Answer:
A = 27 ft²
Step-by-step explanation:
A = 6*8 - 3*2 - 3*5
A = 48 - 6 - 15
A = 27
Answer:
On sale at a deficit of -20% from the original price is saying that the item is at 80% of its original value.
Converting percentages using decimals is a very easy way to fine original values.
So:
$76.80 = 80% of the original value
convert the 80% into a decimal = 0.80
The maths:
$76.80 ÷ 0.8 = $96.00
$96.00 = the original value.
Answer:
837.23 cm³
Step-by-step explanation:
La fórmula para el volumen de un prisma pentagonal se da como:
1/2 (5 s × a) × h
Dónde:
s = longitud lateral
a = Apotema
h = altura
De la pregunta anterior:
s = largo de lado = 6.1 cm
a = Apotema = 4.5 cm
h = Altura = 12.5 cm
Por lo tanto:
El volumen del prisma pentagonal =
1/2 (5 × 6.1 × 4.5) × 12.5
= 1/2 × 137.25 × 12.5
= 837.225 cm³
Aproximadamente = 837.23 cm³
1/8; say you have one whole pie, cut into fourths, than take one fourth, or one quarter, and cut that in half, it's the same as if you cut the whole pie in half than cut those halfs in half, making quaters, than cutting them in half, making a pie thats cut in eights, each slice is 1/8, one eight
Ok The volume of x is 2x+=3 hope this helps
