Answer:

3- 6 hours

4- 41 lbs

5- 53 dogs

Step-by-step explanation:

3. 480/24= 20

20= miles per hour

6 hours to travel 120 miles

4. 135/62= 2.18

2.18= cost of tomato per pound

90/2.18= 41.28 lbs or 41 lbs

3. 3/5=32/x

cross multiply

3x=160

divide both sides by 3

x=53.3 or 53

He should not have simplified 3/7 to 1/7 as they do not equal - he now has 2 less sevenths than before.

How many cubes with side lengths of 1/2 cm does it take to fill up the prism

ELEN [110]

24 cubes can filled up the prism

Solution:

The image of the question is attached below.

Given data:

Length of the prism = 2 cm

Breadth of the prism = 1 cm

Height of the prism = $$\frac{3}{2}$ cm

Volume of the prism = length × breadth × height

$$=2\times 1\times \frac{3}{2}$

$=3$ cubic cm

Volume of the prism = 3 cubic cm

Side length of the cube = $$\frac{1}{2}$ cm

Volume of the cube = side × side × side

$$=\left(\frac{1}{2}\right)^{3}$

$$=\frac{1}{8}$ cubic cm

Volume of the cube = $\frac{1}{8}$ cm

$$\text{Number of cubes} =\frac{\text{Volume of the prism}}{\text{Volume of the cube}}$

$$=\frac{3}{\frac{1}{8} }$

$=3\times8$

$=24$

Number of cubes = 24

Hence 24 cubes can filled up the prism.

Deffense [45]

L=length, w=width
l=2w+5
2l+2w=34
2l=4w+10 [here I just multiplied the first equation by two]
4w+10+2w=34 [substitute 4w+10 for 2l]
6w=24, w=4
remember l=2w+5 so l=2(4)+5=13

Answer: The length is 13.
