7300-5500=1800 needs to come from salespeople. To make at least 7300, the salespeople need to make at least 1800, which means:
300 x number of people >= 1800
Number of people >= 6
C is correct

Answer:

at + vi = vf

Step-by-step explanation:

In order to solve for vf, we need to isolate said variable.

a = vf - vi/t (Given)

at = vf - vi (Multiply t on both sides)

at + vi = vf (Add vi on both sides)

A group of hikers walks 3 miles east and then 1 mile north. After taking a break, they then hike 4 miles east to their final des

geniusboy [140]

Answer:

The vector that describes their hike from their starting position to their final destination is $\vec r = 7\,\hat{i}+1\,\hat{j}\,\,\,[mi]$ .

Step-by-step explanation:

In this problem we assume that orthogonal axes coincide with the north and east. We proceed to translate each sentence from statement into vectorial equations:

(i) <em>A group of hikers walks 3 miles east and then 1 mile north:</em>

$\vec r_{A} = 3\,\hat{i}+1\,\hat{j}\,\,\,[mi]$

(ii) <em>After taking a break, they then hike 4 miles east to their final destination:</em>

$\vec r_{B} = 4\,\hat{i}\,\,\,[mi]$

The vector that describes their hike from their starting position to their final destination is the sum of the vectors deducted above. That is:

$\vec r = \vec r_{A}+\vec r_{B}$ (1)

$\vec r = (3\,\hat{i}+1\,\hat{j})+4\,\hat{i}\,\,\,[mi]$

$\vec r = 7\,\hat{i}+1\,\hat{j}\,\,\,[mi]$

The vector that describes their hike from their starting position to their final destination is $\vec r = 7\,\hat{i}+1\,\hat{j}\,\,\,[mi]$ .

Which statement can be combined with its converse to form a true biconditional?

andrey2020 [161]

Answer:

I couldn't read C. It contained words like rat, raid devices?

Step-by-step explanation:

The converse of p->q is q->q.

So let's look at each choice:

A) The converse of

"if the measure of an angle is 30, then it is an acute angle"

is:

"If is is an acute angle, then the measure is 30"

The converse is not true so the biconditional will not be true. There are other angles beside 30 that are acute.

B) The converse of

"if two lines intersect, then the two lines are not skew"

is:

"If the two lines are not skew, then the two lines intersect"

The converse is false because if it isn't skewed, then they could still be parallel and parallel lines don't intersect.

D) The converse of

"if an angle is a straight angle, then it’s sides are opposite rays.:

is:

"If the angle's sides are opposite rays, then it's angle is straight"

True.

So the biconditional is

"an angle is straight, if and only if, the angle's sides are opposite rays.

Legs: The two ________ sides of a right triangle; the sides that meet at ___ degrees.

Dmitrij [34]

Hello there!

Legs: The two smaller sides of a right triangle; the sides that meet at 90°.

In Pythagorean Theorem, all three sides of a right triangle have names and certain measurements that explain their names. The legs of a right triangle are the two smaller sides; they meet at a 90° angle and form a square to ensure the 90°. The bigger side of a right triangle is what we call the hypotenuse. The hypotenuse equals what the legs squared add up to. For example, we can take the three measurements:

12 cm, 5 cm, 13 cm

Since the two smaller numbers are 5 and 12, those would be our legs in the right triangle. Because 13 is the largest, it would be our hypotenuse. To identify the equivalence of the equation, we would square 5 and 12 to see if it equals up to 13 squared

5 squared is 25, and 12 squared is 144. Because 144 + 25 = 169, and 13 squared is 169, we know that the right triangle exists. If you need a further explanation, let me know and I will gladly assist you.
