Mr. Ortiz took his friends out to dinner last night and their subtotal was $88.24.
If the sales tax is 5% and if he plans to leave a 20% tip after the tax is added, how much did Mr. Ortiz spend total on dinner?
Answer:
$111.18
Step-by-step explanation:
Dinner is $88.24
Tax is (.05)$88.24 = $4.41
20% after tax added (.20)92.65 = $18.53
total dinner cost is $111.18
Nine times a number, diminished by 4, is 95
Answer:
the number is 11
Step-by-step explanation:
"Diminished" is another word for subtraction, so our equation is : 9x - 4 = 95
Add 4 on each side: 9x = 99
Divide each side by 9: x = 11
I hope this helped, please mark Brainliest, thank you!
Answer:
Step-by-step explanation:
Let a number be X
So
Nine times a number, diminished by 4, is 95
9x-4=95
9x=95+4
9x=99
X=99/9
X=11
So the number is 11

Answer:
x is also 63 degrees this is because vertical angles are congruent or like equal in measure
Step-by-step explanation:
HOPE THIS HELPEDDDD
Answer:
63 degrees
Step-by-step explanation:
Since m is parallel to n, the angle that is marked 63 degrees and x are alternate interior angles. The alternate interior angle theorem states that alternate interior angles are congruent when a line cuts through two parallel lines. So, since m and n are parallel, these are congruent angles, making x also 63 degrees.

Four of the six equations that Justin wrote are correct. Select FOUR equations that are correct.
tan (60) = 73
tan ( 30 ) =
A
B.
c.
cos ( 30") =
D.
sin ( 60 ) = ?
E. F
cos (60) =
sin ( 30 ) = 3
Answer:
ADEF
Step-by-step explanation:
Four of the six equations that Justin wrote are correct which are Trigonometric functions as sin 60° =√3/2, cos 60° = 1/2, tan 60° = √3, and cot 60° = 1 /√3.
What are Trigonometric functions?Trigonometric functions are defined as the functions which show the relationship between the angle and sides of a right-angled triangle.
Given that ΔABC
∠A = 60° and ∠B = 90° which is given in the figure
⇒ sin 60° = perpendiculer /hypotenuse
⇒ √3/2 = BC/10
⇒ BC = √3/2 × 10
⇒ BC = 5√3
⇒ tan 60° = perpendiculer /base
⇒ √3 = 5√3/AB
⇒ AB = 5√3/√3
⇒ AB = 5
⇒ sin 60° = 5√3/10 = √3/2
⇒ cos 60° = base / hypotenuse
⇒ cos 60° = 5/10 = 1/2
⇒ tan 60° = perpendiculer /base
⇒ tan 60° = 5√3/5 = √3
⇒ cot 60° = 1 /√3
Hence, four of the six equations that Justin wrote are correct which are Trigonometric functions as sin 60° =√3/2, cos 60° = 1/2, tan 60° = √3, and cot 60° = 1 /√3.

Answer:
That old mans change in height is -1 1/4 over 5 years.
Step-by-step explanation:
Answer:
-5/4 cm would be the answer.
Step-by-step explanation
This is the answer because -1/4 cm multiplied by 5 years would equal -5/4 cm.
Michael got a $50 gift card to an online music store. She uses the gift card to buy an album for $9.99. She also wants to use the gift card to buy some songs. Each song costs $1.29. Which of these inequalities describes this situation, where n is the number of songs Michael wants to buy?
Answer:
$9.99 + $1.29n ≤ $50
Step-by-step explanation:
Given that:
Worth of gift card = $50
Cost of album purchased = $9.99
Cost per song to purchase = $1.29
Number of songs to purchase = n
Inequality to model the situation :
Cost of album + cost per song * (Number of songs) ≤ worth of gift card
$9.99 + ($1.29 * n) ≤ $50
$9.99 + $1.29n ≤ $50

Avery and Nolan's baseball teams are fundraising. Avery's team has reached ⅗ of their goal. Nolan's team has reached 5/9 of their goal. Avery says her team collected more money than Nolan's team. Both of the goals are $450. Is Avery correct?
Answer:
Yes , Avery is correct
Step-by-step explanation:
To check if Avery is correct, we need to know the exact value obtained in each of their goals
For Avery’s team;
3/5 * 450 = $270
For Nolan’s team
5/9 * 450 = $250
Since $270 is greater than $250, we can see that Avery’s team collected more money

The leg of an isosceles triangle has a length 2x+4 and the base has length 3x. The
perimeter is 141, What is the length of the base?
Answer:
[tex]Base = 57[/tex]
Step-by-step explanation:
Given
[tex]Length = 2x + 4[/tex]
[tex]Base = 3x[/tex]
[tex]Perimeter = 141[/tex]
Required
Determine the length of the base
The perimeter of an isosceles triangle is:
[tex]Perimeter = 2*Length + Base[/tex]
[tex]141 = 2 (2x + 4) + 3x[/tex]
[tex]141 = 4x + 8 + 3x[/tex]
Collect Like Terms
[tex]4x + 3x = 141 - 8[/tex]
[tex]7x = 133[/tex]
Divide both sides by 7
[tex]x = 19[/tex]
To get the base, we substitute 19 for x in [tex]Base = 3x[/tex]
[tex]Base = 3 * 19[/tex]
[tex]Base = 57[/tex]

Answer:
The number 0 is the smallest non-negative integer. The natural number following 0 is 1 and no natural number precedes 0. The number 0 may or may not be considered a natural number, but it is an integer, and hence a rational number and a real number (as well as an algebraic number and a complex number).

The equations of four lines are given. Identify which lines are parallel. Line 1: y = -7x + 6 Line 2: x + (1/3)y = -6 Line 3: y = -3x - 8 Line 4: y + 7 = (-1/7)(x + 4) please help me
Answer:
Line 2 ║ Line 3
Step-by-step explanation:
y = mx + b
~~~~~~~~~~
Line 1: y = - 7x + 6
Line 2: x + (1/3)y = - 6 ⇔ y = - 3x - 18
Line 3: y = - 3x - 8
Line 4: y + 7 = (-1/7)(x + 4) ⇔ y = [tex]- \frac{1}{7}[/tex] x - [tex]\frac{43}{7}[/tex]
[tex]m_{line2}[/tex] = [tex]m_{line3}[/tex] ⇒ Line 2 ║ Line 3

The product of a number and -5 is at least 35. Write as an inequality.
Product hints at multiplication so -5n is AT LEAST meaning that it is at or greater than 35....
-5n ≥ 35
Answer:
-5x≥35
Step-by-step explanation:
The word "product" means to multiply so I know that -5 times a number x is at least 35. The phrase "at least" means greater than or equal to so I know its a ≥ sign.

Marcus and his family are planning a vacation that involves horse back riding. Horseshoe Ranch charges a $12.95 ranch entrance fee plus a $14.95 an hour to rent horses for horse back riding. Mary is going to rent a horse for 3 hours, how much will she spend?
Answer:
$57.8
Step-by-step explanation:
Horseshoe ranch charges $12.95 ranch entrance fee
$14.95 is paid per hour to rent the horse
Therefore since Mary is going to rent the horse for 3 hours then the total amount she will spend can be calculated as follows
= $12.95 + $14.95×3
= $12.95 + $44.85
=$57.8
