Clara bought 16 cases of water bottles. There were 12 water bottles in each case. Four students wrote and solved equations to find b, the number of bottles that Clara bought. Which student wrote and solved the equation correctly?
Maya’s work:
StartFraction b Over 12 EndFraction = 16. b = 1.3
Larissa’s work:
12 b = 16. b = 1.3
Sally’s work:
StartFraction b Over 12 EndFraction = 16. b = 192.
Anika’s work:StartFraction 12 Over b EndFraction = 16. b = 192.

Answers

Answer 1

Answer:

Sally is correct

Step-by-step explanation:

[tex]\frac{b}{12} =16[/tex]

to solve for b we can multiply both sides by 12 to get b alone.

b = 16 × 12

b = 192

The number N of bacteria present in a culture at time t (in hours) obeys the equation N = 1000e^0.01t After how many hours will the population equal 1500? 2000?​

Answers

Answer: N(t) = (2^t)*1500

Step-by-step explanation:

Let's define the hour "zero" as the initial population.

So if N(t)  is the number of bacteria after t hours, then:

N(0) = 1500.

Now, we know that the population doubles every hour, so we will have that after one hour, at t = 1

N(1) = 2*1500 = 3000

after two hours, at t = 2.

N(2) = 2*(2*1500) = (2^2)*1500

After three hours, at t = 3

N(3) = 2*(2^2)*1500 = (2^3)*1500

So we already can see the pattern, the number of bacteria after t hours will be:

N(t) = (2^t)*1500

An airplane takes off at a speed S of 226 mph at an angle of 18° with the horizontal. Resolve the vector S into components.

Answers

Velocity=226mph

Angle made with horizontal= 18°

The vector components would be [tex] 226~sin18° \hat{j} + 226~cos18° \hat{i} [/tex]

The vector components of Speed is [tex]\rm v_x[/tex] = 226 cos 18° and [tex]\rm v_y[/tex] = 226 sin 18°

What is a Vector ?

An parameter that has both magnitude and direction is called a vector.

It is given that

Speed S = 226 mph

Angle = 18 degree with the horizontal

The vector component are

[tex]\rm v_x , v_y[/tex]

here these are x and y components of the vector

V is the magnitude = |v| = 226

The vector component is given by

cos [tex]\rm \theta[/tex] = [tex]\rm v_x[/tex] / |v|

[tex]\rm v_x[/tex] = 226 cos 18°

[tex]\rm v_y[/tex] = 226 sin 18°

Therefore the vector components of Speed is [tex]\rm v_x[/tex] = 226 cos 18° and [tex]\rm v_y[/tex] = 226 sin 18°
