Step 1: Define

0.8k - 20 = -60
Step 2: Solve for k
[Addition Property of Equality] Add 20 on both sides: 0.8k = -40[Division Property of Equality] Divide 0.8 on both sides: k = -50Answer:
k = - 50
Step-by-step explanation:
0.8 k - 20 = - 60
Add 20 to each side
0.8 k - 20 + 20 = - 60 + 20
0.8 k = - 40
divide each side by 0.8
0.8 k / 0.8 = -40 / 0.8
k = - 50
7+2ax =13 solve the equations for x and match the solution
Answers
Answer:
x = 3/a a cannot equal zero
Step-by-step explanation:
7+2ax =13
Subtract 7 from each side
7-7+2ax =13-7
2ax = 6
Divide each side by 2a
2ax/2a = 6/2a
x = 3/a a cannot equal zero
) Would you rather receive $1,500 a year for 12 years, or $1,200 a year for 20 years if the interest rate is 7%?
Answers
Answer:
$1200 should receive.
Step-by-step explanation:
To check whether to receive $1500 or $1200 just find the present values of each amount.
Present value of annuity $1500:
Present value of annuity = Annuity (P/A, 7%, 12)
Present value of annuity = 1500 (P/A, 7%, 12)
Present value of annuity = 1500 (7.9426)
Present value of annuity = $11913.9
Present value of annuity $1200:
Present value of annuity = Annuity (P/A, 7%, 20)
Present value of annuity = 1500 (P/A, 7%, 20)
Present value of annuity = 1500 (10.5940)
Present value of annuity = $15891
Thus, $1200 should receive.
The half-life of a radioactive kind of protactinium is one minute. If you start with 88 g of it, how much will be left over after two minutes?
Answers
Answer:
22 grams
Step-by-step explanation:
Divide the number of minutes by the half life... 2/1=2
Multiply starting amount by one-half (1/2) a total of the number of half-lives that have passed. ( 2 half lives in our case)
88 * 1/2 *1/2 = 22 grams also written as 88(1/2)^2
sorry if i am asking a lot, totally suprised by this and dont know what to do and yall are great, i need to find X and Y with exact values and no decimals
Answers
Answer:
x and y = 19
Step-by-step explanation:
sin 45/x = sin90/19[tex]\sqrt{2}[/tex]
19[tex]\sqrt{2}[/tex]×sin45=sin90x
x=19
Pythagorean theorem for y
[tex]y^{2}[/tex]=(19[tex]\sqrt{2}[/tex])^2 - 19^2
y^2= 722 - 361
y^2= 361
y=19

Step-by-step explanation:
Daniel goes out to lunch. The bill, before tax and tip, was $14.20. A sales tax of 8% was added on. Daniel tipped 24% on the amount after the sales tax was added. What was the total cost of the meal, plus tax and tip? Round to the nearest cent.
Answers
Answer: $19.02
Step-by-step explanation:
First find the sales tax paid. It will be paid on the cost of the meal:
= 14.20 * 8%
= $1.14
Then find the tip which was done after the sales tax was added:
= 24% * (14.20 + 1.14)
= 24% * 15.34
= $3.68
The total cost is:
= Gross amount + Sales tax + tip
= 14.20 + 1.14 + 3.68
= $19.02

Find the value of x (Angles)
Answers
Answer:
x = 83
Step-by-step explanation:
The two angles form a right angle, which is 90 degrees
25+ x-18 = 90
Combine like terms
x +7 =90
Subtract x from each side
x+7-7=90-7
x = 83
Answer:
Hello! answer: x = 83
Step-by-step explanation:
This is a Complementary angle meaning it will add up to 90 degrees so...
83 - 18 = 65 65 + 25 = 90 therefore x = 83 Hope that helps!
