Answer:
6
Step-by-step explanation:
It would be 6 because on a square, all the sides have to be the same length. The length of the square is equal to the base of the parallelogram.
If the 5 scores have a mean of 8, then their total sum would be 8*5 = 40
Now if one score if added (let's call this score x), there are 6 scores and the mean changes to 9, thus:
(40 + x)/6 = 9
40 + x = 54
x = 14

Answer:
3454
Step-by-step explanation:
÷÷1/2=××/×/2223=×=×=÷
22÷3××÷÷
2÷=1=×+=××/
×$÷×=×2
2÷2÷/3=×
The statement first, and the statement second are correct because the number of dimes is 34, and the number of quarters is 66
What is a linear equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
0.1x + 0.25y = 19.9 and
x + y = 100
Let x = number of dimes
y = number of quarters
After solving the above system of equations by substitution method.
y = 66
x = 34
Thus, the statement first, and the statement second are correct because the number of dimes is 34, and the number of quarters is 66
