Answer: The correct equation is (d). 15 + 40 = 5(3 + 8).

Step-by-step explanation: We are given to select the correct equation from the options that demonstrates the distributive property.

DISTRIBUTIVE PROPERTY: For any three real numbers a, b and c, the distributive property can be written as

(i) a(b + c) = ab + ac,

(ii) (a + b)c = ac + bc.

Out of the given for equations, only equation (d) gives the distribution of 5 over the addition of 3 and 8.

We have, according to the distributive property,

5(3 + 8) = 5 × 3 + 5 × 8 = 15 + 40.

Thus, the correct option is (d).

Find the difference (2m+3)-(7m-5)

weeeeeb [17]

Answer:

- 5m + 8

Step-by-step explanation:

Given:

(2m + 3) - (7m - 5)

If you want to find the differences between two values, it means you are to subtract

(2m + 3) - (7m - 5)

This means subtract (7m - 5) from

(2m + 3)

Step 1: Open parenthesis

(2m + 3) - (7m - 5)

= 2m + 3 - 7m + 5

Group like terms

= 2m - 7m + 3 + 5

= - 5m + 8

= 8 - 5m

Two boys and three girls are auditioning to play the piano for a school production. Two students will be chosen, one as the pian

Sergio039 [100]

The answer is 0.24

To calculate this, a multiplication rule is used. The multiplication rule calculates the probability that both of two events will occur. In this method, the probabilities of each event are multiplied. Here we have two events:

1. The probability that the pianist will be a boy,

2. The probability that the alternate will be a girl.

So, let's calculate these probabilities:

There are in total 5 children:

2 boys + 3 girls = 5 children.

1. The probability that the pianist will be a boy is 2 boys out of 5 children, which is 2/5.

2. The probability that the alternate will be a girl is 3 girls out of 5 children, which is 3/5.

The probability that the pianist will be a boy and the alternate will be a girl is:

2/5 × 3/5 = 6/25

6/25 × 4/4 = 24/100 = 0.24

Answer:

sin $\pi$ /4 * sin $\pi$ /6 = 1/2 *(cos $\pi$ /12 - cos 5 $\pi$ /12)

Step-by-step explanation:

Formula:- sinX sinY = (1/2) [ cos (X - Y) - cos (X + Y) ]

sin(π/4)sin(π/6)

= (1/2)[cos(π/4 - π/6) - cos(π/4 + π/6)]

= (1/2)[cos(3π/12 - 2π/12) - cos(3π/12 + 2π/12)]

= (1/2)[cos(π/12) - cos(5π/12)]
