Among the options provided, the statement that holds true is the third one: "Nina makes 20x dollars each week at the clothing store." The information given explicitly mentions that x denotes the total hours she has worked within a week. This assertion renders the other statements incorrect.

A building casts a shadow 25 m long. At the same time, the shadow cast by a 44-cm tall pole is 59 cm long. Find the height of th
Inessa [12570]

In order to solve this, we will use proportions. The first step involves converting centimeters to meters by applying dimensional analysis:

\frac{44\ cm}{1}*\frac{0.01\ m}{1\ cm}=\frac{0.44}{1}=0.44\ m

\frac{59\ cm}{1}*\frac{0.01\ m}{1\ cm}=\frac{0.59}{1}=0.59\ m

Once everything is expressed in meters, we can set up the proportions accordingly. Our proportion becomes \frac{x}{25} =\frac{0.44}{0.59}

First, we perform cross-multiplication: 0.59x=11

Then, by dividing both sides by 0.59, we arrive at x = 18.6 m, or D.

A tennis coach divides her 9-player squad into three 3-player groups with each player in only one group. How many different sets
PIT_PIT [12445]

Answer:

3

Step-by-step explanation:

The coach organizes her 9 players into groups of 3. Therefore, she has a total of 9 players and wants to group them in sets of 3.

To determine how many groups of three can be formed, we divide the total players by 3. This gives us:

9 / 3 = 3 groups

Thus, there will be 3 groups of 3 players each.

The smallest natural number divisible by 2,3,4,5,6,8 and 9 is____.
Zina [12379]

Response:

360

Explanation in steps:

You'll require 2 * 2 * 2 to ensure the smallest number is divisible by 8 along with all the others.

For the smallest number to be divisible by 9 along with the others, 3 * 3 is necessary.

Ultimately, you'll need 1 five

Thus, the smallest number divisible by all these factors is calculated as 2*2*2*3*3*5 = 360

  • 360/2 = 180 is valid
  • 360/3 = 120 is valid
  • 360/5 = 72 is valid
  • 360/6 = 60 is valid
  • 360/8 = 45 is valid
  • 360/9 = 40 is valid.

No smaller number than 360 fulfills this requirement.

The solution generated by the calculator is 5.779E-8. Describe how to interpret the solution.
lawyer [12517]

Answer: The 'E' signifies scientific notation. The initial number serves as the coefficient in scientific representation, multiplied by a power of ten. The figure trailing the 'E', which is -8, denotes the exponent, while the base is 10.
