The cost of renting a bowling alley for a party is $110, plus $5 a person for food. Which equation can be used to find the total cost, C, of a party at a bowling alley for x friends?
Answers
Answer:
c=110+5x
Step-by-step explanation:
The equation that represents the total cost is C = 5x + 110.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The expense of leasing a bowling alley for a party is $110, in addition to $5 an individual for food.
Let 'C' be the total cost and 'x' be the number of friends. Then the equation is written as,
C = 5x + 110
The equation that represents the total cost is C = 5x + 110.

Answers
Answer:H+9.3 = -9.3 : H = -18.6 (pls brainless)
Step-by-step explanation:
Subtract 9.3 from both sides.
H + 9.3 - 9.3 = -9.3 - 9.3
Simplify:
H= -18.6
h=-18.6
-18.6+9.3=-9.3

The Value of a Gold coin picturing the head of the Roman Emperor Vespasian is $105. The value is increasing at a rate of 10% per year. Write an exponential growth function model in this situation. Then find the value of the coin in 11 years
Answers
Answer:
$300
Step-by-step explanation:
The formula for Exponential growth function =
y = a( 1 + r)^t
Where
a= Initial value = $105
y = New value after t years
r = Growth rate = 10% = 0.1
t = Time in years = 11 years
y = $105( 1 + 0.1)¹¹
y = $105(1.1)¹¹
y = $299.57725414
Approximately, = $300
Therefore, the value of the coin in 11 years is $300
What is this number in standard form?
(5×1,000)+(7×10)+(8×1)+(4×110)+(1×11,000)
Answers
Standard form of given expanded form of a number is 16518.
What is meant by expanded form?The expanded form of the number is the splitting of numbers based on the place value, such as ones, tens, hundreds, thousands, ten thousand, and so on. The number that is represented by the sum of each digit multiplied by its place value is called the expanded form of the number.
Given
Expanded form = (5×1,000)+(7×10)+(8×1)+(4×110)+(1×11,000)
We have to convert the expanded form into standard form
= 5000 + 70 + 8 + 440 + 11000
= 16518
Thus, standard form of given number is 16518.

Answer:
16,518
(or 1.6518 x 10⁴)
Step-by-step explanation:
Expanded form: The digits of a number are split into individual digits based on their place value. Each digit of a number can be written in multiple of 1, 10, 100, 1000, etc.
Standard form: The combination of digits written together as a single number.
The given number is not quite, but almost, written in expanded form:
(5 × 1,000) + (7 × 10) + (8 × 1) + (4 × 110) + (1 × 11,000)
For it to truly be written in expanded form, the (4 × 110) would be written as (4 × 10) + (4 × 100) and the (1 × 11,000) would be written as either (11 × 1,000) or (1 × 10,000) + (1 × 1,000).
If the number should be written in standard form as defined above, carry out the operations in the parentheses, then add them together:
[tex]\large\begin{array}{l c r}8 \times 1 & = & 8\\7 \times 10 & = & 70\\4 \times 110 & = & 440\\5 \times 1000 & = & 5000\\1 \times 11000 & = & 11000\\\cline{3-3}& & 16518\end{array}[/tex]
-----------------------------------------------------------------------------------------------------
However, in math there is another type of Standard Form (also called "Scientific notation") that is written in the form of [tex]a \times 10^n[/tex], where [tex]1\leq a < 10[/tex] and [tex]n[/tex] is any positive or negative whole number.
To convert a number into standard form, move the decimal point to the left or right until there is one digit to the left of the decimal point.
The number of times you have moved the decimal point is the power of 10 ([tex]n[/tex]).
If the decimal point has moved to the left, the power is positive.
If the decimal point has moved to the right, the power is negative.
To convert 16518 into standard form:
Move the decimal point 4 places to the left and multiply by 10 to the power of the number of places the decimal was moved (4):
⇒ 1.6518 x 10⁴
-----------------------------------------------------------------------------------------------------

At the mall in Miami, Roberto found a jacket he liked. The normal price was $120, but the jacket was on sale for 40% off. If Roberto has $50 to spend, does he have enough to buy the jacket? If not, how much more money does he need?
Answers
Answer: No, He will need $22 to add to his money to buy jacket.
Step-by-step explanation:
Normal price of jacket =$120,
New price = 40% off which means 40% Less than the Normal price
= 40/ 100 x 120
=0.4 x 120 = 48; 120 -48= $72
New Price = $72
Therefore Roberto with $50 to spend does not have enough to buy the jacket
He will need $72- $50 =$22 to add to his money to buy jacket.
Paint cost $19.95 per gallon. Nikki needs 10.25 gallons to complete a painting project. How much will Nikki spend on paint? Remember to ground the nearest penny.
Answers
Answer: it depends. If you can buy the paint by the quarter gallon (because she needs 10.25 gallons) then 19.95 x 10.25 = $ 204.49
If she cannot buy the partial paint she needs then she would have to buy 11 gallons :
19.95 x 11 = $219.45

Answers
Answer:x=7
Step-by-step explanation:
x=7
90-55=35
5x=35
x=7
First, we know that this is a right angle and it measures 90 degrees. We have to angle measurements that are given so we need to find out what x is.
So, we will subtract 55 from 90. 90-55= 35.
Now, we will have to set 5x equal to 35 and divide in both sides of the equation.
5x=35. 5 divided by 5 is 1. And 35 divided by 5 is 7 so that leaves us with x=7.

The original price of the computer is $500. The sales tax is 6%. What is the selling price of the computer?
Answers
Answer:
$530
Step-by-step explanation:
100 + 6 = 106
500/100 X 106 = 530
The selling price of the computer is $530
What is original price?"Original Price refers to the Fixed Price, Floor Price, Tunnel Price, the Premium or any other agreed upon price and established in the Confirmation."
What is sales tax?"Tax which is charged by the government on the of an item. The tax which is included in the prices is called Value Added Tax (VAT)."
We have
Original price of the computer = $500
Sales tax = 6%
Based on the given conditions
Formula for selling price with original price and sales tax
Selling price (OP with sales tax) = OP×( tax rate in decimal form+1)
Selling price (OP with sales tax) =500 × (6% + 1)
= 500 × (0.06 + 1)
= 500 × 1.06
= 530
Hence, The selling price of the computer is $530.
