Answer:
1.5 ft
Step-by-step explanation:
Use the Pythagorean theorem and rearrange it to find the third length.
3.6^2 + x^2 = 3.9^2
3.9^2 - 3.6^2 = x^2
15.21 - 12.96 = 2.25
sqrt 2.25 = 1.5
x = 1.5
I believe that it is <u><em>$6.21</em></u>...
Hope this helps...
Answer:
- ∠BCE = 28°
- ∠ABE = 62°
- ∠BAD = 56°
Step-by-step explanation:
The diagonals of a rhombus bisect each other at right angles, and bisect each of the vertex angles. Of course, adjacent vertex angles are supplementary.
Assuming E is where the diagonals cross, then we have ...
∠ABE = 124°/2 = 62°
∠BCE = 90° -62° = 28°
∠BAD = 2·28° = 56° . . . (= 180° -124°)
Repeating decimal means that the numbers after the decimal point are repeating constantly such as 8.3333333.....and so on. Or a number that repeats a pattern forever.
So <span>15.24 </span>is <u>NOT</u> a repeating decimal because after the decimal point the number 24 is not repeating.
This would make the number a repeating decimal - 15.24242424242424242424...
Bruce has a rope that is 21 feet long he needs to cut the rope into 1/5 long pieces.
The length of the rope = 21 feet
the length of each strip =
We need to cut the rope 21 feet into strips
To find the number of strips we divide 21 feet by the length of the strip
= = 105
105 strips can Bruce cut from his rope.
