Simplify the expression. Write your answer as a power.
(-4).(-4)
The simplified expression is
Answer:
(-4).(-4) = 4^2
Step-by-step explanation:
First, some rules that we need to remember:
if A is a positive number, then:
-A = (-1)*A
Also:
A*A = A^2
We also should remember that we can multiplicate in any order we want, this is:
A*B*C = (A*B)*C = A*(B*C)
And we also can change the order of the numbers:
A*B = B*A
And finally, we need to remember the sign rules for multiplication.
(+)*(+) = (+)
(+)*(-) = (-)
(-)*(+) = (-)
(-)*(-) = (+)
Ok, now let's look at our expression.
(-4)*(-4)
First, we can rewrite this as:
( (-1)*4)*((-1)*4)
And we can rearrange the numbers to:
(-1)*(-1)*4*4
Now let's multiplicate the first two ones, because of the sign rule, we know that the outcome will be positive, and 1 times 1 is equal to 1,
(-1)*(-1) = 1
Then:
(-1)*(-1)*4*4 = 1*4*4 = 4*4
And we know that when a number is multiplied by itself we can rewrite it as:
4*4 = 4^2
Then:
(-4).(-4) = 4^2
The simplified expression is 4^2
if a half a gallon of milk costs $1.24 then whats the cost per pint?
Answer:
Step-by-step explanation:
It costs . 31 cents for 1 pint of milk.
Answer:
1 pint would be ($1.25/4 pints) = $0.31
Step-by-step explanation:
There are eight pints in a US gallon, and thus four in half a gallon.
That comes to four pints of milk.
That's $1.24/(half gallon), or $2.48/gallon.
Since half a gallon (4 pints) is $1.25, 1 pint would be ($1.25/4 pints) = $0.31

Step-by-step explanation:
Amount of gas used to cut one lawn (on an average) = 3/4 of a tak
Given ,
In a week , ten such lawns are cut
Hence, Total amount of gas used
= 3/4* 10
= 7.5 tank

The expression (x^22) (x^7)^3 is equivalent to x^p. What is the value of p?
Answer:
x^87
Step-by-step explanation:
Multiplying x^22 and x^7 results in x^29.
Then we have:
(x^29)^3 = x^87
Recall that (a^b)^c = a^(bc) and that a^b*a^c = a^(b + c)
A quadrilateral in the coordinate plane has vertices (3, 2), (3,-4), (5,4), and (5,-2). What is the area, in square units, of the quadrilateral?

In a class, everyone studies French or German, but not both languages. One third of the girls and the same number of boys study German. Twice as many boys as girls study French. Which of the total number of boys and girls in my class
Answer:
32
Step-by-step explanation:
Let the number of girls in the class be 3. Then the number of girls who study German is , as is
the number of boys who study German. So the number of girls who study French is 2 and the
number of boys who study French is 2 × 2 = 4.
Therefore the total number of boys and girls in the class is + + 2 + 4 = 8 and hence is a
multiple of 8. Of the options, only 32 is divisible by 8.

People use water to cook, clean, and drink every day. An estimate of 15.5% of the water used each
day is for cooking. If a family uses 68.2 gallons of water a day for cooking, how many gallons do they use every day?
Answer:
260 gallons
Step-by-step explanation:
An estimate of 26.5% of the water used each day is for cleaning and a family uses 68.9 gallons of water a day for cleaning,
Percentage of water used for cleaning= 26.5%
Gallons of water used for cleaning= 68.9
Let the number of gallons used everyday be represented by g. This will give:
26.5% of g = 68.9
26.5/100 × g = 68.9
0.265 × g = 68.9
0.265g = 68.9
Divide both side by 0.265
0.265g/0.265 = 68.9/0.265
g= 260
260 gallons of water are used everyday
