Find the minimum and maximum possible areas of a rectangle measuring 6 km by 11 km.

ExtremeBDS [4]

Assuming your numbers are rounded to the nearest km, the minimum area will be ...
(5.5 km)·(10.5 km) = 57.75 km² . . . minimum

And the maximum area will be ...
(6.5 km)·(11.5 km) = 74.75 km² . . . maximum

_____
When a number is rounded to 6 km as the nearest km, its value may actually be anywhere in the range 6 km ± 0.5 km. If you really want to get technical about it, the ranges of possible dimensions are [5.5, 6.5) km and [10.5, 11.5) km, and the range of possible areas is [57.75, 74.75) km².

PLZ HURRY IT'S URGENT!!

Answer:

OPTION C: 60%

Step-by-step explanation:

Chances of raining the next day + Chances that it will not rain = 100%

One of them should definitely be true.

So, if the chance of it raining tomorrow is 40% then there is 60% chance that it will not rain tomorrow.

This can also seen as follows:

Probability of rain tomorrow + Probability of no rain = 1

Given Probability of rain tomorrow = 40% = $\frac{40}{100} = \frac{2}{5}$

Probability of no rain tomorrow = 1 - Probability of rain tomorrow

⇒ Probability of no rain = 1 - $\frac{2}{5}$

⇒ Probability of no rain = $\frac{3}{5}$

Expressing it as percentage: $\frac{3}{5} \times 100$ = 60%.

Draw fraction rectangles on dot paper to solve the problems.

juin [17]

Answer:

1) $\frac{7}{20}$

2) $1\frac{1}{12}$

3) $\frac{7}{8}$

Step-by-step explanation:

1) Given problem,

$\frac{3}{5}-\frac{1}{4}$

LCM(5,4) = 20,

$\frac{3}{5}=\frac{3\times 4}{5\times 4}=\frac{12}{20}$

$\frac{1}{4}=\frac{1\times 5}{4\times 5}=\frac{5}{20}$

$\implies \frac{3}{5}-\frac{1}{4}=\frac{12}{20}-\frac{5}{20}=\frac{7}{20}$

2) Given problem,

$\frac{5}{6}+\frac{1}{4}$

LCM(6, 4) = 12,

$\frac{5}{6}=\frac{5\times 2}{6\times 2}=\frac{10}{12}$

$\frac{1}{4}=\frac{1\times 3}{4\times 3}=\frac{3}{12}$

$\implies \frac{5}{6}+\frac{1}{4}=\frac{10}{12}+\frac{3}{12}=\frac{13}{12}=1\frac{1}{12}$

3) ∵ Pizza ate by Manny = $\frac{1}{4}$

Pizza ate by Frank = $\farc{5}{8}$

∴ Total pizza eaten = $\frac{1}{4}+\frac{5}{8}$

LCM(4, 8) = 8,

$\frac{1}{4}=\frac{2}{8}$

Thus, total pizza eaten = $\frac{2}{8}+\frac{5}{8}=\frac{7}{8}$
