The opposite of

Mathematics
1 answer:
blondinia [14]4 years ago
3 0

Answer:

False.

Step-by-step explanation:

Integers are numbers in this set:

{...,-3,-2,-1,0,1,2,3,...}

The opposite of a number is you just changing the sign of that number. Unless you are asking for the opposite of 0 which is just 0.

Example: The opposite of 5 is -5.

Example: The opposite of -5 is 5.

So the opposite of an integer does not always mean the result will be negative. As you seen above, it could be 0, positive, or negative.

Final Answer: b = -3

Steps/Reasons/Explanation:

Question: Solve for b. -9 b = 27. b = ?

<u>Step 1</u>: Divide both sides by -9.

b = -\frac{27}{9}

<u>Step 2</u>: Simplify \frac{27}{9} to 3.

b = -3

The perimeter of a rectangular garden is 110ft. The length is 5 ft greater than the width. Find the length and width.
tigry1 [53]

P = perimeter

L = length

W = width

Formula for the perimeter of a rectangle = L + L + W + W  or  P = 2L + 2W

You know:

P = 110ft

L = W + 5  [length is 5ft greater than the width]

So plug this into the formula:

P = 2L + 2W             Substitute/plug in (W + 5) for L

110 = 2(W + 5) + 2W           Distribute/multiply 2 into (W + 5)

110 = (2)W + (2)5 + 2W

110 = 2W + 10 + 2W       Combine like terms (2W + 2W)

110 = 4W + 10       Subtract 10 on both sides

110 - 10 = 4W + 10 - 10

100 = 4W     Divide 4 on both sides to get "W" by itself

\frac{100}{4}=\frac{4W}{4}

25 = W        Now that you know the width, plug it into the equation for length

L = W + 5       Plug in 25 for W

L = 25 + 5

L = 30

L = 30 ft

W = 25 ft

PROOF

P = 2L + 2W

110 = 2(30) + 2(25)

110 = 60 + 50

110 = 110

Figure 1 is a square pyramid. Figure 2 is a right triangular prism.
amm1812

Answer:

the answer is

The surface area of Figure 1 is <u>10.2</u> square centimeters <u>Less</u> than the surface area of Figure 2.

Step-by-step explanation:

Figure 1

area of a square = s2

=9squared

=81 sq cm

area of triangle = 1/2 bh

=1/2 (9cm) (14cm)

=63 sq. cm

find surface area

SA = 81 sq. cm + 4(63 sq. cm)

SA = 81 sq. cm + 252 sq. cm

SA = 333 sq. cm

Figure 2 Calculation

area of rectangle = lw

a = (12cm) (8 cm)

a = 96 sq. cm

area of triangle = 1/2 bh

=1/2 (8 cm) (6.9 cm)

= 27.6 sq. cm

total surface are of figure 2

SA = 3 (96 sq.cm) + 2 (27.6 sq. cm)

SA = 288 sq. cm + 55.2 sq. cm

SA = 343.2 sq. cm

find the difference between figure 1 and figure 2

343.2 sq. cm - 333 sq. cm = 10.2 sq. cm
