In ΔXYZ, x = 5.9 meters, y = 8.9 meters, and z = 5.8 meters. Find the remaining measurements of the triangle, and round your answers to the nearest tenth.

Answers

Answer 1

Answer:

Angles: 40.9°, 99.05°, 40.05°

Step-by-step explanation:

Triangles

When we are given the lengths of the 3 sides of a triangle, we can easily compute all the internal angles by using the cosine's law or formula. Being x,y and z the sides of a triangle, and \alpha, \beta , \gamma the three opposite angles respectively, then

[tex]x^2=y^2+z^2-2yzcos\alpha[/tex]

[tex]y^2=x^2+z^2-2xzcos\beta[/tex]

[tex]z^2=x^2+y^2-2xycos\gamma[/tex]

We have x=5.9, y=8.9, z=5.8, then from

[tex]x^2=y^2+z^2-2yzcos\alpha[/tex]

We solve for [tex]\alpha[/tex]

[tex]\displaystyle cos\alpha=\frac{y^2+z^2-x^2}{2yz}[/tex]

[tex]\displaystyle cos\alpha=\frac{8.9^2+5.8^2-5.9^2}{2\times 8.9\times 5.8}[/tex]

[tex]cos \alpha=0.756[/tex]

[tex]\alpha=40.9 ^o[/tex]

Similarly

[tex]\displaystyle cos\beta=\frac{x^2+z^2-y^2}{2xz}[/tex]

[tex]\displaystyle cos\beta=\frac{5.9^2+5.8^2-8.9^2}{2\times 5.9\times 5.8}[/tex]

[tex]cos\beta=-0.157[/tex]

[tex]\beta=99.05^o[/tex]

Finally

[tex]\displaystyle cos\gamma=\frac{5.9^2+8.9^2-5.8^2}{2\times 5.9\times 8.9}[/tex]

[tex]cos\gamma=0.765[/tex]

[tex]\gamma=40.05^o[/tex]

12) The school that Danielle goes to is selling tickets to a choral performance. On the first day of
ticket sales the school sold 5 senior citizen tickets and 9 student tickets for a total of $144. The
school took in $192 on the second day by selling 14 senior citizen tickets and 6 student tickets.
What is the price each of one senior citizen ticket and one student ticket?

Answers

Answer:

Senior citizen tickets = $9

Student tickets = $11

Step-by-step explanation:

We begin by converting these into simultaneous linear equation;

Senior citizen tickets = a

Student tickets = b

5a + 9b = 144

14a + 6b = 192

5a = 144 - 9b

a = 144/5 - 9b/5

a = 28.8 - 1.8b

We now substitute this into the first equation

14(28.8 - 1.8b) + 6b = 192

403.2 - 25.2b +6b = 192

-19.2b = 192 - 403.2

b = -211.2/-19.2

b = 11

Put the value of b into either equation

5a + 9b = 144

5a + 9(11) = 144

5a +99 = 144

5a = 144-99

5a = 45

a = 9

A scale diagram of a garden shows the length as 14.5 cm. If the scale is 1:150, what is the actual length? The garden is m in length

Answers

Final answer:

The actual length of the garden is 2175 cm.

Explanation:

To find the actual length of the garden, we can use the scale. The scale indicates that 1 cm on the diagram represents 150 cm in real life. Since the length on the diagram is 14.5 cm, we can multiply this length by the scale factor to find the actual length.

Actual Length = Length on Diagram × Scale Factor = 14.5 cm × 150 = 2175 cm

Therefore, the actual length of the garden is 2175 cm.

John paid $34 for 2 books and 3 pencils. He paid $36 for 3 books and 2 pencils. How much was each?

