How many angles does a cube have?

Answers

A cube is a geometric three-dimensional solid object. It constitutes 6 square faces, sides and three meeting at each vertex. It is the only regular hexahedron. A cube has a fixed number of perpendicular angles. Typically, it has 8 perpendicular angles and each spigolo or corner has 3 angles. Since it has 8 perpendicular (⊥) angles and 3 angles in each corner, it makes up 24 angles.
All 8 ⊥ angles and 3 angles in each corner mean: 8*3=24.

Therefore, a cube has 24 right angles.

A Pairs socks that normally sells for eight dollars is on sale for 15% off find the sale price of the socks then find the total cost of the jeans if the sales tax rate is 8%

Answers

Answer:

Step-by-step explanation:

The original selling price of the pair of socks is $8. The pair of socks is on sale for 15%. The new selling price of the pair of socks would be the original price - 15% off the original price. It becomes

8 - (15/100 × 8) = 8 - 0.15×8 = 8 - 1.2 = $6.8

if the sales tax rate is 8%, it means that the total cost of the socks would be the new selling price + 8% of the new selling price. It becomes

Total cost of the pair of socks

= 6.8 + (8/100×6.8) = 6.8 + 0.08×6.8 = 6.8 + 0.544 = $7.344

Maria is comparing the prices of two window cleaning companies. Company A charges $6 per window and an additional $12 as service charges. Company B charges $5 per window and an additional $15 as service charges. Part A: write equations to represent Company A's and Company B's total charges for cleaning number windows. Define the variable used in the equations.

Part B: which company would charge less for cleaning 8 windows? Justify your answer.

Part C: How much money is saved by using the services of Company B instead of Company A to clean 6 windows?

Answers

Part A
Company A: c=6w+12
Company B: c=5w+15
c=cost w=# of windows
Part B
Company A: c=6(8)+12 c=$60
Company B: c=5(8)+15
c=$55
So Company B is the cheaper option by 5 dollars.

Part A:
y is how much they charge in total
x is the amount of windows
Company A is (6*x)+ 12= y
Company B is (5*x)+15=y

Which expression gives the same result as ∑4i=0(5)(1/3)i

Answers

I'm assuming which expression gives the same result as ∑^4
The choices are:
i=0^(5)
(1/3)^i

The second option is correct since the first option is erroneous or makes little sense. The second option and the ∑^4 are geometric progressions which will account for each other when substituted together or one into another.

How to write 25/4% as a decimal

Answers

First let's reduce 25/4

25/4 = 6 1/4

Now we can convert 1/4 to hundredths

6 1/4 = 6 25/100

Now just rewrite 25/100 according to place value (twenty-five hundredths is .25)

6 25/100 = 6.25

Now don't forget we are still in percentage (25/4% = 6.25%)

convert to decimal by dividing by 100 ( move decimal 2 places to the left).

6.25% = .0625

To write 25/4 as a decimal you have to divide numerator by the denominator of the fraction.
We divide now 25 by 4 what we write down as 25/4 and we get 6.25
And finally we have:
25/4 as a decimal equals 6.25
