Answer = Red portion

Firstly, find out the area of the red portion (the area around the centre).

The three figures around the centre are trapeziums, so use the trapezium area equation.

a + b / 2 x h

4.5 + 5 = 9.5

9.5 / 2 = 4.75

4.75 x 1.5 = 7.125

As there are three trapeziums, times the area by 3.

7.125 x 3 = 21.375

Area of red portion = 21.375
—
Next, find out the area of the blue portion.

As the blue portion is in the centre and the figure at the centre is an equilateral triangle, use the equilateral triangle area equation.

root 3 / 4 x a^2

root 3 / 4 x 5^2 = 10.83 (rounded to 2 d.p)
—
Area of red portion = 21.375

Area of blue portion = 10.83

This means that the red portion has a greater area.

Hope this helps :)

A biologist uses a box-shaped fish trap that measures 1/4meter by 2/3meter by 3/5meter. What is the volume of the trap in the cu
Travka [436]

To find the volume of a box-shaped fish trap, we have to multiply the three dimensions of it: 

(1/4 m)* (2/3 m)* (3/5 m)

= (1*2*3)/ (4*3*5) m^(3)

= 6/ 60 m^(3)

= 1/10 m^(3)

= 0.1 m^(3)

The volume of the box-shaped fish trap is 0.1 m^(3).

Hope this is helpful~

If a b and m∠2 = 71°, what is m∠1?
Nikolay [14]

Answer:

  71°

Step-by-step explanation:

In order to be able to solve this problem, we must assume the relation between lines "a" and "b" is that they are parallel.

If a║b, then ∠1 and ∠2 are corresponding, hence congruent.

  m∠1 = m∠2 = 71°

85.87 J or heat energy is added to a 34.8 g mass of substance the temperature rises from 21.76°C
Andru [333]

Answer:

The required specific heat is 196.94 joule per kg per °C  

Step-by-step explanation:

Given as :

The heat generated = Q = 85.87 J

Mass of substance  (m)= 34.8 gram = 0.0348 kg

Change in temperature = T2 - T1 = 34.29°C - 21.76°C = 12.53°C

Let the specific heat = S

Now we know that

Heat = Mass × specific heat × change in temperature

Or, Q = msΔt

Or, 85.87 = (0.0348 kg ) × S × 12.53°C

Or , 85.87 = 0.4360 × S

Or, S = \frac{85.87}{0.4360}

∴ S = 196.94 joule per kg per °C

Hence the required specific heat is 196.94 joule per kg per °C   Answer
