Answer:

X = 15

Step-by-step explanation:

We can tell that the two sides that show the degrees are equal because of the arc. We can set up a simple equation:

x + 45 = 60

x = 15

Answer:

x = 15°

Explanation:

The two marked angles are equal as they are vertically opposite angles.

∴ x + 45° = 60°

⇒ x = 60° - 45°

⇒ x = 15°

Answer:

$c = 11$

Step-by-step explanation:

Given

$Cars\ Sold:-: 8; 9; 12; c$

Required

What value of c makes the mean = 10

Mean is calculated as

$Mean = \frac{\sum x}{n}$

In this case;

Mean = 10 and n = 4;

So, we have:

$10 = \frac{8+ 9 + 12 + c}{4}$

$10 = \frac{29+ c}{4}$

Multiply both sides by 4

$10 * 4 = 29 + c$

$40 = 29 + c$

Solve for c

$c = 40 - 29$

$c = 11$

Which number below best represents a credit of $17.16?

PIT_PIT [208]

B. 17.16 represents a credit of $17.16; "credits" mean that you're receiving something, so it's added. A is incorrect because it shows the money being taken away and that isn't what a credit does. C and D aren't even the same amount of money in the question, so they aren't your answer either.
