Write a fraction that is less than 5/6 and has a denominator of 8
KatRina [158]
You'll want to make a common denominator with 6 and 8.
That denominator would be 24.
24/6=4 so you would have to multiply 5/6 by 4/4 to get 20/24.
Next, 24/8=3 so 1/8 could be multiplied by 3/3 to get 3/24.
Since 3 is less than 20, 1/8 is smaller than 5/6.

If you want the same numerator, 5/8 = 15/24. This would make 5/8 smaller than 5/6 as well.
The highest eighth you can go is 6/8 which is 18/24.
So you can use any numerator between 1 and 6 with a denominator of 8 to get a fraction smaller than 5/6.

Please answer i will give brainlest! SHOW WORK!!!!
Dahasolnce [82]

The new dimensions or scale according to the information provided is now 4m/2units. See the explanation below.

<h3>What is the explanation justifying the above answer?</h3>

According to the given graph, the perimeter is 12 units. The current scale is 48m to 12 units (or 4m to 1 unit). Hence the new scale will be twice the original graph.

That is:

2m/1 units = (2m x2)/ 1unit x 2

= 4m/2units.

See the attached and enlarged new image.

Section II

The dimensions of the picture are as follows:

Length: acm

Width: bcm

Thus,

Length ⇒ acm/lft = lcm/5ft

L = (5a)ft

Width: ⇒ bcm/wft = Lcm/5ft

w = (56) ft

Another picture:

Length: 5a/8 cm

Width: 5b/8 cm

What is sin 45°? O A. 1/2 12 1 OB. NI O C. 1 O D. O E. 1 3 O F. 13 ap.ex​
andrew-mc [135]

1/√2

Step-by-step explanation:

Imagine a right-angled triangle, for e.g. Triangle ABC,

Where

B = 90°

Remember your Toa Cah Soh.

sin 45° = opposite / hypotenuse

If theta = 45°

Angles A and C = 45° (Sum of angles in a triangle equal = 180°)

Since theta are the same, we can also deduce that the length AB and BC are the same.

Take for example AB = BC = 1 = opposite

By the Pythagorean theorem,

AB² + BC² = AC²

1² + 1² = AC²

2 = AC²

AC = √2 = hypotenuse

Therefore:

sin 45° = opposite / hypotenuse

sin 45° = 1/√2
