Answer:

−31.5

Step-by-step explanation:

Answer:

-7.8(6) - -5.1(3)

Step-by-step explanation:

Just substitute the variables in the for values!

-46.8 - (-15.3)

• The single-digit numbers 1-9 do not have any repeated digits, so they contribute 9 numbers.

• Of double-digit numbers 10-99, the first digit can be picked from 1-9 and the second from 0-9 minus whichever one is picked for the first digit, so they contribute 9×(10 - 1) = 81 numbers.

• Of the triple-digit numbers 100-999, the first digit is picked from 1-9 and the second and third digits from 0-9, so they contribute 9×(10 - 1)×(10 - 2) = 648 numbers.

So there are 9 + 81 + 648 = 738 numbers from 1-999 without repeated digits.

Of these numbers, the ones that are even end in 0, 2, 4, 6, or 8.

• Of the single-digits, there are 4 numbers.

• Of the double-digits, the first digit can be chosen from 1-9 and the second from {0, 2, 4, 6, 8}.

•• If the first digit is odd and picked from {1, 3, 5, 7, 9}, then they contribute 5×5 = 25 numbers.

•• If the first digit is even, then they contribute 4×(5 - 1) = 16 numbers (because the first digit can't be 0).

• Of the triple-digits, the third digit is picked from {0, 2, 4, 6, 8}.

•• If both the first and second digits are odd, then they contribute 5×(5 - 1)×5 = 100 numbers.

•• If the first is odd and the second is even, then they contribute 5×5×(5 - 1) = 100 numbers.

•• If the first is even and the second is odd, then they contribute 4×5×(5 - 1) = 80 numbers.

•• If both are even, then they contribute 4×(5 - 1)×(5 - 2) = 48 numbers.

So there are 4 + (25 + 16) + (100 + 100 + 80 + 48) = 373 even numbers from 1-999 with no repeating digits.

Answer:

The Byzantine Empire, so I would say the Turks

Step-by-step explanation:

Slavs have had the greatest influence on Russian culture.

A population's collective ways of life, including its institutions, beliefs, and artistic expressions, are collectively referred to as its culture. A society's whole way of life has been referred to as its culture. It encompasses manners, dress, language, religion, rituals, and artistic standards as a result.

Russia’s unique and vibrant culture developed, as did the country itself, from a complicated interplay of native Slavic cultural material and borrowings from a wide variety of foreign cultures. In the Kievan period (c. 10th–13th century), the borrowings were primarily from Eastern Orthodox Byzantine culture.

Although many traces of the Slavic culture that existed in the territories of Kievan Rus survived beyond its Christianization (which occurred, according to The Russian Primary Chronicle, in 988), the cultural system that organized the lives of the early Slavs is far from being understood.

therefore, We can say that the greatest influence on Russian culture is because of Slavs.

Answer:

The student's estimate is 20% off.

Step-by-step explanation:

Given that a student has a container with a volume of 1.5 liters, so

As the student estimates the volume to be 1.2 liters, so

Therefore,

Percentage Error = [ |Approx Value - Exact value| ] / [ | Exact value |] × 100

                              = | 1.2 - 1.5 | / | 1.5 |  × 100

                              = [ 0.3 / 1.5 ] × 100

                              = 0.2 × 100

                              = 20%

Therefore, the student's estimate is 20% off.

Step-by-step explanation:

To simplify the expression, we just multiply the number outside the parenthesis - 8 in this problem - by both numbers inside the parenthesis.

So,

8 * 7x = 56x

8 * 2 = 16

56x + 16 is 56x + 16.

Answer:

a = -4 or 3

Step-by-step explanation:

(x, y) therefore, with (a, 12) x = a and y = 12

y = x^2 + x

12 = a^2 + a

a^2 + a - 12 = 0 (quadratic equation)

a^2 + 4a - 3a - 12 = 0

a(a+4) - 3(a+4)

(a + 4) (a - 3) = 0

a = -4, 3

Answer:

a) For sketch see attached picture.

 [tex]y=-8cos(\pi t)+10[/tex]

b) Mary will be able to enjoy the scenery for a total of 1.68 min or about 101 seconds.

Step-by-step explanation:

a) In order to find the algebraic representation of the problem, we must start by drawing a sketch of what the problem looks like (see attached picture). Next, we can analyze it to see what function better fits the situation. In this case, since the ride starts at the lowest point, then we are talking about a negative cos function. A cos function has the followng general form:

[tex] y= Acos(\omega t - \phi) + C[/tex]

where:

A= amplitude

[tex]\omega[/tex]=angular speed

t=time

[tex]\phi[/tex]= phase shift

C= vertical shift.

