Nitella [24]

Answer:

≈ 57.13cm^{2}

Step-by-step explanation:

Area of Circle:

A = π r^{2}

π (4)^{2}

π (16)

≈ 50.27cm^{2}

Area of Square:

A = l(w)

8(8) = 64 cm^{2}

Area of each corner:

64 - 50.27 = 13.73cm^{2}

13.73 ÷ 4 ≈ 3.43cm^{2}

Area of Red:

50.27 + (3.43(2)) ≈ 57.13cm^{2}

Find the common factor of the given terms 6a^3 b^2 c, 24ab^3 c^4 , 12 abc​
Pachacha [2.7K]

Answer:

Step-by-step explanation:

the way you do it is by checking the letter in every term and seeing which instance has the lowest of that letter (for now pretend the regular numbers, in this case 6 24 and 12, aren't there). Once you do that you'll see that the last term has each variable (letter) to the power of one, so that will be the common factor for the letters. Next, look at the real numbers, and you see that the lowest number each can be divided by is 6. so you have 6abc. I'm tired and I think I explained it in a confusing way, so if you still have questions search up "how to find the greatest common factor in polynomials"

Josie had some money in her bank account. She went shopping and spent $493.98. After shopping she still had %185. How much money
solong [7]

Answer:

$678.98

Step-by-step explanation:

Let the amount she had before she started spending be T. If she went shopping and spent $493.98 then the amount she would have is

= T - 493.98

Given that she has $185 left then

T - 493.98 = 185

Add 493.98  to both sides

T - 493.98 + 493.98 = 185 + 493.98

T = $678.98

She must have had $678.98 in her bank account to begin?
