Answer: 2,400 doctors used brand X aspirin.
Step-by-step explanation: The question notifies us that 3,600 total doctors were surveyed. This automatically lets us know that 6/6 doctors = 3,600 doctors. We can find the unit rate from this point by dividing 3,600 by 6. We will find that 600 doctors represents 1/6 doctors. We can multiply our unit rate by 4 to find that 4 out of 6 doctors, or 2,400 doctors, use brand X aspirin. 4/6 of 3,600 is 2,400, so 2,400 doctors used brand X aspirin. Hope this helps!
The next number in the sequence will be 129.
2x + 5y = 5
5y = 5 - 2x
y = (5 - 2x)*(1/5)
y = 1 - 2/5x
y= -2/5x + 1
--------
This means that 2x+5y=5 is a line of the form y=mx+C, whereby m=-2/5 and C=1.
When x=0,
5y=5
y=5/5
y=1.
FIRST COORDINATE (0,1)
When y=0,
2x=5
x=5/2
x=2.5
SECOND COORDINATE (2.5, 0)
Draw a line through the coordinates (0,1) and (2.5, 0) and your graph will emerge.
Answer:
m∠QRS = 52°
Step-by-step explanation:
From the given figure,
In right triangles ΔRQT and ΔRST,
QT = TS = 7.5 units [Given]
RT ≅ RT [Reflexive property]
ΔRQT ≅ ΔRST [By HL theorem of congruence]
Therefore, m(∠QRT) = m(∠SRT) = 26° [CPCTC]
m(∠QRS) = 2m(∠QRT)
= 2×(26°)
= 52°
