Answer:
34 in 40
Step-by-step explanation:
6 in 40 is the probability of winning, so
34 in 40 is the probability of not winning.
simply do 40 - 6.
This answer can also be written as
[tex] \frac{34}{40} [/tex]
or 85%
The probability of not winning a bottle cap is 34/40.
What is probability?Probability is a field in mathematics that deals with the possibility of how an event is likely to occur or true.
The probability of favorable outcomes (winning) = 6The probability of unfavorable outcomes (not winning) = 40 - 6 = 34The total possible outcome = 40The probability of not winning = 34/40

Answer:
8x - 5y - 13
Step-by-step explanation:
(6x - 3y - 12) - (2x +2y - 10)
(6x - 3y - 12) - 2x - 2y + 10
6x - 3y - 23 - 2x - 2y + 10
8x - 5y - 13
Answer:
4x+y=22
Step-by-step explanation:
6x+3y-12-(2x+2y)=10
Based on BODMAS we will have to deal with the bracket first
6x+3y-12-2x-2y=10
To continue with the solution we will have to collect like terms
That is,
6x-2x+3y-2y=10+12
4x+y=22
This can't be solved further because we don't really know the value of x and y...it can only be solved further by knowing the value of either x or y but we are not given...so we will have to leave our final answer to be
4x+y=22
Find the volume of the three-dimensional figure in terms of x.
Answer:
That is a cylinder and cylinder volume = PI * radius^2 * height
radius = x + 5
height = x
volume = PI * (x + 5)^2 * x
volume = PI * (x^2 + 10x + 25) * x
volume = PI * x^3 + 10x^2 + 25x

Michael, Trina, and Vanessa work together to mow lawns in their neighborhood. Michael mowed 8 lawns in 3 days, Trina mowed 5 lawns in 2 days, and Vanessa mowed 9 lawns in 4 days. Find the unit rate in lawns per day for each person and place the unit rates in order from least to greatest.
Final answer:
The unit rates in lawns per day for Michael, Trina, and Vanessa are 8/3, 5/2, and 9/4 respectively. The unit rates are in order from least to greatest.
Explanation:
To find the unit rate in lawns per day for each person, we will divide the number of lawns mowed by the number of days it took for each person.
For Michael, he mowed 8 lawns in 3 days, so the unit rate is 8/3 lawns per day.
For Trina, she mowed 5 lawns in 2 days, so the unit rate is 5/2 lawns per day.
For Vanessa, she mowed 9 lawns in 4 days, so the unit rate is 9/4 lawns per day.
Placing the unit rates in order from least to greatest, we have:
Trina: 5/2 lawns per day
Michael: 8/3 lawns per day
Vanessa: 9/4 lawns per day

PLEASE HELP! 30 PTS!! Explain how to find the height of this rectangular prism, given a volume of 360 in.3, a length of 24 in., and a width of 3 in.
Answer:
The height is 5 in
Step-by-step explanation:
V = l*w*h
Substitute in what we know
360 = 24 *3*h
360 = 72h
Divide each side by 72
360/72 = 72h/72
5 = h
The height is 5 in
Answer:
The height is 5 inches
Step-by-step explanation:
Knowing that he volume of a rectangular prism is V = L*W*H, it is given that V = 360, L = 24, and W = 3. Substitute these values into the equation and get 360 = 24*3*H. This can simplify to 360 = 72*H and by dividing both sides by 72, you get H = 5. This means that he height is 5 inches.

