There are 15 ice cream flavors and 3 different cone options. How many different 2 scoop cones can you make? (order doesn't matter and flavors can be repeated ie; chocolate on chocolate counts)
There are 675 different combinations.
How many combinations are there?The number of combinations is given by the product between the numbers of options.
For the first scoop, we have 15 possible options.For the second scoop, we also have 15 possible options.For the cone, we have 3 options.So the total number of different combinations is just given by:
C = 15*15*3 = 675
There are 675 different combinations.

Tom walks 3. 15 km to the park. He then walks a further 350 m to the shop. How many km has Tom walked in total?
Answer:
Step-by-step explanation:
We have to convert m to km and we have to add to find the total distance walked.
1000m = 1 km
350 m = 350 ÷ 1000 = 0.35 km
Total distance = 3.15 + 0.35
= 3.50 km

A student group determines the profit, in dollars, from a car wash using the function
f(x) =8(x-2) -20, where x represents the number of cars washed. What is the profit, in dollars, from washing 30 cars?
$?
Answer:
$ 204
Step-by-step explanation:
f(x)=8(x-2)
if i did this right then you would substitute 30 in for x------------8 (30-2) - 20
next you would multiply 8 times 30 and 8 times -2 and you would get 240-16-20
then you would subtract and get....................... 204

Find the exact two values for this problem in radians.
[tex]Cos x = 1/3[/tex]
Answer:
see below
Step-by-step explanation:
given function: [tex]Cos(x)=\frac{1}{3}[/tex]
------------------------------------------------------------------------------------------------------Cosine - (In a right triangle, the ratio of the length of the adjacent side to the length of the hypotenuse.)
---------------------------------------------------------------------------------------------------#1: Take the inverse cosine of both sides of the equation to extract [tex]x[/tex] from inside the cosine.
[tex]x=arccos\frac{1}{3}[/tex]
#2: Evaluate
[tex]x=1.23095941[/tex]
#3: The cosine function is positive in the first and fourth quadrants. To find the second solution, subtract the reference angle from [tex]2[/tex]π to find the solution in the fourth quadrant.
[tex]x=2(3.14159265)-1.23095941[/tex]
#4: Simplify the equation above.
- Multiply [tex]2[/tex] by [tex]3.14159265[/tex]
[tex]x=6.2831853-1.23095941[/tex]
- Subtract [tex]1.23095941[/tex] from [tex]6.2831853[/tex]
[tex]x=5.05222588[/tex]
#5: Find the period.
- The period of the function can be calculated using [tex]\frac{2\pi }{|b|}[/tex].
[tex]\frac{2\pi }{|b|}[/tex]
- Replace [tex]b[/tex] with [tex]1[/tex] in the formula for period.
[tex]\frac{2\pi }{|1|}[/tex]
#6: Solve the equation.
- The absolute value is the distance between a number and zero. The distance between [tex]0[/tex] and [tex]1[/tex] is [tex]1[/tex].
[tex]\frac{2\pi }{1}[/tex]
- Divide [tex]2\pi[/tex] by [tex]1.[/tex]
[tex]2\pi[/tex]
The period of the [tex]cos(x)[/tex] function is [tex]2\pi[/tex] so values will repeat every [tex]2\pi[/tex] radians in both directions.
[tex]x=1.23095941+2\pi n,5.05222588+2\pi n[/tex], for any integer [tex]n[/tex]

A pizza place is having a special. If you order a large pizza for a regular price $17, you can order any number of additional pizzas for $8.50 each. Use the recursive rule f(1)=17 and f(n)=f(n-1)+8.5 for each whole number n greater than 1.
Answer:
Step-by-step explanation:
f(1)=17
f(n)=f(n-1)+8.5
n f(n)=f(n-1)+8.5 f(n)
1 f(1)=17 17
2 f(2)=f(1)+8.5 =17+8.5=25.5 25.5
3 f(3)=f(3-1)+8.25=f(2)+8.25=25.50+8.5=34 34
4 f(4)=f(3)+8.25 =34+8.5=42.5 42.5

Find the value of xxx in the isosceles triangle shown below.
Answer:
X = 10
Step-by-step explanation:
if we say 1/2 base = a
a² = 13² - 12²
a² = 25
a = √25
a = 5
if 1/2 base = 5 then x = a × 2
hence X = 5 × 2 = 10

BRAINLEST!!! Work out 1/2 + 2/9 + 1/6
25 points! Will mark brainlest if option is avaliable
Answer: 8/9
Step-by-step explanation:
First, we can find a common denomiator.
The least common multiple of 2, 9, and 6 is 18.
Therefore, the lcd is 18.
1/2 = 1/2 * (9/9) = 9/18
2/9 = 2/9 * (2/2) = 4/18
1/6 = 1/6 * (3/3) = 3/18
Therefore, 1/2 + 2/9 + 1/6 = 9/18 + 4/18 + 3/18.
We can add the numerators together.
= 16/18
Divide the nuumerator and denominator by 2:
= 8/9

Solve the inequality b - 12 > -3
What are the solutions?
Answer:
b>9
Step-by-step explanation:
Answer:
b > 9
Step-by-step explanation:
Inequalities represent the value of a variable in relation to other numbers.
Solving the Inequality
The properties of equality state that if you add or subtract a number from both sides, the statement remains true. This means that we can isolate the variable by using the properties of equality.
To isolate the variable, add 12 to both sidesThis gives the inequality b > 9Understanding the Answer
The answer to the inequality is b > 9. This means that the variable must be greater than 9. So, values such as 10 or 100 could all be solutions. However, remember that 9 itself is not a solution. The inequality only accounts for values greater than 9, not equal to.
If the probability is 1/10 that someone in a group of people has red hair, how many people in a group of 50 will likely have a hair color other than red?
Answer:
5 people
Step-by-step explanation:
1/10 meaning for every 10 people there will be 1 person with red hair.
50 people is 10×5=50
also do it to the 1: 1×5=5
then we get a ratio of 5/50
5/50 reduced is still 1/10
A line passes through the point (8, 5) and has a slope of 3.
Answer:
[tex]\displaystyle 3x - y = 19\:or\:y = 3x - 19[/tex]
Step-by-step explanation:
Plug the information into the Slope-Intercept Formula:
[tex]\displaystyle 5 = 3[8] + b \hookrightarrow 5 = 24 + b; -19 = b \\ \\ y = 3x - 19[/tex]
Suppose you need to write this equation in standard form. You would follow these procedures:
y = 3x - 19
- 3x - 3x
__________
[tex]\displaystyle -3x + y = -19[/tex]
*Now, you can leave the standard equation like this, but UNIVERSALLY, the A-term is positive, so you must multiply the negative out as well.
[tex]\displaystyle \boxed{3x - y = 19}[/tex]
