Fill in missing numbers. 48.9÷0.03=... ÷ 3

Mathematics
1 answer:
shepuryov [24]3 years ago
8 0

Answer:

  4890

Step-by-step explanation:

Recognize the denominator has been multiplied by 100:

  0.03 × 100 = 3

To have the same division problem, the numerator must also be multiplied by 100. This is the sort of decimal point adjustment usually carried out for long division: the divisor is made to be an integer, and the decimal point of the dividend is moved the same direction by the same number of places.

  \dfrac{48.9}{0.03}=\dfrac{48.9\cdot 100}{0.03\cdot 100}=\dfrac{4890}{3}

The missing number is 4890.

____

The quotient is 1630.

Find the area of the shaded portion in each of the following​
MrRa [10]

Answer:

30.5 cm^2

Step-by-step explanation:

<h3><u>General outline</u></h3>
  1. Find the area of the full circle
  2. Find the area of the rectangle
  3. Find the difference (full circle area - rectangle area)

<h3><u>Step 1.  Find the area of the full circle</u></h3>

Recall the formula for the area of a circle: A_{circle}=\pi r^2 where \pi \approx 3.14, and "r" is the radius of the circle (distance from center to any point on the edge).

From the diagram, the radius is 5cm.

A_{circle}=\pi r^2

A_{circle}=(3.14)(5[cm])^2

A_{circle}=78.5[cm^2]

<h3><u>Step 2.  Find the area of the rectangle</u></h3>

Recall the formula for the area of a rectangle: A_{rectangle}=bh where "b" is the base of the rectangle (length of bottom or length of top), "h" is the height of the rectangle (distance from bottom to top).

From the diagram, the base is 8cm, and the height is 6cm.

A_{rectangle}=bh

A_{rectangle}=(8[cm])(6[cm])

A_{rectangle}=48[cm^2]

<u />

<h3><u>Step 3.  Find the difference (full circle area - rectangle area)</u></h3>

Having found the areas for each of the first parts, we can find the difference to find the shaded area:

A_{shaded}=A_{circle}-A_{rectangle}

A_{shaded}=(78.5[cm^2])-(48[cm^2])

A_{shaded}=30.5[cm^2]<u />
