Answer:

The answer is 1/12

Step-by-step explanation:

Step 1: To multiply the fractions, multiply the numerators and denominators separately.

1*1 and 3*4

Step 2: That becomes 1 over 3*4

Step 3: 3 times 4 is 12, therefore your answer is 1/12

Which of the following pairs of numbers has a GCF of 1? 30 and 70 24 and 44 12 and 30 16 and 21

stiv31 [10]

Must be 16 and 21 because we can see

30 and 70 has 10 as factor
24 and 44 has 2 as factor
12 and 30 has 2 as factor and all those factors are greater than one

Which equations are true for x = –2 and x = 2? Select two options x2 – 4 = 0 x2 = –4 3x2 + 12 = 0 4x2 = 16 2(x – 2)2 = 0

Svetllana [295]

The equation $x^{2} -4=0~~and~~4x^2=16$ are true for x = -2 and x = 2.

The given equations are given as:

$x^2-4=0\\\\x^2=-4\\\\3x^2+12=0\\\\4x^2=16\\\\2(x-2)^2=0$

We need to select two equations that are true for x = -2 and x = 2.

<h3>What are the solutions to an equation ?</h3>

The solutions of an equation are the values that satisfy the given equation or make the equation true when substituted for unknowns in the equations.

Example:

x - 2 = 2

Here the solution for x - 2 = 2 is 4 because x = 4 will make the equation true.

4 - 2 = 2

2 = 2

Let's find the solutions for each equation.

$x^2 - 4=0$

$x^{2}$ = 4

x = $\sqrt{4}$ = ± 2

x = = 2 and x = -2

$x^2 =-4$

x = $\sqrt{-4}$

x = $\sqrt{-1 \times 4}$ = $\sqrt{-1}\times\sqrt{4}$

x = ± 2 $\sqrt{-1}$

x = 2i and x = -2i where i = $\sqrt{-1}$

3 $x^{2}$ + 12 = 0

$x^{2}$ = -12 / 3 = -4

x = $\sqrt{-1}$ $\sqrt{4}$

x = ± 2 $\sqrt{-1}$

x = 2i and x = -2i

4 $x^{2}$ = 16

$x^{2}$ = 16 / 4

$x^{2}$ = 4

x = $\sqrt{4}$

x = ±2

x = 2 and x = -2

$2(x-2)^2 = 0$

$(x-2)^2 = 0$

x - 2 = 0

x = 2.

Thus the equation $x^{2} -4=0~~and~~4x^2=16$ have solutions x = -2 and x = 2.

A chief makes one 1 1/2 gallons of soup in a large pot how many one cup servings can the chief get from this large pot of soup

Elenna [48]

So,

We need to convert from gal. to c.

16 c. = 1 gal.

$16 * 1 \frac{1}{2} = 16 * \frac{3}{2}$

24 cups

The chef can get 24 cups of soup from his pot.
