Answer:
b
Step-by-step explanation:
The area of a square = s² ← s is the length of the side, hence
s² = 800 ( take the square root of both sides )
s =
≈ 28.28
28.28 is between 28 and 29 → b
Answer:
<h2><u>
2 miles per hour</u></h2>
Step-by-step explanation:
Speed = Distance / Time
If we measure distance in miles and time in hour, we will get the speed in miles per hour.
Distance = 1 + 2/3 miles, which expressed as an improper fraction is 5/3 miles.
Time = 50 minutes which expressed in hours will be 50/60 or 5/6 hours.
(You can also see that 10 minutes is 1/6 of an hour, hence 50 minutes is 5/6 of an hour)
Speed = Distance / Time
= (5/3) / (5/6)
We know that dividing by "a/b" is same as multiplying by "b/a"
Hence, we have:
Speed = (5/3) * (6/5)
= (5 * 6) / (3 * 5)
= 30 / 15
= 2
Mara walks at a speed of 2 miles per hour
Y = 3x - 4.....x int can be found by subbing in 0 for y and solving for x
0 = 3x - 4
-3x = -4
x = -4/-3
x = 4/3...so the x int = (4/3,0)
y - 2/3x = 0....in y = mx + b form, the m represents the slope. So ur slope is -2/3
Answer:
114 marbles.
Step-by-step explanation:
Let the number of red marbles be r
Let the number of black marbles be b
<u>Given the following data;</u>
Total number of marbles = 120
Translating the word problem into an algebraic equation, we have;
.......equation 1
........equation 2
Substituting the value of "r" into equation 2, we have;



b = 6 marbles.
To find the number of red marbles;
From equation 1;
Substituting the value of "b" into equation 1, we have;

<em>r = 114 marbles.</em>
<em>Therefore, there are 114 red marbles in the bag. </em>
