Answer:
16 1/7
Step-by-step explanation:
simple add
start with the fractions
5/7+3/7 = 8/7
simplify 1 1/7
add your whole numbers 15+1= 16 and the add your fraction 16+1/7= 16 1/7
Answer: 4:00 pm
Step-by-step explanation:
0.75r+0.75(3.20)=0.75(r+3.20)
So the answer is A. The product of 0.75 with the sum of r and 3.20
Since the end of the slide is 1 foot above the ground, the vertical rise of the
<span>slide is 8 - 1 = 7 feet, and since the slide rises at a 45 degree angle it will </span>
<span>have a horizontal run of 7 feet as well. Thus by Pythagoras the length of the </span>
<span>slide is sqrt(7^2 + 7^2) = sqrt(98) = 9.90 feet, which is about 10 feet.</span>
Answer:
2400 miles
Step-by-step explanation:
So the first equation is pretty straight forwards, it's in the slope-intercept form y=mx+b where m is the slope, and b is y-intercept, since as x increases by 1, the value y increases by m, which by definition is what the slope is, so m is the slope. In this context the slope is how many miles in x hours. So Space Explorer B flies 400 miles per hour. The amount of miles that Space Explorer A flies per mile can be calculated by dividing the 36400 by the 13 hours it had to travel. This gives you 2800 miles. So to find how many fewer miles Space Explorer B travels than Space Explorer A you subtract the 2 slopes. 2800 - 400 = 2400. So Space Explorer B travels 2400 fewer miles than Space Explorer A
