Answer:

Right triangle

Step-by-step explanation:

A right triangle is a triangle in which one angle is a right angle.

Answer:

circumference = 97.34

Step-by-step explanation:

circumference = diameter x Pi

31 x 3.14 = 97.34 inches

The circumference of the circle with a diameter of 31 inches is approximately 97.34 inches.

The circumference of a circle can be calculated using the formula C = πd, where C represents the circumference and d represents the diameter of the circle.

Given that the diameter of the circle is 31 inches, we can substitute this value into the formula:

C = 3.14 * 31

C ≈ 97.34 inches

Therefore, the circumference of the circle with a diameter of 31 inches is approximately 97.34 inches.

Answer:

Step-by-step explanation:

The first triangle right isosceles. The sides opposite the 45° angles are the same length.

x = 13

By the Pythagorean Theorem, y = 13√2

:::::

Second triangle is 30°-60°-90°. Remember that the sides of a 30°-60°-90° triangle are in the ratio 1:√3:2.

The side opposite the 30° has length 3, so the side opposite the 60° angle is 3√3 and the side opposite the 90° angle is 6.

x = 6

y = 3√3

:::::

The third figure has another 30°-60°-90° triangle. The side opposite the 30° angle is 17, so the side opposite the 60° angle is 17√3 and the side opposite the 90° angle is 2×17 = 34.

x = 17√3

The other triangle is right isosceles.  

z = 34

y = 34√2

Answer:

x = 6

Step-by-step explanation:

(5x-24)/2 = 3

2.5x - 12 = 3

2.5x = 15

x = 6

Answer:

a = 17

Step-by-step explanation:

a + (-5) = 12

Open the bracket;

a - 5 = 12

Add 5 to both sides

a - 5 + 5 = 12 + 5

Therefore,

a = 17

Answer:

a=17

Step-by-step explanation:

any number plus a negative number is basically subtracting the absolute value of the negative number. so 12 + 5 = 17

Answer:

The function a^x is increasing, while a^-x is decreasing.

Answer:

x = .23

x = 1.43

Step-by-step explanation:

1. The root of a polynomial is when the y-value equals 0. So set the equation euqal to 0:

[tex]3x^{2} -5x+1=0[/tex]

2. Solve with the quadratic formula and you get:

[tex]\frac{5+\sqrt{13} }{6}[/tex] and [tex]\frac{5-\sqrt{13} }{6}[/tex] which is x = .23 and x = 1.43.

Answer:

(5, 1.5 )

Step-by-step explanation:

Given the 2 equations

5x - 4y = 19 → (1)

x + 2y = 8 → (2)

Multiplying (2) by 2 and adding to (1) will eliminate the y- term

2x + 4y = 16 → (3)

Add (1) and (3) term by term to eliminate y

7x + 0 = 35

7x = 35 ( divide both sides by 7 )

x = 5

Substitute x = 5 into either of the 2 equations and solve for y

Substituting into (2)

5 + 2y = 8 ( subtract 5 from both sides )

2y = 3 ( divide both sides by 2 )

y = 1.5

solution is (5, 1.5 )

Step-by-step explanation:

? = 180 - 150 = 30

Answer:

30°

Step-by-step explanation:

The line is 180 degrees so all you have to do is subtract 150° from 180°

You should end up with 30°

Whenever you see a straight line (IT HAS TO BE STRAIGHT), it is equal to 180°.
