Answer:

$\dfrac{-7600}{3}$

Step-by-step explanation:

The plane is descending, so the change in height is a negative change.

rate of descent = (change in height)/time

rate of descent = (new height - old height)/time

rate of descent = (7400 ft - 15000 ft)/(3 min)

rate of descent = (-7600 ft)/(3 min)

Answer: $\dfrac{-7600}{3}$

You but a container of cat litter for 12.25 and a bag of cat food for x dial let's. The total is 19.08 witch includes 6% tax sal

shutvik [7]

Answer:

The price of cat food is 5.75 dial

Step-by-step explanation:

Given as :

The price of container of litter = 12.25 dial

The price of cat food = x dial

The total price of items = 19.08 dial including 6% sales tax

So, The total price of item excluding sales tax is A

Or, A + 6% of A = 19.08

So, 1.06 × A = 19.08

Or, A = $\frac{19.08}{1.06}$

∴ A = 18 dial

Now, The price of cat food = Total price of item excluding tax - price of container of litter

Or, The price of cat food = 18 dial - 12.25 dial

∴ The price of cat food = 5.75 dial

Hence The price of cat food is 5.75 dial Answer

6/7+3/5 simplest form

Sloan [31]

Answer:

$\huge\boxed{\dfrac{6}{7}+\dfrac{3}{5}=\dfrac{51}{35}=1\dfrac{16}{35}}$

Step-by-step explanation:

$\dfrac{6}{7}+\dfrac{3}{5}\\\\\text{Find the}\ LCD-\text{Least Common Denominator}\\\\\text{List multiples of 7}:\ 0,\ 7,\ 14,\ 21,\ 28,\ \boxed{35},\ 42,\ ...\\\text{List multiples of 5:}\ 0,\ 5,\ 10,\ 15,\ 20,\ 25,\ 30,\ \boxed{35},\ 40,\ ...\\\\LCD(7,\ 5)=\boxed{35}\\\\35=7\cdot5$

$\dfrac{6}{7}+\dfrac{3}{5}=\dfrac{(6)(5)}{(7)(5)}+\dfrac{(7)(3)}{(7)(5)}=\dfrac{30}{35}+\dfrac{21}{35}=\dfrac{30+21}{35}=\dfrac{51}{35}=\dfrac{35+16}{35}=1\dfrac{16}{35}$

A pilot flew a 400 mile flight in 2.5 hours flying into the wind. Flying the same rate and with the same wind speed the return t

eduard

Answer: 20 mph

Explanation:

Speed is a physical quantity which is equal to the ratio between the distance covered (d) and the time taken (t):

$v=\frac{d}{t}$

In the first part of the problem, the plane flew a distance of d=400 mi in a time of t=2.5 h. The speed of the plane in this case was the difference between the proper speed of the plane, v, and the speed of the wind, w, since the plane flew opposite to the wind. So we can write:

$v-w=\frac{400mi}{2.5h}=160 mph$ (1)
