Mathematics

Andre45 [30]2 years ago
8 0

Step-by-step explanation:

a. Obtuse Scalene Triangle. It has one angle that is greater than 90 degrees and have two equal sides so it's a obtuse scalene triangle.

b. A triangle interior add up to 180 degrees. We are given the upper angle which is 173. The other two angles must add to 180 but must be equal.

x + y + z = 180

y = z

x + z + z = 180

x + 2z = 180

x=173 so

173 + 2z = 180

2z = 7

z = 3.5

3.5 degrees.

A sphere-shaped water balloon can extend to a diameter of 3.5 inches before it explodes.
ollegr [7]
Volume of a spehere=(4/3)πr³

Data:
diameter=3.5 in
π=3.14

1)we calculate the radius:
r=diameter/2=3.5 in / 2=1.75 in

2) we calculate the volume of this sphere:
volume=(4/3)*3.14*(1.75 in)³=22.4379...in³≈22.44 in³.

Answer: 22.44 in³

in a game involving a pair of fair dice a player rolls the dice until he gets a sum of 7 let z equal the number of rolls it take
Anarel [89]

Answer:

z = 36 rolls , probability for getting 7 = 1/6

Step-by-step explanation:

A die has 6 possible outcomes, which sums to 36 for two dice for every value on both dice.

The outcomes for rolling both dice for 36 times gives 6 possible outcomes summing to 7, that is, (1, 6), (2, 5), (3, 4), (4, 3), (5, 2), and (6, 1).

There the probability of getting a sum dice of 7 is:

= 6 / 36 = 1/6

Which of the following fractions is equivalent to -84/-90 in the least common terms?
abruzzese [7]
Answer: 14/15

This is because to get to 14/15 you must divide by 6 but when getting to 42/45 you must divide 2. Therefore 14/15 is your answer because the problem went to the most reduced fraction.
