1 answer:
USPshnik [31]3 years ago
5 0

Answer:

The answers would be as follows:

3

3

1

1

Step-by-step explanation:

We can tell that the first two have an infinite number of solutions because when we try to solve, we get a true statement. The first one is done for you below.

-6x + 7 = -6x + 7 ------> Add 6x to both sides

7 = 7 (TRUE STATEMENT)

We can tell the next two have no solution due to the fact that they develop a false statement when trying to solve.

-3x + 7 = 3x + 7 ----> Subtract 7 from both sides

-3x = 3x ---> Divide by 3

-x = x (UNTRUE STATEMENT)

1. What is the value of x? Do not convert to decimal. Keep your answer in exact (radical) form. Show all of your work. This is P
lesya [120]

Answer:

The value of x is \sqrt{113}.

Step-by-step explanation:

It is given that hypotenuse is \sqrt{177}. So, the legs would be x and 8.

Let's use Pythagoras theorem,

a^{2} +b^{2} =c^{2}

Plug in the numbers to solve for x.

x^{2} +8^{2} =\sqrt{177} ^{2}

Simplify it

x^{2} +64 =177

Subtract both sides 64.

x^{2} =113

Take square root on both sides

x=\sqrt{113}

We can not simplify the radical.

So, let's keep this as answer.

Answer: Yes, they are similar- and the Scale Factor is 2.5

Step-by-step explanation: To find the scale factor, simply divide the larger number on the bigger shape by its counterpart in the smaller image, so for example: 60 divided by 24 is 2.5, and there is your scale factor. You can further test this by multiplying 4 x 2.5 which gives us 10, the other value on the larger shape.

Vco = 1/3×πr2h
Vcy = Vco --> πr^2×h = 1/3πR^2×h
h's cancel, as well as π's
r^2 = 1/3R^2 --> R^2 = 3r^2 -->
SR (R^2) = SR (3r^2)
R = SR(3)×r
