A culture started with 5000 bacteria. after 7 hours, it grew to 6500 bacteria. predict how many bacteria will be present after 1

spin [16.1K]

6500=7x+5000

6500-5000=7x+5000-5000

1500=7x

1500/7≈214

x≈214

y=19·214+5000

y=9066

answer=9066 bacteria

Are the only bases that I need to use 2 and 4 along with the height 2.5 and I just ignore the 3?

Answer:

$7.5\ units^2$

Step-by-step explanation:

The formula to find the area of a trapezoid is the following,

$A=(h)(\frac{(b_1)+(b_2)}{2})$

Where ( $h$ ) represents the heights of the trapezoid, ( $b_1$ ) and ( $b_2$ ) represent the bases of the trapezoid, or rather the two parallel sides of the trapezoid.

One is given all of these values in the picture,

$h = 2.5\\\\b_1 = 2\\\\b_2 = 4$

Substitute these values into the formula and solve for the area of the trapezoid,

$A=(2.5)(\frac{(2)+(4)}{2})$

Simplify,

$=(2.5)(\frac{6}{2})\\=(2.5)(3)\\=7.5$
