\pmb{AnSwEr\::}

these ratios are not equivalent . Please consult "Explanation" for more details

\bold{ExPlAnAtIoN}\downarrow

We can write the ratios 1 : 4 and 3 : 10 as fractions :

\text{$\displaystyle\frac{1}{4} $}

and

\text{$\displaystyle\frac{3}{10} $}

Put the fractions together :

\text{$\displaystyle\frac{1}{4} \:and\:\frac{3}{10}$}

Both fractions are in their simplest form ; the numerator and denominator do not have any common factors , except 1 , and there's no point in dividing by 1.

A tennis racket at at sport city costs $180 and is discounted 15% the same model racket costs$200 at tennis world and is on sale
MaRussiya [10]
Mate, stop repeating questions, wait until your question has been answered.


15% of 180 is (180 * 0.15) = 27.

180 - 27 = $153 paid.


20% of 200 = (200 * 0.2) = 40.

200 - 40 = $160 paid.


Therefore Sport City offered the better deal.

A bag contains 8 purple marbles & 12 green marbles. You choose one marble out of the bag without looking.
MrRissso [65]

Answer:

1. P(P) = 8/20 = 0.4

2. P(G) = 12/20 = 0.6

Step-by-step explanation:

Given;

Number of green marbles G = 12

Number of purple marbles P = 8

Total T = 12+8 = 20

The probability that you choose a purple marble P(P) is;

P(P) = number of purple marbles/total number of marbles

P(P) = P/T = 8/20 = 0.4

P(P) = 0.4

The probability that you choose a Green marble P(G) is;

P(G) = number of Green marbles/total number of marbles

P(G) = G/T = 12/20 = 0.6

P(G) = 0.6

What is the length of line segment KJ?
Karolina [17]

Please consider the attached file.

We can see that triangle JKM is a right triangle, with right angle at M. Segment KM is 6 units and segment MJ is 3 units. We can also see that KJ is hypotenuse of right triangle.

We will use Pythagoras theorem to solve for KJ as:

KJ^2=KM^2+MJ^2

KJ^2=6^2+3^2

KJ^2=36+9

KJ^2=45

Now we will take positive square root on both sides:

\sqrt{KJ^2}=\sqrt{45}

KJ=\sqrt{9\cdot 5}

KJ=3\sqrt{5}

Therefore, the length of line segment KJ is 3\sqrt{5} and option D is the correct choice.
