To get an A in a course, you must have an average of at least 90% on four tests worth 100 points each. Your scores so far are 85

kondaur [170]

Answer:

A score of 117 is needed, which Is not possible since the test is over 100.

Step-by-step explanation:

The other 3 scores are 85, 94,84 . Let's x be the 4th score he must score.

Therefore ( 85 + 94 + 84 + X)/4 =95

Then 263+X /4 =95

Cross mutiplying 4*95=263+X

Therefore X= 380-263

X= 117 which is not possible since the test score is over 100.

Please answer this question, ONLY IF YOU KNOW THE ANSWER. No guessing, 20 points and brainliest!

B. 3. Because if you have two people rolling a six sided die, with odd and even number contributions, you would divide 6 by 2. This is because there are TWO people going for TWO different types of numbers, odd and even. 6/2 gives us 3.

Hope this helps :)

What is the other square root of 119 + 120i?

MakcuM [25]

Answer:

$\sqrt{119+120 i}=\pm (12.24+i 4.90)$

Step-by-step explanation:

Given

z = 119 + 120 i

Let $\sqrt{119+120 i}=p+iq$

Squaring both sides

$119+120 i=p^2-q^2+2ipq$

Comparing real and imaginary part

Re(LHS)=Re(RHS)

$119=p^2-q^2$ ...........................(1)

comparing Im(LHS)=Im(RHS)

120=2pq

$q=\frac{60}{p}$

Substitute q in 1

$119=p^2-(\frac{60}{p})^2$

$p^4-119p^2-(68)^2=0$

Let $x=p^2$

$x^2-119x-4624=0$

$x=\dfrac{119\pm \sqrt{119^2+4\times 4624}}{2}$

$x=\frac{119\pm 180.71}{2}$

we take only Positive value because $p^2=x$

x=149.85

$p^2=149.85$

thus $p=\pm 12.24$

$q=\pm 4.90$

thus,

$\sqrt{119+120 i}=\pm (12.24+i 4.90)$
