A model plane has a length of 26cm. The scale of the model is 1:50. Work out the length of the real plane. Give your answer in m

RideAnS [48]

1:50 means you do times 50 to get to real world size.

26 cm *50 = 1300 cm = 13 m

Find (f - g) (4) f(x) = 4x - 3 g(x) = x^3+2x a) 59 b) 85 c)-59 d) 285

fenix001 [56]

Answer: C). -59

Explanation:
F(x) = 4x -3
f(4) = 4(4) - 3 = 13
g(x) = x^3 + 2x
g(4) = 4^3 + 2(4) = 64 + 8 = 72
(F - g)(4) = 13 - 72 = -59

Sam and Kevin both worked hard over the summer. Together they earned a total of $425. Kevin earned $25 more than Sam.

Taya2010 [7]

Answer:

(a)

system of equations are

$s+k=425$

$k-s=25$

(b)

Graph is attached

(c)

Sam earned =$200

Kevin earned =$225

Step-by-step explanation:

Let's assume

's' for the amount Sam earned

'k' for the amount Kevin earned

(a)

Together they earned a total of $425

so, we get

$s+k=425$

Kevin earned $25 more than Sam

so, we get

$k=s+25$

so, system of equations are

$s+k=425$

$k-s=25$

(b)

now, we can draw graph

(c)

intersection point will be our solution

and we got intersection point as

(200, 225)

so,

s=200

k=225
