Why are decimals called decimals?

natta225 [31]

Answer:

Step-by-step explanation:

Decimal comes from the Latin word decimus, meaning tenth, from the root word decem, or 10. The decimal system, therefore, has 10 as its base and is sometimes called a base-10 system. Decimal can also specifically refer to a number in the decimal system.

Oh lord help q-q I have like no time left-

Answer:

(Triangular pyramid)

Lateral area = 1650 $m^{2}$

Total surface area = 1860.1 $m^{2}$

(Triangular prism)

Volume = 660 $cm^{3}$

Step-by-step explanation:

For the triangular pyramid

Area of triangle = $\frac{1}{2}$ × base × height

Area of the base = $\frac{1}{2}$ × 22 × 19.1 = 210.1

Area of the sides = $\frac{1}{2}$ × 22 × 50 = 550

Number of sides (excluding base) = 3

∴ Total Area = 210.1 + (550 × 3)

= 210.1 + 1650 = 1860.1 $m^{2}$

Lateral Area = (550 × 3) = 1650 $m^{2}$

For the triangular prism

Area of the triangle = $\frac{1}{2}$ × 12 × 5 = 30

Volume = Area x Height

Volume = 30 × 22 = 660 $cm^{3}$

When 25 is added to a number the result is 59 less than 4 times the number.

marin [14]

X - the number

The expression:
$x+25=4x-59$

The solution:
$x+25=4x-59 \\
x-4x=-59-25 \\
-3x=-84 \\
x=\frac{-84}{-3} \\
x=28$

The number is 28.

denis-greek [22]

It percent must be a 100%. So if she knows that 72% students choose a mascot, then take 100% subtract 72% you'll get 28%. Which mean the other 28% of the student will choose a Viking as their mascot.
