Do 20/10 and 22/11 because they will have 2

No because a mixed number is a whole number with a fraction and the smallest whole number is one so 1 and a fraction pulse and a fraction will equal more than 2

Find the area please

Answer:

Step-by-step explanation:

Recall that the area of a triangle is given by:

$\displaystyle A = \frac{1}{2} bh$

In this case, the base is x and the height is y. Hence:

$\displaystyle A = \frac{1}{2} xy$

We can write the following ratios:

$\displaystyle \sin \alpha = \frac{x}{12} \text{ and } \cos \alpha = \frac{y}{12}$

Solve for x and y:

$\displaystyle x = 12\sin \alpha \text{ and } y = 12\cos \alpha$

Substitute:

$\displaystyle A = \frac{1}{2}\left(12\sin \alpha\right)\left(12\cos \alpha\right)$

And simplify. Hence:

$\displaystyle A = 72\sin \alpha \cos\alpha$

In conclusion, our answer is D.

How many 3/4 foot lengths of pipe can be cut from a 7 and 1/2 foot pipe?

stiks02 [169]

Answer:

The number of pipes to be cut from total length of pipe is 10 pipes

Step-by-step explanation:

Given as :

Total length of pipe = l = 7 $\frac{1}{2}$ foot

i.e ' = $\frac{15}{2}$ foot

The length of pipe to be cut = l' = $\dfrac{3}{4}$ foot

Let The number of pipes to be cut = n pipes

According to question

The number of pipes to be cut = $\dfrac{\textrm Total length of pipe}{Length of pipe to be cut}$

i.e n = $\dfrac{l}{l'}$

Or, n = $\frac{\frac{15}{2}}{\frac{3}{4}}$

Or, n = $\frac{15\times 4}{3\times 2}$

or, n = 5 × 2

∴ n = 10 pipes

So, The number of pipes to be cut = n = 10 pipes

Hence, The number of pipes to be cut from total length of pipe is 10 pipes Answer
