The Maxwell family goes out for dinner. The price for the
meal is $90. The sales tax on the meal is 7.25% and they
also want to leave an 18% tip. What is the total cost of the
meal?
Answer:
$113.90
Step-by-step explanation:
Find the cost of the meal with sales tax:
90 x 0.075 = 6.525
Add that to the original cost of the meal:
90 + 6.525 = 96.525
Find the cost of the tip:
96.525 x 0.18 = 17.3745
Add the tip to the meal price:
96.525 + 17.3745 = 113.8995

11. Slope of the line is 7/10.
12. Slope of the line is [tex]-\frac{1}{3}[/tex]
Step-by-step explanation:
11. Given points are:
(-6, 1) and (4, 8)
Slope of a line is given by the formula;
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m = [tex]\frac{8-1}{4-(-6)}[/tex]
m = [tex]\frac{7}{4+6}[/tex]
m = [tex]\frac{7}{10}[/tex]
Slope of the line is 7/10.
12. Given points are:
(2, -3) and (5, -4)
Slope of the equation is;
m = [tex]\frac{-4-(-3)}{5-2}[/tex]
m = [tex]\frac{-4+3}{3}[/tex]
m = [tex]\frac{-1}{3}[/tex]
Hence,
Slope of the line is [tex]-\frac{1}{3}[/tex].

The map shows the location of the houses of Dan, Joe, Lee, and Roy:
The coordinates of the community center are (5, −1). Who has a house in the same
quadrant as the community center?
1. Dan
2. Joe
3. Lee
4. Roy
Answer: Roy
Step-by-step explanation:
(5, -1) has a positive x value and negative y value. Therefore, it is in the 4 quadrant which is the bottom right corner. In this case, Roy is the only one in the 4 quadrant where the community center is.
Answer:
its in between joe and dan

Forty-five percent of households say they would feel secure if they had​ $50,000 in savings. You randomly select 8 households and ask them if they would feel secure if they had​ $50,000 in savings. Find the probability that the number that say they would feel secure is​ (a) exactly​ five, (b) more than​ five, and​ (c) at most five.
Answer:
0.172 ; 0.0884 ; 0.9115
Step-by-step explanation:
Proportion or those who feel secure, p = 0.45
Sample size, n = 8
Using the binomial distribution formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
A.) p(x = 5)
P(x =5) = 8C5 * 0.45^5 * 0.55^3
P(x = 5) = 56 * 0.0184528125 * 0.166375
P(x = 5) = 0.1719248540625
P(x = 5) = 0.172
B.) P(x > 5)
P(x > 5) = P(x = 6) + P(x = 7) + P(x = 8)
P(x > 5) = 0.0703 + 0.0164 + 0.0017
P(x > 5) = 0.0884
C.) P( ≤ 5) = P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3) + P(x = 4) + P(x = 5)
Using the binomial probability calculator to obtain a direct solution :
P( ≤ 5) = 0.9115

A laboratory technician needs to make a 36-liter batch of a 40% acid solution. How can the laboratory technician combine a batch of an acid solution that is pure acid with another that is 20% to get the desired concentration?
Answer:
9 Litre of 100% acid, 27 Litre of 20% acid solution
Step-by-step explanation:
We know that 1 = 100% while
0.2 = 20%
We assume that x is volume of 100% solution, while y is volume of 20% solution.
x + 0.2y = (36×40/100)
x+0.2y= 14.4--------eqn(1)
x+y=36-------eqn(2)
x=36-y------eqn(3)
Input eqn(2) into 1 we have
(36-y)+0.2y= 14.4
-y+0.2y=14.4-36
-0.8y= 21.6
y=21.6/0.8
y=27
Hence, 27 Litre of 20% acid is required
From eqn(3) we can find value of x
x = 36-27
9 Litre of 100% acid is required
9 Litre of 100% acid, 27 Litre of 20% acid
Hence, the laboratory technician can combine a batch of 9 Litre of 100% acid, 27 Litre of 20% acid an acid solution that is pure acid with another that is 20% to get the desired concentration

What is the next term of the geometric sequence?
108,36, 12,
Find the difference between numbers:
Divide the second number by the first number:
36/108 = 1/33
Divide the third number by the second number:
12/36 = 1/3
The difference is 1/3
Multiply the last known number by 1/3 for the next number:
12 x 1/3 = 4
The next term is 4
