Answer:

A tree of 60 feet casts the shadow of 100 feet, at the same time, what is the length of the shadow of a boy who is 3 feet tall ?

Solution :

Let b represents the length ( in ft ) of the shadow of the boy,

∵ Height of the boy = 3 ft,

So, the ratio of the height of boy and his shadow = \frac{3}{b}

Now, the tree of 60 ft long casts 100 ft shadow,

So, the ratio of height of tree and its shadow = \frac{60}{100}

At the same time,

\frac{3}{b}=\frac{60}{100}

Which is the required equation.

How many terms are in the arithmetic sequence 1313, 1616, 1919, ……, 7070, 7373?
Ede4ka [16]
The formula in getting the arithmetic sequence:
an = a1<span> + (n – 1)d.
</span>
We can substitute the values in order for us to know how many terms the sequence has.

an = 7373
a1 = 1313
d = 303

an = a1<span> + (n – 1)d
</span>7373 = 1313 + (n-1) 303
7373 = 1313 + 303n - 303
-303n = 1313 - 303 - 7373
303n = -1313 + 303 + 7373
303n = 6363
n = 21

So, there are 21 terms in the sequence given.

Anna11 [10]

Answer:

The answer is B. 12 cm

Step-by-step explanation:

ABC is a right triangle

AB and BC are the legs and AC is the hypotenuse.

The Pythagorean theorem a^2 + b^2 = c^2 can be manipulated to solve for a and get 12.

You are currently paying rent every year for your restaurant. You still have a contract that will last 2 more years. Starting to
Andreas93 [3]

The amount to be paid in rent after 2 years if the rent as of now is $3,000 will be; $3,213.675

The question allows that we choose the amount being paid as rent as of now.

Let the rent paid as of now be; $3,000

In essence; after the first year; the amount increases by 3.5% to become;

  • 1.035 × $3,000

  • = $3,105.

After the second year; we have;

  • 1.035 × $3,105

  • = $3,213.675

Ultimately; the amount to be paid after 2 years will be; $3,213.675.

When given the opportunity to change rent contracts;

  • A situation that will be beneficial would be a 3.5% reduction in rent per year
  • A situation that will not be beneficial would be a 7% increase in rent per year.
