Answer:

Every Rational number when multiply by 0.5 produces a rational number.

Step-by-step explanation:

Rational Number is a number that can be changed in the formation of \frac{p}{q}, where p & q are real numbers and q ≠ 0.

Even a natural number can also be a rational number since it can be change into \frac{number}{1}

So, the every rational number when multiply by 0.5 produces a rational number. For example: 2 × 0.5 = 1 (rational number)

7 × 0.5 = 3.5 (rational number)

42.63 × 0.5 = 21.315 (rational number)

But, \sqrt{2}\times0.5 = irrational as it has non terminating decimal number (also \sqrt{2} is irrational number)

Solve algebraically 16 = 64 - 32t
GaryK [48]

Answer:

t= 3/2 (i think this is what you meant?)

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

16=64−32t

16=64+−32t

16=−32t+64

Step 2: Flip the equation.

−32t+64=16

Step 3: Subtract 64 from both sides.

−32t+64−64=16−64

−32t=−48

Step 4: Divide both sides by -32

CAN SOMEONE PLS HELP ILL GIVE YOU BRAINLIST!! I DONT UNDERSTAND IT .
Harman [31]

Answer:

m∠P = 82°

m∠Q = 49°

m∠R = 49°

Step-by-step explanation:

<em>In the isosceles triangle, the base angles are equal in measures</em>

In Δ PQR

∵ PQ = PR

∴ Δ PQR is an isosceles triangle

∵ ∠Q and ∠R are the base angles

→ By using the fact above

∴ m∠Q = m∠R

∵ m∠Q = (3x + 25)°

∵ m∠R = (2x + 33)°

→ Equate them

∴ 3x + 25 = 2x + 33

→ Subtract 2x from both sides

∵ 3x - 2x + 25 = 2x - 2x + 33

∴ x + 25 = 33

→ Subtract 25 from both sides

∵ x + 25 - 25 = 33 - 25

∴ x = 8

→ Substitute the value of x in the measures of angles Q and R

∵ m∠Q = 3(8) + 25 = 24 + 25

∴ m∠Q = 49°

∵ m∠R = 2(8) + 33 = 16 + 33

∴ m∠R = 49°

∵ The sum of the measures of the interior angles of a Δ is 180°

∴ m∠P + m∠Q + m∠R = 180°

→ Substitute the measures of angles Q and R

∵ m∠P + 49 + 49 = 180

∴ m∠P + 98 = 180

→ Subtract 98 from both sides

∵ m∠P + 98 - 98 = 180 - 98

∴ m∠P = 82°

The formula for the volume of a tetrahedron is given as v=sh. Rewrite the
IrinaK [193]

Answer:

h = 6 units

Step-by-step explanation:

The formula for the volume of a tetrahedron is given as :

V = sh

Where

s is area of base and h is height

Put s = 8 and V = 48 to find h as follows :

h=\dfrac{V}{s}\\\\=\dfrac{48}{8}\\\\h=6

So, the height of the tetrahedron is 6 units.
