90-20 leaves 70 for surfing. since surfing is 5 per hour, 70/5=14 hours she can surf.

To solve this, we’ll use an equation!
20 (basic cost) + 5x ($5 per hour) = <$90.

We want the cost to stay under or at $90!

Let’s first begin by simplifying it. We can get rid of the 20 in the equation by subtracting it from both sides, so we’re just left with 5x = 70. Now, it’s a simple matter of division!

Divide 70 by 5 to simplify even more and you’ll discover that you’re left with x = 14. This means that Gina can hang out there for 14 hours before running out of money!

If a fish swims 7/8 of the depth of a 32-foot deep lake, how many feet down did the fish swim?
Arlecino [84]
8/8 would be 32 so 7/8 would be 28 because 8 x 4 = 32 which would make each eight equal four.

Greta is trying to determine the portion of green candies in various bags of green and yellow candies. Using the information bel
IrinaK [193]

Answer: a) \dfrac{1}{3} b) \dfrac{71}{100} c) \dfrac{5}{9}

Step-by-step explanation:

Since we have given that

There are green and yellow candies in each bag.

Bag A: Two thirds of the candies are yellow. What portion of the candies is green?

Part of yellow candies in bag A = \dfrac{2}{3}

Part of green candies in bag A would be

1-\dfrac{2}{3}\\\\=\dfrac{3-2}{3}\\\\=\dfrac{1}{3}

Bag B: 29 % of the candies are yellow. What portion of the candies is green?

Percentage of candies are yellow = 29%

Portion of candies are green is given by

1-\dfrac{29}{100}\\\\=1-0.29\\\\=0.71\\\\=\dfrac{71}{100}

Bag C: 4 out of every 9 candies are yellow. What portion of the candies is green?

Portion of yellow candies = \dfrac{4}{9}

Portion of green candies would be

1-\dfrac{4}{9}\\\\=\dfrac{9-4}{9}\\\\=\dfrac{5}{9}

Hence, a) \dfrac{1}{3} b) \dfrac{71}{100} c) \dfrac{5}{9}

olga2289 [7]

Answer:

25% of 200 is 50

Step-by-step explanation

40% of a number is 80

.40 * n = 80

Divide each side by .4

.40 n/.4 = 80/.4

n = 200

The number is 200
