you have $20 to spend at the snack bar all the snacks at the snack bar cost $1.25 how much money will you have left if you buy 7
1 answer:
First, we should find the total if you were to buy these 7 snacks. We can find the total by multiplying the cost of 1 snack by 7:
So the total after you buy 7 snacks would be $8.75. You were given $20. To find how much you would have left, let's subtract the amount that you spent on the 7 snacks by the amount you originally had:
So now we know that you will have $11.25 left after you buy 7 snacks.

1. The surface that will be exposed to the rain is the lateral surface of the cylinder and the hemisphere.
2. The lateral area of the cylinder is a rectangle with height equal to the height of the cylinder and width equal to the circumference of the base of the cylinder.
3. the circumference of the base = 2
r=2**5=10
so the lateral area = 10*h=10*40=400 (

Answer:
c) 2
Step-by-step explanation:
here you can use cross multiplication. that's where you turn the fraction into an equation. ( there's videos about it, I'm not very good at explaining )
so you can turn
into
5(x + 20) = 15x
5x + 100 = 15x
subtract 5x from both sides
100 = 10x
x = 10.
the value of x/5 would be 2, since 10/5 is 2.
Answer:
Recall that probability is given as; the number of required outcome over the number of total possible outcome.
The probability that a transmitter receives the signal being sent by itself is given as .
when there are n transmitters, the probability will be given as
Step-by-step explanation:
Probability simply the likelihood of an event occurring or not occurring.
Probability therefore is given as; the number of required outcome over number of possible outcome.
In the case of the first part above we have the number of required outcome to be at least one divided by the number of possible outcome which is 3.
while in the second part we have the number o possible outcome to be n.
