In total Julian buys about 11.4 pounds of potatoes by spending $5.58 on red potatoes and $4.68 on yellow potatoes.

To find the total amount of potatoes that Julian buys,  divide the total cost of each type of potato by the cost per pound.

Red potatoes cost $5.58 and cost $0.90 per pound, so in total Julien buys the next few pounds of red potatoes.

5.58 ÷ 0.90 ≈ 6.2 pounds (rounded to one decimal place)

Similarly, yellow potatoes cost him $4.68 and cost $0.90 per pound, so the total pounds of yellow potatoes that Julian buys would be:

4.68 ÷ 0.90 ≈ 5.2 pounds (rounded to one decimal place)

To find the total amount of potatoes that Julian bought, add the pounds of red potatoes and the pounds of yellow potatoes.

6.2 + 5.2 ≈ 11.4 pounds (rounded to one decimal place)

So in total Julian buys about 11.4 pounds of potatoes.

Step-by-step explanation:

if you distribute and simplify:

4x-12 = 12+4x-8

4x-12 = 4x+4

-12 ≠ 4

Answer:

\(x = - \frac{1}{3} \)

Step-by-step explanation:

1) Simplify 2 - 6 to -4.

\(2x \times - 4 = 4(3 + 1 \times x - 2)\)

2) Simplify 1 × x to x.

\(2x \times - 4 = 4(3 + x - 2)\)

3) Simplify 3 + x - 2 to x + 1.

\(2x \times - 4 = 4(x + 1)\)

4) Simplify 2x × -4 to -8x.

\( - 8x = 4(x + 1)\)

5) Divide both sides by 4.

\( - 2x = x + 1\)

6) Subtract x from both sides.

\( - 2x - x = 1\)

7) Simplify -2x - x to -3x.

\( - 3x = 1\)

8) Divide both sides by -3.

\(x = - \frac{1}{3} \)

The work required to pump the oil over the top of the tank is 1.5080 × 10⁶

Given:

We start as we often do: we partition an interval into sub intervals. We orient our tank vertically since this makes intuitive sense with the base of the tank at  y=0 . Hence the top of the oil is at  y=10 , meaning we are interested in subdividing the  y -interval  [0,10]  into  n  sub intervals as

0 = y₁ < y₂ < ..... <yₙ₊₁ = 15

Consider the work  Wi  of pumping only the oil residing in the  ith  sub interval. The force required to move this oil is equal to its weight which we calculate as volume  ×  density. The volume of oil in this sub interval is  Vi=5²πΔyi ; its density is  48  lb/ft ₃ . Thus the required force is  4800πΔyi  lb.

We approximate the distance the force is applied by using any  y -value contained in the  ith  sub interval; for simplicity, we arbitrarily use  yi  for now (it will not matter later on). The oil will be pumped to a point 5 feet above the top of the tank, that is, to the height of  y=15  ft. Thus the distance the oil at height  yi  travels is  15−yi  ft.

In all, the approximate work  Wi  performed in moving the water in the  ith  sub interval to a point 5 feet above the tank is

Wi≈4800πΔyi(15−yi).

To approximate the total work performed in pumping out all the oil from the tank, we sum all the work  Wi  performed in pumping the oil from each of the  n  sub intervals of  [0,10] :

W≈∑i=1nWi=∑i=1n4800πΔyi(15−yi).

This is a Riemann sum. Taking the limit as the sub interval length goes to 0 gives

W=∫3006240π(35−y)dy

=6240π(35y−12y2)∣∣10 0

=  48000π ≈ 1.5080 × 10⁶

$3088.75

Step-by-step explanation:

4.25%= .0425
1750 x .0425 = 74.375

To find the fractional value of cos(B) in a right triangle with opposite side = 20, adjacent side = 34.66, and hypotenuse = 30, we can use the cosine function:

cos(B) = adjacent / hypotenuse

Plugging in the given values, we have:

cos(B) = 34.66 / 30

To simplify the fraction, we can divide both the numerator and denominator by their greatest common divisor (GCD). In this case, the GCD of 34.66 and 30 is 2.

Dividing 34.66 by 2 gives 17.33, and dividing 30 by 2 gives 15.

