Answer:
Step-by-step explanation:
The probability can be expressed as a number between 0 and 1 or a percent value between zero and 100%.
<u>Correct choice is:</u>
- D. The final number is greater than 1, which is not a valid probability.
The sum of the angles should be 180, so x+ (x+10) + (x+5) = 180. This simplifies to 3x + 15 = 180, so 3x = 165, so x=55.
Answer:
c-24
a-156
Step-by-step explanation:
a=180-24( angles on s straight line)=156
c= 24 opposite angles
Answer:
350 in²
Step-by-step explanation:
Assuming the solid likes are the design. So we see two parallelograms there.
Area of 1 parallelogram = base x height. Since we have a joint height, we will multiply the total height with the base (both have the same base length) to get the area of 1 design.
1 design = 3.5 x 2 = 7 in²
50 designs = 7 x 50 = 350 in²
Answer: he hiked 5.6 miles up the canyon.
Step-by-step explanation:
Let x represent his speed hiking uphill.
His speed running downhill was 2.8 mph greater than his speed hiking uphill. This means that his speed running downhill would be x + 2.8
Distance = speed × time
Kevin hiked up Lamb’s Canyon in 2 hours. This means that the distance covered by hiking uphill is 2 × x = 2x
He ran back downhill in 1 hour. This means that the distance covered by running downhill is 1 × (x + 2.8) =
x + 2.8
Since the distance uphill is the same as the distance downhill, then
2x = x + 2.8
2x - x = 2.8
x = 2.8
Therefore, the distance hiked up the canyon is
2x = 2 × 2.8 = 5.6 miles
