Initial length = 72 cm

Stretched length = 90 cm

Find the increased in length:

increase = 90 - 72 = 18

Find the percentage increase:

Percentage increase = change/original x 100

Percentage increase = 18/72 x 100 = 25%

Answer: The elastic band's length is increased by 25%

Look at the triangular prism. Work out the volume of the prism.

xz_007 [3.2K]

Answer:

See explanation

Step-by-step explanation:

The question has missing details, as the diagram of the prism is not shown.

However, I'll solve using a general rule.

The volume of a triangular prism is:

$Volume = \frac{1}{2}* b * h * l$

Where

$b = base$

$h = height$

$l = length$

Take for instance:

$b = 20cm$

$h = 10cm$

$l = 5cm$

The volume is:

$Volume = \frac{1}{2} * 20cm * 10cm * 5cm$

$Volume = 10cm * 10cm * 5cm$

$Volume = 500cm^3$

Another instance (see attachment).

From the attachment:

$b = 4.5cm$

$h = 5cm$

$l = 8cm$

The volume is:

$Volume = \frac{1}{2} * 4.5cm * 5cm * 8cm$

$Volume = 2.25cm * 5cm * 8cm$

$Volume = 90cm^3$

Tyrell katy and lucy were eating grapes. Tyrell ate twice as many grape as katy, and lucy ate half as many grapes as katy. If ka

Vesnalui [34]

Answer:

21 grapes.

Step-by-step explanation:

We have been given that Tyrell ate twice as many grape as Katy. Lucy ate half as many grapes as Katy. Katy ate 6 grapes. We are asked to find the total number of grapes that all of them eat in all.

First of all, we will find twice of 6 grapes to find number of grapes eaten by Tyrell.

$\text{Grapes eaten by Tyrell}=2\times 6$

$\text{Grapes eaten by Tyrell}=12$

Now, we will find half of 6 to find number of grapes eaten by Lucy.

$\text{Grapes eaten by Lucy}=\frac{6}{2}$

$\text{Grapes eaten by Lucy}=3$

$\text{Grapes eaten by them in all}=6+12+3$

$\text{Grapes eaten by them in all}=21$

Therefore, the three of them eat 21 grapes in all.
