To express a number in one unit as an equivalent value of another unit

1 answer:

4 0

A conversion factor is a number used to change one set of units to another, by multiplying or dividing. When a conversion is necessary, the appropriate conversion factor to an equal value must be used. For example, to convert inches to feet, the appropriate conversion value is 12 inches equal 1 foot.

This shape is made using three semicircles The smaller semicircle have diameters of 10cm Calculate the shaded area Take 3.142 an

CaHeK987 [17]

Answer:

The shaded area is 314.2 cm²

Step-by-step explanation:

Here we have the diameter, d₁ of the smaller semicircles as 10 cm

We note that the larger semicircle is subtended (bounded) by the two smaller semicircles;

1 shaded small semicircle and the other is blank

Therefore, the diameter, d₂ of the large semicircle = 10 + 10 = 20 cm

Also the area of the shaded figure consists of the removal of one small semicircle and the addition of the other semicircle to the area of the larger semicircle such that the area of the shaded figure is as follows

Shaded area of figure = π·d₂²/4 + π·d₁²/4 - π·d₁²/4 = π·d₂²/4 = π×20²/4 = 100×3.142 = 314.2 cm²

Shaded area = 314.2 cm².

Which pair of numbers is relatively prime?

Evgen [1.6K]

Answer:

<h2><u>PLEASE MARK BRAINLIEST!</u></h2>

Step-by-step Explanation:

<u>Answer - A</u>

<u />

Two numbers are relatively prime if they have no common factors (aside from 1). So lets solve for the factors of the number to see if they are relatively prime...

A. Relatively Prime

26=1,2,13,26

99=1,3,9,11,33,99

B. NOT RELATIVELY PRIME

90=1,2,3,5,6,9,10,15,18,30,45,90

117=1,3,9,13,39,117

C. NOT RELATIVELY PRIME

100=1,2,4,5,10,20,25,50,100

202=1,2,101,202

D. NOT RELATIVELY PRIME

201=1,3,67,201

444=1,2,3,4,6,12,37,74,111,148,222,444

Find the perimeter of a triangle with sides 2x - 3y, x2 + y and 2x + y units

Lesechka [4]

Perimeter = (2x -3y) + (x² + 7) + (2x + y)
Perimeter = 2x -3y + x² + 7 + 2x + y
Perimeter = x² + 4x - 2y + 7

------------------------------------
Answer: x² + 4x - 2y + 7
