Answer:

16 x 6 divided by 2 is 48

First add the two bases together whenever you're trying to find the area of a trapezoid then multiply it by the height and multiply by it by 1/2 (which basically you divide by 2).

Kay has 28 coins which includes nickels and dimes if the total is 2.35$, how many of each coin does Kay have?

m_a_m_a [10]

Answer:9 nickels and 19 dimes.

Step-by-step explanation:

Let $n$ be the number of nickels Kay has.

Let $d$ be the number of dimes Kay has.

Value of $1$ nickel is $ $0.05$

Value of $n$ nickels is $ $0.05n$

Value of $1$ dime is $ $0.1$

Value of $d$ nickels is $ $0.1dn$

Given that Kay has a total of $28$ coins.

So, $n+d=28$ ...(i)

Given that Kay has a total value of $ $2.35$

So, $0.05n+0.1d=2.35$ ...(ii)

Using (i) and (ii),

$0.05n+0.1(28-n)=2.35\\0.05n+2.8-0.1n=2.35\\2.8-2.35=0.05n\\0.45=0.05n\\n=9$

$d=28-n=28-9=19$

The length of fencing required for a rectangular garden in terms of its width, x, if it’s length is 2 units more than 1.5 times

JulijaS [17]

Answer:

$5x+4$ units.

Step-by-step explanation:

Let x be the width of rectangle.

We have been given that the length of garden is 2 units more than 1.5 times it’s width. So length of the rectangle will be: $1.5x+2$ .

To find the length of total fencing we need to figure out perimeter of rectangle with width x and length $1.5x+2$ .

Since we know that perimeter of a rectangle is two times the sum of its length and width.

$\text{Perimeter of rectangle}=2(\text{Length+Width})$

Upon substituting length and width of garden in above formula we will get,

$\text{Perimeter of rectangular garden}=2(1.5x+2+x)$

$\text{Perimeter of rectangular garden}=2(2.5x+2)$

Upon using distributive property we will get,

$\text{Perimeter of rectangular garden}=2*2.5x+2*2$

$\text{Perimeter of rectangular garden}=5x+4$

Therefore, the length of required fencing will be $5x+4$ units.
