Answer:

x ≈ 3.4 mm

Step-by-step explanation:

using the Sine Rule in the triangle

[tex]\frac{x}{sin27}[/tex] = [tex]\frac{7.1}{sin73}[/tex] ( cross- multiply )

x × sin73° = 7.1 × sin27° ( divide both sides by sin73° )

x = [tex]\frac{7.1sin27}{sin73}[/tex] ≈ 3.4 mm ( to 1 dec. place )

It's 24.3 try it.

Hope this helps!

Please give brainliest, i need 3 more :)

Answer:

24.3

Step-by-step explanation:

Here we need to evaluate,

[tex]\longrightarrow 3^3 +14.7\div 7-(1.2\times 4)[/tex]

First of all we need to know about BODMAS , which stands for ,

B = BracketsO = of D = divisionM = multiplicationA = AdditionS = Subtraction

This means first we need to solve brackets , then of , then division , then multiplication, then addition and finally subtraction.

In the given questions, firstly solve the terms inside the brackets ,

[tex]\longrightarrow 3^3 +14.7 \div 7 -(1.2\times 4)[/tex]

Multiply 1.2 and 4 ,

[tex]\longrightarrow 3^3+14.7\div 7-(4.8) [/tex]

Now perform division , that is divide 14.7 by 7

[tex]\longrightarrow 3^3 + 2.1 - 4.8 [/tex]

Simplify 3³ .

[tex]\longrightarrow (3)(3)(3)+2.1-4.8= 27+2.1-4.8[/tex]

Add ,

[tex]\longrightarrow 29.1 -4.8[/tex]

Finally subtract,

[tex]\longrightarrow \underline{\underline{\boldsymbol{ 24.3 }}}[/tex]

And we are done!

Answers

Hi! Hope this helps

(- stands for negative and + stands for positive)

Adding

- plus + = - or + depending on the numbers (If you have -7 + 3 it equals -4, but -3 + 7 = 4)

+ plus + = + (Simple)

- plus - = - (Like regular addition, except -2 + -3 would be -5)

Subtraction

- minus + = - (If you have -7 - 3 it equals -10, and -3 - 7 = -10)

- minus - = + (If you have -3 - (-4) = 1)

+ minus + = - or + depending on the numbers ( If you have 8 - 4 it equals 4, but if you subtract 8 from 4, it is -4

Please Help Me, This Is So Difficult.

A tourism agency can sell up to 1500 travel packages for the Sugar Bowl college football postseason game in New Orleans. The package includes airfare, weekend accommodations, and the choice of two types of flights: a nonstop flight or a two-stop flight. The nonstop flight airplane can carry up to 150 passengers, and the two-stop flight airplane can carry up to 100 passengers. The agency can locate no more than 12 planes for the travel packages. The tourism company makes a profit of $1100 for each non-stop flight airplane sold and $800 for each two-stop flight airplane sold. Assume that each plane will carry the maximum number of passengers.

Define the variables for this situation.

Write a system of linear inequalities to represent the constraints.

Graph the system of linear inequalities and shade the feasible region that shows the area of the graph representing valid combinations of nonstop and two-stop flight packages. Be sure to label your axes with correct increments.

Write an objective function that maximizes the revenue for the tourism agency.

Find the maximum revenue for the given constraints and give the combination of flights that achieves this maximum.

The maximum revenue would be _______________ and would be achieved using _____ nonstop flights and _____ two-stop flights.

Answers

The maximum revenue would be $9600 and would be achieved using 0 nonstop flights and 12 two-stop flights.

How to define the variables

Let x = number of non-stop airplanes

Let y = number of two-stop airplanes

The system of linear inequalities

Using the variables in (a), we have the following constraints

Total passenger constraint: 150x + 100y <= 1500

Total Airplanes constraint: x + y <= 12

Graph the feasible region.

In (b), we have the following system of linear inequalities

150x + 100y <= 1200

x + y <= 12

See attachment for the graph

The objective function

The objective function of the constraints is:

Max z = 1100x + 800y

The maximum revenue

From the graph of the function, the optimal solution is:

(x,y) = (0,12)

So, the maximum revenue is:

z = 1100x + 800y

z = 1100*0 + 800*12

z = 9600

Hence, the maximum revenue is $9600

Mrs. Adesso wants to take her class on a trip to either the science center or natural history museum. The science center charges $7 per student, plus $75 for a guided tour. The natural history museum charges $8 per student, plus $50 for a guided tour. For what number of students is the cost of the trip the same at each museum?

Answers

Answer:

Step-by-step explanation:

When we write expressions for the total cost of each field visit and set them equal, we find the solution to be the ratio of the difference in fixed cost to the difference in variable cost.

y = 75 +7x . . . . . cost for x students to visit the science center

y = 50 +8x . . . . cost for x students to visit the natural history museum

Subtracting the first equation from the second, we get ...

0 = -25 +x

25 = x . . . . . add 25; the number of students such that costs are equal

The cost will be the same either place for 25 students.

Additional comment

Here, the fixed cost difference is 75-50=25, and the variable cost difference is 8-7=1. The ratio of these costs is ...

$25/($1 /student) = 25 students.

This relationship only holds when the higher fixed cost is associated with the lower variable cost. Charges are such that one place caters to larger numbers of students (science center), and one prefers fewer students (natural history museum).

Eddie and Janice are buying school supplies. Eddie buys 5 notebooks and 6 binders for a total of $25.45. Janice buys 4 notebooks and 8 binders for $30.60. What is the cost of each item?

Answers

Answer:

Notebook $1.25

Binder $3.20

Step-by-step explanation:

5n + 6b = 25.45

4n + 8b = 30.6

Multiply the first equation by -4.

Multiply the second equation by 5.

Add the equations.

-20n - 24b = -101.8

20n + 40b = 153

16b = 51.2

b = 3.2

5n + 6(3.2) = 25.45

5n + 19.2 = 25.45

5n = 6.25

n = 1.25

Answer:

Notebook $1.25

Binder $3.20
