Answer:

5.45 hours.

Step-by-step explanation:

The formula =

P = P0(10)t

In this circumstance, P0 = 275, P = 15,000 and t = ?

Applying the values into the formula:

P = P0(10)t

15,000 = 275 × (10) × t

15,000 = 2750t

t = 15,000/2750

t = 5.45 hours

Find the value of x 12x 6x+28 Your answer

Irina18 [472]

Step-by-step explanation:

Hey there!

By looking at the figure, the given "2x" and "6x + 28" are co-interior angle.

So,

2x + 6x + 28 = 180°. ( sum of co-interior angle is 180°)

8x + 28°=180°

8x = 180° - 28°

8x = 152°

$x = \frac{152}{8}$

X = 19°

Therefore, X = 19°.

Hope it helps...

4. At a school fair, 30% of the pies sold had cheese filling, 25% had beef filling and the remaining 90 pies had potato filling.

astra-53 [7]

Answer:

Step-by-step explanation:

a) Percentage of potato filling = 100 - (30 + 25) = 100 - 55 = 45 %

b) Let the number of pies sold = x

45% of x = 90

$\dfrac{45}{100}*x=90\\\\\\x=90*\dfrac{100}{45}\\\\\\x=2*100\\$

Number of pies = 200

c) Number of cheese filling = 30% of 200

$=\dfrac{30}{100}*200\\\\= 30*2\\\\\\= 60$

Number of beef pies = 25% of 200

$=\dfrac{25}{100}*200\\\\\\=25*2\\\\= 50$

Difference = 60 - 50 = 10

There are 10 more cheese pies than beef pies.
