Mathematics
1 answer:
ZanzabumX [31]4 years ago
4 0

Answer:

Step-by-step explanation:

let ABCD be cyclic parallelogram.

Then ∠A=∠C

as it is cyclic so ∠A+∠C=180

∠C+∠C=180

2∠ C=180

∠C=90

So ∠A=90

similarly ∠B=∠D=90

so it is a rectangle.

Kendall has three jars of golf balls. One jar has a white and pink golf ball. The second jar has an orange and purple golf ball.
Mila [183]

Answer:

<h2>The total number of outcomes is 8.</h2>

Step-by-step explanation:

We know that there are different golf balls, white and pink, orange and purple, yellow and red. There are three jars with two golf balls each.

If Kendall chooses one golf ball from each jar, the total number of balls selected would be 4. Now, there are two different colors per jar, and 8 total golf balls with different colors. But, the sets can't have repetitions, and the order matters.

Having said that, the total number of possible sets is:

  • White, Orange, Yellow.
  • White, Purple, Red.
  • White, Orange Red.
  • White, Purple, Yellow.
  • Pink, Orange, Yellow.
  • Pink, Purple, Red.
  • Pink, Purple, Yellow.
  • Pink, Orange, Red.

Notice that these eight outcomes includes all possible results.

Therefore, there are 8 possible outcomes.

Miley’s music has a sale on music CDs. All music CDs are discounted 15%. Mariana’s receipt indicates that she saved $3 on her CD
Tcecarenko [31]

she saved $3, and we know the discount is 15%, so her savings is that 15%, thus we know 15% of that purchase is 3.


let's say the full price is x, and therefore the 100%, if we know 3 is the 15%, what is x?


\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 3&15\\ x&100 \end{array}\implies \cfrac{3}{x}=\cfrac{15}{100}\implies \cfrac{3\cdot 100}{15}=x\implies 20=x
