Answer:

Total cost of Mark's board is $3.75.

Step-by-step explanation:

We are given the following in the question:

Length of wooden board =

=7\dfrac{1}{2}\text{ foot}

Unit cost of board = $0.50 per foot

Total cost of board =

=\text{Length of board}\times \text{Unit cost of board}\\\\=7\dfrac{1}{2}\times 0.50\\\\=\dfrac{15}{2}\times \dfrac{1}{2}\\\\=\dfrac{15}{4} = 3.75\$

Thus, total cost of Mark's board is $3.75.

Bryan sells cars. He makes a salary of $500 a week, plus $150 for every car he sells. This week, he wants to make at least $2000
Kobotan [32]
If Bryan wants to make $2000 dollars then he needs to solve this equation:

2000=500+150x
-500   -500

1500=150x   divide by 150 on both sides

x=10

10 cars

The pitchers for the home team had 12 strikeouts for 32 batters, while the pitchers for the visiting team had 15 strikeouts for
dimulka [17.4K]

Answer:

I disagree with the other answer.

Step-by-step explanation:

The reason for this is because if you have 12/32 for team 1, and 15/35 on team 2, then you do cross products(a type of shortcut).

12/32   15/35

1) Multiply 12 and 35= 420

2) Multiply 15 and 32= 480

3) Which number is greater?

<u>Answer</u>

<em>TEAM 2</em>..(or the visiting team)

A certain club has 10 members, including Harry. One of the 10 members is to be chosen at random to be the president, one of the
ivann1987 [24]

Answer: E) 1/5

Step-by-step explanation:

The probability of any member being selected for each of the 3 posts is 1/10 that is they have equal probabilities of being selected for any of the posts.

The probability that harry would be selected for;

Secretary Ps= 1/10

Treasurer Pt = 1/10

So the probability of being selected for either secretary or treasurer is

P = Ps + Pt

P = 1/10 + 1/10

P = 2/10

P = 1/5

Note: ignore the sequence of selection
