Answer:
x/4 > 9
Step-by-step explanation:
brainly.com/question/2530631 Hey its me again. I answered this question of yours and coincidentally I found you again. ^-^
The first shape seems to be scaling up. From 3cm to 12cm. So for this you need to multiply. Using the formula that I gave you last time. 3cm times ___ = 12cm. 4 fits in there, therefore 6cm^2 times 4 = 24cm^2.
The answer for the first one would be 24cm^2. "24" in the blank.
The second shape seems to be scaling down. From 16cm to 8cm. So for this you need to divide. 16cm divided by ___ = 8cm. 2 fits in there, therefore 40cm^2 divided 2 = 20cm^2.
The answer for the second one would be 20cm^2. "20" in the blank.
The third shape seems to be scaling up. From 3cm to 4.5cm. So for this you need to multiply. 3cm times ___ = 4.5cm. Now since we're dealing with decimals, not whole numbers this time you can't really use guess and check as efficiently. So you do the opposite operation, which in this case the opposite of multiplication is division. You take 3cm (the original shape's number) and divide it into 4.5cm. So 4.5cm divided by 3cm = 1.5. 1.5 fits in there, therefore 20cm^2 times 1.5 = 30cm^2.
The answer for the third one would be 30cm^2. "30" in the blank.
First, to rewrite something in scientific notation, we want to move the decimal point a number of times to the right or left to end with a number between 0 and 10. In this case, we want to move the decimal point 7 times to the left to get the number 1.304. In scientific notation, this would be the same as 1.304*10^7.
I hope this helps!
Answer:
132 patches
Step-by-step explanation:
First we need to find the area of the rectangular piece, multiplying the length and the width:
Area of fabric: 10 * 6 = 60 cm2
If each triangular patch has 15 cm2 of area, a fabric of 60cm2 can make 60 / 15 = 4 triangular patches.
Then, if Leia uses 33 pieces of fabric, she can make a total of 33 * 4 = 132 patches.
