Answer:
5 seconds.
Step-by-step explanation:
Make an equation.
Time in air = x
Time in water = 12 - x
16x + 36 - 3x = 127
13x = 91
x = 7
12 - 7 = 5

Which statement must always be true?
1) ZBAC & ZBOC
2) MZBAC -
3) ABAC and ABOC are isosceles.
4) The area of ABAC is twice the area
of ABOC.
m_BOC
Answer:
It would be number 2. measure of angle BAC is equal to half the measure of angle BOC.
Step-by-step explanation:
This is because of inscribed angles.
In the diagram below of circle O, OB and OC are radii, and chords AB, BC, and AC are drawn. The correct statement is B. m < BAC = 1/2 m < BOC.
How to explain the circle?From the information given, (a + b) + (a + c) + (b + c) = 180°
2a + 2b + 2c = 180°
2a + 2b = 180° - 2c
2(a + b) = 180° - 2c
Therefore, m < BAC = 1/2 m < BOC.
In conclusion, the correct option is B.

Find the obsolete value
l-9l 2. l64l 3. l-22l
Answer:
see below
Step-by-step explanation:
The absolute value means take the non negative value
l-9l = 9
l64l =64
l-22l=22
Answer:
1. 9 2. 64 3. 22
Step-by-step explanation:
The obsolute value is how far away the number is from zero
For example:
I-94I is 94
but
-I94I is -94
if the negative is outside the equation then its a negative
A used car dealer prices her cars so that she makes a minimum profit of 15% on each car sold. If she acquired a car for $4,500, which inequality can be used to determine the acceptable selling prices, p, of that car? 1.15 p less-than-or-equal-to 4,500 1.15 p greater-than-or-equal-to 4,500 p less-than-or-equal-to 1.15 (4,500) p greater-than-or-equal-to 1.15 (4,500)
Answer:
[tex]p\geq 1.15(4,500)[/tex]
Step-by-step explanation:
If she makes a minimum profit, we need to use the symbol [tex]\geq[/tex], which indicates minimum quality.
Let's call [tex]p[/tex] profit, so the inequality which represent this problem would be
[tex]p\geq 1.15(4,500)[/tex]
The price of the car is multiplied by 1.15, because she must add her profit comission which is 0.15 or 15%.
Therefore, the right answer is the last choice.

A jacket usually sells for $57.00. If the jacket is 40% off, and sales tax is 5%, what is the total price of the jacket, including tax?
Answer: $35.91
Step-by-step explanation:
Since the jacket is 40% off, we multiply the original price by 60% to get the price remaining. ($57 x 0.6 = $34.20)
Then, we multiply the new price by 105% (includes the 5% sales tax) to get the total price. ($34.20 x 1.05 = $35.91)

The table shows Peter's net worth statement. Assets are shown as positive numbers, and liabilities are shown as negative numbers. The value of Peter's house is not given. Peter's net worth is $101,800. Based on the information in the table, what is the current value of Peter's house?
Answer:
Value of House = $98000
Step-by-step explanation:
The sum of all of the assets and liabilities + value of the house = $101,800
Value of House + $900 - $3400 + $16900 - $16300 + $4500 + $1200 = $101,800
=> Value of House + $3800 = $101,800
=> Value of House = $101,800 - $3800
=> Value of House = $98000
The current value of Peter's house will be $98000.
A table is given which shows Peter's net worth and assets are shown as positive numbers, and liabilities are shown as negative numbers.
We have to find out the current value of Peter's house if , Peter's net worth is $101,800.
What will be the resulting value ; 35 - 10 - 5 + 10 = ?
The resulting value will be 30.
As per the question ;
The sum of all of the assets and liabilities plus value of the house is equal to $101,800.
Assume value of house = x
⇒ x + $900 - $3400 + $16900 - $16300 + $4500 + $1200 = $101,800
⇒ x + $3800 = $101,800
⇒ x = $101,800 - $3800
⇒ x = $98000
Thus , the current value of Peter's house will be $98000.

[tex]x + 50.75\geq \frac{387}{4} \\\\x\geq \frac{387}{4} -50.75\\subtract \\x\geq \frac{387}{4} - \frac{203}{4} \\solution:\\x\geq 46\\\\\\[/tex]
The answer is: C
Answer:
Yes your answer is c
Step-by-step explanation:
First convert to mixed fraction.
X + 50.75 > 387 / 4
Then subtract 50.75 from both sides
X + 50.75 - 50.75 > 387 / 4 - 50.75
Finally simplify,
X > 46

You pick a card at random. Without putting the first card back, you pick a second card at random.
What is the probability of picking a 3 and then picking a 3?
Simplify your answer and write it as a fraction or whole number.
Answer:
You have three card : 3, 4, 5 and 6.
You first pick one card randomly, the probability of picking a 3 is:
P = 1/4
You then pick a second card without putting the first card back, the probability of picking a 3 is:
P = 1/3
=> The probability of picking a 3 and then picking a 3:
P = (1/4) x (1/3) = 1/12
