After solving 1.32:3 \frac{1}{7}=(1.4y):\frac{5}{6}  we get y=0.24

Step-by-step explanation:

We need to solve the ratio: 1.32:3 \frac{1}{7}=(1.4y):\frac{5}{6} and find value of y

Solving:

1.32:3 \frac{1}{7}=(1.4y):\frac{5}{6}

Converting fractions into decimals

1.32:3.14=(1.4y):0.83

Ratio can be written as:

\frac{1.32}{3.14}=\frac{1.4y}{0.83}

Now cross multiply

1.32*0.83=1.4y*3.14

1.09=4.39y

y=\frac{1.09}{4.39}

y=0.24

So, after solving 1.32:3 \frac{1}{7}=(1.4y):\frac{5}{6}  we get y=0.24

You are at the bottom of a mountain where the temperature is 74°F. The top of the mountain is 5500 feet above you. What is the t
mamaluj [8]

For every 1,000 feet you go up in elevation, the temperature decreases by about 3.3°F

 

Given:

Temperature at the bottom of the mountain is 74°F

The top of the mountain is 5500 feet above you

 

Change (reduction) in temperature is 3.3 X 5500 / 1000

= 18.15°F

 

Temperature at the top of the mountain is 74°F – 18.15°F

= 55.85°F

Suppose that 3% of all athletes are using the endurance-enhancing hormone EPO (you should be able to simply compute the percenta
trapecia [35]

Answer:

Step-by-step explanation:

So there is a 3% probability that an athlete is using EPO .

The probability of showing positive on a test when you've used it is 0.99.

3% x 0.99= 2.97%

The probability of a positive result without EPO is 0.1

97% x 0,1 = 9,7 %

My guess is that 2.97% + 9,7% = 12.67% or 0.1267.

I don't know i may be wrong because you've put as an answer 0.0297 but if you like you may take only the first part of the answer.

A new obstacle course is home to several new types of challenging obstacles. One such obstacle is traversing a 15-stair staircas
Tresset [83]

Answer: 22\frac{1}{2}\text{ Feet}

Step-by-step explanation:

Here, the vertical space between two consecutive stairs in first 10 stairs = 1\frac{1}{3}\text{ feet}

⇒ The total vertical distance for 10 stairs = 10\times 1\frac{1}{3}=10\times \frac{4}{3}=\frac{40}{3}\text{ feet}

Also, The vertical space between two consecutive stairs for last 5 stairs = 1\frac{3}{4}\text{ feet}

⇒ The total vertical distance for 10 stairs = 10\times 1\frac{1}{3}=5\times \frac{7}{4}=\frac{35}{4}\text{ feet}

Thus, The total vertical distance = Total vertical space for the first 10 stairs + Total vertical space for the last 5 stairs

= \frac{40}{3} + \frac{35}{4}

= \frac{160+105}{12}

= \frac{265}{12}

= 22\frac{1}{2}\text{ Feet}

Part of a book fell out. The first page of this part has number 143. The last page has a number written with the same digits. Ho
Gnom [1K]

Answer:

142 pages

Step-by-step explanation:

The parameters given are

First page of part of the book available = 143

The last is numbered with the digits 143

Since the book is said to have been split into two parts with, we have that one part of the book starts from the beginning, while the other part continue from the first part stops

Number on the pages on the first part = from 1 to number on the first page on the second part - 1

Hence, the part of the book available is the second part and the number of pages in the first part = 1 to 142 or 142 pages.
