The diameter is approximately 32.72 cm.
Answer:
The value of 
which makes the equation true.
Step-by-step explanation:
Given the equation
We have to find the value of r for which the equation must be true.
solving the equation
Multiply both sides by -11
Therefore, the value of which makes the equation true.
<u>VERIFICATION:</u>
Putting in the equation
∵
L.H.S = R.H.S
Therefore, the value of which makes the equation true.
Answer:
t=4h
Steps below
Step-by-step explanation:
We know:
speed of boat with respect to earth: 13 km
speed of stream with respect to earth: 4 km
13 km/h + 4 km/h = 17 km/h The time to travel 68 km with this speed is thus t = 68 km 17 km h = 4 h

Ratio is the number of something beside another number of something i.e. ( There are 2 boys and three girls so the Ratio would be 2:3) Therefore the answer would be 5:11:4:4. Yiou want the goats ratio of the total number of animals so we will add all animals EXcEPT the goat. 5+11+4 = 20 so the ratio would be 4:20
Answer:
a=8.06
A=29.74
B=60.26
Step-by-step explanation:
This is a right angled triangle and Pythagoras theorem is to be obeyed.
To get c, we follow the Pythagoras rule that says
Hyp² = Opp² + Adj²
c= Hypotenuse
c²= a² + b²
c² = 4² + 7²
c² = 65
c = √65 = 8.06
For angle A,
the opposing side to the angle = a = 4
The adjacent side to the angle = b = 7
Following trigonometry rule.
Tan A = opp/adj
Tan A = 4/7
A = Tan–¹(4/7)
A = 29.74°
For angle B,
Opposing side = 7
Adjacent side = 4
Tan B = 7/4
B = Tan-¹(7/4)
B = 60.26°
