100 POINTS!!! Which statement about rational numbers is correct?
Natasha_Volkova [10]

Answer: Rational numbers have decimal expansions that repeat or terminate.

Step-by-step explanation:

The explanation of this is the non-terminating but repeating decimal expansion means that although the decimal representation has an infinite number of digits, there is a repetitive pattern to it. The rational number whose denominator is having a factor other than 2 or 5, will not have a terminating decimal number as the result.

The relationship between a bacteria population p, in thousands, and time d, in days, since it was measured to be 1,000 can be re
Assoli18 [71]

d = log₂p represents a logarithmic function, The expression log₂(10) tells us when the population reaches 10,000 and the equation 7 = log₂(128) tells us that the population reaches 128,000 in 7 days.

<h3>What is an exponential function?</h3>

An exponential function is in the form:

y = abˣ

Where a is the initial value of y and b is the multiplication factor.

Let p represent the bacteria population in thousand after d days.

Since each day, the bacteria population grows by a factor of 2, hence:

p=2^d

Hence, d = log₂p represents a logarithmic function

The expression log₂(10) tells us when the population reaches 10,000 and the equation 7 = log₂(128) tells us that the population reaches 128,000 in 7 days.

The ratio of boys to girls in Mr.Greens class is 4 to 5. There are 8 boys in the class. How many girls in the class
Alex777 [14]

Answer:

10

Step-by-step explanation:

 B/G = 4/5

 8/G = 4/5     Multiply each side by 5

40/G = 4        Multiply each side by G

  40 =  4G      Divide each side by 4

    G =  10

There are 10 girls in the class.

Check:

8/10 = 4/5

4/5  = 4/5

In the trapezoid below, EF is parallel to BC. If ED = 35, BC = 63, DC = 28,
iren2701 [21]

EF and BC in the trapezoid below are parallel. if ED=35, BC=63, and DC=28

Find the length of BD if EF = 45. Not all figures are rendered to scale.

A trapezoid is a quadrilateral with one pair of opposite sides parallel. It can have right angles (a right trapezoid), and it can have congruent sides (isosceles), but those are not required.

The base angles and the diagonals of an isosceles trapezoid are equal. The intersection point of the diagonals is collinear to the midpoints of the two opposite sides. Opposite sides of an isosceles trapezoid are of the same length or congruent to each other.
