How do you find mass using FG?
To find the mass of an object, one can use the formula (Force x Distance) / Gravitational Constant (FG). This formula involves multiplying the force applied to an object by the distance it moves, and then dividing the result by the gravitational constant (FG). The resulting number is the mass of the object in kilograms.
Mass can be found by using the formula (Force x Distance) / Gravitational Constant (FG).
For example, if a force of 10N is applied to an object that is moving 2 meters, the mass of the object can be calculated as follows:
Mass = (10 N x 2 m) / FG
Mass = 20 / 9.8
Mass = 2.04 kg
Finding mass using the force-distance formula (FG) is a simple process. To use it, one needs to know the force applied to an object, the distance it moves, and the gravitational constant (FG). The force and distance values can be measured or calculated depending on the situation. The gravitational constant is a fixed number and is equal to 9.8 m/s2. To calculate the mass, one needs to take the force multiplied by the distance and then divide it by the gravitational constant (FG). The resulting number is the mass of the object in kilograms. This formula is useful for calculating the mass of objects in a variety of situations. It is also useful for verifying the mass of an object that has already been measured.

How do you graph the equation y = 1x / 2 + (-5)
To graph the equation y = 1x / 2 + (-5), you will need to plot several points that satisfy the equation and then connect them with a line.
To do this, you can pick a few values of x, substitute them into the equation to find the corresponding values of y, and then plot these points on the coordinate plane.
For example, if you choose x = -2, the corresponding value of y is (-2) * (1 / 2) + (-5) = -5.5. If you choose x = 0, the corresponding value of y is (0) * (1 / 2) + (-5) = -5. And if you choose x = 2, the corresponding value of y is (2) * (1 / 2) + (-5) = -4.
You can then plot these points on the coordinate plane and connect them with a line to graph the equation.

Step-by-step explanation:
A boat is traveling due east for 130 miles. The boat travels another 72 miles at a bearing N38E. Determine the distance, direction angle, and bearing of the boat from its original location.
The distance and bearing of the boat from its original location are about 183.33 miles, N71.97°E
What is the bearing of a location?A bearing is a description of the amount by which a north or south headed line is deflected in the eastern or western direction.
The initial direction in which the boat is traveling = Due east
The distance the boat travels in the direction due east = 130 miles
The distance the boat travels in the direction N38°E = 72 miles
Therefore;
The distance the boat has traveled from its original location is found using the law of cosines as follows;
The included angle between the 130 miles distance the boat travels east and the 72 miles distance the boat travels N38°E = 90° + 38° = 128°
Let d represent the distance of the boat from its original location, we get;
d² = 130² + 72² - 2 × 130 × 72 × cos(128°) ≈ 33609.1828181
d ≈ √(33609.1828181) ≈ 183.33
The distance of the boat from its original location is about 183.33 miles
Let the angle formed by the direction of the boat to its destination and the path the boat travels east, according to the law of sines, we get;
183.33/(sin(128°) ≈ 72/(sin(B))
(sin(B)) ≈ 72 × (sin(128°))/183.33
m∠B ≈ arcsin(72 × (sin(128°))/183.33) ≈ 18.03°
The bearing of the boat from its original location is; N(90° - 18.03°)E = N71.97°E

There are 45 coins consisting of nickels and dimes. If the total value of the coins is $3.75, how many nickels are there?
A 10
B 12
C 15
D 22
Answer:
15 nickels
Step-by-step explanation:
Choose variables: n = number of nickels, d = number of dimes.
There are two pieces of information given:
There are 45 coins, so n + d = 45.
The total value is $3.75 (let's use cents in order to avoid decimals), so
5n + 10d = 375
Solve the first equation for d by subtracting n from both sides.
d = 45 - d
Substitute this expression for d in the value equation:
5n + 10(45 - n) = 375 See? The only variable is now n!
Distribute the 10 (multiply).
5n + 450 - 10n = 375
450 - 5n = 375
-5n = -75
n = 15
There are 15 nickels.

