Answer:

1.3125 gallons

Step-by-step explanation:

Using the given information, we can set up a proportion;

\frac{2.1gallons}{1.6minutes} = \frac{xgallons}{1minute}

Now, we can cross multiply to solve for x.

2.1 = 1.6x
x = 1.3125 gallons

Answer:  1.3125 gallons

Step-by-step explanation: The machine pumps 2.1 gallons of water every 1.6 minutes. 1.6 minutes is 1.6x more than 1 minute. So, we have to divide 1.6 by 1.6. Next, we have to divide 2.1 by 1.6. We can make this a bit easier by multiplying both of them by 10 to get 21/16 which is 1.3125.

Given the exponential equation 2x = 128, what is the logarithmic form of the equation in base 10?
max2010maxim [7]

Answer:

log_{2}128= \frac{log_{10} 128}{log_{10} 2}.  

Step-by-step explanation:

Given : 2^{x} = 128.

To find :  what is the logarithmic form of the equation in base 10

Solution : We have given that 2^{x} = 128.

By th change base rule ( inverse of exponential function )

a^{b} = c is equal to  log_{a}(c) = b

Then 2^{x} = 128 in to logarithm form  log_{2}(128) = x.

Then in to the base 10 logarithmic form.

By the change of base formula log_{b}a= \frac{log_{10} a}{log_{10} b}.

Then , log_{2}128= \frac{log_{10} 128}{log_{10} 2}.  

Therefore, log_{2}128= \frac{log_{10} 128}{log_{10} 2}.

Argyle sells computers. He keeps one
Tomtit [17]

Answer:

Note: I'm assuming that he keeps 1/8 of the money spent for himself.

If this is what the question was asking, then the answer would be:

Argyle must sell $4,000 worth of computers.

Step-by-step explanation:

First, we write an equation.

1/8n = $500

Note: n is the variable I'm using to represent the amount of money Argyle must sell to get $500 as commission.

Then, to get the value of n and to get rid of the fraction, we multiply both sides by 8:

1/8n * 8 = $500 * 8

= n = $4000

Therefore, Argyle must sell $4,000 worth of computers to keep 1/8 ($500) as commission.

The multiples of 4 have an even number in the tens place.What values do they have in the ones place? With multiples of 4 that ar
4vir4ik [10]

Answer:

0 , 4 , 8

Step-by-step explanation:

Multiples of 4 = 12,16,18,20, 24, 28.............100, 104, 108, 112, 116,120, 124, 128

Numbers that have even no. in tens = 20, 24 , 28 ... 100, 104, 108, 120 , 124, 128

As evident, all these numbers (including those > 100) have 0, 4, 8 as one's place numbers.
