what is the smallest of three consecutive integers i the sum of the smaller two integers is two more than seven times the larges

NNADVOKAT [17]

Answer:

The numbers that meet these conditions are -3, -2 and -1.

This means that the wording of the question is somewhat ambiguous:

The lowest of the three numbers is -3.

The smallest however is -1.

You may need clarification on which of those is being asked for.

Step-by-step explanation:

Let's call those numbers a, b and c, with a the smallest and c the largest. We're told two key things here:

1) The sum of the smaller two integers is two more than seven times the largest integer. In other words a + b = 7c + 2

2) We're looking for three consecutive integers, which means that we can define them with a single variable. If the smallest one is a, then the others are a + 1 and a + 2.

We can take those and put them together, giving us the equation:

a + (a + 1) = 7(a + 2) + 2

Which we can then solve for a:

a + (a + 1) = 7(a + 2) + 2

2a + 1 = 7a + 14 + 2

2a - 7a = 14 + 2 - 1

-5a = 15

a = -3

Since a is -3 and also the smallest, we can then say that the numbers are -3, -2 and -1.

Find the distance between the points with polar coordinates (3, 120°) and (0.5, 49°)

nikklg [1K]

X 1 = 3 * cos 120° = - 3 cos 60° = - 3/2 = - 1.5
y 1 = 3 * sin 120° = 3 sin 60° = 3√3 / 2 = 2.598
x 2 = 0.5 * cos 49° = 0.328
y 2 = 0.5 * sin 49° = 0.37735479
--------------------------------------------
d = [( x 2 - x 1 )² + ( y 2 - y 1 )²]^(1/2)
d = [ ( 0.328 + 1.5 )² + ( 0.37735479 - 2.598) ] ^(1/2)
d = ( 3.341584 +4.931265 )^(1/2)
Answer: The distance is :
d = 2.876256

Maya wrote the expression 3+5+4.5 to represent the total distance that she traveled. Which statement best describes Maya’s expre

harina [27]

Answer:

The statement, Maya’s expression will generate the correct sum because of the associative property will describe the best.

Solution:

Maya’s expression will generate the correct sum because of the associative property.

Maya wrote the expression $3+5+4.5$

As per commutative property of addition if we change the order still the sum will be same, which means $(a + b) = (b + a)$

Here also, $(3 + 5) + 4.5 = 8+4.5 = 12.5$

Again $3 + (5+4.5) = 3+9.5 = 12.5$

As both the results are same, hence this is meeting the commutative property of addition.
