Answer:

Total impedance in circuit = 8 - 2j ohms

Step-by-step explanation:

Given:

Circuit one = 1 + 3j ohms

Circuit two = 7 - 5j ohms

Find:

Total impedance in circuit

Computation:

Total impedance in circuit = Circuit one + Circuit two

Total impedance in circuit = 1 + 3j + 7 - 5j

Total impedance in circuit = 8 - 2j ohms

Shawn earned $2.77 per day for three days as interest on his $1,000.00 investment. What percent interest did he earn in total? G
Nady [450]

Answer: He earned 0.831% interest in total.

Step-by-step explanation:

Given: Shawn earned $2.77 per day for three days as interest on his $1,000.00 investment.

Interest per day = $2.77

Interest in 3 days = 3 x ($2.77)

= $8.31

Invested amount= $1000

Required percentage of earnings = \dfrac{\text{Interest earned in 3 days}}{\text{Initial investment}}\times100

=\dfrac{8.31}{1000}\times100=0.831\%

Hence, he earned 0.831% interest in total.

PLEASE HELP ME AND MY FRIEND NEED THIS QUESTION ANSWERED PLEASE HELP
Bas_tet [7]

Answer:

V_{cone} =65.94\: cm^3

Step-by-step explanation:

  • Height of cone (h) = 7 cm

  • Base radius (r) = 3 cm

  • Formula for Volume of cone is given as:

  • V_{cone} = \frac{1}{3}\pi r^2h

  • Plugging the values of h and r in the above formula, we find:

  • V_{cone} = \frac{1}{3}(3.14) (3)^2(7)

  • \implies V_{cone} = \frac{1}{\cancel 3}(3.14) (\cancel 9)(7)

  • \implies V_{cone} = (3.14) (3)(7)

  • \implies V_{cone} =65.94\: cm^3

Asher has about a probability of winning then Ethan has which could be the outcome that Ashlee needs to win the game select thre
mash [69]

Answer:

There are 36 total possible outcomes.

Rolling a sum of 11 or higher, there are 3 possible rolls, to make a 3/36 = 1/12 probability.

Rolling a sum of 4 there are also 3 possibilities, so the chance would be the same.

Rolling a sum of 9, there are 4 possibilities, which is a better chance.

Rolling a sum less than 5, there is 6 possibilities, which is a better chance.

Rolling greater than 5 but less than 7 means rolling a sum of 6, there are 5 chances, which is a better chance.

Rolling greater than 9 but less than 11, means rolling a 10, there are 3 possibilities, which is the same.

Rolling greater than 2 and less than 4 means rolling a 3, there are 2 possibilities, which is less.

The answers would be:

Rolling a sum of 9,

Rolling a sum less than 5

Rolling greater than 5 but less than 7
