Laura paddles in her canoe at a speed of 5 mph for 5 miles.

As we know that

\text{Distance=Speed*Time}\\ \\ Time=\frac{Distance}{Speed} \\

Substitute the values we get

Time=\frac{5m}{5mph}=1hr.......(i)\\

Laura hops on her windsurfer and sails for 12 miles at a speed of 6 mph.

Again using the above formula we can write

Time=\frac{12m}{6mph}=2hr.......(ii)\\

Hence from equation (i) and (ii), we can say total time of travel=1hr+2hr=3hr\\

What is the difference in the number of calories in a
Aleonysh [2.5K]

Answer:

C)265

Step-by-step explanation:

To find the median you list all the numbers in order from least to greatest. The number in the middle is the median.

In this case there are two middle number so you have to add them together then devide them by 2.

700, 740, <u>810, 900</u>, 1050, 1120.

810 + 900 = 1,710

1,710/2 = 855.

Your median is 855.

To find the difference you just subtract the two numbers.

1,120-855= 265.

Mr mehra spends 30% of his income in food 10% on charity 25% and is left with 15750 what is his salary? find his savings
nalin [4]

Answer:

Mr mehra's salary is 26250

Step-by-step explanation:

suppose,

Mr mehra's salary is x

so,

He spends in food = 30% of x

                               =(30/100) . x      [x%=x/100]

                                = 30x/100

                                =3x/10

He spends in charity =10% of x

                                    =10x/100

                                    =x/10

Money left = 15750

so,

x = 3x/10 + x/10 +  15750

⇒x - 3x/10 - x/10 = 15750

⇒(10x-3x-x) /10 = 15750

⇒6x/10 = 15750

⇒6x=157500

⇒x = 157500/6

⇒x = 26250

∴Mr mehra's salary is 26250

A, B, and C are polynomials, where:
yan [13]

Answer:

Option A. 8x² - 25x + 7.

Step-by-step explanation:

The given polynomials are

A = 3x -4

B = x + 7

C = x² + 2

Now we have to find the simplest form of A² - (B + C)

A² = (3x - 4)² = 9x² + 16 -24 x

B + C = x + 7 + x² + 2 = x² + x + 9

Now A² - (B + C) = 9x² + 16 -24x -(x² + x + 9)

= 9x² -24x + 16 - x²- x - 9

= 8x² -25x + 7

Therefore Option A. 8x² - 25x + 7 is the answer.

Q2. In a camp food was enough for 400 people for 23 days. If 60 more people joined the camp, find the number of days the food wi
victus00 [196]

Answer:

Q2)

We have food for 400 people, and it will last for 23 days.

Then we have an inverse relation, where the number of days decreases as the number of people increases, this means that we have a relationship like:

23 days = K/400 people.

Then we get:

(23 days)*(400 people) = K = 9200 days*people.

Now if we increase the number of people by 60, we get.

people = 460

Then the number of days that this will last is:

D = (9200 days*people)/460 people = 20 days.

The food will last for 20 days.

Q3) We have a proportional relationship (y = k*x) such that y = 40 when x = 200, then we get:

40 = k*200

With this, we can find the value of k

40/200 = k = 0.2

Then the proportional relationship is:

y = 0.2*x

a) We need to replace x by 15.

y = 0.2*15 = 3

y = 3

b) We need to replace y by 8.

8 = 0.2*x

8/0.2 = x = 40

x = 40

Q3) y is inversely proportional to x (y = k/x), and y = 8 when x = 30.

Then we get:

8 = k/30

Then the value of k is:

8*30 = k = 240

then the relationship is:

y = 240/x

a) we need to replace x by 4

y = 240/4 = 60

y = 60

b) we need to replace y by 360

360 = 240/x

360*x = 240

x = 240/360 = 0.666...

x = 0.666...
