The answer is s = d/t

Step-by-step explanation:

For question 12, I think this is called a literal equation, I might be wrong but I believe so it is a literal equation. They are asking you to get s on one side. And they are asking you what s is in terms of d and t. So what you do is, d = s x t. You multiply the t with the s and get d = st. Then you will divide t from both sides so, d/t = s/t, this will eliminate t from the s, and add it on to the d (distance). Which will leave you s on one side and d and t on the other. The answer is s = d/t.

Section 3

12) a) Here, as we need that s or speed is the subject so speed should be in place of distance. So, we get

s = d/t

Here, s is speed, d is distance and t is the time

12) b) We know that :

Average Speed = Total Distance/Total Time

Here, total distance is given 748 km

total time 11.5 hrs

Avg. Speed = 748/11.5

Avg. Speed = 65.04 km/h

Hence, the answer is 65.04 km/h

13) a) We know that volume of a rabbit hutch is

Volume of rabbit hutch = ½ × b × h × l

Here,

b is the breadth, h is the height and l is the length

Volume= ½ × 50 cm × 50 cm × 2.5 m

Now, here Length is in metre so we need to convert to cm

1 m = 100 cm

2.5 m = 2.5 × 100 = 250 cm

So, now

Volume= ½ × 50 cm × 50 cm × 250 cm

Volume = 50 cm × 50 cm × 125 cm

Volume = 312,500 cm³

Hence, the volume of this hutch is 312,500 cm³

13) b) Let us assume that the orange be a sphere

So, volume of orange = 4/3πr³

Here, r is the radius and π is pi

radius is 4 cm

Volume = 4/3π(4)³

Volume = 4/3 × 64π

Volume = 85.33π cm³

Volume of the orange is 85.33π cm³

3,750 deer

step-by-step explanation:

1,500 is 15 times larger than 100

lets make 250 15 times larger.

3750 deer

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
