<h3>Answer: k = 10</h3>

======================================================

Work Shown:

Use the remote interior angle theorem.

The interior angles (4k+5) and (6k+10) add to the exterior angle 115. Note the interior angles are not adjacent to the exterior angle. This is where the "remote" aspect comes in.

So,

(4k+5) + (6k+10) = 115

10k + 15 = 115

10k = 115 - 15

10k = 100

k = 100/10

k = 10

We can stop here.

If you want to keep going, then,

4k+5 = 4*10+5 = 45

6k+10 = 6*10+10 = 70

Note how 45+70 = 115 to help confirm our answer.

5x+2y=7

y=x+1

5x+2(x+1) =7

5x +2x+2=7

7x +2 =7

7x = 5

x = 5/7

y=5/7 +1

y =12/7

(5/7, 12/7)

What's is (7x10^5) x (3x10^2)

denpristay [2]

Answer:

If you expand that, it comes out to 200000000, or in scientific notation, 2.0 × 10⁸.

Step-by-step explanation:

Starting with:

(7 × 10⁵) × (3 × 10²)

Since everything is multiplied, we can drop the brackets:

= 7 × 10⁵ × 3 × 10²

Now we can multiply seven by three, and both powers of ten:

= 20 × 10⁷

We can expand this now as

200000000

or in proper scientific notation:

2.0 × 10⁸

Need help figuring out this answer.

zmey [24]

Answer:

Volume = 184.8 cm³

Step-by-step explanation:

$Volume of pyramid=\frac{Area of the base*height}{3}$

Area = 44 cm²

Height = 12.6 cm

Put values

$Volume of pyramid=\frac{44*12.6}{3}$

= $\frac{554.4}{3}$

= 184.8cm³
