mayflies can live at the bottom of lakes for 2 to 3 years before they become winged adults.Mayflies are between 4/10 inches and 1.6 inches long.If this mayfly is 4/10 of an inch long,how can you write 4/10 in simplest form.

Answers

Answer 1

Answer:
To simplify any fraction, look for a common factor in the top number
and the bottom number. If you find one, divide the top and bottom
both by their common factor. Eventually, you reach the point where
their only common factor is ' 1 ' ... that's when it's in simplest form.

4 and 10 both have 2 as a factor.

When you divide top and bottom both by 2, you have 2/5 .
This is the simplest form of 4/10 .

None of this has anything to do with mayflies. You can use the same
process to simplify fractions in ANY situation where fractions arise.

Variable y varies directly with variable x, and y = 6 when x = 9. What is the value of x when y = 18?

Answers

x and y are proportional hence when y is multiplied by a number, x is multiplied by the same number.

18=6*3 hence when y=18,x=9*3=27

x=27

so you can set up a proportion like
x/y=x/y
9/6=x/18
simplify 9/6=3/2
3/2=x/18
multiply both side by 18
(3x18)/2=x
54/2=x
x=27

Find the equation of the line that goes through the points (4, –1) and (2, –5).Use slope formula,m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction,to find the slope of a line that passes through the points.

Answers

Answer:

y = 2 x - 9

Step-by-step explanation:

slope = difference of y / difference of x

m = (-5 - (-1)) / (2 - 4) = -4 / -2 = 2

pass point (4 , -1)

y = mx + b b: y intercept

b = y - mx = -1 - 2 x 4 = -9

equation: y = 2 x - 9

Explain how you could mentally find 8 x 45 by using the distributive property

Answers

First, break up 45 into 40 and 5 then multipy 8(40) which equals 320 and multipy 8(5) which equals 40. Thrn add 320+40 to get the product 360.
Hope this helped

8x45
8(40)+8(5)
320+40
360

360 is the solution of the given mathematical expression.

To mentally find the product of 8 and 45 using the distributive property, you can break down one of the factors into smaller, more manageable parts.

First, decompose 45 into two parts, such as 40 and 5.

Now, you can distribute the factor of 8 to both parts:

8 x 40 + 8 x 5

Next, simplify each part individually:

8 x 40 = 320

8 x 5 = 40

Finally, add the results together:

320 + 40 = 360

So, mentally applying the distributive property, you can find that 8 multiplied by 45 equals 360.
