35-{15-(19+5)3 Simplify
Answer 2

Answer:

38

Step-by-step explanation:

We know that:

Rule: Always simplify the innermost bracket first.Given expression: 35 - {15 - (19 + 5)} ÷ 3

Solution:

35 - {15 - (19 + 5)} ÷ 3=> 35 - {15 - (24)} ÷ 3=> 35 - {15 - 24} ÷ 3=> 35 - {-9} ÷ 3=> 35 + 9 ÷ 3=> 35 + 3=> 38

Hence, the simplified answer is 38.

Step-by-step explanation:

The front face can be considered as a 5×10 rectangle with a 3×6 rectangle cut from it. Then its area is ...

  A = (5×10) -(3×6) = 32 . . . square feet

The volume of a prism of uniform cross section is ...

  V = Bh . . . . . where B is the area of the base, and h is the height

How to do the inverse of a 3x3 matrix gaussian elimination.

Answers

As an example, let's invert the matrix

[tex]\begin{bmatrix}-3&2&1\\2&1&1\\1&1&1\end{bmatrix}[/tex]

We construct the augmented matrix,

[tex]\left[ \begin{array}{ccc|ccc} -3 & 2 & 1 & 1 & 0 & 0 \\ 2 & 1 & 1 & 0 & 1 & 0 \\ 1 & 1 & 1 & 0 & 0 & 1 \end{array} \right][/tex]

On this augmented matrix, we perform row operations in such a way as to transform the matrix on the left side into the identity matrix, and the matrix on the right will be the inverse that we want to find.

Now we can carry out Gaussian elimination.

• Eliminate the column 1 entry in row 2.

Combine 2 times row 1 with 3 times row 2 :

2 (-3, 2, 1, 1, 0, 0) + 3 (2, 1, 1, 0, 1, 0)

= (-6, 4, 2, 2, 0, 0) + (6, 3, 3, 0, 3, 0)

= (0, 7, 5, 2, 3, 0)

which changes the augmented matrix to

[tex]\left[ \begin{array}{ccc|ccc} -3 & 2 & 1 & 1 & 0 & 0 \\ 0 & 7 & 5 & 2 & 3 & 0 \\ 1 & 1 & 1 & 0 & 0 & 1 \end{array} \right][/tex]

• Eliminate the column 1 entry in row 3.

Using the new aug. matrix, combine row 1 and 3 times row 3 :

(-3, 2, 1, 1, 0, 0) + 3 (1, 1, 1, 0, 0, 1)

= (-3, 2, 1, 1, 0, 0) + (3, 3, 3, 0, 0, 3)

= (0, 5, 4, 1, 0, 3)

[tex]\left[ \begin{array}{ccc|ccc} -3 & 2 & 1 & 1 & 0 & 0 \\ 0 & 7 & 5 & 2 & 3 & 0 \\ 0 & 5 & 4 & 1 & 0 & 3 \end{array} \right][/tex]

• Eliminate the column 2 entry in row 3.

Combine -5 times row 2 and 7 times row 3 :

-5 (0, 7, 5, 2, 3, 0) + 7 (0, 5, 4, 1, 0, 3)

= (0, -35, -25, -10, -15, 0) + (0, 35, 28, 7, 0, 21)

= (0, 0, 3, -3, -15, 21)

[tex]\left[ \begin{array}{ccc|ccc} -3 & 2 & 1 & 1 & 0 & 0 \\ 0 & 7 & 5 & 2 & 3 & 0 \\ 0 & 0 & 3 & -3 & -15 & 21 \end{array} \right][/tex]

• Multiply row 3 by 1/3 :

[tex]\left[ \begin{array}{ccc|ccc} -3 & 2 & 1 & 1 & 0 & 0 \\ 0 & 7 & 5 & 2 & 3 & 0 \\ 0 & 0 & 1 & -1 & -5 & 7 \end{array} \right][/tex]

• Eliminate the column 3 entry in row 2.

Combine row 2 and -5 times row 3 :

(0, 7, 5, 2, 3, 0) - 5 (0, 0, 1, -1, -5, 7)

= (0, 7, 5, 2, 3, 0) + (0, 0, -5, 5, 25, -35)

= (0, 7, 0, 7, 28, -35)

[tex]\left[ \begin{array}{ccc|ccc} -3 & 2 & 1 & 1 & 0 & 0 \\ 0 & 7 & 0 & 7 & 28 & -35 \\ 0 & 0 & 1 & -1 & -5 & 7 \end{array} \right][/tex]

• Multiply row 2 by 1/7 :

[tex]\left[ \begin{array}{ccc|ccc} -3 & 2 & 1 & 1 & 0 & 0 \\ 0 & 1 & 0 & 1 & 4 & -5 \\ 0 & 0 & 1 & -1 & -5 & 7 \end{array} \right][/tex]

• Eliminate the column 2 and 3 entries in row 1.

