A paper company needs to ship paper to a large printing business. The paper will be shipped in small boxes and large boxes. The volume of each small box is 7 cubic feet and the volume of each large box is 20 cubic feet. There were 8 more small boxes shipped than large boxes and the total volume of all boxes was 245 cubic feet. Determine the number of small boxes shipped and the number of large boxes shipped.
Using equations, the number of small boxes shipped is 15 while the number of large boxes shipped is 7.
What is an equation?An equation is described as a mathematical statement of the equality of two or more mathematical expressions.
Equations use the equation sign (=) to show that the expressions are equivalent or equal.
The volume of each small box = 7 ft³
The volume of each large box = 20 ft³
The number of small boxes = x + 8
The number of large boxes = x
The total volume of all the boxes = 245 ft³
The total volume of the 8 additional small boxes = 56 ft³ (8 x 7 ft³)
The remaining volume of the boxes after subtracting the volume of the 8 additional small boxes = 189 ft³ (245 - 56)
Equations:7x + 56 + 20x = 245
7x + 20x = 189
27x = 189
x = 7 (189/27)
The number of small boxes shipped, x + 8 = 7 + 8 = 15 boxes
The number of large boxes shipped, x = 7 boxes
Check:
Small boxes = 15 x 7 ft³ = 105 ft³
Large boxes = 7 x 20 ft³ = 140 ft³
Total 22 245 ft³
Thus, the paper company shipped 15 small boxes with 7 large boxes.

A and b are mutually exclusive events. If p(a)=0. 07692 and p(b)=0. 25, what is the probability probability of a or b. To four decimal places? select one.
The probability of A or B would be 0.3269. Probability can be used to make predictions and make decisions based on uncertain information in fields such as finance, engineering, and science.
Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, with 0 indicating that an event will not occur and 1 indicating that an event will definitely occur. Events with probabilities closer to 1 are considered more likely to happen, while events with probabilities closer to 0 are considered less likely.
Since A and B are mutually exclusive events, they cannot occur at the same time. Therefore, the probability of A or B is the sum of their individual probabilities.
p(A or B) = p(A) + p(B) = 0.07692 + 0.25 = 0.32692

The m ∠SPR of the rhombus with sides PQRS is 65, option C.
How to find the angle of a rhombus?Only the opposite angles of a rhombus are equal. A rhombus's diagonal angle is 90 degrees.
There are two ways to find the angle SPR of the rhombus, PQRS;
If ∠PQR = 50° then, ∠PQR = ∠PSR (opposite sides)
∠OSR = 1/2 x 50° = 25° where SQ bisects ∠PSR
∠ORS + ∠ROS + ∠OSR = 180°
∠ORS + 25° + 90° = 180°
∠ORS = 180° - 115°
∠ORS = 65°
Also, it can be calculated thus:
Because rhombus adjacent sides are supplementary, it can be written as; ∠QRS + ∠PQR = 180°
∠QRS = 180° - ∠PQR
∠QRS = 180° - 50°
∠QRS = 130°
Even though a rhombus' diagonal is an angular bisector, the ∠PRS is half of the ∠QRS.
Therefore ∠SPR = ∠QRS/2
∠SPR = 130°/2
∠SPR = 65°
The value of ∠SPR is half the angle because the opposite angles are equal therefore each side has 65°.

What is a rational expression?A rational expression is simply a fraction with polynomials as the numerator and denominator. When the denominator of a rational expression equals 0 (because division by 0 is undefined), you get excluded values.
The numerator can be any number. It could be 1, 10000x + x² or anything that comes to mind. Any polynomial in the numerator will not produce an excluded value. We get ( x - ( - 2 ) ) and ( x - 2 ) by excluding -2 and 2. We multiply them together: ( x + 2 ) ( x - 2 ) = x² - 4.

The volume of air in the spherical ball is [tex]\frac{4}{3}\cdot \pi\cdot 3^3\cdot 10^6[/tex]. So the option A is correct.
In the given question, we have to find the volume of air in the spherical ball.
A sphere's capacity is measured by its volume. It is the area the sphere calls home. Cubic units are used to express the volume of a sphere. The sphere has a three-dimensional, rounded shape. Its shape is defined by its three axes, which are the x, y, and z axes.
Since the cross-section of the sphere is a circle, the volume in this situation is dependent on the radius's diameter. A sphere's surface area is the area or region of its outside. The following formula can be used to determine the volume of a sphere whose radius is "r":
V = [tex]\frac{4}{3}\pi r^{3}[/tex]
As given r = 3·10^2. So,
V = [tex]\frac{4}{3}\pi (3\cdot 10^2)^{3}[/tex]
V = [tex]\frac{4}{3}\cdot \pi\cdot 3^3\cdot 10^6[/tex]

What's the quotient in division?
The quotient is the number that is generated when we perform division operations on two numbers, and the result of the division is called the quotient.
There are four main terminologies used in the arithmetic division such as divisor, dividend, quotient, and remainder.
The number is divided by another number to get a different number as an output.
Dividend = Quotient × Divisor + Remainder
If the remainder is equal to 0, then;
Dividend = Quotient × Divisor
Therefore,
Quotient = Dividend ÷ Divisor
Dividend: The number which is required to be divided
Divisor: The number which divides the given dividend
Remainder: The number which is left after the division method. When a number is completely divided then the remainder is zero.
