Answer:

45.5

Step-by-step explanation:

To find 35% of 70, you have to use the equation...

70 x 35/100

70 x 35 = 2,450

2,450/100 = 24.5

24.5 is 35% of 70, so the item is now $24.5 less than the original price.

70 - 24.5 = 45.5

The selling price is $45.5

Elena L [17]

Answer:

Amount of time would be greater than 95 minutes

Step-by-step explanation:

We are told that machine B can pack 11 boxes per minute.

Thus, this is 11x where x represents number of minutes.

We are told that the factory revives an order of over 1100 boxes and that it had already packed 55.

Thus,the inequality equation is;

11x + 55 > 1100

Solving this;

11x > 1100 - 55

11x > 1045

x > 1045/11

x > 95 minutes

The store bought the bike at a wholesale price. The bike store marked up the wholesale cost of the bike by 60%. What was the who

marin [14]

Answer: The wholesale cost of the bike = $100

Step-by-step explanation:

Let x = wholesale cost of the bike

As per given,

Selling price = cost price + (Mark up percent) x ( cost price) (i)

Selling price of bike = $160

Mark up percent = 60% =0.60

Substitute values in (i) , we get

$160= x+0.6x\\\\\Rightarrow\ 160=1.6x\\\\\Rightarrow\ x=\dfrac{160}{1.6}\\\\\Rightarrow\ x= 100$

Hence, the wholesale cost of the bike = $100

A rather flimsy spherical balloon is designed to pop at the instant its radius has reached 3 centimeters. Assuming the balloon i

Anni [7]

Answer:

The radius is growing at the rate of 0.09 centimeter per second at the instant it pops.

Step-by-step explanation:

We are given the following information in the question:

A spherical balloon is designed to pop at the instant its radius has reached 3 centimeters.

The balloon is filled with helium at a rate of 10 cubic centimeters per second .

$\displaystyle\frac{dV}{dt} = 10~cm^3/sec.$

We have to find fast the radius is growing at the instant it pops.

Volume of spherical balloons =

$\displaystyle\frac{4}{3}\pi r^3$

Differentiating, we get,

$\displaystyle\frac{dV}{dt} = \frac{4}{3}\pi 3r^2 \displaystyle\frac{dr}{dt} = 4\pi r^2 \displaystyle\frac{dr}{dt}$

Putting the values, we get,

$10 = 4\times 3.14\times (3)^2\times \displaystyle\frac{dr}{dt}\\\\\frac{dr}{dt} = \frac{10}{4\times 3.14\times (3)^2} = 0.0884 \approx 0.09\\\\\frac{dr}{dt} = 0.09\text{ centimeter per second}$

The radius is growing at the rate of 0.09 centimeter per second at the instant it pops.
