How are fraction and decimals related

Answers

Answer 1

Answer: They are both parts of a whole

Answer 2

Answer: Fractions and decimals are simply two different ways of expressing a number. A fraction expresses a number in the form of two other numbers, where the top number in the fraction is being divided by the bottom number. ie. if the fraction was written as x/y, then the fraction would be expressing the number x divided by the number y. A decimal, on the other hand is an expression of a number in a more traditional form, in one single line of numbers, with a decimal point preceeding all of it. To convert a fraction to a decimal, we do what the fraction says, in that we divide the top number by the bottom number. For example, the fraction 3/4 (3 quarters) = 0.75, as 3 divided by 4 = 0.75. The reason we use fractions and dont just make everything a decimal, is that sometimes it is easier to calculate something or express a number using a fraction. For example, when working with irrational numbers, the decimal is actually infinite, so it is impossible to write as a decimal and be 100% accurate, however if written as a fraction, it can be expressed exactly. For example the fraction 1/3 = 0.333333 where the 3s continue forever :))

Consider the following two circles. Circle P with center (-1, 2) and radius 3 and circle Q with center (3, 4) radius 5. What sequence of transformations will carry circle P onto circle Q? Select all that apply.A. Dilation centered at Q, followed by reflection across the y-axisB. Dilation centered at P, followed by reflection across the y-axis and then the line y = -x + 5C. Translation (x,y) -> (x+4, y+2), followed by dilation centered at QD. Dilation (x+y) -> (3/5x, 3/5y), followed by dilation centered at PE. Reflection over x-axis followed by rotation of 270 degrees

b.–172
c.28
d. 72

Answers

Discriminant is 28 (c) First get the equation into the form: Ax^2 + Bx + C = 0 (the quadratic equation).. By subtracting 10x both sides (to get it on the other side).. 9x^2 + 2 = 10x 9x^2 - 10x + 2 = 10x - 10x 9x^2 - 10x + 2 = 0 Now the discriminant is: b^2 - 4ac The quadratic equation is Ax^2 + Bx + C = 0 Here, A = 9, B = -10 and C = 2 (-10)^2 - 4 (9)(2) = 100 - 4 (18) = 100 - 72 = 28

Answers

An area of a circle is calculated by the formula pi(3.14) x radius^2 (squared)

This mean that you would have to type pi x 50^2 (squared) into your calculator which would equal 7853.98. Then round it up to equal 7854cm^2
