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

you move right 1 unit and left 3 units. you end at (-4,0). where did u start?
Answer:
(2,-4)
Step-by-step explanation:
you see (-4,0), then you do the opposite of what it says like it says right 1 unit. then you g left 1 unit. then it says left 3 units. so you go right 3, which results you starting at (2.-4)

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

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

= P425
The ratio of a model car to a regular car is 1:16. The model is 6.25 inches long. What is the length of the actual car in feet and inches? what if the ratio of the model car was 2:35, then what would be the actual length of the car?
Answer:
Step-by-step explanation:
model car 1 : regular car 16
model 6.25 inches : actual car 6.25*16 = 100 inches
1foot = 12 inches
100/12 = 8 feet and 4 inches
model car 2 : regular car 35
model 6.25 inches : actual car 6.25*35/2 = 109. 375 inches

Answer:
s = 17t = 5Step-by-step explanation:
The midpoint formula is useful here. For midpoint M, we have ...
M = (C + D)/2
2M = C + D
2(10, 10) = (15, s) +(t, 3)
(20, 20) = (15+t, s+3)
t = 20 -15 = 5
s = 20 -3 = 17
__
Check
(C +D)/2 = ((15, 17) +(5, 3))/2 = (20, 20)/2 = (10, 10) . . . checks OK

Plz help ASAP with circles
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]
[tex] (4x+6)\degree = 50\degree [/tex]
4x + 6 = 50
4x = 50 - 6
4x = 44
[tex] x = \frac{44}{4} [/tex]

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°

ez pts someebody help find the equation axis of symmetry of y=-2(x-3)^2 +4
Answer:
x = 3Step-by-step explanation:
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

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%

Eber ran 3 miles. He stopped to take a break every 34 mile. How many times did Eber stop, including his final stop at the end of his run? Use the model to help you answer this question.
The number of times that Eber stop, including his final stop at the end of his run, will be 4 times.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
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
The number of times that Eber stop, including his final stop at the end of his run, will be 4 times.
