Answer:
-6
Step-by-step explanation:
-3/2 x 4/1 = 12/2
Simply to -6/1 or -6
The required temperature would be -6°C at 4:00 pm, which is determined by the expression -3/2 × 4/1.
What is a numerical expression?A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.
At midday, the temperature is 0 degrees Celsius. For four hours, the temperature decreases by -3/2 degrees Celsius per hour.
According to the given condition, we can write the expression as:
⇒ -3/2 × 4/1
⇒ -12/2
Apply the division operation to get the solution
⇒ -6
So, the time at which the temperature goes -6°C is 4:00 PM.
Therefore, the required temperature would be -6°C at 4:00 pm.

4$ off every time because if you take 6×11 you get 66 from the total without anything off and then subtract 66-46 and you get 20 so you take 20÷ 5 because 1 round was his first and there was no discount on the first round so your answer is 4$ everytime
Lorraine writes the equation shown. x squared + y minus 15 = 0 She wants to describe the equation using the term relation and the term function. The equation represents .
Answer:
The equation represents: A relation and a function
Step-by-step explanation:
A function is said to be a relation; however, the relation does not have to function. For a relation to result in a function, then every input gives an important output. Thus; the given information x² + y - 15 = 0 can be re-written as:
y = - x² + 15
Similarly, the equation typically illustrates a relation as well. Consequently, suppose we replace any x-value for x, then the one possible output will be for y. Hence, that is also a function.

Hi im in 5th grade an I really need help on my math homework. The question is "Which decimal rounded to the nearest tenth is 0.9"? Please help me I would be very happy if you could. :) -Brooklyn
Answer:
0.85, 0.86, 0.87, 0.88 or 0.89
Step-by-step explanation:
This is because, to round up a number to the nearest, the number after that number must be greater than or equal to 5. So, any of 0.85, 0.86, 0.87, 0.88 or 0.89 can be rounded to the nearest tenth since the digit after the 8 is greater than or equal to 5. So, 0.85 rounds to 0.9 to the nearest tenth, 0.86 rounds to 0.9 to the nearest tenth, 0.87 rounds to 0.9 to the nearest tenth, 0.88 rounds to 0.9 to the nearest tenth and 0.89 rounds to 0.9 to the nearest tenth.
So, any of 0.85, 0.86, 0.87, 0.88 or 0.89 can be rounded to the nearest tenth is 0.9

A hockey player needs to shoot a puck 55 meters from his current location to his opponent's goal to score a goal. After the shot, the puck is 120 centimeters from his opponent's goal. If there are 100 centimeters in 1 meter, how many meters did the puck travel?
Answer:
The puck traveled a distance of 5.38 meters or 5,380 meters
Step-by-step explanation:
Here, we want to know the distance the puck traveled.
The distance from the player’s current location to the opponent’s is 55 meters
Since there are 100 centimeters in a meter, then
55 m= 55 * 100 = 5,500 centimeters
Now, we are told that the puck landed just 120 cm from the opponent’s goal
The distance traveled by the puck will be;
5,500 cm - 120 cm = 5,380 cm
The puck traveled a distance of 5,380 cm or 5.38 meters (5,380 cm to meters is calculated by just dividing by 100)

Simplify to get a quadratic equation.
Use the quadratic formula to find the values of x.
Step-by-step explanation:
The radical equation is expressed as:
[tex]\sqrt{x+3} - \sqrt{2x-1} = -2[/tex]
The following steps are to be followed to calculate x:
Step 1: Raise both sides of the equation to the power of 2.
[tex](\sqrt{x+3} - \sqrt{2x-1})^2 = (-2)^2\\x+3 - 2\sqrt{x+3}\sqrt{2x-1}+(2x-1) = 4\\ - 2\sqrt{x+3}\sqrt{2x-1}+x+3+2x-1 = 4\\ - 2\sqrt{x+3}\sqrt{2x-1}+3x+2 = 4\\ - 2\sqrt{x+3}\sqrt{2x-1} +3x-2 = 0\\[/tex]
Step 2: Raise both sides of the equation to the power of 2 again
[tex](-2\sqrt{x+3}\sqrt{2x-1})^2 = (2-3x)^2\\4(x+3)(2x-1) = (2-3x)^2\\[/tex]
Step 3: Simplify to get a quadratic equation.
[tex]\\4(2x^2-x+6x-3) = 4-12x+9x^2\\4(2x^2+5x-3) = 4-12x+9x^2\\8x^2+20x-12 = 4-12x+9x^2\\x^2-32x+16 = 0[/tex]
Step 4: Use the quadratic formula to find the values of x.
x = 32±√32²-4(16)/2

A principal evenly distributes 6 reams of copy paper to 8 fifth-grade teachers How many reams of paper does each fifth-grade teacher receive? b. If there were twice as many reams of paper and half as many teachers, how would the amount each teacher receives change?
Answer:
a. 0.75 reams
b. The amount of reams received by each teacher would increase by 2.25 reams.
Step-by-step explanation:
Total reams of copy paper = 6
Number of fifth-grade teachers = 8
a. Number of reams collected by each teacher = [tex]\frac{number of reams}{number of teachers}[/tex]
= [tex]\frac{6}{8}[/tex]
= [tex]\frac{3}{4}[/tex]
= 0.75 reams
b. Twice as many reams of paper = 2 x 6
= 12
Half as many teachers = [tex]\frac{1}{2}[/tex] x 8
= 4
Number of reams collected by each teacher = [tex]\frac{12}{4}[/tex]
= 3 reams
The amount of reams received by each teacher would increase by;
3 - [tex]\frac{3}{4}[/tex]
= [tex]\frac{12 - 3}{4}[/tex]
= [tex]\frac{9}{4}[/tex]
= 2.25 reams
The amount of reams received by each teacher would increase by 2.25 reams.

The population growth (in thousands) for Decatur can be represented by the expression 3x + 5 3 x + 261, where x represents the number of years since 2016. The population growth (in thousands) for neighboring Lithonia can be represented by the expression 4x - 5 2 x + 212, where x represents the numberof years since 2016. The governor of Georgia would like to know when the populations of the two towns will be equal.
Answer:
1967 or 2069
Step-by-step explanation:
To do this, you need to equal the expressions:
3x^2+53x+261=4x^2-52x+212
now, solve for y, when x=0:
-1(0)^2+53(0)+261=4(0)^2-52(0)+212
0+0+261=0-0+212
261=212
the difference is 49, so 49 years before or after 2016.
