Diane's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Diane $4.05 per pound, and type B coffee costs $5.55 per pound. This month's blend used four times as many pounds of type B coffee as type A, for a total cost of $735.00. How many pounds of type A coffee were used

Answers

Step-by-step explanation:

Type A cost 4.05 dollars per pound

Type B cost 5.55 dollars per pound

now...since type A is four times larger than Type B for that month,.the ratio will be 4:1 respectively

total cost was 735 dollars out of which Type A has

4/5 × 735 = 588 dollars while Type B has 1/5 × 735 = 147 dollars

so therefore ....number of pounds of A = 588/4.05=145.18pounds

and number of Pounds of B = 147/5.55= 26.48pounds

Factorise x^2 + 10x + 16

Answers

Answer: (x+8)(x+2) = x^2 + 10x + 16

Answer: [tex](x+2)(x+8)[/tex]

Step-by-step explanation:

1) First, we need to see which number multiplies to 16 and adds up to 10.

By looking at the factors of 16, we can see that only 2 and 8 will work.

2) Now, we need to arrange them in the factorized equation, which is always

(x+r)(x+q).

3) This will give us our final equation:

[tex](x+2)(x+8)[/tex]

If you want the roots, just do the negation of r and q and you will get it!

which of the following fractions is closest to 5/8. 2/3, 13/20 or 11/16​

Answers

The closest to 5/8 is 13/20. Convert the fractions to decimals and then compare.

A fraction is a way to describe a part of a whole. The fraction that is closest to 5/8 is 13/20.

What is a Fraction?

A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.

Know the fraction that will be close to 5/8 can be found by taking the LCM of denominators. Therefore, the LCM of 8, 3, 20, and 16 is 240.

Thus, the fractions can be rewritten as,

5/8 = (5/8) × (30/30) = 150/240

2/3 = (2/3) × (80/80) = 160/240

13/20 = (13/20) × (12/12) = 156/240

11/16​ = (11/16) × (15/15) = 165/240

Now as it can be seen that 156/240 is closest to 150/240, therefore, the fraction that is closest to 5/8 is 13/20.

6. Find the total bill:
5 golf clubs at $18.65 each
60 golf balls at $16.50 per dozen
I pair of golf shoes at $75.80
Sales tax at 15% is added to the total cost.
hers who cach pay $​

Answers

First multiply all the items up with their correct prices.

5 Golf Clubs = 18.65 each

5 x 18.65 = 93.25

60 Golf Balls = 16.50 per dozen

60 = 5 dozen

5 x 16.50 = 82.5

1 pair of golf shoes = 75.80

1 x 75.80 = 75.80

Now, add them all up.

93.25 + 82.5 + 75.80 = 251.55

Lastly, multiply by 1.15 to add the 15% sales tax.

251.55 x 1.15 = 289.28

Thus, the total cost of all the equipment with tax is $289.28

I WILL CHOOSE BRAINIEST AND 5 STARS AND A THANKS... A "necklace" is a circular string with several beads on it. It is allowed to rotate a necklace but not to turn it over. How many different necklaces can be made using 13 different beads?

Answers

Answer:

479,001,600 ways

Step-by-step explanation:

When looking at this problem, there are 13 beads that can be put on first, 12 that can be put on second as the first one was already used, 11 put on third, and so on. This means the amount of necklaces you can make are 13*12*11...*2*1, or 13 factorial (13!). But since you can rotate the necklace this means that there are each combination has 12 others just like it, just rotated(13 in total). This means we must divide 13! by 13, which makes it 12!. 12! is equal to 479,001,600, which is the answer.

Answer:

6,227,020,800 different necklaces.

Step-by-step explanation:

To start making the necklace, you will have to choose one of the 13 beads. For the next bead, you will have 13 - 1 = 12 beads to choose from. For the next bead, you will have 12 - 1 = 11 beads to choose from, and so on and so forth, until all 13 beads are used.

So, you will have 13! different necklaces, since you would have 13 * 12 * 11 * 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 = 156 * 110 * 72 * 42 * 120 = 17160 * 362880 = 6227020800.

So, you will have 6,227,020,800 different necklaces.

Drag each factor to the correct location on the image. If p(1) = 3, p(-4) = 8, p(5) = 0, p(7) = 9, p(-10) = 1, and p(-12) = 0, determine which expressions are factors of the polynomial p(x).

