Answer:
6
Step-by-step explanation:
No. objects in one set = 7
Let there be n set
Then, No. objects in n set = 7*n = 7n
Given that total no of objects are 48
Thus,
7n = 48
n = 48/7 = (42+6)/7 = 42/7 + 6/7 = 6 + 6/7
n = 6 + 6/7
Thus, there will be 6 set which has 7 objects. fraction means one set is fraction 6/7 but set cannot be in fraction hence negating it.
Now, total objects in 6 sets = 6*7 = 42.
No. of objects left = 48 - 6 = 6
Answer:
A
Step-by-step explanation:
Taking the square root of both sides, you get
which simplifies to
The square root of 180 is approximately 13.42 and since it is the plus or minus square root, the answer is A, -13.42, 13.42.
Answer:
The value of the investment by the end of the month is $59.89.
Percent loss = 20% to the nearest tenth
Step-by-step explanation:
At the end of the month, there was a loss of $13.53 from the $73.42 investment at the beginning of the month.
Value in Dollars = $73.42 - $13.53
= $59.89
The value of the investment by the end of the month is $59.89.
PERCENTAGE LOSS =
(CP - SP / CP ) * 100
= ($73.42 - $59.89 / $73.42) * 100
= ($13.53 / $73.42) * 100
= 0.184 * 100
= 18.43%
= 20% to the nearest tenth

- b) Midpoint is (2, 6)
===================
<h3 /><h3>Given</h3>
- Points A( - 1, 10) and B(5, 2)
<h3>To find</h3>
- a) The length of AB
- b) The midpoint of AB
<h3>Solution</h3>
a) Use the distance formula:
Substitute the coordinates and calculate:
The distance is AB = 10 units
b) Use midpoint formula and find x and y- coordinates of this point:
and 
Substitute coordinates and find the midpoint:
and 
The midpoint is (2, 6)
