Q1) AC = √4.8²+3.6²
= √36
= 6cm
Q2) AB= √17.55² - 6.75²
= √262.44
= 16.2cm
Q3) BC= √14² - 6²
= √160
= 12.64911
= 12.6 cm (to 3sf)
Answer:
1) AC = 6 cm
2) AB = 16.2 cm ( note that ^{2} is = square and \sqrt{ this is = square root)
3) BC = 12.65cm
Step-by-step explanation:
1) a^{2} + b^{2} = c^{2}
4.8^{2} + 3.6^{2} = AC^{2}
36 = AC^{2}
\sqrt{ }36 = AC
AC = 6
2) a^{2} + b^{2} = c^{2}
AB^{2} + 6.75^{2} = 17.55^{2}
AB^{2} = 308.0025 - 25.5625
AB = \sqrt{ }262.44
AB = 16.2
3) a^{2} + b^{2} = c^{2}
BC^{2} + 6^{2} = 14^{2}
BC^{2} = 196 - 36
BC = \sqrt{ } 160
BC = 12.65
I hope this helps a little bit.

If the lowest price in the past year occurred 48 days ago, find the approximate average change per day since then.
Answers
Answer:
0.72
Step-by-step explanation:
According to the stock listing mentioned in the listing for Enam Telecom is
52 wk high = 122.86
52 wk low = 64.77
Div. = 3.45
Close = 99.14
Net change = 4.74
Now it is mentioned that lesser price i.e. 64.77 arised 48 days ago.
As yesterday closing price was 99.14
So, the net change in value would be
= 99.14 - 64.77
= 34.37
For 48 days, the average change per day would be
= Total change ÷ number of days
= 34.37 ÷ 48
= 0.716
= 0.72

The graph below shows the solution to which system of inequalities?
Answers
Answer:
B: y >= 2
y < x
Step-by-step explanation:
The system of equations is the equations of the two line
The flat line is constant (doesn't increase or decrease) and has a y-intercept at two, so the equation for it is y = 2. Notice the shaded region is above the line, and it is not a dotted line so it is y >= 2.
The second line has a y-intercept at 0 and seems to have a slope of 1, so the equation for it is y = x. Notice the shaded region is below the line, and it is a dotted line so it is y < x.
find each probability a coin landing heads up on every toss when it is tossed 3 times
Answers
Answer:
Their is not enough information
Step-by-step explanation:
Answer:
Step-by-step explanation:Consider coin 1:
It has to be either HEADS or TAILS (obviously). If it's a “Fair” coin the probability of getting either a Heads or Tails is (1/2) for each option.
Conclusion(so far):
Prob (Heads Coin 1) = (1/2) AND
Prob (Tails Coin 1) = (1/2)
To meet the requirements of the question, the second coin toss must have the same result as for the first coin toss.
So if the result for Coin 1 was Heads then the result for Coin 2 must also be Heads.
So
(Prob (Heads Coin 1 AND Heads Coin 2) = (Prob Heads Coin1) * (Prob Heads Coin 2) = (1/2)*(1/2) = (1/4)
Conclusion (so far) (2 coins tossed):
Prob of two coin tosses BOTH giving Heads is (1/2)*(1/2) = (1/4)
AND similarly
Prob of two coin tosses BOTH giving Tails is also (1/2)*(1/2) = (1/4)
To meet the requirements of the question, the third coin toss will, by definition be either HEADS or TAILS.
AND
Prob (Coin 3 Heads) = (1/2) AND
Prob (Coin 3 Tails) = (1/2)
The question is clear: We are asked to find the Probability that the (3 tosses) are the same.
That is, if the first toss (Coin 1) is Heads, then the results for Coin 2 and Coin 3 tosses must also be Heads.
Similarly if the the first toss (Coin 1) is Tails, then the results for Coin 2 and Coin 3 tosses must also be Tails.
So for the tosses for Coins 1, 2 and 3 to each be Heads, we have:
Prob (Coin 1 Heads, Coin 2 Heads, Coin 3 Heads) = (1/2)*(1/2)*(1/2) = (1/8)
AND
Prob (Coin 1 Tails, Coin 2 Tails, Coin 3 Tails) = (1/2)*(1/2)*(1/2) = (1/8)
There are NO OTHER NUMBER COMBINATIONS WHICH MEET THE REQUIREMENTS OF THE QUESTION other than 3 Heads AND 3 Tails.
It is important to note THAT THE SITUATIONS ABOVE (3 Heads AND 3 Tails) are BOTH VALID SOLUTIONS.
Therefore
The Probability for 3 Heads is (1/8)
AND
The Probability for 3 Tails is (1/8)
BUT BOTH THESE SOLUTIONS ARE VALID PROBABILITIES and BOTH meet the requirements of the question.
Therefore the overall probability is THE SUM OF BOTH PROBABILITIES, that is:
The probability that after 3 tosses, the tosses of each coin ALL give the same result is:
(1/8) + (1/8) = (2/8) = (1/4) or 0.25 or 25%
This means that after 3 coin tosses there is a 25% probability that we will get either 3 Heads or 3 Tails.
(A note of interest: It would be an error to ignore the fact that there are TWO valid number combinations which meet the requirements of the question, not one).
(In my analysis above I have identified ONLY the valid-number combinations and spent little time considering non-valid-number combination).

Step-by-step explanation:
Let's take a problem such as 3x-2=6
To isolate the variable, you must get rid of everything on one side and essentially do the inverse to the other side. We see -2, so you have to add 2 to each side.
Now you have 3x=8
Next, we device each side by 3. Right now, x is being multiplied by 3 so we have to do the inverse.
Answer is x = 8/3 or 2.666666666666667

10^a is above 10^4 and in the next step that equals 1, so 10^a would need to be 10^4 because any number divided by itself equals 1.
Now if a is 4 then b needs to be 15-4 = 11
The answer is a = 4, b = 11
Answer:
The answer is a = 4, b = 11
Step-by-step explanation:
Now give that guy above brainliest!
Simplify the left side of the equation.
(x + 10) + (4y - x - 10) = 180°
4y = 180°
y= 45°
Combine like terms.
Divide both sides by 4.
Therefore, x = 14 and y = 45.
Now find the measure of each angle. First, find the measure of ZBMQ. To do so, substitute the
value of x into the expression (x + 10)° and simplify.
(x + 10) = (14+ 10) Substitute.
