1/4. Is the answer because 3:12 is not simplified divide it by 3 then you but the ration into a fraction which is 1/4
Step-by-step explanation:
3)
25% of 15.99=0.25×15.99=3.9975
Nope you will save about 4 dollars.
4)
12$ is 100% of its price
If there is a 25% discount, it will cost 75% of its original value.
75% of 12=0.75×12=9
It will cost 9 dollars
5)
You have 40% left of 150
so, 0.4(150)=60
You ANSWERED 90 but you still have <u>6</u><u>0</u> remaining.
6)
60% of 1350 lived since 40% died
0.6×1350=810
about 810 lived
7)
40% of the angelfish died
0.4×230=92
92 angelfish died
8)
The collected 125% of what they expected
1.25×1200=1500
They collected 1500 cans
4: B since the absolute value of a negative -3 would be 3 (equal)
5: C ( a good way to remember these is to picture the symbol as an alligator always trying to bite on the largest number)
7: D because 0.25 is not a whole number
8: A
9: A (using a calculator or pie chart is good to compare these values)
If you notice, the figure has two hexagonal faces and 6 rectangles.
now the rectangles are just 4x9 each, so their area is just 6(4*9) for all 6.
the hexagons has a
distance from the center perpendicular to a side of 7.8, namely the
apothem is 7.8, and since each side is 9 km long, the perimeter is 9+9+9+9+9+9.
since the area of a regular polygon is (1/2)(apothem)(perimeter), we can simply get the area of those two hexagons and the area of the rectangles, sum them up, and that's the surface area of the hexagonal prism.
Answer:
22/35
Step-by-step explanation:
-12/14=-6/7
-6/7*-11/15=66/105=22/35
