Answer:
15/16.
Step-by-step explanation:
2 1/2 = 5/2 and 2 2/3 = 8/3 so we have:
5/2 / 8/3 Invert the 8.3 and multiply:
= 5/2 * 3/8
= 15/16.
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
The product of <span>2 3/8 x 1/3 will be found as follows:
We convert the first term into proper fraction
2 3/8=(2*8+3)/8=19/8
multiplying we get:
19/8</span>×1/3
=19/24
Y = total costs to get the berries
x = pounds of berries.
bearing in mind that the $5 is just to get in, so is only paid once, whilst the pounds of berry will vary.
Answer:
C,20%
Step-by-step explanation:
First we are told that she has 3 hours to grade 35 student papers ,and she has 30 minutes to grade 5 paper, now we calculate how long it took her to grade 1 paper.
Part1
if 5papers = 30minutes
therefore 1paper = (30*1)/5 = 6mins per paper.
now we are left with 2hrs 30mins(150 mins) to grade 30papers
Part2
if 30papers = 150minutes
therefore 1paper = (150*1)/30 = 5mins per paper.
to calculate how fast she has to be in relation to the first part
we substract :
(6mins- 5mins)/ 5mins *100 =1/5 * 100 = 20%.
