76 is 80% of what number?

1 answer:

8 0

76 is 80% of 95 and I'll even explain.
80/100 = 76/x from this point you cross multiply which gives you 80x = 76(100) you multiply 76 by 100 and get 7600 so then the equation look like this 80x = 7600 then divide by 80 on both sides and get the answer of x = 95 which is basically your answer I hope this helps :)

Solve the following maximization problem graphically.

rjkz [21]

The maximized value of the function is (c) 119/2

<h3>Maximization problem</h3>

Maximization problems are used to determine the optimal solution of a linear programming model

<h3>Objective function</h3>

The objective function is given as:

$P(x,y) = 11x + 10y$

<h3>Constraints</h3>

The constraints are given as:

$22x + 2y \le 68$

$8x + 16y \le 68$

$x,y\ge 0$

<h3>Graph</h3>

See attachment for the graph of the constraints

From the graph, the optimal solution is: (2.83, 2.83)

So, the maximized value is:

$P(x,y) = 11x + 10y$

$P =11 \times 2.833 + 10 \times 2.833$

$P =59.493$

Approximate

$P =59.5$

Rewrite as a fraction

$P =\frac{119}{2}$

Hence, the maximized value of the function is (c) 119/2

If 10% of all machines become worthless every year (they depreciate, in other words), then how many machines will become worthle

nikklg [1K]

Answer: Country A - 10machines

Country A - 1,000machines

Country A - 10,000machine

step-by-step explanation:

Since 10℅ of all machines becomes worthless every year, let's look at each country.

If 100 machines are all the machines in country A, then 10% of all the machines in country A (i.e 100 machines) will be 10% of 100 = 10 machines.

Similarly for country B, it will be equivalent to 10% of 10000, which is equal to 1,000machines.

Same goes for country C i.e 10% of 1000000 = 10,000machines are worthless.

In RSM camp, there are four counselors for every fifty seven students and three teachers for every five counselors. Chapter Refe

max2010maxim [7]

The number of students attending the camp that summer is 380 students

Step-by-step explanation:

There are four counselors for every fifty seven students

There are three teachers for every five counselors

Ms. Rifkin asked all 16 teachers present at the camp to attend a

teachers meeting

To solve this question we will use the ratio

The given is:

1. 4 counselors for every 57 students

2. 3 teachers for every 5 counselors

3. There are 16 teachers

At first let us find the 16 teachers are for how many counselors

∵ 3 teachers : 5 counselors

∵ 16 teachers : x counselors

∴ $\frac{3}{5}=\frac{16}{x}$

By using cross multiplication

∴ 3x = 16 × 5

∴ 3x = 80

Divide both side by 3

∴ x = $\frac{80}{3}$

Then let us find the $\frac{80}{3}$ counselors are for how many students

∵ 4 counselors : 57 students

∵ $\frac{80}{3}$ counselors : y students

∴ $\frac{4}{57}=\frac{80/3}{y}$

By using cross multiplication

∴ 4y = 57 × $\frac{80}{3}$

∴ 4y = 1520

Divide both sides by 4

∴ y = 380 students

The number of students attending the camp that summer is 380 students
