A triangle has sides with lengths of 4 yards, 10 yards, and 11 yards. Is it a right triangle?
yes
no

Answers

Answer 1

Answer:

no

Step-by-step explanation:

for a triangle to be a right triangle, the sum of the square of its legs must equal the square of its hypotenuse

a² + b² = c²

in this problem, 4² + 10² ≠ 11²

16 + 100 ≠ 121

Find the size of the largest angle in the triangle,

Answers

Answer:

C=120 degrees

Step-by-step explanation:

We can use the law of cosines to find an angle when we have all three sides

(7)^2 = (5)^2 + (3)^2 -(2)(5)(3)Cos(C)

49 = 25 +9 -30Cos(c)

49= 34 -30Cos(c)

15 = -30Cos(c)

Cos(c) = -1/2

C=120 degrees

25 apples to 10 oranges. What is the rate of the fruit

Answers

Answer:

The rate of the fruit is 5 apples to 2 oranges.

Step-by-step explanation:

The rate of the fruit is the ratio of apples to oranges. That is, the number of apples divided by the number of oranges into its simplest fraction form:

[tex]x = \frac{25\,apples}{10\,oranges}[/tex]

[tex]x = \frac{5\,apples}{2\,oranges}[/tex]

The rate of the fruit is 5 apples to 2 oranges.

Mario plays basketball on a town league team. The
table below gives Mario's scoring statistics for last
season. How many points did Mario score playing
basketball last season?

Answers

Answer:

Step-by-step explanation:

Total points Mario scored = total 1-point free throw + total 2-point field goal + total 3-point field goal.

In 80 attempts 1-point free throw, Mario had 75% success rate. That is, Mario had 80 x 75/100 success

80 x 75/100 = 60

Thus, Mario scored 1 x 60 (since for each success, 1 points is added) points = 60

In 60 attempts 2-point field goal, Mario had 90% success rate. That is, Mario had 60 x 90/100 success

60 x 90/100 = 54

Thus, Mario scored 2 x 54 points (since for each success, 2 points are added) = 108

In 60 attempts 3-point field goal, Mario had 25% success rate. That is, Mario had 60 x 25/100 success

60 x 25/100 = 15

Thus, Mario scored 3 x 15 points (since for each success, 3 points are added) = 45

Therefore, the total points Mario scored = 60 + 108 + 45

= 213
