<span>This distance would be written as a whole number as 93,000,000. To get this number, you would use the first two numbers and then add 6 zeros to the end to account for the 10^6. 10^6 is equal to 10 multiplied by 10 six times with each product being multiplied by 10. This can also be displayed as 1E6. This number is then multiplied by 93 to get 93,000,000.</span>

For this case we have the number in exponential notation:

93 * 10 ^ 6

We observe that the exponent of the exponential notation is positive.

Therefore, to express the number as a whole number, we must move the comma 6 spaces to the right.

We have then:

93 * 10 ^ 6 = 93,000,000

Answer:

this distance written as a whole number is:

93 * 10 ^ 6 = 93,000,000 miles

A plumber had two pipes. The ratio of the length of the longer pipe to the shorter pipe was 9:2. When he cut 1.65m from the long
Natasha2012 [34]

Answer:

1.1m

Step-by-step explanation:

Let L denote longer pipe and S denote shorter part

given:

L:S = 9:2

or L/S = 9/2

2L = 9S

S = (2/9)L-----(eq 1)

Also given:

L - 1.65 = 3S

L - 3S = 1.65 ----- (eq 2)

By substitution, sub eq 1 into eq 2

L - 3(2/9)L = 1.65

L - (2/3)L = 1.65

L [ 1 - (2/3) ] = 1.65

L/3 = 1.65

L = 1.65 (3) = 4.95  (substitute into equation 1)

S = (2/9)(4.95) = 1.1m

Write the sum of 32+20 as the product of their GCF and add another sum
vladimir2022 [97]
The factors of  32  are  1,  2,  4,  8,  16, and  32.

The factors of  20  are  1,  2,  4,  5,  10, and  20.

The common factors of  32  and  20  are  1,  2, and  4.

The greatest one is 4.

32 = 4 x 8

20 = 4 x 5

32 + 20 = (4 x 8) + (4 x 5)

32 + 20  =  <em>4 (8 + 5)</em>

A manufacturer of pickup trucks is required to recall all the trucks manufactured in a given year for the repair of possible def
Dafna11 [192]

Answer: Probability of trucks having both defects is 4%.

Step-by-step explanation:

Since we have given that

Probability of trucks having defective brake linings only = 6%

Probability of trucks having defective steering only = 3%

Probability of trucks having neither defect = 87%

Probability of trucks having either defect - 100 - 87 = 13%

Let the probability of trucks having both defects be 'x'.

P(defective brake lining) = P(B) = 0.06+x

P(defective steering) = P(S) = 0.03+x

So, Probability of the trucks having both defects is given by

P(S\cup B)=P(S)+P(B)-P(S\cap B)\\\\0.13=0.03+x+0.06+x-x\\\\0.13-0.03-0.06=2x-x\\\\0.04=x

So, Probability of trucks having both defects is 4%.

Mumz [18]

Answer:

For cobalt-60, which has a half-life of 5.27 years, 50% remains after 5.27 years (one half-life), 25% remains after 10.54 years (two half-lives), 12.5% remains after 15.81 years (three half-lives), and so on.

Step-by-step explanation:

You can figue out the rest.
