When working in the GreenHab, it takes me 120 minutes to report 20 tomato plants. How many plants can I report in 30 minutes?

Lyrx [107]

Answer:

Numbers of Tomato plants to be reported in 30 minutes = 5 unit

Step-by-step explanation:

It is given that ,

Time taken to report 20 Tomato plants (P1) = 120 minutes (T1)

Let number of plants to be reported in 30 minutes (T2) = P2

Now , $\frac{T2}{P2} = \frac{T1}{P1}$

$\frac{30}{P2} = \frac{120}{20}$

So, P2 = 5 unit

Hence the number of plant to be reported in 30 minutes = 5 unit Answer

To allow for a models height,a designer is willing to use models that require him to change hems either up or down 2 inches.the

jenyasd209 [6]

(a)

Let's assume

the range of the lengths of the skirts is t inch

now, we are given

to change hems either up or down 2 inches

so, total change in length should be 2

so, we will have right side =2

the length of the skirts is 20 inch

this will be either greater or lesser to length of skirts

so, the difference between them will be t-20

so, we get

$|t-20|=2$

(b)

now, we can find range

firstly, we will break absolute sign

$|t-20|=-(t-20)$ for t<20

$|t-20|=(t-20)$ for t>20

because value of |t-20| must be positive

so, we get

$-(t-20)=2$

Multiply both sides by -1

$-(t-20)\times -1=2\times -1$

$(t-20)=-2$

Add both sides by 20

$(t-20)+20=-2+20$

$t=18$

$(t-20)=2$

Add both sides by 20

$(t-20)+20=2+20$

$t=22$

so, the range of the lengths of skirts is

18 in to 22 in..........Answer

(c)

Firstly, we will find difference in height of the model

5 feet 9 inches $=12\times 5+9=69in$

6 feet = $12\times 6=72in$

now, we can find difference in height

$=72-69=3in$

and we are given

difference in length of skirts =2 in

so, the difference in height is greater than the difference in length of skirts

so, the answer is NO
