3 baguettes and 2 rolls=£3

NISA [10]

Answer:

baguettes are b = $0.80

rolls are r = $0.30

Step-by-step explanation:

1b + 4r = 2

3b + 2r = 3 step 1 when we need to balance and make one the same

6b + 4r = 6 step 2 when both equations must have 1 same value ie) 4r we take 2r and x2 to all values on that same equation.

6b + 4r = 6

-

1b + 4r = 2 step 3 when both equations show add we subtract them

5b = 4

b = 4/5

b = 0.8 b = 0.8 = 4/5 step 4 when we find x we plug in for x in this case we found b and plug in for b

1(0.8) + 4r = 2

0.8 + 4r = 2

4r = 2 - 0.8

4r = 1.2

r = 1.2 /4

r = 0.3

Architect Brian Peters spent 60% of a week's time working on drawings for a new apartment building. If Brian spent 18 hours work

Kipish [7]

Answer:

Brian Peters worked for total of 45 hours.

Step-by-step explanation:

Let the total number of hours worked be 'x'.

Now Given:

Hours spent on other projects = 18 hours.

Also Given:

60% of a week's time working on drawings for a new apartment building.

Hours spent on new apartment building = $60\%\times x = \frac{60}{100}x=0.6x$

We need to find the total hours worked.

Solution:

Now we can say that;

total number of hours worked is equal to sum of Hours spent on new apartment building and Hours spent on other projects.

framing in equation form we get;

$x=0.6x+18$

Combining like terms we get;

$x-0.6x=18\\\\x(1-0.6)=18\\\\0.4x=18$

Now Dividing both side by 0.4 we get;

$\frac{0.4x}{0.4}=\frac{18}{0.4}\\\\x=45\ hrs$

Hence Brian Peters worked for total of 45 hours.

How long will it take for a falling object to reach 108 m/s if its initial velocity is 10 m/s?

defon

Answer:

t=10 s

Step-by-step explanation:

v=u+gt

108=10+9.8t

108-10=9.8t

9.8t=98

$t=\frac{98}{9.8} =\frac{980}{98} =10$

A cylinder with a radius of 6cm and height of 15 cm has a cylindrical cut out of the

suter [353]

Answer:

$V = 518cm^3$

Step-by-step explanation:

Given

$h = 15cm$

$R = 6cm$

$r =5cm$

Required

The volume of the remaining cylinder

Before the cut-out, the cylinder has a volume (V) of:

$V = \pi R^2h$

After the cut-out, the cylinder has a volume of:

$V = \pi [R^2 -r^2]h$

So, we have:

$V = 3.14* [6^2 -5^2]*15$

$V = 3.14* [36 -25]*15$

$V = 3.14* 11*15$

$V = 518cm^3$
