Iteru [2.4K]
<span>There are 5 boxes, where we have to put given numbers. Addition of 5 odd numbers always gives an odd number result. 30 is an even number. So there is no combination of given numbers which can give you 30 as a result.

Show all work please will give brainliest answer❕❗️❕❗️❕❗️❕❗️❕David drops a ball from a bridge at an initial height of 100 meters
Inessa [10]
First, 9.8 (Gravity) times 3 (time) equals 29.4, which is the velocity after 3 seconds. The kinematic equation for change in position that uses the variables we have is:
delta x= (v)(t) -0.5(acceleration)(time)^2
delta x= 29.4 times (3) - 0.5 (9.8) times 9
delta x= 44.1
100 minus 44.1 equals 55.9, which is the answer for part a.

Tell me if you need any clarification

PART B:
The kinematic equation for this is:
delta x= (initial velocity) times time plus 0.5 (a)(time)^2
100=(0)times(x) plus 0.5 (a)(time)^2
100=0.5(9.8)(x)^2
100=4.9x^2
100/4.9 is approxamitely 20.4.
The squareroot of this is approxamitely 4.5.

What is the value of 5 in 756
BartSMP [9]
7: has a value of 7 hundreds (or 700)
5: has a value of 5 tens (or 50)
6: has a value of 6 ones (or 6)

5 has a value of 50 or five tens

I believe you would draw this by drawing something that looks like place value blocks. I have attached an example of that. In the ones column, you will have 6 single blocks

How do you do this question?
tatyana61 [14]

Answer:

25

Step-by-step explanation:

The increments are 0.4, and the width of the interval is 10, so the number of increments (the number of times you need to use Euler's method) is:

10 / 0.4 = 25
