12Q. Sweeti covered 2/7 of the running track by walking and rest by running and the length of the track is 630 m. Find the distance covered by running ?

Answers

Step-by-step explanation:

Given that :

Total length of the track = 630 m

Distance covered by Sweeti by walking = 2/7 of the running track

2/7 of 630 m

⇛ (2/7)×630

⇛ (2×630)/7

⇛ 1260/7

⇛ 180 m

Distance covered by walking = 180 m

Remaining distance =

Total distance - Distance covered by walking

⇛630 m - 180 m

⇛ 450 m

The total distance covered by running by Sweeti is 450 m.

Find the domain of the function

Answers

Answer:

Here you go :)

Step-by-step explanation:

Suppose Set A contains 19 elements and Set B contains 69 elements. If the total number elements
in either Set A or Set B is 75, how many elements do Sets A and B have in common?

Answers

B u A = 48

B = 45

The part of set B not included in A is B - A∩B = 45 - 7 = 38

Since B u A = 48, A must have 48-38 = 10 elements (3 exclusive of B, 7 shared with B).

------

Alternatively, the inclusion-exclusion principle may be used: A + B - (A ∩ B) = A u B

A + 45 - 7 = 48

A = 48 - 45 + 7

A = 10

NOTE that I'm using A and B to indicate the number of elements in each set, respectively.

More formally, one would write |A| and |B| to indicate the cardinality (number of elements) of the set.

Explain about the function?

An expression, rule, or law in mathematics that establishes the relationship between an independent variable and a dependent variable (the dependent variable).

An example of a rule is a function, which yields one output from a single input. The picture was obtained from Alex Federspiel. The equation y=x2 serves as an example of this. There is only one output for y for every input for x. We would say that y is a function of x since x is the input value.

A function is a relationship between a collection of inputs and a set of potential outputs, where each input is connected to exactly one output, in accordance with a technical description.

Triangle A is a scaled version of triangle B. The dimensions of triangle A are twice the dimensions of triangle B. The area of triangle B is 40.5 sq cm. What is the area of triangle A?

Answers

Step-by-step explanation:

the lengths of any line (side, height,...) in A is twice as long as in B.

now, the area of a triangle is

baseline × height / 2

so, two lines are multiplied. that means the factor 2 gets multiplied in 2 times. and that means the area increases by the factor 2×2 = 4

therefore, the area of A is

40.5 × 4 = 162 cm²

Which inequality is true when the value of R is 18? I'ma shower the answers i can choose in the picture

Answers

Answer:

See below:

Step-by-step explanation:

Hello! We can check to see if the inequality is true by replacing r with 18 as we have been told to find them in which 18 as r makes the equation true.

So our equations to test for are:

[tex]-r-3>-6\\-r+3<6\\r+3<6\\-r+3>6[/tex]

We can input 18 as r and then we see the following are correct:

1. No, as a -21 is not greater than -6

2. Yes, as -15 is less than 6.

3. No, as 21 is not greater than 6

4. No, as -15 is not greater than 6.

Possible number of committees formed is equals to 3.

What is number?

" Number is defined as the arithmetic value which represents the count of any given quantity."

According to the question,

Total number of candidates for positions = 24

Number of candidate selected for 1 committee = 7

Total possible number of committees = [tex]\frac{24}{7}[/tex]

The number of baskets with 15 pieces of fruit is 45.

Percentage is the fraction out of a number expressed as a number out of hundred. The sign used to represent percentages is %.

In order to determine the number of baskets that have 12 pieces of fruits and 15 pieces of fruits, multiply the given percentages by the total number of fruit baskets.

Number of baskets with 12 piece of fruit: 25% x 60 = 0.25 x 60 = 15

Number of baskets with 15 pieces of fruit: 75% x 60 = 0.75 x 60 = 45