In this case the amplitude will be the radius of the ferris wheel, so:

A=-8

it's negative because it starts at the lowest point.

the angular speed is the angle the ride will move in a given amount of time. In this case:

[tex]\omega=\frac{\pi rad}{1 min}[/tex]

[tex]\omega=\pi rad/min[/tex]

There will be no phase shift for this problem.

the vertical shift is the height of the platform, so:

C= 2

so the algebraic expression is:

[tex]y=-8cos(\pi t)+10[/tex]

b) In order to find the total time for which she will enjoy the ride we must start by building an inequality:

[tex]-8cos(\pi t)+10>12[/tex]

and solve it for t. We can start by turning it into an equation, solve it for t and find the answers that can be found into its domain, in this case D=[0,4]

so we get:

[tex]-8cos(\pi t)+10=12[/tex]

we subtract a 10 from both sides so we get:

[tex]-8cos(\pi t)=2[/tex]

and divide 8 to both sides so we get:

[tex]cos(\pi t)=-\frac{1}{4}[/tex]

Next, we take the inverse cosine to both sides and get different answers:

[tex]\pi t = 1.823+2\pi n[/tex]

and

[tex]\pi t=4.46 + 2\pi n[/tex]

we take both equations and divide them into pi so we get:

[tex]t = 0.58+2 n[/tex]

and

[tex]t=1.42 + 2n[/tex]

so now we find the possible answers that are between 0 and 4 minutes, this is for n=0 and 1, so we get the following times:

t={0.58, 1.42, 2.58, 3.42} min

we can now build our possible intervals for which the ferris wheel is higher than 12 m so we get the following intervals:

(0, 0.58) (0.58, 1.42) (1.42, 2.58) (2.58, 3.42) and (2.58, 4)

so we pick a test value for each of the intervals and test it on our equation. If the equation gives us a number that is greater than 12, then we have a valid interval. If we get a value that is less than 12, then we just discard that interval.

for (0, 0.58) we use 0.5 and get an answer of 10. We discard this interval.

for (0.58, 1.42) we use 1 and get an answer of 18. This is a valid interval.

for (1.42, 2.58) we use a 2 and get an answer of 2. We discard this interval.

for (2.58, 3.42) we use a 3 and get an answer of 18. This is a valid interval.

and finally, for (2.58, 4) we use a 3.5 and get an answer of 10. We discard this interval

So we have two valid intervals now: (0.58, 1.42) and (1.42, 2.58). So now we can use them to find the time for which Mary will enjoy the scenery.

[tex]t_{1}=1.42min-0.58min=0.85min[/tex]

[tex]t_{2}=2.58min-1.42min=0.85min[/tex]

[tex]t_{total}=0.85min+0.85min[/tex]

[tex]t_{total}=1.68min[/tex]

so:

Mary will be able to enjoy the scenery for a total of 1.68 min or about 101 seconds.

Answer: The cumulative frequency of club members who exercise publicly for six or fewer times per week = 38

Step-by-step explanation:

The given results of the survey:

0 visits per week: 13

1-3 visits per week: 17

4-6 visits per week: 8

7 or more visits per week: 17

The  cumulative frequency of club members who exercise publicly for six or fewer times per week = Frequency for 0 visits + Frequency for 1-3 visits per week + Frequency for 4-6 visits per week

= 13+17+8

=38

Hence, the cumulative frequency of club members who exercise publicly for six or fewer times per week = 38

Answer:

The bearing of B from A is 28 degrees, approximately

The bearing of A from B is 180+28=208 degrees, approximately.

Step-by-step explanation:

The reason for approximation is from distortion of image.

See attached image to understand how the measurement has been obtained.

The measure of the bearing of city B from A is 030° and measure the bearing of city A from B is 210°.

The term bearing is used in the navigation. The bearing is the horizontal angle which is made between the direction of an object to the another object.

This angle is measure in the clockwise direction from the north direction.

For example, if 40 clockwise from the north direction is represented as 040° in a bearing angle.

The two cities in the attached image below are show. The city A is at some distance from the city B.

Let suppose the city B is from 30 degrees from the north on clockwise. Thus, to measure of the bearing of B from A will be 030°.

Now add 180 degree to this angle to get the bearing of A from B. Thus,

[tex]180+30=210^o[/tex]

Hence, the measure of the bearing of city B from A is 030° and measure the bearing of city A from B is 210°.
