Answer:

4725

Step-by-step explanation:

105 students

think of 100 students

100 × 45 = 4500

now the remaining 5 students

cost for 10 students will be

45 × 10 = 450

divide 450 by 2 to find out for 5 students

it is 225

4500 + 225 = 4725

Answer:

A = 11

B = 8

Step-by-step explanation:

The function is 2[tex]2x^2 + x + 5[/tex]

To determine y=A and y=B simply substitute the value of x corresponding to that y-value

A is at x = -2

At x = -2,
[tex]\mathsf =2\left(-2\right)^2+\left(-2\right)+5[/tex]
= [tex]2\cdot \:4+\left(-2\right)+5[/tex]

[tex]= 8 - 2 + 5[/tex]
[tex]= 11[/tex]

So [tex]\boxed{A = 11}[/tex]

For B, note that x = 1

So y-value for x = 1 is

[tex]y = 2\cdot \:1^2+\:1+5[/tex]
[tex]=2\cdot \:1+1+5[/tex]

[tex]=2+1+5[/tex]

[tex]=8[/tex]

So [tex]\boxed{B=8}[/tex]

Height of the base = 10cm

The definition of triangular volume?

Given a candy box is in the shape of triangular prism

           Volume of the box = 1200 cm³

           Base of the triangle = 10cm

           Side of the triangle = 13cm

           Length of the box = 20 cm

            Let the height of the base = h cm

Volume of the triangular prism = 1/2×(Base of triangle)×(Height of triangle)×(length of prism)

   1200 = (1/2)×10×h×20

        1200 = 100h

      h = 1200/100

      h = 12 cm  

        So, height of the triangle = 10cm

Answer:

  3/5 < 3/4   (The symbol you need is <.)

Step-by-step explanation:

The problem is asking you to compare the fractions 3/5 and 3/4. You need to supply a comparison symbol, one of {<, =, >}.

In general, when you are asked to compare two values, you are being asked which one is greater (or smaller). Sometimes, you are being asked for the amount by which one is greater than the other (their difference), and sometimes you are being asked for the factor by which one is greater than the other (their ratio).

You can do the arithmetic to find the appropriate difference or ratio, or you can use your number sense to identify the larger (or smaller) number.

As you know, the denominator of a fraction tells you how many pieces the pie has been divided into.

In the fraction 3/5, the 5 tells you each piece is 1/5 of the whole, that there are 5 equal pieces.

In the fraction 3/4, the 4 tells you each piece is 1/4 of the whole, that there are 4 equal pieces.

A pie divided into 5 pieces instead of 4 has smaller pieces. That is ...

  1/5 < 1/4

When there are 3 pieces of each, this relation still holds:

  3×(1/5) < 3×(1/4)   ⇒   3/5 < 3/4

__

Additional comment

Here, the numerators are the same, so we only need to compare the denominators to find the relationship. If the denominators are the same, we can compare the numerators.

If neither is the same, it is often useful to multiply one or the other or both of the fractions by some value so they will have a common numerator or denominator. The usual recommendation is to give the fractions a common denominator.

Here, the denominators can be made to be 20 in each case.

  [tex]\dfrac{3}{5}=\dfrac{3}{5}\cdot\dfrac{4}{4}=\dfrac{12}{20}\\\\\dfrac{3}{4}=\dfrac{3}{4}\cdot\dfrac{5}{5}=\dfrac{15}{20}[/tex]

The denominators are now the same, so we can compare values by comparing the numerators. 12 < 15, so 12/20 < 15/20 and 3/5 < 3/4.

The value of x is 3 days.

Here,

Jenna alone takes x days to finish a project.

Kelly alone takes 3 days more than Jenna alone to finish the project.

They together take 2 days to finish the project.

We have to find the value of x.

What is Mathematical expression?

Mathematical expression is a way where calculations and analytical processes should be observed.

Now,

Jenna alone takes x days to finish a project.

Hence, Jenna complete work in 1 day = 1/x work

Kelly alone takes 3 days more than Jenna alone to finish the project.

That is, x + 3 days.

Hence, Kelly complete work in 1 day = [tex]\frac{1}{x+3}[/tex] work

They together take 2 days to finish the project.

Hence, They together complete a work in 1 day = 1/2 work.

