Indeed, so they have.

You would need approximately 225 mL of the 70% alcohol mixture to obtain the desired 55% solution.

To find out how much of the 70% alcohol mixture you need to obtain a 55% solution, we can set up an equation based on the principle of mixing concentrations.

Let's assume you need "x" mL of the 70% alcohol mixture.

First, we'll determine the amount of alcohol in the 10% alcohol mixture:

Alcohol in 10% mixture = 10% of 75 mL

= (10/100) × 75 mL

= 7.5 mL

Next, we'll determine the total amount of alcohol in the desired 55% solution:

Alcohol in 55% solution = 55% of (75 mL + x mL)

We want the amount of alcohol in the 55% solution to be equal to the sum of the alcohol in the 10% mixture and the alcohol in the x mL of the 70% mixture.

Therefore, we can set up the equation:

Alcohol in 55% solution = Alcohol in 10% mixture + Alcohol in 70% mixture

55% of (75 mL + x mL) = 7.5 mL + 0.7x mL

Now, let's solve for "x" to find the amount of the 70% alcohol mixture needed:

0.55 × (75 mL + x mL) = 7.5 mL + 0.7x mL

41.25 mL + 0.55x mL = 7.5 mL + 0.7x mL

0.55x mL - 0.7x mL = 7.5 mL - 41.25 mL

-0.15x mL = -33.75 mL

x mL = (-33.75 mL) / (-0.15)

x mL ≈ 225 mL

Therefore, you would need approximately 225 mL of the 70% alcohol mixture to obtain the desired 55% solution.

Answer:

The cappuccinos cost $3.59 each and the caffe lattes cost $4.19 each

Step-by-step explanation:

Let's call:

x= price of each cappuccino

y= price of each caffe latte

According to the statement, two cappuccinos and three caffe lattes cost $19.75, thus:

\(2x+3y=19.75\qquad\qquad [1]\)

Also, one cappuccino and two caffe lattes cost $11.97, thus:

\(x+2y=11.97\qquad\qquad [2]\)

The equations [1] and [2] form a system of equations. We'll solve it by elimination.

Multiply [2] by -2:

\(-2x-4y=-23.94\qquad\qquad [3]\)

Add [1] and [3]:

\(3y-4y=-4.19\)

Simplifying:

\(-y=-4.19\)

Solving:

\(y=4.19\)

From [2] we have:

\(x=11.97-2y\)

\(x=11.97-2*4.19=3.59\)

x=3.59

The cappuccinos cost $3.59 each and the caffe lattes cost $4.19 each

Answer:

No, the zeros of the function are at x = 3/4 and x = –2

Step-by-step explanation:

the equation

4x² + 5x – 6 = 0

(note: since there is a coefficient of x² we need to multiply it to the last term(6))

4x² + 5x – 24 = 0

the factors are :- 8x and – 3x

4x² + 8x – 3x – 6 = 0

4x( x + 2) –3( x + 2) = 0

( 4x – 3)( x + 2) = 0

the zeros will be

4x – 3 = 0

4x = 3

\(x = \frac{3}{4} \)

x + 2 = 0

x = – 2

the zeros are x= 3/4 or –2

The slope intercept form of the given equation is,

y = 5x - 1/4

Given an equation of a line as,

5x - y = 1/4

We have to write the equation of the line in slope intercept form.

Equation of the line in slope intercept form is,

y = mx + c

Here m is the slope and c is the y intercept.

Rearranging the given equation,

5x = y + 1/4

5x - 1/4 = y

or,

y = 5x - 1/4

Hence the slope intercept form is y = 5x - 1/4.

Step-by-step explanation:

Given:

height (h) = 10 in.

Base area (B) = 9 in.²

Required:

Volume of the pyramid

Solution:

Formula for finding volume of triangular pyramid = ⅓(B)(h)

Plug in the values

V = (3)(10)

V = 30 cubic inches

The slope of a ramp with a height-to-distance ratio of 1 to 12 feet is 4.76 degrees.

The slope or gradient of a line in mathematics is a number that describes both the direction and the steepness of the line. The tangent relation or the height-to-distance ratio helps to determine the slope of the line.

It is given that the height-to-distance ratio of a slope is given as 1 to 12 feet.

So,

\(\tan \alpha = 1/12\\\alpha= \tan^{-1}1/12\\\alpha= 4.76^\circ\)

So, the slope of the ramp is about 4.76 degrees.

Answer:

Third choice on the screenshot:
Yes, because the determinant of the coefficient matrix is 8

Step-by-step explanation:

If the determinant of a coefficient matrix is zero, then the linear system of equations it represents has no solution.

Here the coefficient matrix is

\(\begin{pmatrix}2&4\\ \:-1&2\end{pmatrix}\)

The determinant of a matrix
\(\begin{pmatrix}a\:&\:b\:\\ c\:&\:d\:\end{pmatrix}\)

The total amount paid by the customer will be $32,262.5 and the amount of the interest will be $ 2,262.5.

APR on a credit card is the way of saying that the interest you are charged over a year is equal to roughly of your balance.

Suppose you walk in to buy a $30,000 car, and you are able to put $3,000 down.

Your dealer initially offers $3,000 for your trade.

You couldn't get to your bank in time, so you finance through the dealer.

They are currently able to offer you a 4% interest rate for 48 months.

After the down payment, the amount will be

P = $ 27,000

r = 4% = 0.00333

n = 48 months

Then the cost of the monthly payment will be

\(\rm MP = P r \times \dfrac{(1+r)^n}{(1+r)^n - 1}\\\\MP = 27000 \times 0.0033 \times \dfrac{(1 + 0.0033)^{48}}{(1+0.0033)^{48} - 1}\\\\MP = 609.63\)

Then the total amount paid by the customer will be

Total amount = 3000 + 609.63 × 48

Total amount = $ 32,262.5

Then the amount of the interest will be given as

Interest amount = $32,262.5 - $30,000

Interest amount = $ 2,262.5

Answer:

\(P(x)=x^3+12x^2+45x+50\)

Step-by-step explanation:

Roots of a polynomial

If we know the roots of a polynomial, say x1,x2,x3,...,xn, we can construct the polynomial using the formula

\(P(x)=a(x-x_1)(x-x_2)(x-x_3)...(x-x_n)\)

Where a is an arbitrary constant.

We are given the following roots:

-5 multiplicity 2 (-5 twice)

-2 multiplicity 1

Thus, the polynomial is:

\(P(x)=a(x-(-5))(x-(-5))(x-(-2))\)

\(P(x)=a(x+5)(x+5)(x+2)\)

We are not given any clue about the value of a, so we choose a=1. Multiplying:

\(P(x)=(x^2+5x+5x+25)(x+2)=(x^2+10x+25)(x+2)\)

\(P(x)=x^3+2x^2+10x^2+20x+25x+50\)

Simplifying:

\(\mathbf{P(x)=x^3+12x^2+45x+50}\)
