Fiona started with 15/ 18 of a piece of pie. then she added another piece which was 13/6. how much did she have in total
PolarNik [594]

First piece of pie = 15/18

Second piece of pie = 13/6.

We need to find the total value.

In order to find the total value, we need to add both fractions.

Total value = First piece of pie + Second piece of pie.

=15/18 + 13/6.

In order to add those fractions, we need to find the common denominators.

We have denominators 18 and 6.

Common denominator of 18 and 6 is 18.

So, we need to multiply second fraction 13/6 by 3 in top and bottom to make the denominator of second fraction equals 18.

Therefore, 15/18 + 13/6 = 15/18 + 13*3/6*3

=15/18 +39/18.

=(15+39)/18.

=54/18.

Therefore, Fiona had 54/18 in total.

If m∠DEF = 117°, find the value of x
ollegr [7]

Answer:

x = 7

Step-by-step explanation:

Given:

∠DEF = 117°

∠DEG = (12x + 1)°

∠GEF = (5x - 3)°

Find:

value of x

Computation:

∠DEF = ∠DEG + ∠GEF

117° = (12x + 1)° + (5x - 3)°

117° = 17 x - 2

x = 7

Sasha is bisecting a segment. First, she places the compass on one endpoint, opens it to a width larger than half of the segment
FrozenT [24]

Answer:

A) Swing arcs on both sides to intersect the first two arcs created.

Step-by-step explanation:

Bisecting a segment is cutting a line into two equal parts with a line bisector.

The steps involved are;

  • Placing a compass on one endpoint
  • Opening the compass to a width larger than half of the segment
  • Swinging an arc on either side of the segment
  • While maintaining the same width, place the compass on the other endpoint
  • Swing arcs on both sides of the segment to intersect the first two arcs created
  • Using a ruler placed at the points of intersection of the arcs, draw the line bisector.

Sasha was now at step four.
