Answer:

6.06 x $10^{9}$

Step-by-step explanation:

(5.25 x $10^{5}$ ) / (8.7 x $10^{-5}$ )

= (5.25 x $10^{5}$ ) x( $10^{5}$ )/ (8.7 )

= (5.25 x $10^{5 + 5}$ )/ (8.7 )

= 0.606 x $10^{10}$

= 6.06 x $10^{9}$

A telephone company in germany charges 0.12 euro per minute to call the US after a connection fee of 1.50 euro what is the total

Nana76 [90]

Answer:

Total minutes = 47 Minutes

Step-by-step explanation:

A telephone company in germany charges 0.12 euro per minute to call the US after a connection fee of 1.50 euro

Expressing the statement in mathematical terms;

Cost = 0.12x + 1.5 where x represens minutes

if the cost of the call was 7.14 euro, total minutes = ?

7.14 = 0.12x + 1.5

7.14 - 1.5 = 0.12x

5.64 = 0.12x

x = 5.64 / 0.12 = 47

Total minutes = 47 Minutes

2 2/3 of what number is 6 1/7

borishaifa [10]

$2\frac{2}{3}$ of $2\frac{17}{56}$ is $6\frac{1}{7}$

Solution:

Given $2\frac{2}{3}$ of what number is $6\frac{1}{7}$ .

Let us first convert the mixed fraction into improper fraction.

$$2\frac{2}{3}=\frac{(2\times3)+2}{3}=\frac{8}{3}$

$$6\frac{1}{7}=\frac{(6\times7)+1}{3}=\frac{43}{3}$

Now, let us take the unknown number be x.

$$2\frac{2}{3}\times x=6\frac{1}{7}$

$$\frac{8}{3}\times x=\frac{43}{7}$

Do the cross multiplication.

$$ x=\frac{43}{7}\times\frac{3}{8}$

$$ x=\frac{43\times3}{7\times8}$

$$ x=\frac{129}{56}$

Now, again change the improper fraction into mixed fraction.

$$ x=2\frac{17}{56}$

Hence $2\frac{2}{3}$ of $2\frac{17}{56}$ is $6\frac{1}{7}$ .
