Help, please the question and thank you
Law Incorporation [45]

Answer:

The scale factor is 1.5.

Step-by-step explanation:

Divide the length of the image, 12, by the length of the preimage, 8, which will give you 1.5

12 ÷ 8 = 1.5

Therefore, the scale factor of the image is 1.5.

A scientist has a sample of bacteria that initially contains 10 million microbes. They observe the sample and finds that the num
sergiy2304 [10]

Answer:

M(t) = 6.7 * 10⁷ (67 million)

Minutes (t) =55

Step-by-step explanation:

1. Write an exponential equation that represents M, the total number of bacterial microbes in millions, as a function of t, the number of minutes the sample has been observed.

For answering this question, we will use the following formula:

M(t) = B₀ * g ^(t/m), where:

•M(t) represents the total number of bacterial microbes in millions.

• B₀ represents the initial population of bacteria in millions.

• g represents the growth factor.

• t represents the total number of minutes we will observe the bacteria growing.

• m represents the time in minutes it takes to the growth factor g to occur.

2. Then, determine how much time, to the nearest minute, will pass until there are 67 million bacterial microbes.

M(t) = B₀ * g ^(t/m)

Replacing with the values we know:

6.7 * 10⁷ = 10⁷ * 2 ^(t/20)

6.7 = 2 ^(t/20) (Dividing by 10⁷ at both sides)

ln 6.7 = ln 2 ^(t/20)

ln 6.7 = t/20 ln 2

ln 6.7/ ln 2 = t/20

t = ln 6.7/ln 2 * 20

t = 2.74 * 20

t = 54.88

t ≅ 55 (rounding to the nearest minute)

The equation x + 2y = 16 is in standard form.
zheka24 [161]
X+2y=16
Subtract x from both sides
2y= -x+16
Divide both sides by 2
Y=-1/2x+8
Slope is -1/2 or - .5

In the diagram below, what needs to be labeled in order to prove triangle AHL and triangle EML are congruent by the SSS postulat
Kobotan [32]

Answer:

HL = LM

Step-by-step explanation:

We have been given a diagram in which sides AH= EM and AL=EL.

Now we need to find which statement is missing to prove that triangles AHL and EML are congruent using SSS.

SSS means (side - side - side)

Two pair of equal sides are already given so we have completed SS of SSS.

Last "S" means we need one more pair of equal sides so that must be using remaining sides HL and LM

Hence final answer is HL = LM.
