Can 31/50 be simplified

Answers

no because when one number is odd and the other one is even it can't be simplified (unless they are multiples/factors of each other) ex: 7/14

No, 31, a prime number, can not be divided any more to become another numerator, not to mention having to correspond with 50 as well.

Bonsoir à tous, j'ai besoin d'aide urgemment en maths si possible et merci d'avance. L'exercice est photographié ci-dessus

Answers

m<SAB = 180 - 58,5 = 121,5

180 - 121,5 - 34,1 = 23,4

(sin 121,5)/SB = (sin 23.4)/18,7

SB = (sin 121,5 * 18,7)/(sin 23,4)

SB = 40,15

sin B = h/SB

h = (SB) * sin B

h = 40,15 * sin 35.1

h = 23,1

42 less than the product of 28 and an unknown number is 154

Answers

42 less than (-42) the product of (multiply) 28 (28) and an unknown number (x) is (=) 154
28 times x-24=154
pemdas
multiplication
28 times x=28x
28x-42=154
add 42 to both sides
28x+42-42=154+42
28x=196
divide both sides by 28
x=7
the number is 7

28X-42=154
+42 +42
-----------------
28X = 196

Quadrilateral WXYZ is inscribed in a circle with m∠W = 50° and m∠X = 108°. What is m∠Z?

Question 2: Quadrilateral WXYZ is inscribed in a circle with m∠W = 50° and m∠X = 108°.

What is m∠Y?

Answers

Answer:

For Question 1

$\angle Z =72$ °

For Question 2

$\angle Y =130$ °

Step-by-step explanation:

Given

$\angle X =108$ °

$\angle W =50$ °

For a Quadrilateral inscribed in a circle we have opposite angles are Supplementary that is

For question 1

$\angle X + \angle Z = 180\n108 + \angle Z =180\n\angle Z =180-108=72$

For question 2

$\angle W + \angle Y = 180\n50 + \angle Y =180\n\angle Y =180-50=130$

Answer:

1. 72

2. 130

How to solve 8=3/4w on math

Answers

When you have to divide by a fraction, you have to multiply the other number by the fraction's reciprocal.

8 = 3/4 w Divide by 3/4

w = 8/(3/4)

w = 8/ (3/4) = 8 x 4/3 Multiply by the numerator and divide by the denominator.

w = (8 x 4) / 3

w = 32 / 3

w = 10 2/3

You want to isolate the variable w so you want it by itself. To do so with a fraction multiply both sides by the fraction's denominator...
8(4)=3w
32=3w
Now you want to divide both sides by 3
32/3=w
10.67=w
This should be your answer :)
