What is 2/3 as a decimal
Answer:
[tex]. \frac{}{66} [/tex]
Answer:
0.66666667
Step-by-step explanation:
−9x+5<17 and 13x+25<−1 solve for x
-9x + 5 < 17
Subtract 5 from both sides:
-9x < 12
Divide both sides by -9, and because you are dividing by a negative value the inequality sign gets reversed:
X > -12/9
Simplify:
X > -4/3
13x + 25 < -1
Subtract 25 from both sides:
13x < -26
Divide both sides by 13:
X < -26/13
X < -2

You have researched your dream around-the-world vacation and determined that the total cost of the vacation will be $39,000. You feel you can earn an APR of 10.5 percent compounded monthly and plan to save $485 per month until you reach your goal. How many years will it be until you reach your goal and enjoy your well-deserved vacation?
Answer:
41.8 years
Step-by-step explanation:
From
[tex]A = P(1+r/n)^{nt}[/tex]
A= 39000
r = 10.5%
P = $ 485
n=12
t = the unknown
t= [ ln(A) - ln(P) ] / n[ln(1 + r/n)]
t= ln 39000 - ln 485/ 12[ln(1+0.105/12)]
t= 10.57 - 6.18/0.105
t= 41.8 years

Step-by-step explanation:
Please help me out with my homework! This is super urgent! It's due in 18 minutes! Baranga lives in the city of Delmarville, North Carolina. She drives for 572 miles to Montgomery, Alabama. She drove for 22 hours. How long did she drive every hour?
Answer:
26 miles every hour
Step-by-step explanation:
she drove 572 miles for 22 hours
??????? for 1 hour
572/22= 26 miles per hour
Answer: 26 miles
We know that Baranga drove 572 miles in 22 hours. To find how much she drove every hour, we must divide.
Let m represent miles, and h represent hours.
m ÷ h = 26
Remember to always check your answer.
26 x h = m
Therefore, the answer is 26. Hope this helps you!
Suppose y varies directly as x. To solve you will need to find the constant of the
variation, write the equation so you can answer the question. If y = 4 when x = 2,
find y when x = 16.*
Answer:
32
Step-by-step explanation:
Given, y varies directly as x. So, y=kx, where k is the constant of proportionality.
Given, x=2, y=4. plug in the values in the equation.
4=k*2
k=4/2
k=2
x=16
y=2*16
y=32
Write the slope intercept form (y = mx + b) of the equation of the line through the given points with the given slope. Through:(2,-4), slope =-1
y = mx +c
Substitute the values,
-4 = -1(2) + c
c = -2
Thus, the equation is y= -x -2

The value of x is 0.57 in the given expression -0.8 x +40 - 8x -35
What is Expression?An expression is combination of variables, numbers and operators.
The given expression is -0.8 x +40 - 8x -35
Minus zero point eight times of x plus forty minus eight times of x minus thirty five
-0.8 x +40 - 8x -35
Add the like terms
-0.8x-8x+40-35
-8.8x+5
Isolate the variable x
-8.8x=-5
Divide both sides by 8.8
x=5/8.8
x=0.57
Hence, the value of x is 0.57 in the given expression -0.8 x +40 - 8x -35

Ron remembers that the second factor was a decimal. Based on the placement of the decimals in the first factor and the product, which must be true of the second factor? The decimal could be one-tenth. The decimal could be two-tenths. The decimal could be five-tenths. The decimal could be seven-tenths.
Answer: The decimal could be two-tenths.
Step-by-step explanation:
Two tenth as a product of decimals, 2/10 = 0.2. What this means is that a tenth is on of equal parts of something. e.g i received two tenth of the 30 bananas, what this implies is that he received 6 pieces of the bananas and this can be gotten by 2/10*30 = 6.

Katie went to buy a new tv and finds one for $550.00. In the state of Texas, there is a 6% sales tax on items. How much did Katie pay for the TV including the tax?
Answer:
583$

6% is equal to 0.06, so you multiply 550 by 0.06. which equals 33. Then, because it asks for how much Katie played, including the tax and TV, you add 33 to 550.

Think about the methods you have for comparing two probabilities to decide which is greater. In your Learning Log, create an example and explain two different strategies for comparing probabilities. Title this entry "Comparing Probabilities" and label it with today's date.
Answer:
Step-by-step explanation:
Probabilities are basically values determining how likely something is to happen. These values are usually represented in fractions or percentages which are the two main strategies as well for comparing probabilities. For comparing probabilities through fractions we would try to make sure the denominators are equal and then compare the numerators. The higher numerator is the probability with the highest chance of something happening. For example...
[tex]\frac{3}{4} > \frac{1}{4}[/tex] ... 3/4 is a much higher probability than 1/4
The second strategy would be using percentages in the same way. The higher percentage is the one with the highest probability while the lower percentage is the one with the lower probability.
96% > 54%