Answers

Answer:

Step-by-step explanation:

Recall that when we are factoring a polynomial, we are implicitly finding its roots. By finding a root, we are looking for a value of x (say c) such that p(c) =0. When this happens, our polynomial has the the polynomial (x-c) as a factor.

We are given the values of p at some values of x. We notice that p(5) = 0 and p(-12) =0. So, this means that our polynomial has as a factor the polynomials (x-5) and (x+12).

Answer:

Factor: x-5 & x+12

Not a Factor: x-1, x+4, x-7, x+10

Step-by-step explanation:

The remainder theorem states that for a polynomial p(x) and a number a, the remainder on division of p(x) by x − a is p(a). So, p(a) = 0 if and only if x − a is a factor of p(x).

Since, p(5) = 0 and p(-12) = 0, the expressions (x − 5) and (x + 12) are factors of the polynomial p(x).

If 19300 dollars is invested at an interest rate of 9 percent per year, find the value of the investment
at the end of 5 years for the following compounding methods, to the nearest cent.

Answers

Answer:

$296,954.42

Step-by-step explanation:

If any amount P is invested at rate of r% per year for n years then value of money p after n years is given by

FV = p(1 + r/100)^n

where FV is the future value of money after n years.

given

p= $19300

r = 9%

n = 5 years

Thus, FV = 193000(1 + 9/100)^5

FV =  193000((100 + 9)/100)^5

FV =  193000(109/100)^5

FV =  $296,954.42

Thus, value after 5 years for the investment is $296,954.42 to the nearest cent

What is the solution to this system of linear equations? 2x + y = 1 and 3x - y = -6

Answers

Answer:

(- 1, 3 )

Step-by-step explanation:

Given the 2 equations

2x + y = 1 → (1)

3x - y = - 6 → (2)

Adding the 2 equations term by term eliminates the y- term, that is

5x = - 5 ( divide both sides by 5 )

x = - 1

Substitute x = - 1 into either of the 2 equations and evaluate for y

Substituting into (1)

2(- 1) + y = 1

- 2 + y = 1 ( add 2 to both sides )

y = 3

Solution is (- 1, 3 )

Urn A contains seven white balls and five black balls. Urn B contains four white balls and six black balls. A ball is drawn from Urn A and then transferred to Urn B. A ball is then drawn from Urn B. What is the probability that the transferred ball was black given that the second ball drawn was black

Answers

Answer:

P(X/Y) = 0.4545

Step-by-step explanation:

Let's call X that the transferred ball is black, X' that the transferend ball is white and Y the event that the second ball drawn is black.

The probability that the transferred ball was black given that the second ball drawn was black is equal to:

P(X/Y) = P(X∩Y)/P(Y)

Where P(Y) = P(X∩Y) + P(X'∩Y)

Then, the probability P(X∩Y) that the transferred ball is black and the second ball drawn is black is equal to:

P(X∩Y) = (5/12)*(7/11) = 0.2651

Because the urn A has 12 balls and 5 of them are black, then if the transferred ball is black, the urn B will contain 11 balls and 7 of them will be black balls.

At the same way, the probability P(X'∩Y) that the transferred ball is white and the second ball drawn is black is equal to:

P(X'∩Y) = (7/12)*(6/11) = 0.3181

Because the urn A has 12 balls and 7 of them are white, then if the transferred ball is white, the urn B will contain 11 balls and 6 of them will be black balls.

So, P(Y)  and P(X/Y) are equal to:

P(Y) = 0.2651 + 0.3181

P(Y) = 0.5832

P(X/Y) = 0.2651/0.5832

P(X/Y) = 0.4545

Answers

Answer: £ 8

Step-by-step explanation:

Total hours Lena works from Monday to Friday = 34 hours

Hours she works on Saturdays = 4

Overtime rate of Saturday = 1.5 times her normal rate

Let x be the normal rate.

Then , Her total earning = [tex]34 x + 4 \times(1.5x) =34x+6x=40x[/tex]

Since her total earnings for week = £ 320

So,

[tex]320=40x\\\\\Rightarrow\ x=\dfrac{320}{40}\\\\\Rightarrow\ x=8[/tex]

Thus, her normal rate of pay per hour = £ 8

In each pound there are 16 ounces. We can divide $9.60 by 5 to get the cost of one pound of flour, and then divide the result of that by 16 to get the price of flour by the ounce.

$9.60 can be converted to 960 cents to make it easier to divide.
