Answer:
equation is 45+2.00t. the price of 350 tickets would be 700... but the total cost is 745
Answer:
The cost for each pound of chocolate chips is $2.75 and the cost for each pound of walnuts is $3.75.
Step-by-step explanation:
9x+7y=51
3x+5y=27
----------------
9x+7y=51
-3(3x+5y)=-3(27)
-------------------------
9x+7y=51
-9x-15y=-81
-------------------
-8y=-30
8y=30
y=30/8
simplify,
y=15/4
9x+7(15/4)=51
9x+105/4=51
9x=51-105/4
9x=(204-105)/4
9x=99/4
x=(99/4)/9
x=(99/4)(1/9)=99/36
simplify
x=2.75
So the cost for each pound of chocolate chips is $2.75 and the cost for each pound of walnuts is $3.75.
Step-by-step explanation:
First,
(A intersect B) = {1,2,4,5} intersect {1,3,5,7}
= {1,5}
Now,
A'n B = (A) - (A intersect B)
= {1,2,4,5} - {1,5}
= {2,4}
Answer:
a = 139.1
b = 56.2
Step-by-step explanation:
A. Reference angle = 68°
Opp = a
Hyp = 150
Therefore:
Sin 68 = opp/hyp
Sin 68 = a/150
150*sin 68 = a
a = 139.1 (nearest tenth)
B. Reference angle = 68°
Adj = b
Hyp = 150
Therefore:
Cos 68 = adj/hyp
Cos 68 = b/150
150*cos 68 = b
b = 56.2 (nearest tenth)
Answer:
x = - 5
Step-by-step explanation:
Given
f(x) = - 4x - 10 and f(x) = 10, the equate right sides, that is
- 4x - 10 = 10 ( add 10 to both sides )
- 4x = 20 ( divide both sides by - 4 )
x = - 5
