andrew can paint a room in $3$ hours. bob can paint the same room in $6$ hours. how many hours will it take andrew and bob to paint the room together?
Answers
Total time taken by Andrew and bob is 2hr.
given, time taken by Andrew to paint the room = 3hrtime taken by bob to paint the room =6hr rate of Andrew as x =1/3.
rate of bob as y=1/6x+y=1/3+1/6=1/2
total time taken by Andrew and bob =1/x + y
=1/1/3+1/6
= 2hr.
therefore total time taken by Andrew and bob is 2 hr.
The formula for time is given as [Time = Distance ÷ Speed]. To calculate the distance, the time formula can be molded as [Distance = Speed × Time].
To get the total decimal hours we use the formula: h = hours + (minutes / 60) + (seconds / 3600). To get the total decimal minutes we use the formula: m = (hours * 60) + minutes + (seconds / 60).

In the trapezoid below, x = [? ]
Answers
if this trapezoid is to scale, then the scale factor between the shortest and longest side is 1.5
so, that means that 1.5(2x+6) = 4x+2
so, your equation becomes 3x+9 = 4x+2
if you subtract 2 from each side, you get 3x+7 = 4x
meaning that x = 7

Find the coordinates of the orthocenter of the triangle whose vertices are A(3, 1), B(0, 4) and C(-3, 1).
Answers
Let us consider the perpendicular drawn from A is AD and perpendicular drawn from the vertex B is BE.
Slope of AC = [(y2 - y1)/(x2 - x1)]
A (3, 1) and C (-3, 1)
here x1 = 3, x2 = -3, y1 = 1 and y2 = 1
= (1 - 1) / (-3 - 3)
= 0 / (-6)
= 0
Slope of the altitude BE = -1/ slope of AC
= -1/0
Equation of the altitude BE :
(y - y1) = m (x -x1)
Here B (0, 4) and m = -1/0
(y - 4) = -1/0 (x - 0)
10 (y - 4) = -1(x)
x + 10y - 40 = 0 --------(1)
Slope of BC = (y2 - y1)(x2 - x1)]
B (0, 4) and C (-3, 1)
Here x1 = 0, x2 = -3, y1 = 4 and y2 = 1.
= (1 - 4) / (-3 - 0)
= (-3)/(-3)
= 1
Slope of the altitude AD = -1/ slope of AC
= -1/1
= -1
Equation of the altitude AD :
(y - y1) = m (x - x1)
Here A(3, 1) m = -1
(y - 1) = -1 (x - 3)
(y - 1) = -x + 3
x + y - 1 - 3 = 0
x + y - 4 = 0
x = -y + 4--------(2)
Substituting (2) into (1), we get
-y + 4 + 10y - 40 = 0
9y - 36 = 0
y = 36/9
y = 4
By applying y = 4 in (1), we get
x = -4 + 4
x = 0

FIND THE UNIT RATE HELP ITS DUE IN 30 MINUTES
Answers
Answer:
The unit rate = 2 dollars / per pineapple
Point A(7, 14) indicates that the value of 14 pineapples is 7 dollars.
Step-by-step explanation:
The unit rate represents the slope of the line.
It means the slope is often termed as a ratio, which could be expressed as a unit rate found at the point on the graph with the given ordered pairs.
Let us take two points that lie on the graph to determine the unit rate (or slope)
(1, 2)(2, 4)unit rate = slope = y₂-y₁ / x₂-x₁
= 4-2 / 2-1
= 2/1
= 2
Thus, the unit rate = 2 dollars / per pineapple
The location of point A is (7, 14)
i.e. A(7, 14)
Point A(7, 14) indicates that the value of 14 pineapples is 7 dollars.4. Your Language Arts teacher expects

