Well since the value of C has been given to you, plug it into the equation.

F = 1.8(10) + 32
F = 18 +32
F = 50

The temperature in Fahrenheit would be 50 degrees.

Greetings!

To find the -10°C in Fahrenheit, you just need to input the information we have into the formula:

$F=1.8C+32$
Input.
$F=1.8(-10)+32$
Simplify.
$F=-18+32$
The Answer Is:
$F=14$

-10°C would be 14°F.

Hope this helps.

What is the perimeter of square PQRS?

Citrus2011 [14]

First, we need to find the length of the side of the square.
Use phytagorean theorem to find the length of the side. The side acts as hypotenuse, the distance of x and the distance of y acts as the perpendicular side of a right triangle. For clear understanding, see image attached.

General phytagorean theorem
c² = a² + b²
c represents hypotenuse, a and b are the side perpendicular to each other.

In this case, we could write it as
s² = Δx² + Δy²
s represents the length of the side, Δx represents distance of x, Δy represents distance of y

Plug in the numbers, use two of the vertices
I use (4,-1) and (7,3)
s² = Δx² + Δy²
s² = (7-4)² + (3 - (-1))²
s² = 3² + (3 + 1)²
s² = 3² + 4²
s² = 9 + 16
s² = 25
s = √25
s = 5
The length of the side is equal to 5 units length.

Second, find the area of the square
General area to find the area of a square
a = s²

Plug in the numbers
a = s²
a = 5²
a = 25
The area of the square is equal to 25 units area.

Find an ordered pair that satisfies both of the equations below.

liraira [26]

Answer: (x, y) = (2, 3)

This is the system of equations 2x - 3y = -5, 5x - 2y = 4. Multiply the first equation by 2 and the second equation by 3 to get 4x - 6y = -10, 15x - 6y = 12. Now we can use elimination: subtract the equations to get -11x = -22, so x = 2. 2x - 3y = 2(2) - 3y = 4 - 3y = -5, so 3y = 9 and y = 3. The solution is (2, 3).

i hope this helped! :D

3. The teacher asked the class, "How many tenths are equivalent to 37.6?" Student 1 answered, "37 tenths." Student 2 answered, "

Ksivusya [100]

Using proportions, it is found that Student 2 is correct, as 37.6/0.1 = 376.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

One tenth is worth 0.1. How many tenths are there in 37.6? The division is given as follows:

37.6/0.1 = 376.

Hence student 2 is correct, as there are 376 tenths in 37.6.

With the beam being held still at a height of 40 m, the crane breaks and the beam falls to the ground. Assuming no air resistanc

lapo4ka [179]

What we have so far:
Kinetic energy = 0. The reason behind that is because the beam is not moving at a height of 40m.
Gavity, g = 9.8m/s²
Height = 40m
Potential energy = mgh; this is equal to 0 because m, stands for mass and in this problem, we do not have a value for the mass of the beam. Hence, 0 x 9.8m/s² x 40m = 0. Potential energy = 0.

Solution:
We will use the equation of Total energy:
TE = potential energy + kinetic energy

TE = 0 + 0

∴ TE = 0

The answer is: Assuming no air resistance, the total energy of the beam as it hits the ground is 0.

A car traveled 300 meters in 30 seconds. A truck traveled 600 meters in 60 seconds. Which car was faster ?

rewona [7]

Multiply the car by 2: 300 meters x 2 = 600 meters

30 seconds x 2 = 60 seconds.

The car also traveled 600 meters in 60 seconds, so the speed of the vehicles are the same.

No vehicle was faster.
