Answer:

A) Hummingbirds drinking nectar from a plant.

Step-by-step explanation:

Here are some examples of natural selection: In a habitat there are red bugs and green bugs. The birds prefer the taste of the red bugs, so soon there are many green bugs and few red bugs. The green bugs reproduce and make more green bugs and eventually there are no more red bugs.

Please tell me how you got it.

<u>Answer-</u>

$-70\%$

<u>Solution-</u>

The given data as follows,

$-70\%,\ 0.34,\ -\dfrac{2}{5},\ 0.96\%$

After converting all the percentages and fractions to decimal, we can compare them all.

For converting percentages to decimal to divide the number by 100, so

$-70\%=\dfrac{-70}{100}=-0.70,\\\\0.96\%=\dfrac{0.96}{100} =0.0096$

Then converting the fraction into decimal,

$-\dfrac{2}{5}=-\dfrac{2\times 20}{5\times 20}=-\dfrac{40}{100}=-0.40$

As, all the numbers are converted into decimal, now comparing all the numbers,

$-0.70$

$-70\%$

An arithmetic sequence has the terms a6=53 a 6 = 53 and a8=61 a 8 = 61 . Questions: What is the value of d d ? AnswerIncorrect W

leonid [27]

The given terms are two terms apart, so their difference is twice the difference of adjacent terms.

$a_8-a_6=2d=61-53=8\\\\d=\dfrac{8}{2}=4$

The value of d is 4.

Rewrite 6/9 fraction two different ways

2/3 (simply simplify/divide them by 3)
Or
.66666 (basically repeating numbers)
Or
66.6 % (Make sure for the decimal or percentage you write a line above the 6 after the 1st number behind the decimal to show it as a repeating number!)

Choose the formula for finding the slope m of a nonvertical line that contains the two distinct points left parenthesis x 1 comm

scoray [572]

$\text{Consider the nonvertical line passing through the points }(x_1,y_1)\\
\text{and }(x_2, y_2).\\
\\
\text{we know that slope of any line is the angle between the line from the}\\
\text{positive x-axis.}\\
\\
\text{The slope of a line is given by the ratio of rise over run.}\\
\\
\text{that is the ratio of the differnce of y-coordinates to the difference}\\
\text{to the difference of the x-coordinate.}$

$\text{hence the slope of the nonvertical line through the given points is}\\
\\
m=\frac{y_2-y_1}{x_2-x_1}$
