What is the perimeter of the triangle? (Round to the nearest tenth)
Answers
Answer:
P = 43.3
Step-by-step explanation:
sin 38° = EF/18
EF = 18·sin 38°
EF = 11.1
to find DF:
sin 90°/18 = sin 52°/DF
1/18 = .79/DF
DF = 14.2

Cool Tees buys a shirt for $21. The sale price is120% of the original price. What is the sale price for this shirt?
Answers
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

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.

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)?
Answers
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

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
Base
W = 8
L = 12
Area = L*W
Area = 8 * 12 96
Total area = 96 + 48 + 72+120 = 336

The salary of college professors from more than 25,000 universities and colleges in USA is normally distributed with a mean, $85,900 and its standard deviation, $11,000. If you collect a random sample from 35 professors, find the probability that the sample mean is between $70,000 and $100,000?
Answers
Answer:
The answer is below
Step-by-step explanation:
The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by the formula:
[tex]z=\frac{x-\mu}{\sigma} \\\\where\ x=raw\ score,\mean,\ \sigma=standard\ deviation.\\\\For \ a\ sample\ size(n):\\\\z=\frac{x-\mu}{\sigma/\sqrt{n} }[/tex]
Therefore given that μ = $85900, σ = $11000, n = 35.
For x > 70000:
[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{70000-85900}{11000/\sqrt{35} } =-8.55\\[/tex]
For x < 100000
[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{100000-85900}{11000/\sqrt{35} } =7.58[/tex]
From the normal distribution table, P(70000< x < 100000) = P(-8.55 < z < 7.58) = P(z < 7.58) - P(z < -8.55) = 1 - 0 = 1 = 100%

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.
Answers
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]
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?
Answers
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

108 degrees
112 degrees
Answers
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 °
