On Wednesday, Miguel's bank account balance was -$55. On Thursday, his balance was less than that. Use absolute value to describ
Juliette [100K]

In this situation, the -$55 represents the debt of $55, since this happens when Miguel does not have enough money in his account to cover payments or transactions. On Thursday, he has a debt of more than $55. The explanation behind this is if an account balance is less than -55 dollars, it exemplifies a debt bigger than 55 dollars.

You are making a recipe that calls for cream of mushroom soup. There is a deal at the store, where you can buy 10 cans of soup f
Olenka [21]

Answer:

The cost of 6 cans of soup =   $7.8

Step-by-step explanation:

The cost of 10 cans of soup = $13

The number of cans needed for the soup = 6

Now, Cost of 1 can of soup =\frac{\textrm{Total cost of 10 cans of soup}}{\textrm{10}}

= $13 / 10 =$1.3

⇒The cost of 1 can of soup is $1.3

Now, The cost of 6 cans of soup  =  6 x   Cost of 1 can

⇒ 6 x $1.3 =  $7.8

Hence, the cost of 6 cans of soup =   $7.8

Identify the theorem or postulate that is related to the measures of the angles in the pair, and find the unknown angle measures
aleksley [76]

Angles formed when two parallel are intersected by a common transversal include, corresponding, alternate interior and exterior, same-side interior, and vertically opposite angles

The correct option is Same–Side Int. ∠s Thm. m∠1 = 30°, m∠5 = 150°

The reason the selection is correct is as follows:

The given angles are;

m∠1 = (30·x - 30)°. m∠5 = (40·x + 70)°

∠1, and ∠5, are located on the same side of the transversal and are both formed on the interior side of the parallel lines

Therefore, they are same–side interior angles

Same side interior angles theorem states that same side interior angles formed between parallel lines are supplementary

Therefore, we have;

m∠1 + m∠5 = 180°

Which gives;

(30·x - 30)° + (40·x + 70)° = 180°

(70·x + 40)° = 180°

70·x = 180° - 40° = 140°

x = \dfrac{140^{\circ}}{70} = 2^{\circ}

m∠1 = (30·x - 30)° = (30 × 2 - 30)° = 30°

m∠1 = 30°

m∠5 = (40·x + 70)° = (40 × 2 + 70)° = 150°

m∠5 = 150°

The correct option is therefore;

Same-Side Int. ∠s Thm. m∠1 = 30°, m∠5 = 150°

Which expression can be written as k square root 3 where k is an integer
Damm [24]

Answer:

A simple expression is \sqrt{48} = 4\sqrt{3}

Step-by-step explanation:

Surds are irrational numbers expressed with respect to a square root. There are some basic rules required when dealing with surd.

Integers are numbers that do not have a decimal or fractional part i.e whole numbers. So, a simple expression that can be written as k square root 3 where k is an integer is \sqrt{48}.

So that,

                            \sqrt{48} = \sqrt{16 * 3}

                                   = 4\sqrt{3}
