You want one non-zero digit in front of the decimal. Count how many times the decimal must move to be behind the first non-zero digit. This is the power on the ten. If it moves to the left, the power is negative. If you must move it to the right it is positive.

I counted 7 moves to get to behind the 6.

The ratio of petunias to geraniums in the greenhouse was 15 to 2. Combined there was 1020. How many geraniums were in the greenh
Mrac [35]

in short, we simply split the total amount by the given ratio, so we'll split or divide 1020 by (15 + 2) and then distribute accordingly.

\bf \cfrac{petunias}{geraniums}\qquad 15:2\qquad \cfrac{15}{2}~\hspace{7em}\cfrac{15\cdot \frac{1020}{15+2}}{2\cdot \frac{1020}{15+2}}\implies \cfrac{15\cdot \frac{1020}{17}}{2\cdot \frac{1020}{17}} \\\\\\ \cfrac{15\cdot 60}{2\cdot 60}\implies \cfrac{900}{120}\implies \stackrel{petunias}{900}~~:~~\stackrel{geraniums}{120}

Put the following equation of a line into slope-intercept form, simplifying all fractions. 12x+9y=18
stira [4]

Answer:

y = -4/3x + 2

Step-by-step explanation:

Slope intercept form is y = mx + b.

Rearrange the equation into slope intercept form by isolating y:

12x + 9y = 18

9y = -12x + 18

Divide each side by 9:

y = -4/3x + 2

So, the equation is y = -4/3x + 2

The monthly salary of mr nadir is $6723.50 and his monthly expenditure is $3854.75. how much does he save in one year.
levacccp [35]

The one year savings of Mr. Nadir is $. 34, 425

Given:

Mr. Nadir Monthly salary = $6723.50

His monthly Expenditure = $3854.75

Now we have to find the savings amount of each month.

For that, first we have to calculate the remaining amount he has after spending the expenditure.

To calculate the remaining amount we have to subtract the expenditure from the total amount that's is his salary.

So,

Remaining amount = Salary - Expenditure

Remaining amount = 6723.50 - 3854.75

=> 2868.75

So, for one year he must save the amount

=> 2868.75 x 12 = 34425
