The length of side walk is 500 feet

Solution:

Given that, A rectangle park measures 300 ft by 400 ft

Length = 300 feet

Width = 400 feet

A sidewalk runs diagonally from one comer to the opposite corner

We have to find the length of side walk

Which means, we have to find the length of diagonal of rectangle

The diagonal of rectangle is given by formula:

[tex]d = \sqrt{w^2+l^2}[/tex]

Where,

d is the length of diagonal

w is the width and l is the length of rectangle

Substituting the values in formula, we get

[tex]d = \sqrt{400^2+300^2}\\\\d = \sqrt{160000+90000}\\\\d = \sqrt{250000}\\\\d = 500[/tex]

Thus length of side walk is 500 feet

Answer:

53 teachers

Step-by-step explanation:

Basically, what we need to do here is to find how many teachers there need to be, first. If there are 6,734 students in the school district and if maximum class size is 25, then the number of teachers needed is:

6,734 / 25 = 269.36

Of course, it's obvious that we can't have a decimal number of teachers, so we need to find integer (269 or 270).

If we take 269 teachers and 25 students per class, we get:

269 • 25 = 6,725 students, which is not enough, since there are 6,734 students.

That means that the number of teachers needed is 270.

It is given that there are already 217 teachers, meaning that 270-217=53 teachers have to be supplemented.

52 more teachers must the district have to supplement their staff of 217 teachers.

Given that,

A school district has a student population of 6,734 students.

If the maximum class size is 25 students.

We have to determine,

How many more teachers must the district have to supplement their staff of 217 teachers?

According to the question,

Total number of students = 6,734

Maximum class size = 25 students

Then,

The number of teachers needed is,

[tex]= \dfrac{6734}{25}\\\\= 269.36[/tex]

Here, 269 teachers are needed for each group of 25 students.

Therefore,

The number of more teacher must the district have to supplement their staff of 217 teachers is,

269 - 217 = 52

Hence, 52 more teachers must the district have to supplement their staff of 217 teachers.

Step-by-step explanation:

Answer:

The decimal that represents the unshaded portion of the model is 0.4

Step-by-step explanation:

we know that  

Camille shaded 18/30 of a model

That means

The total parts of the model is equal to 30

The shaded parts of the model is 18

To find out the unshaded parts of the model subtract the shaded parts from the total parts

[tex]30-18=12[/tex]

To find out the decimal that represents the unshaded portion of the model, divide the unshaded parts of the model by the total parts of the model

so

[tex]\frac{12}{30}=0.4[/tex]

Quotient = 2

Solution:

Given expression is [tex]22x^2y^2\div11x^2y^2[/tex].

To find the quotient.

[tex]22x^2y^2\div11x^2y^2=\frac{22x^2y^2}{11x^2y^2}[/tex]

In numerator 22 can be written as 2 × 11.

[tex]\frac{22x^2y^2}{11x^2y^2}=\frac{2\times11x^2y^2}{11x^2y^2}[/tex]

Take common term out in the numerator and denominator.

[tex]\frac{22x^2y^2}{11x^2y^2}=\frac{(11x^2y^2)(2)}{11x^2y^2}[/tex]

Common terms in the numerator and denominator will be cancelled.

[tex]\frac{22x^2y^2}{11x^2y^2}=2[/tex]

Hence the quotient is 2.

Step-by-step explanation:

Answer:

Here, we have used the unit rate i.e. speed of 30 mph to get the distance traveled in 5 number of units i.e. 5 hours.

Step-by-step explanation:

We are asked the way to use a unit rate to solve a rate problem for any number of units.

Let, us assume that a car is moving at a unit rate of 30 miles per hour. And we have to calculate the distance it travels in 5 units of time i.e. 5 hours.

Now, the distance traveled in 5 hours will be given by 30 × 5 = 150 miles.

Answer:

5 liters of water.

Step-by-step explanation:

Let [tex]y[/tex] be the liters of water that must be added to 15 liters of 40% sugar syrup.

Initially, we have [tex]0.4(15)=6[/tex] liters of sugar syrup, and since adding water does not add any new syrup, the amount of sugar syrup must be the same after the water has been added. After the water has been added, 30% of the solution is sugar syrup, or

[tex]Sugar\:syrup =0.3(15+y)[/tex]

And since this must equal the amount of syrup we had before:

[tex]0.3(15+y)=0.4(15)[/tex]

[tex]4.5+0.3y=6[/tex]

[tex]0.3y=1.5[/tex]

[tex]\boxed{y=5}[/tex]

Thus, 5 liters of water must be added to obtain 30% sugar syrup.

Answer:

0.33

Step-by-step explanation:

Aight so all we do is use the formula, as shown here:

[tex]\frac{\Delta x}{\Delta y}[/tex]

[tex]x[/tex] is this amount it changed, which is 0.99. So we plug that for [tex]\Delta x[/tex]:

[tex]\frac{0.99}{\Delta y}[/tex]

Then, we find the amount of times the storm changed, and we plug that for [tex]\Delta y[/tex]:

[tex]\frac{0.99}{3}[/tex]

So, now that we have utilized the formula, we can now solve!

