Answer 1
Answer:
For #3:
y = 1/2x, x = -18
Plug in -18 for 'x':
y = 1/2(-18)
y = -9
For #4:
y = -4x + 6, x = 1
Plug in 1 for 'x':
y = -4(1) + 6
y = -4 + 6
y = 2
y = 1/2x, x = -18
Plug in -18 for 'x':
y = 1/2(-18)
y = -9
For #4:
y = -4x + 6, x = 1
Plug in 1 for 'x':
y = -4(1) + 6
y = -4 + 6
y = 2

97.645.
The tenth digit is 6. The digit after that is 4, and it is not up to 5, so we round it down. If it was up to 5 or more we would have added 1 more to the 6 to become 7, but since it is not up to we leave the 6 that way.
97.645 ≈ 97.6 rounded to the nearest tenth.

Let the 5 integers be a,b,c,d and e (arranged in ascending order).
Since we know that the median is five, we can conclude that the value of c=5.
It's given that the mode is 1. 1<5, and has to be repeated more than once. Therefore, a and b = 1.
Now, the mean is 4. So, (1+1+5+d+e)=4
d+e=13 (d and e have to be greater than 5)
Which makes d=6 and e=7
In conclusion, the 5 integers are 1,1,5,6,7

The answer is 4 ounces. This problem just requires that you have a "feeling" of what the units are. You should know that 4 pounds is a heavy weight for a stapler: it would be difficult to handle. While inches and feet are not units of weight but of length.

The area of a triangle is found by using the formula;
A=1/2bh where A is area, b is base and h the height
substituting for given values;
12 2/5=1/2*3 1/4*h
Rewriting the values as improper fractions;
62/5=1/2*13/4*h
62/5=13/8h
h=62/5 *8/13
h=496/65
h= 7 41/65 units
