MARKING YOU BRAINLIST AND 5 STARS! A tire from Karen's car is shown below. Which is the closest to the distance traveled, in feet, after 3 full rotations of the tire? The diameter is 2 feet, by the way.
Answer:
18.86 feet
Step-by-step explanation:
One rotation of the tire is equal to the circumference of the tire
The formula for circumference of a circle (remember that a tire is shaped as a circle) = πd
where
π = 22/7
d = diameter
The size of one revolution = 2 x 22/7 = 44/7 feet
The distance covered in one rotation of the tire is 44/7 feet
The distance covered in 3 rotations = (44/7) x 3 = 18.86 feet

laura has 160 pounds of green beans at her vegetable stand. she sells 10 pounds of green beans every hour, what is the percent decrease in green beans after 3 hours?
Answer:
18.75%
Step-by-step explanation:
Green beans = 160 pounds
Amount sold in 1 hour = 10 pounds
Amount sold in 3 hours = 3x10= 30 pounds
Decrease in 3 hours = 30 pounds
% decrease = (30/160) x 100
=300/16
=75/4
=18.75%

What is the measure of XZW
Answer:
∠XZW = 95°
Step-by-step explanation:
∠YXZ = 180 - 150
∠YXZ = 30°
∠XZY = 180 - (30+65)
∠XZY = 180 - 95
∠XZY = 85°
∠XZW = 180 - 85
∠XZW = 95°

Given function:
y= -2(x-3)² +4Vertex form:
y = a(x − h)² + kAxis of symmetry is the line parallel to y-axis and passes through vertex. The x-coordinate of the vertex is determined by the value of h in the above equation.
We have h = 3 as per given equation for the function.
Axis of symmetry is the line x = 3

Answer:
c. 11
Step-by-step explanation:
By the property of intersecting secants outside of a circle, we have:
[tex] m\angle R = \frac{1}{2} \times (175\degree - 75\degree) [/tex]
[tex] m\angle R = \frac{1}{2} \times 100\degree [/tex]

Priya's family exchanged 250 dollars for 4250 pesos. Priya bought a sweater that was for 25 dollars. How many pesos did she spend?
Answer:
P425
Step-by-step explanation:
Given data
We are given that the family exchanged
$250 for P4250
the rate is
$250 for P4250
$1 will be x
x= 4250/250
x= P17
the pesos equivalent of $25 will be
= 25*17
= P425

What is the product of (3x + 1)(3x – 4)?
Step by step.
Answer:
9x^2-9x-3
Step-by-step explanation:
3x*3x=9x^2
3x*-4=-12x
1*3x=3x
1*-4=-3
9x^2-12x+3x-3
9x^2-9x-3
Answer:
9x^2 - 9x - 4
Step-by-step explanation:
(3x + 1)(3x – 4)
Here you can use the FOIL method (FOIL stands for: First, Outer, Inner and Last)
First you multiply 3x by 3x since these are the First inside both binomials.
3x * 3x = 9x^2
Then you multiply 3x by -4 since these are the Outer inside both binomials.
3x * -4 = -12x
Then you multiply 1 by 3x since these are the Inner inside both binomials.
1 * 3x = 3x
Then you multiply 1 by -4 since these are the Outer inside both binomials.
1 * -4 = -4
And finally add everything together:
9x^2 + (-12x) + 3x + (-4)
Since adding a negative number is the same as subtracting it:
9x^2 - 12x + 3x - 4
We can now simplify this a little by adding all the x's together:
9x^2 - (12x + 3x) - 4 =
9x^2 - 9x - 4
Hope I could help you understand!

Kenny is putting a brick border around his irregular shaped garden. Before installing the border, Kenny must
cut the bricks to fit the angles of the garden. Use the given measures to answer the question.
mzA=x
mZB=(5x-5)
m2C =(2x +20)
mZD=(3x-15)
mZE =(4x)
What are the angle measures of each vertex of the garden? Show your work.
Answer:
m<a=36
m<b=175
m<c=92
m<d=93
m<e=144
Step-by-step explanation:
since the shape has 5 sides we can determine the sum of the measure of interior angels with the equation 180×(n-2). replacing n with 5 would bring us to 180×3 equalling 540. since all the angels must add up to 540 we can combine them together to get it to 15x=540. simplify to get x=36. sub in x in the equations.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
Eber ran 3 miles. He stopped to take a break every 3/4 mile.
Then the number of times that Eber stop, including his final stop at the end of his run, will be given as,
⇒ 3 ÷ (3/4)
⇒ 3 x (4 / 3)
⇒ 4 times
