Answer:
Step-by-step explanation:
substitute and solve:
100 = bh
100 = b(2b)
100 = 2b²
50 = b²
b = √50
b = √(25 * 2)
b = 5√2
solve for h:
h = 2b
h = 2(5√2)
h = 10√2
if you are told to round to 1 DP :
b ≈ 7.1 m
h ≈ 14.1 m
Answer:
where does 6 fit into the equation?
Step-by-step explanation:
<span>f(x) = 4x + 3
g(x) = -2x + 5
(f o g) (5) means the function of g when g is a function of 5
(the function of the function concept)
so we need to get g(5) firstly
</span>
<span>g(x) = -2x + 5
g(5)= -2(5) + 5 = -5
After that, f(g(5)) = f(-5) = 4(-5) + 3 = -20 + 3 = -17
I hope that helps

The quotient is 284 divided by 5, or
284
----- If you mult. numerator and denominator by 2, you get 578/10, or 57.8.
5
Try the numbers 550 and 600 (because 574 is between them). Now divide 550 and 600 by 10; the results will be 55 and 60. The actual value of 284/5 is between 55 and 60: 57.8 (which you can verify with a calculator).
Answer:
80%
Step-by-step explanation:
28/35 = 0.8
Divide. Convert a decimal to a percent by multiplying times 100.
0.8 × 100 = 80
Tara earned an 80%
You could use a calculator as described above or using mental math or pencil and paper:
28/35 = 4/5
Simplify.
4/5 = 8/10 = 80/100
Percent means per hundred, change 28/35 to hundredths as above.
Tara (still) gets an 80%.
