Mathematics

Answer:

x = 84°

Step-by-step explanation:

The sum of the interior angles of a pentagon is equal to 540°.

x + 107 + 108 + 110 + 131 = 540

x + 456 = 540

x + 456 - 456 = 540 - 456

x = 84

Answer:

x = 84

Step-by-step explanation:

If you add up all of the internal angles in ANY pentagon it will be 540, so

x = 540 - (131+108+107+110)

A Fruit Stand sells 6 oranges for $3.00 and grapefruit for $2.40 people buy 10 oranges and 11 grapefruits much does the fruit sp
Harlamova29_29 [7]
<span>The <u>correct answer</u> is:

$31.40.

Explanation<span>:

Since 6 oranges cost $3.00, we can divide to find the cost of one orange:

3.00/6 = $0.50. Each orange costs $0.50.

If ten oranges are bought, this would cost 10(0.50)=$5.00.

Each grapefruit costs $2.40; 11 of them would cost 11(2.40) = 26.40.

Together the total cost is $5+$26.40 = $31.40.</span></span>

There is a population of 15,500 bacteria in a colony. If the number of bacteria doubles every 234 hours, what will
saveliy_v [14]

Answer:

2,48,000

Step-by-step explanation:

  • Initial population of bacteria = 15,500

  • Bacteria doubles after every 234 hours

  • So, after 0 (zero) hours, no of bacteria = 15,500

  • After 234 hours, no. of bacteria = 2(15,500) = 31,000

  • After 468 hours, no. of bacteria = 2(31,000) = 62,000 (2*234 = 468)

  • After 702 hours, no. of bacteria = 2(62,000) = 124,000 (3*234 = 702)

  • After 936 hours, no. of bacteria = 2(124000) = 2,48,000 (4*234 = 936)

A circle has a radius of 3. An arc in this circle has a central angle of 20°
Alla [95]

Answer:

The length of the arc is 1.0467

Step-by-step explanation:

First of all to solve this problem we need to use the circumferenc formula of a circle:

c = circumference

r = radius = 3

π = 3.14

c = 2π * r

we replace with the known values

c = 2 * 3.14 * 3

c = 18.84

The length of the circumference is 18.84

Now we have to divide the 20° by the 360​​° that a circle has, to know what part of the circle it represents

20° / 360° = 1/18

Now we multiply this fraction by the circumference and obtain the length of the arc

1/18 * 18.84 = 1.0467

The length of the arc is 1.0467
