Answer:
D. 108 liters
Step-by-step explanation:
Given that the leak is ;
5 drops = 5 minutes
?= 4 weeks
Find number of hours in 4 weeks
1 week=7days
4 weeks=?--------------cross multiply
4×7=28 days
1 day=24 hours
28 days=?--------------cross multiply
28×24=672 hours
Hour= 60 minutes
672 hours=?
672×60=40320 minutes
Finding the leakage in 4 weeks
80 drops= 5 minutes
?=40320 minutes------------cross multiplication
(40320×80)÷5 =645120 drops
Finding the liters of water wasted in 4 weeks
60 drops of water= 10 milliliters
645120 drops of water=?-------------cross multiply
(645120×10)÷60 =107520 milliliters
But you know
1 milliliter=0.001 liters
107520 milliliters=?-----------cross multiply
107520×0.001
=107.52 liters
=108 liters
Answer:
i believe its the second choice
Step-by-step explanation:
(-2,-6)
Answer:
A. no
B. see below
C. KL = 14
Step-by-step explanation:
A. AA similarity requires two angles in one triangle be congruent with two angles in the other. Here, only one angle is marked in each triangle, so AA similarity cannot apply.
__
B. See the explanation given in Part A.
__
C. The triangles are similar because corresponding sides are proportional (and the angle between them is congruent). The sides that correspond are the ones on either side of the marked angle. The sides in the larger triangle JKL are double the measure of the sides in the smaller triangle GHI. Hence, for HI = 7, KL = 2·7 = 14.
Treat the vowels like they are 1 block, as if they are one letter. But in this vowel block there are 4 vowels, 2 of which are the same. The number of ways of arranging these 4 vowels is then <span><span><span>4!</span><span>2!</span></span><span><span>4!</span><span>2!</span></span></span>.
Now, treating this block aa one letter, we have 7 consonants and 1 block, so there are 8 'letters' to arrange with two M's and two T's. So we have to divide out by 2! for each. So we get: <span><span><span>8!</span><span>2!2!</span></span><span><span>8!</span><span>2!2!</span></span></span>.
Finally we multiply this by the number of ways the vowels can be arranged to get:
<span><span><span>4!</span><span>2!</span></span><span><span>8!</span><span>2!2!</span></span></span>
