Answer:
20
Step-by-step explanation:
The point of contact of the tangent and the diameter of the circle is a right angle.
Thus the triangle with legs 12 and 2 × 8 = 16 is right
Using Pythagoras' identity.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
?² = 12² + 16² = 144 + 256 = 400 ( take the square root of both sides )
? =
= 20
To solve for h divide both sides by pier^2
V / pier^2 = pier^2h/pier^2
V/ pier^2 = h

Question that needs to be solved:You use 4 gallons of water on 30 plants in your garden. At that rate, how much water will it take to water 45 plants?=> 4 gallons is to 30 plants.=> 4 gallons / 30 plants = 0.13 gallons per plants.Now, it needs to water around 45 plants, let us solve how much will it need => 0.13 gallons * 45 plants = 6 gallons<span>Thus, to water 45 plants you need to have 6 gallons of water</span>
1. The total shaded area must be 2/8 = 1/4 of the whole area.2.He will need 6 tenth size strips to have an equivalent of 3/5.3.320 (40*8)
4.divide the total number of cards by the total number of persons;
total number of cards: 1,200
total number of persons: 4 (3 friends and Maria)
1,200 ÷ 4 = 300
so each person will get 300 cards.
5. so, there are six groups of 3 students each. This means that there are 18 students in total.
Each of these students sells the same about of balloons: so we can divide the total number of sold balloons; 162 by 18:
which means that each student sold 9 balloons!!
