Answer:

n = 199

Step-by-step explanation:

Actually, your task here is "Solve for n: "

Starting with n+ -741 = -542, add 741 to both sides, obtaining n = 199

N=199 because in order to get a a smaller negative you would have to add a positive into a negative

Pyramide-shaped gift boxes have square bases that measure 5 inches on each side.The slant height is 6.5 inches.How much cardboar

andrew-mc [135]

1. square base area= 25 inches

2. using the slanted 6.5
=1/2base , therefore 5/2=2.5 inches

3. then use pythagoras.... c=6.5, a=2.5
c^2=a^2 + b^2
(do this urself)

4. when u find what b is... that's the height of one of the triangle
base= 2.5 (look at step 2 if u don't understand this bit)
height=b (refer to step 3)

5. then work out the area of 1 triangle using that...
6. then have (the answer u work out in step 5 ) multiply 4
this will give u the area for the all of the 4 triangles...

7. Then add together the square based area in step 1..(25)
to the 4 triangular, area faces (i.e from step 6) - the total will be ur answer for the amount of cardboard!!

p.s don't forget the units!!!

68 1/4% as a decimal

eduard

Answer: The correct answer is: " 0.6825 ".

_______________________________________________

Step-by-step explanation:

_______________________________________________

We are asked to convert: " 68 $\frac{1}{4}$ % " ; to a "decimal" .

_______________________________________________

1) Rewrite: " 68 $\frac{1}{4}$ " ; as a "decimal value" :

" 68 $\frac{1}{4}$ " = 68 + $\frac{1}{4}$ ;

→ " $\frac{1}{4}$ " = 1 / 4 = 1 ÷ 4 = 0.25 . (use calculator).

Or: → " $\frac{1}{4}$ " = " $\frac{?}{100}$ " ;

→ Find the "?" value:

_______________________________________________

Let us consider the "denominators" ;

→ 4 * (what value) = 100 :

→ 100/ 4 = 100 ÷ 4 = 25 .

So: 4 * 25 = 100;

So, to find the "?" value in the numerator:

→ 1 * 25 = ("?") ;

→ 1 * 25 = 25 ;

_______________________________________________

So, we have:

_______________________________________________

→ " $\frac{1}{4}$ " = " $\frac{?}{100}$ " ;

Rewrite; and replace the "?" value with our know value: " 25 " :

→ " $\frac{1}{4}$ " = " $\frac{25}{100}$ " ;

Note that: " $\frac{25}{100}$ " ;

= 25/100 = 25 ÷ 100 = 0.25 . {Use calculator.}.,

Or: 25 ÷ 100 = ? ;

→ When dividing by "100" ; we take the number; and move the decimal point back 2 (two) spaces; since "100" has 2 (two) zeros.

→ 25 ÷ 100 = 25. ÷ 100 = .25;

→ write as: " 0.25" .

_______________________________________________

So: " 68 $\frac{1}{4}$ " = 68 + 0.25 = 68.25 .

As such: " 68 $\frac{1}{4}$ % " = 68.25 % ;

_______________________________________________

Now, we write: " 68.25 % " as a decimal ;

<u>Note</u>: " % " ; or "percent" ; means "per hundred" ; or "parts per hundred" ;

or; "divide by 100" ;

_______________________________________________

So; to write: " 68.25 % " as a decimal ;

→ " 68.25 ÷ 100 " = 0.6825 . {← Use calculator.}.

Or: → 68.2 ÷ 100 = ? ;

→ When dividing by "100" ; we take the number; and move the decimal point back 2 (two) spaces; since "100" has 2 (two) zeros.

→ " 68.25 ÷ 100 " ÷ 100 = .6825 ;

→ write as: " 0.6825 " .

_______________________________________________

The answer is: " 0.6825 " .
