what is the value of x

Answer:

A = 49 ft^2

Step-by-step explanation:

The perimeter of a square is given by

P = 4s where s is the side length

28 = 4s

Divide each side by 4

28/4 = 4s/4

7 =s

We want the area

A = s^2

A = 7^2

A = 49 ft^2

Answer:

A

Step-by-step explanation:

The Fundamental theorem of algebra tells us that a polynomial of degree n has n roots.

Here the polynomial is a cubic, that is of degree 3

Thus it will have 3 roots, real and/ or imaginary.

Since imaginary roots occur in conjugate pairs

Since the polynomial has 3 real roots there are no imaginary roots, thus

A is the required response.

Answer:

The largest possible result she can get is 550

Step-by-step explanation:

Here we have that to find the largest possible result, the numbers from which the last number is subtracted from should be the largest possible, hence

Whereby, we had K × A × N + G × A - R × O × O, then;

K ------- 9

A---------8

N---------7

G---------6

A---------8

R---------2

O---------1

O---------1

will give, 504 + 48 - 2 = 550

If however, the A = 7 and N = 8 we have;

504 + 42 - 2 = 544

Hence, the largest possible result she can get = 550.

This question is difficult to give a definite answer to because it's an approximation, but I estimate the solutions to be around x = 2.6 and x = -2.6.

When they ask for solutions of the graphed function they are asking for an approximation of where the graph intercepts the x-axis, and we can see it kind of intercepts in the middle of 2 and 3, except slightly closer to 3, which is why I estimated 2.6.

The graph also appears to be symmetrical, which means the solutions will be the same except one would be negative and one would be positive, which means the second solution would be -2.6.

I hope this helps! Let me know if you have any questions :)

Answer:

The electrician charges an initial fee of $42

Step-by-step explanation:

Answer:

In this case we can propose a rule of three:

$ 18 ---------------> 100%

x --------------------> 25%

Where x represents the discount made to the pillow:

So we have the new price (with the discount) is:

In addition, if 25% is discounted we have to, the price of the pillow is 75% of the original price. That is to say:

Step-by-step explanation:

Answer :

a= $4.50

b= $13.50

Step by step explanation: 1- find 25% of 18 which is 4.50. 2- subtract 18-4.50= 13.50

Step-by-step explanation:

Answer:

a, c

Step-by-step explanation:

Let's start with one of each choice. That'll be 3 * 4 * 3 * 3 * 10 = 1080 pizzas. As for the second one, this time the toppings won't be 10 it will be 10 * 9 * 8 because we have 10, and then 9, and then 8 topping choices. This gives us 1080 * 9 * 8 = 77,760. Hope this helps!

Answer:

Step-by-step explanation:

Well, we can multiply the choices that they gave us, which is 3 by 4 by 3 by 3 by 10, which will give 1080 for the first part. Now, if you was to do only 3 toppings, it should be 3 by 4 by 3 by 3 by 3, which would give us 324. I don't know if this is right but I think this is the right answer.

Answer: 3.4

Step-by-step explanation:

V=4/3•pi•(r)^3

164.636=4/3•pi•(r)^3

164.636/(4/3•pi)= 39.3…

39.3=(r)^3

*cubed root of both sides* r=3.399… so r=3.4

Answer:

Step-by-step explanation:

The Salsa jar has a cylindrical shape. We would determine the volume of Salsa that the jar normally contains and the volume left in the jar by applying the formula for determining the volume of a cylinder which is expressed as

Volume = πr²h

Where

r = radius

π = 3.14

For normal volume,

h = 10 cm

r = 5 cm

Volume = π × 5 × 10 = 50π cm³

For volume left,

h = 4cm

Volume = π × 5 × 4 = 20πcm³

Missing volume = 50πcm³ - 20πcm³ = 30π cm³ = 30 × 3.14 = 94.2 cm³

Answer:

Jeep value after six years is $11,327.9

Step-by-step explanation:

To find the value of depreciation, we use the exponential function below;

V = I(1-r)^t

where V is the future value of the Jeep which we are to calculate

I is the initial value of the jeep which is $28,000

r is the rate of decrease or depreciation which is 14% or simply 14/100 = 0.14

t is time which is 6 years

Plugging these values into the equation, we have;

V = 28,000(1-0.14)^6

V =28,000(0.86)^6

V = 11,327.88

To the nearest cent; V = $11,327.9

Answer:

The 96th term of the given AP is (-1048)

Step-by-step explanation:

We have, the given AP is :

-3, -14, -25....

First term is -3

Common difference is -14 - (-3)= -11

Let [tex]a_{96}[/tex] is the 96th term of the AP.

The nth term of the AP is given by :

[tex]a_n=a+(n-1)d[/tex]

Put all the values, such that,

[tex]a_{96}=(-3)+(96-1)\times (-11)\\\\a_{96}=-1048[/tex]

So, the 96th term of the given AP is (-1048).

Answer:

5c+2

Step-by-step explanation:

Not sure the steps

The formula for Douglas' winning percentage is 5c + 2.

The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.

Given, Douglas and Jesse play video games together. Douglas won two more than five times the number of games that Jesse won.

Since "c" represents the number of games Jesse won

Number of games Douglas won = 5c + 2

Therefore, an expression for the number of games Douglas won is 5c + 2.

Answer:

c and d

Step-by-step explanation:

4/8 = 1/2

a.1/2 =1/2 so it is not greater

b.1/4  <  1/2 = 2/4  so 4/8 is greater

c.7/8   > 4/8  so 7/8 is greater

d.3/5     3/5 = 6/10    1/2 = 5/10

                     3/5 >     4/8

Answer: 7/8 and 3/5

Step-by-step explanation:

First, let’s look at 4/8 and 1/2. They have different denominations so let’s change them. 2 and 8’s closest multiple that they share is 8. 8/8=1, so we have to multiply the numerator and denominator by 1 which doesn’t change the fraction. 8/2=4, so we have to multiply the numerator and denominator by 4 which makes it: 4/8. 4/8 and 4/8 are the same so they are equal.

Next, let’s look at 4/8 and 1/4. They have different denominations so let’s change them. 4 and 8’s closest multiple that they share is 8. 8/8=1, so we have to multiply the numerator and denominator by 1 which doesn’t change the fraction. 8/4=2, so we have to multiply the numerator and denominator by 2 which makes it: 2/8. 4/8 is greater than 2/8 so this would be a wrong answer.

Then, let’s look at 4/8 and 7/8. They have the same denominations so we don’t have to change them. Let’s look at the numerators though: 4 and 7. 7 is greater than 4 so this answer would be correct.

Finally, let’s look at 4/8 and 3/5. They have different denominations so let’s change them. 5 and 8’s closest multiple that they share is 40. 40/8=5, so we have to multiply the numerator and denominator by 5 which makes it 20/40. 40/5=8, so we have to multiply the numerator and denominator by 8 which makes it: 24/40. 24/40 is greater than 20/40, so this answer is correct.

Hope this helps!
