A blueprint for a new house has a scale of 1:50. Here are the dimensions of two rooms. Calculate the dimensions of each room on

Lorico [155]

Answer:

a.) =30.72*50

b.)13.02*50

Step-by-step explanation:

you got to calculate the area of the two rooms by multipling the sides.

as we know that the scale is 1:50, this means for every 1meter it is 50 meters.

once we have calculated the area of the space used multply it by 50 to get the area dimensions occupied

Find the perimeter of this semi-circle with diameter, d = 18cm. Give your answer as an expression in terms of pi.

OLga [1]

Answer:

The perimeter of the given semi-circle in terms of $\pi$ is

$P=9\pi$ cm

Step-by-step explanation:

Given that the diameter of the semi-circle is 18cm

That is d=18cm

Therefore radius $r=\frac{d}{2}$

$r=\frac{18}{2}$

Therefore radius r=9cm

To find the perimeter of the semi-circle :

perimeter of the semi-circle $P=\pi r$

$P=\pi\times 9$ cm (where r=9 cm )

$P=9\pi$ cm

The perimeter of the given semi-circle in terms of $\pi$ is

$P=9\pi$ cm

Find xif 4; 4+2×;4+4× are in Geometric sequences

Ray Of Light [21]

Given:

$4,4+2x,4+4x$ are in geometric sequences.

To find:

The value of x.

Solution:

If a, b, c are in geometric sequences, then

$\dfrac{b}{a}=\dfrac{c}{b}$

$b^2=ac$ ...(i)

It is given that $4,4+2x,4+4x$ are in geometric sequences. By using (i), we get

$(4+2x)^2=(4)(4+4x)$

$4^2+2(4)(2x)+(2x)^2=(4)(4)+4(4x)$

$16+16x+4x^2=16+16x$

$4x^2=16+16x-16-16x$

On further simplification, we get

$4x^2=0$

$x^2=0$

$x=0$

Therefore, the value of x is 0.
