What is a isosceles trapezoid?An isosceles trapezoid is a convex quadrilateral with one pair of opposite sides bisected by a line of symmetry. It is a subset of the trapezoid. It can also be defined as a trapezoid with equal lengths for both legs and base angles.
Given that the angle S= 120. The measure of the angle Q will be calculated as:-
∠Q = ∠R = 120°
The pair of the two angles with the two parallel lines are supplementary.
∠R + ∠Q = 180
120 + ∠Q = 180
∠Q = 180 - 120 = 60

An angle measuring 5.25 radians is equal to which of the measures given below? Check all that apply. - 300 degrees 48’ - 16.49 degrees - 16degree 24’ -300.8 degree
Answers
Answer:
300.8 degrees
Step-by-step explanation:
in a circle full angle is [tex]2\pi[/tex] radian
In degrees the value of angle is 360.
Thus
[tex]2\pi[/tex] radian is same as 360 degrees
thus
[tex]2\pi[/tex] radian= 360 degrees
dviding both side by [tex]2\pi[/tex]
[tex]2\pi[/tex] / [tex]2\pi[/tex] radian= 360/[tex]2\pi[/tex] degrees
1 radian= 360/[tex]2\pi[/tex] degrees
multiply both side by 5.25
1*5.25 radian= (360/[tex]2\pi[/tex]) * 5.25 degrees
using value of [tex]\pi[/tex] as 3.14 we have
5.25 radian= (360/2*3.14) * 5.25 degrees = 300.8 degrees

Answers
Answer:
The domain is all real numbers but x ≠15/14
Step-by-step explanation:
The domain is the numbers that are allowed for x
f(x) = 50 / (14x-15)
The denominator is not allowed to go to zero or we are dividing by zero
14x-15 cannot equal zero
14x-15≠0
Add 15 to each side
14x ≠15
Divide by 14
x ≠15/14
The domain is all real numbers but x ≠15/14
Real numbers are those that can be shown on a number line.
Answer:
[tex]\boxed{\frac{15}{14} }[/tex]
Step-by-step explanation:
The domain of a function is the set of all possible values for x.
If the denominator of the function equals 0, then the output is undefined.
Put up an equation to solve for x.
14x - 15 = 0
Add 15 to both the sides.
14x = 15
Divide both sides by 14.
[tex]\displaystyle \frac{14x}{14} =\frac{15}{14}[/tex]
x = [tex]\displaystyle \frac{15}{14}[/tex]

The figure below shows a cylindrical water
tank with a circular opening at the top of
radius 14cm. What is the surface area of
the tank in m??
π=22/7
Radius-25cm
Height=1.5m
Answers
Hey there! I'm happy to help!
BOTTOM CIRCLE
First, let's find the area of the bottom circle. We will use 3.14 for pi.
A=3.14×r²
A=3.14×25²
A=3.14×625
A=1962.5
TOP CIRCLE WITH OPENING
The top circle has the same area as the bottom one but the area of the opening is subtracted from it. Let's find the area of this circular opening with a radius of 14 cm.
A=3.14×14²
A=3.14×196
A=615.44
Now, we subtract this from the area of the 25 cm radius circle.
1962.5-615.44=1347.06
RECTANGLE
A cylinder is made up of a rectangle wrapped around a top and bottom circle. One side of that rectangle is the height of the cylinder and the other side is the circumference of the circle, as the top side of the rectangle wraps completely around the circle.
Let's find the circumference of the circle.
C=3.14×d
Diameter is twice the radius, so diameter is 50 cm.
C=3.14×50
C=157
We multiply this by the height.
157×1.5=235.5
TOTAL SURFACE AREA
We now combine the areas of the bottom circle, top circle with opening, and rectangle to find the surface area.
1962.5+1347.06+235.5=3545.06
Therefore, the surface area of the tank is 3545.06 m².

Over a one-month period, the first group received a low dosage of an experimental drug, the second group received a high dosage of the drug, and the third group received a placebo. The diastolic blood pressure of each participant was measured at the beginning and at the end of the period and the change in blood pressure was recorded. Identify the levels of the factor.

