Consider that 1 inch = 2.54 centimeters. Which three statements are true for converting 18 feet to centimeters?

Answers

Answer:

There are 548.64 cm in 18 feet.

Step-by-step explanation:

We know that, 1 inch = 2.54 centimeters.

We need to convert 18 feet to centimeters

Also, 1 foot = 12 inch

Firstly we will convert 18 feet to inch.

18 feet = 12 × 18 inch

= 216 inch

Now to convert 18 feet to centimeters, multiply 216 inch by 2.54 cm as follows :

216 inch = 2.54×216 centimeters

= 548.64 cm

Hence, there are 548.64 cm in 18 feet.

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (8, - 3) and (x₂, y₂ ) = (2, 6)

x=36/2=18

∠1 =3x-9

What is the approximate value of x in this figure?
19 POINTS

Answers

Answer:

4.69 inches (2 decimal places)

Step-by-step explanation:

Refer to image attached to this answer:

Using Pythagoras Theorem:

[tex]AB^2+AC^2=BC^2[/tex]

[tex]2^2+3^2=BC^2[/tex]

[tex]4+9=BC^2[/tex]

[tex]BC^2=13[/tex]

-------------------------

Using Pythagoras Theorem,

[tex]BC^2+CD^2=BD^2\ (x)[/tex]

[tex]13+3^2=BD^2[/tex]

[tex]13+9=BD^2[/tex]

[tex]BD=\sqrt{22} = 4.69\ (2d.p.)[/tex]

First, we have to find the last remaining side of the leftmost triangle.

We can use the Pythagorean theorem.

The Pythagorean theorem: a^2 + b^2 = c^2

a = one leg

b = the second leg

c = the hypotenuse

In this problem,

a = 3

b = 2

c = ?

Let's plug our numbers into the Pythagorean theorem.

3^2 + 2^2 = c^2

Simplify the left side

9 + 4 = c^2

Add together like terms

13 = c^2

Take the square root of both sides

[tex]\sqrt{13}[/tex] = c

Now we can use the Pythagorean theorem on the rightmost triangle to find x.

a = 3

b = [tex]\sqrt{13}[/tex]

c = x

let's plug our values into the Pythagorean theorem.

3^2 + ([tex]\sqrt{13}[/tex])^2 = (x)^2

Simplify the left side

9 + 13 = x^2

Add together like terms

22 = x^2

Take the square root of both sides

[tex]\sqrt{22}[/tex] = x

But the problem is asking for the approximate value, the approximate value of [tex]\sqrt{22}[/tex] = 4.69 in

Multiply the numbers until you get the same denominator (Bottom number) for both fractions. I will do #1 to show you.

1/3    1/2

Both 3 and 2 go into 6, so I will use that.

When multiplying the bottom , you have to do the same to the top, so...

2/6  OR  3/6

3/6 is greater, so that is the answer.

Therefore, 1/2 is more

The 7th term of an AP is 4 and its common difference is -4. What is the first term?

Answers

Answer: 28

Step-by-step explanation:

The 7th term of an AP is 4 and its common difference is -4. The 7th term of an arithmetic progression is written as:

a + 6d = 4

where,

a = first term

d = common difference= -4

a + 6d = 4

a + 6(-4) = 4

a - 24 = 4

a = 4 + 24

a = 28

The first term is 28.

Diane and Fran live in Warren, which is 108.7 miles away from the mall. If the average mileage of the car is 25.6 mpg, what is the consumption of gas for the round-trip?

Answers

Answer:

Consumption of gas = 8.5 gallon (Approx)

Step-by-step explanation:

Given:

Distance from mall = 108.7 miles

Average of car = 25.6 mpg

Find:

Consumption of gas

Computation:

Total distance covers = 2(108.7)

Total distance covers = 217.4 miles

Consumption of gas = 217.4 / 25.6

Consumption of gas = 8.4921

Consumption of gas = 8.5 gallon (Approx)
