A car tire with a diameter of 1.6 ft rotates 275 degrees . How far does a point on the circumference of the tire travel
Answer:
A point on the circumference of the tire will travel 7.68 ft.
Step-by-step explanation:
Given;
radius of the car tire, r = 1.6 ft
angular distance or rotation = 275⁰
A complete rotation of the tire = 360⁰
the distance a point on the circumference will travel = 2πr
If 360⁰ = 2πr
then 275⁰ = ?
[tex]= \frac{275 \ \times \ 2\pi r}{360} = \frac{275 \ \times \ 2\pi \times 1.6ft}{360} = 7.68 \ ft[/tex]
Therefore, a point on the circumference of the tire will travel 7.68 ft.

Roció hará un circulo con un diámetro de 22.8 cm cuánto medirá un radio
Answer:
r = 11.4 cm
Step-by-step explanation:
The question says that, "Spray will make a circle with a diameter of 22.8 cm how long a radius will measure."
Given that,
The diameter of the circle, d = 22.8 cm
We know that the relation between the diameter and the circle is given by :
d = 2r
Where
r is the radius of the circle
r = d/2
r = 22.8/2
r = 11.4 cm
So, the radius of the circle is equal to 11.4 cm.
What is the measure of angle B
Answer:
Step-by-step explanation:
angle C + Angle B= Angle A(sum of two interior oppposite angles are equal to the exterior angle formed)
61+B=143
B=143-61
B=82 degree
We know that,
→ C = 61°
[A = B + C]
→ 143° = B + 61°
→ B = 143° - 61°
→ B = 82°
[180° = A + B + C]
→ 180° = A + (82° + 61°)
→ A = 180° - 143°
→ A = 37°

Find the area of the shape below
Answer:
Q1) 104m²
Q2) 121 in.²
Step-by-step explanation:
Q1)
GIVEN :-
Figure given in the question comprises of a triangle & a rectangle.Length of the rectangle = 10 mWidth of the rectangle = 8 m Base of the triangle = 8 mHeight of the triangle = 6 mTO FIND :-
Area of the figureGENERAL FORMULAES TO BE USED IN THIS QUESTION :-
For a triangle with height 'h' & base 'b' , its area = [tex]\frac{1}{2} \times b \times h[/tex].For a rectangle with length 'l' & width 'w' , its area = [tex]l \times w[/tex]SOLUTION :-
Area of the triangle = [tex]\frac{1}{2} \times 8 \times 6 = 24m^2[/tex]
Area of the rectangle = [tex]10 \times 8 = 80m^2[/tex]
Area of the figure = (Area of the triangle) + (Area of the rectangle)
= 24m²+ 80m²
= 104m²
Q2)
GIVEN :-
Figure given in the question comprises of a triangle & a trapezium.Lengths of parallel sides of trapezium are 6 in. & 7 in. Height of trapezium = 20 - 3 = 17 in.Base of the triangle = 3 in.Height of the triangle = 7 in.TO FIND :-
Area of the figureGENERAL FORMULAES TO BE USED IN THIS QUESTION :-
For a triangle with height 'h' & base 'b' , its area = [tex]\frac{1}{2} \times b \times h[/tex].For a trapezium with parallel sides whose lengths are 'a' & 'b' and height 'h' , its area = [tex]\frac{1}{2} \times (a +b) \times h[/tex]SOLUTION :-
Area of the triangle = [tex]\frac{1}{2} \times 3 \times 7 = \frac{21}{2} = 10.5 \; in.^2[/tex]
Area of the trapezium = [tex]\frac{1}{2} \times (6 +7) \times 17 = \frac{221}{2} = 110.5\; in^2[/tex]
Area of the figure = (Area of the triangle) + (Area of the trapezium)
= 10.5 in.² + 110.5 in.²
= 121 in.²

help please , i need the perimeter and area
Answer:
Area = 3.5325 ft² ≈ 3.53 ft²
Perimeter = 7.71 ft
Step-by-step explanation:
This is a semi-circle so we just divide the circumference of the original circle by 2
C = 2πr
C = 2 * 3.14 * 1.5
C = 3.14 * 3
C = 9.42
9.42 / 2 = 4.5 + 0.21 = 4.71 ft
4.71 ft + 3 = 7.71 ft
Area:
A = πr²
A = 3.14 * 2.25
A = 7.065 ft²
7.065 ft² = 3.5 + 0.0325 = 3.5325 ft²

