pls help me
Answers
Answer:
D is the right choice and no you cannot fit the pizza inside the box.
Step-by-step explanation:
D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.
Answer:
I believe the answer is D.

a big bag contains 500 beads, each of the same size, but in 5 different colors. Suppose there are 100 beads of each color and I am blindfolded. What is the fewest number of beads I must pick to be absolutely sure there are 5 beads of the same color among the beads I have picked blindfolded?
I WILL REPORT ANY FAKE OR USELESS ANSWERS
Answers
Answer:
I believe the answer is (4 * 5 +1) = 21
Step-by-step explanation:
The fewest number of beads you must pick to be absolutely sure there are 5 beads of the same color is 20 + 5 = 25 beads.
How to determine the fewest number of beads I must pick to be absolutely sure there are 5 beads of the same colorTo guarantee that you have picked 5 beads of the same color, you need to ensure that you have at least 4 beads from each of the 5 colors.
To calculate the fewest number of beads you must pick, we can consider the worst-case scenario where you have picked the maximum number of beads from each color without having 5 of the same color.
In this scenario, you would have 4 beads from each color, which totals 4 * 5 = 20 beads.
However, to guarantee that you have 5 beads of the same color, you need to pick one more bead from each color, which is an additional 5 beads.
Therefore, the fewest number of beads you must pick to be absolutely sure there are 5 beads of the same color is 20 + 5 = 25 beads.

C) x = {4, 3, 2, 1, ... }
D) x = {3, 4, 5, 6, 7, ... }
with solution pls, show the solution how did you get the answer
Answers
The best answer from the options provided is C, because "x<5" means all the numbers less than 5 and answer C only has integers that are less than 5.
Now C isn't a perfect answer, because C leaves out all the other fractions and decimals like 4.3 and 3/4 that are also less than 5, but aren't in answer C.
But given your choices, A, B, and D are not the answer, since they all have a number included that's greater than OR equal to 5.
To see why, let's break down the inequality x < 5. This inequality means that x can be any number that is less than 5, but not including 5 itself. In other words, x can be any number in the open interval (-∞, 5).
The solution set for this inequality is any set of numbers that satisfies this condition. The set of numbers in option B) {5, 6, 7, 8, 9, ... } is the only set that satisfies this condition, since all of these numbers are less than 5.
Option A) {5, 4, 3, 2, 1, ... } includes 5, which is not a solution to the inequality x < 5.
Option C) {4, 3, 2, 1, ... } does not include any numbers greater than or equal to 5, so it does not satisfy the inequality x < 5.
Option D) {3, 4, 5, 6, 7, ... } includes 5, which is not a solution to the inequality x < 5.
How many quadrants plane have a positive x-value?
Answers
Answer:
2
Step-by-step explanation:Quadrant I and Quadrant IV
Two out of the four Quadrant planes have a positive x- value.
The coordinate axis split the plane into four parts called Quadrants or which can also be called Cartesian quadrants. These divided parts of the plane are numbered I, II, III, and IV.
The first quadrant/ quadrant I which lies on the upper axis on the right side of the plane has two positive quadrants, that is one positive x and one positive y because both of them lie in the positive direction of the axis.
The second quadrant/ quadrant II which appears on the upper right side of the plane has one positive and one negative coordinate that is, one positive y and one negative x because the x coordinate lie in the opposite direction of the sign of the numbers.
In quadrant III which lies in the downward direction and the left side of the plane has two negative coordinates both x and y. both the coordinates go towards the opposite direction of the sign convention.
in the last quadrant/ quadrant IV have a positive x- coordinate and one negative y-coordinate. Because the y coordinate goes against the positive sign convention.

Step-by-step explanation:
In a stem-and-leaf plot, each leaf represents a number or piece of data.
Each the leaf will only show the last digit of the number, and the stem will have the rest.
Examples:
stem value of 1 with a leaf value of 2 = 12
a stem value of 3 with a leaf value of 0 = 30
So, this is your plot:
Stems| Leaves
1 | 2 3 5
2 | 8 8
3 | 0
4 | 2
Your data is 12, 13, 15, 28, 28, 30, 42.
Add up all these numbers and divide by the number of leaves.
Sum of data = 12 + 13 + 15 + 28 + 28 + 30 + 42 = 168
Number of leaves = 7
168 ÷ 7 = 24
The mean is the values in the stem-and-leaf plot is 24.
Andy runs and eats breakfast every morning before work. When he runs, he bums 160 calories per mile for the first 3 miles. When he runs more than 3 miles, he burns 98 calories per additional mile. On Tuesday morning. Andy runs an additional x miles over 3 miles and then consumes y calories for breakfast. Which of the following functions, f , models the net number of calories Andy has lost after running and eating breakfast on Tuesday morning? A)f(x, y) = 98x – yB)f(x, y) = 160x + 98x – y C)f(x, y) = 480 + 98x + yD)f(x, y) = 480 + 98x – y
Image of page 25
Answers
Answer:
C
Step-by-step explanation:
So you already know you do 480 calories for the first 3 miles so it doesnt need to be multiplied by the X amount of extra miles
Now you burn 98 calories per extra mile so for instance (if you did say 2 miles you would want to multiply 98 calories by 2 cause you burn 98 calories per mile)
Lastly, you just ate Y amount of calories so you need to subtract that from the burned calories cause you just now consumed Y amount of calories
So in conclusion, the answer would be C. f(x, y) = 480 + 98x + y
