Answer:
54degrees
Step-by-step explanation:
Find the diagram attached
Since the angle of the triangle in a semicircle is a right angle, hence <DCB = 90 degrees
Given
<DBC= 36 degrees
Required
<DBC
Since the sum of angles in the triangle DBC is 180 degrees, hence;
<DBC+<DBC+<DCB = 180
<DBC+36+90 = 180
<DBC + 126 = 180
<DBC = 180 - 126
<DBC = 54degrees
Hence the measure of angle DBC is 54degrees

Answer:
[tex]no \: solution[/tex]
Step-by-step explanation:
1) Expand
[tex]6x - 36 - 5x + 35 = x + 6[/tex]
2) Simplify 6x - 36 - 5x + 35 to x - 1.
[tex]x - 1 = x + 6[/tex]
3) Cancle x on both sides.
[tex] - 1 = 6[/tex]
4) Since −1 = 6 is false, there is no solution.
No Solution

Triangle LMN similar to triangle OPQ find the measure of side PQ round your answer to the nearest 10th if necessary
*see attachement for the triangles given
Answer:
PQ = 6.8
Step-by-step explanation:
Corresponding sides of similar shapes or figures are proportional to each other. Since ∆LMN ~ ∆OPQ, the ratio of their corresponding sides would therefore be equal. Thus:
LN/OQ = MN/PQ
LN = 5
OQ = 17
MN = 2
PQ = ?
Plug in the values
5/17 = 2/PQ
Cross multiply
5*PQ = 2*17
5*PQ = 34
PQ = 34/5
PQ = 6.8

Answer:
551.8 feet
Step-by-step explanation:
We are given
Adjacent = 1300 feet
Opposite = x
Angle = 23°
We solve using the trigonometric function Tangent
tan θ = Opposite/Adjacent
tan 23 = x/1300 feet
Cross Multiply
x = tan 23 × 1300 feet
x = 551.81726107 feet
Approximately = 551.8 feet
The Length of the building = 551.8 feet

what is 2x + 20 + 2x = 60
Answer:
= 1 0
Step-by-step explanation:
Solve
1. Combine like terms
2 + 2 0 + 2 = 6 0
4 + 2 0 = 6 0
2. Subtract 20 from both sides of the equation
4 + 2 0 = 6 0
4 + 2 0 − 2 0 = 6 0 − 2 0
3. Simplify
Subtract the numbers4 + 2 0 − 2 0 = 6 0 − 2 0
4 = 6 0 − 2 0
Subtract the numbers4 = 6 0 − 2 0
4 = 4 0
4. Divide both sides of the equation by the same term
4x = 40
4x/4 = 40/4
5. Simplify
Cancel terms that are in both the numerator and denominator4x/4 = 40/4
x = 40/4
Divide the numbersx = 40/4
x = 10
2) What x value makes the exponential function greater than the
quadratic function?
A)X = -2
B)x = 0
X = 2
D) =4
Answer:
The answer is b
Step-by-step explanation:
X= 0 makes the exponential function greater than the quadratic function. Therefore, the correct option is option B.
What is exponential function?The mathematical symbol for the exponent is [tex]e^{X}[/tex]. The word, unless specifically stated differently, generally relates to the positive-valued functional of something like a real variable, though it can be extended towards the complex numbers or adapted to other mathematical like matrices or Lie algebras.
The idea of exponentiation is where the exponential function got its start, although recent definitions allow for a rigorous extension to all real arguments, especially irrational values. X= 0 makes the exponential function greater than the quadratic function.
Therefore, the correct option is option B.

Answer:
The mean of the data points is 2.
Step-by-step explanation:
The mean of data is all data point values added together and divided by the number of data points, or the average of all data points. All the numbers above added together is 42, and there are 21 data points, which means the mean of the data is [tex]\frac{42}{21}[/tex] or 2.
Answer:
2

Add all the numbers up then divide by how many number there are to find the mean
4 + 2 + 4 +1+ 1+2+2+3+ 0+ 2+ 1+1+4 +2+5+2+1+1+0+ 2+2 =42
42 divided by 21= 2
There are 24 cans of soda arranged in 4 rows of 6 cans each. Each can is a
cylinder with a radius of 4 cm and a height of 15 cm. These cans are to be packed
snuggly into a rectangular prism case with no extra space on the top, bottom, or
sides. Determine the volume, in cubic centimeters, of the case (rectangular prism).
Answer:
23,040 cm^3.
Step-by-step explanation:
The case will be 6 * diameter of a can in length,
= 6* 8= 48 cm.
The width will be 4 * 8 = 32 cm.
The height = height of each can
= 15 cm.
So the volume of the case = 15*32*48
= 23,040 cm^3.

What is a polygon?A polygon is a closed figure made up of three or more line segments connected end to end.
A polygon in the plane has rotational symmetry when the figure is mapped onto itself by rotating between 0 and 360° about its center.
So, we need to find the number of symmetrical lines a regular polygon.
A regular polygon with a sides has n lines of symmetry and order of symmetry.
Then, let a be the number of symmetrical line lines

Cash Orcheck had a balance of $867 in his checking account on
January 1. During January, Cash wrote checks for the following
amounts: $98. $456, $29, and $381. What was his balance at the
end of January?
Answer:
Well since he wrote the amount, he’s technically giving cash away so you basically jsut add everything.
98+456+29+381= 964
867-964= -97
His final balance would be -97
Here’s the thing, a checking account acts like a debit card. Its your own cold hard cash. That means you can’t give away more then you have.
So here are the two options
