Answer:
123m squared
Step-by-step explanation:
First let's get the area of the square by doing 10*10 to get 100, now let's find the area of the semicircle. We can pretend it is a full circle and then cut it in half. We do the radius which is 5 times, pi which is 3.14 to get 15.7. We then square that to get 246.49. Since we want a semicircle we cut that in half to get 123.245. We add this to 100 to get 123.245. Since we have to round, the answer is: The area of the figure is about 123 m2.
You would change 22 to a decimal which would be .22 then multiply that by 900 which would be 198. So she spent 198 dollars on the phone
The answer you would be looking for is A.12.4 feet. You can use the equation A^2+b^2=c^2 to solve for your x being length.
Making 4^2+b^2=13^2 or
16+b=169
Take 16 from both sides
B=153 then square root both sides
B^2 or x= 12.36 or 12.4 if you choose to round up as asked in the question.
I hope this helps!
Answer:
![\boxed{ \bold{ \huge{ \boxed{ \sf{k = 53}}}}}](https://tex.z-dn.net/?f=%20%5Cboxed%7B%20%5Cbold%7B%20%5Chuge%7B%20%5Cboxed%7B%20%5Csf%7Bk%20%3D%2053%7D%7D%7D%7D%7D)
Step-by-step explanation:
![\bigstar{ \sf{ \: \: \frac{3 + k}{14} = 4}}](https://tex.z-dn.net/?f=%20%5Cbigstar%7B%20%5Csf%7B%20%20%20%5C%3A%20%20%5C%3A%20%5Cfrac%7B3%20%2B%20k%7D%7B14%7D%20%3D%204%7D%7D)
: Do cross multiplication
![\hookrightarrow{ \sf{3 + k = 4 \times 14}}](https://tex.z-dn.net/?f=%20%5Chookrightarrow%7B%20%5Csf%7B3%20%2B%20k%20%3D%204%20%5Ctimes%2014%7D%7D)
: Multiply the numbers : 4 and 14
![\hookrightarrow{ \sf{3 + k = 56}}](https://tex.z-dn.net/?f=%20%5Chookrightarrow%7B%20%5Csf%7B3%20%2B%20k%20%3D%2056%7D%7D)
Move 3 to right hand side and change it's sign
![\hookrightarrow{ \sf{k = 56 - 3}}](https://tex.z-dn.net/?f=%20%5Chookrightarrow%7B%20%5Csf%7Bk%20%3D%2056%20-%203%7D%7D)
Subtract 3 from 56
![\hookrightarrow{ \sf{k = 53}}](https://tex.z-dn.net/?f=%20%5Chookrightarrow%7B%20%5Csf%7Bk%20%3D%2053%7D%7D)
The value of k is 53
Hope I helped!
