Invasive weed grows at a rate of 0.0011 ft per minute a day

In the above question, it is given as

Invasive weed grows really fast and the rate of its growth is being provided as follows

The rate at which the weed is growing a day is = 1.65 ft

We need to find the, rate at which this weed is growing per minute

So, to do this, we'll find the growth in 1 min

In 24 hours growth is = 1.65 ft

Conversion factors

We know, 1 hour = 60 minutes

In 1 min growth is = \frac{1.65}{24 . 60}

Here, we have multiplied with 60 in the denominator to convert hours into minutes  

After solving the fraction we'll get

Growth in 1 min of the weed = 0.0011 ft

Hence, Invasive weed grows at a rate of 0.0011 ft per minute a day

In a certain city, 80 percent of the households have cable television and 60 percent of the households have videocassette record
alexandr1967 [171]

Answer:

60,000

Step-by-step explanation:

Let the total people in the household be 100%

If 80 percent of the households have cable television, 60 percent of the households have videocassette recorders and the number of households that have both cable television and videocassette recorders is 'x' percent. The number of households having ONLY cable television will be 80-x while households having ONLY videocassette will be 60-x.

To get x, we will have;

80-x + 60-x + x = 100

140-x = 100

x = 140-100

x = 40

This shows that 40% of the households have both cable television and videocassette.

If there are 150,000 households in the city, then the number of households that have both cable television and videocassette recorders could be 40% of 150,000

= 40/100 × 150,000

= 60,000

Number of households that owns both television and videocassette could be from 60,000.

The expression that represents the amount mother spent is 4 × 5.00 + 2.00.

This outing will cost $22.00.

Solution:

Number of members in a family = 4

Cost of one ticket = $5.00

Cost of soft drink = $2.00

Mother spent = Number of members × Cost of each ticket + Cost of soft drink

                      = 4 × 5.00 + 2.00

The expression that represents the amount mother spent is 4 × 5.00 + 2.00.

To solve this expression using PEDMAS rule.

First do multiplication.

4 × 5.00 + 2.00 = 20.00 + 2.00

Now do addition.

4 × 5.00 + 2.00 = 22.00

Hence this outing will cost $22.00.

Three cylinders have a volume of 2826 cm. Cylinder A has a height of 900 cm. Cylinder B
makkiz [27]

Answer:

the radius of each cylinder is 1 cm, 2 cm and 3 cm respectively

Step-by-step explanation:

The computation of the radius of each cylinder is shown below:

As we know that

The Volume of the cylinder = πr^2h

The radius would be

=\sqrt{  \frac{V}{\pi h} }

For cylinder A

=\sqrt{\frac{2826}{3.14\times 900} }

= 1 cm

For cylinder B

=\sqrt{\frac{2826}{3.14\times 225} }

= 2 cm

For cylinder C

=\sqrt{\frac{2826}{3.14\times 100} }

= 3 cm

Hence, the radius of each cylinder is 1 cm, 2 cm and 3 cm respectively
