EASY PUZZLE FOR FUN! YOU WILL GET LOTS OF POINTS AND BRAINLIEST!!!! This is a crypt-arithmetic puzzle! it goes like this! S E V

E N + S E V E N + S E V E N + N I N E = T H I R T Y, each letter represents a number, and you can only use numbers 0-9, meaning 0 and 9 can be used too, no double digit numbers! For example: S can mean 7, and there is 3 S's, meaning 7x3=21, you cannot use decimals, only whole numbers. And you cannot use the same number for two types of different letters. As you can see thirty is the final answer, each letter in thirty is a number! Meaning you would have to either use high numbers or come up with something! For example: there is 6 letters in thirty, meaning, you will use 5 numbers since there is 2 T's, for example 9,8,7,6,5. Thirty=40, you will have to use the letters in the 3 SEVEN and 1 NINE words and turn them into numbers, example: S=1, meaning, 1x3=3, you get the idea. Good luck!

Answer:

This question is very tricky but i think i got it right. so first i tried making all the s's into sevens but that didn't work since it just adds up to a lower value. So i tried looking at it from another angle. This time i added the e's together to make 9 i forgot what were the e's but the fraction i came up with just didn't add up. Then i read the question again it said i cant add from 0-9 i thought i could only add from 0-5 this changed everything. I tried again and i came up with my final answer: (estimation) <u>250???</u>

Choose the property used to rewrite the expression. log618-log66 = log63.a) Commutative Propertyb) Product Propertyc) Power Prop
n200080 [17]

Answer:

Option d) is correct

ie, quotient property

Step-by-step explanation:

Given expression is log 618-log 66=log 63

Now we take log 618-log 66

log 618-log 66 = log \frac{618}{66} [By using quotient property, log\frac{x}{y}=\log x- \log y]

= log 63

Therefore log 618- log 66= log 63

Option d) is correct

In the given expression we are using the quotient property

Which number line correctly shows –0.8 + 0.6? A number line going from negative 1.6 to positive 1.6. An arrow goes from negative
Phoenix [80]

Answer:

Hi there, are you sure you didn't forget any parenthesis or signs? I can't find the right answer in the options, the one that would end up at -0.2 in the end I can edit my answer if you tell me some additional option or info about the expression I need to show on the number line

Step-by-step explanation:

which number line shows correctly -0.8 + 0.6?

well lets write it in words minus eight tenths plus six tenths\

so minus:

you go 0.8 units to the left from 0,

then plus:

you go 0.6 units right from -0.8, getting to -0.2

since there is no exact answer like that we can rearrange the addends 0.6-0.8, now:

we go from 0 6 tenths units to the right and get to 0.6, then we go from 0.6 eight tenths unit to the left to get to -0.2

In analyzing the city and highway fuel efficiencies of many cars and trucks, the mean difference in fuel efficiencies for the 60
Olegator [25]

Answer:

7.38-1.96\frac{2.51}{\sqrt{601}}=7.18    

7.38+1.96\frac{2.51}{\sqrt{601}}=7.58    

For this case the confidence interval is given by :

7.18 \leq \mu \leq 7.58

Step-by-step explanation:

Data provided

\bar X=7.38 represent the sample mean for the fuel efficiencies

\mu population mean

s=2.51 represent the sample standard deviation

n=601 represent the sample size  

Confidence interval

The formula for the confidence interval of the true mean is given by:

\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}   (1)

The degrees of freedom for this case is given by:

df=n-1=601-1=600

The Confidence level for this case is 0.95 or 95%, and the significance level \alpha=0.05 and \alpha/2 =0.025 and the critical value is given by t_{\alpha/2}=1.96

Replcing into the formula for the confidence interval is given by:

7.38-1.96\frac{2.51}{\sqrt{601}}=7.18    

7.38+1.96\frac{2.51}{\sqrt{601}}=7.58    

For this case the confidence interval is given by :

7.18 \leq \mu \leq 7.58

A motorcycle can travel 60 miles per gallon. Approximately how many gallons of fuel will the motorcycle need to travel 40 km?
Semenov [28]
The first thing to note is since one gallon= 60 miles then 1/2 gallon= 30 miles, now I know 1/2 is not an answer but it is easiest to decrease in moderate amounts. 1/2 gallon= 48 Km so we are close, and 1/2=0.5 so if we brought it down to 0.42 we would have 25.2 miles and 25.2 miles = 40.32. The question wants to know the approximate number and 40.32 is the closest we are going to get so the answer is 0.42
