Given that <span>a bag contains 26 tiles marked with the
letters A through Z.
The probability of picking a letter from the name JACK is 4 / 26
The probability of picking a letter from the name BEN is 3 / 26.
Therefore, the probability of picking a letter from
the name JACK or from the name BEN iis given by 4 / 26 + 3 / 26 = 7 / 26 </span>
Answer:
$25.
Step-by-step explanation:
Let x be the original price of shorts.
We have been given that a store is having a sale in which all items are reduced 20%. The sales tax is 5%.
The price of shorts after 20% off will be:



Since tax is added after the discount, so the price of shorts after including the tax will be:

We are told that including tax, Jennifer paid $21 for a pair of shorts. So we can set an equation as:

Now let us solve for x.






Therefore, the original price of shorts was $25.
Answer:
18 kmh
Step-by-step explanation:
Given: Speed of cyclist is 9 km/h more than skater´s speed.
Distance covered at the given time by cyclist is 45 km and by skater is 30 km.
Let´s assume the speed of skater be "x"
∴ Speed of cyclist will be 
Remember; time= 
We know the time taken by both cyclist and skater are same.
∴ we can form an equation to find the speed of skater.
Time taken by cyclist= time taken by skater
⇒ 
Multiplying both side by 
⇒ 
Using distributive property of multiplication
⇒
Subtracting both side by 30x
⇒
Dividing both side by 15
⇒
∴
Hence, speed of the skater is 18 kmh
Sin A = 56/75
A = sin^-1 (56/75) = 48.30 degrees
Answer:The answer is 63
Step-by-step explanation:
You would divide 126/2 = 63, to check, you would see if there is a 1:1: ratio between number of redheads and all other student!
