If a wheel of a bicycle covers 440m in 200 rotation. find the area of a wheel.​

Answers

Answer 1

Answer:

7/22

Step-by-step explanation:

Area = 400/200 × 400/200 ×1/4 × 7/22 = 7/22

Answer 2

Step-by-step explanation:

Total distance covered in 200 rotation = 440 m

Distance covered in 1 rotation

= 440 / 200

= 2.2 m

Distance covered in 1 rotation = Circumference of circle so

circumference = 2πr

2.2 = 2 * 22/7 * r

2.2 = 6.28 r

r = 2.2 / 6.28

r = 0.35 m

Now Area of the wheel

= πr²

= 22 /7 * 0.35 * 0.35

= 0.385 m²

Hope it will help :)❤

Jacob has $25 worth of baseball trading cards. His sister, Bonita, has some trading cards and

his sister, Madison, has $7 worth of trading cards. Bonita cards are worth $2 each. Bonita's

and Madison's trading cards together are worth more than Jacob's cards. How many trading

cards, x, could Bonita have?

a) Write the inequality.

b) Solve the inequality using properties of operations.

c) Represent the solution(s) on a number line.

HHHHHHHHHHHHH

15

10

d) Use substitution to determine whether 8, 9, 12, or 15 are solutions to the inequality.

Answers

Answer:

2x + 7 > 25 ; 9

Step-by-step explanation:

Total worth of Jacob's cards = $25

Number of Bonita's card = x

Worth of Bonita's card = $2 each

Worth of Madison card = $7

Bonita and Madison cards are worth more than Jacob's card

The inequality

Bonita = 2x ; Madison = 7

2x + 7 > 25

Solving for x

2x > 25 - 7

2x > 18

x > 18 /2

x > 9

If a triangle has a right angle and a 30 degree angle, what is the measure of the third angle?

Answers

Answer:

60

Step-by-step explanation:

All triangles have a total measurement of 180 degrees. So to find the last angle measure subtract 90 and 30 from 180, 180-(90+30). This equals 60 degrees. Additionally, a triangle with a 90 and 30 degree angle is known as a 30-60-90 special right triangle. All of these triangles will have 60 as their third measurement.

I think the answer is 60 I’m not sure but good luck

Find the rule. Solve for n. Х Y 4 3 6 5 7 6 10 n Rule: ​

Answers

Answer:

n = 9

Step-by-step explanation:

Here we have the table:

X     Y

4     3

6    5

7     6

10   n

First, we want to find the rule.

in the first pair we have:

x = 4

y = 3

We can see that the y-value is one smaller than the x-value

y = 3 = 4 - 1 = x - 1

For the second pair we have:

x = 6, y = 5

We again can see that the y-value is one smaller than the x-value

y = 5 = 6 - 1 = x - 1

For the third pair we have:

x = 7, y = 6

Again, can see that the y-value is one smaller than the x-value.

y = 6 = 7 - 1 = x - 1

We can conclude that the rule is:

y = x - 1

For the last pair, we have:

x = 10, y = n

Then:

n = 10 - 1 = 9

n = 9

Then the table is:

X     Y

4     3

6    5

7     6

10   9

Halle el valor de "h" del punto centro de la ecuación de la circunferencia cuyo diámetro es el segmento de la recta que une los puntos A(2,3) y B(4,−1):

Answers

Answer:

El punto es (3, 1)

Step-by-step explanation:

Sabemos que la ecuación de un circulo centrado en el punto (a, b), con radio R, se escribe como:

(x - a)^2 + (y - b)^2 = R^2

En este caso, sabemos que el diametro de nuestro circulo es igual al segmento que uno los puntos A(2, 3) y B(4, -1) (y el diametro es el doble del radio)

Entonces el centro del punto es exactamente el punto medio en el segmento dado.

Para encontrar el punto medio en el segmento dado, tenemos que encontrar el punto medio entre los valors en x, y el punto medio entre los valores en y.

