Answer: A, 102

Step-by-step explanation:

Okay so just find the big square and subtract the holes

big square is 30x20 which is 600

hole #1 is 20x5 = 100

hole #2 is a triangle so you first find the base and height which are 10 and 5 respectively. Then use the triangle area formula a = 1/2bh to find that the triangle's area is 25.

Subtract the holes now

600-100-25 = 475

1 Gallon = 200 square feet covered so divide 475 by 200 to find how many gallons should be used. It's 3 gallons since you can't just buy a fraction of a gallon (Unless your being weird).

One gallon is 34, so 3 gallons is 3*34 = 102

Or in other words... A

hope you learned and can incorporate these methods for future problems :D!

A guidebook says this tower is 50m tall.Is that correct? given deegrees are 27° and 46°<br>​
inysia [295]

9514 1404 393

Answer:

   yes

Step-by-step explanation:

The tower is about 50.1 meters tall. The guidebook is correct.

__

The distance from the base of the tower to the angle vertex is ...

  d1 = h/tan(46°)

  d2 = d1 +50 = h/tan(27°)

Then the height of the tower is ...

  h/tan(46°) +50 = h/tan(27°)

  50 = h(cot(27°) - cot(46°))

  h = 50/(cot(27°) -cot(46°)) ≈ 50/(1.96261 -0.96569) ≈ 50/0.99692

  h ≈ 50.1544 . . . meters

The tower is more than 50 meters high.

7 times 8 help pls I am sorry for a wasteful
Anuta_ua [19.1K]

Answer:

56

Step-by-step explanation:

Think of it this way, 7 times 10 is 70.

7*8 is 2 less 7s, or 14 less.

70-14=56

Or, a simpler way:

7*7 is 49(perfect square)

One more seven than that is 56.

These are just two ways I quikcly remember, because for some reason I struggle with 7 and 8 mulitplication.

Hope this helps!
