round off 45682 in two significant figure​

Answers

Answer:

Rounded it's 46,000

Step-by-step explanation:

The answer is 46000.


Explanation:

In “45682”

‘5’ is the second significant figure.

While rounding off, we have to check the number behind the one chosen, in this case 5 is chosen. So we will look at the one behind 5 which is 6.

As 6 is larger than 5, we will round up.


The answer is 46000



Brief notes:

If the number is smaller than 5, we round down,

If the number is larger than 5, we round up.

If the number is equal to 5, we still round up.

Rewrite the polynomial in the form ax^2+bx+cax 2 +bx+c and then identify the values of a,a, b,b, and cc. -x+5x^2+1

Answers

Given:

The polynomial is

[tex]-x+5x^2+1[/tex]

To find:

The polynomial in the form [tex]ax^2+bx+c[/tex] and find the values of a, b and c.

Solution:

We have,

[tex]-x+5x^2+1[/tex]

Arranging the terms in descending order of their degrees, we get

[tex]=5x^2-x+1[/tex]

[tex]=(5)x^2+(-1)x+1[/tex]

On comparing this polynomial with [tex]ax^2+bx+c[/tex], we get

[tex]a=5,b=-1,c=1[/tex]

Therefore, the value of a is 5, the value of b is -1 and the value of c is 1.

A triangle has sides with lengths of 7 meters, 10 meters and 13 meters is it a right triangle

Answers

Answer:

No

Step-by-step explanation:

7 squared + 10 squared = 149

13 squared = 169

As you can see these two products are not equal. They have to be equal to be a right triangle.

So this triangle is not a right triangle.

Hope that helped you and have a great day!

Answer:

No it is not.

Step-by-step explanation:

Let h = 13, p = 10 and b =7

Using pythagoras theorem,

h² = p² + b²

13² = 10² + 7²

169 = 100 + 49

169 = 149

This is false so the triangle is not a right angled triangle.

Answers

Answer:

Step-by-step explanation:

11). 6x + 3y = 9

    3(2x + y) = 9

    2x + y = 3

    y = -2x + 3

    Since variables are of single degree therefore, it's a linear function

12). 3y - 2x = -2x - 12

     3y - 2x + 2x = -2x - 12 + 2x

     3y = -12

      y = -4

     Since variable y is of single degree therefore its a linear function.

13). 11y + 4x = -8 + 11y

     11y + 4x - 11y = -8 + 11y - 11y

     4x = -8

      x = -2

      Linear function.

14). 4x - 3 + 2y = 8x - 9

     4x + 2y - 3 - 4x = 8x - 4x - 9

     2y - 3 = 4x - 9

     2y = 4x - 9 + 3

     2y = 4x - 6    

      y = 2x - 3

      Linear function.

Answers

Answer:

  a) $15,779.70

  b) $13,679.70

  c) $210.92

Step-by-step explanation:

a) When tax is added, the total cost is ...

  total = price × (1 +tax rate)

  total = $14,775 × 1.068 = $15,779.70

__

b) The amount financed is the difference between the total cost and the down payment.

  financed = total - down35

  financed = $15,779.70 -2100 = $13,679.70

__

c) The monthly payment is found using the amortization formula. It can also be found using any of a number of financial calculators, spreadsheets, or apps.

  A = P(r/12)/(1 -(1 +r/12)^-n) . . . . annual rate r, n monthly payments, principal P

  A = $13,679.70(0.035/12)/(1 -(1 +0.035/12)^-72) ≈ $210.92

Henry and his children went into a grocery store and where they sell peaches for $2 each and mangos for $1.25 each. Henry has $20 to spend and must buy no less than 10 peaches and mangos altogether. If Henry decided to buy 4 peaches, determine all possible values for the number of mangos that he could buy. Your answer should be a comma separated list of values. If there are no possible solutions, submit an empty answer.

Answers

Since 4 peaches x 2 =8, you would would only be able to buy 6 mangos since $1.25 x 6 mangos =$7.5 so it would be $7.5+$8=$15.5 and 6 mangos+4 peaches=10 in total. And he would also save $5.00! :)

Hannah is putting in a tile floor. She needs to determine the angles that should be cut in the tiles to fit the corner. The angle in the corner measures 90. One piece of the tile will have a measure of 38. Write an equation, and use it to determine the measure of the unknown angle.

Answers

Answer:

180=90+38+x

where x equals missing angle

x=52

Step-by-step explanation:

Hello There!

remember the sum of the interior angles of a triangle is 180

so to find the measure of the missing angle we subtract the given angles from 180

180-90-38=52

so the measure of the missing angle is 52

Arthur is organising his collection of dvds he has 135 altogether. The ratio of comedy films to action horror is 6 : 8 : 1

Answers

Answer: See explanation

Step-by-step explanation:

The number of comedy films will be:

= 6/(6+8+1) × 135

= 6/15 × 135

= 54 comedy films

The number of action films will be:

= 8/(6+8+1) × 135

= 8/15 × 135

= 72 action films

The number of horror films will be:

= 1/(6+8+1) × 135

= 1/15 × 135

= 9 horror films