Donde el punto medio entre dos valores a y b se calcula como:

punto medio = (a + b)/2  

El punto medio en x es:

x = (2 + 4)/2 = 3

El punto medio en y es:

y = (-1 + 3)/2 = 2/2 = 1

Entonces el punto medio en el segmento es:

C(x, y) = C(3, 1)

Esto quiere decir que el centro de la circunferencia va a ser el punto (3, 1)

Oliver is performing an experiment by spinning a metal weight around on the end of a nylon thread. How far does the metal weight travel if it

completes 10 revolutions on the end of a 0.88 m thread?

Give your answer correct to one decimal place.

Answers

Answer:

27.7m

Step-by-step explanation:

Step 1

We find the Circumference of the nylon thread.

The formula = 2πr

The diameter of the thread = 0.88m

Radius = Diameter/2

= 0.88m/2

= 0.44m

Circumference = 2 × π × 0.44m

= 2.7646015352m

Approximately = 2.765m

Step 2

We calculate the distance

Number of revolutions = 10

Therefore, the Distance or how far the metal weight can travel =

Circumference of the wheel × Number of revolutions

= 2.765m × 10

= 27.65m

Approximately to 1 decimal place = 27.7m

Step-by-step explanation:

Solve for w over the real numbers:

4 w^2 + 8 w + 4 = 0

Divide both sides by 4:

w^2 + 2 w + 1 = 0

Write the left hand side as a square:

(w + 1)^2 = 0

Take the square root of both sides:

w + 1 = 0

If 30% of a number equals 25, find 60% of that number.

Answers

Answer:

14.94

Step by step:

 25/30 = 83.333

.30x83 = 24.9

.60 x 24.9 = 14.94

Answer:

50

Step-by-step explanation:

Let's set the number as "x". So, 30% of x is 25. We can then write this equation.

30% * x = 25

Change 30% to a decimal

0.3 * x = 25

Divide both sides by 0.3

x = 83 and 1/3

Then, to find 60% of this number, write this equation.

60% * 83 1/3 =

0.6 * 83 1/3 =

In 2007, the population of Tallahassee, Florida was 168,979. Some researchers believe that the population of Tallahassee will increase at a rate of 1% each year. If this is correct, how many years will it take for Tallahassee to reach a population of 180000. Round appropriately and write units. ​

Answers

Answer:

Number of year in which population will be 180,000 = 6 year (Approx.)

Step-by-step explanation:

Given:

Population in 2007 = 168,979

Rate of increase in population = 1% = 0.01

Future population = 180,000

Find:

Number of year in which population will be 180,000

Computation:

A = P[1+r]ⁿ

Future population = Population in 2007[1+Rate of increase in population]ⁿ

180,000 = 168,979[1+0.01]ⁿ

180,000 = 168,979[1.01]ⁿ

1.06522 = [1.01]ⁿ

n = 6 (Approx.)

Number of year in which population will be 180,000 = 6 year (Approx.)

Find the distance between y= 2/3x+4 and y=2/3x-1 1. Round your answer to the nearest tenth. The distance is about units.​

Answers

Answer:

12.5

Step-by-step explanation:

y= 2/3x+4 and y=2/3x-1 1 are parallel: slope 1 = 2/3 = slope 2

the distance of line 1 and line 2 is the segment length of perpendicular line intercept two parallel lines. In other words, the distance between two parallel lines in the plane is the minimum distance between any two points lying on the lines. It equals the perpendicular distance from any point on one line to the other line.

equation of the perpendicular line pass the y intercept of line 1: y=2/3x+4  (0,4) is y = -3/2x + 4, which intercept with line 1 at (0,4)

solve the intercept of perpendicular line with line 2: get (6.9 , -6.4)

    y=-3/2x + 4 and y=2/3x-1 1 (you should be able to solve this part by self)

distance of (0,4) and (6.9,-6.4): √(6.9-0)²+(-6.4-4)² = √155.77 = 12.48 ≈ 12.5
