Answer:

1.375 *10⁷

Step-by-step explanation:

1.35 * 10⁷ gallons = 13500000 gallons

Volume of new tank = 250,000 gallons

Total volume including new tank = 13500000 + 250000

                                                       = 13750000

                                                       = 1.375 *10⁷

Answer:

C) 1.375 × 10^7

Step-by-step explanation:

1.35 × 10^7 + 250,000 = 1.375 × 10^7

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.

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°

Answer: 1 is greater 2 is less 3 is greater 4 is less

Step-by-step explanation:

Answer:

28. x > 1 (greater than)

29. x </= -1 (less than or equal to)

30. x >/= 3 (greater than or equal to)

31. x < 0 (less than)

Step-by-step explanation:

If the circle on the graph is open, it's "less than" or "greater than", but not "equal to". The open circle means that number is excluded from the answer set.

If the circle on the graph is closed, it's "less than or equal to" or "greater than or equal to"

Then the "less than" or "greater than" part depends on which way your arrow is pointing.

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

Answer:

Step-by-step explanation:

The following figure is a trapezium,

So Given,

Parallel sides of the trapezium = 17ft and 39ft

Height of the trapezium = 16ft

Therefore,

Area of the trapezium

[tex] = \frac{1}{2} \times (sum \: of \: parallel \: sides) \times height[/tex]

[tex] = \frac{1}{2} \times (17ft + 39ft) \times 16ft[/tex]

[tex] = \frac{1}{2} \times 56ft \times 16ft[/tex]

[tex] = 56ft \times 8ft[/tex]

[tex] = 448 {ft}^{2} [/tex]

Hence,

448 sq.ft is the area of the trapezium (Ans)
