What is the value of the digit 9 in the number that show kari's mass
Answers
Final answer:
The value of the number 9 representing Kari's mass depends on the digits' place in the number. If it's in the 'tens' place (as in 95), its value is 90; if it's in the 'ones' place (as in 19), its value is 9.
Explanation:
To determine the value of the number that represents Kari's mass, please provide the full number. The exact value of 9 in this number will depend on its placement. For instance, if Kari's mass is 95 kilograms, the value of 9 is 90 because it occupies the 'tens' place. However, if her mass would be 19 kilograms, the value of 9 would be 9 because it is in the 'ones' place. To know the value of digit, understanding the positions of numbers in place value is important.

Here's the equation for the area of a semicircle: A = (πr²)/2
Based on this, let's solve for this area in terms of π (pi):
A = π(10²)/2 = 100π/2 = 50π
The area of the semicircle, I believe, is 50π. Hope this helps, let me know if I messed up!
Answer: A=157
Step-by-step explanation: The area of a semi-circle can be found using the radius in the formula A=1/2r^2. We substitute the radius in the equation A=1/2*3.14*10^2
First we do the exponents following pemdas.
A=1/2*3.14*10^2
A=1/2*3.14*100
Then we multiply.
A=1/2*3.14*100
A=1.57*100
A=157
The final answer is 157.
Hope this helps!

Step-by-step explanation:
The answer to this question can be solved by setting up a proportion, or equivalent ratios (fractions). Since we know that 18 questions was equal to 72% correct on the test, we can set up a proportion to find the total number of questions:
, where 'x' represents the total number of questions (or 100%) of the questions on the test.
Cross-multiply and divide: 72x = 18(100) or 72x = 1800
Divide both sides by 72: 72x/72 = 1800/72
Solve for x: x = 25 questions

31= 6.2*y
31= 6.2y
Divide both sides by 6.2
31/6.2= 6.2y/6.2y
Y= 5
Checking the Answer: Plug in the answer for Y
31= 6.2(5)
31= 31
Answer is right if the solution work out.
31=6.2 times y
y=5 because 6.2 tines 5 equals 31
