Answer:
The hight length : h
The base length : a
Apply the Pythagorean theorem in the right triangle :
h² = 13² - (10/2) = 144
h = √144 = 12 cm
S = (a x h)/ 2 = ( 10 x 12 )/2 = 60 cm²
Step-by-step explanation:
Answer: C
Step-by-step explanation:
The answer is 2 buckets
Explain:
Tim picked 1 7/12 and Fred picked 4 2/3
These as improper fractions are 19/12
And 8/3
To make these have the same denominator you would times the 8/3 by 4 to give 32/12
Take these two away, Fred has 13 more apples.
And as we calculated it with there being 12 in each bucket there would be one full bucket but we would need another bucket for the apple left
So Fred picked 2 more buckets than Tim.
Hoped it makes sense and that I helped
Answer:
the second choice
Step-by-step explanation:
The base is 9 units and the height is 4 units.
The two cars will meet when the sum of the distances covered by the two cars is 330 kilometers.
distance = speed x time.
Let the time covered when they meet be x, then:
80x + 85x = 330
165x = 330
x = 330/165 = 2 hours.
In 2 hours, the canary will cover 90 x 2 = 180 kilometers.
Therefore, the has flown 180 kilometers when the cars collide..
