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 prism?A prism is a solid shape that is bound on all its sides by plane faces. There are two types of faces in a prism. The top and bottom faces are identical and are called bases. A prism is named after the shape of these bases. For example, if a prism has a triangular base it is called a triangular prism.The faces other than the top and bottom of a prism are called its lateral faces. All the lateral faces are also identical to each other and belong to the class of parallelograms. This means that the lateral faces can either be parallelograms, rectangles, or even squares since all of them have their opposite sides parallel to each other.

Build a function from the following data:
The function represented by the table can be written as:
y = -4x + 3
How to find the function?Here we have a function represented by a table. Notice that for each increase of one unit in the x-value, the y-value decreases by 4.
Then we have a linear function, which can be written in a general form as:
y = a*x +b
Where a isthe slope and b is the y-intercept.
Because of the first pair on the table, (0, 3), we conclude that the y-intercept is 3, then we can rewrite:
y = a*x + 3
Now we can use the second point (1, - 1) and replace the values on the equation above.
-1 = a*1 + 3
-1 = a + 3
-1 - 3 = a
-4 = a

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.
Consider an example 25/5=5-----quotient.

Sarah made baket on ome of her hot in a baketball game. If he continue to make baket at the ame rate, how many baket will Sarah make in her next 6 hot
Sarah will make 6 baskets in her next 6 shots.
If Sarah made a basket on one of her first shots in a basketball game, and she continues to make baskets at the same rate, we can use that information to predict the number of baskets she will make in her next 6 shots.
Since we know that Sarah made a basket on one of her first shots, we can assume that the probability of her making a basket on any given shot is 1/1 or 100%.
If the probability of Sarah making a basket on any given shot is 100%, then we can expect her to make a basket on all 6 of her next shots. Therefore, Sarah will make 6 baskets in her next 6 shots.
Therefore, Sarah will make 6 baskets in her next 6 shots.

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.

How do you find the factor of a remainder theorem?
The Remainder Theorem states that if a polynomial P(x) is divided by (x - c), the remainder is P(c). To find the factor of a polynomial using the Remainder Theorem, you can use the following steps:
Start by assuming that the polynomial can be factored into (x - c) and some other polynomial Q(x).Divide P(x) by (x - c) using polynomial long division, and find the remainder R(x).Use the Remainder Theorem to set P(c) = R(c) = 0.Solve for c to find the value that makes P(c) = 0.Use the value of c found in step 4 to factor (x - c) out of P(x).Repeat the process with the remaining polynomial Q(x) until the polynomial is completely factored in.Example:
P(x) = x^3 + 3x^2 + 2x -6
Factor = (x-2)
P(2) = 8 + 12 + 4 - 6 = 0
