my friend needs help with this can someone help

Answer:

Option A and option B applies

Step-by-step explanation:

The compound interest formula is given by:

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

Marcus has opened a savings account where the yearly interest rate is 10%. He deposits $1,000 to start the account.

This means, respectively, that: [tex]r = 0.1, P = 1000[/tex]. So

[tex]A(t) = 1000(1 + \frac{0.1}{n})^{nt}[/tex]

Option A:

[tex]n = 1[/tex]. So

[tex]A(t) = 1000(1 + \frac{0.1}{1})^{t}[/tex]

[tex]A(t) = 1000(1.1)^{t}[/tex]

So option A applies

Option B:

[tex]n = 12[/tex]. So

[tex]A(t) = 1000(1 + \frac{0.1}{12})^{12t}[/tex]

0.1/12 = 0.008. So

[tex]A(t) = 1000(1 + 0.008)^{12t}[/tex]

[tex]A(t) = 1000(1.008)^{12t}[/tex]

So option B also applies.

The other options will not apply.

Answer and Step-by-step explanation:

First, read through the phrase and then break it down.

4 less than the product (multiplying) of 7 and a number (can be noted as 'x')

7x - 4 is the answer, since 4 will be less than the product of 7 and a number, with x being the placeholder.

Step-by-step explanation:

Answer: (x)^2 + (y)^2 = 90,000

Step-by-step explanation: we know that

The equation of the circle (the roof of the Colosseum) in standard form is equal to (x-h)^2 + (y-k)^2 =r^2

where

(h,k) is the center and r is the radius

we have

(h,k)=(0,0) ----> is the origin

----> the radius is half the diameter

substitute

Answer: 35

Step-by-step explanation: i first divided 12 and 125 since there is 125 cards in total and 12 different cards which gives you 10 point something. There is 3 multiples of 4 so i multiplied 3x10 which gives you 30 and the closest answer is 35. You're welcome

Answer:

[tex]\frac{5}{4}[/tex]

Step-by-step explanation:

we can find the zero of the linear function

F(x)= -4x+5 ,by solving the equation -4x+5 = 0

Solving the equation:

-4x+5 = 0

⇔ -4x = -5

[tex]\Longleftrightarrow x=\frac{-5}{-4} =\frac{5}{4}[/tex]

⇔ x = 1.25

Answer:

x < -8.5

Step-by-step explanation:

[tex]-46-8x>22[/tex]

add 46 to both sides

[tex]-8x >68[/tex]

divide both sides by -8

[tex]x < -8.5[/tex]

Answer:

a is your correct answer

Answer:

6

Step-by-step explanation:

Answer:

11,000 paid $14 for reserved seats.

25,000 paid $6 for general admission.

Step-by-step explanation:

First, we need to establish the system of equations:

x= number of people that pay $14

y= number of people that pay $6

14*x + 6*y= $304,000

x + y= 36,000

Now, we isolate x in one equation and substitute it in the other one:

x= 36,000 - y

14*(36,000 - y) + 6y = 304,000

504,000 - 8y = 304,000

200,000 = 8y

25,000 = y

x= 36,000 - 25,000

x= 11,000

11,000 paid $14 for reserved seats.

25,000 paid $6 for general admission.

Add the ratios: 5 + 4 = 9

Divide total students by 9:

27/9 =3

Girls are listed first so the 5 part of the ratio is girls.

Multiply 5 by the 3 from above:

5 x 3 = 15

There are 15 girls.

Answer:

There are 12 girls in the classroom because if you take 4+4+4=12 and you do the same with 5 so 5+5+5=15 then add them together you get 27. So, therefore, your answer would be 12

Answer:

Your answer is 3x = 15

Step-by-step explanation:

3x = 15

Since 3 is being multiplied by x, we divide both sides by 3.  3x/3 cancels out, and you're left with x.

15/3 = 5

x = 5

This is my take using algebraic methods.

Answer:

63 in^2

Step-by-step explanation:

Area = base x height

Base: 7

Height: 9

9 x 7 = 63

Answer:

63 inches squared or [tex]63in^{2}[/tex]

Step-by-step explanation:

The answer is 63 inches squared.

The area of a parallelogram is always base times height.

In this case, the base is seven and the height is nine.

To find the area, we must multiply nine by seven

We get 63

But, we are multiplying inches and inches together

When we multiply something by itself, it becomes squared

Since we are multiplying inches by inches, it becomes inches squared

Therefore, the area of the shape is 63 inches squared, or

[tex]63in^2[/tex]

Answer:the perimeter of the rectangle =A) (−14w+14v) centimeters

Step-by-step explanation:

Step 1

The perimeter of a Rectangle is given as 2 (l+ w)

If Length = 2v+3w centimeters.

and width =5v-10wcentimeters

Then Perimeter =2 (2v+3w + 5v-10w)

Perimeter=2(7v -7w)

Perimeter= 14v - 14w or can be written as -14w +14v

1h----------------> 70x3=210 bacteria

2h-----------------> 210*3=630 bactaeria

let be y the number of bacteria at the t=0h

it is y=70 3^0

for t= 1h

y=70*3^1=210

for t=2h

y=70*3^2=630

so we can write y=70*3^x, where x is the number of hour

Answer:

2 1/4 pints

Step-by-step explanation:

create a ratio with the fact there are 16 ounces in 1 cup

let 'p' = number of pints

16 = 36

 1         p

cross-multiply:  16p = 36

                            p = 36/ 16, which is 9/ 4, or 2 1/4
