Answer:
In this equation x is equal to h + 1
Step-by-step explanation:
To solve this, follow the order of operations for solving equations.
(6x-4h) = 10 + 4(1.5 + 0.5x) ----> Distribute the 4
(6x - 4h) = 10 - 6 + 2x ----> Simplify
6x - 4h = 4 + 2x ----> Subtract 4 from both sides
6x - 4h - 4 = 2x ----->Subtract 6x from both sides
-4h - 4 = -4x ----> Divide by -4
h + 1 = x
Answer:
let the
radius = diameter/2= 32/2= 16cm
now
perimeter of semi circle = <em><u>1</u></em><em><u>/</u></em><em><u>2</u></em><em><u>×</u></em><em><u>22</u></em><em><u>/</u></em><em><u>7</u></em><em><u>×</u></em><em><u>r</u></em>
= 1/2×22/7×16
= 25.14cm
hence perimeter of semi circle is 25 .14cm
Answer:
Step-by-step explanation:
given that a computer sends a packet of information along a channel and waits for a return signal acknowledging that the packet has been received. If no acknowledgment is received within a certain time, the packet is re-sent
Let X represent the number of times the packet is sent. Assume that the probability mass function of X is given by
p(x)={ cx for x=1,2,3,4, or 5
{ 0 otherwise
where c is a constant.
Let us write pdf as follows
x 1 2 3 4 5 Total
p c 2c 3c 4c 5c 15c
Since total probability = 1
we get
P(X=2)=2c = 
Answer:
9
Step-by-step explanation:
The time required by the ambulance is ...
time = distance/speed
time = (20 mi)/(40 mi/h) = 1/2 h = 30 minutes
The time required by the helicopter is ...
trip time = takeoff time + route time + landing time
= (3 min) + (15 mi)/(1 mi/min) +(3 min) = (3 + 15 + 3) min = 21 min
The difference in times is ...
(30 min) -(21 min) = 9 min
The helicopter takes 9 fewer minutes for the trip.
