Answer:

1. 8 days

2. [tex]\frac{1}{4}[/tex] pound

3. [tex]\frac{3}{28}[/tex] grams

Step-by-step explanation:

For #1, we have to divide four by [tex]\frac{1}{2}[/tex] (or 0.5), because that's the amount he gives his dog a day. For #2, we have to divide [tex]\frac{1}{2}[/tex] by two, because it is being split into two separate containers (0.5 ÷ 2 = 0.25, or [tex]\frac{1}{4}[/tex]). #3 is a bit tougher. You can first write it as [tex]\frac{3}{4}[/tex] ÷ [tex]\frac{7}{1}[/tex] (because [tex]\frac{3}{4}[/tex] of gold are being split among seven people), then rewrite this as [tex]\frac{3}{4}[/tex] · [tex]\frac{1}{7}[/tex]. Three times one is three, four times seven is 28. So the final answer is [tex]\frac{3}{28}[/tex]. Hope this helps! Feel free to ask any questions :)

Answer:

16.00 grams/mole Oxygen * (1 mole/6.022x1023 atoms) = 2.66 x 10-23 grams. Any slight differences are due to the accuracy used for the atomic.

Step-by-step explanation:

The mass of the oxygen atom is 15.9 times higher than the mass of the hydrogen atom.

The number of times a number is multiplied by itself is referred to as an exponent.

Given that, the weight of the hydrogen atom is 1.67×10⁻²⁴ g and the mass of the oxygen atom is 2.66×10⁻²³g.

To find how many times as great the mass of the oxygen atom than the mass of a hydrogen atom is, divide the mass of the oxygen atom by the mass of the hydrogen atom:

(2.66×10⁻²³)/ (1.67×10⁻²⁴)

= 1.59 × 10⁻²³⁺²⁴

= 1.59 × 10

= 15.9

Hence, the mass of the oxygen atom is 15.9 times higher than the mass of the hydrogen atom.

Identities enable us to simplify complicated expressions. They are the basic tools of trigonometry used in solving trigonometric equations, just as factoring, finding common denominators, and using special formulas are the basic tools of solving algebraic equations.

Answer:d

Step-by-step explanation:

When the bases are the same in a fraction(the base is 8 in this problem), just subtract the exponents(4-1 in this problem)and keep the base the same(8)

Answer:

∠ 1 = 105°, ∠ 2 = 75°

Step-by-step explanation:

∠ 2 and 75° are corresponding angles and are congruent, so

∠ 2 = 75°

∠ 1 and ∠ 2 are adjacent angles and sum to 180° , that is

∠ 1 + ∠ 2 = 180°

∠ 1 + 75° = 180° ( subtract 75° from both sides )

∠ 1 = 105°

The total sod needed to cover the inner circle of the roundabout is given by C = 28.27 feet

A circle is a closed figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The circumference of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle.

The equation of circle is ( x - h )² + ( y - k )² = r²

For a unit circle , the radius r = 1

x² + y² = r² be equation (1)

Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )

Given data ,

Let the city be building a new roundabout in order to correct a traffic flow issue at some of its intersections

Now , the diameter of the inner circle be d = 9 feet

So , the radius of the inner circle , r = d/2

On simplifying , we get

The radius of the inner circle r = 4.5 feet

Now , the amount of sod do they need to cover the inner circle of the roundabout = circumference of the roundabout

The circumference of the circular roundabout C = 2πr

The circumference of the circular roundabout C = 2π ( 4.5 )

The circumference of the circular roundabout C = 9π feet

The circumference of the circular roundabout C = 28.27 feet

Hence , the amount of sod for the roundabout is 28.27 feet
