Wayne has a recipe that says to heat the oven to 160°C. Wayne evaluates the expression 1.8C + 32 when C= 160 to convert the temperature to degrees Fahrenheit To which temperature should Wayne heat the oven?
Wayne should heat the oven to a temperature of 320°F for a recipe.
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers. Unknown variables, numbers, and arithmetic operators make up an algebraic expression.
Wayne has a recipe that says to heat the oven to 160°C.
To convert a temperature in degrees Celsius to degrees Fahrenheit, we can use the formula:
F = 1.8C + 32
Given that C= 160, we can substitute it into the formula:
F = 1.8(160) + 32
F = 288 + 32
F = 320
Therefore, he should heat the oven to 320°F.

How are slope and speed related?
Answer:
you will get speed on a slope and you will get speed with speed (:
Step-by-step explanation:
Answer:
The joint dependence of locomotive power on speed and slope is crucial in the non-stationary conditions where the skier passes high and low points along the track where both speed and slope change rapidly.
Step-by-step explanation:
Hope this helps you and also when your going down a slope there is movement which in this case you will pick up speed. If your trying to go up a slope your not going to move as fast rather slow.

systems of equations 5x+y=7
20x+2=y
Step-by-step explanation:
5x+y=7
20x+2=y
put y value in first equation
5x+(20x+2)=7
25x=5
x=5
now put x value to determine y
as we know 20x+2=y
20(5)+2=y
y=102
Use the equation below to find v, if u = 18, a=6, and t=4.
v=u+at
Answer:
v= 42
Step-by-step explanation:
To find the value of v, substitute the given values into the equation.
v= u +at
when u= 18, a= 6, t= 4,
v= 18 +6(4)
v= 18 +24
v= 42

Which equation best describes the graph?
y = -4/5x – 2
y = 5/4x – 2
y = 4/5x + 2
y = -5/4x + 2
Answer:
A
Step-by-step explanation:
graph calc
Answer:
y=-4/5x-2
Step-by-step explanation:
the y intercept is -2, because the line touches the y axis at -2. the line is the the 2nd and the 4th quadrant which make the slope negative. The rise is 4 and the run is 5, so its -4/5x.

HELPPPP indentify one characteristic of exponential decay
Answer:
A more intuitive characteristic of exponential decay for many people is the time required for the decaying quantity to fall to one half of its initial value. This time is called the half-life, and often denoted by the symbol t1/2. The half-life can be written in terms of the decay constant, or the mean lifetime.

May anyone help me with question 3 please, I’m struggling at it
A) there is 5 blue marbles out of 20 total marbles.
The probability of picking blue would be number of blue/ total marbles = 5/20 which can be reduced to 1/4
The answer is 1/4
B) the more marbles of a color would be a greater chance of picking it.
Green has the highest number of marbles so the answer is green.
ChallengeThe price of Stock A at 9 AM Was $15.11. Since then, the price has been increasing at the
rate of $0.12 each hour. At noon the price of Stock B was $15.86. It begins to decrease at the rate of
$0.11 each hour. If the two rates continue, in how many hours will the prices of the two stocks be the
same?
In about hours, the prices of the two stocks will be the same.
(Round to the nearest tenth as needed
Answer:
Step-by-step explanation:
The information gives the Slope and y intercept of the line for stock A. At 9am, time = 0, the stock price is $15.11, the y intercept or b. The Slope of the line is 12 cents per hour, it is a positive Slope so it will rise from left to right.
The line in Slope form is
y= 0.12x+15.11
Stock B at noon, so 3 hours later, is $15.86 and is decreasing at a rate of 11 cents per hour.
We know the Slope is -0.11 and we know a point on its line is (3,15.86). From this we can solve for the y intercept by substituting the x and y values from the coordinate into the Slope equation.
15.86 = -0.11(3) + b
15.86 = -0.33 + b
Add 0.33 to both sides
16.19 = b so the equation of the line of stock B is y= - 0.11x + 16.19
Since we have two equations solved for y, we can set them equal to each other and solve for x
0.12x + 15.11 = - 0.11x + 16.19 add 0.11x - 15.11 to both sides
0.23x = 1.08 divide both sides by 0.23 to solve
x = 4.69565 to the nearest tenth 4.7 hours after 9am the two stocks will be the same price.

QUESTION 2
Angle J is (7x+2) Angle L is (25x-14)
What is (x)
Answer:Can u sum it up?
Step-by-step explanation:
Answer:
47
Step-by-step explanation:
Step-by-step explanation:
(Base1 + Base2)/2 = midsegment
1. ((2x+15) + (6x-37))/2 = 3x+5
2. (8X-22)/2 = 3x+5
3. ((8x-22)/2))2 = (3x+5)2
4. 8x-22=6x+10
5. 2x-22=10
6. 2x-22+22=10+22
7. 2x=32
8. x=16
Now that you have solved for X add the value to line RS
RS = 2(16) + 15
RS = 32 + 15
RS = 47

Answer:
Option D: Multiply the second equation by 4 and then add the result to the first equation is the correct answer.
Step-by-step explanation:
Given that:
x-4y = 2
2x+y = 12
For elimination, one of the variable is eliminated.
In this system,
we can either multiplying the first equation by 2 or second equation by 4.
Then we can add the equations.
By multiplying the second equation with 4 and then adding both equations, we can eliminate the variable y.
4(2x+y=12)
8x+4y=48
By adding
(x-4y)+(8x+4y)=2+48
7x=48
Hence,
Option D: Multiply the second equation by 4 and then add the result to the first equation is the correct answer.
