Answer:

Step-by-step explanation:

The funtion is:

C(p)= 3(p)+1.07 (1)

where: 3 is the package cost, p is the number of packages and 1.07 is the taxes

the cost could be equal or less than the gift card value so:

CC \leq 15 (2)

Replace 2 en 1

15\leq 3(p) x 1.07

3(p)\leq \frac{15}{1.07}

3p [tex]\leq14.02\\\\p\leq \frac{14.02}{3} \\\\p\leq 4.67[/tex]

It´s important to aprox the quantity to the minimum value so I can buy 4 packages

The reasonable domain is for all R because any number is a possible value of the independent variable

Find the slope of this line: (15,7) (3,-2)<br><br> Help
Oliga [24]

Answer:

m=\frac{3}{4}

Step-by-step explanation:

\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(15,\:7\right),\:\left(x_2,\:y_2\right)=\left(3,\:-2\right)

m=\frac{-2-7}{3-15}

\mathrm{Refine}

m=\frac{3}{4}

Help me I need help fast it is due soon!
Arte-miy333 [17]

Answer:

400 square meters

Step-by-step explanation:

We can first solve this problem with each unit representing 1 centimeter, and then scale up at the very end. The shape that we have a parallelogram. The base is 8 cm, and the height is 2 cm. The formula for the area of a parallelogram is just bh, so the area of the parallelogram is 16 square centimeters. However, now we scale up. Since each centimeter correlates to 5 meters, each little box will correlate to 25 square meters. Therefore, 16 \cdot 25 = \boxed{400} square meters is our answer

Part A: Clancey and Ethan are starting new books. So far, Clancey has read 1/4 of his book, which has 240 total pages and Ethan
Nonamiya [84]

In order to find who has read more pages, let's find the number of pages read by each one.

The number of pages read by Clancey is:

\frac{1}{4}\cdot240=\frac{240}{4}=60

The number of pages read by Ethan is:

\frac{2}{5}\cdot170=\frac{340}{5}=68

So Ethan read more pages.

The combined number of pages in both books is 240 + 170 = 410.

The combined number of pages read is 60 + 68 = 128

So the fraction is:

\frac{128}{410}=\frac{64}{205}
