Step-by-step explanation:

Corresponding sides of similar triangles are proportional.

FL/NL = EL/ML

(2x -5)/78 = 12/72 . . . . . . fill in given values

2x -5 = 78(12/72) = 13 . . . multiply by 78

2x = 18 . . . . add 5

What is 36kg in the ratio 7:2

babymother [125]

Answer:

28 Kg : 8 Kg

Step-by-step explanation:

Sum the parts of the ratio, 7 + 2 = 9 parts

Divide 36 Kg by 9 to find the value of one part of the ratio.

36 Kg ÷ 9 = 4 Kg ← value of 1 part of the ratio, thus

7 parts = 7 × 4 Kg = 28 Kg

2 parts = 2 × 4Kg = 8 Kg

36 Kg in the ratio 7 : 2 = 28 Kg : 8 Kg

You roll a 6-sided die. What is P(prime)? Write your answer as a percentage. Submit

Cloud [144]

You roll a 6-sided die. The probability of getting prime is 50%.

Solution:

Given, that we have rolled a 6 – sided die.

We have to find the P(prime) as percentage.

Now, It means that we have to find the probability of getting a prime number on the face.

On rolling a six sided die, the total possible outcomes are 1, 2, 3, 4, 5, 6

Number of possible outcomes = 6

We have to get a prime number on rolling a die

The prime numbers in possible outcomes are 2, 3, 5

So number of favorable outcomes = 3

$\text {Probability of an event as percentage }=\frac{\text { favourable number of outcomes }}{\text { total number of outcomes }} \times 100$

$\text {Probability of getting prime number on face of die }=\frac{3}{6} \times 100$

$\begin{array}{l}{\text { P(prime) }=\frac{1}{2} \times 100} \\\\ {\text { P(prime) }=50 \%}\end{array}$

Hence, probability of getting prime is 50%.
