if the cost of a dress is multiplied by 5/8 the price then becomes $30.00 what was the original price

Alik [6]

Let's label the original price of the dress as x. We know that
$x \times \frac{5}{8} = 30$
so that means that we can find x by dividing both sides by 5/8:
$x = 30 \div \frac{5}{8}$
A simple rule for dividing fractions is 'Keep Change Flip'. You keep the first number/fraction the same, you change the ÷ to a × and you flip the second fraction. Through this rule, we can now solve the equation much more easily:
$x = 30 \times \frac{8}{5} \\ x = \frac{240}{5} \\ x = 48$
Therefore, the original price of the dress was $48

You deposit $1,600 in a bank account. The account pays 3% annual Interest compounded monthly. Find the balance after 5 years

kumpel [21]

Step-by-step explanation:

step 1. let's call the amount of money A, the initial amount P, the yearly rate r, the number of compounds per year n.

step 2. A = P(1 + r/n)^(nt)

step 3. A = 1600(1 + .03/12)^((12)(5)

step 4. A = 1600(1.0025)^(60)

step 5. A = $1858.59

What is the value of the missing angle?

Svetach [21]

Question 1.

Formula for the sum of the measures of the interior angles of an n-sided polygon:

S = 180° · (n – 2)

A hexagon has 6 edges (hence 6 interior angles), so for this question, the that sum is

S = 180° ·(6 – 2) (n = 6)

S = 180° · 4

S = 720° <——— sum of the interior angles of a hexagon.

Then, just sum all the measures of the interior angles and it must be equal to 720°:

150° + 95° + 105° + 145° + 95° + x = 720°

590° + x = 720°

x = 720° – 590°

x = 130° <——— this is the measure of the missing angle.

The second option is the correct: 130°.

—————

Question 2.

• length of the triangle's base: b = 8.7 ft;

• length of the corresponding height: h = 4.5 ft.

The area of the triangle is given by this formula. Just plug in values:

b × h
A = ————
2

(8.7 ft) × (4.5 ft)
A = —————————
2

8.7 × 4.5
A = —————— ft²
2

39.15
A = ———— ft²
2

A = 19.575 ft² <——— this is the correct answer (second option).

I hope this helps. =)
