If the side length of any equilateral triangle is increase by 7% then the area will be change in which percent? How do we do this type of maths?​

Answer:

Step-by-step explanation:

The points are in the format (x , y) so given x which is the first figure, you can find y by following the formula.

Y in the point needs to satisfy the criterion of X + 3.

Point A

x = -1

y = x + 3

= -1 + 3

y = 2

Point A satisfies the equation as y from the equation is y in the point given.

Point B

x = -1

y = x + 3

= -1 + 3

y = 2

Point B does not satisfy the equation and so is not on the line.

Point C

x = 2

y = 2 + 3

y = 5

Point C satisfies the equation as y from the equation is y in the point given.

Point D

x = -3

y = -3 + 3

y = 0

Point D satisfies the equation as y from the equation is y in the point given.

Answer:

y < 12x

....................

The shaded region in the graph of y < -2x + 10 represents the viable solution ordered pairs.

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. An inequality is used to compare two or more mathematical expressions.

We have the following inequality -

y < -2x + 10

We can write -

y < -2x + 10

Refer to the graph of the inequality attached. The shaded region represents the viable solution ordered pairs.

Therefore, the shaded region in the graph of y < -2x + 10 represents the viable solution ordered pairs.

Answer:

the coldest point would be 4 degrees.

Step-by-step explanation:

On a nuber line you would plot the point 13 and go back on the number line 9 units and you would get 4 degrees.

The temperature at its coldest point is 4° F.

Given that, one winter day, the temperature outside was 13°F. Overnight, the temperature dropped 9°F.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the temperature at its coldest point be x.

Now, x = 13 - 9

= 4° F

Therefore, the temperature at its coldest point is 4° F.

Answer:

x = 5/6

Step-by-step explanation:

Cross multiply.

18(x - 2) = 3(-7)

Divide both sides by 3.

6(x - 2) = -7

Distribute the 6.

6x - 12 = -7

Add 12 to both sides.

6x = 5

Divide both sides by 6.

x = 5/6

Answer: x = 5/6

Answer:

~7

Step-by-step explanation:

We can estimate 27 2/3 to be 28 because it is only 1/3 away from a whole number. Similarly, we can estimate 3 9/10 to be 4 because it is only 1/10 away from a whole number. Dividing the two, we get:

(27 2/3)/(3 9/10) = ~28/4 = ~7

We can estimate that the quotient of (27 2/3)/(3 9/10) will be about 7.

Answer:

4.61*10^7

Step-by-step explanation:

There are 7 places we need to show.

Answer:

We know that angels 5 and 6 are vertical angles, and that vertical angles are equal. We also know that angles 7 is equal to angle 6, in turn meaning that angle 7 is also equal to angle 5. Now we look at angle 8. We can see that angle 8 is vertical to angle 7, meaning its also equal to angle 7. We already established before that angle 7 is equal to angle 5, so if angle 8 is equal to angle 7 which is equal to angle 5. Then angle 8 is equal to angle 5.

Answer:

The acceleration is 2m/s^2

Step-by-step explanation:

Given

Variation: Direction Variation

Represent Force with F and Acceleration with A

When

[tex]F= 9N; A=3m/s^2[/tex]

Required

Find A when F =6N

The variation can be represented as:

[tex]F \alpha A[/tex]

Convert to an equation

[tex]F = kA[/tex]

Where

[tex]k = variation\ constant[/tex]

When

[tex]F= 9N; A=3m/s^2[/tex]

We have:

[tex]9N = k * 3m/s^2[/tex]

Solve or k

[tex]k = \frac{9N}{3m/s^2}[/tex]

[tex]k = 3kg[/tex]

When

[tex]F = 6N[/tex]

We have:

[tex]F = kA[/tex]

Substitute 6N for F and 3kg for k

[tex]6N = 3kg * A[/tex]

Solve for A

[tex]A = \frac{6N}{3kg}[/tex]

[tex]A = 2m/s^2[/tex]

Answer:

No

Step-by-step explanation:

Number of pieces of pepperoni available with Pamela = 112

Number of pieces of pepperoni used in one pizza = 29

Now, number of pepperoni left after using 29 in one pizza = 112 - 29 = 83

Now, Pamela makes second pizza, so again 29 pieces of pepperoni area used.

Now, number of pepperoni left after using 29 in one pizza = 83 - 29 = 54

Now, Pamela makes third pizza, so again 29 pieces of pepperoni area used.

Now, number of pepperoni left after using 29 in one pizza = 54 - 29 = 25

To make the third pizza, another 29 pepperoni are required but only 25 are available.

Therefore, there is not enough pepperoni for making 4 more pizza.

Step-by-step explanation:

The length of the line segment is 13 unit.

A line segment is a straight line with finite length, and thus, have to endpoints(points on either ends).

If the ray lies onto the considered line segment(overlapping), then it can be said belonging to the considered line segment.

(line segment has 2 fixed ends, whereas a ray has one end only, other end is not fixed)

We are given that coordinate plane shows Line A B.

We need to find the length of the line segment.

We can see that the graph has 1 unit equal to 1 cm.

Then the coordinate for Point B is (5, 13)

The length of the line segment is 13 unit.
