Hence The product can also be expressed as fractions
615/100*(-311/100)
Answer:
(6 x (-3.11)) + (0.15 x (-3.11))
Step-by-step explanation:
In the given expression, the term 6.15 can be written as follows.
6.15 = 6 + 0.15
Apply the distributive property.
6.15 x (3.11) = (6 x (-3.11)) + (0.15 x (-3.11))
So, another method of computing the given product is given by the following expression.
6 x (-3.11)) + (0.15 x (-3.11))

Solve the equation:
|x+1|+|x−2|=3
The only solution to the equation |x+1|+|x-2|=3 is x=2. To find this, we broke the problem into cases based on the nature of absolute values and verified the solution by substitution.
To solve the equation |x+1|+|x-2|=3, we need to consider the different cases due to the absolute value functions.
If x = 2, both x+1 and x-2 are non-negative, and our equation simplifies to x+1+x-2=3, which results in x=2.
If -1 \\leq x < 2, x+1 is non-negative, and x-2 is negative, so the equation becomes x+1-(x-2)=3, which is an identity and does not yield a solution.
If x < -1, both x+1 and x-2 are negative, so the equation becomes -(x+1)-(-x+2)=3, simplifying down to -1=3, which is false and cannot be a solution.
Therefore, the only solution is x=2. We can verify this by substituting back into the original equation. This is consistent with the properties of absolute value equations. Always verify your solutions to ensure they hold in the original equation.

The Petersons hotel has a lazy river that is shaped like a circle with a diameter of 120 ft. If mr. Peterson has made one full rotation how many feet has he traveled?
Mr. Peterson has traveled approximately 376.8 feet after making one full rotation in a lazy river with a diameter of 120 feet, by calculating the circumference of the circle using the formula C = πd.
Explanation:The question asks how many feet Mr. Peterson has traveled after making one full rotation in a lazy river shaped like a circle with a diameter of 120 ft. To find the distance traveled, we need to calculate the circumference of the circle, which is the total distance around the circle.
The formula for the circumference of a circle is C = πd, where C is the circumference and d is the diameter of the circle. Using π approximately equal to 3.14 and the given diameter of 120 feet, we calculate the circumference as follows:
C = πd = 3.14 × 120 ft = 376.8 ft
Therefore, Mr. Peterson has traveled approximately 376.8 feet after making one full rotation around the lazy river.

Answer:
Perpendicular
Step-by-step explanation:
Parallel lines have equal slopes.
The product of perpendicular slopes = - 1
Calculate the slopes of u and v using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 51, 65) and (x₂, y₂ ) = (- 46, 96)
m = [tex]\frac{96-65}{-46+51}[/tex] = [tex]\frac{31}{5}[/tex]
Repeat with (x₁, y₁ ) = (- 37, 85) and (x₂, y₂ ) = (- 6, 80)
m = [tex]\frac{80-85}{-6+37}[/tex] = - [tex]\frac{5}{31}[/tex]
Since [tex]\frac{31}{5}[/tex] × - [tex]\frac{5}{31}[/tex] = - 1
Then the lines are Perpendicular

3( y + 4) = 24
Answer:
y = 4
Step-by-step explanation:
We have to use the distributive property. Remember that the distributive property states that when expanding out a parentheses, you must find the sum of the product of the "outside term" with each of the "inside terms".
In this case, the "outside term" is 3 and the "inside terms" are y and 4. So, we need to multiply 3 by each of y and 4 and then add those together:
3(y + 4) = 24
3 * y + 3 * 4 = 24
3y + 12 = 24
Now, we subtract 12 from both sides to isolate the variable:
3y + 12 - 12 = 24 - 12
3y = 12
Finally, divide by 3 from both sides to get y alone:
3y/3 = 12/3
y = 4
Thus, y = 4.
Hope this helps!
Answer:
y = 4
Step-by-step explanation:
3(y+4) = 24 <- This is a linear equation so its solved as such
3y+12 = 24 <- Distribute the (PEMDAS)
-12 -12 <- Get y alone
3y = 12 <- Rewrite with y alone
[tex]\frac{3y}{3}[/tex] = [tex]\frac{12}{3}[/tex] <- Divide both sides
y = 4
A drone is flown, with constant acceleration, in a horizontal plane.
When initially observed, at a point P, it has a velocity of (2i − 7j) ms−1
Four seconds later the drone is at a point Q and has a velocity of (14i + j) ms−1
(i) Find the acceleration of the drone in terms of i and j.
Answer:
3i + 2j
Step-by-step explanation:
Acceleration = change in velocity/time
Change in velocity
(14i + j) - (2i - 7j)
= 12i + 8j
Divide by time (t = 4)
3i + 2j
The acceleration of the drone in terms of i and j is 3i+2j.
What is the average acceleration?Acceleration is the amount by which the velocity of something changes over a set period of time.
The formula to find the acceleration is a=(v-v₀)/t, where a=average acceleration, v=final velocity, v₀=initial velocity and t=time.
Given that, a drone is flown, with constant acceleration, in a horizontal plane. When initially observed, at a point P, it has a velocity of (2i-7j) ms⁻¹.
Four seconds later the drone is at a point Q and has a velocity of (14i+j) ms⁻¹.
Acceleration = change in velocity/time
Change in velocity
(14i + j) - (2i - 7j)
= 12i + 8j
Divide by time (t = 4)
= 4(3i+2j)/4
= 3i+2j
Therefore, the acceleration of the drone in terms of i and j is 3i+2j.

Picture 1. Right angle
Sunrise Ah looks for side measure.
The number above is the hypotenuse
A/H = cos ( ) x hyp =base
A/H = cos ( ) x hyp = side
Picture 2.
Sunrise Soh looks for side measure.
The number above it is the hypotenuse
O/H = sin ( ) =p (for product) take the p x hyp.
Picture 3 Sunrise Toast (oa) looks for side measure = O/A
Tan ( lower angle ) x base = side
Picture 4
Side of car with window as hypotenuse.
Two wheels are the 2 angles given and the back seat is perpendicular to both wheels = so the triangle structure looks like this /00|7
so you type in 7/sin ( 1st wheel) x (2nd wheel) = hypotenuse.
Both angles given or worked out this is when this is used.
Picture 5
Electric mast looking for slope
SIN =S/P = O/A
Angle at top
We have the side at 70 and looking for the slope
Sin( top angle) = p then side/p = hyp
Picture 6
Top angle and base given creates a T this means half both of them before dividing.
Half = 1/2 base / sin (1/2) = hypotenuse
Picture 7
Top angle and base given creates a T this means half both of them before dividing.
To find height =
Half = 1/2 base /Tan 1/2) = Triangle height.
Key checker after pictures are drawn is;
sunrise = low angle x side or low angle x base = hypotenuse.
car = backseat x wheels = hypotenuse
Half = 1/2 base / sin (1/2) = hypotenuse
Half = 1/2 base / tan (1/2) = height
Just take care with top angle and lower angle key words in the drawing descriptions and then the pictures will help.
All 12 members of the glee club went to eat at the Hibachi Grill restaurant. The chicken costs $10 per person, while the beef costs $14 per person. At the end of the evening, the club members received a bill for $136, not including tax.
Assuming that each person ordered only one type of meal (chicken or beef), how many club members ordered chicken?
