A particular shoe store stocks two styles of walking shoes. Style A sells for $66.95 and Style B sells for $84.95. At the end of

Gnom [1K]

Answer:

Style A shoes sold : 152

Style B shoes sold : 88

Step-by-step explanation:

Let :

Style A shoes = x
Style B shoes = y

Forming equations :

x = 2y - 24
66.95x + 84.95y = 17,652

Substitute the value of x from 1 in 2.

66.95 (2y - 24) + 84.95y = 17,652
133.90y - 1606.80 + 84.95y = 17,652
218.85y = 19258.80
y = 88

Finding x :

x = 2(88) - 24
x = 176 - 24
x = 152

Solution :

Style A shoes sold : 152
Style B shoes sold : 88

The stock market dropped 220 points on Monday. It lost another 48 points on Tuesday, and on Wednesday, it gained 96 points. What

Leona [35]

Answer: 48 points gained in those 3 days.

Subtract 220 with 48, then add 96. Last step would be subtracting 220 with the amount they have now in those 3 days to find how much points the stock market gained in those 3 days.

Subtract 220-48.It‘ll be 172.

Add 172 with 96. 172+96=268.

Subtract 268 with how much points the stock market had 3 days ago. 268-220. So it would be about 48 points gained.

Question in attachment

Damm [24]

Answer:

a) scale factor = 1.5

b) d length is 7.5

c) Area scale factor is 2.25

Step-by-step explanation:

Given QR =6

And ST =9

Length Scalar factor = enlarged length /previous length

=9/6

=1.5

Length Scalar factor =1.5

b)we know PS enlarged length of PQ

Length scale factor = PS/PQ

1.5 =PS/5

PS =5×1.5

PS =d =7.5

d length is 7.5

c)Formula :

Area scale factor = (length scale factor)2

=(1.5)2

=2.25

Area scale factor is 2.25

Jane wishes to bake an apple pie for dessert. The baking instructions say that she should bake the pie in an oven at a constant

Viktor [21]

Answer:

Therefore $k= \frac{ln2 }{18}$ , A=184

Step-by-step explanation:

Given function is

$T(t)=230 -e^{-kt}$

where T(t) is the temperature in °C and t is time in minute and A and k are constants.

She noticed that after 18 minutes the temperature of the pie is 138°C

Putting T(t) =138°C and t= 18 minutes

$138=230 -Ae^{-k\times 18}$

$\Rightarrow -Ae^{-18k}=138-230$

$\Rightarrow Ae^{-18k}=92$ .....(1)

Again after 36 minutes it is 184°C

Putting T(t) =184°C and t= 36 minutes

$184=230-Ae^{-k\times 36}$

$\Rightarrow Ae^{-36k}=230-184$

$\Rightarrow Ae^{-36k}=46$ .......(2)

Dividing (2) by (1)

$\frac{Ae^{-36k}}{Ae^{-18k}}=\frac{46}{92}$

$\Rightarrow e^{-18k}=\frac{46}{92}$

Taking ln both sides

$ln e^{-18k}=ln\frac{46}{92}$

$\Rightarrow -18k =ln (\frac12)$

$\Rightarrow -18k= ln1-ln2$

$\Rightarrow k= \frac{ln2 }{18}$

Putting the value k in equation (1)

$Ae^{-18\frac{ln2}{18}}=92$

$\Rightarrow A e^{ln2^{-1}}=92$

$\Rightarrow A.2^{-1}=92$

$\Rightarrow \frac{A}{2}=92$

$\Rightarrow A= 92 \times 2$

⇒A= 184.

Therefore $k= \frac{ln2 }{18}$ , A=184