Answers

Cost of each book is $ 8 and cost of each pencil is $ 6

Solution:

Let "a" be the cost of 1 book

Let "b" be the cost of 1 pencil

John paid $34 for 2 books and 3 pencils

Therefore,

2 books x cost of 1 book + 3 pencil x cost of 1 pencil = 34

[tex]2 \times a + 3 \times b = 34[/tex]

2a + 3b = 34 ----------- eqn 1

He paid $36 for 3 books and 2 pencils

3 books x cost of 1 book + 2 pencil x cost of 1 pencil = 36

[tex]3 \times a + 2 \times b = 36[/tex]

3a + 2b = 36 -------- eqn 2

Let us solve eqn 1 and eqn 2

Multiply eqn 1 by 2

4a + 6b = 68 ---------- eqn 3

Multiply eqn 2 by 3

9a + 6b = 108 --------- eqn 4

Subtract eqn 3 from eqn 4

9a + 6b = 108

4a + 6b = 68

( - ) -------------

5a = 40

a = 8

Substitute a = 8 in eqn 1

2(8) + 3b = 34

16 + 3b = 34

3b = 34 - 16

3b = 18

b = 6

Thus cost of each book is $ 8 and cost of each pencil is $ 6

Step-by-step explanation:

The given is:

Western North Carolina Woods have a deer population density of 3.5 deer per acreThere are a total of 435 deer

We need to find how many acres are in this parcel of woods

∵ The population density = 3.5 deer per acre

- That means 1 acre for every 3 dears

∵ There are a total of 435 deer

∴ [tex]\frac{3.5}{1}=\frac{435}{x}[/tex] , where x is the number of acres

- By using cross multiplication

∴ 3.5 × x = 1 × 435

∴ 3.5 x = 435

- Divide both sides by 3.5

∴ x = 124.29

There are about 124.29 acres in this parcel woods

What number is halfway between .2 and .3

Answers

Final answer:

The number halfway between 0.2 and 0.3 is 0.25, which is found by adding the two numbers and dividing the total by 2.

Explanation:

The number halfway between 0.2 and 0.3 can be found by calculating the average of the two numbers. To find the average, you add the two numbers together and then divide by 2.

To show the steps:

Add 0.2 and 0.3 together: 0.2 + 0.3 = 0.5.Divide the sum by 2 to get the midpoint: 0.5 ÷ 2 = 0.25.

Therefore, the number that is halfway between 0.2 and 0.3 is 0.25.

The number halfway between 0.2 and 0.3 is 0.25.

To find the number halfway between 0.2 and 0.3, you calculate the average of the two numbers. Here's the step-by-step process:

Add the two numbers together: 0.2 + 0.3 = 0.5.Divide the sum by 2 to get the average: 0.5 / 2 = 0.25.

So, the number halfway between 0.2 and 0.3 is 0.25. This method ensures that you find the exact midpoint between two values.

The round wading pool at the Greenville Community Center has a diameter of 8 feet. What is the pool's circumference? use 3.14 for pi

Answers

Answer:

25.12 feet

Step-by-step explanation:

To find the circumference of the round wading pool with an 8-foot diameter using 3.14 for pi, the formula C = πd is used, resulting in a circumference of 25.12 feet.

The question is asking to find the circumference of a round wading pool with a diameter of 8 feet using 3.14 for pi. The formula for the circumference of a circle is C = πd, where C represents the circumference, π (pi) is approximately 3.14, and d is the diameter of the circle. Given that the diameter (d) of the pool is 8 feet, we substitute the values into the formula to get:

C = 3.14 × 8 feet = 25.12 feet

Therefore, the circumference of the wading pool is 25.12 feet.

A line has a slope of -1/7 and passes through (4, -2) and (p, -1) what is the value of p

Answers

Answer:

Therefore the value of p is -3.

Step-by-step explanation:

Given a line has a slope of [tex]-\frac{1}{7}[/tex] and passes through (4,-2)and (p,-1)

The slope of a line which passes through [tex](x_1,y_1)[/tex]   and   [tex](x_2,y_2)[/tex] is

[tex]=\frac{y_2-y_1}{x_2-x_1}[/tex]

Here [tex]x_1= 4,y_1=-2, x_2=p[/tex] and [tex]y_2= -1[/tex]

Therefore the slope of the line which passes through the given points is

[tex]=\frac{-1+2}{p-4}[/tex]

According to the problem,

 [tex]\frac{-1+2}{p-4}= -\frac{1}{7}[/tex]

[tex]\Leftrightarrow \frac{1}{p-4} =-\frac{1}{7}[/tex]

[tex]\Leftrightarrow p-4=-7[/tex]

[tex]\Leftrightarrow p = -7+4[/tex]

[tex]\Leftrightarrow p = -3[/tex]

Therefore the value of p is -3.