Combine row 1, -2 times row 2, and -1 times row 3 :

(-3, 2, 1, 1, 0, 0) - 2 (0, 1, 0, 1, 4, -5) - (0, 0, 1, -1, -5, 7)

= (-3, 2, 1, 1, 0, 0) + (0, -2, 0, -2, -8, 10) + (0, 0, -1, 1, 5, -7)

= (-3, 0, 0, 0, -3, 3)

[tex]\left[ \begin{array}{ccc|ccc} -3 & 0 & 0 & 0 & -3 & 3 \\ 0 & 1 & 0 & 1 & 4 & -5 \\ 0 & 0 & 1 & -1 & -5 & 7 \end{array} \right][/tex]

• Multiply row 1 by -1/3 :

[tex]\left[ \begin{array}{ccc|ccc} 1 & 0 & 0 & 0 & 1 & -1 \\ 0 & 1 & 0 & 1 & 4 & -5 \\ 0 & 0 & 1 & -1 & -5 & 7 \end{array} \right][/tex]

So, the inverse of our matrix is

[tex]\begin{bmatrix}-3&2&1\\2&1&1\\1&1&1\end{bmatrix}^{-1} = \begin{bmatrix}0&1&-1\\1&4&-5\\-1&-5&7\end{bmatrix}[/tex]

Malik used these steps to solve the system of equations. 2 x 4 y = 20. 5 x minus 3 y = 11. Step 1 6 x 12 y = 60. 20 x minus 12 y = 44. Step 2 Step 3 x = 4 Step 4 2 (4) 4 y = 20. 8 4 y = 20. 4 y = 12. Y = 3. Step 5 The solution is (4, 3). What needs to be done in step 2? Divide both sides of the equations in step 1 by the same number to eliminate one variable. Multiply both sides of the equations in step 1 by the same number to eliminate one variable. Add the equations in step 1 to eliminate one variable. Subtract the equations in step 1 to eliminate one variable.

Answers

The "step 2" that Malik should take in order to solve the given system of equations is to add both equations.

Given to us

2x + 4y = 205x - 3y = 11

Step 1: Multiply the first equation with 3, while the second equation with 4,

6x + 12 y = 60

20x - 12 y = 44

Step 2: Add both the equations,

(6x + 12y) + (20x - 12y) = 60+44

Step 3: caluculate the value of x,

x = 4

Step 4: Substitute the value of x in equation 1,

2(4) + 4y = 20

8 + 4y = 20.

4y = 12

Y = 3

Step 5: The solution is (4, 3).

Hence, the "step 2" that Malik should take in order to solve the given system of equations is to add both equations.

Jerome's average balance checking account pays simple interest of 7. 2% annually, and he made $5. 28 in interest last month. What was Jerome's average balance last month?.

Answers

Simple interest is the amount charged on the principal amount with a fixed rate of interest for a time period.

The balance of the last month of Jerome's account is $880

What is simple interest?

Simple interest is the amount charged on the principal amount with a fixed rate of interest for a time period. Simple interest calculated only on the principal amount.

The formula for the simple interest can be given as,

[tex]I=\dfrac{P\times r\times t}{100}[/tex]

Here, [tex]I[/tex] is the interest rate on the principal amount of [tex]P[/tex] with the rate of [tex]r[/tex] in the time period of [tex]t[/tex].

Given information-

Jerome's average balance checking account pays simple interest of 7.2% annually.

Jerome made $5.28 in interest last month.

Convert the interest rate monthly as,

[tex]r=\dfrac{7.2}{12} \\r=0.6[/tex]

Thus the monthly interest rate is 0.6 percent.

Suppose the balance of the last month is [tex]P[/tex]. Use the above formula to find the principal amount,

[tex]I=\dfrac{P\times r\times t}{100}\\5.28=\dfrac{P\times 0.6\times 1}{100}[/tex]

Solve it for [tex]P[/tex],

[tex]P=\dfrac{5.28\times100}{0.6\times1} \\P=\dfrac{528}{0.6} \\P=880[/tex]

Hence, The balance of the last month of Jerome's account is $880.

Answers

After the store gives 20% off sale, the expression of the item at price p can be written as, p-0.2=0.8p.

Given to us

A store is having a 20% off sale.

The sale price of an item with price p is p – 0. 2p.

What is the total price of the item?

We know that for any item the price can be 100%(1.00) of itself, therefore, the price of the item will be p.

What is the expression is equivalent to?

We know that for any item the price can be 100%(1), therefore, after giving 20%(0.2) off sale, the price will be 80%(1-0.2 = 0.8) of the original.

Thus, the expression is equivalent to

[tex](100\%)p-(20\%)p = 80\%p\\\\1p-0.2p = 0.8p\\\\p-0.2p=0.8p[/tex]
