I don't understand what you mean by 300 and 70, unless you meant 300/70 (in that case it would be 30/7). 


5/10 would be 1/5


8/100 would be 2/25.

Hello!

There are many other ways you can write these fractions. They are called "equivalent fractions".

Equivalent fractions mean the same thing as other fractions. You can get an equivalent fraction by either multiplying or dividing the numerator and the denominator of the fraction by the SAME number.

300/70 ÷ 10 = 30/7

So, 300/70 is equivalent to 30/7. You can also multiply by, say, 2.

300 × 2 = 600

70 × 2 = 140

So, 600/140 is also another fraction that is equivalent to 300/70.

5/10 is equivalent to 10/20, 15/30, 20/40, and many more fractions.

8/100 is equivalent to 4/50, 2/25, etc.

Abbey gets paid a flat rate of $10.00 to mow her neighbor's lawn plus an additional $5 per hour to rake the leaves.
sp2606 [1]

Answer:

Since you didn't provide any choices, a possible equations would be h = (m - 10) / 5

Step-by-step Solution:

Since we know that the flat-rate 10 doesn't have anything to do with the hourly rate, we first subtract that. Then, we divide that number by 5 to get rid of it, so we're only left with h.

This process of removing things from the equation by reversing their methods can be applied all over math and is a strategy vary commonly used.

timurjin [86]
Each angle on a triangle would add up to 180 degrees. Since a ladder goes straight up, that angle would be 90 degrees. If you add that with the 39 degree angle, you'd get 129. Subtract that from 180 and you have your answer.

Suppose that the IQs of university​ A's students can be described by a normal model with mean 140 and standard deviation 8 poi
AnnZ [28]

Answer:

0.0266, 0.9997,0.7856

Step-by-step explanation:

Given that the IQs of university​ A's students can be described by a normal model with mean 140 and standard deviation 8 points. Also suppose that IQs of students from university B can be described by a normal model with mean 120 and standard deviation 11. Let x be the score by A students and Y the score of B.

A)P(X>135) = \\P(Z>0.625)\\=0.0266

B) Since X and Y are independent we have

X-Y is Normal with mean = 140-120 =20 and Var (x-y)=Var(x)+Var(y) = 19

P(X-Y)>5\\\\=1-0.00029\\=0.9997

C) For a group of 3, average has std deviation = \frac{11}{\sqrt{3} } \\=6.351

P(\bar y >115)\\= P(z>\frac{-5}{6.351} \\=0.7856
