Answer:

2/2

Step-by-step explanation:

Let the numerator and denominator be x/x

10/12÷x/x=5/6

10x/12x=5/6

x/x=5/6÷10/12

x/x=5/6×12/10

x/x=2/2

Therefore the numbers are 2/2

Answer:

2/2

Step-by-step explanation:

To reduce a fraction, you have to divide it by a fraction with the equivalency of 1, since anything else would change the value of the fraction. In this instance, you know that you have the fraction 10/12, and you need to reduce it to 5/6. To do this, you must divide 10/12 by a fraction that equals 1 to create 5/6. Breaking it down, you can know that 10 divided by 2 is 5 and that 12 divided by 2 is 6. 2/2 is equal to 1, so that is the answer.

Find the Value of the letter in the following questions. Give your answers to 3 s.f.
Elis [28]

Answer:

i = 75.7°

h = 48.2°

Step-by-step explanation:

==>To find i, use the sine rule for finding angles: sin(A)/a = sin(B)/b

Where,

a = 7.2cm

sin(A) = i

b = 6.5cm

sin(B) = sin(61) = 0.8746

Thus:

sin(A)/7.2 = 0.8746/6.5

Multiply both sides by 7.2

sin(A) = (0.8746*7.2)/6.5

sin(A) = 0.969 (3 s.f)

A = i° = sin^-1(0.969) = 75.7 (3 s.f)

==>To find h, use the Cosine rule for angles:

Cos(C) = (a²+b²-c²)/2ab

cos(C) = h°, a = 4, b = 4.5, c = 3.5

a² = 16

b² = 20.25

c² = 12.25

cos(C) = (16+20.25-12.25)/(2*4*4.5)

cos(C) = 24/36

cos(C) = 0.667 (3 s.f)

C = h° = cos^-1(0.667) = 48.2° (3 s.f)

YZ is the diameter, so arc YZ = 360°/2 = 180°

arc XZ = 360° - arc YZ - arc YWX = 360° - 180° - 100° = 80°

∠XYZ is an inscribed angle <span>so it is equal to half the arc XZ

</span>∠XYZ = 80°/2 = 40°

A population of 2000 starfish has a yearly per capita population growth rate of 0.012. By next year, how do you expect populatio
Alona [7]

Answer:

It will increase by 24 starfish

Step-by-step explanation:

The population is modeled by the following differential equation:

\frac{dN}{dt} = rN

Which has the following solution:

N(t) = N(0)e^{rt}

In which N(0) is the initial population and r is the growth rate.

A population of 2000 starfish has a yearly per capita population growth rate of 0.012.

This means that N(0) = 2000, r = 0.012

By next year, how do you expect population size to have changed?

This is N(1).

N(t) = N(0)e^{rt}

N(1) = 2000*e^{0.012}

N(1) = 2024

2024 - 2000 = 24

So the correct answer is:

It will increase by 24 starfish
