Answer:

The area of a triangle is: A = 23.2 cm²

Step-by-step explanation:

Given

a = 10 cm

b = 9 cm

The angle ∠C = 31°

To determine

Area of the triangle

Using the formula to determine the area of the triangle

Area = 1/2bc sin C

substituting a = 10, b = 9, and m∠C = 31°

Area = 1/2 × 9 × 10 × sin 31°

Area = 1/2(90) sin 31°

Area = 45 × sin 31°

Area = 23.2 cm²

Therefore, the area of a triangle is: A = 23.2 cm²

A piece of rope is 15.6 meters long. It is cut into 16 equal pieces. How long is each piece? Round your answer to the nearest tenth.

Answers

Answer:

1 m

Step-by-step explanation:

Given thta,

Length of a piece of rope = 15.6 m

It is cut into 16 equal pieces.

We need to find the length of each piece of rope.

Let the length of each piece is y m.

ATQ,

16 y = 15.6

⇒ y = 0.975

or

⇒ y = 1 m

Hence, the length of each piece is 1 m.

Find the length of the missing side (nearest tenth).
25 yd
37 yd

Answers

Answer:

27.3 yards

Step-by-step explanation:

Since this triangle is a right triangle, this can be solved using the equation:

a^2 + b^2 = c^2

c^2 is the side opposite to the right angle (37)

So, you need to change the equation to where it is set equal to b^2.

Subtract a^2 on both sides.

b^2 = c^2 - a^2

Now, plug in the numbers you have.

b^2 = 37^2 - 25^2

Simplify.

b^2 = 1369 - 625

b^2 = 744

Now, to find b, take the square root of 744.

√744 = 27.3

The width of a triangle is represented by 5 +2y. The length is twice as long as the width. What is the perimeter of the rectangle? Select all correct expressions.

Answers

Answer:

6(5+2y)

Step-by-step explanation:

We have width = w = 5+2y

L = length of the rectangle

Length has been give to be 2 x width

Width = w

So l = 2w

Perimeter of a rectangle = 2(l+w)

Since l = 2w, we have

2(2w+w)

= 2(3w)

= 6w

So since we already know w = 5+2y

We put this value into 6w

Then we will have this expression:

P = 6(5+2y)

Adam exchanged British pounds for Swiss franc He changed £400 into 592 francs What was the exchange rate of British pounds to Swiss franc

Answers

Answer: 1 : 1.48

Step-by-step explanation:

Adam was able to change £400 into 592 francs which means that the British pound is stronger because it was able to buy more Swiss francs.

The exchange rate can be gotten using direct proportion:

400 : 592

1       : x

Cross multiply:

400x = 592

x = 592/400

x = 1.48

Exchange rate is:

= 1 : 1.48

Answers

Answer:

(-9.5, -4)

Step-by-step explanation:

Given the ratio a:b (a to b) of two segments formed by a point of partition, and the endpoints of the original segment, we can calculate the point of partition using this formula:

[tex]( \frac{a }{a + b} (x_{2} - x_{1}) + x_{1}, \frac{a}{a + b} (y_{2} - y_{1})+y_{1})[/tex].

Given two endpoints of the original segment

→ (-10, -8) [(x₁, y₁)] and (-8, 8) [(x₂, y₂)]

Along with the ratio of the two partitioned segments

→ 1 to 3 = 1:3 [a:b]

Formed by the point that partitions the original segment to create the two partitioned ones

→ (x?, y?)

We can apply this formula and understand how it was derived to figure out where the point of partition is.

Here is the substitution:

x₁ = -10

y₁ = -8

x₂ = -8

y₂ = 8

a = 1

b = 3

[tex]( \frac{a }{a + b} (x_{2} - x_{1}) + x_{1}, \frac{a}{a + b} (y_{2} - y_{1})+y_{1})[/tex]. →

[tex]( \frac{(1) }{(1) + (3)} ((-8) - (-10)) + (-10), \frac{(1)}{(1) + (3)} ((8) - (-8))+ (-8))[/tex] →

[tex]( \frac{1}{4} ((-8) - (-10)) + (-10), \frac{1}{4}((8) - (-8)) + (-8))[/tex] →

[tex]( \frac{1}{4} (2) + (-10), \frac{1}{4}(16) + (-8))[/tex] →

[tex]( (\frac{1}{2}) + (-10), (4) + (-8))[/tex] →

[tex]( (-\frac{19}{2}), (-4))[/tex] →

[tex]( -\frac{19}{2}, -4)[/tex] →

Step-by-step explanation:

Given

1 + 2x + 1 = 10, that is

2 + 2x = 10 ( subtract 2 from both sides )

2x = 8 ( divide both sides by 2 )

x = 4

Then
