Answer: 62

Step-by-step explanation: Set up your equation

21+x=2x-41 because the number (x) that 21 is added to is 41 less than (so subtraction) twice (so multiply the number x by 2) the number (x).
Get the x's on one side by subtracting the single x
21=x-41
Now add 41 to both sides to completely isolate x
62=x
So, your answer is x=62. The number is 62.

Check your work. 62+21=83. 2(62)= 124. 124-41=83. Both equations equal 83, so the solution is correct.

Answer:

0.150,0.595

Step-by-step explanation:

Given that at a self-service gas station, 40% of customers pump regular gas, 35% pump midgrade, and 25% pump premium gas. Of those who pump regular, 30% pay at least $30. Of those who pump midgrade, 50% pay at least $30. And of those who pump premium, 60% pay at least $30.

Regular gas Midgrade Premium gas Total

Percent 40 35 25 100

atleast 30 30% 50% 60%

a) The probability that the next customer pumps premium gas and pays at least $30

= $0.25*0.60\\=0.150$

b) the probability that the next customer pays at least $30

= P(regular and pays atleast 30%)+P(premium and pays atleast 30%)+P(midgrade and pays atleast 30%)

= $0.40*0.30+0.35*0.50+0.25*0.60\\=0.12+0.175+0.30\\=0.595$

What is the maximum number of pages the report can have so that it can be completely stored on a USB drive that holds 4 \cdot 10

lana [24]

Answer:

2,300,000pages report.

Step-by-step explanation:

Given a USB drive with memory of 4.6*10⁶KB, in order to know the maximum number of pages a report can have so that it can be completely stored on the drive, the conversion factor must be used.

We must first understand that 1 page of a document uses up approximately 2kB of the storage.

Since 2kB = 1page

4.6*10⁶KB = x page

Cross multiply

2kB * x = 4.6*10⁶KB * 1

2x = 4.6*10⁶

x = 4.6*10⁶/2

x = 2.3*10⁶

x = 2,300,000

Hence the maximum number of pages that the report can have so that it can be completely stored on a USB drive that holds 4.6*10⁶KB is approximately 2,300,000pages report.
