sally can paint a room in 3 hours while it takes steve 8 hours to paint the same room. how long would it take them to paint the room if they worked together ?
Answer:
2 hours 11 minutes
Step-by-step explanation:
Each hour Sally can paint 1/3 rooms, Steve can paint 1/8 rooms.
If they work together, each hour they can paint 1/3 + 1/8 = 11/24 rooms.
So They will take 1/(11/24) = 24/11 = 2.18 hours to paint a whole room.
2.18 hours = 2 hours 0.18*60 minutes
0.18 * 60 = 11
Answer: 2 hours 11 minutes

Answer:
tan²Θ
Step-by-step explanation:
simplify the expression using the identities
secΘ = [tex]\frac{1}{cos0}[/tex]
tan²Θ = sec²Θ - 1
then
[tex]\frac{cos0-cos^30}{cos^30}[/tex] ( divide each term on the numerator by cos³Θ
= [tex]\frac{cos0}{cos^30}[/tex] - [tex]\frac{cos^30}{cos^30}[/tex]
= [tex]\frac{1}{cos^20}[/tex] - 1
= sec²Θ - 1
= tan²Θ
Answer:

What is the equation for the graph shown?
Answer:
the first one is the answer
what is the slope-intercept equation for this line?
y=-3x + 4
Slope intercept form is y=mx+b
m = slope
b = y-intercept
If you look on the graph, you can see that 4 is the point in which it is intercepted on the y-axis, so that is the y-intercept. This means that b is 4.
b=4
y=-3x+4

One of the goats on Diane's farm is sick and has a high fever. Over the course of 4 hours, its
temperature changes by-2.8°F. Diane wants to know the average change in the goat's
temperature per hour.
• Write an expression for the average change in the goat's temperature each hour.
- 2.8
4
Answer:
-2.8 / 4
Step-by-step explanation:
The equivalent expression for the change in the goat's temperature each hour is A = -0.7°F/hour
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let's say the initial temperature of the goat was T1, and the final temperature after 4 hours was T2.
Now , the total change in temperature over the 4 hours is:
T2 - T1 = -2.8°F
The average change in temperature per hour can be expressed as:
The average change in temperature per hour = total change in temperature / number of hours
The average change in temperature per hour = (-2.8°F) / 4 hours
On simplifying the equation , we get
The average change in temperature per hour = -0.7°F/hour
Hence , the expression for the average change in the goat's temperature each hour is A = -0.7°F/hour

How do you solve 19/24=-5/6x-1/4 step by step, with verification?
Answer:
−1.25 or -5/4
Step-by-step explanation:
Equation
19/24 = -5/6x - 1/4
first swap sides so that all variable terms are on the left hand side
-5/6x - 1/4 = 19/24
add 1/4 to both sides.
-5/6x = 19/24 + 1/4
Least common multiple of 24 and 4 is 24. Convert 19/24 and 1/4 to fractions with a denominator of 24.
-5/6x = 19/24 + 6/24
Since 19/24 and 6/24 have the same denominator, add them by adding their numerators.
-5/6x = 19+6/24
Add 19 and 6 to get 25
-5/6x = 25/24
Multiply both sides by -6/5, the reciprocal of -5/6
x = 25/24 (-6/5)
Multiply 25/24 times -6/5 by multiplying numerator times numerator and denominator times denominator.
x = 25(-6) / 24x5
Do the multiplications in the fraction 25(-6) / 24x5
x = -150/120
Reduce the fraction -150/120 to the lowest terms by extracting and canceling out 30
x = -5/4
With verification
First write the equation and our value for x
19/24 = -5/6x - 1/4
x = -5/4
swap sides so that all variable terms are on the left hand side
-5/6x - 1/4 = 19/24
convert -5/6x to have the same denominator of 19/24.
-5 (4)
-6 (4)
== -20/24x
write the full equation with the converted variable
-20/24x - 1/4 = 19/24
Convert 1/4 to have the same denominator of 19/24
1 (6)
4 (6)
== 6/24
write the full equation with the converted variable and retain the minus sign
-20/24x - 6/24 = 19/24
write our value of X
-5/4
convert x to have the same denominator of -20/24x
-5(6)
-4(6)
= -30/24
x = -30/24
replace x in -20/24x with our updated value of x
-20/24(-30/24)
Multiply -20/24 by -30/24
= 25/24
write the full equation
25/24 - 6/24 = 19/24
subtract 25/24 by 6/24
19/24 = 19/24
the fraction 19/24 is equal to 19/24

6x+y = 4x+11y, isolate y terms on one side and x terms on another side by subtract 11y to both sides and subtract 6x to both sides
y -11y = 4x -6x, combine like terms
-10y = -2x , divide both sides by -10
y = (-2/-10)x, simplify the fraction

A rectangle's length and width are in a ratio of 20:3. The area is 240 square centimeters. What are the length and width?
Answer: Length - 40 cm, Width - 6cm
Step-by-step explanation:
Let the length of the rectangle = 20x.
Then, the width of the rectangle must = 3x by the ratio given.
The area of a rectangle is the length*width, which we are given as 240.
Therefore, 20x*3x = 240
We can combine like terms:
60x^2 = 240
Divide both sides by 60:
x^2 = 4
Square root both sides:
x = ± 2.
Since the sides of a rectangle cannot be negative, x must equal to 2.
The length of the rectangle is 20x, which is 20*2 = 40.
The width of the rectangle is 3x, which is 3*2 = 6.
Find the area of the shaded region. The length of AC is 10 meters and the m angle CAD=140 degrees . Round your answer to the nearest tenth (don't include units).
Answer:
122 m²
Step-by-step explanation:
Radius r = 10 m.
For a whole circle, the area is πr², that is for 360° at the center.
Now the angle is 140°, so the area of the shaded region is (140/360) πr² = 140 * 3.14 * 100/360 = 122 m²
Which graph represents the polar curve r = 1 + sin(θ)?
Answer:
I believe answer would be B
Step-by-step explanation:
I put the equation into desmos and B looks like the answer.
The graph of the polar curve r = 1 + sinФ is shown.
What is polar curve?A form created using the polar coordinate system is called a polar curve. Points on polar curves have varying distances from the origin (the pole), depending on the angle taken off the positive x-axis to calculate distance.
What is the graph?The graph is a demonstration of curves that gives the relationship between the x and y-axis.
Here,
r = 1 + sin(θ)
Using formula ,
r = a±bsinФ
Where,
a > 0 and b >0
and a = b
graph the cardioid.
r = 1 - sinФ
Thus, the graph of the polar curve r = 1 + sinФ is shown.
