Estimate a 15% tip on a dinner bill of $32.47 by first rounding the bill amount to the nearest ten dollars.
Estimated tip: $
Answers
Answer:
$4.50
Step-by-step explanation:
First round to the nearest $10, as instructed. This will give us a bill amount of $30 once rounded. We do not round up as $32.47 is closer to $30 than 40$.
To get 15% of $30 we can simply multiply $30 by 0.15, which is the decimal equivalent of 15%.
This leaves us with an answer of $4.50.
the cost of a ticket to the circus is 21.00 for children and 36.00 for adults on a certain day attendance at the circus was 19,000 and the total gate revenue was 56,400 how many children and how many adults bought tickets?the number of children was______The number of adults was____
Answers
We know that
• The ticket for children costs $21.
,• The ticket for adults costs $36.
,• There were 19 people.
,• The total gate revenue is $56,400.
To solve this we have to form a system of linear equations. The first equation would be
[tex]x+y=1,900[/tex]Where x is children and y is adults, there were 19 in total.
The second equation would be
[tex]21x+36y=56,400[/tex]This equation represents the total earnings.
Let's isolate y in the first equation.
[tex]y=1,900-x[/tex]Now, we replace this expression in the second equation.
[tex]\begin{gathered} 21x+36(1,900-x)=56,400 \\ 21x+68,400-36x=56,400 \\ -15x=56,400-68,400 \\ -15x=-12,000 \\ x=\frac{-12,000}{-15} \\ x=800 \end{gathered}[/tex]There were 800 children.Then, we use this value to find y.
[tex]\begin{gathered} y=1,900-x \\ y=1,900-800 \\ y=1,100 \end{gathered}[/tex]There were 1,100 adults.Therefore, the number of children was 800, and the number of adults was 1,100.Raina wants to save money to buy a motorcycle.

Round your final answer to the nearest cent
Answers
AS per the compound interest, She need to pay $110.59 into the annuity each month for the annuity to have a total value of $5000 after 3 years.
Compound interest:
Compound interest is the interest calculated on the principal and the interest accumulated over the previous period.
It differs from simple interest, where as the interest is not added to the principal while calculating the interest during the next period.
Given,
Raina wants to save money to buy a motorcycle. She invests in an ordinary annuity that earns 7.8% interest, compounded quarterly.
Payment will made each quarter.
Here we need to find the amount she need to pay into the annuity each quarter for the annuity to have a total value $5,000 after 3 years.
Here we know that,
Total value of annuity after 3 years = $5,000
Interest rate = 7.8% = 0.078 compounded quarterly.
Number of year = 3 years
First, convert R as a percent to r as a decimal
r = R/100
r = 7.8/100
r = 0.078 per year,
Then, solve the equation for P
P = A / (1 + r/n)ⁿˣ
P = 5,000.00 / (1 + 0.078/4)(4)(3)
P = 5,000.00 / (1 + 0.0195)(12)
P = $3,965.73
We know that, 3 years = 36 months.
So for one moth she need to pay,
Monthly pay = $3,965.73/36 = $110.59

Write the standard form of the quadratic function whose graph is a parabola with the given vertex and that passes through the given point. (Let x be the independent variable and y be the dependent variable.)
Vertex:
(3, 18);

Answers
The standard form of the quadratic function is- 3y = x² - 6x + 27
Here, we are given-
Vertex coordinate = (3, 18)
Point on the graph = (5, 21)
The vertex form of a quadratic equation is given as-
y = a(x - h)² + k
Where h, k are the coordinates of the vertex.
a is the letter in general form of quadratic equation which is-
y = ax² + bx + c
Thus, here, h = 3, k = 18, x = 5 and y = 21
Substituting these values in the vertex form we get-
21 = a(0 - (3))² + 18
⇒ 21 - 18 = 9a
9a = 3
a = 3/9
a = 1/3
Thus, the standard form of the quadratic equation can be calculated as-
y = 1/3(x - (3))² + 18
3y = x² - 6x + 9 + 18
3y = x² - 6x + 27
Thus, the standard form of the quadratic function is- 3y = x² - 6x + 27

Answers
The definition of temperature is a measurement of how warm or cold an object or substance is in relation to a reference value.
Explain about the temperature?
An assessment of a material's or, more broadly, of any physical system's capacity to transport heat energy to another physical system. The average kinetic energy of a substance's molecules and its temperature are strongly connected.
The average kinetic energy of one atom or molecule is only revealed by the measurement of temperature. As a result, when we use the terms hot or cold to describe something, we are usually referring to something else.
Fahrenheit, Celsius, and Kelvin are the three scales that are most frequently used to measure temperature (K). Utilizing materials that expand or contract when heated or cooled, thermometers monitor temperature.
Since 6x36 is 216, the temperature climbed by 216 degrees.

2x +3y + x +5y +50 -2x = 180º Combine like terms
x+6y =180º
2) Now, we can set this linear system:
x +6y = 180 x-2 To eliminate x
2x -4y = -90
-2x -12y =-360
2x -4y = -90
----------------
-16y = -450
16y= 450
y = 28.12
y ≅ 28
x + 6(28)=180
x+168=180
x=12

If you roll a standard six-sided die, what is the probability that you get a 1 or 5? Give your answer as a simplified fraction.
Answers
Step 1: Theorem
[tex]\text{Probability of an event = }\frac{N\text{umber of required outcome}}{N\text{umber of sample space}}[/tex]Step 2: Given data
Sample space = { 1, 2, 3, 4, 5, 6}
Number of sample space = 6
Event space = {1, 5}
Number of event space = 2
Step 3: Substitute to find the probability that you get 1 or 5
[tex]\begin{gathered} \text{Probability that you get 1 or 5 = }\frac{2}{6} \\ =\text{ }\frac{1}{3} \end{gathered}[/tex]Answer: 1/3
There are 6 sides. Both of those numbers are two numbers, so it would be 2/6. To simplify it, divide the top and the bottom by the same number. I divided both the numerator and the denominator by 2.
then, your answer would be 1/3

[tex]undefined[/tex]What if Tanisha needs 40 bowls for the picnic? Explain how to write an equation with a letter for an unknown factor to find the num er of packs she should buy. Than find the unknown factor.
Answers
We know that each pack has 6 bowls and we need 40 bowls. Let x be the number of packs, then we can write:
[tex]6x=40[/tex]If we move the coefficient of x to the right hand side, we get
[tex]x=\frac{40}{6}[/tex]which gives x= 6.666.
However, the number of packs are integer numbers, so we must round up to the nearest integer. Hence, the answer is 7 packs.

Define fraction.A fraction is a number that is a component of a whole. By breaking a whole into a number of parts, it is evaluated. For instance, the symbol for half of a complete number or item is 12. The components of a whole or group of items are represented by fractions. A fraction consists of two components. The numerator is the figure at the top of the line. It details the number of equal portions that were taken from the total or collection. The denominator is the figure that appears below the line. A fractional equation is one in which one or more of its terms have the unknown as their denominator.
