Answer: c)She should have multiplied 15 by 3 instead of dividing.
Step-by-step explanation:
Number of quilts Ruby plan to make in one month= 3
which means if Ruby makes more than 3 quilts, the time will be more than 1 month.
To find the number of months to make 15 quilts, she need to divide 15 by 3
Thus, the number of months to make 15 quilts=5
Her answer was 1/5 which was absolutely wrong as if she is making 3 quilt in 1 month then in 1/5 month she would make fewer than 3 quilts.
She divides 3 by 15 instead of 15 by 3, thus but the unit is quilts not months.
Thus the only wrong option is c)She should have multiplied 15 by 3 instead of dividing.
Answer:
B) Chemical Change
Step-by-step explanation:
Physical change only changes the physical appearance of good, their chemical properties remaining same. These are usually reversible. Eg : Cutting a cake
Chemical change changes the physical composition of the product(s) involved. These are usually not irreversible. Eg : Baking of a cake, getting bubbles during bake process meanwhile
Perimeter= measurement around the shape. 15+22+10+18+14=79. The perimeter of the polygon is 79ft.
The answer to your question is 3 to the 3rd power and 5 to the 2nd power. The reason why that's your answer is because there are three 3s so instead of doing 3*3*3 you can just simply do 3 to the 3rd power and do the same thing to the 5. You can see that there are two fives so you do 5 to the 2nd power.
Hope this helps:)
Answer:
(2x +5) + 3x = 90
5x + 5 = 90
5x = 85
x = 17
