A, how many different possible combinations can she spin. B what is the probability of spinning Chloe's preference vanilla ice cream with chocolate a rainbow sprinkles,
The probability of spinning vanilla ice cream with chocolate a rainbow sprinkles is 1/12
The missing part of the questionFlavor of ice cream: Vanilla, Strawberry, Chocolate
Topping: Rainbow sprinkles, Caramel sauce, Nuts, Cherries
The number of different combinationsUsing the dataset above, we have:
Ice cream = 3
Topping = 4
The number of different combinations is calculated as:
Combination = ice cream * Topping
Evaluate
Combination = 3 * 4
Combination = 12
Hence, the number of different combinations is 12
The probability of spinning vanilla ice cream with chocolate a rainbow sprinklesThe vanilla ice cream with chocolate a rainbow sprinkles is just one of the 12 combinations.
So, the probability is:
P = 1/12
Hence, the probability of spinning vanilla ice cream with chocolate a rainbow sprinkles is 1/12

Which of the following could be the equation of a line perpendicular to the line 2x−5y=7?
The equation of a line perpendicular to the line 2x − 5y = 7 is y = (-5/2)x + b
What is an equation?An equation is an expression that shows the relationship between two or more variables or numbers.
Two lines are said to be perpendicular if the product of their slopes is equal to -1.
The slope of the line:
2x - 5y = 7
5y = 2x - 7
y = (2/5)x - 7
The slope of the line 2x - 5y = 7 is 2/5. The slope of the line perpendicular is -5/2

Combine the radicals 4√7+3√28.
Answer:
10√7
Step-by-step explanation:
[tex]4 \sqrt{7} + 3 \times 2 \sqrt{7} \\ 4 \sqrt{7} + 6 \sqrt{7} \\ 10 \sqrt{7} [/tex]
Answer:
10√7
Step-by-step explanation:
To combine the radicals, you must have the same number under both radicands. Luckily, you can simplify one of the radicands. This is done by separating the radicand (√28) into its common factors (√4 x √7) and taking the square root of one of the factors (√4 = 2).
4√7 + 3√28 <---- Original expression
4√7 + 3(√4 x √7) <---- Expand √28
4√7 + (3 x 2)√7 <----- Take √4
4√7 + 6√7 <---- Multiply coefficients
10√7 <---- Add both terms

how to find the volume of a room
multiply the height x the length x the width to find the volume of a room (or another 3d object)
Evaluate the following limit:
[tex]\displaystyle \lim_{x \to \infty}{\frac{(x^2 + 1)^2 - 3x^2 + 3}{x^3 - 5}}[/tex]
If we evaluate the function at infinity, we can immediately see that:
[tex]\large\displaystyle\text{$\begin{gathered}\sf \bf{\displaystyle L = \lim_{x \to \infty}{\frac{(x^2 + 1)^2 - 3x^2 + 3}{x^3 - 5}} = \frac{\infty}{\infty}} \end{gathered}$}[/tex]
Therefore, we must perform an algebraic manipulation in order to get rid of the indeterminacy.
We can solve this limit in two ways.
Way 1:By comparison of infinities:
We first expand the binomial squared, so we get
[tex]\large\displaystyle\text{$\begin{gathered}\sf \displaystyle L = \lim_{x \to \infty}{\frac{x^4 - x^2 + 4}{x^3 - 5}} = \infty \end{gathered}$}[/tex]
Note that in the numerator we get x⁴ while in the denominator we get x³ as the highest degree terms. Therefore, the degree of the numerator is greater and the limit will be \infty. Recall that when the degree of the numerator is greater, then the limit is \infty if the terms of greater degree have the same sign.
Way 2Dividing numerator and denominator by the term of highest degree:
[tex]\large\displaystyle\text{$\begin{gathered}\sf L = \lim_{x \to \infty}\frac{x^{4}-x^{2} +4 }{x^{3}-5 } \end{gathered}$}\\[/tex]
[tex]\ \ = \lim_{x \to \infty\frac{\frac{x^{4} }{x^{4} }-\frac{x^{2} }{x^{4}}+\frac{4}{x^{4} } }{\frac{x^{3} }{x^{4}}-\frac{5}{x^{4}} } }[/tex]
[tex]\large\displaystyle\text{$\begin{gathered}\sf \bf{=\lim_{x \to \infty}\frac{1-\frac{1}{x^{2} } +\frac{4}{x^{4} } }{\frac{1}{x}-\frac{5}{x^{4} } } \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ =\frac{1}{0}=\infty } \end{gathered}$}[/tex]
Note that, in general, 1/0 is an indeterminate form. However, we are computing a limit when x →∞, and both the numerator and denominator are positive as x grows, so we can conclude that the limit will be ∞.
A line passes through the points (-3,-4) and (6,2)
What is the x intercept of this line?
Answer: x - int : (3,0)
Step-by-step explanation:
point-slope form: y - y1 = m(x - x1)
m = y2-y1/x2-x1
= -4-2/-3-6
=-6/-9
= 2/3
y1 = 2
x1 =6
y - 2 = 2/3(x-6)

