Answer:

821 bacteria

Step-by-step explanation:

You have that the growth of bacteria is represented by:

y = 79.31(1.48)x

N° Bacteria=79.31(1.48)(N° Days)

If you know that N° Days is 7, you need to replace x=7 in the Equation given.

Then:

N° Bacteria=79.31(1.48)(N° Days)

N° Bacteria=79.31(1.48)(7)

N° Bacteria=821,65

Write and solve an equation to find the value of x and a missing angle in the triangle below.
Arturiano [62]

Answer:

x = 27°, ∠JLK = 55°

Step-by-step explanation:

From the diagram in the question above,

The exterior angle of a triangle is equal to the sum of the two opposite side

3x+13 = 39+(2x+1)

3x+13 = 40+2x

collect like terms and solve for x

3x-2x = 40-13

x = 27°.

∠JKL = 2x+1

Substitute the value of x

∠JKL = 2(27)+1

∠JKL = 54+1

∠JKL = 55°
