Answer:
n+12 <4
Step-by-step explanation:
Answer:
A. 0
B. -66
C. 4
D. 998
E. -12
Step-by-step explanation:
A. By definition, the sum of anything and its additive inverse is zero.
__
B. If you have trouble with sums, your calculator can help.
-22 + (-44) = -22 -44 = -66
__
C. -36/x = -9 can be solved by multiplying by x and dividing by -9:
-36 = -9x
-36/-9 = x = 4
Since the product of the divisor and quotient is the dividend, dividing the dividend by either gives the other. Here, your dividend is -36 and your quotient is -9. To find the divisor, you can divide -36 by -9, as we did.
__
D. The absolute value function changes the sign of negative numbers to positive:
|-998| = 998

E. If you have trouble with sums, your calculator can help.
(−2)−[(−3)−(−7)−(−6)]
= -2 -(-3 +7 +6) = -2 -10 = -12
<u>Statement</u><u>:</u>
The circle has a diameter of 16 inches.
<u>To </u><u>find </u><u>out:</u>
The area of the circle.
<u>Solution</u><u>:</u>
- Diameter of the circle = 16 inches.
- Radius of the circle
- = Diameter ÷ 2
- = 16 inches ÷ 2
- = 8 inches
- We know, area of a circle = πr² where r is the radius.
- Therefore, the area of the circle
- = 3.14 × (8)² square inches
- = 3.14 × 64 square inches
- = 200.96 square inches
- = 201 square inches [rounded to the nearest square inch]
<u>Answer</u><u>:</u>
C) 201 square inches

The scientific notation is a method that scientists use
to easily handle very large numbers or very small numbers. As an example,
instead of writing down the value 0.0000000065, we write the value 6.5 x 10-9
in scientific notation. The number of places the decimal point got moved
becomes the exponent of the number 10. When the movement is from left to right,
the exponent is negative (for very small numbers). When it is right to left,
the exponent is positive (for very large numbers).
Therefore writing estimated measurements in scientific
notation:
length of a grain of salt : 0.0002 centimeters = 2 x 10-4
centimeters
width of a key ring : 0.02 centimeters = 2 x 10-2
centimeters
