Kerry has a collection of 1,100 baseball cards. Of these baseball cards, 40% are dated before 1970, 25% are dated from 1970 to 2
MArishka [77]

Answer:

385 cards

Step-by-step explanation:

First, find 40% and 25% of 1100.

2/5 * 1100

2200/5 = 440 cards dated before 1970

1/4 * 1100

1100/4 = 275 cards dated between 1970 and 2000

Then add the two amounts together.

440 + 275 = 715 cards between pre-1970 and 2000

After that, subtract your new sum from 1100.

1100 - 715 = 385 cards after 2000

(Or to make it easier, just find 35% of 1100.)

PLZZZ HELP I WILL MARK BRAINIEST
charle [14.2K]

Answer: 47.5 ft^2

Step-by-step explanation: First find the area of the rectangle using the formula length*height. This is 10*4 or 40.

Then find the area of the bottom triangle using the formula (base*height)/2. This will be (3*3)/2, which simplifies to 9/2, which is 4.5.

Then find the area of the top triangle using the same formula, which will be (2*3)/2, which simplifies to 6/2, which is 3.

Add all of these together. 40+3+4.5=47.5.

Remember
(a^b)^c=a^{bc}
and
\frac{x^a}{x^b}=x^{a-b}


so

\frac{(7^2)^5}{7^{-6}}=
\frac{7^{2*5}}{7^{-6}}=
\frac{7^{10}}{7^{-6}}=
7^{10-(-6)}=
7^{10+6}=
7^{16}

the answer is D
