Answer:
the answer is d
Step-by-step explanation:
1st day : 7 × 10 = 70
5 × 7 = 35 70+ 35= 105
2nd day : 7 × 10 = 70
2 × 7 = 14 70+14 = 84
Answer:
840

<h3>
Solution:</h3>
<u>A few tips...</u>
- Pythagoras theorem can ONLY be used in right triangles.
- Usually, the longest side is the hypotenuse.
Option A:
- 6² = 5² + 4²
- => 36 = 25 + 16
- => 36 ≠ 41
The <u>side lengths</u> given are <u>not possible</u> for a right triangle.
Option B:
- 50² = 40² + 30²
- => 2500 = 1600 + 900
- => 2500 = 2500
The <u>side lengths</u> given are <u>possible</u> for a right triangle.
Option C:
- 30² = 20² + 10²
- => 900 = 400 + 100
- => 900 ≠ 500
The <u>side lengths</u> given are <u>not possible</u> for a right triangle.
Option D:
- 4² = 3² + 2²
- => 16 = 9 + 4
- => 13 ≠ 16
The <u>side lengths</u> given are <u>not possible</u> for a right triangle.
<h3>In conclusion...</h3>
Answer:
60 mintues
Step-by-step explanation:
1/6 of 60= 6
10 hours= 600 minutes
600÷6= 60 mintues
m<1=123
m<1+m<2=180 (straight line)
m<1+57=180
subtract 57 from both sides
m<1=123
