Answer:80

Step-by-step explanation:

60/100*x=48

60/100=3/5 so,

3/5*x=48

3x=48*5

x=240/3

x=80

therefore the maximum capacity is 80 people

If 5-3(2a+1)=-4+10, what is the value of a+2

givi [52]

$\\ \rm\Rrightarrow 5-3(2a+1)=-4+10$

$\\ \rm\Rrightarrow 5-6a-3=6$

$\\ \rm\Rrightarrow -6a+2=6$

$\\ \rm\Rrightarrow -6a=6-2$

$\\ \rm\Rrightarrow -6a=4$

$\\ \rm\Rrightarrow a=\dfrac{4}{-6}$

$\\ \rm\Rrightarrow a=\dfrac{2}{-3}$

Now

$\\ \rm\Rrightarrow a+2$

$\\ \rm\Rrightarrow \dfrac{2}{-3}+2$

$\\ \rm\Rrightarrow \dfrac{2-6}{-3}$

$\\ \rm\Rrightarrow \dfrac{-4}{-3}$

$\\ \rm\Rrightarrow \dfrac{4}{3}$

The missing figure is attached down

The length around the outside of the track is about 431 feet

Step-by-step explanation:

A running track has the shape of a rectangle capped with a semicircle on each end

The track is 80 feet wide
The rectangular portion of the track is 90 feet tall

We need to estimate the length around the outside of the track

The length of the outside the track is the length of two semi-circle and two straight lengths of the rectangle

∵ The track is 80 feet wide

- From the figure the width of the track is the diameter of the

semi-circles

∴ The diameter of each semi-circle = 80 feet

∵ The radius of a circle is half its diameter

∴ The radius of each semi-circle = $\frac{1}{2}$ × 80 = 40 feet

∵ The length of a circle = 2πr

∴ The length of a semi-circle = πr

∴ The length of two semi-circle = 2 × πr

- Substitute r by 40

∴ The length of two semi-circle = 2 × π(40) = 80π feet

∵ The rectangular portion of the track is 90 feet tall

∴ The length of the rectangle = 90 feet

∴ The two straight parts of the track = 2 × 90 = 180 feet

- Add the length of the two semi-circles and the two straight

parts to find the length of the track

∵ Length of the track = 80π + 180

- Substitute π by 3.141

∴ Length of the track = 80(3.141) + 180

∴ Length of the track = 431.28 ≅ 431 feet

The length around the outside of the track is about 431 feet

he sum of the first two terms of a G.P is 27 whereas the sum of the second and third term is 54. Find the first term and the com

viktelen [127]

Answer:

${ \tt{sum = \frac{a(r {}^{n - 1} )}{n - 1} }} \\ 27 = \frac{a(r {}^{2 - 1} )}{2 - 1} \\ { \bf{27 = ar - - - (i)}} \\ \\ 54 = \frac{a( {r}^{3 - 1} )}{3 - 1} \\ { \bf{108 = a {r}^{2} - - - (ii) }} \\ { \tt{(ii) \div (i) : }} \\ r = \frac{108}{27} \\ { \bf{common \: ratio = 4}} \\ { \bf{first \: term = \frac{27}{4} }}$

Help plsss<br> It’s due in soooon

djyliett [7]

Answer:

7/12.

Step-by-step explanation:

There are 12 numbers totals.

The numbers 1, 7, 11, 8, 2, 4, and 10 are not in Set Q.

There are seven of those numbers which means that the probability of a number not being in Set Q is 7/12.
