Answer:
- 439
Step-by-step explanation:
- s ( x ) = 2 - x²
- t ( x ) = 3x
- s ( t ( -7 ) ) = ?
--------------------------
- t (-7) = 3 * ( -7 ) = -21
- s ( t ( -7 ) ) = s ( -21 ) = 2 - ( -21 )² = 2 - 441 = - 439
- s ( t ( -7 ) ) = -439
Answer:
Number 2 is 3:4.
Number 1 is d.
Step-by-step explanation:
Boxers and collies added together gives you 12:16. Divide them both by 4 and you get 3:4.

The number of student in class 4 (6) divided by the total number of kids in the entire class (18) gives you 0.33333333333. Multiply that by 100 and it gives you 33.3333333333. As a percentage it is 33 1/2 %
The whole number multiply by the denominator and add to the numerator.
Answer:


And we got finally:

And the amount for Zaid would be 1.2*360 ft= 432ft
So then Zaid construc 432 ft and Matias 360 ft
Step-by-step explanation:
For this case we know that Zaid and Matias, two farmers, constructed a 792 foot fence around their very large garden so then the total is represented by 792 ft
We also know that Zaid agreed to construct 20% more of the fence than Matias did. Let's assume that the amount that construct by Matias was x then the amount constructed by Zaid would be 1.2 x representing 20% more than Matias and we can set up the following equation:


And we got finally:

And the amount for Zaid would be 1.2*360 ft= 432ft
So then Zaid construc 432 ft and Matias 360 ft
Answer:
We have to choose any one from option B and option C
Step-by-step explanation:
We have to perform a subtraction of two decimal numbers.
(9.43 - 4.286) = (9.430 - 4.286) = 5.144.
Hence, the answer is 5.144 which is given both options B and C.
In case there are two options with the same value and the value is the answer, then you choose any one of them but not both.
Here in our case, we have to choose any one from option B and option C and we will be rewarded full marks. (Answer)
