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:

(x-3)² + (y+5)² = 16

Step-by-step explanation:

Radius will be half of diameter means that radius = r = 8/2 = 4.

With Center (h,k) the equation of circle is

(x-h)² + (y-k)² = r²

so by putting values answer will be

(x-3)² + (y+5)² = 4²

(x-3)² + (y+5)² = 16

2x-7 = 11

7 goes to the other side

2x=11+7

2x = 18

x=18/2

x=9

7x + 1 = 22

1 goes to the other side

7x=22 - 1

7x=21

x=3

3x - 8 = 22

8 goes to the other side

3x = 22+8

3x=30

x=10

8x+5 = 45

5 goes to the other side

8x=40

x=40/8

x=5

Given:

The graph of an exponential function.

To find:

The function in the form of [tex]f(x)=ab^x[/tex].

Solution:

The general form of an exponential function is

[tex]f(x)=ab^x[/tex]                ...(i)

From the given graph it is clear that the function passes through the points (0,4) and (1,7). It means these points will satisfy the function.

For x=0 and f(x)=4,

[tex]4=ab^0[/tex]

[tex]4=a(1)[/tex]

[tex]4=a[/tex]

For x=1 and f(x)=7,

[tex]7=ab^1[/tex]

Putting a=4, we get

[tex]7=4(b)[/tex]

[tex]\dfrac{7}{4}=b[/tex]

Substitute a=4 and [tex]b=\dfrac{7}{4}[/tex] in (i).

[tex]f(x)=4\left(\dfrac{7}{4}\right)^x[/tex]

Therefore, the required exponential function is [tex]f(x)=4\left(\dfrac{7}{4}\right)^x[/tex].

Step-by-step explanation: The bird decreases its heights by 12 feet which is what the question is asking.

Answer:

 y = 5x - 7

Step-by-step explanation:

(3 , 8) ; slope(m) = 5

Equation of the line: y - y₁ = m( x- x₁)

y - 8 = 5(x - 3)

y -8 = 5x - 5*3

y-8 = 5x - 15

   y = 5x - 15 +8

  y = 5x - 7

well that took alot of guesses...

Answer:

155

Step-by-step explanation:

( 25 x 4 ) + ( 3 x 15 ) + 10 = 155

Answer:

1/4

Step-by-step explanation:

The formula is y2-y1 over x2-x1.

(Remember that or another problem like that)

(3, 4) (-5,2)

x1 y1  x2 y2

We would do: 2-4 over -5-3

2-4=-2

-5-3=-8

Your answer would be: -2/-8, which is simplified to 1/4 because when you divide two negative numbers, you get a positive.

Answer:

2 days

Step-by-step explanation:

Step one:

let the number of days be x

and the total height be y

​Plant A is 6 cm tall and growing at a rate of 4 cm per day.

the total height is

y=6+4x------------1

Plant B is 10 cm tall and growing at a rate of 2 cm per day.​

y=10+2x-----------2

Required

time taken for both plants to have the same height

Step two:

equate the two equations to find when the plants will have the same height

6+4x=10+2x

collect like terms

4x-2x=10-6

2x= 4

divide both sides by 2

x= 4/2

x= 2 days

Answer:

50.2 cm^2

Step-by-step explanation:

Formula for the area of a circle: [tex]\pi r^{2}[/tex]

Radius of bigger circle = 5

Area of big circle = 25 * 3.14 = 78.5

Radius of smaller circle = 3

Area of small circle = 9 * 3.14 = 28.26

Now, we subtract:

78.5 - 28.26 = 50.24 <--- Because we have to round to the nearest tenth, the final answer is 50.2

Answer:

50.2 cm²

Step-by-step explanation:

Find the area of both circles and subtract them.

Step-by-step explanation:

[tex] \frac{2}{3} = \frac{30}{x} \\ 2x = 3(30) \\ \frac{2x}{2} = \frac{90}{2} \\ x = 45[/tex]

Answer:

Length = 15

Width = 6

Area = 90

Step-by-step explanation:

Area of the rectangle = [tex] {x}^{2} + 3x - 6x - 18[/tex]

Lets factorise the polynomial

[tex] = > x(x + 3) - 6(x + 3)[/tex]

[tex] = > (x + 3)(x - 6)[/tex]

We know that Area = Length × Width

Let the length be (x + 3) & width be (x - 6)

Its given in the question that x = 12. So putting the value of x gives ,

Length = [tex]x + 3 = 12 + 3 = 15[/tex]

Width = [tex]x - 6 = 12 - 6 = 6[/tex]

Area = Length × Width = 15 × 6 = 90
