Based on the diagram below, what is the measure of arc DC?
28 degrees
68 degrees
108 degrees
112 degrees
Answer:
108 °
Step-by-step explanation:
∠DOC = 180° - 112° = 68°
∠DOC = 1/2(arc AB + arc DC)
68 = 1/2(y + 80 + y)
68 = y + 40
y = 28
arc dc = 80 + 28 = 108 °

Given:
In a parallelogram [tex]PRTV, VQ\perp PR,VS\perp RT[/tex].
To prove:
[tex]\dfrac{PQ}{ST}=\dfrac{PV}{VT}[/tex]
Solution:
It is given that [tex]VQ\perp PR,VS\perp RT[/tex], it means [tex]\angle PQV[/tex] and [tex]\angle TSV[/tex] are right angle triangles.
In triangle PQV and triangle TSV,
[tex]\angle PQV\cong \angle TSV[/tex] (Right angles)
[tex]\angle QPV\cong \angle STV[/tex] (Opposite angles of a parallelogram)
Two corresponding angles are congruent. So, by AA property of similarity, we get
[tex]\Delta PQV\sim \Delta TSV[/tex]
We know that the corresponding parts of similar triangles are proportional. So,
[tex]\dfrac{PQ}{TS}=\dfrac{PV}{TV}[/tex]
It can be rewritten as:
[tex]\dfrac{PQ}{ST}=\dfrac{PV}{VT}[/tex]
Hence proved.
Carl has a new job making $8.25 an hour. He worked 16.75 hours last week. He also
had deductions of 6.25% for Social Security and 1.45% for unemployment insurance.
What was Carl's net pay last week (the amount after deductions)?
Answer:
Step-by-step explanation:
Earnings = 16.75 hours × $8.25/hour = $138.1875
Deductions = 6.5% + 1.45% = 7.95%
net = 92.05% of $138.1875 ≈ $127.20
Cool Tees buys a shirt for $21. The sale price is120% of the original price. What is the sale price for this shirt?
Answer:
$25.20
Step-by-step explanation:
All you have to do is 21x1.20 and you get 25.2. Brainliest would be very helpful and appreciated.
Answer:
$25.20
Step-by-step explanation:
You do 21 times the decimal form of the fraction 120.
The way you make it decimal form is by moving the decimal places two spaces to the left.
So 1.20
So 21 • 1.20
25.20
So 25.20 is 120% of it
Image point B'(4, -8) was transformed using the translation ( x - 2, y + 3). What were the coordinates of B?
(6, -11)
(2, -5)
(2, -11)
(6, -5)
Answer:
(6, -11)
Step-by-step explanation:
In this problem, you are given the image and you need to find the pre-image. To do this work backward and do the opposite of the translation. So, to find the pre-image solve [tex](x+2, y-3)[/tex]. Once you plug in the points you get [tex](6,-11)[/tex] which must be the original point.
Answer:
(6, -11)

Evaluate the expression 2x -x2for x =5
Answer:
7
Step-by-step explanation:
First, you need to plug in the values for x. Here, we know that x = 5. So, when we plug it in we get 2^5 - 5^2. When we simplify, we then get 32 - 25. Thus, 32 - 25 = 7.

I dont get this Rewrite the equation below so that it does not have fractions. 2-(3)/(4)x=(9)/(10) Do not use decimals in your answer.
Answer:
Suppose we have an equation like:
[tex]\frac{A}{C} = \frac{B}{D}[/tex]
If we want to remove the denominators, we should multiply both sides by each denominator.
First, let's multiply both sides by C.
[tex]\frac{A}{C}*C = \frac{B}{D}*C[/tex]
[tex]A = \frac{B}{D}*C[/tex]
Now let's multiply both sides by D.
[tex]A*D = \frac{B}{D}*C*D[/tex]
[tex]A*D = B*C[/tex]
So now we removed the denominators.
Now let's do this to our expression.
[tex]2 - \frac{3}{4*x} = \frac{9}{10}[/tex]
First, let's multiply both sides by 10
[tex](2 - \frac{3}{4*x})*10 = \frac{9}{10}*10[/tex]
[tex]20 + \frac{30}{4*x} = 9[/tex]
Now let's multiply both sides by 4*x
[tex](20 + \frac{30}{4*x})*4*x = 9*4*x[/tex]
[tex]20*4*x - 30 = 9*4*x[/tex]
[tex]80*x - 30 = 36*x[/tex]
Now we can solve this for x:
[tex]80*x - 36*x = 30[/tex]
[tex]44*x = 30[/tex]
[tex]x = \frac{30}{44} = 0.68[/tex]

Answer:
x = 16 and y = 116
Step-by-step explanation
For the trapezoid, the sum of the adjacent side is 180. Hence;
6x+20 + 4x = 180
10x + 20 = 180
10x = 180-20
10x = 160
x = 160/10
x = 16
Also, the sum of opposite side is 180, hence;
4(16)+ y = 180
64 + y = 180
y = 180 - 64
y = 116 degrees
hence x = 16 and y = 116

A European bond has a par value of 1000 Euros, a coupon rate of 4.5 percent and a yield to maturity of 3.2 percent. The bond has 19 years to maturity. Coupons are made annually. What is the value of the bond?
Answer:
Bond Price= 1,182.96
Step-by-step explanation:
Giving the following information:
Par value= 1,000
Cuopon= 1,000*0.045= 45
YTM= 3.2%
Number of years (n)= 10
To calculate the price of the bond, we need to use the following formula:
Bond Price= cupon*{[1 - (1+i)^-n] / i} + [face value/(1+i)^n]
Bond Price= 45*{[1 - (1.032^-19)] / 0.032} + [1,000 / (1.032^19)]
Bond Price= 633.31 + 549.65
Bond Price= 1,182.96

Remark
Surface area for this = Top + bottom + left side + 2 triangles.
The hypotenuse of the triangle can be found by the Pythagorean Theorem.
a^2 + b^2 = c^2
a = 6
b = 8
c = ?
c^2 = 6^2 + 8^2
c^2 = 36 + 64
c^2 = 100
sqrt(c^2) = sqrt(100)
c = 10
Top
Top = Length * Width
Top = 12 * hypotenuse
Top = 12 * 10
Top = 120
Left side = L*W
L = 12
W = 6
Area = 6 * 12
Area = 72
Two triangles
Two Triangles = 2* (1/2) * 6 * 8 = 48

W = 8
L = 12

how do i find the diameter of a circle with only knowing the area?
Answer:
2 * (Area/pi)^(1/2) = diameter
Step-by-step explanation:
The equation for the area of a circle is A = pi * r^2
We can divide both sides by pi to get:
A/pi = r^2
Then take the square root of both sides to get:
(A/pi)^(1/2) = r
Then, since D = 2 * r, we can multiply both sides of the above equation by 2 to get:
2 * (A/pi)^(1/2) = 2 * r = D
