Answer:
V = 29 + j3
Step-by-step explanation:
4+j3 amps and resistance of 5-j3 ohms what is the voltage of the circuit
V = IR I = 4+j3 amps R = 5-j3 ohms
V = 4+j3 × 5-j3
V = [4 × 5]+[j3 × -j3] + [4 × -j3] + [j3 × 5]
V = 20 + (-j²)9 + (-j12) + j15
V = 20 - 9 + j3 j3 × -j3 = 9 not -9 j = -1 j × j = -1 not 1 my mistake
V = 11 + j3 WRONG
my daughter's old TI 84 Plus Silver Edtion calculator got 29+j3

The lines graphed below show the amounts of water in two tanks as they
were being filed over time.
Which tank shows a proportional relationship between the amount of
water, in gallons, and the time, in minutes?
Answer:
Tank B
Step-by-step explanation:
Proportional relationships are relationships between two variables with equivalent ratios. For a proportional relationship, one variable is always a constant value times the other. A line is a proportional relationship if it starts from the origin, but if it does not start from the origin, it is not proportional.
From the two tanks, we can see that tank A have a y intercept whereas tank B starts from the origin. Therefore tank B shows a proportional relationship.
Aysha got a dress that was on 20% off of the original price of $25.40. How much did she get the dress for?
Answer:
20.32$
Step-by-step explanation:
25.40×.20 = 5.08
25.40- 5.08 = 20.32
so the answer would be 20.32$
What triangle is formed by the points (3,2), (4,7), and (5,6)?
Answer:
Scalene Triangle
Step.-by-step explanation:
Calculate the lengths of the sides:
Side 1 = √((4-3)^2+(7-2)^2) = √26.
Side 2 = √((6-7)^2+(5-4)^2) = √2.
Side 3 = √((6-2)^2+(5-3)^2) = √20.
So each side is different in length and so its a scalene triangle.
It takes an older pump 4 times as long to drain a certain pool as it does a newer pump. Working together, it takes the two pumps 3 hours to drain the pool. How
long will it take the newer pump to drain the pool working alone?
Do not do any rounding.
Answer:
New pump = 3.75 hours
Old pump = 15 hours
Step-by-step explanation:
Let :
Time taken by newer pump = x hrs
Time taken by older pump = 4x hrs
Time taken when working together = 3 hours
Drain rate :
Newer pump = 1/x
Older pump = 1/4x
Combined = 1/3
Hence :
Newer pump rate + older pump rate = combined rate
1/x + 1/4x = 1/3
Take the lcm
(4 + 1) / 4x = 1/3
Cross multiply
5 * 3 = 4x
15 = 4x
x = 15/4
x = 3.75
The old pump will take :
4x = 4 * 3.75 = 15 hours
Sarah earns $340 per week and spends 20% of her earnings on transportation. How much does Sarah spend on transportation every week?
Answer:
$68
Step-by-step explanation:
=> 20% 0f 340
=> (20/100) * 340
=> (1/5) * 340
=> (340/5) = 68
Sarah spends $68 dollar on transportation.

Solve for (n): 110 = n/10
Answer:
n = 1100
Step-by-step explanation:
Isolate the variable, n. Note the equal sign, what you do to one side, you do to the other. Multiply 10 to both sides of the equation:
110 = n/10
(110) * 10 = (n/10) * 10
n = 110 * 10
n = 1100
1100 is your answer for n.
~
Answer:
1100 = n
Step-by-step explanation:
➟ 110 = n/10
➟ 110 × 10 = n
➟ 1100 = n
Hope it helpsInstead of power posing in horses, you are interested in whether music can induce a mere exposure effect at short timescales. You read a paper that claims that it can, reporting a significant mere exposure effect. Alpha level was 0.05, the ratio of true to false effects in this field is 0.7 and the power of this study was 0.8. The probability that this effect is real is
Answer:
"0.9739" is the correct answer.
Step-by-step explanation:
The given values are:
The ratio of true to false effects,
= 0.07
The power of study,
= 0.8
Alpha level,
= 0.05
Now,
The percentage of effects proved as significant will be:
= [tex]0.8\times \ 70 \ percentage[/tex]
= [tex]0.56[/tex]
0r,
= [tex]56[/tex]%
The percentage of false effects will be:
= [tex]0.05\times 30 \ percent[/tex]
= [tex]0.015[/tex]
or,
= [tex]1.5[/tex]%
The total effects will be:
= [tex]56+1.5[/tex]
= [tex]57.5[/tex]%
hence,
The probability that this effect is real will be:
= [tex]\frac{56}{57.5}[/tex]
= [tex]0.9739[/tex]

interest rate is 8.9%?
A. 0.74
B. 0.74
C. 0.0074
D. 0.0089
Answer:
c
Step-by-step explanation:
<3
The monthly rate of interest is 0.0074. Therefore, option C is the correct answer.
What is the rate of interest?An interest rate tells you how high the cost of borrowing is, or high the rewards are for saving. So, if you're a borrower, the interest rate is the amount you are charged for borrowing money, shown as a percentage of the total amount of the loan.
The given rate of interest is 8.9%.
The monthly payment formula is M = Pr(1+ r)ⁿ/(1+ r)ⁿ - 1
Here, rate of interest
= 8.9%/12
= 0.089/12
= 0.0074
Therefore, option C is the correct answer.

A model car is built on a 1:16 scale
If the wheelbase on the actual car is 186 inches, what is the wheelbase on the model? Give your answer as a decimal. Do not round and do not include the units.
Answer:
11.625inches
Step-by-step explanation:
If a model car is built on a 1:16 scale and the length of actual car is 186inches
16inches = 1
186inches = x
16* x = 186
x = 186/16
x = 11.625
hence the wheel base of the model is 11.625inches

Find the volume of a pyramid with a square base, where the area of the base is
12.2 m² and the height of the pyramid is 12.3 m. Round your answer to the nearest
tenth of a cubic meter.
Answer:
50.0 cm²
Step-by-step explanation:
Applying
Volume of a pyramid (V) = 1/3×Area of the base(A')×Heigth(H)
A= 1/3A'h.................... Equation 1
A' = Area of the base, h = height of the pyramid
From the question,
Given: A' = 12.2 m², h = 12.3 m
Substitute these values into equation 1
A = 1/3(12.2×12.3)
A = 50.02
A = 50.02 cm²
A = 50.0 cm²
