Answer:

The TV would cost $1,080.

Step-by-step explanation:

The discount would be $120. So $1,200 - $120 = $1,080.

Answer:

Step-by-step explanation:

$24.5

Answer:

We can use a trick here. Let's look at the first few exponents of i to realize this:

i^0 = 1

i^1 = i

i^2= -1

i^3 = -i

i^4 = 1

i^5 = i

i^6 = -1

i^7 = -i

we can see that the pattern (1, i, -1, -i) repeats. Since 82/2 = 41, and 41 is only divisible by 1, i^41 = i, and i^2 = -1. -1*i = -i, so i^82 = -i.

Step-by-step explanation:

The proportional equation that represents the situation is k=2/3.

Given that, Jacqui needs 8 cups of sugar to make 12 batches of cookies.

We need to find what is the proportional equation that represents the situation.

Proportion, in general, is referred to as a part, share, or number considered in comparative relation to a whole. The proportion definition says that when two ratios are equivalent, they are in proportion. It is an equation or statement used to depict that two ratios or fractions are equal.

Based on the type of relationship two or more quantities share, the proportion can be classified into different types. There are two types of proportions.

The number of cups of sugar used to make batches of cookies is a direct proportion.

8∝12

⇒8=12k

⇒k=8/12

⇒k=2/3

Therefore, the proportional equation that represents the situation is k=2/3.

Answer:

76 and 100

Step-by-step explanation:

We solve this question busing Empirical rule.

Empirical rule states that:

68% of data falls within 1 standard deviations from the mean - between μ – σ and μ + σ

From the above question,

Mean = 88

Standard deviation = 12

Hence,

μ - σ

= 88 - 12

= 76

μ + σ

= 88 + 12

= 100

The two values that 68% of the data falls withing is 76 and 100

Answer:

The number of pounds of apples that are needed to make

1 pie = 3.5 pounds of Apples

2 pies = 7 pounds of Apples

3 pies = 10.5 pounds of Apples

Step-by-step explanation:

The double number line shows that to make 4 apple pies takes 14 pounds of apples.Select the double number line that correctly labels the number of pounds of apples that are needed to make 1 , 2, and 3 pies.

Hence;

For 1 pie

4 apple pies = 14 pounds of apples

1 apple pie = x pounds

4 apple pies × x pounds = 1 apple pie × 14 pounds of apples

x pounds = 1 apple pie × 14 pounds of apples/4 apple pie

x pounds = 3.5 pounds of apples

For 2 pies

4 apple pies = 14 pounds of apples

2 apple pies = x pounds

4 apple pies × x pounds = 2 apple pies × 14 pounds of apples

x pounds = 2 apple pies × 14 pounds of apples/4 apple pie

x pounds = 7 pounds of apples

For 3 pies

4 apple pies = 14 pounds of apples

3 apple pies = x pounds

4 apple pies × x pounds = 3 apple pies × 14 pounds of apples

x pounds = 3 apple pies × 14 pounds of apples/4 apple pie

x pounds = 10.5 pounds of apples

Answer:

Miranda made 9 visits to the store and Savannah made 7 visits to the store

Step-by-step explanation:

To find how many times Miranda and Savannah went to the store we would need to find the Greatest Common Multiple of the amount that each of them spends per visit. We do this by simply going through each of these numbers' times tables until we find a common one.

7 * 1 =  7                     9 * 1 = 9

7 * 2 =  14                   9 * 2 = 18

7 * 3 =  21                   9 * 3 = 27

7 * 4 =  28                  9 * 4 = 36

7 * 5 =  35                  9 * 5 = 45

7 * 6 =  42                  9 * 6 = 54

7 * 7 =  49                  9 * 7 = 63

7 * 8 =  56                  

7 * 9 =  63      

Finally, we can see that the first time that both Miranda and Savannah have spent the exact same amount would be when Miranda made 9 visits to the store and Savannah made 7 visits to the store. Each of which wasted $63

Answer:

Step-by-step explanation:

Step one:;

given data

start time= 7:00 am

end time= 9:00 am

we are told that one broadcast shows commercial every 17minutes

and the other shows commercials every 14 minutes

now the time when they both sho commercial is given by the greates common multiple of the times 17 and 14

multiples of  17= 17,34,51,68,85,102,119,136,153,170,187,204,221,238

multiples of  14= 14,28,42,56,70,84,98,112,126,140,154,168,182,196,210,224,238

for the number above 238 is common to both

238minutes to hours= 3.96667

=3:58 minutes

this shows that commercials will show at the same time 1:58 minutes after the show

Answer:

The amounts invested in the account = ¢ 18000

and the amount invested in the stock = ¢40000-¢18000= ¢22000.

