Answer:

OA = 19.58

Step-by-step explanation:

If we draw the segments OA and OC, we will have an isosceles triangle OAC.

With the property of inscribed angles and central angles that are related to the same arc of the circunference, we have:

mAOC = 2 * mABC

mAOC = 2 * 50 = 100°

As the triangle OAC is isosceles, we have that mOAC = mACO.

Knowing that the sum of internal angles of a triangle is 180°, we have:

mACO + mOAC + 100 = 180

2 * mACO  = 80

mACO = 40°

Now, using the law of sines, we have:

OA / sin(ACO) = AC / sin(AOC)

OA / 0.6428 = 30 / 0.9848

OA = 30.463 * 0.6428 = 19.58

Answer:

[tex](x+2)^2 + (y-3)^2 = 10[/tex]

Step-by-step explanation:

The standard equation for circle is

[tex](x-a)^2 + (y-b)^2 = r^2[/tex]

where point (a,b) is coordinate of center of circle and r is the radius.

______________________________________________________

Given

center of circle =((-2,3)

let r be the radius of circle

Plugging in this value of center in standard equation for circle given above we have

[tex](x-a)^2 + (y-b)^2 = r^2 \ substitute (a,b) \ with (-2,3) \\=>(x-(-2))^2 + (y-3)^2 = r^2 \\=>(x+2)^2 + (y-3)^2 = r^2 (1)[/tex]

Given that point (1,2 ) passes through circle. Hence this point will satisfy the above equation of circle.

Plugging in the point (1,2 )  in equation 1 we have

[tex]\\=>(x+2)^2 + (y-3)^2 = r^2 \\=> (1+2)^2 + (2-3)^2 = r^2\\=> 3^2 + (-1)^2 = r^2\\=> 9 + 1 = r^2\\=> 10 = r^2\\=> r^2 = 10\\[/tex]

now we have value of r^2 = 10, substituting this in equation 1 we have

Thus complete equation of circle is [tex]=>(x+2)^2 + (y-3)^2 = r^2\\=>(x+2)^2 + (y-3)^2 = 10[/tex]

Answer:

B = 42.9°

C = 87.1°

c = 7.4

Step-by-step explanation:

In this problem we are given two sides and one angle of a triangle ABC. The given values are:

a = 9

b = 8

A = 50°

In this case, there wil be only one solution, because the side opposite the given angle (side a) is longer than side b that was also given.

Calculating, let's the the law of sines.

[tex] \frac{sin A}{a} = \frac{sin B}{b} = \frac{sin C}{c} [/tex]

[tex] \frac{sin 50}{9} = \frac{sin B}{8} = \frac{sin C}{c} [/tex]

Taking for A & B, we have:

[tex] \frac{sin 50}{9} = \frac{sin B}{8} [/tex]

Let's cross multiply

(sin 50°)(8) = 9 sinB

Solving further,

[tex]sin B = \frac{8 sin 50}{9}[/tex]

[tex] sin B = \frac{6.128}{9}[/tex]

[tex] B =sin^-^1(0.68)[/tex]

B = 42.9°

Since the total angle of a triangle is 180°, to find C, we have:

C = 180 - 50 - 42.9

C = 87.1°

To find the length of c, let's also use the sine formula.

[tex]\frac{sin B}{b} = \frac{sin C}{c} [/tex]

[tex]\frac{sin 42.9}{8} = \frac{87.1}{c} [/tex]

Cross multiplying

8c = 87.1 sin 42.9

[tex] c = \frac{87.1 sin42.9}{8} [/tex]

c = 7.4

Answer:

x=12.8

Step-by-step explanation:

xy / 8 = 16 /10

xy = (8 * 16) / 10

xy = 12.8

We can have the following cases:

5 pots and each pot has 15 seeds.

3 pots and each pot has 25 seeds.

15 pots and each pot has 5 seeds.

Factors are the numbers that divides another number with no remainder.

Given,

Davi has 75 flower seeds.
Every seed is planted.

Every pot has the same number of seeds.

Find the number of pots.

