Answer:
129.8 approximately
Step-by-step explanation:
So this sounds like a problem for the Law of Cosines. The largest angle is always opposite the largest side in a triangle.
So 11 is the largest side so the angle opposite to it is what we are trying to find. Let's call that angle, X.
My math is case sensitive.
X is the angle opposite to the side x.
Law of cosines formula is:
So we are looking for X.
We know x=11, a=4, and b=8 (it didn't matter if you called b=4 and a=8).
Subtract 80 on both sides:
Divide both sides by -64:
Now do the inverse of cosine of both sides or just arccos( )
[these are same thing]
Time for the calculator:
X=129.8 approximately
Answer:
y = 2/3x
Step-by-step explanation:
Slope-intercept formula: y = mx + b
m = 2/3 because the slope is 2/3.
b = 0 because the y value of the origin is 0, as the point is at (0, 0).
That makes y = 2/3x + 0, but adding zero does nothing so you take it out to get y = 2/3x.
Answer: 10y
Step-by-step explanation: All variables equal one unless assigned a specific answer. So It is basically 9y+1
9y+1=10y
Final Answer: 10y
Hope this helps! :D
Answer:
Square root of 100.
Step-by-step explanation:
Step-by-step explanation:
We can write 10 as a fraction 10/1, therefore,
100 is a rational number.
Part A : A rational no. between 5.2 and 5.5 is 5.3.
It is rational because it can be expressed in the form
p/q where p and q are integers and q is not equal to 0, which is 53/10
Part B: A rational no. between 5.2 and 5.5 is 5.29150262213
An irrational number between 5.2 and 5.5 is 5.29150262213. It is irrational because there is no pattern that repeats and it cant be written as a fraction of two whole numbers.
Answer: 1⁷/₈ pounds
Step-by-step explanation:
The weight of the whole melon is the sum of the 1¹/₈ pounds given to the neighbor and the 6/8 pounds remaining.
Convert improper to proper:
1¹/₈ = 9/8
= 9/8 + 6/8
= 15/8
= 1⁷/₈ pounds
