Help with any of the questions what be appreciated

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

i think that you should ask google for the answer to that problem because if we don't know it google does

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
