The 6th graders filled 66% of the seats in the theater on the field trip.

To find the percentage of seats in the theater that were filled by the 6th graders on the field trip, we can use the following formula:

Percentage = (Filled Seats / Total Seats) * 100

Filled Seats = 2112

Total Seats = 3200

Substituting the values into the formula:

Percentage = (2112 / 3200) * 100

Percentage = 0.66 * 100

Percentage = 66%

The 6th-grade students filled approximately 66 percent of the 3200 seats in the theater during their field trip to see the ballet.

Use the concept of percentage defined as:

A figure or ratio that may be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.

The proportion, therefore, refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

Given that,

A middle school took its 6th-grade students on a field trip to see a ballet.

The field trip took place at a theater.

The theater has a total of 3200 seats.

The 6th-grade students filled 2112 of the seats in the theater.

To calculate the percentage of seats filled by the 6th-grade students:

Use the formula =  (Number of seats filled / Total number of seats) x 100.

In this case,

The number of seats filled by the 6th-grade students is 2112, and the total number of seats in the theater is 3200.

Put the values, we get,

(2112 / 3200) x 100 = 66%

Hence

The 6th graders filled approximately 66% of the seats in the theater.

Performing LCM, the least number of pencils and pens that she needs to buy are 60 pencils and 60 pens.

LCM refers to the least common multiple. The LCM of two or more numbers is the one that can divide all the numbers by the single number itself.

Pencils come in packages of 20 and pens come in packages of 12.

So, the possible lowest common multiplier is LCM of 20 and 12, and it is 60.

So she has to buy 3 packages of pencils (60/20 = 3 ) as well 5 packages of pens ( 60/12 = 5 ).

Pythagorean theorm can be applied here to solve for the length of the last leg, [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex], where (a) and (b) are the legs of the triangle and (c) is the hypotenuse. We can rearrange the pythagorean theorm for our purposes like the following:

A two–way table that shows data from Leslie's survey is presented as follows;

Dog. No dog Total

Cat. 17. 24. 41

No cat. 30. 9. 39

Total 47. 33. 80

The given parameters are;

Solution;

The number that have dogs and no cat = 47 - 17 = 30

Therefore, we have;

Dog and cat = 17

No dog and cat = 24

No dog no cat = 9

Total number that have cats = 17 + 24 = 41

Number that have no cats = 30 + 9 = 39

Sum total of students that have no dogs = 24 + 9 = 33

The volume in cubic yards of concrete needed is 3.5 cubic yards

From the question, we are to calculate the volume of concrete needed

From the given information,

A new concrete courtyard will be 15' by 25'

That is,

15 feet by 25 feet

Also, from the given information,

The concrete will be filled to a depth of 3" (1/4 foot.)

That is, 0.25 foot

First, we will convert the measurements to yards

NOTE: 1 foot = 1/3 yards

Thus,

15 feet = 15/3 yards = 5 yards

25 feet = 25/3 yards

0.25 foot = 0.25/3 yard = 1/12 yards

Thus,

Volume of concrete needed = 5 × 25/3 × 1/12

Volume of concrete needed = 125/36

Volume of concrete needed = 3.472 cubic yards

Volume of concrete needed ≈ 3.5 cubic yards

Hence, the volume in cubic yards of concrete needed is 3.5 cubic yards

Solving for the variable 'f' gives f = 100 - 2h/5

A subject of formula can be defined as the variable that is expressed in terms of other variables in a given expression, function of equation.

It is the variable that is worked out in an equation and left to stand on its own on one side of the equality sign

Given the equation;

5f+2h = 100

To make 'f' the subject of formula, we take the following steps;

Take '2' over the equality sign

5f = 100 - 2h

Now, let's make 'f' the subject by dividing both sides by its coefficient which is 5

We have;

5f/5 = 100 - 2h/5

Divide through

f = 100 - 2h/5

Thus, solving for the variable 'f' gives f = 100 - 2h/5

Answer:

y - 4 = -8/7(x - 4)

Step-by-step explanation:

Point-Slope form: y - y₁ = m(x - x₁)

x₁ and y₁ would be the coordinates of the point (4,4).

m would be the slope -8/7.

Substituting these values:

y - 4 = -8/7(x - 4)

Answer:

B

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = - [tex]\frac{8}{7}[/tex] and (a, b) = (4, 4) , then

y - 4 = - [tex]\frac{8}{7}[/tex] (x - 4) → B

Step-by-step explanation:

The probability that a person who tests positive is infected is 0.0843.

Suppose the incident rate of a certain disease is 0.1 %.

The false negative rate is 8 % and the false positive rate is 1 %.

For a population of 100,00

There are 0.1 % infected = 100,00 × 0.1 % = 100

The population that is not infected is:

= 100,000 - 100 = 99900

The false negative rate is 8%, so the positive rate is 100 = 8 = 92%.

The population that is infected and has a positive result is:

= 100 × 0.92 = 92

The false positive rate is 1%.

The population that is not infected but has a positive result is:

= 99900 × 0.01 = 999

Therefore, the total positive results are:

= 92 + 999 = 1091

Therefore, the probability that a person who tests positive actually is infected is:

P ( infected / positive) = 92 / 1091 = 0.0843

Hence, the probability that a person who tests positive is infected is 0.0843.

Answer:

The 15% discount means that they only pay 100%-15% = 85% of the meal's bill.

This would cost 85% * 78.65.

However, they also have to pay a 20% tip of the meal cost.

This would cost 20% * 78.65.

Step-by-step explanation:

total Cost = (85% * 78.65) + (20% * 78.65)

= 105% * 78.65

= 1.05 * 78.65

∠6=116°

Step-by-step explanation:

Buckle up :)

[tex]-2x+94=-5x+139[/tex]

Solve for x. Subtract 94 from both sides:

[tex]-2x+94-94=-5x+139-94\\\\-2x=-5x+45[/tex]

Add 5x to both sides:

[tex]-2x+5x=-5x+5x+45\\\\3x=45[/tex]

Divide both sides by 3:

[tex]\frac{3x}{3} =\frac{45}{3} \\\\x=15[/tex]

Insert the value of x into angle 4 because they are same-side interior angles. This is because they are on the same side of the transversal and within the parallel lines. Same-side interior angles are supplementary, so their value will add up to 180°. Therefore, in order to find angle 6, we need to first find the true value of angle 4:

[tex]x=15\\\\-2(15)+94\\\\-30+94\\\\64[/tex]

∠4 is 64°. Use ∠a+∠b=180 to find angle 6:

[tex]a+64=180[/tex]

a represents angle 6. Subtract 64 from both sides:

[tex]a+64-64=180-64\\\\a=116[/tex]

Angle 6 has a measure of 116°.
