the diameter of a bike wheel is 25 inches. If the wheelmakes 20 Complete rotations, how far does the bike travel?
Answer:
1571 in
Step-by-step explanation:
Given data
Diamter= 25 in
radius= 25/2= 12.5in
Circumference= 2πr
substitute
C=2*3.142*12.5
C=78.55in
In 1 revolution the bike will travel 78.55in
in 20 revolutions the bike will travel
=78.55*20
=1571 in
Luis is 0.25 meters shorter than Harry, if Luis is 1.7 meters tall determine Harry’s height.
Answer: 1.95
Step-by-step explanation:
Luis is Harry's height minus 0.25m, which means Harry is Luis' height plus 0.25m.
Luis + 0.25 = Harry
1.7 + 0.25 = 1.95 m

What is the length of DE ?
Answer:
A. 6
Step-by-step explanation:
On triangle ZYX divide each side by 3 to get 4-4-3. Then multiple each side by 2, to get 8-8-6. That would mean DE is 6.
Please answer correctly and no giving links.
I need help Please help thank you <3
Answer:
Step-by-step explanation:
We start by finding what is inside the parenthesis, following the rules of pemdas we do 10 to the 6th power first, which comes out to be 1000000, we substitute this in instead of 10 to 6.
so we now have:
800.5x(2x1000000 )
Than finishing the parenthesis we multiply by 2
800.5x 2000000
than all you do is convert 800.5 to a decimal and 2000000 to an exponent, your teacher should have given you a chart or step by step directions for this part.

The sum of two numbers is 11. Twice the first number minus the second number is 7
Find the numbers.
Answer:
6 and 5
Step-by-step explanation:
6 * 2 = 12
12 - 5 = 7
6 and 5 is your answer
Answer: 6; 5
Step-by-step explanation:
Based on the questions, we set up two equations, let the x be the first number, and y be the second number.
x + y = 11
2x - y= 7
x = 11 - y [Subtract y from both side]
2x - y = 7
2(11 - y) - y = 7 [Plug in 11-y for x, solve for y]
22 - 2y - y = 7
22 - 3y = 7
-3y = -15 [Subtract 22 from both side]
y = 5
x + y = 11 [Plug in 5 for y, solve for x]
x + 5 = 11 [Subtract 5 from both side]
x = 6

Answer:
Step-by-step explanation:
The total number of triangles is 5
The total number of all shapes is 13
The ratio is triangles to total
The ratio is 5 to 13
Note
This problem is not very well defined. Notice the circle at the bottom left. It's less than 1/2 a circle. Question: do you count it or don't you. The answer to that question will influence other partial figures.
All you do is count the total number of figures and the number of triangles. I did count the part circle on the lower left as with the triangles that are missing their tops.

Mrs. Berry is purchasing a juicer which regularly sells for $390. She has a coupon for a 25% discount. The sales tax in her area is 7.5%. What will be the final cost of the juicer?
A $104.81 B $419.25 C. $314.44 D. $392.38
Answer:
C. $314.44
Step-by-step explanation:
$390 x 0.25 Discount = $97.5
$97.5 x 1.075 Sales Tax = $104.81 <---this is how much you save
$390 - $104.81 = $314.44 Total Price
Savings: $104.81
Tax: $21.94

pls answer
Answer:
width = 126 ft
Step-by-step explanation:
I'm going to assume that I am solving for width.
Area = width x length
84 = 2/3 x width
Now divide 84 by 2/3 to get the width (when you divide by a fraction, you actually multiply by its reciprocal, so it is 84 times 3/2)
84 x 3/2 = width
width = 126 feet

A system of equations is shown. 4x + 2y = 10
2x - 2y = 8
What is the value of x in the solution to the system?
Answer:
x=2
Step-by-step explanation:
2 (4x+2y=10 8x+4y=20
-4 (2x-2y=8 -8x+8y=-32
12y=-12 y=1
4x+2=10
4x=8
x=2
In the system's answer, x has the value of 3.
What are Systems of equations?Simultaneous equations, a system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.
There are four methods for solving systems of equations: graphing, substitution, elimination, and matrices.
We can solve this system of equations using the elimination method.
To eliminate y, we can add the second equation to the first equation. This gives:
(4x + 2y) + (2x - 2y) = 10 + 8
Simplifying the left side and combining the constants on the right side, we get:
6x = 18
Dividing both sides by 6, we get:
x = 3
Therefore, the value of x in the solution to the system is 3.
