Noah has 75 marbles. Noah has more marbles. this is because 34 times 3 is equal to 102. since michelle takes 9 marbles from EACH box, 9 times 3 is 27. 102 minus 27 is 75
Answer:
<u></u>
- <u>She should aim 6 feet down the wall</u>
Explanation:
The diagram attached sketches the situtation.
Since the angle with which the ball hits the wall is the same with which it bounces, angle β is the same for the two shown triangles.
Then, since both are right triangles, then all the angles are congruent and the triangles are similar. Hence, you can equal the ratios of the sides, to make an equation:
You have other equation:
Substitute
- 2y + y = 18
- 3y = 18
- y = 18/3
- y = 6 ← this is the distance down the wall where the ball should hit
Then, she should aim 6 feet down the wall.
Answer:
K=13,5
y=13,5x, x=numbers of hours
Step-by-step explanation:
To find the proporcionality constant, divide the number of milles traveled in given time.
K=54/4=67,5/5=81/6=13.5 and the equation that describes the relationship is y=13,5x
To complete the table, just use the given equation to solve for the corresponding values of y. and i think the formula is wrong, it should be
y = <span>25,000 • 0.95^x</span>
at x = 1
<span>a0 = y = 25,000 • 0.95^x
</span>a0 = <span>25,000 • 0.95^(1)
a0 = 23750.00
at x = 2
a1 = </span>y = <span>25,000 • 0.95^x
a1 </span>= <span>25,000 • 0.95^( 2 )
a1 = 22562.50
at x = 3
a2 = </span>y = <span>25,000 • 0.95^x
a2 = </span> <span>25,000 • 0.95^( 3 )
a2 = 21434.38
</span>
