Answer:

The perimeter of the garden is 126.81 feet.                                      

Step-by-step explanation:

We are given the following in the question:

Dimensions of rectangle:

Length, l = 33 feet

Width, w = 21 feet

Dimension of semicircle:

Diameter of circle, d = 33 feet

r = \dfrac{d}{2} = \dfrac{33}{2} = 16.5

Perimeter of garden =

P =\text{(Length + 2(Width)) + Perimeter of semi circle}\\P =l + 2(w) + \pi(r)\\P = 33 + 2(21) + 3.14(16.5)\\P = 126.81

Thus, the perimeter of the garden is 126.81 feet.

A city has 4 new houses for every 7 old houses. If there are 32 new houses in the city, how many old houses are there?
Maslowich

So the ration is 4:7

The total of houses is 32 new houses. What I did was I divided 32 by 4:

32/4 = 8

That means that the ratio (4:7) would be multiplied by 8 (only the :7 part):

7 * 8 = 56

There are 56 old houses (the ratio is now 32:56)

What does it mean for a product of factors to be expressed using exponents
valina [46]
Product factor is an expression in where you multiply the same value digit many times.
Exponent is the expression in where you convert product factor expression into a shorter expression
For example of product factor:
=> 9 x 9 x 9 x 9 x 9 x 9 x 9 x 9 x 9
As you can see, 9 is multiplied many times, that makes it longer.
Now, let’s make this product factor shorter using exponent.
=> since 9 is multiplied 9 times the exponent expression is:
=> 9 9 in where 9 is the base and the other 9 is called exponent.
