The cat has gone 7 /16

rjkz [21]

There is no explanation for this problem, as it does not describe how the distance to the gate is related to the distance across the yard.

If we make the assumption that the cat is headed directly to the gate, which is the full distance across the yard, this question is asking you to subtract the fraction 7/16 from 1, where 1 represents the full distance across the yard. Of course, the result is (16/16 - 7/16) = 9/16 of the distance across the yard.

Find the solution set of the inequality

Kobotan [32]

Step-by-step explanation:

$= > x - \frac{4}{5} \leqslant \frac{1}{5}$

$= > x \leqslant \frac{1}{5} + \frac{4}{5}$

$= > x \leqslant 1$

=> Solution in the set {-2,-1,0,1,2} is {-2,-1,0,1}

Hope you've understood the solution.

Brittany uses the rowing machine and the stair machine at the gym for an exercise program. Her trainer wants her on an exercise

dangina [55]

Answer:

The equations are: $x+ y = 30$ and $x = 3y$ .

Step-by-step explanation:

We are given that Brittany uses the rowing machine and the stair machine at the gym for an exercise program.

Let the time spend by Brittany on the stair machine be represented by the variable $x$ .

and the time spend by Brittany on the rowing machine be represented by the variable $y$ .

Now, there are two conditions stated by her trainer;

The first condition states that Brittany will exercise for 30 minutes, dividing her time between the two types of machines, that is;

$x + y = 30 \text{ minutes}$

The second condition states that Brittany will spend three times as much time on the stair machine as on the rowing machine, that is;

$x = 3y$

So, the equations are: $x+ y = 30$ and $x = 3y$ .

These equations can be solved either using the substitution method or the elimination method.

Calculate the radian measure of a 30 degree angle. Use any method you like, including sketching in the circle diagram provided.

dalvyx [7]

Answer:

The radian measure of 30° is $\frac{\pi}{6}$ radians.

Step-by-step explanation:

A complete revolution equals 360°, that is, 2π radians. If the given angle is 30°, then the value of the radian measure is calculated by the following simple rule of three:

$x = \frac{30^{\circ}}{360^{\circ}}\times 2\pi$

$x = \frac{\pi}{6}\,rad$

The radian measure of 30° is $\frac{\pi}{6}$ radians.
