Answer:

Acute and scalene

Step-by-step explanation:

All the three interior angles of triangle are less than 90 then it is an acute triangle.

All the sides have different length then it is Scalene triangle. In Scalene triangle, all the sides have different length and so all the angles are of different

<h3>2 Answers: D) scalene, and E) acute</h3>

Explanation:

You have the right idea. The triangle is acute since all three angles are less than 90 degrees. The triangle is also scalene because all three sides are different lengths.

For a triangle to be equilateral, the three sides must be the same length. So we can rule out choice A.

We can rule out choice B since none of the angles are larger than 90 degrees. This contradicts choice E.

We can rule out choice C because we don't have exactly two sides the same length. This contradicts choice D.

We can rule out choice F because we don't have a 90 degree angle. This contradicts choice E.

The number that you are thinking of is 4. To get this answer I did the opposite of how you received your answer.
40 - 12 = 28
28 ÷ 4 = 7

A series of equal quarterly payments of $10,000 for 15 years is equivalent to what future worth amount at an interest rate of 6%
kogti [31]

Answer:

  $976,578.71

Step-by-step explanation:

We assume the deposits are made at the <em>beginning</em> of each quarter. The quarterly interest rate is 6%/4 = 1.5%. The number of quarterly payments is 15×4 = 60. The future value of an annuity due is ...

  A = P(1+r)((1+r)^n -1)/r

where r is the quarterly interest rate, n is the number of payments, and P is the payment amount.

  A = $10000(1.015)(1.015^60 -1)/.015 ≈ $976,578.71

The future value is $976,578.71.

The sum of 3 consecutive multiples of 4 is 180.
Paul [167]

9514 1404 393

Answer:

  56, 60, 64

Step-by-step explanation:

The middle of the three numbers is their average: 180/3 = 60. The other two will be 4 more or less than this.

The numbers of interest are 56, 60, 64.

_____

<em>Additional comment</em>

For "consecutive integer" problems, it is often useful to work with the average of the numbers. The average will be the middle number of an odd number of numbers (as here), or will be halfway between the two middle numbers if their number is even.

Even if you bother to write equations, it can work to do that in terms of the average value (middle number): (x -4) +(x) +(x +4) = 180 in this case.

Grant took $27.75 to the movies last friday. each ticket costs g dollars. write an expression to represent the amount of money g
Stolb23 [73]
To represent how much money Grant will have remaining after he buys 3 tickets, you would think of subtracting g, the price of one ticket 3 times.  This could be represented by subtracting  groups of g as well.

27.75 - g - g - g or $27.75 - 3g
