Answer:

Height h = 9 cm

Step-by-step explanation:

Given:

Surface area of cuboid = 102 cm²

Length l = 2 cm

Breadth b = 3 cm

Find:

Height h

Computation:

Surface area of cuboid = 2[lb + bh + hl]

102 = 2[(2)(3) + (3)(h) + (h)(2)]

51 = 6 + 3h + 2h

45 = 5h

Height h = 9 cm

There is an animal farm where chickens and cows live. All together, there are 84 heads and 210 legs. How many chickens and cows
Ira Lisetskai [31]

1 Chicken have = 2 legs

1 Cow have = 4 legs

No of cows = x

No of chickens = y

Total no of legs = 4x + 2y = 210.............(1)

Total No of heads = x + y = 84................(2)

x = 84 - y....( from (2) )

Substituting the above equation in (1)

4 ( 84 - y) + 2y = 210

336 - 4y + 2y = 210

336 - 2y = 210

-2y = -126

= y = 63

No of cows = 84-63 = 21

∴ <u><em>Total no of cows = 21</em></u>

<u><em>Total no of chickens = 63</em></u>

Verizon [17]

Answer:

148 minutes

Step-by-step explanation:

It is 3{:}32\text{ p.M.}3:32 p.M.3, colon, 32, start text, space, p, point, m, point, end text and Emma has gymnastics lessons at 6{:}00\text{ p.M.}6:00 p.M.6, colon, 00, start text, space, p, point, m, point, end text How many minutes are there until Emma's gymnastics lessons?\

The time is 3:32 pm

Emma's gymnastics lesson is at 6:00 pm

6:00 pm - 3:32 pm = 2 hours 28 minutes

That is, we have 28 minutes before 4:00 pm

And 2 hours from 4:00 pm to 6:00 pm making a total of 2 hours 28 minutes

How many minutes are there until Emma's gymnastics lessons?

Convert 2 hours 28 minutes to minutes

1 hour = 60 minutes

2 hours = 60 minutes × 2 = 120 minutes

120 minutes + 28 minutes = 148 minutes

2 hours 28 minutes to minutes = 148 minutes
