Answer:
Hey there!
Pythagorean Theorem: a^2+b^2=c^2
16+25=c^2
41=c^2
c=6.4
Let me know if this helps :)
Answer:
the value of x is 12, the answer is C, x = 12
1/2DF = EF
1/2(2y) = 8y - 3
y = 8y - 3
- Subtract 8y from both sides.
-7y = -3
y = 3/7
- Plug 3/7 for y into DF and EF.
DF: 2(3/7) = 6/7
EF: 8(3/7) - 3 = 24/7 - 3 = 3/7
EF = DE because they are bisected, so DE = 3/7
Answer:
2 hours 30 minutes
Step-by-step explanation:
Step one
Given data
The total distance to be covered= 20miles
Priya runs at a constant speed of 6 miles an hour
Hence Her speed = 6mph
Jada walks at a constant speed of 2 miles an hour
Hence Her speed = 2mph
let the time taken by them to cover the distance be t
Step two:
from speeed= distance/time
distance= speed*time
so
20=6*t+2*t
20= 6t+2t
20=8t
divide both sides by 8
t= 20/8
t=2.5 hours
That is, it wiil take them 2 hours 30 minutes to meet
The reason is because, the distances covered by them must sum up to 20 miles
Answer:
The answer to your question is leg 2 = 0.9 in
Step-by-step explanation:
Data
Leg 1 = 4 in
hypotenuse = 4.1 in
Leg 2 = ?
Process
To solve this problem use the Pythagorean theorem, solve for leg 2 and simplify to get the result.
Pythagorean theorem
c² = a² + b²
or hypotenuse² = leg 1² + leg 2²
-Solve for leg 2²
leg 2² = hypotenuse² - leg 1²
-Substitution
leg 2² = 4.1² - 4²
-Simplification
leg 2² = 16.81 - 16
leg 2² = 0.81
leg 2 = 0.9 in
