Answer:
42
Step-by-step explanation:
half of 20 is 10
half of 28 is 14
so 10 pounds=14 people
if 10 pounds=14 people and theres 30 people
you add 14 3 times for each ten
hope this helps give me my piece of turkey now
10(4^2-(9)
Since 16-9 is 7
And 10 times 7 is 70
Answer:
The answer is B: (1,2)
Step-by-step explanation:
(solved using elimination method)
-2x+y=0
y=x+1
-x+y=1
-2x+y=0
x+y=-1
-x=-1
x=1
-1+y=1
y=2
(x,y)=(1,2)
Answer:
A. x > 21 2/3
Step-by-step explanation:
x is greater than 21 and two thirds
i did the math :]
We are tasked to solve the three angles given that we have the measurements of the sides such as
a = Zack to Rachel distance
b = Rachel to Maddie distance
c = Maddie to Zack distance
a =3
b =2.5
c =4
Solving the angles we need to use Law of Cosines:
cos A = 2.5² + 4² -3² /2*2.5*4
A = 48.59°
cos B=3² + 4² - 2.5² / 2*3*4
B = 38.625°
C=180 - 48.59° - 38.625°
C= 92.79°
The three angles are 48.59°,38.63° and 92.79°.
