If 30 is half price, then what is full price?

You can set up this problem like this:

30 = x/2

30 = (1/2)x

where x is the full price.

To solve, simply multiply each half by 2:

2(30) = 2((1/2)x)

lisov135 [29]

So 55% is really 55/100
You take 100 - 55 to find how much Mr. Williams drove
100 - 55 = 45

So Mr. Williams drove 45/100 of the miles
Simplified is 9/20 of the miles

Determine e, k, and identify the type of conic for r= 12/ 7- cos theta

nlexa [21]

Answer:

The answer is (d) ⇒ e = 1/7 , k = 12 , conic ellipse

Step-by-step explanation:

∵ r = ek/(1 ± ecosФ)

∵ r = 12/(7 - cosФ) ⇒ ÷ 7 up and down

∴ r = 12/7 ÷ 1 - 1/7 (cosФ)

∴ e = 1/7

∵ 12/7 = ke ⇒ 12/7 = k(1/7)

∴ k = 12

∵ 0 < e < 1

∴ The conic is ellipse

Find the value of 3 4(16 - 9). 31 49 58

maw [93]

Answer: First option is correct.

Step-by-step explanation:

Since we have given that

$3+4(16-9)$

We first solve the brackets:

(16-9) = 7

Now, we multiply it with 4

$7\times 4=28$

Now, we add 3 to it:

$28+3=31$

Hence, the value of expression would be 31.

Therefore, First option is correct.
