The width of the insect is 0.17 cm and the height of the insect is 0.125 cm.

Step-by-step explanation:

Step 1:

The scale factor is given by dividing the measurement after scaling by the same measurement

The given drawing of the insect is larger than the actual insect.

The scale factor is 20: 1 which means 20 cm on the drawing is 1 cm on the actual insect.

Step 2:

To obtain the actual insect's dimensions, we divide the dimensions of the drawing by 20.

The width of the actual insect = \frac{3.4}{20} = 0.17.

The height of the actual insect = \frac{2.5}{20} = 0.125.

The width of the insect is 0.17 cm and the height of the insect is 0.125 cm.

Which algebraic expression represents the phrase below? five times the sum of a number and eleven, divided by three times the su
Umnica [9.8K]
The phrase has two parts:

Five times the sum of a number and eleven, divided by three times the sum of the number and eight

Let the number be x. Five times the sum of a number and eleven means 5 multiplied to the sum of x and 11. In expression this will be written as:

5(x + 11)

Three times the sum of the number and eight means 3 multiplied to the sum of x and 8. In expression this will be written as:

3(x + 8)

So, the overall expression will be:

\frac{5(x+11)}{3(x+8)}

kozerog [31]

Answer:

Out of 450 phones 18 of them will have a defect.

Step-by-step explanation:

As we know that out of 75 phones 3 of them will have a defect, this means that we are able to calculate how many defects there will be from 450 phones. You can do this by first dividing 450 by 75, this gives you 6. This means that 75 will go into 450 6 times.

From this we are able to work out the number that will have defects. This is because we know that 75 goes into 450 6 times and that for each 75 phones there will be 3 defects. So to work out the number of phones out of 450 that would be defects you would simply multiply 3 by 6, this gives you 18. This shows that out of 450 phones 18 of them will have a defect.

1) Divide 450 by 75.

450/75=6

2) Multiply 6 by 3.

6*3=18
