Answer:

37,500 meters long

Step-by-step explanation:

The tape plays at 0.048 meters per second. First, let's find the number of seconds in 30 minutes.

30 minutes
60 seconds * 30
1800 seconds

The tape plays at 0.048 meters per second for 1800 seconds

The equation is:

0.048x = 1800
x = 1800/ 0.048
x = 37,500

The tape is $\boxed{\text{37,500 meters long}}$

WILL MARK BRAINLISET!!!!!!!!!! Three-fifths of the members of the Spanish club are girls. There are a total of 30 girls in the S

Aneli [31]

Answer:

The three options that can be used are A, C and E.

Step-by-step explanation:

Let's review the information given to us to answer the question correctly:

Total of girls in the Spanish club = 30

Total of girls in the Spanish club = 3/5 of the members

Which statements can be used to solve for x, the total number of members in the Spanish club?

Let's solve for x, this way:

3/5 * x = 30

3x = 30 * 5

3x = 150

x = 150/3

x = 50

Now, let's evaluate the three options that can be used to solve for x:

A. Three-fifths x = 30 . This option can be used.

B. Three-fifths = x/30 . This option can't be used.

C. Three-fifths (Five-thirds) x = 30 (five-thirds) . This option can be used.

D. (Three-fifths (five-thirds) x = 30 (five-thirds) . This option can't be used.

E. x = 50. This option can be used.

The three options that can be used are A, C and E.

PilotLPTM [1.2K]

A square's diagonal has a length equal to √(2) times the length of its sides. So if the side length is x, then the diagonal is such that

√(2) x = 10 cm

→ x = 10/√(2) cm ≈ 7.07 cm

The perimeter of a square is 4 times its side length, so the perimeter is

4 (10/√(2) cm) = 40/√(2) cm ≈ 28.3 cm

which makes 28.4 cm the closest answer.

Is 3x+4y=7 linear or nonlinear

Sloan [31]

Linear. It's in the form C= ax + by, so you back solve to get into the form you know is linear (y= mx + b). So using SADMEP (opposite of Pemdas) we can decide which order to solve for "Y=" in. 4y =7-3x. Y=((7-3X)/4). Y= 7/4 -3/4x. Y=-3/4x +7/4. Which is linear

The graph represents two complex numbers, z1 and z2, as solid line vectors. Which points represent their complex conjugates?

REY [17]

Point A represents the complex conjugate z₁ and point L represents the complex conjugate of z₂ respectively

The complex conjugate of a complex number is a complex number that having equal magnitude in the real and imaginary part as the complex number to which it is a conjugate, but the imaginary part of the complex conjugate has an opposite sign to the original complex number

Therefore, graphically, the complex conjugate is a reflection of the original complex number across the x-axis because the transformation for a reflection of the point (x, y) across the x-axis is given as follows;

Preimage (x, y) reflected across the x axis give the image (x, -y)

Where in a complex number, we have;

x = The real part

y = The imaginary part

The reflection of z₁ across the x-axis gives the point A, while the reflection of z₂ across the x-axis gives the point L

Therefore;

Point A represents the complex conjugate z₁ and point L represents the complex conjugate of z₂
