Gavyn can type 2200 words in 40 minutes. Stephen can type 3850 in 70 minutes.
Richard can type 3000 words in 50 minutes.
Who types at the fastest rate of words per minute?

Answer:

k=y/x

Step-by-step explanation:

70.4 is 22% of number 320, Option B is correct.

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

We have to find the 22% of 320

Let us convert 22% to decimalvalue by dividing with 100

22/100=0.22

Now multiply 0.22 with 320

0.22×320

we get 70.4

Hence, 70.4 is 22% of number 320.

Answer:

2

Step-by-step explanation:

cause 20 percent of 10 is 2 lol

I think the 3rd one, please let me know if I'm wrong. I don't want to give others the incorrect answer.

Step-by-step explanation:

2 x -3(x)- 1(y)- 2 x -1(z)= -5

Answer:

(-3,1,-1)............

The correctclassification for this triangle is:

obtuse, because 6² + 10² < 12²

Option C is the correct answer.

What is a triangle?

A triangle is a 2-D figure with three sides and three angles.

The sum of the angles is 180 degrees.

We can have an obtuse triangle, an acute triangle, or a right triangle.

We have,

To determine the classification of a triangle based on its sidelengths, we can use the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

In this case, we have a triangle with side lengths of 6 cm, 10 cm, and 12 cm. Checking the sum of the lengths of each pair of sides, we have:

6 + 10 = 16 > 12

6 + 12 = 18 > 10

10 + 12 = 22 > 6

Since all three pairs satisfy the triangleinequalitytheorem, the given side lengths do form a valid triangle.

Next, we can use the lawofcosines to determine the measure of the largest angle in the triangle, which will allow us to classify it.

The lawofcosines states that, for a triangle with side lengths a, b, and c, and the angle opposite c denoted as C, we have:

In this case, the sidelengths are a = 6 cm, b = 10 cm, and c = 12 cm. Substituting these values into the formula and solving for cos(C), we get:

cos(C) = (6² + 10² - 12²) / (2 x 6 x 10)

cos(C) = -1/5

Since the cosinefunction is negative for angles between 90 and 180 degrees, we know that angle C is obtuse.

Therefore,

The correctclassification for this triangle is:

obtuse, because 6² + 10² < 12²

Answer:

C

Step-by-step explanation:

use Pythagorean theorem

+ =

c is the longest side

if + > then it's acute (greater than)

if + < then it's obtuse   (less than)

if they are equal, then its a right triangle

+ =

36 + 100 = 144

136 = 144

136 < 144   obtuse
