Answer and explanation:

You would multiply by 5. The reason would be because t is being divided by 5  \frac{t}{5} = 2.9 and you want to get t alone. When you multiply by 5 you will have t = 2.9 x 5

Answer:

301.6 ft³

Step-by-step explanation:

The volume (V) of a cone is calculated using the formula

V = \frac{1}{3} × area of base × perpendicular height (h)

h can be calculated by using Pythagoras' identity in the right triangle

with hypotenuse = 10 and legs 6 and h, thus

h² + 6² = 10²

h² + 36 = 100 ( subtract 36 from both sides )

h² = 64 ( take the square root of both sides )

h = \sqrt{64} = 8

Hence

V = \frac{1}{3} × π × 6² × 8

   = \frac{1}{3} × 288π = \frac{288\pi }{3} ≈ 301.6

Create a proportion using the form = to represent the following word problem.
Anna11 [10]
Answer :
x = 53.85

Step by step explanation:
If 78% of x (some numbers) is equal to 42, then we must set this as an equation to find it.

1) Rewriting 78% as a fraction and considering that when we say 78% of some number (x) we mean a product.
78% = 78/100 ➡️ 78/100x = 42

2) Then we can go on :
100 * 78/100x = 42 * 100
78x = 4200
78x/78 = 4200/78 ➡️ x = 53.85

3) Alternatively, simply dividing 42 by 0.78 (78%) would come to the same result :

42/0.78 = 53.85

ratelena [41]
If George's bike weighs 15 pounds, then we can say that because Obed's bike is 3 pounds heavier than George's, Obed's bike weighs 18 pounds. If Obed's bike weighs 18 pounds, then we can say that because Elsa's bike is twice as heavy as Obed's, Elsa's bike weighs 9 pounds.
