Answer:

250 of 65% acid

100 gallons of 30% acid

Really sorry if this is incorrect, I had this question on my Lesson 16 test, and I don't know if it's correct or not...

Following are the calculation to the given question:

Assuming

x=The number of gallons of pure acid [tex](50\%)[/tex]

y = The number of liters of pure acid at [tex](80\%)[/tex] a concentration

[tex]\to x+y = 350[/tex]

The total quantity of gallons of each of the two types of pure acids............(1)

[tex]\to 0.65x+0.30y = 0.55(x+y)[/tex]

the mixture's acidity

[tex]\to 0.65x+0.30y = 0.55(350)\\\\\to 0.65x+0.30y = 192.5 ..........(2)[/tex]

So we have two equations and two variables to work with.

[tex]\to x+y = 350\\\\\to 0.65x+0.30y = 192[/tex]

multiply the first equation by [tex]0.30[/tex]

[tex]\to 0.30x+0.30y = 105\\\\\to 0.65x+0.30y = 192[/tex]

Subtract the second equation from the first

[tex]\to 0.35x = 87\\\\\to x = 248. 57 \approx 248 \ gallons\\\\ \to y = 350-248 = 102\ gallons\\\\[/tex]

As a result, we'll need 248 gallons of 65% pure acid and 102 gallons of 30% pure acid.

Answer:

[tex]y = -2[/tex]

Step-by-step explanation:

Given

Horizontal Line

[tex](x_1,y_1) = (4,-2)[/tex]

Required

Determine the equation

The equation is calculated using:

[tex]y - y_1 =m(x-x_1)[/tex]

Where

[tex]m = slope[/tex]

Because the line is a horizontal line, then:

[tex]m = 0[/tex]

Substitute 0 for m and values for x1 and y1 in [tex]y - y_1 =m(x-x_1)[/tex]

[tex]y - (-2) = 0(x -4)[/tex]

[tex]y +2 = 0(x -4)[/tex]

[tex]y +2 = 0[/tex]

Subtract 2 from both sides

[tex]y +2-2 = 0-2[/tex]

[tex]y = -2[/tex]

Hence, the equation is: [tex]y = -2[/tex]

Answer:

11(4-1)

Step-by-step explanation:

11 is the greatist common factor of 44 and 11 so you factor an 11 out of both terms

44/11=4

11/11=4

Therefore the answer is 11(4-1)

Step-by-step explanation:

Answer:

360

Step-by-step explanation:

We need to find the LCM of 18,90 and 24.

The prime factorization of 18 = 2 × 3 × 3

The prime factorization of 90 = 2 × 5×3×3

The prime factorization of 24 = 2 × 3×2×2

LCM is least common multiple.

LCM = 2 x 2 x 2 x 3 x 3 x 5

= 360

Hence, the LCM of 18,90 and 24 is 360.

Answer:

The total cost = $90

Step-by-step explanation:

As, $75 is the cost of the meal

And tip is 20%

So 20% of $75 = 15

So, the tip = $15

So, total = Cost of meal + tip

= $75 + $15 = $90

Answer:

[tex]\huge\boxed{\text{E. } \frac{1}{2} }[/tex]

Step-by-step explanation:

When finding the cosine of an angle, we need to note what each terms mean.

Using the acronym SOH CAH TOA, we know that the

Cosine of an angle will be it's

Adjacent side divided by the

Hypotenuse.

The side adjacent to the 60° angle is 1, and the hypotenuse of the triangle is 2. Therefore, the adjacent over the hypotenuse is [tex]\frac{1}{2}[/tex], making the cos of 60°

[tex]\frac{1}{2}[/tex].

Hope this helped!
