Answer:

y=1/2x+4 1/2

Step-by-step explanation:

You first find the slope, which is (y1-y2)/(x1-x2)

So in this case, it is 5-1/1-3, which equals -1/-2=1/2

So now that you have m, you plug in y and x using either point, in this case i will use (1,5)

Slope intercept form is y=mx+b

Y is y point, m is slope, x is x point, and b is y intercept

So the equation is 5=1/2(1)+b

you solve the equation and get

5=1/2+b

4 1/2=b

so the final equation in slope intercept form is y=1/2x+4 1/2

a culture started with 5000 bacteria after 2 hours it grew to 6500 predict how mabacteria will be present after 18 hours

Lena [83]

In 18 hour it grew 13,500, because it grew 1,500 in 2 hour and if you divide 18 by 2 it is 9 so 1,500 time 2 is 13,500.
hopefully I am correct and this helps you.

Answer:

√27

Step-by-step explanation:

The triangles of the pyramid are equilateral triangles with sides of 6''.

Dividing a triangle into two equal parts we get two congruent right triangles, with a hypotenuse of 6'', one leg of 3'', and the other leg is the slant height (s). From Pythagorean theorem:

3² + s² = 6²

s² = 6² - 3²

s = √27

Perform the following division:

Radda [10]

Hey!

Alright, the first step to solving this division problem would be to convert the mixed fraction into a simple fraction. To do that, we'll multiply the denominator by the whole number and then add that total to the numerator.

Original Fraction :
$3 \frac{3}{4}$

New Fraction {Changed by Conversion} :
$\frac{15}{4}$

Now that we've successfully done that we'll have to change the equation.

Old Equation :
$\frac{15}{4}$ ÷ $\frac{2}{8}$ = ?

New Equation {Changed by Flipping the Second Fraction and the Symbol} :
$\frac{15}{4}$ · $\frac{8}{2}$ = ?

Now we multiply straight across.

Old Equation :
$\frac{15}{4}$ · $\frac{8}{2}$ = ?

Solved :
$\frac{120}{8}$

Almost done!
Now we have to simplify the fraction.

Old Fraction :
$\frac{120}{8}$

New Fraction {Changed by Simplification} :
$\frac{15}{1}$

Now just convert it to a whole number by removing the fraction line and the number, and that's it!

So, $3 \frac{3}{4}$ ÷ $\frac{2}{8}$ equals 15.

Hope this helps!

A number is less than 30 but greater than 10.

The answer is 16 and 26. Both are less than 30 and greater than 10 and have 6 in the one’s place.
