A triangle is such that the largest angle is three times the smallest angle. Find the measure of each angle
sammy [17]
Let x represent the smallest angle. Then the largest is 3x, and the remaining angle is 180-4x. The problem statement tells us
.. 3x > 180 -4x > x
Adding 4x gives us
.. 7x > 180 > 5x
or
.. 36 > x > 180/7 = 25 5/7

The angles, smallest to largest, are
.. x, 4(45 -x), 3x
where 25 5/7 < x < 36

The angles could be, for example, any of ...
.. 26°, 76°, 78°
.. 30°, 60°, 90°
.. 32°, 52°, 96°
.. 35°, 40°, 105°
and an infinite number of other possibilities.

Jessica's Furniture Store manager is trying to figure out how much to charge for an armchair that just arrived. The chair was pu
VARVARA [1.3K]

Answer: The manager should sell the chair for $1740.

Step-by-step explanation:

45% of 1200       Solve this to find the amount increase

0.45 * 1200 =  540      Now add this amount to find the price.

$1200 + $540 = $1740

or  you could do it this way

100% + 45% =  145%

145% of 1200 =?

1.45 * 1200 = 1740

Drag the tiles to the boxes to form correct pairs. Find the probability for the given situations, and then match the situations
frozen [14]

Answer:

  • 3 (die)
  • 4 (slips)
  • 6 (spinner)
  • 5 (ace)

Step-by-step explanation:

Josie rolls a six-sided die 18 times. What is the estimated number of times she rolls a two? 3 = (1/6)(18)

Slips of paper are numbered 1 through 10. If one slip is drawn and replaced 40 times, how many times should the slip with number 10 appear? 4 = (1/10)(40)

A spinner consists of 10 equal- sized spaces: 2 red, 3 black, and 5 white. If the spinner is spun 30 times, how many times should it land on a red space? 6 = (2/10)(30)

A card is picked from a standard deck of playing cards 65 times and replaced each time. About how many times would the card drawn be an ace? 5 = (4/52)(65)

_____

The probability of a given event is the number of ways it can occur divided by the number of possibilities. For example, a 2 is one of 6 numbers on a die, so we expect its probability of showing up to be 1/6. The expected number of times it will show up in 18 rolls of the die is (1/6)(18) = 3.