4. Write an equation of the circle that has a diameter with endpoints (12, 3) and
(-18, 3). (Lesson 6-4)
x² + y² + 6x - 6y - 207 = 0 is the equation for the circle whose circumference has endpoints at (12, 3), and (-18, 3).
What is the equation of a circle?We are aware that a circle's general equation is (x - h)2 + (y - k)2 = r2, where (h, k) is its center and r is its radius.
Therefore, to bring the constant term to the righthand side of the equation, add 21 to both sides.
So, the midpoints of the diameter are determined by the coordinates of the circle's center since the endpoints of the diameter are (x1, y1) = (12,3) and (x2, y2) = (-18,3).
The midpoints are so:
x = (x₁ + x₂)/2 = (12 + (-18))/2 = (12 - 18)/2 = -6/2 = -3 and
y = (y₁ + y₂)/2 = (3 + 3)/2 = 6/2 = 3.
Consequently, the circle's center's coordinates are (-3, 3)
The circle's diameter:
The circle's radius is [(x1 - h)2 + (y1 - k)2], where:
(x₁, y₁) = coordinates of end of diameter = (12, 3) and
(h, k) = coordinates of center of circle = (-3, 3)
As a result, when we enter the values of the variables into r, we get:
r = √[(x₁ - h)² + (y₁ - k)²]
r = √[(12 - (-3))² + (3 - 3)²]
r = √[(12 + 3)² + 0²]
r = √[15² + 0²]
r = √15²
r = 15
The formula for the circle:
The formula for a circle with a center (h,k) is: (x - h)² + (y - k)² = r²
By changing the variables' values in the equation, we arrive at:
(x - h)² + (y - k)² = r²
(x - (-3))² + (y - 3)² = 15²
(x + 3)² + (y - 3)² = 15²
x² + 6x + 9 + y² - 6y + 9 = 225
x² + 6x + y² - 6y + 9 + 9 - 225 = 0
x² + y² + 6x - 6y - 207 = 0
Therefore, x² + y² + 6x - 6y - 207 = 0 is the equation for the circle whose circumference has endpoints at (12, 3), and (-18, 3).

Alex has five cups of strawberries. He wants to use 1 3/4 cups of strawberries for a fruit salad and 3 1/2 cups for jam. Does Alex have enough strawberries to make both recipes? Solve this problem any way you choose. Grade 5
Alex has five cups of strawberries and wants to use 1 3/4 cups of strawberries for a fruit salad and 3 1/2 cups for jam. Alex has enough strawberries to make both recipes.
To check if Alex has enough strawberries, we add the amount of strawberries needed for the fruit salad (1 3/4 cups) and the amount needed for the jam (3 1/2 cups)
1 3/4 cups + 3 1/5 cups
= 1 + 3/4 + 3 + 1/5
Multiplying 3/4 with 5/5 and 1/5 with 4/4 to make denominator equal
= 1 + 15/20 + 3 + 4/20
= 4 + 19/20
= 4 19/20 cups
4 19/20 is less than 5 cups. So Alex has enough strawberries for both recipes.

What should be added to XXYY to obtain 2x² 3xy?
(a) x² + 2xy - y² must be added to x² + xy + y² to get 2x² + 3xy. (b) 5a + b -6 must be subtracted from 2a + 8b + 10 to get -3a + 7b + 16.
a)
Here we are given the expression x² + xy + y²
Now we need to add something so that this expression becomes x² + 3xy
Let the expression to be added be p.
Hence we get
x² + xy + y² + p = 2x² + 3xy
or, p = 2x² + 3xy - (x² + xy + y²)
or, p = 2x² + 3xy - x² - xy - y²
or, p = x² + 2xy - y²
Hence, x² + 2xy - y² must be added.
b)
Here we are given the expression 2a + 8b + 10
We need to subtract another expression to get -3a + 7b + 16
Let the expression be t. Hence we get
2a + 8b + 10 - t = -3a + 7b + 16
or, t = 2a + 8b + 10 - (-3a + 7b + 16)
or, t = 2a + 8b + 10 + 3a - 7b - 16
or, t = 5a + b - 6
Hence 5a + b - 6 must be subtracted,
