Answer:
Step-by-step explanation:
Use Pythagoras’ theorem
square of hypotenuse = sum of squares of two other sides
let the missing side be d
30^2 = 20^2 + d^2
600 = 400 + d^2
d^2 = 200
d = square root of 200
d = 14.142 cm
All you do is divide.
330/390= 0.846
round it: 0.85
Answer is about 85%
The formula for the sum of the a finite geometric series is this:
Sn = a((1-r^n) / (1-r))
The given values are:
n = 30
a = 0.5 mi
r = 1.10 (10% more each day)
S30 = 0.5 ((1-1.10^30) / (1-1.10))
S30 = 82.25 mi
After 30 days, he will have traveled 82.25 miles.
Tip: If you’re not sure on answers for I-Ready, just turn off your WiFi, pick the answer you think is right and yeah! If you get it wrong, click “Next” and it’s gonna load load and then there’s gonna be a bar on the top and click that, then it’s gonna show you something to tell your teacher, after it said that, turn back on your WiFi and you’re still at the same spot! reply back if you didn’t understand since I am rushing.
Answer:
The following measurements are:
(Option #4)
(Option #7)
(Option #5)
(Option #2)
Step-by-step explanation:
To begin, we can find the measure of 
by applying the inscribed angle theorem: an angle θ inscribed in a circle is half of the central angle 2θ that subtends the same arc on the circle.
Since the intercepted arc (RS) is 46 degrees, we have:
Next, we can find the measure of arc QT using the same theorem. So,
Notice that the chord RT is actually a diameter. From the theorem about the inscribed angle including a diameter, we know that the intercepted arc will have a measure of 
. Since the arc ST is part of the arc RST, and we know RS is 
, we can set up and solve this equation:
We can use the same idea to find RQ. We know that RQT is and QT is 
, so:
