a matches to B.

b matches to D.

c matches to A.

d matches to C.

The matching is as follow:

(a)------> (B)

(b)-------> (D)

(c)-------> (A)

(d)-------> (C)

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

We have the Block Diagrams in which the upper value is on the right side of Equation.

Now, first block diagram shows

m = 12+ 4 which is shown by (c)

Now, second block diagram shows

12 =  4 + m which is shown by (a)

Now, third block diagram shows

m= 4 x 12 which is shown by (d)

Now, fourth block diagram shows

12 = 4m which is shown by (b)

Answer: 25 PERCENT

Step-by-step explanation:

Answer:

25%

Step-by-step explanation:

There are 4 colors, probability of red or yellow:

P(red or yellow) = 2*1/4 = 1/2

And a cube faces 1 to 3:

P(1 to 3) = 3*1/6 = 1/2

Probability of the two events above:

1/2*1/2 = 1/4 = 25%

Answer:

y = 10

Step-by-step explanation:

Given y varies inversely as x then the equation relating them is

y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation

To find k use the condition x = 4 when y = 15 , then

15 = [tex]\frac{k}{4}[/tex] ( multiply both sides by 4 )

60 = k

y = [tex]\frac{60}{x}[/tex] ← equation of variation

When x = 6 , then

y = [tex]\frac{60}{6}[/tex] = 10

Answer:

B.x<25

Step-by-step explanation:

Let's solve your inequality step-by-step.

3(x+3)>4(x−4)

Step 1: Simplify both sides of the inequality.

3x+9>4x−16

Step 2: Subtract 4x from both sides.

3x+9−4x>4x−16−4x

−x+9>−16

Step 3: Subtract 9 from both sides.

−x+9−9>−16−9

−x>−25

Step 4: Divide both sides by -1.

−x/ −1 > −25/ −1

x<25

Answer:

x<25

The true statement would be A. The theoretical probability of landing on violet is 1/3.

Probability which is derived theoretically, irrespective of what outcome comes, is called theoretical probability.

Probability which is based on the outcomes of experiments performed is called experimental probability.

Suppose we want to find the probability of an event E.

Then, its probability is given as

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)}[/tex]

where favorable cases are those elementary events that belong to E, and total cases are the size of the sample space.

A spinner has 4 equal sections. After spinning the spinner 15 times, the results are recorded in a table.

The true statement would be A. The theoretical probability of landing on violet is 1/3.

Answer:

88cm^3

Step-by-step explanation:

The volume of a pyramid is the base times height divided by 3. First, we can find the area of the base. We have a right triangle with a base of 8 and a height of 6. The area of a triangle is the base times height divided by 2. This gives us:

8 * 6 ÷ 2 = 24cm^2

We can see that 11cm is the height as it is perpendicular to the base. We can set up an expression from the formula mentioned at the beginning:

11 * 24 ÷ 3 = 88cm^3

Answer:

Team A: 25 players

Team B: 24 players

Step-by-step explanation:

Team A:

to find the total # of players of the team we need to set up a fraction. 5 out out of an unknown number of players is equal to 1/5, so we set it up as:

[tex]\frac{5}{x} = \frac{1}{5}[/tex]

then we cross multiply to get

x*1 = 5*5

x=25 players

Team B

similarly to Team A

[tex]\frac{3}{x} = \frac{1}{8}[/tex]

cross multiply to get

x*1=3*8

x= 24 players
