Answers
Answer:
254.34 miles²
Step-by-step explanation:
How do we find the area of a circle?
The area of a circle can be found using πr², where r = radius. We have the radius as 9 miles, and pi is shortened to 3.14.Solving
[tex]3.14*9^2[/tex] [tex]3.14*81[/tex][tex]254.34[/tex]Therefore, the area is 254.34 miles².
Have a lovely rest of your day/night, and good luck with your assignments! ♡
Answer:
Formula for area of a circle:
πr^2,
where pi is equal to 22/7 or 3.14
and r is the radius that is being squared
Plug in the actual values to this formula to find the area;
a = πr^2
a = 3.14 x 9^2
a = 3.14 x 81
a = 254.34, your answer is 254.34 square miles.
Using the data from the theoretical probability table, what is the probability of the spinner landing only once on yellow in two spins? 0.0625 0.5625 0.375 1
Answers
The probability of the spinner landing only once on yellow in two spins is 0.375. Then the correct option is C.
What is probability?Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.
The total sample will be
Total sample = 16 {RR, BB, YY, GG, RB, BR, RY, YR, RG, GR, BY, YB, BG, GB, YG, GY}
The probability of the spinner landing only once on yellow in two spins will be
Favorable event = 6 {YR, RY, YG, GY, YB, BY}
Then probability will be
[tex]P = \dfrac{6}{16}\\\\P = 0.375[/tex]

Sally, Emma and James have a total of 52 nerf toys. If James had 6 more, then he would have as many as both girls combined. Emma has three more toys than Sally. How many nerf toys do each of the three have.
(Please answer quickly it's due tomorrow morning)
Answers
Answer:
emma: 6 toys, sally: 13 toys, james: 23 toys
Step-by-step explanation:
if emma had x toys, sally would have (x-3) toys. and we know that if james had 6 more toys, he would have the same amount as both girls combined. so in this case in terms of x, james would have (x+x-3-6) toys, after simplification we get 2x-9 toys..
since we know that the three of them have 52 nerf toys as total, we can set up the equation:
x= number of toys emma has
2x-9+x+x-3=52
4x-12=52
x=16
emma has 16 toys, and sally has (16-3)=13 toys. finally, james has (2*16-9)=23 toys. 16+13+23=52

15% of y is 30 what equation could be used to solve
Answers
Answer:
Y= 200
Step-by-step explanation:
Just divide 30 by 0.15
Hope that helps!
Answer: y = 30/0.15
Step-by-step explanation:
First, convert 15% to a decimal by dividing by 100 to get 0.15. The word "of" in an equation means multiply, so the equation would be y*0.15 = 30. To isolate the variable you're trying to solve for, divide both sides by 0.15. The 0.15 on the left side of the equation cancels out, leaving you with a final equation of y = 30/0.15.

Aeen is drinking a beverage that has a pH of 3. 3. Marien is drinking a beverage that has a pH of 2. 7. About how many times the hydrogen ion concentration of Aeen’s drink is the hydrogen ion concentration of Marien’s drink? Round to the nearest whole number.
Answers
The number of times the hydrogen ion concentration of Aeen’s drink is the hydrogen ion concentration of Marien’s drink is 4 approx.
How to decide how many times some number is bigger?The phrase "times bigger" shows this:
If a number 'x' is 't' times bigger than 'y', then that means:
[tex]x = t \times y[/tex]
It is because 'y' had to multiply itself with 't' to get in equal level of 'x'
How to find the hydrogen ion concentration from the pH value?A solution with 'x' as its pH contains [tex]10^{-x} mol/L[/tex] of hydrogen ions.
For the considered case, we have:
pH of beverage drank by Marien = 2.7,Thus, its hydrogen ion concentration is [tex]10^{-2.7}[/tex] = x (say)
pH of beverage drank by Aeen = 3.3,Thus, its hydrogen ion concentration is [tex]10^{-3.3}[/tex] = y (say)
Then, let x is t times bigger than y, then that means:
[tex]x = t\times y\\\\t = \dfrac{x}{y} = \dfrac{10^{-2.7}}{10^{-3.3}} = 10^{-2.7 - (-3.3)} = 10^{-0.6} \approx 4[/tex]
It is because of the property [tex]a^b \times a^c = a^{b+c}[/tex]
Thus, hydrogen ion concentration of Marien's drink is approx 4 times the hydrogen ion concentration of Aeen's drink.

Answers
Answer:
1. 9
2. 25
3. No (Explanation below)
Step-by-step explanation:
1. Original PT Formula is c=√a²+b²
BUT you're looking for the leg so you now have the formula of a=√c²-b² *c being the hypotenuse
a= √ 15² - 12²
a= √ 225 - 144
a= √81
a= 9
2. 16 + 9 = 25
* you're not looking for an angle therefore you are most likely looking for the length of the side. Simply add the AD and DC together to get the answer. If you were looking for an angle it'll be 180°.
3. NO because a right angle is an angle of exactly 90°, whether it be at a corner of a square/rectangle, a triangle, or where two perpendicular lines intersect. Angle ABC is an obtuse angle as it measures more than 90°
