Emilia and Sydney went out to dinner. The bill came to $48. They want to leave a 20% tip and
split the bill. How much do they each pay?
$9.60
$28.80
$57.60
$68.00
Answer:
Option B is correct.
Step-by-step explanation:
Total bill = $48
Tip = 20%
Amount of tip = 20% of 48
Amount = [tex]\frac{20}{100}*48[/tex]
Amount = 0.2 * 48
Amount = $9.60
Total bill with tip = 48 + 9.60 = $57.60
Dividing by 2 as they are spliting the bill.
Each pays = [tex]\frac{57.60}{2}=28.80[/tex]
Therefore,
Option B is correct.

Consider the sequence 5, 12, 19, 26, ...
Enter numbers in the boxes to represent the fourth term as an ordered pair.
Answer:
5, 12, 19, 26, 33
Step-by-step explanation:
This is an arithmetic sequence since there is a common difference between each term. In this case, adding 7 to the previous term in the sequence gives the next term. In other words, an=a1 + d(n − 1) .
Arithmetic Sequence: d=7
This is the formula of an arithmetic sequence.an=a1 + d(n-1)
Substitute in the values of
a1=5 and d=7. an=5 + (7) (n − 1)
Simplifly each term : an=5 + 7n − 7
Subtract 7 from 5.
an=7n − 2

Expand and simplify the following
6(x + 2) - 3(x + 4)
1. Which expression can be factored into the form (ax + b)(ax - b), where
a and b are rational numbers?
4n2 - 81
2n2 - 49
2n2 + 49
4n2 + 81
The expression that can be factored into the form (ax + b)(ax - b), where a and b are rational numbers, is 4n² - 81.
What are the factors?A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor.
Here,
A.
4n² - 81,
This can be factored as (2n - 9)(2n + 9), which is of the form (ax + b)(ax - b).
B.
2n² - 49,
This can be factored as (n - 7√2)(n + 7√2), but not in the form (ax + b)(ax - b).
C.
2n² + 49:
This cannot be factored into the form (ax + b)(ax - b) using rational numbers. We can factor it over the complex numbers as (n + i√49/2)(n - i√49/2), where i is the imaginary unit, but this does not satisfy the conditions of the problem.
D.
4n² + 81,
This cannot be factored into the form (ax + b)(ax - b)
Therefore, the expression that can be factored into the form (ax + b)(ax - b), where a and b are rational numbers, is 4n2 + 81.

The coordinates of the vertices for rectangle ABCD are A (2,4), B (6,10), C (9,8) and D (5,2). What
is the length of a diagonal (AC or BD) of the rectangle?
A √13
B √52
C √60
D √65
Answer:
D. [tex]\sqrt{65}[/tex]
Step-by-step explanation:
The computation of the length of a diagonal (AC or BD) of the rectangle is shown below:
As we know that
The Diagonal length of AC is
[tex]= (x_2 - x_1)^2 + (y_2 - y_1)^2\\\\= (9 -2)^2 + (8 - 4)^2\\\\= (7)^2 + (4)^2[/tex]
[tex]= \sqrt{49 + 16}\\\\= \sqrt{65}[/tex]
Therefore correct option is D.

I recently bought a sheet of postage stamps with a dragon theme. If each stamp is 7/8 inch wide and 1-1/4 inches long what's the area and perimeter of each stamp?
Answer:
[tex]1\dfrac{3}{32}\ \text{inches}^2[/tex]
[tex]4\dfrac{1}{4}\ \text{inches}[/tex]
Step-by-step explanation:
w = Width of a stamp = [tex]\dfrac{7}{8}\ \text{inch}[/tex]
l = Length of a stamp = [tex]1\dfrac{1}{4}\ \text{inch}[/tex]
Area is given by
[tex]A=lw\\\Rightarrow A=\dfrac{7}{8}\times 1\dfrac{1}{4}\\\Rightarrow A=\dfrac{7}{8}\times \dfrac{5}{4}\\\Rightarrow A=\dfrac{35}{32}\\\Rightarrow A=1\dfrac{3}{32}\ \text{inches}^2[/tex]
The area of each stamp is [tex]1\dfrac{3}{32}\ \text{inches}^2[/tex]
Perimeter is given by
[tex]P=2(l+w)\\\Rightarrow P=2(\dfrac{7}{8}+\dfrac{5}{4})\\\Rightarrow P=2\times \dfrac{17}{8}\\\Rightarrow P=\dfrac{17}{4}=4\dfrac{1}{4}\ \text{inches}[/tex]
The perimeter of each stamp is [tex]4\dfrac{1}{4}\ \text{inches}[/tex].