for each equation, find f(-x) and -f(x) and then determine whether if is even, odd or neither. Justify your answer
[tex]f(x)=x^4+4/x^2+1[/tex]
Answers
The function f(x) = x^4 + 4/x^2 + 1 is an even function
How to determine the function type?The equation of the function is given as
f(x) = x^4 + 4/x^2 + 1
Calculate f(-x)
So, we have
f(-x) = (-x)^4 + 4/(-x)^2 + 1
Evaluate the exponents
f(-x) = x^4 + 4/x^2 + 1
Calculate -f(x)
So, we have
-f(x) = -[x^4 + 4/x^2 + 1]
Evaluate the product
-f(x) = - x^4 + 4/x^2 + 1
From the above computations, we have
f(x) = f(-x)
This represents an even function
Hence, the function f(x) = x^4 + 4/x^2 + 1 is an even function

In the given figure , two sides of the triangle are equal , so it is isosceles triangle . So , as we know that in an isosceles triangle equal side's opposite answers are also equal . Now ,
=> x = 75°
Hence , x = 75°
Answer 2 :-Using the same property which we used in the above problem ,
• x = x
Now using angle sum property of triangle ,
=> x + x + 40° = 180°
=> 2x + 40° = 180°
=> 2x = 180° - 40°
=> 2x = 140°
=> x = 140° / 2
=> x = 70°
Hence , x = 70° .
Answer:
The ans to the first question would be 75, Coz....
It's an Isosclese triangle, as both sides are equal [The two lines on the triangle indicate that its equal]
So,the angle given is 75 degrees, the other angle would be 75 degrees too.
For the second question-
The same rule applies here, the triangle shown is an isosclese triangle,so the angle x & the angle opposite to x should be equal [The angle opposite or next to angle x is blank, so lets just call it y]
The equation of a triangle goes-
The angles of a triangle add upto 180
So 40+x+y=180
180-40 will give the sum of both angle x & y
180-40=140 [Now we know that x+y=140, we also know that both angles have the same value, so basically they're equal]
this means that we can divide 140 equally into two parts to disturbute the value to both x & y
140/2=70 degrees
So, the ans of x=70 [y is also 70, but the question doesnt ask for it]

Answer:
The most common interval is 10 to 14.99 $ with 11 items
Step-by-step explanation:
See attached for details.
$10.00-$14.99 is the most common interval of dinner prices.
To find the most common interval of dinner prices,
Organize the data into the specified intervals and then count the occurrences in each interval.
Here are the intervals:
1. $5.00-$9.99
2. $10.00-$14.99
3. $15.00-$19.99
4. $20.00-$24.99
5. $25 and up
Now, let's categorize the dinner prices from the given list into these intervals:
1. $7.50, $7.98, $6.50, $8.25, $8.75, $9.00, $9.99 (7 prices)
2. $10.00, $12.00, $12.98, $12.99, $11.50, $13.50, $11.25, $13.00, $12.50 (9 prices)
3. $14.00, $14.75, $15.00, $17.49, $16.00, $17.99 (6 prices)
4. $21.00, $20.00, $22.00 (3 prices)
5. $26.00, $28.50, $25 and up (3 prices)
Now, let's see which interval has the highest number of prices.
It appears that the second interval, $10.00-$14.99, has the most prices (9 prices), making it the most common interval of dinner prices.
Hence, $10.00-$14.99 is the most common interval of dinner prices.

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about how probable an event is to happen, or its chance of happening.( -8 ) + 0 + ( - 6) + 2 + ( -4 ) + ( -2 ) = -20 + 2 = -18

Answer:
18 cm
Step-by-step explanation:
Consider right triangle PCA.
The length PC is the hypotenuse of that triangle. It is also the radius of the circle: 15 cm.
The length AC is AB -CB = (27 -15) cm = 12 cm.
The length AP can be found from the Pythagorean theorem:
AP² +AC² = PC²
AP² = PC² -AC² = (15 cm)² -(12 cm)² = (225 -144) cm² = 81 cm²
AP = √(81 cm²) = 9 cm
Since A is the midpoint of PQ, the length of PQ is double the length of AP:
PQ = 2·AP = 2·9 cm
PQ = 18 cm
