Step-by-step explanation:
Consider that 1 inch = 2.54 centimeters. Which three statements are true for converting 18 feet to centimeters?
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.

Answer:
see explanation
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (8, - 3) and (x₂, y₂ ) = (2, 6)
m = [tex]\frac{6+3}{2-8}[/tex] = [tex]\frac{9}{-6}[/tex] = - [tex]\frac{3}{2}[/tex]
------------------------------------------
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
y = 5 - 2x , that is
y = - 2x + 5 ← in slope- intercept form
with slope m = - 2

help please? its geometry
Answer:
∠4=135
Step-by-step explanation:
vertical angles are always equal
∠1=∠3
3x-9=x+27
3x-x=27+9
2x=36
x=36/2=18
∠1 =3x-9
∠1=3(18)-9
∠1=54-9=45
∠1+∠4=180 degrees
45+∠4=180
∠4=180-45
∠4=135
What is the approximate value of x in this figure?
19 POINTS
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

Please help me, I’m struggling!
Answer:
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
Another way you can do this is to draw a pizza, a section off parts of it according to the fractions.
Hope this helped.

The 7th term of an AP is 4 and its common difference is -4. What is the first term?
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.
If US is an angle bisector of ZRUT, find mZRUT.
OmZRUT = 80°
OmZRUT = 40
OmZRUT = 20°
OmZRUT = 10°
If the measure of angle 1 is 110° and the measure of angle 3 is (2x+10)º, what is the value of x?
Answer:
x=50
Step-by-step explanation:
angle 1 and 3 are corresponding angles that menas they equal the same
so set it up like this 2x+10=110 solve for x
move over the 10, subtract 10 from 110 you get 100 and divide by 2
you get 50.

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?
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)

1. Mary is twice as old as her brother
Zane. Zane is four years less than
twice as old as his cousin Chase. If
Chase is 4 years old, how old is Mary?
Answer:
8
Step-by-step explanation:
mary = twice older than zane
zane=four yrs less than twice of chase
chase= 4
therefore;
twice of chase is 8 and zane is 4 years less so
8-4=4
and mary is twice older so
