The answer is D because all the rest of the statments are untrue. d is also right because 4 people walked 3-5 miles and 3 people walked 6-8 miles and as you know, 3+4=7
Answer:
20√3 cm
Step-by-step explanation:
Altitude of an equilateral triangle splits it into 2 equal right triangles, it bisects the base and the angle opposite to the base.
<u>Let the altitude be x. Then as per Pythagorean theorem:</u>
- x² = 40² - (40/2)²
- x²= 1600 -400
- x²= 1200
- x= √1200
- x= 20√3 cm
<u>Correct choice is</u> the second one
Turn both fractions into mixed fractions resulting in 75/2 and 5/2. Then turn them into decimals. 75/2= 37.5 and 5/2= 2.5. Then divide each other 37.5 / 2.5= 15. 15 is your answer. Hope it helped :)
Just had this question. The answer is 40
3 X (8x+5)
Answer:
3x + 100 < 2x - 250
Step-by-step explanation:
The problem said that Keisha's guess was "250 less than twice the number".
It was written as 250-2x, which is actually twice the number less than 250, because we are subtracting 2x. We just need to write it like this:
2x-250
So the inequality should be:
3x + 100 < 2x - 250
