A boy does 20J of work in 4s. Find his Power.​

Answers

Answer 1
Power = work divided by time. So, to get the answer you’re looking for, you have to do 20J divided by 4 seconds, which will get you 5 horsepower.
Answer 2

Answer:

5 watts

Step-by-step explanation:

power (measured in watts) is joules per second, or J/s

J = 20

s = 4

A growth medium is inoculated with 1,000 bacteria, which grow at a rate of 15% each day. What is the population of the culture 6 days after inoculation?

y = 1,000(1.15)6; 2,313 bacteria
y = 1,000(1.15)7; 2,660 bacteria
y = 1,000(1.5)5; 7,594 bacteria
y = 1,000(1.5)6; 11,391 bacteria

Answers

Answer:

A

Step-by-step explanation:

The population of the culture 6 days after inoculation is 2,313.

Correct option is (A).

What is Compounding?

When interest is earned and then reinvested, the total interest on the principle is calculated using compounding. It causes assets or capital to increase exponentially for investors.

As per the given data:

Number of bacteria initially (P) = 1000

Growth rate of the bacteria = 15% each day

Growth rate of the bacteria in decimal (r) = 0.15

Number of days (n) = 6

The bacteria is growing each day with 15% each day, hence it is compounding.

The population of the culture 6 days after inoculation (y):

[tex]y = P (1+r)^t[/tex]

[tex]y = 1000 (1+0.15)^6[/tex]

[tex]y = 1000 (1.15)^6[/tex]

y = 2,313

Hence, The population of the culture 6 days after inoculation is 2,313.

Find the ten missing angles labeled in the diagram. Line a is parallel to line b. The measures of two angles are given.​

Answers

Answer:

m∠3 = 112°     m∠5 = 38°     m∠6 = 68°    m∠8 = 74°

You do the others

Step-by-step explanation:

Facts you need to solve this problem.

1.  Vertical angles are congruent

2.  Alternate interior angles are congruent when lines are parallel

3.  Sum of the measures of the angles of a triangle is 180

4.  Adjacent angles are supplementary when two lines intersect

m∠3 = 112°   (Reason 1 above)

m∠6 = 180 - 112 = 68°   (Reason 4)

m∠6 + m∠5 + 74 = 180°  (Reason 3)

68 + m∠5 + 74 = 180

142 + m∠5 = 180

m∠5 = 38°

m∠8 = 74°  (Reason 2)

That gives you a start, so I will let you find all the others.  OK?  I know you don't want to do that, but you need to be able to do this type of problem.  Now, go for it!!
