nadezda [96]

X=number of hours you read
y=number of pages

y=30x+70
number of pages after 3 hours:
y=30(3)+70
y=90+70
y=160

therefore, 160 pages after 3 hours

Elza [17]

9514 1404 393

Answer:

195 ft

Step-by-step explanation:

The relationship between the horizontal distance, angle, and vertical height is given by ...

Tan = Opposite/Adjacent

Referring to the attached diagram, we have ...

tan(16°) = BT/MB

tan(25°) = BK/MB

Solving for BT and BK, we can describe their difference as ...

BT = MB·tan(16°)

BK = MB·tan(25°)

BK -BT = 35 = MB(tan(25°) -tan(16°))

Dividing by the coefficient of MB gives ...

MB = 35/(tan(25°) -tan(16°)) = 35/0.179562

MB = 195 . . . feet

Marcos is standing 195 feet from the base of the tree.

A glass container can hold 216a^3 cubic cm of water. inside the glass container is a metallic cube with a volume of 64b^3 cubic

xz_007 [3.2K]

Answer:

$16(3a-2b)(4a^2+3ab+2b)$

Step-by-step explanation:

We will be able to fill the glass up to the amount of water possible to hold in the glass, minus the amount in the cube. This means it will be able to hold $216a^3-64b^3=(6a)^3-(4b)^3$ cubic cm of water.

Using the difference of cubes formula(you can prove this by expanding back out again), we get that $(6a^3)-(4b)^3=(6a-4b)((6a)^2+(6a)(4b)+(4b)^2)=(6a-4b)(36a^2+24ab+16b)=8(6a-4b)(4a^2+3ab+2b)=16(3a-2b)(4a^2+3ab+2b)$

Therefore, the answer is $\boxed{16(3a-2b)(4a^2+3ab+2b)}$ cubic centimeters and we're done!
