Answer:

If your saying estimate this number in a decimal without calculators I think I might be able to help as illustrated below:

Step-by-step explanation:

2 5/6 shows that the whole number will be a 2. The 5/6 is a decimal below one as it is not one whole fraction. This means that we have to estimate the value of 5/6 and add that value to the number 2. 1/3 is a common fraction that is equal to about 0.33. This is because 0.33 + 0.33 + 0.33 is almost 1, which means 1/3 of one is indeed equal to 0.33.

This means we divide 0.33 by 2, because that would be equal to (1/3)/(2), or 1/6. 0.33/2 seems like it would be 16.5. 16.5 * 5, as in 5/6, would be 82.5.

I would then say that the estimate of 2 5/6 is 2.83.

Igoryamba

Answer:

19.6

Step-by-step explanation:

The ratio of brown paint to white paint is, 5:7 or $\frac{5}{7}$ so if he bought 14 gallons of white paint we need to figure out:

$\frac{5}{7} =\frac{14}{x}$

which we can as it only has one unknown:

5x=14×7

5x=98

x=19.6

So the answer is 19.6

Answer and Step-by-step explanation:

The equation would be y = 5x + 75

Now, plug in 1, 2, 6, and 12 for x (which represents the hours) and solve for y (which represents the price).

1 hour - $80

2 hours - $85

6 hours - $105

12 hours - $135

torisob [31]

Y = x
y = -2/3x + 5

x = -2/3x + 5
x + 2/3x = 5
3/3x + 2/3x = 5
5/3x = 5
x = 5 * 3/5
x = 15/5 reduces to 3

y = x
y = 3

so ur answer is (3,3)

I need help finding the reference angle theta prime

MakcuM [25]

Answer:

see the attachment for the angle plots

Step-by-step explanation:

θ = 5.2 is a 4th-quadrant angle, shown with terminal ray "a" in the attached diagram.

θ' is the positive acute angle between the terminal ray of θ and the x-axis. It is shown in standard position using terminal ray "r" in the attached diagram. Its value is the difference between 5.2 radians and 2π ≈ 6.28 radians, about 1.08318531 radians. The diagram shows it rounded to 2 decimal places: 1.08 radians.
