Let n = minutes since 12:00 pm when Malory catches up to Dori.
Dori travels
(50 steps/min)*(n minutes) = 50n steps
Malory begins walking at 12:20 pm, so she walks for (n - 20) minutes. She travels
(90 steps/min)*(n - 20 min) = 90n - 1800 steps
Equate the steps traveled by Dori and Malory.
90n - 1800 = 50n
40n = 1800
n = 45 min
The time corresponding to n = 45 min is 12:45 pm
Answer: 12:45 pm

Answer:
36 meters²
Step-by-step explanation:
Hassan built a fence around a square yard. It took 48 meters^2 of lumber to build the fence. The fence is 1.5 meters tall.
Let say square yard = x * x meters²
Perimeter of Square yard = 4x meters
Height of fence =1.5 meters
Area of fence = 4x * 1.5 =6x meters²
6x = 48
Divide both sides by 6
x = 8
Area of square yard = 6 × 6= 36 meters²
36 meters² is the area of the yard inside the fence
Answer:
f
Step-by-step explanation:
A right angled triangle has one angle equal to 90°
an obtuse angle triangle has one angle greater tan 90°
a) An o and right-angled triangle btuse angled triangle can have one angle equal.
b) R and O are not equivalent by definition
c) subset of R and Oare not all triangles as R and O are categories of all triangles. R and O are subset of all triangles
d) Acute triangles have all acute angles. So subset of R and O can't be all acute traingles
e) All triangles with two acute angles are may or may not have third angle as obtuse angle or 90° angle
f) none of the above