Alexandra and her children went into a grocery store and she bought $7.65 worth of
apples and bananas. Each apple costs $1.75 and each banana costs $0.40. She bought
a total of 9 apples and bananas altogether. Determine the number of apples and the
number of bananas that Alexandra bought.
Answer:
[tex]\large \boxed{\text{3 apples and 6 bananas}}[/tex]
Step-by-step explanation:
Let a = the number of apples
And b = the number of bananas. Then,
[tex]\begin{array}{rcll}(1) \, 1.75a + 0.40 b & = & 7.65&\\(2)\, \, \, \, \quad \qquad a + b & = &9&\\(3) \, 0.40a + 0.40b & = &3.60&\text{Multiplied (2) by 0.40}\\1.35a & =&4.05\\(4) \, \, \quad \qquad \qquad a & =& \mathbf{3}&\text{Divided each side by 1.35}\\3 + b & = &9& \text{Substituted(4) into (2)}\\b &=& \mathbf{6}&\text{Subtracted 3 from each side}\\\end{array}\\\text{They bought $\large \boxed{\textbf{3 apples and 6 bananas}}$}[/tex]
Check:
[tex]\begin{array}{cccl}3(1.75) + 6(0.40) = 7.65 & \qquad & 3 + 6 = 9\\5.25 + 2.40 = 7.65 & \qquad & 9 = 9\\7.65 = 7.65 & \qquad & \\\end{array}[/tex]
OK.
Alexandra bought 3 apples and 6 bananas
Number of apples = a
Number of bananas = b
From the information given, the equation to use will be:
a + b = 9 ....... i
1.75a + 0.40b = 7.65 ...... ii
From equation i, a = 9 - b ...... iii
Put equation iii into ii
1.75a + 0.40b = 7.65
1.75(9 - b) + 0.4b = 7.65
15.75 - 1.75b + 0.4b = 7.65
Collect like terms
-1.75b + 0.4b = 7.65 - 15.75
-1.35b = -8.1
b = 8.1/1.35
b = 6
She bought 6 bananas
Number of apples bought = 9 - 6 = 3 apples.
Therefore, Alexandra bought 3 apples and 6 bananas

A prism whose base is a 9-sided polygon is intersected by a plane. In which case could the cross section be a 10-sided polygon?
The cross-section will be a 10-sided polygon only when the plane makes a narrow angle with the base, i.e. it will cut one base and 8 edges of the prism, resulting in there being 10 points of intersection, leaving a 10-sided polygon as the cross-section.

The probability of drawing a yellow or green marble out of a bag containing 3 blue, 2 green , 8 yellow , 4 red , and 3 orange marbles.
Final answer:
The probability of drawing a yellow or green marble from a bag with various colored marbles is calculated by adding the individual probabilities of drawing a yellow marble and a green marble. Since there are 8 yellow and 2 green marbles out of a total of 20, the combined probability is 0.5 or 50%.
Explanation:
The question relates to the probability of drawing a yellow or green marble from a bag containing marbles of various colors. To find this probability, we must consider the total number of marbles and the number of yellow and green marbles specifically. If a bag contains 3 blue, 2 green, 8 yellow, 4 red, and 3 orange marbles, the total count of marbles is 20.
The probability of drawing a yellow marble (P(Yellow)) is the number of yellow marbles divided by the total number of marbles, which is 8/20 or 0.4. The probability of drawing a green marble (P(Green)) is the number of green marbles divided by the total number of marbles, which is 2/20 or 0.1.
The combined probability of drawing either a yellow or a green marble is found by adding the individual probabilities because these two events are mutually exclusive (they cannot both happen at the same time). So, the probability of drawing a yellow or green marble (P(Yellow or Green)) is P(Yellow) + P(Green) = 0.4 + 0.1 = 0.5.
Therefore, the probability of drawing a yellow or green marble is 0.5 or 50%.
If both the integers are negative, then their sum is _____
Answer:
they are always positive
Step-by-step explanation:
they are always positive because two negatives equal a positive.
If both the integers are negative, then their sum is always negative.
We need to find if both the integers are negative, then what is their sum.
What are integers rules?Adding integers is the process of finding the sum of two or more integers. It may result in an increase or a decrease in value, depending on whether the integers are positive or negative or a mixture. The addition of integers is an arithmetic operation performed on integers with the same sign or with different signs to find the sum.
Adding two positive integers always results in a positive value that is greater than both the integers.Adding two negative integers always results in a negative number that is smaller than the given numbers.Therefore, if both the integers are negative, then their sum is always negative.
