if a movie starts
at 7:45 and is
I hour and 43
mins what time
will it end
9:28 would be the time the movie ends
Answer:
9:28
Step-by-step explanation:
First, add an hour to 7:45. Then, find how much time there is until you reach the next hour. After that, take the remaining time and add it on. 7:45 plus one hour is 8:45. There is fifteen minutes until the next hour, so subtract that from the forty three minutes. Add that fifteen minutes on and you are at nine o'clock. There is twenty eight minutes left. Add it in to nine o'clock. You now have the time the movie will end

rhombus
Not all rhombus can be inscribed in a circle until the rhombus has four 90º angles which is a square.
A rhombus can only be can be inscribed in a circle. basically the opposite angles there in the rhombus are congruent. if the opposite angles are not supplementary, that rhombus cannot be encircled, while that rhombus had four 90º angles, which means if it is a square, as in general a rhombus has two diagonals that are not equal except square so the endpoints of the shorter diagonal would not be points on the circle.

3 times a number is increased by 22, the result is 14 less than 7 times the number. What
is the number?
The value of the number is 9
Solving linear equationsFrom the question, we are to determine the number
From the given information,
"3 times a number is increased by 22"
Let the number be x
Thus,
3x + 22
"the result is 14 less than 7 times the number"
That is,
3x + 22 = 7x - 14
Now, solve the equation
3x + 22 = 7x - 14
22 + 14 = 7x - 3x
36 = 4x
x = 36/4
x = 9

Point D is located on line MV. The coordinates of D are (0,−3/4). What ratio relates MD to DV?
If you do solve this can you show your work so I know how to solve problems like this, too?
Point M coordinates: (-6, 3)
Point V coordinates: (2, -2)
If point D is located on the line MV, then the ratio that relates MD to DV is 3 : 1
How to determine the ratio that relates MD to DV?The given parameters are
Point M coordinates: (-6, 3)Point V coordinates: (2, -2)Point D coordinates: (0, -3/4)Calculate the distance between point D and point M using
d = √(x2 - x1)^2 + (y2 - y1)^2
So, we have
MD = √(-6 - 0)^2 + (3 + 3/4)^2
Calculate the distance between point D and point V using
d = √(x2 - x1)^2 + (y2 - y1)^2
So, we have
DV = √(2 - 0)^2 + (-2 + 3/4)^2
The ratio that relates MD to DV is represented as
Ratio = MD : DV
So, we have
MD : DV = √(-6 - 0)^2 + (3 + 3/4)^2 : √(2 - 0)^2 + (-2 + 3/4)^2
This gives
MD : DV = √(-6)^2 + (3 3/4)^2 : √(2)^2 + (-1 1/4)^2
Evaluate the exponents
MD : DV = √[36 + 225/16] : √[4 + 25/16]
Evaluate the sum
MD : DV = √[801/16] : √[89/16]
Divide ratios by √[89/16]
MD : DV = √9 : √1
Evaluate the exponent
MD : DV = 3 : 1
Hence, the ratio that relates MD to DV is 3 : 1

X=2 if and only if |x| = 2
True or false? Please answer if you're 100 percent sure.
Answer:
False
Step-by-step explanation:
Let's just analyze it.
x=2 if and only if |x|=2
That can be rewritten as:
if x = 2 then |x| = 2
AND
if |x| = 2 then x = 2
Let's solve each one separately:
we have x = 2
we can simply get |x| by removing the sign, if any. There is none, so |x| = 2.
The first part checks out.
we have |x| = 2
As with absolute values, this means that either x = 2 or x = -2
So we know from |x| that x is either 2 or -2, but the logical statement said "if |x| = 2 then x = 2", which is too specific - it forgets about -2.
The second part is false.
Overall, we now know that "X=2 if and only if |x| = 2" is false because x = -2 is a counterexample. We get: "False if and only if True" which itself is false.

Ricardo is talking to his parents about saving for retirement. Which of the following is NOT a good way to save for retirement, and why?
Answer:
There is nothing to refer to
Step-by-step explanation:
Write each statement in if-then form. An acute angle measures less than 90 .
If-then form of the given statement : an acute angle measures less than 90 will be : If an angle is an acute angle, then the angle measures less than 90 degrees.
We can understand this problem by using the above statement as an example like :
If an angle is an acute angle, then the angle measures less than 90 degrees. The part after if : an angle is an acute angle is called a hypotheses and the part after then : the angle measures less than 90 degrees is called a conclusion.
Hypotheses followed by a conclusion is called an If-then statement or a conditional statement.
This is noted as :
p → q
This is read - if p then q.
A conditional statement is false if hypothesis is true and the conclusion is false. The example above would be false if it said "If an angle is an acute angle, then the angle does not measure less than 90 degrees."

Solve each inequality. Check your solution. 4x - 2 > 1/2
The inequality given by 4x - 2 > 1/2 has the solution x > 5/8 or (5/8 , +∞).
Inequality refers to the relationship between two non-equal expressions. It can be denoted by > for greater than, < for less than, >/= for greater than and equal to, and </= for less than and equal to.
To solve an inequality is to find the values of x such that when we substitute that number for x we have a true statement.
Given the inequality 4x - 2 > 1/2, add 2 to both sides.
4x - 2 + 2 > 1/2 + 2
4x > 5/2
Multiply both sides by 1/4.
1/4(4x) > 1/4(5/2)
x > 5/8
To check, let x = 3/4
x = 3/4 ≥ 5/8
Substitute this value to the inequality.

Using the segment addition postulate, the values are:
a. y = 6
b. RS = 50
ST = 29
How to Apply the Segment Addition Postulate?Based on the segment addition postulate, the following equation is true which we can use in finding the missing measures:
RS + ST = RT.
Given:
RS = 8y + 2,
ST = 4y + 5,
RT = 79.
a. Plug in the given values into RS + ST = RT:
8y + 2 + 4y + 5 = 79
12y + 7 = 79
12y = 79 - 7
12y = 72
y = 6
b. RS = 8y + 2 = 8(6) + 2
RS = 50
ST = 4y + 5 = 4(6) + 5
ST = 29

deducted from his pay per week for Medicare, which is taxed at 1.45 percent?
According to the given statement;
Amount is deducted from his pay per week for Medicare, which is taxed at 1.45 percent is $8.35
What is gross pay?Gross pay is the sum of a person's earnings during a specific time period before any deductions are made. The calculation of gross pay does not take into account deductions for employer-provided health insurance, retirement plans, or compulsory taxes and Medicare contributions. Since it does not reflect a person's take-home pay, the gross pay definition is different from the one for net pay.
According to the given value;
Dalton's gross pay = 576
his medicare tax rate = 1.45% = 0.0145
the tax on his medicare = 0.0145 x 576 = $8.35
