Answer:

The half of the moon facing the sun is always lit, but the different phases we view from Earth happen because:

<h2>we only see parts of the lit side as the moon goes around the Earth.</h2>

Step-by-step explanation:

The moon phases occur because the Sun lights different parts of the Moon as the Moon revolves around the Earth. So, we only see the parts of the Moon that are being lit while it orbits Earth.

Answer:

$\sf adjacent = 4.5 \ ft$

Given:

opposite side: 13 ft
adjacent unknown
angle of 71°

using tan rule:

$\sf tan(x) = \dfrac{opposite}{adjacent}$

$\hookrightarrow \sf tan(71) = \dfrac{13}{adjacent}$

$\hookrightarrow \sf adjacent = \dfrac{13}{tan(71) }$

$\hookrightarrow \sf adjacent = 4.5$

Gemiola [76]

Answer:

The number of pages that Polina read was 90 and the number of pages that Marcus read was 18

Step-by-step explanation:

Let

x -----> number of pages that Polina read

y ----> number of pages that Marcus read

we know that

x+y=108 ----> equation A

x=5y -----> equation B

substitute equation B in equation A and solve for y

$5y+y=108\\6y=108\\y=18$

Find the value of x

$x=5y -----> x=5(18)=90$

therefore

The number of pages that Polina read was 90 and the number of pages that Marcus read was 18

4. Diego is thinking of two positive numbers. He says, "If we triple the first number and

aleksandr82 [10.1K]

Answer:

3x + 2y = 34. and two possible pairs of positive numbers are (x, y) = (10, 2) and (x, y) = (4, 11).

Step-by-step explanation:

Let the First positive number be x and second positive number be y.

Triple of first number = 3x

double of second number = 2y

According to question,

3x + 2y = 34

Therefore, the equation is 3x + 2y = 34

So the two possible pair of numbers Diego would be thinking of must satisfy the equation 3x + 2y = 34

Now, 3x + 2y = 34

3x = 34 - 2y

Let x = 10 and by substituting its value in above expression,

$3 \times 10 = 34 - 2y$

$30 = 34 - 2y$

$2y = 34 - 30$

$2y = 4$

$y = 2$

Therefore first pair (x, y) = (10, 2)

In the same way put x = 4 then,

3x = 34 - 2y

$3 \times 4 = 34 - 2y$

$2y = 34 - 12$

$2y = 22$

$y = 11$

Therefore first pair (x, y) = (4, 11)

Therefore, (x, y) = (4, 11) and (x, y) = (10, 2) are the two possible pairs of numbers Diego could be thinking of as these both values satisfy the equation 3x + 2y = 34.
