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

Answer:

-3y^2-7y+6

Step-by-step explanation:

We can use foil to solve this equation:

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

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

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

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

We can use FOIL to solve.

(-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

The answer is A

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:

[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:

a c b d

a c d b

a d b c

a d c b

b a c d

b a d c

b c a d

c a b d

c a d b

a b c d

a c b d

a c d b

a d c b

b a c d

Step-by-step explanation:

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

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.

I believe what answer you have put is correct

Answer:

630

Step-by-step explanation:

260+370

This question is based on the rounding off rule. Therefore, Keisha estimate of the sum is 630.

Given:

Keisha estimates 259 + 372 by rounding each number to the nearest 10.

We need to determined the what is Keisha estimate of the sum.

According to the question,

By using the round- off rule as follows:

Example: 38 rounded to the nearest ten is 40. ...

Example: 33 rounded to the nearest ten is 30.

First we rounding off the 259,

From the first rule, 259 is round the number up.

Therefore, we get the value 260.

Now,rounding off the 372,

From the second rule, 372 is round the number down.

Therefore, we get the value 370.

Now, sum up the both numbers,

260 +370 = 630

Therefore, Keisha estimate of the sum is 630.

Answer:

11x-35

is the answer

Answer:

Step-by-step explanation:

length = 25 in

Perimeter = 86 in

2*(length + width) = 86

2*(25 + N) = 86

Divide both sides by 2

25 + N = 86/2

25 + N = 43

Subtract 25 from both sides

25 + N - 25 = 43 - 25

N = 18

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= -4 5/12

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)