To find the value of x we use the formula of work word problem as;

[tex]\frac{1}{x} + \frac{1}{x+3} = \frac{1}{2} \\\\\frac{(x+3)+x}{x(x+3)} = \frac{1}{2}\\\\2(2x+3) = x (x+3)\\\\4x + 6 = x^{2} + 3x\\\\x^{2} -x-6=0\\\\x^{2} -3x+2x-6=0\\\\x (x-3) +2(x-3)=0\\\\(x+2) (x-3) = 0\\\\x = -2, x = 3[/tex]

Since, The value of x = -2 is not possible (because days are not shown in negative sign).

Hence, The value of x is 3 days.

cos = 4/5

Step-by-step explanation:

having sides 3 and 5, means that this is a right triangle with sides 3,4, and 5

cos = adjacent side/ hypotenuse

sin= opposite side/ hypotenuse

since 5 is the biggest number it will be the hypotenuse since that is the longest side, so it will stay on the bottom.

The given triangle is 6.5 ft2.

Having three sides, three angles, and three vertices, a triangle is a closed, two-dimensional object. A polygon includes a triangle. Triangles have three sides. The sides of the triangle ABC are AB, BC, and CA.

The given triangle can be redraw as

Area of the rectangle is (39/2) × 48 (in)2 = 936 in2

1 ft = 12in

1/12 ft = 1in

(in)2 = (1/12)2 (ft)2

          = 1/144 (ft)2

936 (in)2 = 936 × 1/144 (ft)2

The value is 3600

According to question ,

given that, Depreciation for the current year is $ 3100

accumulated depreciation equipment is $ 6700

Unadjusted balance of December

 6700 - 3100 = 3600

Depreciation is the process of deducting the total cost of something expensive you bought for your business. But instead of doing it all in one tax year, you write off parts of it over time. When you depreciate assets, you can plan how much money is written off each year, giving you more control over your finances.

Formula: (asset cost – salvage value) / useful life

explain the formula:  You divide the cost of an asset, minus its salvage value, over its useful life. That determines how much depreciation you deduct each year.

Accumulated depreciation is the total amount an asset has been depreciated up until a single point. Each period, the depreciation expense recorded in that period is added to the beginning accumulated depreciation balance

The measure of the angle 8 is option (d). 106.

Measure of Angle

Angle measurement is the amount of rotation from the initial to an endpoint of a ray.

Given,

Measure of Angle 2 = 8x + 10

Measure of angle 6 = x² - 38

Here we need to find the measure of angle 8.

Let us consider the angle 2 and 6 are corresponding angles.

Then,

Measure of Angle 2 = Measure of Angle 6

Apply the corresponding values,

Then we get,

8x + 10 = x² - 38

It can be written as,

=> x² - 38 - 8x - 10 = 0

=> x² - 8x - 48 = 0

When we factorize the equation,

Then we get,

=> (x + 4) ( x - 12) = 0

Then the value of x will be x = -4 and 12.

Here the value of x can't be negative.

So,

=> x = 12

Now apply the value of x on the measure of angle 2,

=> 8(12) + 10

=> 96 + 10

=> 106

So, the measure of angle 8 is option (d). 106.

According to the statement:

Mode measure of central tendency would be appropriate to summarize the measurements.

The correct option is B.

We can't use mean or median because they have no physical meaning, i.e., eyes that are somewhere between black and white.

When you need to use all of the data's values, you would use the mean. When you only need to use two values, such as the upper and lower values, you would use the median. And when ones data is unobservable, such as when you need to determine peoples' opinions, you would use the mode.

Add up all the values inside the data set, then divide by the total number of values to find the mean. List the data set's values in numerical order, and then find the value that sits in the middle of the list to determine the median. Choose the data set value that appears the most frequently to determine the mode.

Answer:

The smaller number is 27 and the larger number is 44

Step-by-step explanation:

Let x = the larger number

Let y = the smaller number

x + y = 71

x = y + 17  Substitute in y + 17 for x in the first equation.

x + y = 71

y +17 + y = 71  Combine the y's.

2y + 17 = 71  Subtract 17 from both sides of the equation

2y = 54  Divide both sides of the equation by 2

y = 27.  Plug 27 in for y for either of the two original equation to find x

x + y = 71

x + 27 = 71  Subtract 27 from both sides of the equation

x = 44
