Answer:
B
Step-by-step explanation:
-5 - 1/8
6x8=48
7x8=56
Therefore it goes in 6 times with a remainder of 53-48=5
Identify and sum up the x^2 terms: Result: 3x^2
Next, ident. and sum up the x terms: Result: (1/3 + 2) = (7/3)x
Last, ident. and sum up the const. terms: Result: -2 - 6 = -8
The sum of these two functions is 3x^2 + (7/3)x - 8.
Answer:
The height of the cloud cover is 441.66 meters
Step-by-step explanation:
Distance = 560 m
The height of the cloud cover = h meters
According to the diagram, the worker stands at point R,
Let RT = x
tan 45⁰ = =
therefore, 1 = , h = x
Then tan 75⁰ = , substituting x = h, we have
3.732 =
3.732(560 - h) = h
3.732 × 560 = 3.732h + h
2089.92 = 4.732h
h = 441.66 m
Cost of each gallon of paint = x=$17
and Cost of each brush = y=$5.5
Step-by-step explanation:
Let Cost of each gallon of paint = x
and Cost of each brush = y
So, You purchase 8 gal of paint and 3 brushes for $152.50 can be written as:
you purchase 6 gal of paint and 2 brushes for $113.00 can be written as:
solving these equations to find value of x and y
Multiply eq(1) with 2 and eq(2) with 3
So, value of x=17
Putting value of x=17 into eq(1)
So, value of y= 5.5
Cost of each gallon of paint = x=$17
and Cost of each brush = y=$5.5
