Answer:

0.45

Step-by-step explanation:

Since the percent to pull a ball with a 2 is 30% and the percent to pull a ball with a 4 is 15%, that means that the chance of pulling a ball with an even number is 0.45, or 45%. (0.30+0.15=0.45)

GEOMETRY:

iragen [17]

Answer:

See explanation

Step-by-step explanation:

∠POR is congruent to ∠VOE because they are vertical angles

∠PRV is congruent to ∠RVE because alternate interior angles are congruent when the lines are parallel.

VO is congruent to OR which is given

Therefore, ΔPRO is congruent to ΔEVO by the angle-side-angle theorem

So, PR is congruent to VE because corresponding parts of congruent triangles are congruent

Prove the identity cos(x-y)-cos(x+y)=2sinxsiny

tekilochka [14]

Answer:

see the procedure

Step-by-step explanation:

we know that

$cos(X - Y) = cosX cosY + sinX sinY\\cos(X + Y) = cosX cosY - sinX sinY$

$cos(X - Y)-cos(X + Y)=cosX cosY + sinX sinY-(cosX cosY - sinX sinY)$

$cos(X - Y)-cos(X + Y)=cosX cosY + sinX sinY-cosX cosY + sinX sinY$

$cos(X - Y)-cos(X + Y)=sinX sinY+ sinX sinY$

$cos(X - Y)-cos(X + Y)=2sinX sinY$ ----> is verified

The sum of a number and three more than twice that number is 27 .what is the smaller number ?

satela [25.4K]

number - N

The sum of a number and three more than twice that number is 27.

N + (2N + 3) = 27

what is the smaller number ?

N + 2N + 3 = 27

3N = 27 - 3

3N = 24

N = 8

Check

N + (2N + 3) = 27 = 8 + (2x8 + 3) = 8 + 16 + 3 = 27

How is the volume of a composite figure calculated? Describe the process for finding the volume of a composite figure.

Ivanshal [37]

Answer: Calculate the volume of each individual figure and add them.

Step-by-step explanation:

1. A composite figure is formed by two or more figures.

2. Then, to calculate the volume of the composite figure you must calculate the volume of each individual figure and then you must add all the volumes obtained.

3. For example, if a composite figure has a cylinder and a cone, the volume of the composite figure will be the sum of the volume of cylinder and the volume of the cone:

$V=V{(cylinder)}+V{(cone)}$
