There are 120 students in the seventh grade. Seventy percent of these students are involved in extracurricular activites. How ma

Tanzania [10]

First, turn 70% into a decimal by dividing 70 by 100.

70% ⇒ 0.70

Multiply 120 by 0.70.

120 × 0.70 = 84

Now we know that 84 students are involved in extracurricular activities. Subtract 84 from 120 to find the amount of students who are not involved in extracurricular activities.

120 - 84 = 36

<h2>Answer:</h2>

36 seventh grade students are not involved in extracurricular activities.

swat32

Answer:

$192.4

Step-by-step explanation:

First, we'll work out what the customer had to pay before tax.

That's

$299+10-99-25\\=185$ (USD)

4% of 185 is 7.4,

So the customer paid

$185+7.4\\=192.4$ (USD)

Which of the following illustrates a phase shift?

Natasha_Volkova [10]

Answer:

A. y = -2 - cos(x-π)

Explanation:

The general form of the trig equation is:

y = A sin (Bx + C) + D

where:

A is the amplitude

$\frac{2\pi}{B}$ is the period

$\frac{-C}{B}$ is the phase shift

D is the vertical shift

Now, let's check the choices:

A. y = -2 - cos(x-π)

$\frac{-C}{B} = \frac{\pi}{1} = \pi$

Therefore, the function has a phase shift of π

B. y = 3 cos(4x)

$\frac{-C}{B} = \frac{0}{4} = 0$

Therefore, the function has no phase shift

C. y = tan(2x)

$\frac{-C}{B} = \frac{0}{2} = 0$

Therefore, the function has no phase shift

D. y = 1 + sin(x)

$\frac{-C}{B} = \frac{0}{1} = 0$

Therefore, the function has no phase shift

Based on the above, the correct answer is A

Hope this helps :)
