Answer:

It takes 500 seconds for sunlight to reach Earth.

The mass of the sun is 18.98 * 10^28.

Step-by-step explanation:

Step 1) In order to solve problem number one, you would need to divide. Remember, in math in order to get from the smaller unit to the bigger unit, you divide.

Step 2) In this case, the smaller unit is the distance from the sun to earth. The bigger unit in the other hand, is the speed of light.

Step 3) 1.5 * 10^11/300,000,000 = 500

Answer: It takes 500 seconds for sunlight to reach Earth.

Step 1) In order to solve problem number 2, convert 26,000,000 in scientific notation which is 2.6 * 10^7.

Step 2) Now, multiply the mass of the sun by the mass of the moon.

(7.3*10^22) * (2.6 * 10^7)

Step 3) Note: whenver you multiply with exponents, you must always add them, the base remains the same.

10^22 + 10^7 = 10^29

7.3 * 2.6 = 18.98

Answer: To conclude, the mass of the sun is 18.98 * 10^28.

Factor completely. Remember to look first for a common factor. If a polynomial is prime, state this.

Yakvenalex [24]

This one is prime. The sum of two squares doesn't factor.

The more interesting case is q^2-1, which factors into (q-1)(q+1).

Can someone please tell me the answer on this.

Answer: x = 31

Step-By-Step:

To Find x:

$\left(2x+20\right)+\left(x+10\right)+\left(2x-5\right)=180$ (Angle Sum Property Of Triangles)

(Remove the brackets)

$2x+20+x+10+2x-5=18$

(Group Accordingly)

$2x+x+2x+20+10-5=180$

= $5x+20+10-5=180$

= $5x\:+\:25$ $=180$

= $5x= 180 - 25$

= $5x = 155$

= $x=\frac{155}{5}$

= $31$

Therefore x = 31

So,

Angle A = x + 10 = 31 + 10 = 41

Angle B = 2*x + 20 = 2*31 + 20 = 82

Angle C = 2*x - 5 = 62 - 5 = 57

The area of a circle is 615.44 in2. What is the diameter of the circle? Use 3.14 for π.

Shalnov [3]

615.44 = (3.14)(radius)^2

radius = square-root of (615.44/3.14) 

diameter = radius x 2 

diameter = 28 inches

3.14

Plz help last one ty!!!!!!!

My apologies on answering late...

Same situation as the previous problem, but this time, all you need to do is state the degree of the angle instead of just providing the angle itself.

ΔABC ≅ ΔDEF

Now, we can see that ∠C ≅ ∠F. Using this information, we can find ∠C on the first triangle ( which is $75$ ° ).

Since ∠C ≅ ∠F,

m∠F is $75$ °.

Hope I caught your question in time!

Have a good one! If you need anymore help, let me know.
