Question 1: The pillars of a temple are cylindrically shaped. Each pillar has a circular base of radius 20 cm and height 10 cm. How much concrete mixture would be required to build 14 of such pillars? Question 2 What must be the side of an equilateral triangle so that its area should be equal to the area of an isosceles triangle with base 12m and equal sides 10m

Question 3: Find the length of the longest pole that can be placed in a room 12 m long, 8m wide and 9 m high

Question 4: Given that one cubic cm of marble weighs 25 grams and the weight of a marble block 28 cm in width and 5 cm thick is 112 kg. Calculate the length of the block

Question 5: The dimensions of an open box are 50 cm, 40 cm, and 23 cm. Its thickness is 3 cm. If 1 cubic cm of metal used in the box weighs 0.5 grams, find the weight of the box

Question 6 Two metallic right circular cones with heights 4.1 cm and 4.3 cm and base radii 2.1 cm each, are melted together and recast into a sphere. Find the diameter of the sphere

add an image, and i will answer

step-by-step explanation:

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

1

4

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

−3x

∠cbe and ∠deb are same-side interior angles.

i took the test

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
