Franklin saved money to buy art supplies

Nikolay [14]

<u>Question</u>:

Franklin saved money to buy art supplies. He used 1/5 of his savings to buy brushes. He used 1/2 of his savings to buy paint. What fraction of his savings does he have remaining?

Answer:

Franklin had $\frac{3}{10}$ of his saving left.

Step-by-step explanation:

Amount used to buy brushes = 1/5

Amount used to buy paint = 1/2

Solution:

Let the remaining amount be x

then ,

x = 1- (amount used on buying brushes + amount used for buying paints)

$x = 1- (\frac{1}{5} + \frac{1}{2})$

$x = 1- (\frac{2+5}{10})$

$x = 1- (\frac{7}{10})$

$x =\frac{10-7}{10}$

$x =\frac{3}{10}$

A 45 foot ladder is leaning against a building. If the bottom of the ladder is 27 feet from the base of the building, how tall i

taurus [48]

Answer:

The height of building to the nearest foot is h = 36 foot

Step-by-step explanation:

We have given,

Length of ladder leaning against a building, l = 45 foot

Bottom length between ladder and the building , b = 27

Now, we need to find the height of building to the nearest foot.

Let the height of building be h.

Using Pythagoras theorem,

$l^{2} = b^{2} +h^{2}$

Here, l = 45 , b = 27 and h =?

So,

$45^{2} = 27^{2} +h^{2}$

h² = 45² - 27²

h = √(45² - 27²)

h = 36

The height of building to the nearest foot is h = 36 foot

A city has 3 new houses for every 9 old houses. If there are 21 new houses in the city, how many old houses are there?

kipiarov [429]

To find your answer you would divide 21 by 3 which would be 7, once you've got 7 you would multiply it by 9 which would give you the amount of old houses that there is which would be 63.

Step-by-step explanation:

$(f - g)(x) = f(x) - g(x) \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = (2x - 4) - ( {x}^{2} + 3) \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 2x - 4 - {x}^{2} - 3 \\ \red{ \boxed{\therefore (f - g)(x) = - {x}^{2} + 2x - 7}}$
