baby Dino = 15 paintings
Adult Dino = 7 paintings
Entire herd = 208 paintings
//Defining of Variables:
A = no. Of Adult
B = no. Of Baby
This is a simultaneous question so we’ll have to make up some equations.
3B = A —— (1)
This means there is 3x as many baby Dino as adult Dino
15B + 7A = 208 —— (2)
This means 15 paintings being painted by B number of babies + 7 paintings being painted by A number of Adults is 208 paintings.
Those are the equations we set.
Since we know A = 3B,
We can substitute A = 3B into (2).
As such:
15B + 7A = 208
15B + 7(3B) = 208
15B + 21B = 208
36B = 208.
We did that so that we only have 1 unknown variable so that we can calculate what is the value of a unknown variable, which in this case, is B.
If we furthur solve that equation above,
36B = 208
B = 5.777777777 ????
The reason why I was left with 5.77777777 amount of baby dinosaurs is because I didn’t know the value of the variables correctly as you didn’t state it clearly.
However, I’ve done the concept behind this question and I hope it helps you :)
If you would like me to solve it, could you please give me the values of the variables clearly?
Thanks, and have a good day ahead!
4x^5
You can get this because 4 is the largest number that goes into both of them. Also, you have the power of 5 in both of the terms.
F (5,9)
You would divide everything by 5 then 9 over 5
Answer:
Step-by-step explanation:
Step-by-step explanation:
the total surface area is the sum of the 5 individual areas in the surface :
2 triangle sides (left and right).
1 back rectangle side
1 rectangle floor
1 inclined rectangle front side
to get the length of the baseline (Hypotenuse) of the right-angled triangles on the side. we use Pythagoras
c² = a² + b²
where c is the Hypotenuse (the side opposite of the 90° angle).
c² = 3² + 4² = 9 + 16 = 25
c = 5
so, now, we have everything we need.
the area of a triangle side (since it is right-angled) :
4×3/2 = 6
2 sides, that makes 12
the area of the back side
6×3 = 18
the area of the floor
6×4 = 24
the area of the inclined front side
6×5 = 30
so, the total surface area is
12+18+24+30 = 84