[tex]\frac{0.99}{3} = 0.33[/tex]

The simplified answer is [tex]5\frac{2}{9}[/tex].

Option: C.

Step-by-step explanation:

To simply [tex]-3\frac{1}{9} - (-8\frac{1}{3} )[/tex]:

First convert this improper fraction into normal fraction.

[tex]-3\frac{1}{9}[/tex] = [tex]\frac{-28}{9}[/tex].

[tex]-8\frac{1}{3}[/tex] = [tex]\frac{-25}{3}[/tex].

Now we have to simplify [tex]-\frac{28}{9} - (-\frac{25}{3} )[/tex].

= [tex]-\frac{28}{9} + \frac{25}{3}[/tex].

After applying LCM to the denominators, Multiply the second term with 3 in both numerator and denominator.

= [tex]-\frac{28}{9} + \frac{75}{9}[/tex].

=[tex]\frac{-28+75}{9}[/tex].

=[tex]\frac{47}{9}[/tex].

Convert the answer in improper fraction form.

[tex]\frac{47}{9}[/tex] = [tex]5\frac{2}{9}[/tex].

Thus the simplified answer is [tex]5\frac{2}{9}[/tex].

The missing figure is attached down

The length around the outside of the track is about 431 feet

Step-by-step explanation:

A running track has the shape of a rectangle capped with a semicircle on each end

We need to estimate the length around the outside of the track

The length of the outside the track is the length of two semi-circle and two straight lengths of the rectangle

∵ The track is 80 feet wide

- From the figure the width of the track is the diameter of the

  semi-circles

∴ The diameter of each semi-circle = 80 feet

∵ The radius of a circle is half its diameter

∴ The radius of each semi-circle = [tex]\frac{1}{2}[/tex] × 80 = 40 feet

∵ The length of a circle = 2πr

∴ The length of a semi-circle = πr

∴ The length of two semi-circle = 2 × πr

- Substitute r by 40

∴ The length of two semi-circle = 2 × π(40) = 80π feet

∵ The rectangular portion of the track is 90 feet tall

∴ The length of the rectangle = 90 feet

∴ The two straight parts of the track = 2 × 90 = 180 feet

- Add the length of the two semi-circles and the two straight

   parts to find the length of the track

∵ Length of the track = 80π + 180

- Substitute π by 3.141

∴ Length of the track = 80(3.141) + 180

∴ Length of the track = 431.28 ≅ 431 feet

The length around the outside of the track is about 431 feet

Answer:

The total discounted price is 34.93

Step-by-step explanation:

The items in the cart are:

Total cart = $ 41.10

Discount = 41.10 * 0.15 = $ 6.17

Discounted total price = 41.10 - 6.17

Discounted total price = 34.93

Answer:

34.94.

Step-by-step explanation:

First we must find the total price of all the items: =$6.35+$6.35+$12.50+$13.40+$2.50=$41.10.

Next, we can calculate the discount: =(15/100)×$41.10=$6.165.

Therefore, our discounted price is $41.10−$6.165=$34.935≈$34.94.

There are 5 short essay questions on test

Solution:

Let "a" be the number of multiple choice questions

Let "b" be the number of short essay questions

Worth of each multiple choice questions = 3 points

Worth of each short essay questions = 8 points

There are 25 questions in total

number of multiple choice questions + number of short essay questions = 25

a + b = 25

a = 25 - b --------- eqn 1

The test is worth 100 points. Theerefore, we frame a equation as:

number of multiple choice questions x Worth of each multiple choice questions + number of short essay questions x Worth of each short essay questions = 100

[tex]a \times 3 + b \times 8=100[/tex]

3a + 8b = 100 --------- eqn 2

Let us solve eqn 1 and eqn 2

Substitute eqn 1 in eqn 2

3(25 - b) + 8b = 100

75 - 3b + 8b = 100

5b = 100 - 75

5b = 25

b = 5

Thus there are 5 short essay questions on test

The number of short essay questions on the test is 5.

The science test is worth 100 points and has 25 questions. Let's represent the number of multiple-choice questions as 'x' and the number of short essay questions as 'y'. Each multiple-choice question is worth three points, so the total number of points for the multiple-choice questions is 3x. Each short essay question is worth eight points, so the total number of points for the short essay questions is 8y. We can write two equations to represent the given information:

x + y = 25 (since there are 25 questions in total)

3x + 8y = 100 (since the total points for the test is 100)

To find the number of short essay questions on the test, we need to solve these two equations. By substituting x = 25 - y into the second equation, we can solve for y.

3(25 - y) + 8y = 100

75 - 3y + 8y = 100

5y = 25

y = 5

Therefore, there are 5 short essay questions on the test.
