Answer:
Step-by-step explanation:
Let's put in some numbers to make this easier to understand.
Let's say she has to travel 20 km.
On Monday, she travels at 4 kph. This takes 5 hours.
On Tuesday she travels 25% faster, at 5 kph. This takes 4 hours.
To figure percent reduction we take
100 % * (old - new) / old
100 % * (5 hr - 4 hr ) / 5 hr
100 % * 1 hr / 5 hr
100 % * 0.20
20% reduction.
Answer:

Step-by-step explanation:
Given:
An isosceles triangle ABC with AB = AC.
∠A = 
∠B = 
∠C = 
We know that, for an isosceles triangle, the angles opposite equal sides are also equal to each other.
Therefore, ∠B = ∠C
⇒ 
⇒ 
∴ ∠C =
°
Now, the sum of all the interior angles of a triangle is always 180°.

Therefore, the value of 'y' is 5.
Answer:20cm
Step-by-step explanation:
Circumference=20π
Diameter=circumference ➗ π
Diameter=20π ➗ π
Diameter=20
Diameter=20cm
Answer:
1.50 + 13.75 = 15.25
15.25 x 579.50 = 38
ok so basically you take the total and divide it by the total of one student!! :)
answer is: 38
