Answer:

the number of viruses are in Dish A is 3,391 viruses

Step-by-step explanation:

The computation of the number of viruses are in Dish A is shown below:

Since there are 2826 square milimeters area

And, the population density of 1.2 viruses per square

So, the number of viruses in Dish A is

= 2826 × 1.2

= 3,391.2v viruses

Hence, the number of viruses are in Dish A is 3,391 viruses

Thirty percent of the students in a high school face a disciplinary action of some kind before they graduate. Of those students,
BaLLatris [955]

Answer:

54% of the students from the high school go on to college

Step-by-step explanation:

We have these following percentages:

30% of the students from a high school face a disciplinary action of some kind before they graduate. Of those, 40% go on to college.

70% do not face action, and of those, 60% go to college.

What percent of the students from the high school go on to college?

Sum of 40% of 30%(face disciplinary action) and 70% of 60%(do not

face disciplinary action). So

0.4*0.3 + 0.7*0.6 = 0.12 + 0.42 = 0.54

54% of the students from the high school go on to college

World problem in length (trigonometry) geometry not chemistry
lions [1.4K]

Answer:

≈ 47.2 m

Step-by-step explanation:

let the height from the sea to the base of lighthouse be h₁

let the height from the sea to the top of the lighthouse be h₂

using the tangent ratio in the right triangle

tan55.1° = \frac{opposite}{adjacent} = \frac{h_{1} }{610} ( multiply both sides by 610 )

h₁ = 610 tan55.1°

tan56.5° = \frac{h_{2} }{610} ( multiply both sides by 610 )

h₂ = 610 tan56.5°

then

height of lighthouse = h₂ - h₁        

                                  = 610 tan56.5° - 610 tan55.1°

                                  = 610(tan56.5° - tan55.1° )

                                 ≈ 47.2 m ( to the nearest tenth )

If the numbers -2.5, -1.6, -3 1/10, - 1/10, and -0.5 were graphed on a number line, which would appear farthest to the left?
Leona [35]
Turn the question around.
If all the numbers were positive: 2.5, 1.6, 3 1/10, 1/10, and 0.5, which would be farthest to the right?

The fact is that the negative numbers are a reflection of the positive numbers.
Since 3 1/10 would be farthest to the right with positive numbers, -3 1/10 will be farthest to the left with the negative numbers.

When doing unit rates, do you put pounds or money as the nominator?
Natalka [10]
Hello! When solving or writing unit rates, it is important to remember the denominator is always 1. The numerator would be pounds, as it is more specific than the general term money. Hope this helps! :)
