Answers
Answer: 36
Step-by-step explanation:
Given
The ratio of Mary's to Helen's necklaces is 25:9
Mary has 100 necklaces
Suppose Helen has x necklaces
Therefore the ratio can be written like
[tex]\Rightarrow \dfrac{25}{9}=\dfrac{100}{x}\\\\\Rightarrow x=\dfrac{100}{25}\times 9\\\\\Rightarrow x=4\times 9\\\Rightarrow x=36[/tex]
So, Helen has 36 necklaces

Answer:
10 / 26
Step-by-step explanation:
cos <Z = adjacent / hypotenuse
= YZ / XZ
= 10 / 26
Answer:
Cos of an angle by definition of its ratio is side adjacent/hypotenuse. The side adjacent to angle Z cannot be the hypotenuse, so it has to be 10. he hypotenuse is 26. Therefore, cosZ= 10/26 = 5/13

rounds are shown below. Chase's final score is double his score after the
four rounds. What is Chase's final score? Show your work
Answers
Answer:
the final score of chase is 170
Step-by-step explanation:
Given that
The chase final score would be double his score after the four rounds
So the chase final score is
= (Round 1 score + round 2 score + round 3 score + round 4 score) × 2
= (-35 + 45 + 90 - 15) × 2
= 170
Hence the final score of chase is 170

686.0 K
Answers
9514 1404 393
Answer:
C 413.3K
Step-by-step explanation:
Temperature is proportional to volume and pressure. Pressure has decreased by a factor of 2/3, and volume has increased by a factor of 400/200 = 2. So, the new temperature is ...
(310 K)(2/3)(2) = 413 1/3 K ≈ 413.3 K
You roll a cube which has the numbers 11, 12, 11, 12, 20, and 20 on it. You then spin a spinner which has 3 sections. The letters on the spinner are G, H, and J. P(20 and H)
Answers
Answer:
1 / 9
Step-by-step explanation:
Given the number cube :
(11,12,11,12,20,20)
Spinner : (G, H, J)
Probability = required outcome / Total possible outcomes
P(20) = 2 / 6 = 1/3
P(H) = 1 / 3
P(20 and H) = P(20) * P(H) = 1/3 * 1/3 = 1 /9

Word problems can be tricky no matter what level of math or science you are in.
First look at the question for words that indicate mathematical symbols.
"times" indicates multiplication
"and" indicates addition
"a number" means we have a variable, x, to solve for
Now we can go from left to right and write it in a mathematical equation
7x + 7 = 6x
Then, solve for x
7x + 7 = 6x
7 = 6x - 7x
7 = -1x
7/-1 = x
x = -7
Finally, we check our work.
7x + 7 = 6x
7(-7) + 7 = 6(-7)
-49 + 7 = -42
-42 = -42 √
The answer is x = -7

Clinton has a bag of Skittles. Inside the bag are 6 red, 4 orange, 7 yellow, 3 purple and 4 green Skittles. What is the probability of drawing a green Skittle, replacing it, and then drawing another green Skittle
Answers
The probability of drawing a green Skittle, replacing it, and then drawing another green Skittle is 1/36
How to determine the probability?The distribution of the Skittle is given as:
Red = 6
Orange = 4
Yellow = 7
Purple = 3
Green = 4
The total number of skittle is:
Total = 6 + 4 + 7 + 3 + 4
Evaluate
Total = 24
The probability of selecting a green skittle is:
P(Green) = 4/24
So, the probability of selecting 2 green skittles is:
P = 4/24 * 4/24
Evaluate
P = 1/36
Hence, the probability of drawing a green Skittle, replacing it, and then drawing another green Skittle is 1/36
