Answer:

Stephanie requires 835.75 square feet more amount of soil to cover her yard.

Step-by-step explanation:

Given:

Total square feet of yard she need to cover with soil = \frac{4103}{4}\ ft^2

\frac{4103}{4}\ ft^2 can be rewritten as 1025.75 square feet.

Total square feet of yard she need to cover with soil = 1025.75\ ft^2

Amount of soil in one bag = 125\ ft^2

Amount of soil in other bag = 65\ ft^2

Total Amount of soil she has is equal to sum of Amount of soil in one bag and Amount of soil in other bag.

Framing the equation we get;

Total Amount of soil she has= 125+65 = 190\ ft^2

Now We need to find the Amount of soil she required more to cover the yard.

Amount of soil she required more is equal to difference of Total Amount of soil she has and Total square feet of yard she need to cover with soil.

Framing the equation we get;

Amount of soil she required more = 1025.75-190= 835.75\ ft^2

Hence Stephanie requires 835.75 square feet more amount of soil to cover her yard.

Solve the system of equations. y = x − 5 and y = x2 − 5x + 3 A. (-4,-9) and (-2,-7) B. (4,-9) and (2,-7) C. (4,-3) and (2,-1) D.
larisa [96]

Answer:

D

Step-by-step explanation:

Given the 2 equations

y = x - 5 → (1)

y = x² - 5x + 3 → (2)

Substitute y = x² - 5x + 3 into (1)

x² - 5x + 3 = x - 5 ← subtract x - 5 from both sides

x² - 6x + 8 = 0 ← in standard form

(x - 2)(x - 4) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 2 = 0 ⇒ x = 2

x - 4 = 0 ⇒ x = 4

Substitute each of these values into (1) for corresponding values of y

x = 2 → y = 2 - 5 = - 3 ⇒ (2, - 3 )

x = 4 → y = 4 - 5 = - 1 ⇒ (4, - 1 )

Calculate 3n-1 for n equals 2 to 10 explain how you know that the numbers are composite
Troyanec [42]

composite number means a number that can be formed by multiplying two smaller numbers

3n-1 for n=2, 3n-1=3*2-1=6-1=5

3n-1 for n=10, 3n-1=3*10-1=30-1=29

5 is composite because 2*2.5=5

29 is composite because 5*5.8=29

My name is Ann [436]

Answer: Hello there!!! the answer is - 91


Step-by-step explanation:

Step 1: convert all of the variables in the equation into numbers.

The equation will look like this - 8^2 + 3^3

Step 2: solve 8^2 and 3^3

8^2 = 64 and 3^3 = 27

Step 3: solve the equation sooooo the equation will now look like this

64 + 27 which is 91
