The table is linear because the change because it had a constant slope when we solve for change in y / change in x for each of the data points given. That slope is -0.5 and it’s constant.

Three people who work full-time are to work together on a project, but their total time on the project is to be equivalent to th

uranmaximum [27]

Answer:

1/6

Step-by-step explanation:

Let x represent the proportion of time the third person spends on the project. You want ...

1/2 + 1/3 + x = 1 . . . . full-time equivalents

5/6 + x = 1 . . . . simplify

x = 1/6 . . . . . . . subtract 5/6

The third person should budget 1/6 of their time to the project.

You are trying to find the side between the right angle and the degree (This is known as the adjacent)
You are given degree 42
You also given the longest side of 19 (This is known as the hypothenuse)
Cosine: adjacent/hypothenuse
Cos42 = x/19
0.7431448255 = x/19
x = 19 * 0.7431448255
x = 14.11975168, round to tenth

Solution: x = 14.1

Using the quadratic formula to solve 11x²-4x=1 What are The values of X?

Anvisha [2.4K]

$11x^2 - 4x = 1$
$11x^{2} - 4x - 1 = 1 - 1$
$11x^{2} - 4x - 1 = 0$
$x = \frac{-(-4) \± \sqrt{(-4)^{2} - 4(11)(-1)}}{2(11)}$
$x = \frac{4 \± \sqrt{16 + 44}}{22}$
$x = \frac{4 \± \sqrt{60}}{22}$
$x = \frac{4 \± 2\sqrt{15}}{22}$
$x = \frac{2 \± \sqrt{15}}{11}$
$x = \frac{2 + \sqrt{15}}{11}\ \bold{or}\ x = \frac{2 - \sqrt{15}}{11}$

Lisa's car averageed 15 miles per gallon of gasoline. After a tune up she noticed she was getting 18 miles per gallon of gasolin

Lady_Fox [76]

Answer:

Reduction of Gasoline Consumption
Increase in Miles Per Gallon by 3.

Step-by-step explanation:

Previous Rate of Gasoline Consumption = 15 miles per gallon

Rate of Gasoline consumption after Tune Up = 18 miles per gallon

The difference in Gasoline Consumption = 18-15 =3 miles per gallon

Since the difference is positive, Lisa noticed she got 3 extra miles for every gallon of gasoline. That is, her gasoline consumption reduced.
