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

the Earth moves to different positions around the Sun

we only see parts of the lit side as the moon goes around the Earth

only part of the light gets reflected to Earth

the spinning of the moon lets us see different amounts of light

x = -5

Answer:

.53

Step-by-step explanation:

your diameter is .82,so divide it by two to get your radius

.82 / 2 = .41

A = [tex]\pi[/tex] r ^2

A = [tex]\pi[/tex] .41 ^2

A = .53

Answer:

0.53

It is true.

Step-by-step explanation:

congruent polygons have the exact same size and are a perfect match because all corresponding parts are congruent (equal). ... This means that if two polygons are similar, then their corresponding angles are congruent

Answer:

D

Step-by-step explanation:

you need to divide by 2. And you need to simplify a fraction.

I believe the answer is D: 6×9÷3.

The question is a word problem, and they are asking you to put it into a numerical problem, meaning with numbers. 6 times 9 divided by 3 put into a numerical equation is 6×9÷3.

If this is incorrect, please, don't refrain to tell me. Thank you.

Answer:

B

The only diagram representing a function is B.

All the others fail rhe vertical line test. Each of the x values should have one y value assigned.

Step-by-step explanation:

Let the number of cookies be x and the number of cupcakes be y.

If the total is 280, then

[tex]5x + 2y = 280[/tex]

Subtract 5x from both sides

[tex]5x - 5x + 2y = 280 - 5x[/tex]

[tex]2y = 280 - 5x[/tex]

Make y the subject

[tex]y = 140 - \frac{5}{2}x[/tex]

See attachment for graph

Any of the following equation can be plotted on the graph (they literally represent the same thing)

[tex]5x + 2y = 280[/tex]

[tex]2y = 280 - 5x[/tex]

[tex]y = 140 - \frac{5}{2}x[/tex]

Answer:

its 200 cookies and 80 cupcakes

Answer:

25

Step-by-step explanation:

For these types of problems you'll need the Pythagorean theorem (woohoo..). This amazing formula looks like: a^2 + b^2 = c^2. The a and b in this formula are the legs of the triangle, the straight non-diagonal lines. The c stands for the hypotenuse which is the diagonal line.

Since you have both of the legs we can go ahead and plug that into our equation: 15^2 + 20^2 = c^2.

NOTE: It doesn't matter which leg you plug into which variable! Just make sure it's not c!

With exponents, it just means to multiply the number by itself. 15^2 is the same as 15(15). So, simplifying the equation, we get: 225 + 400 = c^2.

This part is pretty straightforward. I mean, unless you don't remember addition... Adding it together, you will get 625 = c^2.

This part kinda requires a calculator if you don't know all of your square roots. Luckily, this is a perfect root and goes into 25.

And that, my friend, is your answer. Hope this helped :)

Answer:

35/6

Step-by-step explanation:

Turn to 2 1/3 improper fraction

6+1=7/3

Dividing is multiplying by the reciprocal

7/3*5/2

7*5/3*2

35/6

Answer:

(1/3)πr2h.

Step-by-step explanation:

Volume of a cone:

V = (1/3)πr2h

Slant height of a cone:

s = √(r2 + h2)

Lateral surface area of a cone:

L = πrs = πr√(r2 + h2)

Base surface area of a cone (a circle):

B = πr2

Total surface area of a cone:

A = L + B = πrs + πr2 = πr(s + r) = πr(r + √(r2 + h2))

Answer:

Step-by-step explanation:

The "key" to this is to recognize that the two lines have to be the same length, they put the drawing on it's side to make it harder to see that. :/  But another way to see this is that it's an isosceles triangle and you know the two legs that they are asking us about have to be the same length,  knowing that.. we can set the two expression equal to each other

3x - 10 = 2x

now solve for x

3x - 10 -2x = 2x - 2x  ( subtracting 2x from both sides )

3x - 2x - 10 = 0

x - 10 = 0

x - 10 + 10 = 0 + 10

x = 10    ( yay)

Answer: The 4th term is 11.

Step-by-step explanation:

The given sequence: [tex]C(n) = -7 + 6(n - 1)[/tex] which represents the nth term.

To find 4th term.

Put n=4, we get

[tex]C(4) = -7 + 6(4 - 1)\\\\\Rightarrow\ C(4) = -7 + 6(3)\\\\\Rightarrow\ C(4) =-7+18\\\\\Rightarrow\ C(4) =11[/tex]

Hence, the 4th term is 11.
