40 hours is 79% of what?

Mathematics

Vikentia [17]3 years ago

6 0

Step-by-step explanation:

This is what I got. I hope it's correct.

Let the unknown number be x

$79 \% \: of \: x = 40$

% = /100

$\frac{79}{100} \times x = 40 \\ \frac{79x}{100} = 40$

Cross Multiply

$79x = 100 \times 40 \\ 79x = 4000$

Divide both sides of the equation by 79

$\frac{79x}{79} = \frac{4000}{79}$

Simplify

$x = 50.6329 \\ \\ x = 50.6$

1/3ab^2 Solve for a

Julli [10]

Answer:

a = 18/b²

Step-by-step explanation:

Step 1: Write equation

1/3ab² = 6

Step 2: Solve for <em>a</em>

Multiply both sides by 3: ab² = 18
Divide both sides by b²: a = 18/b²

Can you determine any purpose why these concepts are present in the pictures?

puteri [66]

The purpose why these concepts are present in the pictures is to develop imagination power among students.

As you imagine more, your mind becomes stronger and you have greater mental control. Innovation requires a strong imagination. If you succeed in what you set out to do, the same individuals who now accuse you of daydreaming will begin to aspire to be like you. Keep your aspirations high and your imagination expanding.

Imagination is a potent brain stimulant because it forces you to think differently than most people do. Your imagination can help you come up with scenarios that most effectively handle difficulties, even though your brain might classify them as being unexpected.

Which inequality is represented by the graph?

Taya2010 [7]

Answer:

Option B

Step-by-step explanation:

Notice that the region of the inequality is bounded by a line.

The first thing to do is find the equation of this line.

Note that the line intersects the x-axis at $x = 3.5$ and intercepts the y-axis at $y = -2.5$

We know that the equation of a line has the following form:

$y = mx + b$

Where m is the slope of the line and b is the intercept with the y axis.

So we already know that:

$b = -2.5 = -\frac{5}{2}$

Then we know that when $x = 3.5$ then $y = 0$

Thus:

$0 = 3.5m -2.5$

Ahroa we clear m.

$m = \frac{2.5}{3.5}\\\\m = \frac{5}{7}$

Then, the equation of the line is:

$y = \frac{5}{7}x -\frac{5}{2}$

We can also multiply by -2 both sides of the equation and we have:

$-2y = -\frac{10}{7}x +5$

Then:

$\frac{10}{7}x -2y =5$

The option that contains this equation is option B.

To verify it, enter a point within the shaded region, such as the point (0,0), in the selected inequality. If the inequality is satisfied then option B is correct

$\frac{10}{7}x -2y\leq5\\\\\frac{10}{7}(0) -2(0)\leq5\\\\0\leq5$

The inequality is satisfied because 0 is less than 5. Then the correct option is B
