Joey ate brunch at a restaurant. The bill came to $39. If he left a 15% tip, how much was the tip?
Answer:
The tip that Joey left was $ 5.85.
Step-by-step explanation:
Given that Joey ate brunch at a restaurant, and the bill came to $ 39, to determine, if he left a 15% tip, how much was the value of it, the following calculation should be performed:
39 x 15/100 = X
585/100 = X
5.85 = X
So, the tip that Joey left was $ 5.85.
At a snack bar, each medium drink costs $1.85 and each large drink cost c more dollars than a medium drink. If 5 medium drinks and 5 large drinks cost a total of $20.50, what is the value of c?
A) 0.45
B) 0.40
C) 0.30
D) 0.25
Answer:
B) 0.40
Step-by-step explanation:
m = 1.85
l = 1.85 + c
With 5 medium drinks and 5 large drinks:
C = 5m + 5l
20.5 = 5(1.85) + 5(1.85 + c)
20.5 = 9.25 + 9.25 + 5c
20.5 = 18.5 + 5c
5c = 20.5 - 18.5
5c = 2
c = 2/5 = 0.4

Ethan buys a bag of cookies that contains 8 chocolate chip cookies, 7 peanut butter cookies, 7 sugar
cookies, and 7 oatmeal cookies.
What is the probability that Ethan feaches in the bag and randomly selects an oatmeal cookie from the
bag, eats it, then reaches back in the bag and randomly selects a peanut butter cookie? Round your answer
to four decimal places.
Answer:
0.0603
Step-by-step explanation:
probabilty ethan picks an oatmeal and peanut butter cookie = probability of selecting an oatmeal cookie x probability of selecting a peanut butter cookie
probability of selecting an oatmeal cookie = number of oatmeal cookies / total number of cookies
probability of selecting a peanut butter cookie = number of peanut butter cookies / total number of cookies
total number of cookies = 7 + 7 + 7 + 8 = 29
probability of selecting an oatmeal cookie = 7/29
probability of selecting a peanut butter cookie = 7/28
after eating oatmeal cookies, the amount of cookies would reduce by 1
7/29 x 7/28

Answer:
B
Step-by-step explanation:
i did the math
The joint relative frequency of being a child who prefers watermelon is 132/445 option (A) Divide 132 by 445 is correct.
What is a conditional relative frequency?It is defined as the frequency that can be evaluated by the two-way frequency table. Usually, we can obtain this frequency by dividing the frequency that is not in the frequency cell by the total frequency.
To find the joint relative frequency of being a child who prefers watermelon:
Total number of children who prefers watermelon = 132
Total number of children and adults = 445
joint relative frequency of being a child who prefers watermelon:
= 132/445
Thus, the joint relative frequency of being a child who prefers watermelon is 132/445 option (A) Divide 132 by 445 is correct.

The obvious question to ask in this situation is, “how many miles does Joseph travel on Mondays”? To compute, we each distance: 3 + 6 + 6 = 15.
Joseph travels 15 miles on Mondays.
3.Perimeter means “distance around a closed figure or shape” and to compute we add each length: 3 + 6 + 6 = 15
4.Solution
Just keep adding those side lengths. 6 + 7 + 4 + 4 + 5 + 6 + 2 = 34 units
If you look closely at the shapes in the previous examples, you might notice some ways to write each perimeter as a more explicit formula. See if the results from what we have done so far match the formulas below.
find the 12th term in the sequence: 1/16, -1/8, 1/4
Answer:
Step-by-step explanation:
hello :
the sequence is geometric because : (1/4)/(-1/8) = (-1/8)/(1/16)=-2 = r
the nth term is : An =A1 × r^(n-1)
a common ratio is : r and A1 the first term
in this exercice : r =2 A1 = 1/16
when : n =12 you have the 12rd term A12
A12 = 1/16 × 2^(12-1) = 1/16 × 2^(11)

write an equation of a line passing thru the point (-4,-11) and perpendicular to the line 4x+5y= -45
Answer:
y = 5/4x - 6
Step-by-step explanation:
First, put 4x + 5y= -45 in y = mx + b form
4x + 5y= -45
5y = -4x - 45
y = -4/5x - 9
So, the slope is -4/5. Perpendicular lines have a opposite reciprocal slope, so the line's slope will be 5/4
To find the equation of the perpendicular line, plug in the slope and given point into y = mx + b, and solve for b
y = mx + b
-11 = 5/4(-4) + b
-11 = -5 + b
-6 = b
Plug in b and the slope into y = mx + b
y = 5/4x - 6
So, the equation is y = 5/4x - 6

m<BCF + m<CFE = 180° (same side interior angles are supplementary)
Substitute
4x + 11x = 180
15x = 180
Divide both sides ny 15
15x/15 = 180/15

y = 4√10
z = 12√10
Step-by-step explanation:
The geometric mean rules apply. Each of the segments labeled with a letter is the geometric mean of the segments it touches on the hypotenuse.
x = √(4×36) = 12
y = √(4×(4+36)) = 4√10
z = √(36×(36+4)) = 12√10
