Answer:
Step-by-step explanation:
To calculate the speed of each one we proceed as follows:
speed=distance/time
a] Noah's speed:
distance=2.5 miles
time=3/5 hours
speed=(2 1/2)/(3/5)
=(5/2)/(3/5)
=5/2×5/3
=25/6
=4 1/6 mi/hr
Emily's speed
distance=3 3/4 miles
time=5/6 hour
thus
speed=(3 3/4)/(5/6)
=15/4)/(5/6)
=15/4×6/5
=4 1/2 mi/hr
Anna's speed:
distance=3 1/3 miles
time=3/5
speed=(3 1/3)/(3/5
=(10/3)/(3/5)
=10/3×5/3
=5 5/9 mi/hr
Anna was the fastest

hello
Step-by-step explanation:
1- slope is 4 y intercept 0,2
2- slope is 6 y intercept 0,5
3- slope is 2 y intercept is 0,5
4 -slope is 1 y intercept is 0, 3/4
5- slope is 10 y intercept is 0,3
6- slope is 4 y intercept is 0,1/2
7- slope is 4 y intercept is 0, 3/2
8- slope is 1 y intercept is 0,2
The probability is 3/5. Since there are 5 out of 10 sections labeled with an even number, the denominator of the desired probability is 5. Since t<span>hree sections are both colored red and labeled with an even number, the numerator is 3. The probability is 3/5. We can also use conditional probability: P(A|B)=P(AUB)/P(B). Let A=section colored red, B=section labeled with even number. P(AUB)=3/10, while P(B) is 1/2, so P(A|B)=3/5.

For Q1 add 135 and 45 together. If it comes out to be 180 which it does the angles are supplementary. In Q2 add 23 and 67 together and if it comes out to 90 it is complementary, but if it doesn't it is neither. In Q3 take 3x+45=180 subtract 45 on both sides so you get 3x=135 then divide by 3 to get X. Your answer should be 45. For Q4 look that exact question up and find a good answer for it. Hope this could help
