Answer 1
1) X= 5
2)X= 4



Explanation: first distribute what in the parenthesis, then combine like turns
Answer 2

Answer:

x = 5, x = 4

Step-by-step explanation:

Oh I love these!!

3x + 8 + 2x = -3(x-16)

First, distribute the -3 across the parentheses. -3(x-16)

3x + 8 + 2x = -3x + 48

Next, let's add 3x and 2x on the left side of the equation there to clean it up a bit and give us less numbers to work with. 3x + 2x

8 + 5x = -3x + 48

Let's take the opportunity to add -3x on both sides so we can get all of the algebraic expressions containing (x) on one side.

8 + 8x = 48

Subtract 8 on both sides.

8x = 40

Divide by 8 to finally isolate x!

x = 5

Second one let's go!

0.5(6x - 4) = 2x - 6x + 26

Similar to the first equation, we'll need to distribute the 0.5 across the parentheses first. 0.5(6x - 4)

3x - 2 = 2x - 6x + 26

To clean the equation up let's subtract 6x from 2x on the right side of the equation there.

3x - 2 = -4x + 26

Add 2 to both sides.

3x = -4x + 28

Isolate the algebraic expressions that hold our x variables captive. (Add -4x to both sides.)

7x = 28

Divide by 7 on both sides to isolate x.

x = 4

On a distant planet, a 20º central angle intercepts an arc of 4067 miles. What is the radius of the planet at its equator?
The radius of the planet is
miles. (Simplify your answer.)​

Answers

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

keisha estimates 259 + 372 by rounding each number to the nearest 10 what is keisha estimate of the sum

Answers

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:

If the numbers are 5, 6, 7, 8, or 9, round the number up.

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

If the number are  0, 1, 2, 3, or 4, round the number down.

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.

squared.
Find the missing side.

Answers

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)

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

a equals 9 comma


b equals 8 comma


A equals 50 degrees

Answers

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

write the equation of circle b with center B(-2,3) that passes through (1,2)

Answers

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]

Given: m∠ABC = 50°,
AC = 30
Find: OA

Answers

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
