Answer:

Step-by-step explanation:

To find a certain percentage of a number, we need to get the decimal equivalent of the percentage and then multiply this with the number.

For our problem given, we need to multiply 72 with the decimal equivalent of 310%.

How do we convert percentage to decimal?

We divide by 100. So we have:

310% = 310/100 = 3.1

Now, we multiply:

3.1 * 72

∠A and \angle B∠B are supplementary angles. If m\angle A=(4x-30)^{\circ}∠A=(4x−30)

user100 [1]

Answer:

the measure of ∠A. is 87∘

Step-by-step explanation:

Two angles are said to be supplementary angles if the sum of those angles is 180 degrees.

_________________________________________________

Given

∠A=(4x−30) ∘

∠B=(4x−14) ∘

Fir angles to be supplementary

∠A + ∠B = 180

(4x−30) ∘ + (4x−14) ∘ = 180∘

(8x -54 )∘ = 180∘

=> 8x = 180∘ + 54∘= 234∘

=> x = 234∘/8 = 29.25∘

Thus,

∠A=(4x−30) ∘

∠A=(4*29.25−30) ∘ =( 117 - 30 ) ∘ = 87∘

Thus,

the measure of ∠A. is 87∘

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.
