In this case, you need to find the percentage each student got, then find who received a higher score.

First Step: $\frac{85}{95}$ (and) $\frac{64}{76}$
Second step: Divide each fraction → ≈ 0.8947 (and) ≈ 0.8421
Third Step: Multiply each decimal by 100. → 89.47% (and) 84.21%

Fourth Step: As 89.47% is greater, Author got an higher score.

Marcy has 150 to buy packages of hotdogs and hamburgers for her booth at the carnival. Grocery store she found packages of hotdo

bekas [8.4K]

Answer:

Part (A): The required equation will be: $6d+20b=150$

Part (B):The required equation will be: $d=\frac{150-20b}{6}$

Part (C):The required equation will be: $b=\frac{150-6d}{20}$

Step-by-step explanation:

Consider the provided information.

Let d represents number of packages of hot dogs and b represents the number of packages of hamburgers.

Part (a)

It is given that the cost of a package of hot dogs is $6 and cost of a package of hamburger is $20.

The required equation will be: $6d+20b=150$

Part (b) Solve the above equation for d.

Subtract 20b from both sides.

$6d=150-20b$

Divide 6 from both sides.

$d=\frac{150-20b}{6}$

The required equation will be: $d=\frac{150-20b}{6}$

Part (c) Solve the equation for b.

Subtract 6d from both sides.

$20b=150-6d$

Divide 20 from both sides, we get

$b=\frac{150-6d}{20}$

The required equation will be: $b=\frac{150-6d}{20}$

in a class experiment, Sean finds that the probability that a student plays soccer is 12/25. if the school population is 300, ho

fgiga [73]

Okay, here we have this:

Considering the provided information, we are going to calculate the requested value, so we obtain the following:

Then we will substitute in the following formula:

Students who play soccer=Number of students*(Probability that they play soccer)

Replacing:

Students who play soccer=300*(12/25)

Students who play soccer=3600/25

Students who play soccer=144

Finally we obtain that 144 students would we expect to play soccer, based on Sean's experiment.
