Bill's bike wheels have a 26-in. diameter. The odometer on his bike counts the number of times a wheel rotates during a trip. If the odometer counts 200 rotations during the trip from Bill's house to school, how many feet does Bill travel? Round to the nearest foot.
Answer:
1361 ft.
Explanation:
The circumference of the wheel times the number of rotations equals distance travelled
[tex]C = d\pi[/tex]
Answer:
≈ 1361 ftStep-by-step explanation:
One rotation is same distance as:
C = πd = 3.14*26 = 81.64 inTotal distance traveled:
200*81.64 = 16328 inConvert inches to feet:
12 in = 1 ft16328 in = 16328/12 ft = 1360.66666667 ft ≈ 1361 ftABCD is a parallelogram. Find the value of x, y and z.
Step-by-step explanation:
X+100=180(linear pair)

HELP PLSPPPPPPPPPPPPPPP
Answer:
The equation is following the mathematical rule of multiplying exponents.
Step-by-step explanation:
As an example to back up the answer, when you have half of a dollar, that is $0.50, if you took a half (1/2) of $0.50 that would be one fourth (1/4) of a dollar, but half of 50 cents ($0.50) A similar thing is happening with this problem. When you have two numbers (2 and 4) when you multiply them together, they equal to eight (8) for this problem, when you multiply two exponents together, you are raising the coefficient (a real number like 6) to the power of 2, and then taking that number and multiplying it by the power of 4. This is similar to the half of 50 cents, is equal to 1/4 of dollar ($0.25)
Hope this helps explain multiplying exponents together, and the mathematical rule behind it.

the equilateral triangle and the rectangle have the same perimeter.
triangle: 2.5x + 10. rectangle: x +12 + 8x
what is the value of x?
what is the perimeter of the rectangle?
Answer: x = - 4/13
Step-by-step explanation:
2.5x+10=x+12+8x
10-12 = x+8x-2.5x
-2 = 6.5x
x = -4/13
please help i’m failing algebra and it’s only the 3rd week
1) One fifth of the sum of two angles is 36° and half of the difference between the two angles is 40°. Find the size of the two angles.
6) The price of 6 chairs and 3 tables is RM480. The price of 8 chairs and a table is RM400. Find the price of a chair and a table.
7) The sum of Wan Yee's and her mother's age is 60. Two years ago, her mother was three times older than Wan Yee. Calculate (a) Wan Yee's age now.
(b) her mother's age when she was born.
Answer:
1) 130 degrees and 50 degrees 6) a price of a chair is 40, a price of the table is 80 7) a) 16 b)28
Step-by-step explanation:
1) Let it be that the first angle is x, The second one is y
1/5(x+y)=36- the first equation
1/2(x-y)=40- the second equation
The equations are simultaneous
x+y=180 and x-y=80
x+y+x-y=180+80
2x=260
x=130
y=50
6) The cost of a chair is x, the cost of table is y
6x+3y=480 2x+y=160
8x+y=400
8x+y- (2x+y)=400-160
6x=240
x=40
2*40+y=160
y=80
7) The Wan's age is x, the mother's age is y
x+y=60 x=60-y
Two years ago mother's age was y-2, when Wan;s age was x-2
y-2=(x-2)*3
y-2= (60-y-2)*3
y-2= (58-y)*3
y-2=174-3y
4y=176
y= 44
x=60-44=16- Wan's age now
44-16=28- her mother's age when she was born
what is 384757 + 293
Part A Find the value of x
x=20
x=35
x=70
x=110
Part B Find the measure of the unlabeled angle in the previous question
40°
70°
110°
140°
Answer: x = 35
Step-by-step explanation: The sum of all the angles is equal to 360.
2*(x+y+5)+y+2x=360
Opposite angles are equal: y = 2x
Substitute y=2x into the first: 4x+6x+10 = 360: x=35 (y = 70)

What is the Triangle Congruence Theorem and is it congruent?
Answer:
Two triangles are congruent if their corresponding sides are equal in length and their corresponding interior angles are equal in measure. We use the symbol ≅ to show congruence. Corresponding sides and angles mean that the side on one triangle and the side on the other triangle, in the same position, match.Step-by-step explanation:

Graph the equation: g(x) = 5 - 2x
So first you could need to find the x and y intercepts.
So the x intercept can be found why y is zero and vice versa.
so your graph would go through the points (0,5) and (2.5,0)
This is confusing and makes no sense

A is the answer

Given the following functions:
f(x) = x2
g(x) = 2 x - 3
Find the composition of the two functions and show your process:
f(g(x))
Answer:
f(g(x)) = 4x² - 12x + 9
Step-by-step explanation:
Substitute x = g(x) into f(x) , that is
f(g(x))
= f(2x - 3)
= (2x - 3)² ← expand using FOIL
= 4x² - 12x + 9

I’ve been stuck on the same question for days now
Answer:
7
Step-by-step explanation:
You've said that both triangle are equal.
This means, both are in proportion
Let the unknown side be x
4 : 5 : x = 36 : 45 : 63
Divide LHS by 9
4 : 5 : x = 4 : 5 : 7
Since you may see x and 7 are same. So, the missing side is 7.
Answer:
Step-by-step explanation:
[tex]\frac{AB}{PQ} = \frac{BC}{QR}[/tex] #1 Find same sides
So, [tex]\frac{4}{36} =\frac{BC}{63}[/tex] #2 fill it in.
36BC= 252 #3 Cross multiply.
[tex]\frac{36BC}{36}[/tex]= [tex]\frac{252}{36}[/tex] #4 Divide by 36
BC= 7 #5 Here's your answer!
If you want to check, plug the sides in.
[tex]\frac{4}{36} =\frac{5}{45} =\frac{7}{36}[/tex]
[tex]\frac{1}{9} =\frac{1}{9} =\frac{1}{9}[/tex]
The siplified fractions should all equal the same number. If they do, the triangles are similar.
