The forces result in a right triangle. To obtain the resultant force, one can simply use the Pythagorean theorem. 1250 lbf and 2650 lbf both act as the legs of the triangle. Obtaining the hypotenuse via the theorem would yield the resultant force. This is done below:
c^2 = a^2 + b^2
c^2 = (1250)^2 + (2650)^2
c = 2930.017 lbf
Therefore, the magnitude of the resultant force is approximately equal to 2930 lbf.

1) Sandra bought coffee in a cup shaped like a cylinder with a radius of 10 centimeters and a height of 20 centimeters. Sandra fills the cup with coffee, but she leaves 5 centimeters of space at the top to have room for cream. What is the volume of coffee in her cup?
Given,
Radius of the cylinder 10cmHeight of the cylinder is given as 20So right now we need to find the volume of the cup i.e. like a cylinder
So she leaves 5 centimeter of gap which means the height of the cup will be
Height = 20 - 5
= 15
Applying the formula to find the volume of the cup
Volume = πr²h
= π(10)²x 15
= 1500π
Substituting π as 3.14 we get
1500 x 3.14 = 4710cm³
Hence the volume is 4710cm³

The final grade of Susan will be 81.6%
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
As per the given question, the required solution would be as:
Test grade + Lab grade + FE
Test grade = (82 × 50)/100 = 4100/100 = 41%
Lab grade = (78 × 30)/100 = 2340/100 = 23.4%
final grade = (86 × 20)/100 = 1720/100 = 17.2%
final grade = 41 + 23.4 + 17.2

Submit Question
If according to Masterfoods, the company that manufactures M&M's, 12% of peanut M&M's are brown. The probability that a randomly selected peanut M&M is not blue is 0.77.
How to find the Probability?a. The probability that a randomly selected peanut M&M is not blue:
Probability= 1 - 0.23
Probability = 0.77
b. Probability that a randomly selected peanut M&M is blue or orange
Probability = 0.23 + 0.23
Probability = 0.46
c. Probability of selecting three green M&M's in a row
Probability= (0.15)^3
Probability = 0.003375
d. Probability that neither of two randomly selected peanut M&Ms are brown
Probability = (1 - 0.12)^2
Probability = 0.7396
e. Probability that at least one of two randomly selected peanut M&Ms is brown
Using complement rule:
Probability = 1 - (1 - 0.12)^2
Probability = 0.2604
Therefore the probability that a randomly selected peanut M&M is not blue is 0.77.

When a system of equations has no solutions, it is referred to as an inconsistent system.
What is equation?An equation is a mathematical statement that two expressions are equal. It consists of two expressions, one on each side of an equal sign. Equations are used to solve problems in mathematics, chemistry, physics, engineering, and other sciences. They can also be used to define relationships between different variables or constants. Equations are an important tool for understanding the world around us.
This means that there is no solution that can satisfy all of the equations at the same time. This can happen when the equations are contradictory, or when one equation is an exact multiple of the other equation. In some cases, a system of equations may have infinitely many solutions, meaning that there are an infinite number of solutions that satisfy the equations. However, in the case of an inconsistent system, no solutions exist.

The solution of the given equation is x = -6/5.
Solving an equation:An equation is a mathematical statement that is formed by variables and constant terms. By adding or subtracting the same integer on both sides or by multiplying or dividing by the same integer on both sides we can solve an equation.
Here we have
(2 + 4x)6 = 4(x - 3)
We can solve the given expression as follows
=> (2 + 4x)6 = 4(x - 3)
=> 12 + 24x = 4x - 12
Add - 12 on both sides
=> 12 + 24x - 12 = 4x - 12 - 12
=> 24x = 4x - 24
Subtract - 4x from both sides
=> 24x - 4x = 4x - 4x - 24
=> 20x = - 24
Divided by 20 into both sides
=> 20x/20 = -24/20
=> x = - 6/5

a bowl contains 675 sweets
ratio of red to blue sweets is 3:7
ratio of blue to green sweets is 4:5
calculate the number of blue sweets
Answer:
We know that the ratio of blue to green sweets is 4:5
We can let y be the number of green sweets
the total number of sweets is 675, and we know that the ratio of blue to green sweets is 4:5, so we can set up the equation:
x + y = 675
where x is the number of blue sweets and y is the number of green sweets.
Also we know that x:y = 4:5
by cross multiplying x * 5 = y * 4
x = (5/4) y
Now we can substitute x in the first equation:
(5/4) y + y = 675
by combining like terms we get:
9/4 y = 675
multiply both sides by 4/9 to get:
y = (675 * 4) / 9
y = 300
the number of blue sweets is:
x = (5/4) y = (5/4) * 300 = 375
so the number of blue sweets is 375.

What are the six trigonometric ratios?Trigonometric ratios for a right angled triangle are from the perspective of a particular non-right angle.
In a right angled triangle, two such angles are there which are not right angled(not of 90 degrees).
The slant side is called hypotenuse.
From the considered angle, the side opposite to it is called perpendicular, and the remaining side will be called base.
From that angle (suppose its measure is θ),
[tex]\sin(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of Hypotenuse}}\\\cos(\theta) = \dfrac{\text{Length of Base }}{\text{Length of Hypotenuse}}\\\\\tan(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of base}}\\\\\cot(\theta) = \dfrac{\text{Length of base}}{\text{Length of perpendicular}}\\\\\sec(\theta) = \dfrac{\text{Length of Hypotenuse}}{\text{Length of base}}\\\\\csc(\theta) = \dfrac{\text{Length of Hypotenuse}}{\text{Length of perpendicular}}\\[/tex]

A carpenter needs to cut a small triangular piece of wood for part of a jewelry box. He knows the height is 23 inches and the base is an unknown value a. The angle between the unknown base a and the hypotenuse is θ=29∘. What is the length of a to the nearest tenth of an inch? Do not include the units in your answer.
Answer:
83
Step-by-step explanation:
Let the base be of length a
The height h, half the base a/2 and the hypotenuse form a right triangle.
Two of the angles of this triangle are known: 90° and 29°
The third angle with is opposite the side of length a/2 = 180-(90+29) = 61°
Use the Law of Sines
f a, b and c are the lengths of the legs of a triangle opposite to the angles A, B and C respectively; then the law of sines states:
[tex]\dfrac{a}{\sin A} = \dfrac{b}{\sin B} = \dfrac{c}{\sin C}[/tex]
Therefore
[tex]\dfrac{23}{\sin 29} = \dfrac{a/2}{\sin 61}\\\\\\a/2 = \dfrac{23(\sin61)}{\sin 29} = 41.493 \; inches\\[/tex]
The base length a = 2 x 41.493 = 82.986
Rounding this to the nearest tenth will make it an integer: 83
Each side of the base of a square pyramid measures 10 inches. The height of each lateral face of the pyramid is also 10 inches.
What is the surface area of the pyramid?
Enter your answer in the box.
in²
Step-by-step explanation:
The surface area of a square pyramid can be found by adding the area of the base and the sum of the areas of each of its lateral faces.
The area of the base is 10 inches * 10 inches = 100 square inches.
The lateral faces are isosceles triangles with a base of 10 inches and a height of 10 inches, so the area of each lateral face is (1/2) * 10 inches * 10 inches = 50 square inches.
Since there are 4 lateral faces, the sum of their areas is 4 * 50 = 200 square inches.
Adding the area of the base to the sum of the areas of the lateral faces:
Surface area = 100 + 200 = 300 square inches.
