Step-by-step explanation:

hope this helps :)

Answer:

30.4/15 = 2 2/75

Step-by-step explanation:

Step 1 - Find Whole Number

Calculate out how many times the denominator goes into the numerator. To do that, divide 30.4 by 15 and keep only what is to the left of the decimal point:

30.4 / 15 = 2.026666667 = 2

Step 2 - Find New Numerator

Multiply the answer from Step 1 by the denominator and deduct that from the original numerator.

30.4- (15 x 2) = 0.4

Step 3 - Get Solution

Keep the original denominator and use the answers from Step 1 and Step 2 to get the answer. 30.4/15 as a mixed number is:

2 0.4/15 = 2 2/75

  c.  $76.17 billion

Step-by-step explanation:

The relations between imports, exports, and tariffs can be described by ...

  0.06E +0.21I = $18.9603 . . . . . . total tariff revenue

  I -E = 26.76 . . . . . . . . . . . . . . . . trade deficit

Solving the second equation for E gives ...

  E = I -26.76

Substituting into the first equation yields ...

  0.06(I -26.76) +0.21I = 18.9603

  0.27I = 18.9603 +1.6056 = 20.5659 . . . . add 1.6056 to both sides

  I = 10.5659/0.27 = 76.17

Romania's imports are worth about $76.17 billion.

Additional comment

The exports are worth about $76.17 -26.76 = $49.41 billion.

a. The number of rolls of wrapping paper it will take to cover the new box is 2¹/₄ rolls

b. The volume of the new rectangular box is 270 in³

Since the small box is a rectangular prism, its surface area, A = 2(lb + lh + bh) where

Now, when the dimensions are tripled, its new area is A' = 2(LB + LH + BH) where

So, A' = 2(LB + LH + BH)

= 2((3l)(3b) + (3l)(3h) + (3b)(3h))

= 2(3)(3)(lb + lh + bh)

= 18A

The number of rolls of wrapping paper it will take to cover the new box is 2¹/₄ rolls

Now, since we require 1/8 of a roll of wrapping paper to initially cover all 6 sides of the small box with dimensions, l,b and h. Then the number of rolls we require to cover the box when its dimensions are tripled are (since the area is proportional to the number of rolls)

N = 18 × 1/8

= 18/8

= 9/4

= 2¹/₄ rolls

The number of rolls of wrapping paper it will take to cover the new box is 2¹/₄ rolls

The volume of the new rectangular box is 270 in³

The volume of the rectangular box V = lbh where

When the dimensions are tripled, V' = LBH where

So, V' = LBH

= (3l)(3b)(3h)

= 27lbh

= 27V

Now since the initial volume of the rectangular box, V = 10 in³

V' = 27V

V' = 27 × 10 in³

V' = 270 in³

So, the volume of the new rectangular box is 270 in³

2/5 * 30 is 12

12+30= 42

45-42=3

I believe this is correct

Answer:

Answer:

Step-by-step explanation:

The measure of angle ∠WOV is 60 degrees and The measure of angle ∠YOZ is also 60 degrees.

What is an angle?

Angle is the space between the line or the surface that meets.  And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

∠WOX = 30

It can be seen that the ∠XOY and ∠VOX are equal and 90 degrees.

The measure of angle ∠WOV will be

∠WOV + ∠WOX = 90

     ∠WOV + 30 = 90

             ∠WOV = 60

The measure of angle ∠YOZ will be

∠WOX + ∠XOY + ∠YOZ = 180   (Supplementary angle)

          30 + 90 + ∠YOZ = 180

                           ∠YOZ = 60

Answer:

C

Step-by-step explanation:

In the Cartesian coordinate system, a line perpendicular to the line that's across the Y axis is a row across the X axis. You see Y=1 is the line across Y axis, so we need a row that's across the X axis. So C. X=4 is the ideal choice.

If a line is drawn on a coordinate grid by the equation y = 1 then x=4 would represent a row perpendicular to it.

A coordinate geometry is a branch of geometry where the position of the points on the plane is defined with the help of an ordered pair of numbers also known as coordinates.

A line is drawn on a coordinate grid by the equation y = 1.

The equation y = 1 represents a horizontal line on the coordinate grid, passing through all the points where y-coordinate is 1.

A line that is perpendicular to a horizontal line is a vertical line.

The vertical line x = 4 passes through all the points where x-coordinate is 4, and is perpendicular to the horizontal line y = 1.

Hence, if a line is drawn on a coordinate grid by the equation y = 1 then x=4 would represent a row perpendicular to it.
