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.

uysha [10]

The correct answer for the question that is being presented above is this one: " Your trying to figure out what is 48 percent of 70 because that's how much Adam's sister is going to eat at dinner. So your is would be 48 and your of is 70. When you substitute those numbers your formula becomes 48/70=x/100. Now you cross multiply and get 70x=4800.All that's left is to divide 70 on both sides. Which gives you 68.57.The final answer is 69 percent."

Lexi has already jarred 19 liters of jam and will jar an additional 9 liters of jam every day. How many days does lexi need to s

Marysya12 [62]

Answer:

Lexi need to spend 6 days to fill the jar with 73 liters of jam.

Step-by-step explanation:

Given:

amount of jam already had in jar =19 liters

amount of jam added each day in jar = 9 liters.

Total number of jam to be needed in jar = 73 liters.

We need to find the number of days required to jar 73 liters.

Solution:

To find the number of days required to jar 73 liters will be equal to amount of jam already had in jar plus amount of jam added each day in jar multiplied by number of days.

framing in equation form we get;

$19+9x= 73$

Subtracting both side by 19 we get;

$19+9x-19=73-19\\\\9x = 54$

Dividing both side by 9 we get;

$\frac{9x}{9}=\frac{54}{9}\\\\x=6\ days$

Hence Lexi need to spend 6 days to fill the jar with 73 liters of jam.
