What number is to be multiplied with 1/3 to get 1/21

dybincka [34]

Answer:

1/7

Step-by-step explanation:

Since we do not know the number let us use the alphabet A to represent the unknown number

A × 1/3= 1/21

A/3= 1/21

Cross multiply both sides

A×21= 3×1

21A= 3

Divide both sides by the coefficient of A which is 21

21A/21=3/21

A=1/7

Hence the unknown number is 1/7

The measure of length SV is 60 units

<h3>Isosceles Right Triangle</h3>

An Isosceles right triangle is a right triangle that has equal opposite and adjacent sides.

The above means that:

$SV = ST$

Substitute values for SV and ST

$2z = z + 30$

Subtract z from both sides

$z = 30$

From the figure, we have:

$SV = 2z$

Substitute 30 for z

$SV = 2 \times 30$

$SV = 60$

Hence, the measure of length SV is 60 units