Lines CD and DE are tangent to circle A, as shown below:
CE is 105°, what is the measure of angle CDE?
52.5°
62.5
75°
255°
Answer:
The correct answer is 75 dgrees
Step-by-step explanation:
<CDE = arcCBE - arcCE / 2
arcCE = 105°
arcCBE = 360° - 105° =255°
<CDE = 255° - 105°
<CDE = 150 / 2
<CDE = 75°
Therefore the measure of < CDE is 75°

a) Find the gradient of a line perpendicular to line AB.
Step-by-step explanation:
the gradient for the line perpendicular to AB is 3The slope of the line that is perpendicular to the line of AB is: 3.
What is the Slope of Perpendicular Lines?If two lines are perpendicular to each other, their slopes will be the negative reciprocal of each other. i.e., if the slope of one is 3, the slope of the other would be -1/3.
Slope = change in y / change in x
Slope of AB = (-2 - 2) / (7 -(-5))
Slope of AB = -4/12
Slope of AB = -1/3
Negative reciprocal of -1/3 would be 3.
Therefore, the slope of the line that is perpendicular to the line of AB is: 3.

7.5cm2
Step-by-step explanation:
5x3cm=15cm2 because of base x height/2 you would do
15cm2 divided by 2 since it is a triangle (a half of a square) which is 7.5cm2
Answer:
D.
Step-by-step explanation:
Area of a triangle is bh/2
So your base is 5 and your height is 3.
So you do 5*3 which is 15.
And lastly you do 15/2, which is 7.5. 7*2 is 14, and 8*2 is 16
So 7.5 times 2 is 15

2x= 30
Divide both sides by 2:
x= 15
Substituting the value of x:

What is the area of 9yd and 5yd and how’d you get it
9514 1404 393
Answer:
45 yd²
Step-by-step explanation:
The area of a rectangle is the product of its length and width. If your given measures are the length and with of a rectangle, the area is found by multiplying them.
A = LW
A = (9 yd)(5 yd) = 9·5 yd·yd = 45 yd²
The area of a 9 yd by 5 yd rectangle is 45 square yards.

2y+ 3x = 87 and y=6x+21
Answer:
x=3 and y=39
Step-by-step explanation:
2y + 3x = 87
y = 6x + 21
2(6x+21) + 3x = 87
12x + 42 + 3x = 87
15x + 42 = 87
15x = 45
x = 3
y = 6(3) + 21
y = 18 + 21
y = 39

Determine whether the lines given by the fallowing equations intersect at (-1/4,3/4) show all work. 4x+8y=5, x-3y= -3
Answer:
(0, 1)
Step-by-step explanation:
First, we need to make y the subject of the formula from both expressions
For 4x+8y=5
8y = 5- 4x
y = (5-4x)/5
Similarly for x-3y= -3
-3y = -3 - x
3y = x+3
y = (x+3)/3
Since both lines intersects, hence;
(5-4x)/5 = (x+3)/3
Cross multiply
5(x+3) = 3(5-4x)
5x + 15 = 15 - 12x
5x + 12x = 15 - 15
17x = 0
x = 0/17
x = 0
Sustitute x = 0 into any of the equations
Given that y = x+3/3
y = 0+3/3
y = 3/3
y = 1
This shows that the lines intesects at (0, 1)

8. Select all the numbers that irrational
Answer:
Answers are square root of 2, square root of 7,
Step-by-step explanation:
Irational is a number that is never ending.
Square root of 2 is irrational since there is no pattern to the number after the decimal.
10/ sqrt of 100. Sqrt of 100 is 10. 10/10 = 1 so this is not a irrational.
Sqrt of 7 does not have a pattern after the decimal point so it is irrational.
5.87 with a dash on top is rational since it means it has a pattern of continues 87's.
Last one it is equal to 2 so it is rattional.
Answer:
The square root of 2 is irrational, also 5.87 repeating, the square root of 7 and the other two options aren't irrational.
Step-by-step explanation:
Irrational numbers definition: a number that can be expressed as an infinite decimal with no set of consecutive digits repeating itself indefinitely and that cannot be expressed as the quotient of two integers
