Triangle XYZ is an isosceles triangle, then ∠Z and ∠X (also called u) measure the same.
The addition of the internal angles of a triangle is equal to 180°:
∠X + ∠Y + ∠Z = 180°
Replacing with ∠X = ∠Z = u, and ∠Y = 112°:
u + 112° + u = 180°
2u + 112° = 180°
2u = 180° - 112°
2u = 68°
u = 68°/2
u = 34°
Parker has tangerines and apricots in a ratio of 12:95. How many apricots does hehave if he has 96 tangerines?On the double number line below, fill in the given values, then use multiplication ordivision to find the missing value.
We know that if Parker has 12 tangerines he has 95 apricots, so to find how many apricots he has we need to do a rule of tree
[tex]\begin{gathered} x\text{ apricots }\cdot\frac{12\text{ tangerines}}{95\text{ apricots}}=96\text{ tangerines} \\ x\text{ apricots = 96 tangerines }\cdot\frac{95\text{ apricots}}{12\text{ tangerines}} \\ x\text{ apricots =}\frac{96\cdot95}{12}\text{ apricots = }\frac{9120}{12}\text{ apricots} \\ x=760 \end{gathered}[/tex]So the answer is that Parker has 760 apricots is he has 96 tangerines.

The length of an arc of a circle is 5/3 pi feet. Find the measure of the angle that subtends (forms)the arc if the diameter is 18 feet.
EXPLANATION
We are given the following parameters:
Length of arc= 5/3pi
Diameter = 18 feet
Therefore, radius =18/2 = 9 feets
The formula for the length of the arc is given below.

Find its width, in feet.
Answer: The width is 37 feet
Given data
Volume = 10, 878 cubic feet
Length = 7 feet
Height = 42 feet
width = ?
Let width = w
Volume of the rectangular prism = l x w x h
10, 878 = 7 x 42 x w
10, 878 = 294 x w
10, 878 = 294w
Divide both sides by 294
10, 878 /294 = 294w/294
w = 10, 878 / 294
w = 37 feet
Therefore, the width is 37 feet
A pound of pistachios cost 6.60. and you buy 2.75 pounds
By performing some simple mathematical operations, we know that the total cost of 2.75 pounds of pistachios is $18.15.
What are mathematical operations?An operation is a function in mathematics that transforms zero or more input values into a clearly defined output value. The operation's arity is determined by the number of operands. The rules that specify the order in which we should solve an expression involving many operations are known as the order of operations. PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition Subtraction (from left to right).
So, the total cost will be:
1 pound of pistachios costs $6.60.We purchased 2.75 pounds.Then, the total cost will be:

ABC and BCD are identical triangles. The overlapping area is 19cm . Find the area ofthe shaded figure.
The area of the shaded figure is 45 [tex]cm^{2}[/tex]
It is given that ABC and BCD are identical triangles and the overlapping area is 19[tex]cm^{2}[/tex]
Now, to evaluate the area of the shaded figure, we will calculate the area of the two triangles ABC and BCD, then we will subtract the overlapping area from it.
So, by evaluating the figure, it comes out that the length of the triangle is 4 units and 1 unit is 2cm.
So, Height of the triangle = 4 * 2 cm = 8 cm
And the base of the triangle is 3 units, then,
Base of the triangle = 3* 2 cm = 6 cm
The area of the triangle = 1/2 * base* height
Area of triangle ABC = [tex]\frac{1}{2} *8*6 = 24cm^{2}[/tex]
The area of both the triangles = area(ABC) +area(BCD)
Since two the triangles are identical, their areas are also identical,
So, the Area of both the triangles = 2*area(ABC) = 2*24 = 64[tex]cm^{2}[/tex]
Now, The area of the shaded figure = area(ABC) +area(BCD) - overlapping area.
The area of the shaded figure = 64 - 19 = 45 [tex]cm^{2}[/tex]

Answer
70
Explanations;
Given the following datasets that represents the scores of Janet in her math tests
65, 78, 56, 73, 67, 92.
The median is the middle value of the dataset after rearrangement. On rearranging in ascending order;
56, 65 (67, 73) 78, 92
Since there are 2 numbers at the middle, hence the median is the mean value of the data
[tex]\begin{gathered} Median=\frac{67+73}{2} \\ Median=\frac{140}{2} \\ Median=70 \end{gathered}[/tex]Hence the median scores is 70

A polynomial written in factorized form is giving us the information we need about the roots or zeros.
In this case, the polynomial is:
[tex]f(x)=(x-1)(x-1)(x+7)=(x-1)^2(x+7)[/tex]In this case, we have two zeros: x=1 and x=-7.
NOTE: a zero "a" will be expressed in a factor (x-a). That is why the zeros are 1 and -7.
As x=1 appears 2 times as a factor, we can group the factor.
x=1 is a zero with multiplicity of 2.
