A florist sold 6 iris bouquets and 15 other bouquets yesterday. Based on past data, how many of the next 35 bouquets sold should

viktelen [127]

Answer:

We should expect <u>10 iris bouquet</u> will be sold out of next 35 bouquet sold.

Step-by-step explanation:

Given;

Number of iris bouquets sold yesterday = 6

Number of other bouquets sold yesterday = 15

We need to find number of iris bouquets sold out of 35 bouquets sold.

Solution:

First we will find the percent of iris bouquet sold yesterday.

Now we know that;

Total bouquet sold yesterday is equal to sum of Number of iris bouquets sold yesterday and Number of other bouquets sold yesterday.

framing in equation form we get;

Total bouquet sold yesterday = $6+15 =21$

Now we can say that;

Percent of iris bouquet sold is equal to Number of iris bouquets sold yesterday divided by Total bouquet sold yesterday and then multiplied by 100

framing in equation form we get;

Percent of iris bouquet sold = $\frac{6}{21}\times 100 = 28.57\%$

Now based on this data we need to find number of iris bouquet sold when total bouquet sold is 35.

number of iris bouquet = $\frac{28.57}{100}\times 35 = 10$

Hence we should expect <u>10 iris bouquet</u> will be sold out of next 35 bouquet sold.

A retailer purchased an electric bicycle for Rs. 35000 and sold at a profit of 16% to a customer. How much did the customer pay

motikmotik

Answer:

Rs. 45,150

Step-by-step explanation:

Given data

Cost =Rs. 35000

Profit=16%

VAT=13%

Let us find the profit to be added

=16/100*35000

=0.16*35000

=Rs. 5,600

Let us find the VAT to be added

=13/100*35000

=0.13*35000

=Rs. 4,550

Hence the cost of the bike is

=4,550+ 5,600+ 35000

=Rs. 45,150

If $-2 < x \le 3,$ then find all possible values of $5x + 1.$ Give your answer in interval notation.

kotegsom [21]

Answer: $(-9, 16]$

This is the interval from -9 to 16. Exclude -9 but include 16.

=====================================================

Work Shown:

The idea is to multiply all sides by 5, then add 1 to all sides

$-2 < x \le 3$

$5(-2) < 5x \le 5(3)$

$-10 < 5x \le 15$

$-10+1 < 5x+1 \le 15+1$

$-9 < 5x+1 \le 16$

This converts to the interval notation $(-9, 16]$

note: a curved parenthesis means "do not include this value in the solution set"; while a square bracket has us include the value. So we exclude -9 and include 16.

-5x(x-4)=-30 Could someone please help me as soon as they can :\

Flura [38]

Answer: 2 + √10 , 2 − √10

Step-by-step explanation:

-5x(x-4) = -30

divide by -5

x(x - 4) = -30

distribute the x

x^2 - 4x = 6

move the 6 to the left to have the equation equal zero

x^2 - 4x - 6 = 0

plug into the quadratic formula & solve

= 2 + √10 , 2 − √10