Step-by-step explanation:

Given that the account paying 4% interest and the stocks paying 6% interest.

Assuming she put ¢ x in the account, so

Income (interest) from the account = 4% of x = ¢ 0.04x...(i)

She has a total of ¢ 40000 to invest, so the remaining amount = ¢(40000-x).

As she put the remaining amount into stock, so

Income (interest) from the stock=6% of (40000-x)=¢(2400-0.06x)...(ii)

As total income from the investment is ¢ 2040, so on adding both the incomes from equations (i) and (ii), we have

[tex]2040=0.04x + (2400-0.06x) \\\\\Rightarrow 2040=2400 - 0.02x \\\\\Rightarrow 0.02x = 2400-2040=360 \\\\\Rightarrow x = 360/0.02=18000.[/tex]

So, the amount invested in the account = ¢ 18000

and the amount invested in the stock = ¢40000-¢18000= ¢22000.

Answer:

Please check the explanation!

Step-by-step explanation:

Given the equation

[tex]f\left(x\right)=-2|x+1|-1[/tex]

As some of the absolute rules are:

NOW, let us solve!

Let us substitute all the table values

Putting x = -4

[tex]y=-2\left|-4+1\right|-1[/tex]        ∵[tex]\mathrm{Apply\:absolute\:rule}:\quad \left|a\right|=a,\:a\ge 0[/tex]

[tex]y=-6-1[/tex]

[tex]y=-7[/tex]

So, when x = -4, then y = -7

Putting x = -3

[tex]y=-2|-3+1|-1\:[/tex]

[tex]y=-4-1[/tex]

[tex]y=-5[/tex]

when x = -3, then y = -5

Putting x = -2

[tex]y=-2\left|-2+1\right|-1[/tex]

[tex]y=-2-1[/tex]

[tex]y=-3[/tex]

when x = -2, then y = -3

Putting x = -1

[tex]y=-2\left|-1+1\right|-1[/tex]

[tex]y=-0-1[/tex]

[tex]y=-1[/tex]

when x = -1, then y = -1

Putting x = 0

[tex]y=-2\left|0+1\right|-1[/tex]

[tex]y=-2-1[/tex]

[tex]y=-3[/tex]

when x = 0, then y = -3

Putting x = 1

[tex]y=-2\left|1+1\right|-1[/tex]

[tex]y=-4-1[/tex]

[tex]y=-5[/tex]

when x = 1, then y = -5

Answer:

g(5) = 375

Step-by-step explanation:

g(x) = 3x³

g(5) = 3(5)³

g(5) = 3(125)

g(5) = 375

The required value of g(5) is 375. which is determined by substituting the value of x = 5 in the function of g(x).

The function is defined as a mathematical expression that defines a relationship between one variable and another variable.

The functions are given in the question,

f(x) = 2x² - 5x, g(x) = 3x³

We have to determine the value of g(5).

⇒ g(x) = 3x³

Substitute the value of x = 5 in the function of g(x) and then evaluate

⇒ g(x) = 3x³

⇒ g(5) = 3(5)³

Here (5)³ = 5 × 5 × 5 = 125

⇒ g(5) = 3(125)

Apply the multiplication, and we get

⇒ g(5) = 375

Therefore, the required value of g(5) is 375.

Answer:

1. A number having 2, 3, 7 or 8 at unit's place is never a perfect square. In other words, no square number ends in 2, 3, 7 or 8. The number of zeros at the end of a perfect square is always even. In other words, a number ending in an odd number of zeros is never a perfect square.

2. Only those numbers, when squared will have 6 at their unit place are 4 and 6 Because 4×4 = 16 and 6×6 = 36(i dont know if this is what you were looking for)
