Cheddar cheese cost 5.25$ per pound. Which equation best represents y, the total cost of x pounds of cheddar cheese? Best answer gets brainlist
Answer: y = 5.25x
Step-by-step explanation:
The cost of one pound of cheddar cheese is $5.25.
The number of cheese purchased is x.
The total cost of cheese would therefore be the cost of one pound of cheese multiplied by the number of pounds of cheese purchased:
= 5.25 * x
Full expression is therefore:
y = 5.25 * x
y = 5.25x

Lara is playing a video game where she hunts for treasure, like these gems:
A sapphire is worth 5 gold coins, and a ruby is worth 8 gold coins.
On her last hunt, Lara found 17 gems, all either rubies or sapphires, and sold them for 100 coins. How many sapphires did she find?
Answer:
12 sapphires
Step-by-step explanation:
Let's call the number of sapphires x. This means the number of rubies is the total number of gems minus x, or 17-x.
# of Sapphires: x
# of Rubies:17-x
A sapphire is worth 5 (gold coins) each, and a ruby is worth 8.
We also know the total amount of money is 100 coins, so
5*x+8*(17-x)=100
5x+136-8x=100
-3x=-36
x=12
Remember:
# of Sapphires: x
# of Rubies:17-x
...so Lara found 12 sapphires and 17-12=5 rubies.

How many combinations of 3 playing cards (from a 52-card deck) exist?
Answer:
22,100
Step-by-step explanation:
pls trust me i just took the test
The number of combination of 3 playing cards from 52 card deck is 22100.
What is Combination?A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter. In combinations, you can select the items in any order.
Here, total cards = 52
cards to be selected = 3
So, total possible combination = ⁵²C₃
= (52 X 51 X 50) / (3 X 2 X 1)
= 22100
Thus, the number of combination of 3 playing cards from 52 card deck is 22100.

Solve for x for the linear pairs.
Answer:
X = 13
Step-by-step explanation:
Since this is a linear pair, it equals to 180 degrees.
7x + 37 + 4x = 180
11x + 37 = 180
-37 -37
11x = 143
11x/11 = 143/11
x = 13

Complete the table and estimate the limit
Answer:
[tex]\lim_{x \to 0} \frac{\sqrt{x+5}-\sqrt{5} }{x} =\frac{\sqrt{5}}{10}[/tex]
Step-by-step explanation:
If x=-0.1, then f(x)=0.2247361538
If x=-0.01, then f(x)=0.2237187131
If x=-0.001, then f(x)=0.2236179792
If x=0.001, then f(x)=0.2235956185
If x=0.01, then f(x)=0.223495106
If x=0.1, then f(x)=0.2224998063
We can see that as x approaches 0, we see that f(x) gets closer to √5/10
Therefore, [tex]\lim_{x \to 0} \frac{\sqrt{x+5}-\sqrt{5} }{x} =\frac{\sqrt{5}}{10}[/tex]

The image provided below, I find very helpful when trying to solve difficult problems such as this one.
We use the same relationship, the only difference is we are given expressions and numbers for the segments
If the product of the segments in one chord equal the product of the segments in the other chord then,
x * 6 = 8 * ( x - 1 )
Or 6x = 8 ( x - 1 )
Now we solve for
Step 1 distribute the 8
8 * x = 8x
8 * -1 = -8
We now have 6x = 8x - 8
step 2 subtract 8x from each side
6x - 8x = -2x
8x - 8x cancels out
we now have -2x = -8
step 3 divide each side by -2
-2x / -2 = x
-8 / - 2 = -4
we're left with x = 4

Janessa is playing a board game with two friends. Using a single die, one friend rolled a four, and the other friend rolled a three. Janessa needs to roll a number higher than both friends in order to win the game, and she wants to calculate her probability of winning.
Is the probability of Janessa winning an independent event or dependent event? Why?
O) Her probability of winning is an independent event because it depends on the results of her friends’ rolls.
O) Her probability of winning a dependent event because it does not depend on the results of her friends’ rolls.
O) Her probability of winning is an independent event because it does not depend on the results of her friends’ rolls.
O) Her probability of winning is a dependent event because it depends on the results of her friends’ rolls.

find the value of x in the figure
Find the mean, median, and mode(s) of the data with and without the outlier.
45, 52, 17, 63, 57, 42, 54, 58
Answer:
Mean = 48.5, Median = 53, Mode = nothing, Outlier = 17
Step-by-step explanation:
Mean: Add all the numbers (388) then divide by how many numbers (8) are there. (= 48.5)
Median: Is the middle number () so you have to order them from least to greatest (17, 42, 45, 52, 54, 57, 58, 63) and then just keep marking them off left, right, left, right... until you get to the middle. But since there are two numbers (52, 54) you have to add them (106) then you divide by 2 (53).
Mode: Is the number that shows up the most. In this case none of them do.
Outlier: The number that is farthest from the other numbers (17).
The mean, median, and mode(s) of the data Without outlier Mean is 51
Median is 53 and Mode is None
To find the mean, median, and mode(s) of the data, we can start by arranging the numbers in order from smallest to largest:
17, 42, 45, 52, 54, 57, 58, 63
The mean is the sum of all the numbers divided by the total number of numbers.
If we remove the outlier (17), the data set becomes:
42, 45, 52, 54, 57, 58, 63
Mean:
Mean = (42 + 45 + 52 + 54 + 57 + 58 + 63) / 7 = 51
Median:
Median = (52 + 54) / 2 = 53
There is no mode in this set since no number appears more than once.
