Tyana has a collection of hoodies and t-shirts. She has 561 pieces of collected clothing in all. The number of hoodies is twice

Delicious77 [7]

Answer:

187 t-shirts and 374 hoodies.

Step-by-step explanation:

(t is shirts)

561 = t + (2t)

561 = 3t

/3. /3

187 = t

ck:

187 + ( 2 times 187) = 561

187 + 374 = 561

561 = 561

The first equation, 8x - 9y = - 23

Obtain the equation in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = ( $\frac{1}{2}$ , 3) and (x₂, y₂ ) = (- 4, - 1 )

m = $\frac{-1-3}{-4-1/2}$ = (- 4)/- $\frac{9}{2}$ = $\frac{8}{9}$

partial equation is y = $\frac{8}{9}$ x + c

to find c substitute either of the 2 points into the partial equation

using (- 4, - 1 ), then

- 1 = - $\frac{32}{9}$ + c ⇒ c = $\frac{23}{9}$

y = $\frac{8}{9}$ x + $\frac{23}{9}$ ← in slope- intercept form

the equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

rearrange the slope- intercept equation into this form

multiply through by 9

9y = 8x + 23 ( subtract 9y and 23 from both sides )

8x - 9y = - 23 in standard form

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.
