Answer:

32

Step-by-step explanation:

let a = 5

a² + 7 | Original equation

5² + 7 | Substitution of a as 5

25 + 7 | 5 to the power of 2 is 25, as 5*5 = 25.

32       | 25 + 7 = 32

The height & speed are mathematically given as

t = 0.2 s

u = 4 m/s

<h3>What is the height & speed?</h3>

Generally, the equation for height is  mathematically given as

h = 0.2gt^2

Therefore

0.2 = 0.5 * 9.8 *t^2

0.2 = 4.9 *t^2

t = 0.2 s

b)

In conclusion, the initial speed is

s = ut

Therefore

u = 0.8 / 0.2

u = 4 m/s

Nicholas has a larger tropical fish collection. He gives 2/3 of his fish to a high school. Then he gives 2/5 of the remaining fi
Kitty [74]
Let the initial count of his fish be n.

He gives away 2/3 of these fish:  2n/3, leaving n/3 fish.

He gives away 2/5 of these remaining n/3 fish:  (2/5) times (n/3), or 

2n
--- , meaning that (3/5) times (n/3) fish are left.
15

(3/5)(n/3) = n/5 fish left = 30 fish.  Thus, n = 150 fish.

Edgar Anderson earns $300 per week plus 15% commission on all sales over 1,000. if Mr. Anderson's sales for one week are 2,500 w
vredina [299]
Since he only makes commission on sales over $1000, he makes commission on $1500 (we find this by doing 2500-1000.) His commission is 15%, so find 15% of $1500:
.15*1500=225
So we know how makes $225 in commission.

Now we need to add this to his fixed pay to get his total pay:
225+300=525
So his total pay is $525, which is answer 'a' 

Hope I helped, and let me know if you have any questions :)

Choose an equivalent system of equations to the following system:
andrezito [222]

Answer:

B.  6Fx + 6Gy = 6H

    Qx + Ry = S

Step-by-step explanation:

Equivalent equations can be created many ways. One of the simplest is to multiply both sides of the equation by the same number. In the answer above, the first equation has been multiplied by 6. Nothing has been done to the second equation.

_____

<em>Comments on other choices</em>

A: some terms have been multiplied by 6. This changes the equation(s) so they are no longer equivalent to the ones you started with.

B: the correct choice

C: see A.

D: the first equation has been multiplied by 6, so that is equivalent to the original. The second equation has the sign of one of the terms changed, so it is now a different equation.
