Answer:

20%

Step-by-step explanation:

(400 x 12 x 2 - 8000)/8000 x 100 = 20%

Answer:

P = 8000

t = 2

I = p × r × t

400 = 8000 × r/100 × 2

r = 400/160 per year

r = 40/16 = 2.5 %

a bicycle has a listed price of $821.95 before tax. if the sales tax rate is 6.5%, find the total cost of the bicycle with sales
BlackZzzverrR [31]

Answer:

$875.39

Step-by-step explanation:

1) Divide the tax rate (6.500%) by 100 to get a decimal rate of 0.06500.

2) Multiply the purchase price ($821.95) by the 0.06500 to get a sales tax amount of $53.43.

3) Add the $53.43 sales tax to the $821.95 price to get a total of $875.38.

4) Round $875.38

The average weight of a newborn panda is 0.2, or 2/10 pound. Between what two integers is the weight of a newborn panda?​
sweet-ann [11.9K]

Answer:

\frac{2}{10} lies between 0 and 1.

Step-by-step explanation:

We must have in mind that given average weight of a newborn panda is a non-integer rational number, such that lies between two integer rational number. In other words, this number must satisfy the following condition:

n < \frac{a}{b} < n +1, n, a, b \in \mathbb{N}_{O}

\mathbb{N}_{O} = \mathbb{N}\,\cup\,{\{0\}}

Which is now developed mathematically to deduce a useful expression to find integers:

1) n < \frac{a}{b} < n +1 Given

2) n \cdot 1 < \frac{a}{b} < n\cdot 1 + 1 Modulative property

3) n \cdot (b\cdot b^{-1}) < a\cdot b^{-1} < n \cdot (b\cdot b^{-1}) + b\cdot b^{-1} Existence of Multiplicative inverse/Definition of division.

4) (n\cdot b)\cdot b^{-1} < a\cdot b^{-1}< [(n+1)\cdot b] \cdot b^{-1} Commutative, Associative and Distributive properties.

5) n\cdot b < a < (n+1)\cdot b Compatibility with Multiplication/Existence of Multiplicative Inverse/Modulative Property/Result.

If we know that a = 2 and b = 10, the following inequation is formed:

10\cdot n < 2 < 10\cdot (n+1)

It is quite evident to conclude that \frac{2}{10} lies between 0 and 1.

Increase 840 in the ratio 2 : 3​
Iteru [2.4K]

Ratios be 2x and 3x

\\ \rm\longmapsto 2x+3x=840

\\ \rm\longmapsto 5x=840

\\ \rm\longmapsto x=\dfrac{840}{5}

\\ \rm\longmapsto x=168

Now

  • 2x=2(168)=336
  • 3x=3(168)=508

Find MQ in parallelogram LMNQ .
Liula [17]

Answer:

MQ = 16.4

By the <u>Parallelogram Diagonals Theorem</u> , MP = <u>PQ</u>

So MQ = 2 · <u>MP</u>

<u />

Step-by-step explanation:

<u>Parallelogram Diagonals Theorem</u>

The diagonals of a parallelogram bisect each other, i.e. they divide each other into <em>two equal parts</em>.

P is the point of intersection of the diagonals.

Therefore, MP = PQ and LP = PN

If MP = 8.2, then PQ = 8.2

⇒ MQ = 8.2 + 8.2 = 16.4
