Ahmed spent 2/3 of his money on a burrito and a water. The burrito coast 2 times as much as the water. The burrito cost $4, how much money does Ahmed have left?

Answers

The burrito costs twice as much as water. Let's assume the water costs $w
$4=2w
w=$2 
Ahmed spent $2+$4=$6
2/3 of the total amount = $6
Total amount =$6x3/2
                      =$9
if a burritto is twice as much as water the the water is two dollars. if Ahmed spent 2/3 of his money then( 4+2=6) for burrito and water it means he had nine dollars originally so he is left with 3 dollars.

11.Can 90 degree, 90degree and 20 degree form a triangle? *1 pointyesnosometimesnone of these​

Answers

Final answer:

Angles of a triangle always add up to 180 degrees. The given angles (90, 90, 20 degrees) give a total of 200 degrees, hence they cannot form a triangle.

Explanation:

In order for three angles to form a triangle, they must satisfy the triangle inequality theorem, which states that the sum of the measures of any two angles in a triangle must be greater than the measure of the third angle.

In this case, you have angles measuring 90 degrees, 90 degrees, and 20 degrees. Let's apply the theorem:

1. Angle 1: 90 degrees

2. Angle 2: 90 degrees

3. Angle 3: 20 degrees

Now, let's check if these angles satisfy the triangle inequality theorem:

- Angle 1 + Angle 2 = 90 degrees + 90 degrees = 180 degrees

- Angle 3 = 20 degrees

According to the theorem, the sum of any two angles must be greater than the measure of the third angle. However, in this case, the sum of Angle 1 and Angle 2 (180 degrees) is not greater than Angle 3 (20 degrees). Therefore, these angles do not satisfy the triangle inequality theorem.

So, the answer is "no," 90 degrees, 90 degrees, and 20 degrees cannot form a triangle because they do not satisfy the triangle inequality theorem.

Answer:

no. never.

Step-by-step explanation:

total internal angles of a triangle sum to 180. 90 + 90 is 180 so no, you cannot have a triangle with sides 90 90 and 20. it is possiblw to have 90 45 and 45 though

Find the value of A in the equation 5/a+3=3/A-2

Answers

If you would like to find the value of a in the equation 5/a + 3 = 3/a - 2, you can do this using the following steps:

5/a + 3 = 3/a - 2     /*a
5 + 3a = 3 - 2a
3a + 2a = 3 - 5
5a = -2
a = -2/5

The correct result would be -2/5.
5+3a = 3-2a
So
5a = -2
a=-2/5=-0.4

Suppose you walk 18.5 m straight east and then 22.5 m straight north. How far are you from your starting point in m)? וח What is the compass direction of a line connecting your starting point to you

Answers

Final answer:

The distance from the starting point is approximately 29.14 meters and the compass direction of the line connecting the starting point to the end point is approximately 50.03° east of north.

Explanation:

To find the distance from the starting point, we can use the Pythagorean theorem which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the two legs. In this case, the two legs of the triangle represent the distances walked in the east and north directions. So, the distance from the starting point is:




Distance = sqrt((18.5)^2 + (22.5)^2)


Distance = sqrt(342.25 + 506.25)


Distance = sqrt(848.50)


Distance ≈ 29.14 meters



To determine the compass direction of the line connecting the starting point to the end point, we can use trigonometry. We can find the angle of this line with respect to the east direction using the tangent function:




Angle = arctan(22.5/18.5)


Angle ≈ 50.03°



Therefore, the distance from the starting point is approximately 29.14 meters and the compass direction of the line connecting the starting point to the end point is approximately 50.03° east of north.
