Answer:

\frac{4}{13}

Step-by-step explanation:

To calculate how many more questions Meta solved then Aliya you have to subtract. So you write the equation:

\frac{7}{13} - \frac{3}{13} = \frac{x}{y}

Then, you move the 13 in place of the y.

Next, you subtract,

7 - 3 = 4. So, 4 = x

\frac{4}{13} is your answer

A file that is 242 megabytes is being downloaded. If the download is 17.1% complete, how many megabytes have been downloaded? Ro
valkas [14]

Answer:

4.1 megabytes

Step-by-step explanation:

well we use the rule of three

242 megabytes  ------- 100%

x      megabytes  -------- 17.1%

(x megabytes)(100%)=(242 megabytes)(17.1%)

x=\frac{242*17.1}{100} \\\\x=\frac{4138.2}{100} \\\\x=4.1382\\\\x=4.1

so there have been downloaded 4.1 megabytes

ASHA 777 [7]

Answer:

x=5

Step-by-step explanation:

First combine like terms

8x-8=4x+12

Move -8 over to the other side, it becomes +8

8x=4x+20

Now subtract 4x from 8x

4x=20

Now divide

20÷4=5

x=5

Suppose that the functions r and s are defined for all real numbers x as follows.
vlada-n [284]

Step-by-step explanation:

as explained in the other question : when applying an arithmetic operation on functions, you are applying it on the functional expressions.

(r*s)(x) = (x+3)*(2x²) = 2x³ + 6x²

(r-s)(x) = (x+3) - (2x²) = -2x² + x + 3

(r+s)(-1) = (-1 + 3) + (2×(-1)²) = 2 + 2×1 = 4

2. Find the values of the six trigonometric functions for angle 0, when AC = 10 and BC = 8.
Afina-wow [57]

Answer:

53.13degrees

Step-by-step explanation:

Using the SOH CAH TOA identity'

Sin theta = opposite/hypotenuse

Given

Hypotenuse AC= 10

Opposite BC = 8

Required

theta

Substitute

Sin theta = BC/AC

Sin theta = 8/10

sin theta= 0.8

theta = arcsin0,8

theta =  53.13

Hence the requred angle is 53.13degrees
