A rectangular prism has the following dimensions. The base has sides that are 3 cm. and 5 cm. and the height is 9 cm. How many squares with 1 cm edges can cover the entire surface area of the prism completely with no overlaps?

Answers

Answer:

174 squares

Step-by-step explanation:

I would start by finding the surface area of the rectangular prism. You can use 2(wl+hl+hw).

2(wl+hl+hw)

2(3*5+9*5+9*3)

2(15+45+27)

2(87)

174 cm^2

The area of squares 1 cm edges would be 1 because 1*1=1, so you could find how many of them would fit on the surface area by dividing 174 by 1, which equals 174.

Answers

Answer:

4.1 -

300/22= 13.65

so the answer is 13.63

4.2

distance/speed

330/110= 3

So it'll take 3 hours

4.3

sorry not sure for this one :(

4.1

Cost of 22ltrs of petrol = Rs300

Cost of 1ltr of petrol = 300/22

= 150/11

= Rs13.63

4.2

distance = 330km = d

speed = 110km/hr = s

time = d/s

= 330/110

= 33/11

= 3hrs

4.3

SI = principal amount × rate of interest × time

[tex] = 2000 \times \frac{9}{100} \times 4[/tex]

[tex] = 20 \times 9 \times 4[/tex]

[tex] = 720[/tex]

Amount = Principal + SI

= 2000 + 720

= Rs2720

1. 3(x + 4) = 3(x - 5)
(could you please show work)

Answers

Use distributive property on both sides

3(x+4)=3(x-5)

3(x)+3(4)=3(x)-3(5)

3x+12=3x-15

Subtract 3x from both sides

12=15.

So because this is a false statement the equation has no solution. So your answer is no solution. Hope this helps!!!

Hamid has gained weight.
He now weighs 88kg, whish is higher than his normal weight
What is Hamid's normal weight?

Answers

The situation we have to find is how much weight Hamid has gained. There is no number so I’m just going to teach u how to find the original weight. So basically you have to subtract the weight that is gained from the current weight which will give you the answer to the normal weight.
Current weight-weight gained=normal weight
For example if he gained 5 kg
88-5=83 so his normal weight is 83kg
