The Oates family went out to
dinner. The price of the meal was
$33.95. They left a 15% tip.
What was the total cost?
Answer:
$39.04
Step-by-step explanation:
1.Approach
To solve this problem, one must first find the amount of tip that was left, then add the value to the cost of the meal. The amount of tip given can be found by dividing the percent value of the tip by (100) and then multiplying the result by the price of the meal.
2.Find the amount of tip
To find the amount of tip that was left, divide the percent value of the tip by (100). This technique converts the percent into a decimal. After doing so, multiply the result by the cost of the meal.
Tip as a percent: 15%
Tip as a decimal: 0.15
Amount of tip left:
33.95 * 0.15 = 5.0925
Round the result
~5.09
3.Find the total bill
Disincluding the tax, one now has to add the tip to the cost of the meal to find the total amount paid.
(tip) + (price)
= (5.09) + (33.95)
= (39.04)

Answer:
Median without outlier should be 40
For the bottom questions, it should go:
Decreases the mean, does not change the median, does not change the mode
It's decreasing the mean because it goes from 44.7 to 39
Median w/ and without outlier is both 40
Mode also stays the same w/ or without the outlier, which is 96

Peter is 8 years younger than Jonne. In 5 years time, Jonne will be twice as old as Peter. How old is Peter now?
Answer:
Age of Peter = 3 year
Step-by-step explanation:
Given:
Peter is 8 years younger than Jonne
Assume;
Age of Jonne = a
So,
Age of Peter = a - 8
After 5 years,
2[a - 8 + 5] = a + 5
2a - 6 = a + 5
a = 11
Age of Jonne = 11
Age of Peter = 11 - 8
Age of Peter = 3 year
Adrian and Violetta gat a soccer ball. The soccer ball is size 4.They want it to be size 5.They know the diameter is 9 inches. Find the volume of the soccer ball.
Answer:
382 inches
Step-by-step explanation:
Given that :
The size of the soccer ball that Adrian and Violetta got is = 4
The diameter of the soccer ball is = 9 inches
Therefore, the radius of the soccer ball is, r = [tex]$\frac{9}{2}$[/tex] inches
So the volume of the soccer ball is :
[tex]V = \frac{4}{3} \pi r^3[/tex]
[tex]V = \frac{4}{3} \times \frac{22}{7} \times \left(\frac{9}{2}\right)^3[/tex]
[tex]V = \frac{4}{3} \times \frac{22}{7} \times \frac{9}{2} \times \frac{9}{2} \times \frac{9}{2}[/tex]
V ≈ 382 inches

calculate 16+12-18-x+2=x-1
move the terms 12-x=x-1
collect like terms calculate -x-x=-1-12
divide both sides -2x=-13

A person invested $7,400 in an account growing at a rate allowing the money to
double every 6 years. How much money would be in the account after 4 years, to the
nearest dollar?
Using an exponential function, it is found that $11,747 will be in the account after 4 years.
What is an exponential function?An increasing exponential function is modeled by:
[tex]A(t) = A(0)(1 + r)^t[/tex]
In which:
A(0) is the initial value.r is the growth rate, as a decimal.In this problem, considering the initial investment of $7,400, and the fact that it doubles every 6 years, the equation is given by:
[tex]A(t) = 7400(2)^{\frac{t}{6}}[/tex]
Hence the amount in 4 years is given by:
[tex]A(4) = 7400(2)^{\frac{4}{6}} = 11747[/tex]

Which of the following is an equation of the circle with a center at (-1,4) and a radius of 2√5 units? plss pahelp naman
A. x²+ y²+2x-8y-3=0
B. x²+y²-2x-8y+3=0
C. x²+y²+2x+8y-3=0
D. x²+y²-2x+8y+3=0
Answer:
Option A
Step-by-step explanation:
The standard form of an equation of a circle is represented by the formula [tex](x-h)^2+(y-k)^2 = r^2[/tex]. Remember that [tex](h,k)[/tex] is the center and [tex]r^2[/tex] is the radius squared.
So, the equation of the circle must be [tex](x+1)^2 +(y-4)^2 = 20[/tex]. Complete the square to change the form of the equations listed in the options and find the one that is equal.
Let's try this with option A. Move the constants to the right side, then use the completing the square method to place the equation in standard form:
[tex]x^2 + y^2 +2x -8y -3 = 0\\x^2 + y^2 +2x-8y = 3\\x^2 + 2x +y^2-8y = 3\\(x^2 +2x+1)+(y^2-8y +16)=3+1+16\\(x+1)^2 + (y-4)^2=20[/tex]
The end result matches with the equation determined before, so option A is the answer.

Write an explicit formula for the geometric sequence below and use it to find the 9th term. 256, 64, 16, 4, . . .
im doing this problem right now---
ok so a1=256 a2=64 a3=15 a4=4... find a9
the sequence divides by 1/4 every term
an=a1*r^n-1
an=(256)*(1/4)^n-1
replace n with 9
A9=(256)*(1/4)^9-1
A9=(256)*(1/4)^8
=(256)*(1/4)
A9=64^8
1/256 or a9= 0.00390625

Answer:
R=155°
S=25°
T=155°
Step-by-step explanation:
R + 25° =180°
R = 180° - 25°
R = 155°
(2) S + 155° =180°
S = 180° - 155°
S = 25°
T = R because t is opposite of r

In a right triangle, if sin 0 = 8/17 what is cos 0 explain?
Answer:
We have sin² x + cos² x =1 for all real x.
Therefore, sin² x = 1 – cos² x = 1 – (8/17)² = 1 – 64/289 = 225/289 = (15/17)².
However, remember that if x² = a², then x can be +a or –a.
Therefore, sin x can be either –15/17 or +15/17.
Everyone but Anirban so far has forgotten the negative solution.
Step-by-step explanation:
Given that sinθ=817 and cosθ<0 , we have: cosθ=−√1−sin2θ. cosθ=−√1−(817)2. cosθ=−√1−64289.

Answer:
The equation is ;
4x - y = 13
Step-by-step explanation:
The general equation of a straight line is;
y = mx + b
where m is the slope and b is the y-intercept
from what we are given, let us write the second equation in the general form
x + 4y = 10
4y = -x + 20
y = -1/4x + 20/4
y = -1/4x + 5
mathematically, when two lines are perpendicular, the product of their slope is -1
So for the second line with slope m2
m2 * -1/4 = -1
m2 = 4
So, using the general form, we have the equation as;
y = 4x + b
To get the value of b, we substitute the coordinates of the given point (3,-1)
-1 = 4(3) + b
-1 = 12 + b
b = -1-12
b = -13
So the equation is;
y = 4x - 13 which can be rewritten as;
4x-y = 13

Sam rented a truck for one day. There was a base fee of $14.95, and there was an additional charge of 97 cents for each mile driven. Sam had to pay $265.21 when he returned the truck. For how many miles did he drive the truck?
Answer:
258 miles
Step-by-step explanation:
y = # miles truck driven
m = each mile driven
y = 14.95 + 0.97m
265.21 = 14.95 + 0.97m
250.26 = 0.97m
m = 258

The goal of the students in the club was to raise $500. They sold 43 flowerpots. By what amount did the students exceed their goal of raising $500?
Answer:
Exceeded by 145 dollars.
Step-by-step explanation:
First you multiply 15 by 43 because each pot costs 15 dollars and they sold 45.
Then you get the answer of 645 and the goal was 500 so that means you need to subtract to see how much they exceeded by.
Subtract 500 from 645 and you get the answer of 145.
So they exceeded 145 dollars.
