Find the diameter of the wheel. 0.6ft
Answer:
Diameter of the wheel = 1.2 feet
Step-by-step explanation:
Radius of a wheel = Distance between a point on the circumference and the center of the circle
Diameter of a wheel = 2(radius of the circle)
= 2(0.6)
= 1.2 feet
Therefore, diameter of the wheel is 1.2 feet.
If P = (-1,-1), find the image
of P under the following rotation.
270° counterclockwise about the origin
([?], [])
Enter the number that belongs in
the green box.
Enter
=========================================================
Explanation:
The rotation rule we use is [tex](x,y) \to (y, -x)[/tex]
The x and y coordinates step places, then the second coordinate (after the swap) changes in sign from positive to negative, or vice versa.
For example, the point (5,7) rotates to (7, -5). As another example, (2,-1) becomes (-1, -2). As another example, (-9,4) becomes (4,9).
----------------------------------
In our case, the point (-1,-1) will rotate to (-1, 1)
Note: A 270 degree counterclockwise rotation about the origin is the same as a 90 degree clockwise rotation about the origin. Refer to the diagram below.

Sara makes some Blue paint. She mixes yellow, red and brown in the ratio 4: 6: 9. He uses 340 ml of the yellow paint. How much Blue paint does he make?
Answer:
1615
Step-by-step explanation:
the equation that represents the amount of yellow paint used =
(ratio of yellow paint / sum of ratios) x p = 340
p = blue paint
4 / 19 x p = 340
p = 1615
There are 30 people entered into a contest. How many ways can the contestants win first, second, third, and fourth place?
Answer:
I am not entirely sure so don't kill me if it's wrong qwq
Step-by-step explanation:
Well assuming P represents the number of outcomes, n the number of competitors and r the number of places to be awarded.
P = n!
(n−r)!
P=30! /
(30-4)!
P=30!/26!
P=657720

Step-by-step explanation:
Write the equation of the circle with center (0, 0) and (3, 6) a point on the circle.
Answer:
Step-by-step explanation:
We will use the standard form of a circle to solve for the radius and then fill it back in. h is 0, k is 0, x is 3, and y is 6:
[tex](3-0)^2+(6-0)^2=r^2[/tex] and
[tex]3^2+6^2=r^2[/tex] and
[tex]9+36=r^2[/tex]
Therefore, r-squared is 45, so the circle's equation in standard form is
[tex](x-0)^2+(y-0)^2=45[/tex] or more simply:
[tex]x^2+y^2=45[/tex]

Answer:
28. x = 3 31. x = -3
Step-by-step explanation:
4x=12
divide both sides by 4
4x/4 = 12/ 4
x = 3
x/-3 = 1
multiply both sides by -3
x/-3 (-3) = 1 (-3)
simplify both sides
x = -3
Writing a linear equations
Answer:
y = -4x + 5
Step-by-step explanation:
Equation of the line can be written as y = mx + b (slope-intercept form)
Where m = slope and b = y-intercept of the line.
Let's find m and b of the line
Slope (m) using the points (1, 1) and (0, 5),
Slope (m) = change in y/change in x
m = (5 - 1)/(0 - 1) = 4/-1
m = -4
Find b:
b = the point where the line cuts the y-axis = 5 (y-intercept)
To write the equation substitute m = -4 and b = 5 into y = mx + b
y = -4x + 5
what is the missing exponent?
17 / 17^4 = 17^8
Answer:
The missing exponent is 12.
Step-by-step explanation:
Whenever you divide same-base exponents, you keep the base numbers the same and subtract the exponents.
The only number subtracted by 4 that would give you 8 is 12.
Or, if the numbers are larger, it is must easier to add the exponent in the answer to the number in the equation.
For example,
[tex]17^4+17^8=17^1^2[/tex]
Therefore, the missing exponent is 12.
Because: [tex]17^1^2/17^4=17^8[/tex]

Answer:
Option 'a' is the correct answer.
The school chess team must raise mora than $300 to attend a regional chess competition. Complete the inequality below to represent this condition.
Answer:
a > $300
Step-by-step explanation:
Note that
> means greater than
< means less than
≥ means greater than or equal to
≤ less than or equal to
for example : 2 < 3 means 2 is less than 3
3 >2 means 3 is greater than 2
the school must raise greater than $300 so the sign to be used is >
let the amount = a
a > $300
In the 2004 Summer Olympics, Adam van Koeverden of Oakville, Ontario, won two medals. He won the gold medal in the men’s 500 m kayak race, with a time of 1 min 37.9 s. He also won the bronze medal in the 1000 m race, with a time of 3 min 28.2 s. In which race did he row with greater speed?
Answer: 500 meters
Step-by-step explanation:
Since he won the gold medal in the men’s 500 m kayak race, with a time of 1 min 37.9 s, the speed will be:
= Distance/Time
= 500m/1 min 37.9s
= 500m/97.9s
= 5.11m/s
Since he also won the bronze medal in the 1000 m race, with a time of 3 min 28.2s, the speed will be:
= Distance/Time
= 1000/3 min 28.2s
= 1000m/208.2s
= 4.80m/s
Therefore, he rowed with greater speed in the 500 meters.
Note that 60seconds = 1 minute
What is the measure of the radius of the cone in the diagram below?
X
6 cm
8 cm
3 cm
4 cm
ОООО
6 cm
8 cm
Answer:
Option (2)
Step-by-step explanation:
Radius of the circular base of the cone = [tex]\frac{1}{2}(\text{Diameter of the circular base})[/tex]
Given in the picture,
Diameter of the circular base = 8 cm
Height of the cone = 6 cm
Therefore, radius of the cone = [tex]\frac{8}{2}[/tex]
= 4 cm
Option (2) will be the correct option.

Answer:
[tex]\implies x = (-2) \qquad or\qquad x = \dfrac{-3}{2}[/tex]
Step-by-step explanation:
Given :-
A quadratic equation is given to us.The equation is 2x² + 7x +6=0And we need to find out the roots of the given equation. We can use the middle term splitting method to find out the roots as ,
Given equation :-
[tex]\implies 2x^2 + 7x +6=0[/tex]
Step 1: Find out the factors of 12 :-
We will choose the two factors such that their sum equals to the coefficient of x i.e. 7 .The factors are , 1×12 , 2×6 , 3×4 .
And 3 + 4 = 7. So we will break the middle term into 3x and 4x .Step 2 : Breaking the middle term :-
[tex]\implies 2x^2 + 3x+4x +6=0[/tex]
Step 3: Take out common from terms :-
[tex]\implies x(2x + 3) +2(2x +3)=0[/tex]
[tex]\implies ( x +2)(2x+3)=0 [/tex]
Step 4 : Equate them with 0 :-
[tex]\implies x = (-2) \qquad or\qquad x = \dfrac{-3}{2}[/tex]
Hence the correct options are C and D .