We have,

Total seeds = 75

Since every seed must be planted we can have the following cases.

Case1 - 5 x 15

Here there are 5 pots and each pot has 15 seeds

Case2 - 3 x 25

Here there are 3 pots and each pot has 25 seeds.

Case3 - 15 x 5

Here there are 15 pots and each pot has 5 seeds.

Thus we can have the following answer:

5 pots and each pot has 15 seeds.

3 pots and each pot has 25 seeds.

15 pots and each pot has 5 seeds.

Answer:

The perimeter of a shape is the length of the whole shape so the perimeter of this shape would be

3 + 10 + 3 + 33 + 33 + 15 = 97 cm

Answer:

x = 10 units

Step-by-step explanation:

The formula for the area of a triangle of base x and height h is A = (1/2)(x)(h).

Here A = (1/2)(x)(8) = 40, so 8x = 80 and x = 10 units

If we look at this triangle we can see the straight line (the height). We want to use the height to figure out the side? Well divide 40 with the height (8). And now you get 5(cause 5*8 is 40. duh)

A positive and a negative become a negative. First you convery the mixed fraction into an improper fraction, then you find the common denominator of all fractions, next step according to PEMDAS, you can add and subtract in any order you would like too.

1. -7 2/3 - 5 1/2 + 8 3/4

2. -23/3 - 11/2 + 35/4

3. -92/12 - 66/12 + 105/12 The common denominator is 12.

4. -92/12 - 66/12 = -158/12 A negative and a negative is addition but just add the negative sign.

5. -158/12 + 105/12 = -53/12 =

Answer:

The probability of selecting a marble that is not red, replacing it and then one that  is white is 0.2102

Step-by-step explanation:

Number of red marbles = 7

Number of blue marbles = 12

Number of yellow marbles = 6

Number of white marbles = 9

Total marbles = 7+12+6+9=34

Probability of selecting red marble =[tex]\frac{7}{34}[/tex]

Probability of selecting no red marble = [tex]1-\frac{7}{34}=\frac{27}{34}[/tex]

Now replacing it one marble is drawn again

So, Probability of getting white marble [tex]=\frac{9}{34}[/tex]

So,the probability of selecting a marble that is not red, replacing it and then one that  is white =[tex]\frac{27}{34} \times \frac{9}{34}=0.2102[/tex]

Hence the probability of selecting a marble that is not red, replacing it and then one that  is white is 0.2102

Step-by-step explanation:

We can use foil to solve this equation:

(-3y*y)+(-3y*3)+(2*y)+(2*3) (symplify)=

-3y^2-9y+2y+6

Which equals to -3y^2-7y+6

(-3y + 2)(y + 3)

(-3y * y) + (-3y * 3) + (2 * y) + (2 * 3)

-3y^2 + -9y + 2y + 6

-3y^2 + -7y + 6

-3y^2 - 7y + 6

Merek got the correct sum, but her decomposition of 347 is incorrect.

Arithmetic is a branch of mathematics that deals with the study of numbers, their properties, and their operations. It involves the basic operations of addition, subtraction, multiplication, and division.

Here,
Merek's mistake is that she incorrectly decomposed the two-digit numbers 47 into 40 and 7 instead of 30 and 17.

To add 260 and 347, we can align the digits vertically:

 260

+ 347

-----

 607

So, the sum is 607.

Merek decomposed 347 as 300 + 40 + 7, which gives:

 260

+ 300

+  40

+   7

-----

 607

So, Merek got the correct sum, but her decomposition of 347 is incorrect. She should have decomposed 347 as 300 + 40 + 7, or as 300 + 30 + 17, instead of 300 + 40 + 7.

#SPJ3

Answer: 11,682.4 miles

Step-by-step explanation:

We can think the planet as a circle:

if we have a circle of radius R, and an arc of A degrees in the circle, the lenght of the arc is:

L = (A/180°)*3.14*R

Here we know that:

L = 4076 miles

A = 20°

Then:

4076mi = (20/180)*3.14*R = 0.3489*R

R = 4076mi/0.3489 = 11,682.4 miles
