ANSWER
8 minutes
EXPLANATION
We know that the cost of using the internet in dollars is given by,
Where x is the number of minutes spent on the internet.
In this problem, we have to find how many minutes will 6 dollars buy. In other words, we have to find x for y = 6. To solve the given equation for x, we have to multiply both sides by 4,
And divide both sides by 3,
So, for y = 6, x is,
Hence, $6 will buy 8 minutes.
Answer:
x=8
Step-by-step explanation:
Cause 8+1 =9
Answer:
8/17
Step-by-step explanation:
The correct and complete question is:
<em>Use △XYZ, in which ∠X is a right angle and tanY=8/15. What is the ratio for sinY?</em>
From definition:
tan(Y) = opposite/adjacent
From the graph and the question:
tan(Y) = XZ/XY = 8/15
Then:
XZ = 8 and XY = 15. Using pytaghorean theorem:
XZ² + XY² = YZ²
8² + 15² = YZ²
√289 = YZ
17 = YZ
From definition:
sin(Y) = opposite/hypotenuse
From the graph:
sin(Y) = XZ/YZ
sin(Y)= 8/17
Answer:
17. y=36 degrees
18. p=98
19. n= 380
20. m= 1036
Step-by-step explanation:
Answer:
x=19.3333
Step-by-step explanation:
Cross multiply
6(x-3)=14*7
6x-18=98
6x=98+18
6x=116
x=19.3333
