Answer:

350 kilómetros por hora son 97,2222 metros por segundo ;)

The result of converting 350 km/h to meter per second is 97.22 m/s.

To convert from kilometers per hour (km/h) to meters per second (m/s), you need to apply the conversion factor.

The conversion factor for this conversion is 1 km/h = 0.2778 m/s.

To convert 350 km/h to m/s, multiply 350 by the conversion factor:

350 km/h×0.2778 m/s

= 97.22 m/s

Therefore, the result of converting 350 km/h to m/s is approximately 97.22 m/s.

Answer:

D

Step-by-step explanation:

Solving the inequality

- 3x + 5 > 4 ( subtract 5 from both sides )

- 3x > - 1

Divide both sides by - 3, reversing the symbol as a result of dividing by a negative value.

x < [tex]\frac{1}{3}[/tex]

The only value not less than [tex]\frac{1}{3}[/tex] is 4 → D

Step-by-step explanation:

The closest probability of a randomly selected person in the city having red hair is approximately 0.03 (or 3%).

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

A certain city has a population of around 100,000 people. In the city, there are 3,101 people with red hair.

The required probability can be calculated by dividing the number of people with red hair by the total population of the city:

= 3,101 / 100,000

= 0.03101,

It can be rounded to 0.03.

Thus, the required probability is 0.03.

Answer:

constant monomial

Step-by-step explanation:

The polynomial, 9, has 1 term and its degree is 0. Therefore, the polynomial is a constant monomial.

The given expression is a constant monomial. Therefore, option A is the correct answer.

A polynomial is a type of algebraic expression in which the exponents of all variables should be a whole number. The exponents of the variables in any polynomial have to be a non-negative integer. A polynomial comprises constants and variables, but we cannot perform division operations by a variable in polynomials.

Here given expression is 9.

A constant monomial is a term with only a constant number. There is no variable in a constant monomial.

So, 9 is a constant monomial.

The given expression is a constant monomial. Therefore, option A is the correct answer.

Answer:

Total number of employees = 86,891 employees

Step-by-step explanation:

Let

x = total number of employees

26.7% of x = 23,200

26.7/100 * x = 23,200

0.267 * x = 23,200

0.267x = 23,200

x = 23,200/0.267

x = 86,891.385767790

approximately 86,891 employees

Total number of employees = 86,891 employees

Answer:

When we have a set of N elements, the number of combinations of K elements (such that N ≤ K) from these N elements is:

[tex]C(N, K) = \frac{N!}{(N - K)!*K!}[/tex]

Then if we have 8 different types of carpet, and we want to see how many different samples of 3 types we can choose, we just need to replace N by 8, and K by 3 in the above equation:

[tex]C(8, 3) = \frac{8!}{(8 - 3)!*3!} = \frac{8!}{5!*3!} = \frac{8*7*6}{3*2} = 56[/tex]

So there are 56 different samples.

Now we can do the same, but this time we want to use 5 types of carpet, then we will have K = 5.

[tex]C(8, 5) = \frac{8!}{(8 - 5)!*5!} = \frac{8!}{3!*5!} = 56[/tex]

Again, we have 56 different samples.

Answer:

[tex]\displaystyle t=\frac{v-v_o}{a}[/tex]

Step-by-step explanation:

Equations

It's given that the velocity (v) of an object is equal to its initial velocity (vo) plus the product of its acceleration (a) and the elapsed time (t).

The equation that expresses the above relationship is

[tex]v =v_o+at[/tex]

We must write an equation that expresses time in terms of the rest of the variables given above.

Swap the equation:

[tex]v_o+at=v[/tex]

Subtract vo:

[tex]at=v-v_o[/tex]

Divide by a:

[tex]\boxed{\displaystyle t=\frac{v-v_o}{a}}[/tex]

Answer:

n= 12

Step-by-step explanation:

27=15+n

step 1. simplify

27=n+15

step 2. flip the equation n+15=27

step 3. subtract 15 from both sides

n=12

Answer:

12.

Step-by-step explanation:

We don't have the other number, so we must do the reverse operation, which is subtraction. So we have to subtract 27 from 15. 7-5 is 2, and 20-10 is 10. Add those together and you get 12.

3) x = 8  

   side(s) = 74

4) x = 10

   EF = DE = 67

   base = 31

Step-by-step explanation:

For No. 2, if you draw out two triangles with the corresponding angles, you can make it a lot easier. See the image below:

For No. 3, it is given that it's an equilateral triangle, meaning all sides and angles are congruent. So:

12x – 22 = 10x – 6 = 7x + 18

Instead of using all three at once, you can use any two. I'll be using:

12x – 22 = 10x – 6

2x = 16

x = 8

Plugging x in, we can get all the sides, because this is an equilateral triangle:

12x – 22

12(8) – 22

96 – 22

74

For No. 4, it is given that the triangle is an isosceles triangle where DE ≅ EF, so:

8x – 13 = 5x + 17

3x = 30

x = 10

Plugging in x for one of the congruent sides and the base, you can get your needed side length values:

8x – 13

8(10) – 13

80 – 13

67

x + 21

10 + 21

The measure of the angle from the given figure is 85°.

In the given figure, the measure of angle is given.

An angle is formed when two straight lines or rays meet at a common endpoint. The common point of contact is called the vertex of an angle.

In the given figure, the ray is between 90° and 80°

So, the measure of the angle is 85°

Hence, the measure of the angle from the given figure is 85°.
