Anna71 [15]

Tank A capacity = 550 gallons 66% x 550 gallons = 363 gallons in Tank A

How about the water in tank B?

ratio of 11: 15 11/15 = 550/x 550 * 15/11 = cap B = 750 gal 53% 0f 750 = .53 x 750 = 397.5 gal in tank B

zalisa [80]

Answer:

Mistake in Line 2

Step-by-step explanation:

Line 1

7(6) ÷ 5 + 42

Line 2

7(6) ÷ 5 + 16

Line 3

42 ÷ 5 + 16

Line 4

42 ÷ 21

Line 5

To simplify any expression we use order of operation

Line 1 is 7(6) ÷ 5 + 42

Order of operation is PEMDAS

First we start with parenthesis

so we multiply 7(6) in line 2

7*6- 42

So Line 2 is 42 ÷ 5 + 42

Hence there is a mistake in Line 2

Hey how do you get from standard form to vertex form?

vlabodo [156]

Explanation:

Conversion of a quadratic equation from standard form to vertex form is done by completing the square method.

Assume the quadratic equation to be $\mathbf{ax^{2}+bx+c=0}$ where x is the variable.

Completing the square method is as follows:

send the constant term to other side of equal $\mathbf{ax^{2}+bx=-c}$
divide the whole equation be coefficient of $\mathbf{x^{2}}$ , this will give $\mathbf{x^{2}+\frac{b}{a}x=- \frac{c}{a}}$
add $\mathbf{(\frac{b}{2a})^{2}}$ to both side of equality $\mathbf{x^{2}+2\times\frac{b}{2a}x+\frac{b}{2a}^{2}=-\frac{c}{a}+\frac{b}{2a}^{2}}$
Make one fraction on the right side and compress the expression on the left side $\mathbf{(x+\frac{b}{2a})^{2}=\frac{b^{2}-4ac}{4a^{2}}}$
rearrange the terms will give the vertex form of standard quadratic equation $\mathbf{a(x+\frac{b}{2a})^{2}-\frac{b^{2}-4ac}{4a}=0}$

Follow the above procedure will give the vertex form.

(NOTE : you must know that $\mathbf{(x+a)^{2}=x^{2}+2ax+a^{2}}$ . Use this equation in transforming the equation from step 3 to step 4)

15. Which set of numbers forms a Pythagorean triple?

dusya [7]

Answer:

11, 60.61

Step-by-step explanation:

this is the only set that fits a^2 +b^2=c^2

you square the first two numbers, add them together. Then you take the square root of that sum. This number must equal the third number for it to be a triple.
