Step-by-step explanation:
There are 24=16 total possible outcomes of which only one outcome gives rise to all heads. Thus the probability that all coins land heads is 1/16.
The perimeter of a triangle has the formula 2l + 2w. Since the length is twice as long as the width, l = 2w. We use this equations to two possible perimeters, 90 and 120 feet.
P = 90 feet
90 = 2(2w) + 2w
90 = 6w
w = 15 feet
P = 120 feet
120 = 2(2w) + 2w
120 = 6w
w = 20
Thus, the range of w is from 15 to 20 feet. The answer is <span>15 ≤ w ≤ 20</span>
My answer is A, hope it helps you
The ratio of Julia's to Vlada's peas was 3:2.
1. Julia gave Vlada 15 peas.
2. Vlada had how many peas?
3. Vlada had 4:2 peas after Julia gave her 15 more peas. (3:2+15=4:2)
4. Julia still had 15 more than Vlada.
5. Julia had 5:7 because (4:2+15=5:7)
6. To find out the amount of peas she had BEFORE she gave Vlada the peas, you subtract 5:7 from 15. That would equal 4:2.
