There are 4 chocolate chip cookies and 3 oatmeal cookies in a cookie jar. If a child randomly takes 2 cookies, what is the probability that both are chocolate chip?

Answer: 1/-4

Step-by-step explanation:

Find your initial y and x points (-2y and 0x) and then find another point that is equivalent (-1y and -4x) and use m=rise/run = y2-y1/x2/x1 to get your answer of 1/-4

m<A = 112.5

m<B = 67.5

m<C = 67.5

m<D = 112.5

Consider the provided information.

The sum of all interior angle of a polygon is: (n-2)*180

Substitute n = 8.

(8-2)*180 = 1080

Thus, the measure of each angle is:

∠B and ∠C are congruent and their sum is 135°

∠B+∠C=135°

∠B=67.5°

Hence, the m angle B and m angle C is 67.5°.

The sum of all angles of a quadrilateral is 360°.

∠A+∠D+∠B+∠C=360°

∠A+∠D=360°-135°

∠A+∠D=225°

∠A and ∠D are congruent and their sum is 225°

∠A+∠D=225°

∠A=∠D=112.5°

Hence, the m angle A and m angle D is 112.5°.

The solutions for the given division are explained below:

One of the four fundamental operations of arithmetic, or how to mix numbers to create new ones, is division. Addition, subtraction, and multiplication are the other operations.

In its most basic form, the division of two natural numbers involves counting the instances in which one number is contained inside another, among other possible applications. It is not required that this number be an integer. When two natural numbers are divided with a remainder, or in the Euclidean method, the result is an integer quotient, or the number of times the second number is entirely included in the first, and a remainder, or the portion of the first number.

Answer: The distance between the points (3, 4) and (0, 0) is 5.

Step-by-step explanation: The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. This theorem can be used to find the distance between two points in a coordinate system.

To find the distance between two points in a coordinate system, you can use the following steps:

Identify the coordinates of the two points.

Calculate the difference between the x-coordinates and the y-coordinates of the two points.

Use the Pythagorean Theorem to find the distance between the two points.

For example, to find the distance between the points (3, 4) and (0, 0), you would do the following:

Identify the coordinates of the two points: (3, 4) and (0, 0).

Calculate the difference between the x-coordinates and the y-coordinates of the two points: 3 - 0 = 3 for the x-coordinates and 4 - 0 = 4 for the y-coordinates.

Use the Pythagorean Theorem to find the distance between the two points: the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides, so the distance between the points is equal to the square root of 3^2 + 4^2 = 9 + 16 = 25 = 5.

Therefore, the distance between the points (3, 4) and (0, 0) is 5.

Answer:

Step-by-step explanation:

5x + 9y = 10

4x -3y = 8  If I multiple this second equation all the way through by 3, then the y's would cancel out when I add the equations together.

12x -9y = 24  multiplied the second equation through by 3

5x + 9y = 10  Add the 2 equations together

17x         = 34  Divide both sides by 14

x = 2

Plug 2 in for x for either of the two original equations and solve for y

5x + 9y = 10

5(2) + 9y = 10

10 + 9y = 10  Subtract 10 from both sides

9y = 0  Divide both sides by 0

y = 0

b)  The mixed number seven and three fourths inches.

Step-by-step explanation:

Given:

To find the total length of the wood, sum the length of the picture and two margins:

[tex]\implies \sf Total\;length=6\frac{3}{4}+\dfrac{1}{2}+\dfrac{1}{2}[/tex]

Two halves equal 1:

[tex]\implies \sf Total\;length= 6\frac{3}{4}+1[/tex]

When adding a mixed number to a whole number, simply add the whole numbers together:

[tex]\implies \sf Total\;length= (6+1)\frac{3}{4}[/tex]

[tex]\implies \sf Total\;length= 7\frac{3}{4}[/tex]

Therefore, the total length of the wood required is:

The two ordered pairs that are solutions of the inequality are:

( 2 , 5 ) and  ( 0 , 0 )

Here we have the linear inequality:

2x - 3y < 15

To check which ordered pairs are solutions, we just need to evaluate these points on the inequality and see if it becomes true or not.

For example, with the first pair (2, 5) we will get:

2*2 - 3*5 < 15

4 - 15 < 15

-11 < 15

This is true, so (2, 5) is a solution.

The other solution is the fourth option (0, 0), so we get:

2*0 - 3*0 < 15

0 < 15

(0, 0) is also a solution.

What is the area of the triangle?

The total area bounded by a triangle's three sides is referred to as the triangle's area. In essence, it is equal to 1/2 of the base times the height, or A = 1/2 b x h. As a result, we need to know the triangular polygon's base (b) and height (h) in order to calculate its area.

From given figure we can see that WV is the height of the triangle and WU is the base.

W = (-3, 6), V = (-3, -8) and U = (0, 6).

To find the distance WV and WU by using the distance formula.

[tex]d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}[/tex]

So,

[tex]WV = \sqrt{(-3+3)^2 +(-8-6)^2} = \sqrt{(-14)^2} = 14\\ WU = \sqrt{((0+3)^2+(6-6)^2} = \sqrt{3^2} = 3[/tex]

Hence, the height is 14 units and the base is 3 units.

⇒

Area of triangle = 1/2 x base x height

                           = 1/2 x 3 x 14

Area of triangle = 21 units

Hence, the area of ΔUVW is 21 units.

Answer:

The largest possible product of two positive integers whose sum is 9 is achieved when the two integers are as far apart as possible, which occurs when one integer is the largest possible integer and the other is the smallest possible integer. The largest possible integer is the one that is closest to but less than 9, which is 8, and the smallest possible integer is 1. The product of 8 and 1 is 8, so the largest possible product of two positive integers whose sum is 9 is 8.

The angle is in 4th quadrant and the value of [tex]sin\theta[/tex] is -(4/5).

One of the most significant areas of mathematics, trigonometry has a wide range of applications. The study of the connection between the sides and angles of the right-angle triangle is essentially the focus of the field of mathematics known as "trigonometry." Therefore, employing trigonometric formulae, functions, or trigonometric identities can be helpful in determining the missing or unknown angles or sides of a right triangle. Angles in trigonometry can be expressed as either degrees or radians.

There are two other sub-branch classifications for trigonometry. The two varieties of trigonometry are as follows:

Everything is normal in Quadrant I, and Sine, Cosine, and Tangent are all positive.

However, the x direction is negative and the cosine and tangent become negative in Quadrant II.

Sine and cosine have negative values in Quadrant III.

Sine and tangent are negative in Quadrant IV.

since,

[tex]cos\theta = 3/5 (+ve)\\\ sin\theta\ is\ ( -ve)[/tex].

So the angle is in 4th Quadrant.

we know,

[tex]sin^{2}\theta + cos^{2}\theta = 1[/tex]
