A piece of art is in the shape of an equilateral triangle with sides of 13 in. Find the area
of the piece of art. Round your answer to the nearest tenth.

Answers

Answer 1

Answer:

73.2sq.in

Step-by-step explanation:

Area of the triangle = 1/2 * base * height

Get the height using the pythagras theorem

h^2 = 13^2 - (13/2)^2

h^2 = 169 - (6.5)^2

h^2 = 169 - 42.25

h = 11.26in

Area of the triangle = 1/2 * 13 * 11.26

Area of the triangle = 6.5 * 11.26

Area of the triangle = 73.2sq.in

Hence the area of the triangle to nearest tenth is  73.2sq.in

An experiment consists of rolling a number cube (dice). What is the probability of rolling a number GREATER THAN 4? Express your answer as a fraction in the simplest form.

Answers

Answer:

1/3

Step-by-step explanation:

Probability is the likelihood or chance that an event will occur

Probability = Expected/Total outcome

Since the experiment requires rolling a dice

S = {1, 2, 3, 4, 5, 6}

Total outcome n(S) = 6

Number greater than 4 are;

Events E = {5,6}

Expected outcome n(E) = 2

Probability of rolling a number greater then 4 = 2/6

Probability of rolling a number greater then 4 = 1/3

[tex]x \in [1, 6)[/tex]

Step-by-step explanation:

Because the function is decreasing:

[tex]g(x_1) > g(x_2) \iff x_1 < x_2[/tex]

So:

[tex]g(x^2) > g(5x + 6) \iff x^2 < 5x + 6\\x^2 < 5x + 6\\x^2 - 5x - 6 < 0\\x^2 - 5x + 6.25 - 12.25 < 0\\x^2 - 2\cdot 2.5x + 2.5^2 < 12.25\\(x - 2.5)^2 < 12.25\\x - 2.5 \in (-3.5; 3.5)\\x \in (-1; 6)\\[/tex]

Combining that with the domain [tex]D_g = [1; \infty )[/tex]

Ronald has 5 2/3 cups of a smoothie he then drank 1 3/4 cups of the smoothie how many cups were left

Answers

Answer:

4 1/6 cups of the smoothie were left.

Step-by-step explanation:

The LCD here is (3)(4) = 12.

Thus, 5 2/3 cups equals 5 8/12 and 1 3/4 cups equals 1 6/12 cups.

Subtract 1 6/12 cups from the original 5 8/12 cups.  We get:

5 8/12

-1  6/12

-----------

 4 2/12, or 4 1/6.

Answers

Answer:

red = 28 apples

green = 13 apples

equations:

r + g = 41

r = g + 15

Step-by-step explanation:

r = number of red

g = number of green

r = g + 15 (the number of red apples is 15 more than the number of green apples)

r + g = 41

Substitute the firs equation into the second and solve for a numerical value of g

(g + 15) + g = 41

2g + 15 = 41

2g = 26

g = 13

Now solve for a numerical value of r

r = g + 15

r = 13 + 15

r = 28

checking the math:

r + g = 41

28 + 13 = 41

4. Allison drew a triangle with 2 congruent sides and 1 obtuse angle. Which terms accurately describe the triangle? Select all that apply. A. Acute B. Isosceles C. Obtuse D. Scalene​

Answers

Answer: I have been asked the same question I believe that it is obtuse and isosceles.

Step-by-step explanation: Well a triangle with 1 obtuse angle means it is an obtuse triangle but a triangle with 2 congruent means it is an isosceles triangle.

This angle is isosceles as well as obtuse.

What is an isosceles triangle?

Isosceles triangle is a triangle that has two equal sides.

What is an obtuse-angled triangle?

An obtuse-angled triangle is a triangle that consists of an interior angle of more than a right-angle (90)°.

As this triangle has two congruent side, it is an isosceles triangle.

Similarly, it has one obtuse angle. Therefore, this triangle is an obtuse-angled triangle.

Hence, for this triangle, B. Isosceles C. Obtuse both apply.

Elena spent $16, including tax, on 4 centimeters of wooden board. what is the cost, in dollars, per centimeter of board

Answers

Answer:

$4 per centimeter

Step-by-step explanation:

16/4=$4

Elena spent $4 per centimeter on board if she spent $16, including tax, on 4 centimeters of wooden board.

What is a fraction?

Fraction number consists of two parts one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

We have:

Elena spent $16, including tax, on 4 centimeters of wooden board.

Let's suppose the cost per centimeter of the board is x.

Mathematically,

Elena spent $16 on 4 centimeters

Elena spent $x on per centimeters

[tex]\frac{16}{x}= \frac{4}{1}[/tex]

4x = 16  (after cross multiplicayion)

x = $4   (divide by 4 on both sides)

Thus, Elena spent $4 per centimeter on board if she spent $16, including tax, on 4 centimeters of wooden board.
