One positive number is 8 more than twice another. If their product is 234 find the numbers
Setler [38]

Answer:

Step-by-step explanation:

Let the larger number = x

Let the smaller number = y

x = 2*y + 8

x * y = 234              Put the first  equation into the second.

(2y + 8)*y = 234      Remove the brackets

2y^2 + 8y = 234     Subtract 234 from both sides

2y^2 +  8y - 234 =0 Factor out 2

2(y^2 + 4y - 117) = 0 Divide by 2

y^2 + 4y - 117 = 0

(y + 13)(y - 9)

y = 9 is one answer

x * y = 234

x * 9 = 234         Divide by 9

x = 234/9

x = 26

The two numbers are 9 and 26

Points R, S, and T are collinear, and S is between R and T. Find ST if RS = 6.4in and RT = 9.3 in.
babymother [125]

Answer:

Step-by-step explanation:

The layout looks like this.

r-----------s-----------------t

    6.4        

----------------9.3-----------

Now you want st so the formula is

rt = rs + st

9.3 = 6.4 + st            Subtract 6.4 from both sides

9.3 - 6.4 = st             Combine

st = 2.9

A mechanic sells a brand of automobile tire that has a life expectancy that is normally​ distributed, with a mean life of 27 com
Harrizon [31]

Answer:

Tires that wear out by approximately 24307.8 miles will be replaces free of charge.        

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 27,000 miles

Standard Deviation, σ = 2100  miles

We are given that the distribution of life expectancy is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

We have to find the value of x such that the probability is 0.10

P( X < x) = P( z < \displaystyle\frac{x - 27000}{2100})=0.10  

Calculation the value from standard normal z table, we have,  

\displaystyle\frac{x - 27000}{2100} = -1.282\\\\x = 24307.8

Tires that wear out by approximately 24307.8 miles will be replaces free of charge.