0-2 = 2/3(x-6)
-2 = 2/3x - 4

You have a spinner with red and blue regions. When you spin, it comes up blue 60 percent of the time. You do an experiment where you spin the spinner 180 times, and it comes up blue 114 times. (a) What proportion of spins came up blue in your sample
Explanation:
Divide the number of times blue came up (114) over the number of spins total (180). Ignore the 60% given to you. That's a theoretical value that doesn't play any part in determining an experimental probability.
114/180 = 0.633 approximately

a, a² + 1 and a + 6 are all in arithmetic progression, in which there is a fixed difference d between consecutive terms. This mean we have
a² + 1 = a + d
a + 6 = a² + 1 + d
Eliminate d and solve for a :
(a² + 1) - (a + 6) = (a + d) - (a² + 1 + d)
a² - a - 5 = -a² + a - 1
2a² - 2a - 4 = 0

The table below shows the different combinations of honey and oats that can be used in making granola
Answer:
10:4
Step-by-step explanation:
it can be simplified
We can actually deduce here that the honey to oats ratio that doesn't follow the pattern in the table is: 10:4.
What is ratio?Ratio actually refers to the way that two or more numbers are compared in relation to their size to each other. It shows how much of one number is found in another.
From the honey to oats ratio, we can see that the pattern goes thus:
5 - 2 = 3 (this should be the number of cups of oat for the next role of ratio).This is because 10 - 3 = 7
Then 15 - 7 = 8
Therefore, the ratio that doesn't follow the pattern is 10:4.

I start a walk at 2.47pm. The walk takes 85 minutes. What time does the walk finish?
Answer:
4:12pm
Step-by-step explanation:
85 minutes = 1 hour and 25 minutes
2:47pm + 1 hour 25 minutes = 3:72 pm
72 minutes = 1 hour 12 minutes so add another 1 hour to 3 and the balance is 12 minutes so walk ends at 4:12pm
Another way to look at it is as follows:
After 13 minutes, the time is 2:47 + 0:13 = 3pm
Remaining time left is 85-13 = 72 minutes = 1 hour: 12 minutes. Add that to 3pm and you get 4:12pm
For what values of x and y is quadrilateral ABCD a parallelogram?
Answer:
x = 6 y = 4Step-by-step explanation:
AB = DC
AD = BC
we use AB and DC
6x - 26 = 8x - 38
-26 + 38 = 8x - 6x
12 = 2x
x = 12 : 2
x = 6
---------------
check
6 * 6 - 26 = 8 * 6 - 38
36 - 26 = 48 - 38
10 = 10
the answer is good
now we use AD and BC
6y + 12 = 3x + 24
-3x + 6y - 12 = 0
3y - 12 = 0
3y = 12
y = 12 : 3
y = 4
----------------------
check
6 * 4 + 12 = 3 * 6 + 24
24 + 12 = 12 + 24
36 = 36
the answer is good

find the smallest number of terms of the AP "-54,-52.5,-51,-49.5" ....that must be taken for the sum of the terms to be positive
The smallest number of terms of the AP that will make the sum of terms positive is 73.
Since we need to know the number for the sum of terms, we find the sum of terms of the AP
Sum of terms of an APThe sum of terms of an AP is given by S = n/2[2a + (n - 1)d] where
n = number of terms, a = first term and d = common differenceSince we have the AP "-54,-52.5,-51,-49.5" ....", the first term, a = -54 and the second term, a₂ = -52.5.
The common difference, d = a₂ - a
= -52.5 - (-54)
= -52.5 + 54
= 1.5
Number of terms for the Sum of terms to be positive
Since we require the sum of terms , S to be positive for a given number of terms, n.
So, S ≥ 0
n/2[2a + (n - 1)d] ≥ 0
So, substituting the values of the variables into the equation, we have
n/2[2(-54) + (n - 1) × 1.5] ≥ 0
n/2[-108 + 1.5n - 1.5] ≥ 0
n/2[1.5n - 109.5] ≥ 0
n[1.5n - 109.5] ≥ 0
So, n ≥ 0 or 1.5n - 109.5 ≥ 0
n ≥ 0 or 1.5n ≥ 109.5
n ≥ 0 or n ≥ 109.5/1.5
n ≥ 0 or n ≥ 73
Since n > 0, the minimum value of n is 73.
So, the smallest number of terms of the AP that will make the sum of terms positive is 73.

A. g(x) = x +5
B. g(x) = x+ 51
C. g(x) = 1x1-5

Suppose you drive an average of 15,000 miles per year, and your car gets 24 miles per gallon. Suppose gasoline costs $3.20 a gallon. a. How much money do you spend each year on gasoline? b. You plan to trade in your car for one that gets x more miles per gallon. Write an expression to represent the new yearly cost of gasoline. c. Write an expression to represent your total savings on gasoline per year. d. Suppose you can save $600 a year with the new car. How many miles per gallon does the new car get?
Answer:
a) $2000
b) 15000(3.20)/(24+x) = new gasoline cost (replace with variable of your choice)
c) 2000-(15000(3.20)/(24+x)) = money saved (replace with variable)
