the answer is 4953 * 100 which is equal to 495300

Answer:

The Number written by lance = 4,953

Face value of ,9 in 4953 = 9

Place value of , 9 in 4953 = 9 × 100=900

So, the number could be

1. 100 × Face value of , 9 in 4,953 = 100 × 9=900

2. 100  × Place value of , 9 in 4,953 =100 × 900=90,000

Answer: 18 parent volunteers and 4 buses.

Step-by-step explanation: In order to solve this problem you must first calculate how many student will be going on the trip.

There are 8 classes of 20 students and 90% are attending, so the formula is 8 x 20 x .9 = 144 students are going.

Part A: If one parent needs to go for each 8 students you need to divide 144 by 8 = 18 parent volunteers.

Part B: The total people attending are 144 students, 18 parent volunteers and 4 teachers is a total 166 total attending to ride the bus. You need to divide 166 people by 44 on each bus = 166/44 = 3.7 buses, so they need to reserve 4 buses.

Answer:

1 pound

Step-by-step explanation:

12/3= 4

16/4=4

4/4=1

To find the weight of the frame nails that Dylan bought, which is 3/4 of the total weight of 12/16 pound, we multiply the total weight by 3/4 to get 9/16 pound.

The subject of this question is mathematics and it appears to be aimed at a middle school level. Dylan bought a total of 12/16 pound of plywood nails and frame nails, and we are asked to determine the weight of the frame nails, which is 3/4 of the total weight. To find the weight of the frame nails, you simply multiply the total weight by 3/4:

Therefore, the weight of the frame nails is 9/16 pound.

Answer:

Step-by-step explanation:

First Question

The top question has 2 solutions because eventually you will have to take the square root of (x - 4)^2. One square root will be plus, and the other minus

(x - 4)^2 - 28 = 8                 Add 28 to both sides

(x - 4)^2 -28+28 = 8+28     Collect like terms

(x - 4)^2 = 36                       Take the square root.

sqrt( (x - 4)^2 ) = sqrt(36)    

x - 4 = +/- 6

=============

x - 4 = + 6      

x = 6 + 4

x = 10

============

x - 4 = - 6

x = - 6 + 4

x = - 2

The two solutions are (10,0) and (-2,0)

Second Question

The question is solved correctly up to the point where the square root needs to be taken. It is incorrect at that point.

x^2 - 6x - 7 = 0                             Add 7 to both sides.

x^2 - 6x  = 7                                  Add 1/2 the linear term and square it to both sides.

x^2 - 6x + (6/2)^2 = 7 + (6/2)^2    Expand the right

x^2 - 6x + 3^2 = 7 + 9                    

x^2 - 6x + 9 = 16                            express the square on the left

(x - 3)^2 = 16                                   Take the sqrt of both sides.

x - 3 = sqrt(16)

x - 3 = +/-4

============

x - 3 = 4

x = 4 + 3

x = 7

===========

x -3 = - 4

x = - 4 + 3

x = - 1

==========

Use long multiplication to evaluate

Answer:

8.3 cm

Step-by-step explanation:

The equation 2πr is used to find circumference. To find the diameter, you will first need to find the radius, and in order to find the radius, you need to isolate "r" in the equation.

2πr = 26

Divide 2 for both sides.

πr = 13

Divide π (I am assuming π is 3.14) for both sides.

r = 4.140127389

Our radius is about 4.140127389. To find the diameter, multiply your radius by 2. This gives us 8.276057041, which rounds to 8.3 cm.

The length of UC is 18

First we are going to find the length of JN; then we are subtracting from it the length of JU plus the length of CN.

We can infer from our picture that JN is 82 + 105, so JN = 187

We can also infer that JU = JH + HU

                                     JU = 22 + 96

                                     JU = 118

We can also infer that CN = 51

Now we can fin the length of UC:

[tex]UC=JN-(JU+CN)[/tex]

[tex]UC=187-(118+51)[/tex]

[tex]UC=18[/tex]

We can conclude that the length of UC is 18.

Answer:

The correct answer is UC = 18

Step-by-step explanation:

From the given figure we can see that,

total length JN =  82 + 105 = 187

To find the length UC

From figure we can write,

UC = Total length - ( JU + CN) = JN - ( JU + CN)

JU = JH + HU = 22 + 96 = 118

UC = JN - ( JU + CN)

     = 187 - (118 + 51)

     = 187 - 169 = 18  

Therefore the length of UC = 18

Answer:

x = 10

Step-by-step explanation:

Given

4x + 8y = 40 ← substitute y = 0, then

4x + (8 × 0) = 40

4x + 0 = 40

4x = 40 ( divide both sides by 4 )

x = 10

Answer:

Answer:

x = 200

y = 100

Step-by-step explanation:

20x + 30y = 7000       Divide by 10

15x + 35y = 6500       Divide by 5

===============

It helps if you break down both equations to something simpler. It looks like not always.

