Answer:
TRUE
Step-by-step explanation:
Two circles are congruent if they are equal in term of size. You can measure the size by comparing their diameter, radius or circumference. If two circles have the same radius, then they are said to be Congruent.
Therefore, the statement is TRUE ✅
Answer:
y = -5x - 19
Step-by-step explanation:
Find the y intercept using slope intercept form [ y = mx + b ]
y = -5x + b
-4 = -5(-3) + b
-4 = 15 + b
-19 = b
y = -5x - 19
Best of Luck!
Answer:
3.9 mi/h
Step-by-step explanation:
We assume that the given speeds are the speeds of the boats relative to the water. If c is the speed of the current, we have ...
time = distance/speed
47/(15 +c) = 40/(20 -c)
47(20 -c) = 40(15 +c) . . . . . . multiply by (20-c)(15+c)
940 -600 = 40c +47c . . . . . add 47c-600
340 = 87c . . . . . . . . . . . . . . . simplify; next divide by 87
c = 340/87 ≈ 3.9080 . . . . mi/h
The speed of the current is about 3.9 mi/h.
3400-480-2500=420
The answer is 420 millilitres
