Answer:

10t³ - 95t + 45

Step-by-step explanation:

Plug the g(t) and h(t) into the equation: (3(3t - 3) - 2(t³ - 5t)) (-5)

Distribute 3 & -2 through the prentheses : (9t - 9 2t³ + 10t) (-5)

Collect like terms : (19t - 9 - 2t³) (-5)

Distrubute -5 through the parentheses: -95t + 45 + 10t³

Use the commutative property to reorder the terms : 10t³ - 95t + 45

Solution : 10t³ - 95t + 45

An electric bulb is sold in a box measuring 5 cm by 4 cm by 4 cm. If the shopkeeper receives them in a carton measuring 50 cm by

katen-ka-za [31]

Answer:

250

Step-by-step explanation:

Bulb box and carton both are of cuboidal shape.

For bulb box the dimensions are:

l = 5 cm, w = 4 cm, h = 4 cm

$V_{Bulb\: box} =lwh$

$\implies V_{Bulb\: box} =5(4)(4)$

$\implies V_{Bulb\: box} =80\: cm^3$

For Carton the dimensions are:

l = 50 cm, w = 20 cm, h = 20 cm

$V_{Carton} =lwh$

$\implies V_{Carton} =50(20)(20)$

$\implies V_{Bulb\: box} =20,000\: cm^3$

To find the number of bulbs packed in the carton, divide the $V_{Carton}$ by $V_{Bulb\: box}$

$Number \:of \:bulbs =\frac{V_{Carton}}{V_{Bulb\: box}}$

$\implies Number \:of \:bulbs =\frac{20,000}{80}$

$\implies Number \:of \:bulbs = 250$

So, 250 bulbs will be packed in one carton.

Solve equation. 2x-5y=20

Novay_Z [31]

If you solve for x you get:
x=(5/2)y+10

If you solve for y you get:
y=(2/5)x−4
