Answer:
7.722cm^2, x=129
Step-by-step explanation:
12*12=144- area of the whole square
the diameter for the circle is 12
radius is 6
Area for circle= pi* r²
3.142*6^2=113.112
144-113.112=30.888
30.888/4=7.722
Answer:
The lemonade costs 1.4.
Step-by-step explanation:
This question is solved using a system of equations.
I am going to say that:
x is the cost of a cookie.
y is the cost of a lemonade.
Total cost for cookie and lemonade is 1.80.
This means that 
.
As we want y, we have that 
Lemonade costs 1.00 more than the cookie?
This means that:
So
The lemonade costs 1.4.
Answer:
93 degrees
Step-by-step explanation:
First, you would need to observe the image and see where to start off. You can see that there is a triangle below the "?" and you would be able to get the answer if you can find the measures of the small triangle(because of vertical angles) So,
180-127= 53.
180-146=34.
Since the angles of a triangle adds up to 180 degrees, 53+34+x=180.
x=93
Now, just flip the angle around and "?" = 93 degrees.
ANSWER:
168
EXPLANATION:
27 - 13 = 14
14 is one twelfth of the number
so 14 x 12 = 168
The value of the first one is negative 13 the second 6
