What is the resistance of a 1.00X10^2 -Ω , a 2.50-kΩ , and a 4.00-k Ω resistor connected in parallel?

Answers

Answer:

Therefore, the total Resistance:  R = 93.9 Ω

Step-by-step explanation:

Given

R₁ = 1 × 10²

R₂ = 2.5 kΩ = 2.5 × 10³ Ω

R₃ = 4  kΩ = 4 × 10³ Ω

Given that the given resisters are connected parallel, so using the formula to calculate the total Resistance R:

[tex]\frac{1}{R}\:=\:\frac{1}{R_1}\:+\:\frac{1}{R_2}+\frac{1}{R_3}[/tex]

susbtituting R₁ = 1 × 10², R₂ = 2.5 × 10³ Ω, and R₃ = 4 × 10³ Ω

[tex]\frac{1}{R}=\frac{1}{1\times \:10^2}+\frac{1}{2.5\times \:10^3}+\frac{1}{4\times \:10^3}[/tex]

Multiply by LCM of R, 100, 2500, and 4000:   20000 R

[tex]\frac{1}{R}\cdot \:20000R=\frac{1}{1\cdot \:10^2}\cdot \:20000R+\frac{1}{2.5\cdot \:10^3}\cdot \:20000R+\frac{1}{4\cdot \:10^3}\cdot \:20000R[/tex]

simplify

[tex]20000=213R[/tex]

Switch sides

[tex]213R=20000[/tex]

Divide both sides by 213

[tex]\frac{213R}{213}=\frac{20000}{213}[/tex]

Simplify

[tex]R=\frac{20000}{213}[/tex]

[tex]R = 93.9[/tex] Ω

Therefore, the total Resistance:  R = 93.9 Ω

You have 29 thirds. This is a fraction greater than one.
How many wholes can I make with that?
How many thirds would be left over?

Answers

You could make 9 wholes with that and there would be 2 thirds left over.

To solve it you would just have to divide 29 by 3 which would give you 9 and leave you with 2 thirds left.

mean- 60
mode- 48
median- 56
range- 32

Answer:

Mean = 60

Median = 56

Mode = 48

Range = 32

Step-by-step explanation: You can find the Mean by adding all the number together then dividing by how many number in the problem. So, 48 + 64 + 80 + 48 = 240 then, divide by 4, which is how many numbers are in this equation.  You can find the Median by putting the numbers in the equation in order, 48, 48, 64, 80. Then, you will find what number is in the middle, or look at it as for the number in the middle to have the same amount of numbers on each side. So, in this case 48 and 64 are in the middle. There are two numbers in the middle instead of one, so you have to add them together to get 112 then divide by 2, because it is how many numbers you added together. You can find the Mode by seeing what number occurs the most, which in this case is 48, it appears two times. Sometimes, there will be no mode. You can find the Range by putting the numbers in order and subtracting the highest amount from the lowest amount, which in this case is 80 - 48 = 32. Hope this helps ^-^

A student was selected as a captain of a cooking team in a consumer and family studies class. The student could pick 2 of 5 girls and 3 of 7 boys to be on their team. What is the total number of different teams that this captain could select?

Answers

Answer:

This captain could select 350 different teams.

Step-by-step explanation:

The order in which the girls and the boys are picked is not important. For example, picking Daniela and Laura is the same as picking Laura and Daniela. So we use the combinations formula to solve this question.

Combinations Formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

Girls:

2 from a set of 5. So

[tex]C_{5,2} = \frac{5!}{2!(5-2)!} = 10[/tex]

Boys:

3 from a set of 7. So

[tex]C_{7,3} = \frac{7!}{3!(7-3)!} = 35[/tex]

Total:

[tex]10*35 = 350[/tex]

This captain could select 350 different teams.
