Answer:
x= 7 1/2
Step-by-step explanation:
Subtract the 1/2 to get it out of the way (whatever you do on one side of the = sign you have to do to the other)
So 10- 1/2= 9 1/2
Subtract the 2 to get it out of the way
9 1/2-2=
7 1/2

What range of weights measured on an analytical balance with a precision of 0.2mg,will round to 2.0g.What is te relative percent precision of these weights
The range of weights measured on an analytical balance with a precision of 0.2mg,will round to 2.0g is 0.1900 g to 0.2100 g.
What is analytical balance?The analytical balance is the device which is used to measure the mass or weight of the object with high level of precision.
Even using the analytical balance equipment, you do not get the accurate weight. For the measurement of the 0.2 g the precision level is ±0.1 mg.
For the positive number, the value will be 0.2100 gFor the negative number, the value will be 0.1900 g.The range of weights measured on an analytical balance with a precision of 0.2mg,will round to 2.0g is 0.1900 g to 0.2100 g.

The letters in the word MATHEMATICIAN were put in a box. What is the chance of getting letter A?
Answer:
3/13
Step-by-step explanation:
There are a total of 13 letters in the word and 3 of them are A’s so 3/13 is the probability of getting an A.
The probability of getting the letter A is given by P ( A ) = 3/13
What is Probability?The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
Probability = number of desirable outcomes / total number of possible outcomes
The value of probability lies between 0 and 1
Given data ,
Let the probability of getting the letter A be P ( A )
Now , the word is given as S = { "MATHEMATICIAN " }
The number of letters in the word S = 13 letters
The number of letter A in the word = 3 A's
So , probability of getting the letter A , P ( A ) = number of letter A in the word / number of letters in the word S
On simplifying , we get
The probability of getting the letter A , P ( A ) = 3/13
Hence , the probability is 3/13

20 POINTS!!! ILL MARK BRAINLIEST! The hypotenuse of the triangle is 32, what is the radius of Circle B? Is the radius the same all around? If, both circles have the same ratio of equal radii all around, does that make them similar, what do we think about the similarity of all circles?
circle A is 1st image
circle b is 2nd image with question on it
Answer:
the radius is 4, it is the same all around, they are similar, all circles are similar
Step-by-step explanation:
you can use Pythagoras's theorem to find the radius. √33 ^2 = 32. the other lengths must be equal because they are radii. therefore they are √16 which is 4.

please help! what is the arc RU? thank you so much!
Answer: 92° or 1.6057 radians
Step-by-step explanation:
the 4 angles created by the intersecting lines SU and RT have to equal 360°
<v = 88° because of vertical angles so
88° • 2 = 176°
360° - 176° = 184°
184°/ 2 = 92°
92°+92°+88°+88° = 360°
then, that makes 92° the central angle of arc RU and the central angle degrees is always equal to the arc it subtends

Which relation is a function?
Answer:
the third (bottom left) option
Step-by-step explanation:
for every valid value of x there must be exactly one value of y.
the first option is valid only for positive x, but then for every valid x there are always 2 possible y values (a positive and a negative one).
the second option is defined for only one value of x (3), but this x has infinitely many y values.
the fourth option is a circle defined for -r <= x <= r (r being the radius). in this defined interval almost every x has 2 assigned y values (only x = -r and x = r have one y value).

Answer:
1. 72 to 56
2. 90 to 70
Step-by-step explanation:
To fill in the blanks you need to find similar ratios,
For the first one, the ratio is 72 and ___,
because 72 is in the 9's column, find out what times 9 equals 72,
9 × ? = 72
Simply divide to find the answer,
72 ÷ 9 = ?
= 8
Now that you know that 9 is being multiplied by 8, multiply 8 and 7 together,
8 × 7
= 56
Hence the answer is 56 for the first blank,
For the second one, the ratio is 90 and ___,
because 90 is in the 9's column, find out what times 9 equals 90,
9 × ? = 90
Once again simply divide to find the answer,
90 ÷ 9 = ?
= 10
Now that you know that 9 is being multiplied by 10, multiply 10 and 7 together,
7 × 10
= 70
Hence the answer is 70 for the second blank,
