Solving $(-\frac{3}{5})(17\frac{5}{8})$ we get $-10\frac{23}{40}$

Step-by-step explanation:

Solve: $(-\frac{3}{5})(17\frac{5}{8})$

We need to multiply the two terms.

Solving:

$(-\frac{3}{5})(17\frac{5}{8})$

Converting\,\,mixed\,\,fraction\,\,into\,\,improper\,\,fraction:

$(-\frac{3}{5})(\frac{141}{8})$

Now multiplying numerator with numerator and denominator with denominator:

$-\frac{423}{40} \\-10\frac{23}{40}$

So, Solving $(-\frac{3}{5})(17\frac{5}{8})$ we get $-10\frac{23}{40}$

Question 1 Answer:

Aunt 1 and Grandma 1 would fill gift bags.

Mom and Aunt 2 would make centerpieces.

You and Grandma 2 would blow up balloons.

Since you are pairing up to complete the tasks, these pairs each have the shortest times in their respective categories and therefore are the most logical pairing to complete tasks.

Question 2 Answer:

We use algebra and our previous pairings to determine the length of each task.

Gifts Bags --> 6/7 hours

x = time together

$\frac{1}{x}$ = rate of completion

Aunt 1 = $\frac{1}{1.5}$ Grandma 1 = $\frac{1}{2}$

$\frac{2}{3} +\frac{1}{2} = \frac{1}{x}$

$\frac{7}{6} = \frac{1}{x}$

$x = \frac{6}{7}$

Centerpieces --> 7/4 hours

x = time together $\frac{1}{x}$ = rate of completion

Mom = $\frac{1}{3.5}$ Aunt 2 = $\frac{1}{3.5}$

$\frac{2}{7} + \frac{2}{7} = \frac{1}{x}$

$\frac{4}{7} = \frac{1}{x}$

$x = \frac{7}{4}$

Balloons --> 15/16 hours

x = time together $\frac{1}{x}$ = rate of completion

You = $\frac{1}{1.5}$ Grandma 2 = $\frac{1}{2.5}$

$\frac{2}{3} + \frac{2}{5} = \frac{1}{x}$

$\frac{16}{15} = \frac{1}{x}$

$x = \frac{15}{16}$

Shortest amount of time to complete all tasks is:

$\frac{6}{7} + \frac{7}{4} + \frac{15}{16} = \frac{397}{112}$ ≈ 3.54 hours

Converting hours to hours and minutes --> 3 hours 32 minutes

Therefore they must arrive by 5:28pm to complete the tasks in time to leave at 9:00pm.

Answer: I wow I don't know about the whole page but (Question 2 ) 24 multiplied by b equals number of mangoes in b boxes

Step-by-step explanation: I hope this makes sense.

b can be replaced with any number you can create a number sentence by plugging in 4 for example 24 * 4 = 96 so there is a total of 96 mangoes if b= 4

Function a(e) represents the surface area of a cube in terms of its edge length, e, and the difference quotient is 12e 6h. what

hram777 [196]

48 square inches per inch is the average rate of change in surface area.

What is an area in math?

The area is the region bounded by the shape of an object. The space covered by the figure or any two-dimensional geometric shape, in a plane, is the area of the shape.

The surface area of a cube of side length e is:

A(e) = 6 *e².

The rate of change is:

A'(e) = 2 * 6 * e

The average rate of change between 3 in and 5 in is:

r = (A(5in) + A(3in))/2 = (2*6*5in + 2*6*3in)/2 = 48in

Now, the options are given in:

"squere inches per inch"

This is written as:

in^2/in = in.

Then we can write our above rate as:

r = 48in = 48in^2/in = 48 square inches per inch.
