Answer:

n=−5

Step-by-step explanation:

n−4−3n=3n+6−3n

−2n−4=6

Step 2: Add 4 to both sides.

−2n−4+4=6+4

−2n=10

Step 3: Divide both sides by -2.

−2n /−2 =  10 /−2

n=−5

Answer:

Rate = 10%

Step-by-step explanation:

We are given with the following details.

Interest earned = $ 116.25

Principal = $ 1550

Interest Rate = r (say)

Time = 9 months

         = \frac{9}{12} years

We are asked to determine the rate of interest for which we can earn 116.25 interest. As we are not specifically given whether it is a compound or simple interest , we assume it to be simple interest and solve .

The formula for simple interest is given as

Interest = Principal \times Rate \times time

116.25=1550 \times r \times \frac{9}{12}

r= \frac{116.25 \times 12}{1550 \times 9}

r=0.1

Hence the r = 0.1

Hence the rate of interest is 10%

Which function produces an output of 5 for an input of -6?
kodGreya [7K]

Answer:

The answer is D

Step-by-step explanation:

Since the input is -6, you input it into the equation. That would make it f(-6)=-(-6)-1 which would be equivalent to f(-6)=6-1 , as the negatives at the beginning of the equation cancel each other out and make it positive. Then you solve and get 5, which is your output. Hope I could help :)

If you reverse the first two letters
Na
Fe
Hg
Sn

They are actually symbols for elements
Na - Sodium
Fe - Iron
Hg - Mercury
Sn - Tin

Since Sn is a symbol for Tin and each pair of letters imply the starting letter of the element they are symbolizing, the answer is

What is the area of this trapezoid?
liberstina [14]

Answer:

7.5\:\text{square units}

Step-by-step explanation:

The area of a trapezoid is given by the average of the bases multiplied by the height.

What we're given:

  • Height of 3
  • Bases of 1 and 4

The average of the bases 1 and 4 is equal to \frac{4+1}{2}=\frac{5}{2}=2.5

Therefore, the area of the trapezoid is 2.5\cdot 3=\boxed{7.5\:\text{square units}}

We are given with height= 9 ft. Length=10 ft. Wall Brackets: 48-inch cost $12.95 68-inch cost $16.95 Distance from brackets from
VikaD [51]

Answer:

$89.7

Step-by-step explanation:

We are given with

height = 9 feet

length = 10 feet

wall brackets:

48-in costing $12.95

60-in costing $16.95

distance of brackets from ends = 1 foot

maximum distance between brackets= 24 inches

The brackets are

48/12 = 4 feet

and

60/12 = 5 feet

One of each must be used to cover the height of the shelf

The length of the shelf is

60 inch

subtracting 1 in from each side for the allowance

60 - 2 = 58 in

Dividing by 24 inches

58/24 = 2.41 ~ 3 

The total cost is

($12.95 + $16.95) * 3 = $89.7

The total cost of the brackets is $89.7
