vazorg [7]4 years ago

first convert 0.88 to degrees

so arcsin(0.88) = 61.642 degrees

Arcsin on a calculator is sin^-1

then to convert to radians divide degrees by 180 and multiply that by PI

so (61.642/180) x PI = 1.076 radians

Let SSS represent the number of sunflower plants and LLL represent the number of lily plants Ezra's water supply can water.

Fantom [35]

Answer:

Ezra can water at most approximately 8 sunflower plants with the remaining amount of water.

Step-by-step explanation:

Given the inequality function

0.7S+0.5L≤11 where S represent the number of sunflower plants and L represent the number of lily plants Ezra's water supply can water, if Ezra waters 10 lily plants, then we can calculate the maximum amount of sunflower plant that he can water with the remaining amount of water by simply substituting L = 10 into the inequality function as shown;

0.7S+0.5L≤11

0.7S+0.5(10)≤11

0.7S+5≤11

Taking 5 to the other side:

0.7S≤11-5

0.7S≤6

S≤6/0.7

S≤8.57

This shows that Ezra can water at most approximately 8 sunflower plants with the remaining amount of water.

The sides of two cubes are in the ratio 2:1. What is the ratio of their volumes ?

olasank [31]

Please mark as brainliest

Answer:

we know that, Volume of cube=a³

Let volume of 1st cube be 2x with side a and other be x with side A (according to given ratio)

Step-by-step explanation:

ATQ: 2x=a³ and, x=A³

a=³√2x and, A=x

we know that, surface area of cube is 6a²

Thus, surface area of 1st cube = 6(³√2x)²

= 6³√4x²

Surface area of 2nd cube=6(x)²=6x²

Ratio of S.A=(6³√4x²)÷(6x²)

Ratio of S.A=³√4:1

Present and contrast at leat 2 different methods of finding the volume of a cylinder with height h and radius r.

Vilka [71]

Answer:

Volume V= πr²h

Volume V= base * height

Step-by-step explanation:

Volume is the capacity of an object which is obtained by multiplying area with height. Volume of a cylinder is generally calculated by two formulas.

Volume of a cylinder V= πr²h Where r is the radius and h is the height

Volume of a cylinder V= base * height

If we analyse the two formula keeping in mind that the base of the cylinder is circular . The area of a circle is given by πr². In this first formula we can find the area of the base by applying the formula of the circular region. Volume is measured by multiplying length , breadth and height, or area with height. In both the formulas given above we find the area and then multiply with the height.
