A country has 32 parks that allow camping and 43 parks that have playgrounds. Of those, 10 parks both allow camping and have pla
Olenka [21]

Answer:

25

Step-by-step explanation:

Given:

32 parks allow camping

43 parks allow playgrounds

10 parks both allow camping and playgrounds

110 total parks

First, we need to add 32, 43, and 10

32 + 43 + 10 = 85

Then, we find the difference of 110 and 85

110 - 85 = 25

Since it isn't a decimal, there is no point in rounding.

vesna_86 [32]
5% of £42 = £2.10
10% of £42 = £4.20
15% of £42 = £6.30

£42 - £6.30 = £35.70

Answer:

see explanation

Step-by-step explanation:

length = \frac{60}{8} = 7.5 in

scale factor = \frac{image}{original} = \frac{8}{60} = \frac{2}{15}

length = \frac{192}{4} = 48 cm

scale factor = \frac{omage}{original} = \frac{4}{192} = \frac{1}{48}

Clara has 8 coins worth 17¢. if the coins are all dimes and pennies, how many dimes and pennies does she have?
Sliva [168]
Let x = the number of dimes
Let y =  the number of pennies.

There are 8 coins, therefore
x + y = 8        (1)

The coins are worth 17 cents, therefore
10x + y = 17     (2)

Subtract equation (1) from equation (2).
10x + y - (x + y) = 17 - 8
9x = 9
x = 1

From (1), obtain
y = 8 -x = 8 - 1 = 7

Answer: 1 dime, 7 pennies.
