Fred says that 1/2 and 7/8 are equivalent fractions. Draw area models for 1/2 and 7/8 to show if Fred's statement is correct. Na
jok3333 [9.3K]

Answer:

For your area models you would draw two rectangles and divide one into 2 equal sections, and the other one with 8 equal sections. You then shade 1 box out of the first triangle with 2 equal sides. Then you would shade 7 boxes on the rectangle with 8 equal sides. These diagrams would show you that 7/8 and 1/2 are not equivalent.

To find out what fractions are equivalent to 1/2 you would take 1/2 and times the numerator and denominator by the same number.

1/2*2/2= 2/4

2/4=1/2

1/2*9/9= 9/18

9/18=1/2

2/4 and 9/18 both equal 1/2

Hope this helps ;)

Find the value of the lettered angles in each of the following ( see image ).
Arisa [49]

Step-by-step explanation:

here's the solution :-

1.) =》f = 90°

( because angle made by diameter on circumference of the circle measures 90° )

2.) =》here,

g + f + 56° = 180°

( because the sum of all interior angles of the triangle measures 180° )

=》g + 90° + 56° = 180°

=》g + 146° = 180°

=》g = 180° - 146°

=》g = 34°

3.) h = 56°

( since, they form alternate interior pair which are equal )

A sequence of 7 numbers starts with 8. The second number in the sequence is unknown and may be positive or negative. The third t
scoray [572]

Answer:

4

Explanation:

a_1=8,a_7=0

Since the third term is the sum of the two previous terms

a_3=a_2+a_1

a_7=a_6+a_5

a_7=a_5+a_4+a_4+a_3

Continuing in like manner

a_7=5a_3+3a_2

Since a_3=a_2+a_1

a_7=5(a_2+a_1+3a_2

a_7=5a_2+5a_1+3a_2

a_7=8a_2+5a_1

Recall: a_1=8,a_7=0

0=8a_2+5*8

8a_2=-40

a_2=-5

The sequence is therefore:

8,-5,3,-2,1,-1,0

The sum of the seven numbers is 4.
