Answer:

Option A. Yes; the sum of each pair is greater than the third.

Step-by-step explanation:

As we know triangle inequality theorem clearly states that a triangle is possible only when sum of two sides of the triangle is greater than third side of the triangle.

The given sides of the triangle are 20m, 22m and 24m.

so by theorem of inequality

22 + 20 > 24

42 > 24

Therefore, answer will be (A) sum of each pair is greater than third.

The correct answer is A) yes, the sum of each pair is greater than the third.

The triangle inequality theorem states that the sum of any two sides of a triangle is longer than the third side. This is true for these numbers, so this does form a triangle.

Which gives the correct values for points A, B, C, and D?
saveliy_v [14]

Answer:

<em>The correct answer is: A</em>

Step-by-step explanation:

<u>Points on a Numeric Line</u>

The numeric line shown in the figure has four points A, B, C, and D. It's clear that each marked division of the line has a value of 1/4 units and all four points are below the reference zero, thus all are negative.

Point A is clearly on the -2 mark, thus

A=-2

Point B is one mark above A, thus it's located at:

B=-2+\frac{1}{4}=-\frac{7}{4}=-1\frac{3}{4}

B=-1\frac{3}{4}

Point C is one mark below -1, thus:

C=-1-\frac{1}{4}=-1\frac{1}{4}

Finally, point D is one mark below 0:

D=-\frac{1}{4}

The correct answer is: A

Which statements about 12 ÷ 7 are true? Use the array to answer the question. Check all that apply.
AURORKA [14]

Answer:

The remainder is 5

Step-by-step explanation:

12 Divided by 7 equals 12 over 7 or 1.714285. 7 can only go into 12, one time. if we subtract 7 from 12 we get 5 which is the remainder. There is no way it can be 2 because 7 plus 2 equals 9. 1 x 7 + 5 equals 12 which isn't 1.714285. 2 x 7 + 4 equals 18 which also isn't 1.714285. Same with 2 x 5 + 5. That equals 15 which isn't 1.714285.

I need someone really good at math to help me please!! A home is purchased for $394,000 with a 14% down payment. Find the monthl
julia-pushkina [17]

9514 1404 393

Answer:

  $2300.01

Step-by-step explanation:

The down payment is 14% of $394,000, so is ...

  0.14 × $394,000 = $55,160

This means the principal amount of the loan is ...

  $394,000 -55,160 = $338,840

__

The amount of the monthly loan payment is given by the amortization formula ...

  A = P(r/12)/(1 -(1 +r/12)^(-12t))

where P is the principal amount, r is the annual interest rate, and t is the number of years. Filling in the values, we have ...

  A = $338,840(0.072/12)/(1 -(1 +0.072/12)^(-12·30))

  = $338,840(0.006)/(1 -(1.006^-360)) = $2300.01

The monthly payment is $2300.01.
