Answer:
44 degrees.
Step-by-step explanation:
Since angle A is 46 degrees, and angle C is 90 degrees (because of the right angle) you add 46 and 90 (you get 136) then subtract it from 180 (since every triangle equals 180 degrees) which gets you to 44 degrees.
Answer:
64
Step-by-step explanation:
To find m, it has given you √x = 8. The opposite of a square root is squaring (exponentials). Simply just square 8 and you should get x = 64. You can check by square rooting 64, and you should get 8.
Answer:
A 2 ounce bag costs $1.2.
Step-by-step explanation:
With the information provided, you can use a role of three to find the cost of a 2 ounce bag given that you know that a six ounce bag costs $3.60.
6 ounce bag → 3.60
2 ounce bag → x
x=(2*3.60)/6
x=7.20/6
x=1.2
According to this, the answer is that a 2 ounce bag costs $1.2.
The expression (−81)(−9) will give the value of 729.
<u>Step-by-step explanation:</u>
The given expression is (−81)(−9)
.
The both numbers in the expression are negative numbers and they are given inside the brackets.
This means that, the negative numbers must be multiplied to get a final value.
<u>The rules in multiplication are :</u>
- Positive number × Positive number = positive number
- Negative number × Positive number = negative number
- Positive number × Negative number = negative number
- Negative number × Negative number = positive number
From the rules, it can be determined that the result of any two negative numbers will be a positive number.
So, eliminate option A) and B) because they have negative sign.
The expression (−81)(−9) = -81 × -9
⇒ 729.
Therefore, the option C) and D) are not in match with 729. None of the options are not the value of the given expression (−81)(−9).