Here the factor is the experimental drug.
The first group received a low dosage of an experimental drug,
The second group received a high dosage of the drug,
The third group received a placebo.
It can be observed from above three statements that there are 3 levels of factor. These three levels can be used to assess the effect of the experimental drug on 780 participants suffering from high blood pressure.

Given 5 colors to choose from, how many ways can we color the four unit squares of a $2\times 2$ board, given that two colorings are considered the same if one is a rotation of the other? (Note that we can use the same color for more than one square.)
Answers
Answer:
165
Step-by-step explanation:
we solve this by sum over the possible symmetry groups of the colorings.
1.If the board has 90 degree rotational symmetry, then all four squares are the same color. There are 5 such boards.
2. If the board has 180 degree rotational symmetry (but not 90 degree), then it has to be a 2-color checkerboard pattern. There are ⁵c₂=10 such boards.
All the remaining boards have no rotational symmetry. We can count these boards by taking all possible colorings, subtracting the ones counted above, and dividing by four (since each of these boards corresponds to four colorings). The result is (54−2×10−5)÷4=600÷4=150.
so, total number of boards= 5+10+150= 165.

Ginnie plans to paint a wall. She measures its height and width. She finds that she needs enough paint to cover 8 square meters. Which measurement does 8 square meters represent?
Answers
Answer:
The 8 square meters represent the product of the height by the width of the wall and therefore, its area.
Step-by-step explanation:
Ginnie is going to paint a wall and measures the height and the width, the walls are usually in the form of a rectangle or square. To find the area of both we need to multiply the height by the width (in the case of the square both are the same) and this will give us the total amount of paint that we need to paint the wall.
In this example, Ginnie finds that she needs enough paint to cover 8 square meters, therefore, these 8 square meters represent the product of the height by the width (that we don't know but it doesn't matter) of the wall and therefore, its area.
34=3(y+6)-8 Please Explain.
Answers
Answer:
y =8
Step-by-step explanation:
34=3(y+6)-8
Add 8 to each side
34+8=3(y+6)-8+8
42 =3(y+6)
Divide by 3
42/3 = 3(y+6)/3
14 = y+6
Subtract 6 from each side
14-6 = y+6-6
8 = y
Answer:
y = 8
Step-by-step explanation:
Add 8 to both sides.
42=3(y+6)
Divide 3 from both sides.
14=y+6
Subtract 6 from both sides.
8 = y
If the polynomial - 6 + 16 - 25x + 10 is divided by - 2x + k, the remainder comes out to be x + a, find k and a
Answers
Answer:
k=5
a= -5
Step-by-step explanation:
if the polynomial x^4-6x^3+16x^2-25x+10 is divided by x^2-2x+k the remainder comes out to be x+a,find k and a
Solution
x^4-6x^3+16x^2-25x+10 / x^2-2x+k = x-a
We have,
(4k-25+16-2k)x+[10-k(8-k)] = x+a
(2k+9)x + (10-8k+k^2)=x+a
2k-9=1
2k=1+9
2k=10
Divide both sides by 2
2k/2=10/2
k=5
And
10-8k+k^2=a
10-8(5)+(5^2)=a
10-40+25=a
-5=a
Therefore, a=-5
x^4-6x^3+16x^2-25x+10 divided by x^2-2x+5 = x-5

There are the same angles in similar triangles but sides not necessarily.
In congruent triangles there are the same angles and the same sides.
Reflection, rotation or translation changes only position of triangle or mirrors it. Doesn't change the size, so the created triangle is congruent.

The translation of the x-coordinate is written as x⇒0 for the triangle ABC.
What is translation?A translation in mathematics moves a shape left, right, up, or down but does not turn it. The translated (or image) shapes appear to be the same size as the original shape, indicating that they are congruent. They've just moved in one or more directions.
A coordinate system is a two-dimensional number line, such as two perpendicular axes. This is an example of a typical coordinate system: The horizontal axis is referred to as the x-axis, and the vertical axis is referred to as the y-axis.
Given that on a coordinate plane, triangle A B C has shifted 6 units up. The x translation for the triangle is zero.
The x-coordinate translation is written as,
