Since there are more than 6 people at the table, we know that the 18% gratuity is going to be charged. In order to multiply a number by a percent, you need to first convert it to a decimal and 18% as a decimal is .18. Just the gratuity would be .18p, but, this is where they're trying to trick you. It is asking for the total cost of the meal including gratuity. The whole meal is 100%, so you add 100%to 18% and get 118%. 118% converted to a decimal is 1.18, so the total cost of the meal including gratuity can be expressed by 1.18p.
Answer: 50
Step-by-step explanation:
7/10 can of cola= 1 glass.
35 cans of Sola= y
7/10 equals 0.7 as decimal
0.7 = 1
35 = y
Cross multiply
0.7y = 35
Divide both side by 0.7
y = 35/0.7
= 50
50 glasses will be filled
You want to get the x by itself so add 3y to the other side and divide 3y+6 by 1 and you get 3y+6 and divide the 6 by 3 and your answer is 2
Answer:
Step-by-step explanation:
This arc has the same measurement as the central angle. The central angle is LON where O is the center of the circle.
Point M forms an angle that is 1/2 the central angle when M is on the circumference and opposite the 150o angle. Therefore M is the vertex of a 75 degree angle.
76x - 1 = 75 Add 1 to both sides.
76x = 76 Divide by 76
x = 1
Answer:
Step-by-step explanation:
For this case we want to find this probability:
Because they want the area to the left of the value. We need to remember that the normal standard distribution have a mean of 0 and a deviation of 1.
We can use the following excel code: =NORM.DIST(-1.55,0,1,TRUE)
And we got:
The other possibility is use the normal standard table and we got a similar result.
