Answer:
y = 5/9x - 37/3
Step-by-step explanation:
5x - 9y = 8
-9y = -5x + 8
y = 5/9x - 8/9
- When a line is parallel, the slope remains the same.
y = 5/9x + b
-9 = 5/9(6) + b
-9 = 10/3 + b
-37/3 = b
(1.3X10^6ft/hr)(2.8X10^3hr)
(1.3*2.8)(10^6*10^3)
Rule (a^b)(a^c)=a^(b+c)
(3.64)(10^(6+3))
3.64(10^9)
3.64X10^9 ft
Technically we only had two significant figures and the answer should be:
3.6X10^9 if we were to express our answer to the correct number of significant figures....
Answer:
P(N)=0.3
Step-by-step explanation:
Given: P(M)= 0.46, P(M and N)=0.138
Using P(M) ×P(N)= P(M and N)
⇒0.46×P(N)= 0.138
⇒P(N)= 
⇒P(N)=0.3
Answer:
Area = 1/2 base x Height
Step-by-step explanation:
Answer:
Number of T-SHIRT sold = x = 110
Number of sweatshirt = y = 40
Step-by-step explanation:
Let
Number of T-SHIRT sold = x
Number of sweatshirt = y
The number of T-shirts sold was 10 fewer than three times the number of sweatshirts sold.
x = 3y - 10
Cost of each T-SHIRT = $11
Cost of sweatshirt = $19
Total cost = $1,970
Total = x + y
1,970 = 11(3y - 10) + 19y
1970 = 33y - 110 + 19y
1970 + 110 = 33y + 19y
2080 = 52y
y = 2,080/52
y = 40
Substitute y = 40 into
x = 3y - 10
x = 3(40) - 10
x = 120 - 10
x = 110
Number of T-SHIRT sold = x = 110
Number of sweatshirt = y = 40
