Round 763,400 to nearest ten thousand explain

Mathematics
1 answer:
Ganezh [65]3 years ago
5 0
Okay, so we first need to locate which number is in the ten thousand place.
Ten thousand, is this 10, 000, right? Well that number has 5 digits.
Now go back to 763,400 and starting from the right, count the first 5 digits.
You should stop at the 6.
the rest is easy! Look to the right of 6, there's a 3. Since 3 is less than 5,  you will not round the 6 up to 7. 
SO, you keep the 7 and the 6, but turn the rest of the numbers after 6 into 0s.
Your answer should be 760,000!

I hope I made sense, if not, I will clarify anything you did not understand!

What is the equation of a line that passes through the points (3, 6) and (8, 4) in slope intercept form?
MrMuchimi

Answer:

y=-\frac{2}{5}x +8.4

Step-by-step explanation:

Gradient

m =\frac{y-y1}{x-x1}

m = \frac{6-4}{3-8}

m=-\frac{2}{5}

Equation of a line

(y-y1)=m(x-x1)\\

- Sub one set of points into equation

(y-6)= -\frac{2}{5} (x-6)

y=-\frac{2}{5}x +8.4

Simplify: cos2x-cos4 all over sin2x + sin 4x
GrogVix [38]

Answer:

\frac{\cos\left(2x\right)-\cos\left(4x\right)}{\sin\left(2x\right)+\sin\left(4x\right)}=\tan\left(x\right)

Step-by-step explanation:

\frac{\cos\left(2x\right)-\cos\left(4x\right)}{\sin\left(2x\right)+\sin\left(4x\right)}

Apply formula:

\cos\left(A\right)-\cos\left(B\right)=-2\cdot\sin\left(\frac{A+B}{2}\right)\cdot\sin\left(\frac{A-B}{2}\right) and

\sin\left(A\right)+\sin\left(B\right)=2\cdot\sin\left(\frac{A+B}{2}\right)\cdot\sin\left(\frac{A-B}{2}\right)

We get:

=\frac{-2\cdot\sin\left(\frac{2x+4x}{2}\right)\cdot\sin\left(\frac{2x-4x}{2}\right)}{2\cdot\sin\left(\frac{2x+4x}{2}\right)\cdot\cos\left(\frac{2x-4x}{2}\right)}

=\frac{-\sin\left(\frac{2x-4x}{2}\right)}{\cos\left(\frac{2x-4x}{2}\right)}

=\frac{-\sin\left(\frac{-2x}{2}\right)}{\cos\left(\frac{-2x}{2}\right)}

=\frac{-\sin\left(-x\right)}{\cos\left(-x\right)}

=\frac{-\cdot-\sin\left(x\right)}{\cos\left(x\right)}

=\frac{\sin\left(x\right)}{\cos\left(x\right)}

=\tan\left(x\right)

Hence final answer is

\frac{\cos\left(2x\right)-\cos\left(4x\right)}{\sin\left(2x\right)+\sin\left(4x\right)}=\tan\left(x\right)

A school survey reported that
kozerog [31]

The probability that the student has  a part-time job, given that they  have a cell phone is 5/8

<h3>What is probability</h3>

Probability is the likelihood or chance that an event will occur.

Given the following parameter:

  • Total student = 80%
  • Part-time jobs = 45%
  • Those with both a cell phone  and a part-time job = 30%

Student will cellphone only = 80 - 30 = 50%

The probability that the student has  a part-time job, given that they  have a cell phone is 50/80 = 5/8

Point M is the midpoint of AB . Through point M a line segment XY is drawn, so that both XA and YB are perpendicular to AB . Pro
GaryK [48]

Answer:

See the proof below

Step-by-step explanation:

Let the line AB be a straight line on the parallelogram.

A dissection of the line (using the perpendicular line X) gives:

AY ≅ BX

Another way will be using the angles.

The angles are equal - vertically opposite angles

Hence the line  AY ≅ BX (Proved)

John has decided to prepare an old field for his son's new horse. the length of the field is 10 meters less than 4 times its wid
tatuchka [14]

Answer: The total money invested in the field will be $1,623.80

Step-by-step explanation:

step 1

Find the dimensions of the field

Let

x -----> the length of the field

y -----> the width of the field

p=2(x+y)

p(4.80)=1,584

p=330m

we know that

The perimeter of the field is equal to

so

330=2(x+y)----> equation A

x=4y-10 ------> equation B

substitute equation B in equation A and solve for y

330=2(4y-10+y)

165=(5y-10)

5y=165+10

y+35

Find the value of x

x=4(35)-10+130

therefore

The length of the field is 130 meters and the width of the field is 35 meters

step 2

Find the area of the field

The area of the field is

A=xy

substitute

A=(130)(35)=4,550m2

step 3

Find the number of bags of seed

Divide the area by 460

4,550/460=9.89 bags

Round up to the nearest whole number

9.89 bags=10 bags

step 4

Find the cost of the seed

(10 )(3.98)=$19.8

step 5

Find the total money invested in the field

1,584+$39.8=$1,623.80
