I have two and one half squares and i want to divide them by one fourth. How many pieces would i have?
Nutka1998 [239]

2+½, is just 2½, now divided by 1/4.

let's first convert the mixed fraction to improper, and then divide.


\bf \stackrel{mixed}{2\frac{1}{2}}\implies \cfrac{2\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{5}{2}}
\\\\[-0.35em]
~\dotfill\\\\
\cfrac{5}{2}\div \cfrac{1}{4}\implies \cfrac{5}{2}\cdot \cfrac{4}{1}\implies \cfrac{5}{1}\cdot \cfrac{4}{2}\implies 5\cdot 2\implies 10

What equation represents the proportional relationship displayed in the table?
KATRIN_1 [288]

Answer:

y=6x

Step-by-step explanation:

Given:

The table is given as:

x   0    4       7       8

y   0    24    42     48

The relationship between 'x' and 'y' is a proportional relationship.

A proportional relationship is one in which one variable varies directly with the other by a factor of 'k' also known as constant of proportionality and k\ne 0

A proportional relationship is given as:

y=kx

Now, we plug in 'x' and 'y' values and find the value of 'k'.

Let x=4\ and\ y=24

24=k\times 4\\\\k=\frac{24}{4}=6

Therefore, the constant of proportionality is 6. Hence the complete equation is given as:

y=6x

What is the value of x to the nearest tenth
marishachu [46]

You will have to use trig to solve this:

The side you have is adjacent to the known angle

The side you are looking for is opposite the known angle

^^^This means you need to use tan:

tan(24) = \frac{x}{12}

.445222 = \frac{x}{12}

^^^input tan(24) into calculator, then multiply 12 to both sides to isolate and solve for x

5.3 ≈ x

Hope this helped!
