Can someone help me find an equation for both of these ❤️

Answer:

α = 62°

β = 56°

gamma = 90°

Step-by-step explanation:

ΔAOB is isosceles, so m∠A = m∠ABO = 28

28 + 28 + m∠AOB = 180

m∠AOB = 180 - 28 - 28 = 124

β = 180 - 124 = 56

arcAB = 124

ΔBOC is isosceles.  α = m∠BCO = 1/2(arc AB) = 1/2(124) = 62

∠D is inscribed in a semicircle

m∠D = gamma = 90°

Answer:

12:44, or if simplified 3:11

Step-by-step explanation:

In mathematics, a ratio indicates how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six (that is, 8∶6, which is equivalent to the ratio 4∶3). Similarly, the ratio of lemons to oranges is 6∶8 (or 3∶4) and the ratio of oranges to the total amount of fruit is 8∶14 (or 4∶7).

[tex]\boxed {\boxed {\sf (1, 3) \ or \ x=1 \ and \ y=3}}}[/tex]

Step-by-step explanation:

We are given this system of equations:

[tex]4x+y=7\\4x-2y=-2[/tex]

We use elimination to solve to eliminate one of the variables, so we only have to work with one at a time. We do this by adding and subtracting the equations, and sometimes multiplying the entire equation by a number.

Notice how both equations have a 4x. This means they can easily be eliminated, without multiplying the equations by another number first. Let's subtract the 2 equations.

[tex]\ \ \ 4x+y=7\\ -(4x-2y)=-2[/tex]

The 4x will cancel because 4x-4x=0.

[tex]\ \ \ \ y=7 \\ - (-2y) = -2[/tex]

Since there are back to back negative signs, they become addition signs.

[tex]\ \ \ \ y=7 \\+2y=2[/tex]

[tex]3y=9[/tex]

We are solving for y , so we must isolate the variable. It is being multiplied by 3 and the inverse of multiplication is division. Divide both sides by 3.

[tex]3y/3=9/3\\y=3[/tex]

Now we can substitute 3 in for y in the original equations. Let's use the first one.

[tex]4x+y=7\\4x+3=7[/tex]

3 is being added to 4x. The inverse of addition is subtraction. Subtract 3 from both sides.

[tex]4x+3-3=7-3\\4x=4\\[/tex]

x is being multiplied by 4. The inverse of multiplication is division. Divide both sides by 4.

[tex]4x/4=4/4\\x=1[/tex]

x is equal to 1 and y is equal to 3. Coordinate points are written as (x, y). The solution to this system of equations is (1, 3).

The number of trees are between 150 cm and 200 cm tall is 30 trees.

It is required to find the number of trees are between 150 cm and 200 cm tall.

A histogram is a graph that shows the frequency of numerical data using rectangles. It is used to summarize discrete or continuous data that are measured on an interval scale.

Given:

The histogram graph the number of trees are arranged in vertical direction or y -axis and height of trees are arranged in horizontal direction or x -axis.

According to given question we have,

The  number of trees are between 150 cm and 200 cm tall

=30

Therefore, the number of trees are between 150 cm and 200 cm tall is 30 trees.

Step-by-step explanation:

5/6 > 4/7 so you'd have to subtract from 5/6 to even get to 4/7.

The equation for the mileage difference is 5/6 - d = 4/7.

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows:

(Mathematical Operator, Number/Variable, Expression)

Given the distance covered by Hassan = 5/6 of mile

distance covered by Eva = 4/7 of mile

5/6 = 0.833

4/7 = 0.57

since Hassan has covered more distance than Eva

so  equation is 5/6 - d = 4/7

Hence option A is correct.

y=5

Step-by-step explanation:

y= x+3...(1)

y= -x+7...(2)

(1) + (2):

y+y= (x+3) + (-x+7)

2y= (x-x) + (3+7)

2y= 10

y= 5

m∠B = 49.4°

Step-by-step explanation:

Use the law of cosines to get side c, and then the law of sines to get angle B

[tex]c^{2} = a^{2} + b^{2} - 2ab cos C\\ = 4^{2} + 5.8^{2} - 2(4)(5.8) cos 99\\ = 16 + 33.64 + 7.25855\\ = 56.25855\\c = \sqrt{56.25855} = 7.543[/tex]

sin C/c = sin B/b

sin 99/7.543 = sin B/5.8

sin B = 5.8 sin 99/7.543

        =  .75945

m∠B = arcsin .75945 = 49.4°

Answer:

4C2 * 6C2 * 5C2

Step-by-step explanation:

White balls = 4

Yellow balls = 6

Red balls = 5

In other to select a total of 6 balls, of which there must be 2 balls each of color white, yellow and red :

That means :

2 red balls from 5 red balls = 5C2

2 balls for 6 yellow balls = 6C2

2 balls from 4 white balls = 4C2

To obtain the number of possible combinations, take the product of the three combinations :

4C2 * 6C2 * 5C2

If bag contains 4 white balls, 6 yellow balls, and 5 red balls then  6 balls can be chosen if there must be 2 balls of each color in 900 ways

permutation is way of selecting and arranging things while combination is way of selecting things .

Given that  bag contains 4 white balls, 6 yellow balls, and 5 red balls

we have to select 6 balls

it's given that there must be 2 balls of each color

So here's how we can select them

2 white balls ,2 yellow balls and 2 red balls

So we have to select 2 white balls out of 4  white balls ,2 yellow balls out of 6 yellow balls and 2 red balls out of 5 red balls

so number of ways of selecting

[tex]{4 \choose 2} \times {6 \choose 2}\times {5 \choose 2}[/tex]

[tex]=6\times15\times10\\\\=900[/tex]

If bag contains 4 white balls, 6 yellow balls, and 5 red balls then  6 balls can be chosen if there must be 2 balls of each color in 900 ways
