The model of the bridge and the actual bridge are similar solids. The lengths of corresponding sides of similar figures are in proportion.
5/25 = 6/30 = 8/40 = 1/5
Answer: 1/5
X+20/2
X/2+10 is the answer
Answer:
<em>The complement is 47° and the supplement is 137°.</em>
Step-by-step explanation:
<u>Complementary and Supplementary Angles</u>
When the sum of two angles is equal to 90 degrees, they are called complementary angles. Similarly, if the sum of two angles is 180 degrees, they are called supplementary angles.
We are given an angle of 43 degrees. Its complementary angle is 90° - 43° = 47°, and its supplementary angle is 180° - 43° = 137°.
The complement is 47° and the supplement is 137°.
<span>A. 8 wreaths, 6 trees, 2 sleighs
Nothing much to do for this problem except to try each option and see if it meets the constraints of available time. So let's check them out.
A. 8 wreaths, 6 trees, 2 sleighs
prep = 8 * 3 + 6 * 14 + 2 * 4 = 116 hours.
paint = 8 * 2 + 6 * 3 + 2 * 15 = 64 hours.
fire = 8 * 9 + 6 * 4 + 2 * 7 = 110 hours.
All three values are less than or equal to the constraints of 116, 64, and 110.
This option will work.
B. 6 wreaths, 2 trees, 8 sleighs
prep = 6 * 3 + 2 * 14 + 8 * 4 = 78 hours.
paint = 6 * 2 + 2 * 3 + 8 * 15 = 138 hours.
138 is more than the allowed 64, can't do this option.
Don't bother to calculate how many hours of firing needed.
C. 9 wreaths, 7 trees, 3 sleighs
prep = 9 * 3 + 7 * 14 + 3 * 4 = 137 hours.
137 is more than the allowed 116, can't do this option.
Don't bother to calculate how many hours of painting or firing needed.
D. 2 wreaths, 8 trees, 6 sleighs
prep = 2 * 3 + 8 * 14 + 6 * 4 = 142 hours.
142 is more than the allowed 116, can't do this option.
Don't bother to calculate how many hours of painting or firing needed.
Of the 4 choices available, only option "A" falls under the required time constraints.</span>
If it’s 67.8 repeating then just put a bar on top of the .8 .
