Answer:

<h2>B. 72 + 78 + 70 + x > 289</h2>

Step-by-step explanation:

To solve this problem, you just have to remember that "at leat" means a least value, that is, John must have 289 or more points to pass the exam. Therefore is he has > 289, he definitely will pass.

So, the right expression must include the sum of all scores with a > sign.

The exact expression would be

72+78+70>289

Therefore, the right answer is B.

The recursive formula to describe a sequence is shown below, state the first 4 terms.
djyliett [7]

Answer:

The terms are {81, 27, 9, 3}

Step-by-step explanation:

A recursive formula uses the previous number in a sequence to find the new number. The given formula just divides the previous term by 3.

So:

Term 1: 81

Term 2: 81/3 = 27

Term 3: 27/3 = 9

Term 4: 9/3 = 3

PLEASE HELP, PLEASE....
inysia [295]

Answer:

allen= y=3/2+2  billy= y= 3/2+4

Step-by-step explanation:

ok both of the equation are (almost) the same except for the y intercepts.

y=mx+b... you are learning about that hopefully!

so. each of their trees are growing by 3... feet I'll just say feet. that means the slope is three because they are each going up that much. you also have to pay attention to the fact that the year is going up by two, so your tree is actually growing by 1.5 (3 halves) feet each year. now you have to find the y intercept by back tracking. remember that the y intercept is where y is zero and x is whatever it is.

if you go back three on allen, the y intercept is 2 and if you go back on billy, the y intercept is 4.

as for the second question, the lines are parallel. they have the exact same slope so that means that they will never cross  because billy's line is higher then allens, billy's tree will always be higher

Julia needs to make a box in the shape of a rectangular prism with a height of 3 inches and a volume of 243 cubic inches. The di
umka2103 [35]
The volume of a rectangular prism is equal to length*width*height. In this case, we have V = 243 and H = 3.
243 = LW(3), so LW = 81, where L & W are whole numbers greater than 1. There are only 3 possible pairs of values for this: 27*3, 9*9, and 3*27 (we cannot use 1*81 or 81*1, since we need dimensions > 1).
Part A. This could be true if Length = 9 in and Width = 9 in, as 9*9 = 81.
Part B. The claim could be false if Length = 27 in and Width = 3 in, as 27*3 = 81, but 27 is not equal to 3.
*Note that the width cannot be longer than the length.
