Find the equation of the line which passes through (0, 7) at a gradient of 3.

Answers

Answer:

y = 3x + 7

Step-by-step explanation:

Here, line is passing through the point (0, 7). It's x-coordinate is 0 and y-coordinate is 7

So, y-intercept (b) = 7

Gradient (or slope m) = 3

Equation of line in slope intercept form is given as:

y = mx + b

Plugging m = 3 and b = 7 in the above equation, we find:

y = 3x + 7

This is the required equation of line.

Step-by-step explanation:

The model that illustrates the relationship is 4x=10.404x=10.40

The cost of each ice cream was x=\$2.60x=$2.60

Step-by-step explanation:

Let

x----> the cost of one ice cream

we know that

The linear equation that represent this situation is

4x=10.404x=10.40

solve for x

Divide by 4 both sides

x=10.40/4x=10.40/4

If a student answers 42 out of 48
questions correctly on a quiz, what
percentage of questions did she
answer correctly?

Answers

Answer:

She answered 87.5% correctly.

Step-by-step explanation:

100÷48=2.083

2.083×42=87.5

The percentage of student answered correctly is 87.5%.

What is percentage?

A percentage, a relative value indicating hundredth parts of any quantity.

How to find the prcentage of  a number of quantity?

The following formula is a common strategy to calculate a percentage:

Determine the total amount of what you want to find a percentage.Divide the number to determine the percentage.Multiply the value by 100.

According to the given question.

Total number of questions = 48

Total number of questions which are answered correclty by a student = 42

Therefore, the percentage of question the students answered correctly is given by

[tex]Percentage = \frac{total \ correctly \ answered\ questions}{Toal\ number \ of\ questions\ } \times 100[/tex]

[tex]\implies percentage = \frac{42}{48} \times 100[/tex]

Clue is a board game in which you must deduce three details surrounding a murder. In the original game of Clue, the guilty person can be chosen from 6 people, and there are 6 different possible weapons and 9 possible rooms. At one point in the game, you have narrowed the possibilities down to 4 people, 5 weapons, and 7 rooms. What is the probability of making a random guess of the guilty person, murder weapon, and location from your narrowed-down choices, and the guess being correct? Enter a fraction or round your answer to 4 decimal places, if necessary.

Answers

Answer:  

the required probability is 0.0071  

Step-by-step explanation:

Given the data in the question;

we have narrowed the possibilities down to 4 people, 5 weapons, and 7 rooms.

so total number of combinations for the narrowed down metrics is computed as follows;

using multiplication rule:

⇒ 4 × 5 × 7 = 140 ways

Now, the probability of making a random guess from our narrowed down choices as well as getting the guess correct will be;

⇒ 1 / 140

{ assuming that the narrowed down choices have within it the correction combination }

= 0.007142 ≈ 0.0071  { four decimal place }

∴  the required probability is 0.0071

Consider a square and a regular hexagon (a six-sided figure with sides of equal length). One side of the square is 19 feet longer than a side of the hexagon, and the two figures have the same perimeter. What are the lengths of the sides of each figure?​

Answers

Answer:

square side = 57

hexagon side = 38

Step-by-step explanation:

x = side length of square

y = side length of hexagon

x = y + 19

4x = 6y

substitute for x:

4(y + 19) = 6y

4y + 76 = 6y

subtract 4y from each side of the equation:

2y = 76

divide both sides by 2:

y = 38

x = 57

Answer:

Hi there,

Make the side of the hexagon = x

Side of square = x + 12

Both figures have the same perimeters.

4(x + 14) = 6x

4x + 56 = 6x

Collect like terms:

6x - 4x = 56

2x = 56

x = 28

Length of hexagon side = 28 feet

Length of square side = 42 feet

The relative anonymity of an individuals identity in a city makes it difficult for rules of purity and pollution to be observed and enforced in the public sphere.Fewer activities are then mediated by an individuals caste identity. And urbanisation will continue to increase. By 2030, 40 per cent of Indians are predicted to live in urban areas.The urban middle class, once a preserve of the upper castes, has become more diverse with gradual entry of backward castes and Dalits.The marriage market reflects this change. In 1970, only 1.5 per cent of matrimonial ads published in the national dailies belonged to backward castes and Dalits. This number had increased to 10 per cent by 2010.In cities, the search for partners differs from that in villages.
