Answer:

You have 16 quarts and 28 nickels lol

Step-by-step explanation:

Answer:

16 quarters and 28 nickels

Step-by-step explanation:

Because...

1 quarter=25 cents of so if you have 16 quarters that=4.00$

2 if there are 12 more nickels then there are 28 nickels.

1 nickle=5 cents. so what is 28 x 5=1.40$

Then add 4.00$+1.40$=5.40$ and there is your answer.

Hope this helps have a great day:)

Answer:

82 cm^2

Step-by-step explanation:

First, find the formulas for the areas of all of the shapes shown

area of rectangles = base * height

area of triangle = 1/2 * base * height

for the triangle at the top, area = 1/2 * 5 * 2 = 5 cm^2

for the bottom triangle, area = 1/2 * 5 * 2 = 5 cm^2

for the left rectangle, area = 6 * 3 = 18 cm^2

for the middle rectangle, area = 5 * 6 = 30 cm^2

for the right triangle, area = 4 * 6 = 24 cm^2

add all of these together

5 + 5 + 18 + 30 + 24 = 82 cm ^2

We are provided , Tomas learned that a³ + b³ = (a + b ) ( a² - ab + b² ) , and his teacher writes four products on the board and we have to tell that which product suits the best if a = 2x and b = y

Now , putting a = 2x , b = y in the given formula we have :

[tex]{:\implies \quad \sf (2x)^{3}+(y)^{3}=(2x+y)\{(2x)^{2}-2\cdot x\cdot y+(y)^{2}\}}[/tex]

[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{(2x)^{3}+(y)^{3}=(2x+y)(4x^{2}-2xy+y^{2})}}}[/tex]

Hence , The product (2x+y) (4x²-2xy+y²) would result in the sum of cubes of 2x & y :D

Answer: See below

Step-by-step explanation:

ΔPQR ≈ ΔABC because PR  & AC are same line

So PQ ║ AB   &  QR ║ BC

In equation form: PQ / AB  = QR / BC

8/AB  = 2/BC

AB = 4BC

Perimeter of ABCD rectangle = 2(AB + BC)

= 2(4BC + BC)

= 10BC

Perimeter of the rectangle = 60 cm

In equation form: 10BC = 60

BC = 6  cm

AB = 4BC = 24 cm

Length of AB = 24 cm & length of BC = 6 cm

perimeter=2l+2b

perimeter=80=2l(10mm)

perimeter=80=2l+20

perimeter 22

The factors of a polynomial function are the zeros of the function

It is true that x - 3 is a factor of m(x) = x^3 - x^2 - 5x - 3

The function is given as:

m(x) = x^3 - x^2 - 5x - 3

The factor is given as:

x - 3

Set the factor to 0

x - 3 = 0

Solve for x

x = 3

Substitute 3 for x in the function

m(3) = 3^3 - 3^2 - 5(3) - 3

Evaluate

m(3) =0

Since the value of m(3) is 0, then x - 3 is a factor of m(x) = x^3 - x^2 - 5x - 3

Answer:

5x-7 has to equal to something smaller than 13

5x-7=5

Answer: x < 4

Step-by-step explanation:

Disregarding the lesser than sign, we can treat this equation as 5x-7=13. This doesn't work all the time as there are rules, but those rules don't apply to a simple inequality such as this.

5x-7<13

5x<20

x<4

And so, our answer is x<4

Answer:

60km

Step-by-step explanation:

There are two ways to look at this

1. Finding the unit rate

We can find how many km he travels in 1 hour by diving both the hours and km by 2. 1 hour = 10km so 6 hours is 60km since we multiply by 6.

2. Multiply by 3

We can multiply both the km and hours by 3, since 2x3=6 hours

20km * 3 hours = 60km

Answer:

R 694.4

Explanation:

simple interest = [tex]\sf{\dfrac{PRT}{100}[/tex] → [tex]\sf \dfrac{560*8*3}{100}[/tex] → R 134.4

where p refers to principal, r refers to rate, t refers to time.

total money:

invested money + simple interest

R 134.4 + R 560 → R 694.4

Answer:

R 694.40

Step-by-step explanation:

Simple interest formula:

A = P(1 + rt)

where A is the final amount, P is the initial principal balance, r is the annual interest rate (in decimal format), and t is time (in years)

Given:

⇒ A = 560(1 + 0.08 · 3)

⇒ A = 560(1.24)

⇒ A = 694.40

Answer:

1: B

2: H

3. C or D (it's hard to tell, especially without an equation)

4. J

5. A

6. G

7. B

Step-by-step explanation:

1:

f(x) - g(x)

(x^2 + 8x) - (3x - 5)    Distribute the negative

x^2 + 8x - 3x + 5       Combine like terms

x^2 + 5x + 5

2:

f(g(x))

Plug g(x) into f(x)

(2x - 1)^2 - 3

Immediately we can see that there will be a 4x^2 (because 2x times 2x = 4x^2) so we know the answer will be H because that's the only option with 4x^2

3:

The line starts at -4 on the x axis and goes infinitely to the right so everything greater than (and maybe equal to) -4.

On the y axis, the line starts at 0 and goes infinitely up so everything greater than (and maybe equal to) 0.

4:

To find the inverse of a function:

f(x) -> y

Switch x and y

Solve for y again

x = 3 +5y

x-3 = 5y

(x-3)/5 = y

5:

If option A were inverse functions, h(x) would be

x = 2y + 9

x - 9 = 2y

(x-9)/2 = y

Which could also be written as (1/2)x - 9/2 or (1/2)x - 4.5 but not (1/2)x - 9

6:

As y approaches -1, x approaches 1. Going the other direction,

As y approaches positive infinity, x approaches positive infinity.

7:

The number inside directly affecting the x moves the function left and right (left is positive, right is negative). The number outside moves the function up and down. So (x + 4) moves it left 4 and the +1 moves it up 1.
