The members of a singing group agree to buy at least 250 tickets for a concert. The group buys 20 fewer lawn tickets than balcon

sveta [45]

Answer:

Members of Singing group will buy minimum 135 number of balcony tickets.

Step-by-step explanation:

Given:

Minimum of tickets will be bought =250

Let number of lawn tickets be 'l'.

Also Let number of balcony tickets be 'b'

Now given

The group buys 20 fewer lawn tickets than balcony tickets.

Framing in equation form we get;

$l=b-20$

Now The Sum of Number of balcony tickets and Number of lawn tickets should be greater than or equal to Minimum of tickets will be bought by the group.

Framing in equation form we get;

$l+b\geq 250$

Now substituting the value of 'l' in above equation we get;

$(b-20)+b\geq 250\\\\b-20+b\geq 250\\\\2b-20\geq 250\\\\2b\geq 250+20\\\\2b\geq 270\\\\b\geq \frac{270}{2}\\\\b\geq 135$

Now we know the value of b which is 135 we will substitute in equation $l=b-20$ to find the value of l we get;

$l=135-20 = 115$

Hence Members of singing group will buy minimum 135 number of balcony tickets.

a sector with the central angle measure of 4pi/5 (in radians) has a radius of 5 cm. What is the area of the sector? PLS HELP :(

katovenus [111]

Answer:

Area of the sector = 31.42 cm²

Step-by-step explanation:

Formula for the area of a sector is,

Area = $\frac{\theta}{2\pi }(\pi r^{2} )$

Here θ = central angle subtended by the arc (in radians)

r = radius of the circle

Now substitute the values given in the formula,

Area of the sector = $\frac{\frac{4\pi }{5}}{2\pi }\times \pi (5)^2$

= $\frac{4\pi }{10\pi } \times (25\pi)$

= $\frac{100}{10}\times \pi$

= 10π

= 31.416

≈ 31.42 cm²

Fofino [41]

Use the given slope and point to substitute into the point-slope formula
y - y1 = m (x - x1)

Slope-intercept form:
y = -5

Point-slope form:
y + 5 = 0 • (x + 7)
