Answers
Answer:
Step-by-step explanation:
Given
<LON = 77°
<LOM = (9x+44)°
<MON = (6x+3)°
The addition postulate is true for the given angles since tey have a common point O:
<LON = <LOM+<MON
Since we are not told what to find we can as well look for the value of x, <LOM and <MON
Substitute the given parameters and get x
77 = 9x+44+6x+3
77 = 15x+47
77-47 = 15x
30 = 15x
x = 30/15
x = 2
Get <LOM:
<LOM = 9x+44
<LOM = 9(2)+44
<LOM = 18+44
<LOM = 62°
Get <MON:
<MON = 6x+3
<MON = 6(2)+3
<MON = 12+3
<MON = 15°

Daniel works in a market. He has a large bag of potatoes that weighs 261/4 pounds and he is going to sell them in smaller bags of 9/4 pounds each. If he uses up all the potatoes, how many smaller bags of potatoes will Daniel have filled?
Answers
Answer:
11 6/9
Step-by-step explanation:
Daniel works in a market
He has large bags of potatoes that weighs 26 1/4
Daniel is going to sell them in smaller bags 9/4 pounds each
Therefore the number of smaller bags of potatoes in which Daniel would have filled can be calculated as follows
= 26 1/4 ÷ 9/4
= 105/4 ÷ 9/4
= 105/4 × 4/9
= 105/9
= 11 6/9

DMC Inc. Is planning to issue a $1,000 face value bond with an annual coupon rate of 10% that matures in 20 years. DMC is planning to pay semiannual interest payments. Similar DMC bonds are quoting at 95% of par. What is yield to maturity for this bond?
Answers
Answer: 10.6%
Step-by-step explanation:
Given the following :
Face value (FV) = $1000
Coupon rate (C) = 10% paid semianually
Time to maturity = 20 years ; number of periods =( 20 * 2) = 40 (Semi-annual)
Current trading price of bond = 95% * 1000 = $950
Payment per period = (10%) / 2 * 1000 = 0.05 * 1000 = 50
Inputting the parameters above into the the yield to maturity calculator with semiannual payment,
Yield to maturity (YTM) = 10.6%

P=log(2)+log(3)+4.log(x)
Step-by-step explanation:
To solve the problem, we need to recall the following properties of the logarithms:
[tex]log(x.y)=log(x)+log(y)[/tex]
[tex]log(x^y)=y.log(x)[/tex]
We have the expression:
[tex]P=log(6x^4)[/tex]
Factor 6=2*3:
[tex]P=log(2\cdot 3x^4)[/tex]
Apply the property of the product:
[tex]P=log(2)+log(3)+log(x^4)[/tex]
Now apply the property of the exponent:
P=log(2)+log(3)+4.log(x)

Alex can run 5/4 miles in 1/12 hour. At this rate, how far can he run in 1 hour?
Answers
Answer:
15 miles in one hour
Step-by-step explanation:
Since we know that we need twelve 1/12 hours to make one full hour, we can multiply.
5/4 * 12
5/4 * 12/1
60/4
15
Best of Luck!
Answer: 15 miles
If he can already run 5/4 miles in 1/12 of an hour, we multiply.
First, let's simplify 5/4 to make it easier.
5/4 = 1 1/4.
Alex ran 1 1/4 miles in 1/12 of a hour.
Now, let's multiply 1 1/4 by 12.
1 1/4 x 12 = 15.
Answer = 15 miles. Hope this helps!
Franco begins to save for a new Lego set that costs $65. His parents gave him $35 towards the cost
and he plans to save $5 per week. Define all unknown variables. Write an equation modeling the total
amount he has saved.
Answers
Answer:
65-35=30
30 divided by 5 = 6
Step-by-step explanation:
First you have to subtract 65-35, which equals 30.
Then the problem says he plans to save 5 each week. That means he should get his lego set in 6 weeks, because 30 divided by 5 = 6
65-35=30
30 divided by 5 = 6
