Solve for a.<br> 5 + 14a = 9a - 5

stira [4]

Since you are solving for a, you want to have a on one side of the equation and the other terms on another side of the equation. It would be easiest to have all the terms with a on the left side of the equation, so that is what we will do.

Subtract 9a from both sides to get a on the left side of the equation.

5 + 5a = -5

Subtract 5 from both sides of the equation to isolate the term with a.

5a = -10

Divide both sides of the equation by 5 to solve for a.

a = -2

The K-team can paint a whole house in 60 minutes (super fast!!!). How much of a house can the team paint in 1 minute? The K-team can paint 1/60 of a house per minute.

The C-team can paint a whole hose in 80 minutes. How much of a house can the team paint in 1 minute? The C-team can paint 1/80 of a house per minute.

Suppose both teams paint for the same amount of time -- call the time t (minutes).

Combine the work they do to paint 1 whole house:

$\frac{1}{60}t+\frac{1}{80}t=1$

Multiply all the terms by the Least Common Denominator, LCD = 240.

$240(\frac{1}{60})t+240(\frac{1}{80})t=240$

Now, can you finish it? By the way, the answer is not a whole number! Hint: it will be between 30 and 40 minutes.

I WILL GIVE 20 POINTS TO THOSE WHO ANSWER THIS QUESTION RIGHT NOOOO SCAMS AND EXPLAIN WHY THAT IS THE ANSWER. What is the volume

Law Incorporation [45]

Step-by-step explanation:

the volume of any pyramid is

base area × height / 3

so, since we know the base area (a square with 23 mm side length), the only trick we need to do is to get the inner height (straight up in the middle from the base area to the top of the pyramid).

because this is a regular pyramid (the top of the pyramid is right above the middle of the base area), we can use Pythagoras for right-angled triangles

c² = a² + b²

with c being the Hypotenuse (the baseline of the triangle opposite of the 90° angle) and in our case the outer height along a side area triangle (24 mm).

the legs of that right-angled triangle are half of a base area side length (remember, the top of the pyramid is right over the middle of the base area square) and the inner height to the top.

so, we have

24² = 12.5² + height²

height² = 24² - 12.5² = 576 - 156.25 = 419.75

height = 20.48780125... mm

so, the volume of the pyramid is then

23² × 20.48780125... / 3 = 3,612.682287... mm³ ≈

≈ 3,612.7 mm³