(2x + 3y = 700)              Multiply by 3            

(3x + 7y = 1300)             Multiply by 2

==================

6x + 9y = 2100

6x + 14y =2600              Subtract

-5y = - 500                     Divide by -5

-5y/-5 = -500/-5

y = 100

2x + 3y = 700                  substitute y = 100

2x+ 3*100 = 700              Combine

2x + 300 = 700                 Subtract 300 from both sides.

2x = 700 - 300

2x = 400

x = 400/2

x = 200

===================

Hockey check

15x + 35y = 6500

15*200 + 35*100 = 6500

3000 + 3500 = 6500      Just as it should.  

Answer: 300 seats

Step-by-step explanation:

Easy!

20x + 30y = 7000

15x + 35y = 6500

Simplify by division of a common factor:

5(4x + 6y = 1400)

5(3x + 7x = 1300)

Choose an equation to solve for a variable and use substitution:

4x = 1400 - 6y

x = 350 - 3/2y

3(350 - 3/2y) + 7y = 1300

1050 - 9/2y + 7y = 1300

5/2y = 250

y = 100

Now substitute the solution in both equations to see if it works:

20x + 30(10) = 7000

20x + 3000 = 7000

20x = 4000

2x = 400

x = 200

Now for the other equation:

15x + 35(100) = 6500

15x + 3500 = 6500

15x = 3000

x = 200

Now add x to y, as the total number of seats is equal to x + y.

x + y = total number of seats.

200 + 100 = 300

Therefore, there must be 300 seats in total.

Option d -  720/750 ≈ 0.96                    

Step-by-step explanation:

Given : Of 750 people surveyed, 330 were male and 640 had cell phones. Of those with cell phones, 390 were female.

To find : What is the probability that a person surveyed was either male or had a cell phone?

Solution :

Let M be the number of males i.e. M=330

Let C be the number of cell phones i.e C=640

Total number of people = 750

Of 750 people surveyed, 330 were male

The probability of male is

[tex]P(M)=\frac{330}{750}[/tex]

Of 750 people surveyed, 640 had cell phones

The probability of cell phones is

[tex]P(C)=\frac{640}{750}[/tex]

Of those with cell phones, 390 were female.

i.e. reaming were male so 640-390=250

So, Probability of male and cell phone is

[tex]P(M\cap C)=\frac{250}{750}[/tex]

We have to find, the probability that a person surveyed was either male or had a cell phone i.e. [tex]P(M\cup C)[/tex]

Using formula,

[tex]P(M\cup C)=P(M)+P(C)-P(M\cap C)[/tex]

Substitute the values,

[tex]P(M\cup C)=\frac{330}{750}+\frac{640}{750}-\frac{250}{750}[/tex]

[tex]P(M\cup C)=\frac{330+640-250}{750}[/tex]

[tex]P(M\cup C)=\frac{720}{750}[/tex]

[tex]P(M\cup C)=0.96[/tex]

Therefore, Option d is correct.

Answer:

-7

Step-by-step explanation:

To find f(-8), use the blue line labeled f(x) and go to -8 on the x axis and find its corresponding y value by moving vertically down from -8 to the blue line and find the y value of that point. You can see that the blue line hits (-8, -5) so the y value is -5 and f(-8) = -5.

Do the same thing for g(4) and you should find the red graph g(x) hits the point (4, 3). So g(4) = 3.

-1 * -5 - 4 * 3 = 5 - 12 = -7

The volume of the given figure is: 126π cubic inches.

A volume is defined as a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

The volume of the attached figure will be the sum of the volume of the cylinder and twice the volume of the hemisphere. Therefore, the volume will be:

Volume = Volume of cylinder + 2(Volume of hemisphere)

Answer:

42 miles.

Step-by-step explanation:

It is given that Mr. and Mrs. Rivers left their house at 10:00 a.m. driving in opposite directions.

Speed of Mr. Rivers = 48 mph

Speed of Mrs. Rivers = 36 mph

We need to find the distance between them at 10:30 a.m.

10:30 - 10:00 = 0:30 = 30 minutes = 1/2 = 0.5 hour

Distance covered by Mr. Rivers in half hour = 48 × 0.5 = 24

Distance covered by Mrs. Rivers in half hour = 36 × 0.5 = 18

Total distance covered by both in half hour = 24 + 18 = 42

Therefore, they are 42 miles far from each other at 10:30 a.m.

Answer:

42 miles

Step-by-step explanation:

f(x)= 9x^3+ 2x^2 -5x+ 4

g(x)= 5x^3 -7x+ 4

f(x) - g(x)

= (9x^3+ 2x^2 -5x+ 4) - (5x^3 -7x+ 4)

= 9x^3+ 2x^2 -5x+ 4 -5x^3+ 7x -4

= (9x^3 -5x^3)+ 2x^2+ (7x -5x)+ (4-4) (combine like terms)

= 4x^3+ 2x^2+ 2x

= 2x* (2x^2+ x+ 1)

The final answer is 2x* (2x^2+ x+ 1).

This is pretty easy, we have two steps.

#1. We have to use the formula rule.

4 x 8 + 1. over 8.
