What is the absolute value of -12.5

Vladimir [108]

The absolute value of -12.5 is?

|-12.5| = 12.5

The absolute value of a negative number is the number that is exactly opposite on the number line, being a positive number. A positive number's absolute value is always the same thing, positive. Examples:-

|10| = 10
|-10| = 10
|-8.5| = 8.5
|8.5| = 8.5

|-12.5| = 12.5

${\bold{\red{\huge{\mathbb{QUESTION}}}}}$

what is the average cost of 7 articles if 3 of them cost 30k each and the rest cost 12.5k each

$\bold{ \red{\star{\blue{GIVEN }}}}$

TOTAL NUMBER OF ARTICLE= 7

ARTICLES FOR 30K = 3

ARTICLES FOR 12.5K = 7-3= 4

$\bold{\blue{\star{\red{TO \: \: FIND}}}}$

Average cost of 7 articles

$\bold{ \green{ \star{ \orange{FORMULA \: USED}}}}$

$\red{AVERAGE = \frac{TOTAL \: COST}{ NUMBER \: OF\: ARTICLES }}$

Answer:

See Explanation

Step-by-step explanation:

Given

$\triangle ABC = \triangle DE F$

Required

Which would not prove the similarity

$\triangle ABC = \triangle DE F$ implies that:

The following angles are congruent

$\angle A = \angle D$

$\angle B =\angle E$

$\angle C =\angle F$

And the following lengths are congruent

$AB = DE$

$BC =EF$

$CA = FD$

The options are not clear; so, it's a bit difficult to select the correct option.

<em>Any of the options that is different from the above list of 6 congruent pairs is the answer to your question.</em>

Four families each brought the same number of chairs to a block party. Three more chairs are needed to seat all 27 people how ma

Olin [163]

Hi! :)

This question states that four families each brought the same number of chairs. We know that 27 chairs are needed overall and 3 are still needed after the four families' contributions.

Knowing this, you can figure out that you could do 27-3. This equals 24, so you would then just divide 24 by 4, since there are 4 families.

Your final answer should be that each family brought 6 chairs.

Hope this helps!
