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:

-106, -104, -102

Answer:

B and C

Step-by-step explanation:

[tex]56 - ( {3}^{3} + 13) = 16[/tex]

For A

[tex] \frac{92 - (12 + 16)}{4} = 16 \\ [/tex]

For B

[tex] {6}^{2} \div 4 + 5 = 14[/tex]

For C

[tex](6 \times 7) + 3 + 2 = 47[/tex]

For D

[tex]19 \times 4 - {8}^{2} + 4 = 16[/tex]

Here, B and C have not same value

Answer:

92

Step-by-step explanation:

for each sale, the number of tokens increases by a pattern from 1 sale to 2, the tokens increase by 7. next by 9. next by 11. if this pattern continues, by eaight sales the number of tokens will be 92 tokens

5 -41 tokens

6 - 56 tokens

7 - 73 tokens

8 - 92 tokens

this is my best guess at the problem, if you aren\t working with sequences then this is probably wrong

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

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:

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

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.
