We can figure out how many times a heart beats in one minute (so we can figure out how many minutes it will take for 140 times) by dividing 700 by 10. This gives us 70. Now we know that a heart beats 70 times each minute. Now we know it would take 2 minutes for a heart to beat 140 times because 70×2=140.
Two minutes is the answer.
Answer:
75 degrees
Step-by-step explanation:
let x unknown number
5x+10x+9x=180
24x=180
x=7.5
largest angle
10x
10×7.5=75
The answer is (1,2)
heres why:
(6,3)-(5,1)=(1,2)
so...
(1,2) is your answer to this problem
hope this helps
P.S.can u mark this as a brainliest answer plz
Answer:
m∠BEF = 65.3°
Step-by-step explanation:
Given:
m∠DEB = 27.2,
m∠DEF = 92.5
Required:
m∠BEF
SOLUTION:
Since B is the interior of ∠DEF, it means ∠DEB and ∠BEF are adjacent angles that make up ∠DEF. And they share the same side, BE.
Therefore:
m∠BEF + m∠DEB = m∠DEF (angle addition postulate)
m∠BEF + 27.2 = 92.5
Subtract 27.2 from each side
m∠BEF + 27.2 - 27.2 = 92.5 - 27.2
m∠BEF = 92.5 - 27.2
m∠BEF = 65.3°
Answer:
Step-by-step explanation:
so what you want to do is take -1/4x+2 3/4 and solve for x and once you got what x is plug it in to the second part 1/2^x +1
