= 4 = x²

x = Answer: Length= 11 , Brteadth = 2

Step-by-step explanation: Let the breadth of the rectangle be x

length = 9 + x

area = 36 cm²

A.T.Q

36cm² = 9x*x

36 = 9x²

36/9 = 4 = x²

x = root of 4

x= 2

Therefore , breadth of rectangle is 3cm and length is 12 cm

verification:

l*b = 12*3 = 36cm²

KonstantinChe [14]

Answer:

\frac{1}{2} of the garden will be radishes.

Step-by-step explanation:

Given a rectangular garden which grows cucumbers in \frac{2}{3} of the garden.

\frac{3}{4} of the cucumber section to grow radishes.

To find:

How much of the whole garden will be radishes?

Solution:

Let the total area of the garden = x sq units

Then as per our assumption, total area to grow cucumbers:

\frac{2x}{3} sq units

Cucumber area to grow radishes = \frac{3}{4} of cucumber area

= \dfrac{3}{4}\times \dfrac{2x}{3}\\\Rightarrow \dfrac{x}{2}\ sq\ units

Fraction of whole garden to grow radishes = Area to grow radishes divided by whole area of garden

\Rightarrow \dfrac{\frac{x}{2}}{x}\\\\\Rightarrow \bold{\dfrac{1}{2}}

Therefore, \frac{1}{2} of the garden will be radishes.

David recorded his finishing time, in seconds, for each time he ran the 100 m race during one track season. What was the median
Vikentia [17]
The median is 12.1 because it is the center number in the sequence. This only applies if the numbers are in order from least to greatest, and also if there are a even number of numbers in the sequence you must take the average of the two center ones because there is no center one.

Can u plz add these together.
Rainbow [258]

Answer:

1. -3    

2. 7      

3. -2        

4. 3

Step-by-step explanation:

1.      idk

2.     3.2 move 3b over to get 3.2-3b-4.7=-3.3 move 4.7 over to get

3.2b-3b=4.7-3.3 now 3.2b-3b=.2b and 4.7-3.3=1.4  .2b/.2=b   1.4/.2=7 so b=7

3.     4.6y-y+4=y-1.2 now switch the 4 and the y to read 4.6y-2y=-4-1.2

2.6y=-5.2 divide both sides by 2.6 to get y=-2

4.      7.5c-2.5c+8=-7 move 8 to other side to get 7.5c-2.5c=-8-7

5c=-15 divide both sides by 5 getting c=3
