Answer:

Step-by-step explanation:

1) ∠1 + ∠2 = 180 {linear pair}

105 +∠2 = 180

∠2 = 180 - 105

∠2 = 75°

Reason: Linear pair

2) ∠3 = ∠1 {Vertically opposite angles are congruent}

∠3 = 105

Reason: Vertically opposite angles are congruent

What ratio is less than 15:24.these are the answer choices > 1:2, 7:8, 19:24, 6:8

Drupady [299]

15:24 is divisible by 3, simplifying it down to 3:8. 19:24, 7:8, and 6:8 are all obviously larger than this ratio, and 1:2 can be equalized to 4:8, which is also bigger than 3:8, so none of the answer choices are less than 15:24.

Let A = {x : 2x² + 3x - 2 = 0} and B = {x : x² + 3x - 4 = 0 } find (A U B) × (A Π B)

ivann1987 [24]

Given :

A = {x: 2x² + 3x - 2 = 0 }
B = {x : x² + 3x - 4 = 0 }

To find :

(A U B ) × (A Π B )

Solution :-

The first set is ,

A ={x : 2x² + 3x - 2 = 0}

Solving the Quadratic equation ,

2x² + 3x - 2 = 0
2x² + 4x - x - 2 = 0
2x( x + 2) -1( x + 2 ) = 0
(2x -1) ( x + 2) = 0
x = 0.5 , -2

Hence ,

A ={0.5, -2}

The second set is ,

B ={ x :x² + 3x - 4 = 0 }

Solving the Quadratic equation ,

x² + 3x - 4 = 0
x² + 4x - x - 4 = 0
x( x + 4)-1 ( x +4) = 0
(x + 4) ( x -1) = 0
x = 1 , -4

Hence ,

B ={1,4}

Now ,

A U B = { 0.5 , 1 , 4 , -2}
A Π B = {∅ }

Since AΠ B is a null set , hence ,

A × B = {∅}

Answer:

$\sf 2\dfrac{1}{4}\ cups \ of \ sugar$

Explanation:

Let the full batch be x

Here given:

3/4 cup of sugar required to make 1/3 batch of cookies

Build equation:

$\sf \rightarrow \dfrac{1}{3}x = \dfrac{3}{4} \ cup \ of \ sugar$

Solve:

$\sf \rightarrow x = \dfrac{3(3)}{1(4)}$

$\sf \rightarrow x = \dfrac{9}{4}$

$\rightarrow \sf x = 2\dfrac{1}{4}$
