Step-by-step explanation:
(this probably won't help so sorry) this is how I would do it:
6x+24 =90
90-24=66
6x= 66
66/6 =11
x=11
Answer:
6.875° C
the mean of a set of data is calculated using
mean =
For the first 7 days the mean is 8 and the count = 7
8 = ( cross- multiply )
sum = 8 × 7 = 56
Add on the temperature on the 8 th day to the sum and divide by 8 for mean
sum = 56 - 1 = 55
mean = = 6.875° C
2nd question
Height of marble from the ground
An independent variable is the variable in an experiment that you change to see if it has an effect on the dependent variable. In this case, Jack wanted to see whether the position of the marble on the ramp (which would be the height) has an effect on the kinetic and potential energy of the marble, then the height would be the independent because it is what is being changed.
The dependent would be the kinetic and potential energy and the constant would be the type of marble.

there you go now can you help me???????...
Answer:
I think it would be 13 feet
Step-by-step explanation:
12*5=60
and sense it is a triangle you divide by 2 and get 30
<h3>30-12-5=13</h3><h3>this is what I think</h3>
Answer:
v = 0
Step-by-step explanation:
12 = 12 + v / 8
0 = 1/8v
v = 0
