Sela is making 400 scones.
7nadin3 [17]

Answer:

£15.20

Step-by-step explanation:

butter : sugar : flour = 2 : 1 : 9

Total mass for 1 recipe = 30 g

2 + 1 + 9 = 12

12x = 30

x = 30/12

x = 2.5

For 1 scone:

butter = 2x = 2(2.5) g = 5 g

sugar = x = 2.5 g

flour = 9x = 9(2.5) g = 22.5 g

Cost for 1 scone:

butter: 5 g × £2.50/(500 g) = £0.025

sugar: 2.5 g × £1.60/(1000 g) = £0.004

flour: 22.5 g × £0.6/(1500 g) = £0.009

Cost for 1 recipe = £0.025 + £0.004 + £0.009 = £0.038

Cost for 400 scones = 400 × £0.038 = £15.20

Answer: £15.20

a population of muskrats oscillates 33 above and below average during the year, hitting the lowest value in january. the average
Andru [333]

Answer:

P = 867(1.07)^t

Step-by-step explanation:

The population of muskrats oscillates 33 above and below average during the year, hitting the lowest value in january.

If the average value = 900 muskrats

Then the lowest = 900 - 33 = 867

It increases by 7 % each month

R = 7%

equation for the population p in terms of the months since january t will be

P = Po( 1 + R%)^t

P = 867( 1 + 0.07) ^t

P = 867(1.07)^t

The measure of central angle YCZ is 80 degrees. Circle C is shown. Line segments X C, W C, Y C, and Z C are radii. The length of
Nana76 [90]

Answer:

The sum of the areas of the two shaded sectors is 36\pi\ units^{2}

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The area of a circle is equal to

A=\pi r^{2}

where

r is the radius of the circle

in this problem we have

r=9\ units

substitute

A=\pi (9)^{2}=81 \pi\ units^{2}

Remember that

360\° subtends the complete circle of area equal to 81 \pi\ units^{2}

so

By proportion

Find the area of the two shaded sectors

\frac{81\pi }{360}=\frac{x}{2*80}\\ \\x=160*81\pi/360\\ \\x=36\pi\ units^{2}

madreJ [45]

Answer:

8/12

Step-by-step explanation:

Given that:

Dividing into 12 steps

Total step, fraction = 1

Each of the 12 steps = 1/12

If two steps is completed in one day:

. Steps completed per day :

2 (1/12)

= 2 /12 steps per day

Fraction of steps completed after 4 days

Fraction of steps per day * number of days

2 /12 * 4

(4*2) / 12

8/12
