Amy can paint a room in 12 hours. Alicia can paint the same room in 16 hours. How long does it take for both Amy and Alicia to p
Simora [160]
Well 12 is 3\4 of 16 so honestly it would take the 8 hours working together.

As far as formula if I had to guess it would look like.. 12Amy(Ay)- 16Alicia(Aa) = 4 hours minus 4 from Amy would be 8hours.

in fraction form might make more sense. 3\4 - 4\4 = 1/4 minus that from Amy and she'll finish together with Alicia 4 hours quicker being 8hours.

PLEASE ONLY ANSWER IF YOU KNOW IT!! DO NOT ANSWER FOR POINTS OR I WILL REPORT YOU!!!

It should be 12cm because

h=height
a=area
b=base

h=a/b we have base 15cm and height 8cm

8cm=a/15cm
8cm*15cm=a
120cm^2=a

we then use the area to find the height with base 10

h=a/b
h=120cm^2/10cm

h=12cm

Can someone please help me with these 2 problems? I’m confused

Answer:

7) \dfrac{25c^2}{d^4}

8) 4w^6r

Step-by-step explanation:

You must use the laws of exponents.

7)

(\dfrac{5c}{d^2})^2 =

When you raise a fraction to an exponent, raise the numerator and the denominator to that exponent.

= \dfrac{(5c)^2}{(d^2)^2}

When you raise a product to an exponent, raise each factor to that exponent.

When you raise an exponent to an exponent, multiply the exponents.

= \dfrac{5^2c^2}{d^4}

= \dfrac{25c^2}{d^4}

8)

\dfrac{-16w^7r^2}{-4wr} =

To divide powers with the same base, subtract the exponents. Remember that a plain variable, such as w is the same as w^1.

=\dfrac{-16}{-4}w^{7-1}r^{2-1}

= 4w^6r
