The Jayden family eats at a restaurant that is having a 15% discount promotion. Their meal costs $78.40 before the discount, and they leave a 20% tip. If the tip applies to the cost of the meal before the discount, what is the total cost of the meal? Round your intermediate calculations and answer to the nearest cent.
Answer:
$ 80.22
Step-by-step explanation
Assumed 20% tip is on the discounted meal.The cost of the meal is $78.65
The cost of the meal after discount (15%)is 78.65(1−0.15)≈$ 66.85
Tip (20%) is : 66.85⋅0.2$13.37
Total cost of the meal is
66.85+13.37≈$80.22 [Ans]

What are the domain and range of the function f(x) = 2^x+1?
Answer:
Domain: (-∞, ∞)
Range: (0,∞)
Step-by-step explanation:
Exponential functions are curves which approach a horizontal asymptote usually at y=0 or the x-axis unless a value has been added to it. If it has, the curve shifts. This function has addition on the exponent but not to the whole function so it does not change the asymptote. Its y - values remain between 0 and ∞. This is the range, the set of y values.
However, the range of exponentials can change based on the leading coefficient. If it is negative the graph flips upside down and its range goes to -∞. This doesn't have it either.
The addition to 1 on the exponent shifts the function to the left but doesn't change the range.
In exponential functions, the x values are usually not affected and all are included in the function. Even though it shifts, the domain doesn't change either. Its domain is (-∞, ∞).
Domain: (-∞, ∞)
Range: (0,∞)

⁵/₈.b + ⁴/₅
Step-by-step explanation:
Simply combine like terms, so the two terms involving b;
The expression cannot be simplified further.
You could take out a common divisor, which is the multiplication of the two denominators:
¹/₄₀.(25b + 32)

A triangle has sides with lengths of 24 meters, 45 meters, and 49 meters. Is it a right triangle?
Answer:
No, it is not a right triangle.
Step-by-step explanation:
Use the Pythagorean Theorem to determine if these sides are sides of a right triangle.
[tex]a^{2}+b^{2}=c^{2}[/tex]
Plug in your length sides. Have the longest side represent your c variable.
a= 24
b= 45
c= 49
Solve for the equation.
[tex]24^{2}+45^{2}=49^{2}[/tex]
576+2025= 2401
2601=2401
These side lengths in a triangle are not a right triangle because 2601 does not equal 2401.
Write an equation of a line that is perpendicular to y = 3x + 4
Answer:
[tex]y = - \frac{1}{3} x + 2[/tex]
Step-by-step explanation:
Slope-intercept form
y= mx +c, where m is the slope and c is the y-intercept.
y= 3x +4
Since the given equation is already in the slope-intercept form, we can easily identify the slope of this line by looking at the coefficient of x.
slope= 3
The product of the slopes of perpendicular lines is -1. Let the slope of the perpendicular line be m.
m(3)= -1
Divide both sides by 3:
m= -⅓
y= -⅓x +c
Since the question does not specify the points the perpendicular line passes through, c can be any integer.
Thus, the equation of the perpendicular line could be y= -⅓x +2.
Simplify: |15 − 12|4 − ∣∣−21 + 98∣∣
Step-by-step explanation:
[tex] = \frac{ |15 - 12| }{4} - | \frac{ - 21 + 9}{8} | [/tex]
[tex] = \frac{ |3| }{4} - \frac{ | - 12| }{ |8| } [/tex]
[tex] = \frac{3}{4} - \frac{12}{8} [/tex]
[tex] = \frac{3}{4} - \frac{6}{4} [/tex]
[tex] = - \frac{3}{4} [/tex]
Option → B
The simplified value of the Expression [tex]\(\left| \frac{(15 - 12)}{4} \right| \times \left| \frac{(-21 + 9)}{8} \right|\)[/tex] in fractional form is 9/8.
To simplify the expression: [tex]\(\left| \frac{(15 - 12)}{4} \right| \times \left| \frac{(-21 + 9)}{8} \right|\)[/tex]
Step 1: Perform the calculations inside the absolute value signs:
[tex]\(\left| \frac{3}{4} \right| \times \left| \frac{-12}{8} \right|\)[/tex]
Step 2: Simplify the fractions inside the absolute value signs:
[tex]\(\left| \dfrac{3}{4} \right| \times \left| \dfrac{-3}{2} \right|\)[/tex]
Step 3: Evaluate the absolute values of the fractions:
[tex]\(\left| \dfrac{3}{4} \right| = \dfrac{3}{4}\)[/tex]
This is because the absolute value of any positive number is itself
[tex]\(\left| \dfrac{-3}{2} \right| = \dfrac{3}{2}[/tex]
and, the absolute value of a negative number is the positive version of that number.
Step 4: Multiply the absolute values:
= 3/4 x 3/2
Step 5: Multiply the fractions:
= 9/8
So, the simplified expression is 9/8.

what is the definition of unit rate
Answer:
A unit rate means a rate for one of something.
Step-by-step explanation:
We write this as a ratio with a denominator of one. For example, if you ran 70 yards in 10 seconds, you ran on average 7 yards in 1 second. Both of the ratios, 70 yards in 10 seconds and 7 yards in 1 second, are rates, but the 7 yards in 1 second is a unit rate.

Dragomir has 6 pairs of socks in a drawer. Each pair of socks is different from every
other pair in the drawer. He randomly removes 4 individual socks from the drawer,
one at a time. What is the probability that there is exactly 1 matching pair of socks
among these 4 socks?
Answer:
Step-by-step explanation:
12C4=495
10C2-5=40
40*6=240
240/495=48/79
The probability that there is exactly 1 matching pair of socks among these 4 socks is 48/79
What is Combination?A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter.
Give:
Dragomir has 6 pairs of socks in a drawer.
So, [tex]^{12}C_4[/tex]
= 12! / 8! 4!
= 12 x 11 x 10 x 9 x 8! / 8! x 4x 3x 2
=495
again,
[tex]^{10}C_2[/tex]-5
= 10! / 8! 2! - 5
=45 - 5
=40
Thus, for 6 pairs of socks
= 40*6
=240
Hence, probability that there is exactly 1 matching pair of socks among these 4 socks = 240/495=48/79.