Therefore, the simplified fractional value of cos(B) is:

cos(B) = 17.33 / 15

Since the point B is between points A and C, the length BC is 22.25 units

From the question, we have the following parameters that can be used in our computation:

Length AB = 6x - 9

Length BC = 3x + 17

Length AC = 5x + 16

The above implies that the point B is between points A and C

So, we have the following equation

AC = AB + BC

Substitute the known values in the above equation

So, we have the following equation

5x + 16 = 6x - 9 + 3x + 17

Collect the like terms

So, we have the following equation

5x - 6x - 3x = -9 + 18 - 16

Evaluate the like terms

So, we have the following equation

-4x = -7

Divide by -4

x = 7/4

Substitute x = 7/4 in the equation BC = 3x + 17

So, we have the following equation

BC = 3 x 7/4 + 17

Evaluate

BC = 22.25

Hence, the numerical length of BC is 22.25 units

Answer:

2 = (2/3)*(6)+b

2 = 4+b

b= -2

so slope intercept form is y = (2/3)x -2

To find the point slope form, simply plug in m and the point given.

y-2 = (2/3)*(x-6)

Step-by-step explanation:

(a) (A, B) = 0, (b) ||A|| = √2, (c) ||B|| = √2, (d) d(A, B) = -1. These values are calculated using the given inner product formula and the matrices A and B.

Let's calculate the required values step by step

To find (A, B), we need to substitute the elements of matrices A and B into the given inner product formula:

(A, B) = 2(a₁₁)(b₁₁) + (a₁₂)(b₁₂) + (a₂₁)(b₂₁) + 2(a₂₂)(b₂₂)

Substituting the values from matrices A and B:

(A, B) = 2(1)(0) + (0)(1) + (0)(1) + 2(1)(0)

= 0 + 0 + 0 + 0

= 0

Therefore, (A, B) = 0.

To find ||A|| (norm of A), we need to calculate the square root of the sum of squares of the elements of A:

||A|| = √((a₁₁)² + (a₁₂)² + (a₂₁)² + (a₂₂)²)

Substituting the values from matrix A:

||A|| = √((1)² + (0)² + (0)² + (1)²)

= √(1 + 0 + 0 + 1)

= √2

Therefore, ||A|| = √2.

To find ||B|| (norm of B), we can follow the same steps as in part (b):

||B|| = √((b₁₁)² + (b₁₂)² + (b₂₁)² + (b₂₂)²)

Substituting the values from matrix B:

||B|| = √((0)² + (1)² + (1)² + (0)²)

= √(0 + 1 + 1 + 0)

= √2

Therefore, ||B|| = √2.

To find d(A, B), we need to calculate the determinant of the product of matrices A and B:

d(A, B) = |AB|

Multiplying matrices A and B:

AB = [10 + 01 11 + 00;

00 + 11 01 + 10]

= \(\left[\begin{array}{cc}0&1&\\1&0\\\end{array}\right]\)

Taking the determinant of AB:

|AB| = (0)(0) - (1)(1)

= -1

Therefore, d(A, B) = -1.

In the shape of a regular decagon,

Answer:

The two solutions of the equation is (0,-4)(6,0).

The nurse will add 40 mL of diluent to the vials, resulting in a dosage strength of 48 mg/mL. The nurse will administer 20 mL of reconstituted gemcitabine.

To calculate these values, we can use the information provided in the package insert. If each vial contains 200 mg of gemcitabine powder, then 5 vials would contain a total of 1000 mg. To prepare a dose of 960 mg, the nurse would need to use 4.8 mL of the reconstituted solution.

To determine the amount of diluent needed, we can use the formula:

Amount of Diluent = Total Volume - Amount of Powder

The total volume is the sum of the volumes of the powder and the diluent. If the package insert recommends a diluent volume of 40 mL per vial, then the total volume for 5 vials would be:

Total Volume = 5 x (4 mL + 40 mL) = 220 mL

So the amount of diluent needed is:

Amount of Diluent = 220 mL - 5 x 4 mL = 200 mL

Therefore, the nurse will add 40 mL of diluent to the vials.

The resulting dosage strength is:

Dosage Strength = Total Amount of Powder / Total Volume

Total Amount of Powder = 1000 mg

Total Volume = 200 mL

Dosage Strength = 1000 mg / 200 mL = 5 mg/mL

To administer a dose of 960 mg, the nurse would need to use:

Amount of Reconstituted Solution = Dose / Dosage Strength

Amount of Reconstituted Solution = 960 mg / 5 mg/mL = 192 mL

Rounding to the nearest tenth, the nurse will administer 20 mL of reconstituted gemcitabine.

The type of loan that Brady most likely getting  is option (a) conventional loan

Conventional loans are typically not guaranteed or insured by the government and often require a higher down payment compared to government-backed loans such as FHA or VA loans. The down payment requirement of $5,250, which is 3.5% of the purchase price, is lower than the typical down payment requirement for a conventional loan, which is usually around 5% to 20% of the purchase price.

ARM (Adjustable Rate Mortgage) loans have interest rates that can change over time, which can make them riskier for borrowers. FHA (Federal Housing Administration) loans are government-backed loans that typically require a lower down payment than conventional loans, but they also require mortgage insurance premiums.

VA (Veterans Affairs) loans are available only to veterans and offer favorable terms such as no down payment requirement, but not everyone is eligible for them. Fixed-rate loans have a fixed interest rate for the life of the loan, but the down payment amount does not indicate the loan type.
