leads to an increase of [tex]25/81[/tex]

not 1 degree, Celsius, and so Statement III is not true.

The final answer is D.

A. an increase in the average speed a car travels and a decrease in the time it takes to reach the destination

Step-by-step explanation:

As an increase in the speed of the car decrease the time it takes to reach the destination.

Correlation is the dependence of any statistical relationship between the causal or may be two random variables. It usually indicates the type of association.

As the increase in the car speed will lead to a decrease in the distance and the time it takes to reach the destination. Hence positively correlated.

Step-by-step explanation:

theres 4 different subjects that could be in each of 4 different slots, eg, science, ss, ela, or math could be in slot one, or the same for slot two, and so on and so forth.4 x 4 = 16

The required number of ways to study 4 different subject to first four classes is 16

If we have m number of works to do and n number of peoples then the number of ways to do the work is mxn

Here we have given

Number of subjects = 4 that is math, science, art and social science

Number of classes = 4

Answer:

volume ≈ 930 cm³ (nearest cubic cm)

Step-by-step explanation:

The base of the prism which is a pentagon is regular. The apothem which is a line drawn from the center to any side of the pentagon is 4 cm. The height of the prism is 16 cm.

The volume of a prism = Bh

where

B = base area

h = height of the prism

The base of the prism can be divided into 5 congruent triangles.But the base of the triangles is unknown.

The sum of interior angle of a pentagon is 540°. That means each angle is 108° . The triangle divide the angle into 2. Making the 2 base angle as 54° each. The last angle of the triangle at the center is 72°(remember sum of angle in a triangle is 180° which is 54° + 54° + 72° = 180°) .

The angle form the center can be divided by the line of height of the triangles. The angle will then be 36°. Using tangential ratio half of the length of the base of the triangle can be known. Therefore,

tan 36° = opposite/adjacent

tan 36° = opposite/4

opposite = 4 tan 36°

The full base of the triangles = 2(4 tan 36°)

area of each triangle = 1/2 × 2(4 tan 36°) × 4 = 16 tan 36°

Base area of the prism(pentagon) = 5 × 16 tan 36° = 80 tan 36°

Volume of the prism = Bh

where

h = 16 cm

B = 80 tan 36°

volume =  80 tan 36° × 16 = 1280  tan 36° = 1280  × 0.726542528

volume = 929.974435847  cm³

volume ≈ 930 cm³ (nearest cubic cm)
