Mathematics
1 answer:
Lapatulllka [165]3 years ago
7 0

Answer:  62.83 m

<u>Step-by-step explanation:</u>

The distance of one rotation is the perimeter of the wheel <em>(which is called "circumference" since it is in the shape of a circle)</em>

Circumference (C) = 2 π · radius (r)

C = 2π (10)

  = 20π

  ≈ 62.83

In a football tournament, the Bees scored 9 less than three times as many points as the Hornets. The Wasps scored 28 more points
Alinara [238K]

Answer:

  • <u>The Bees scored 90 points.</u>

Explanation:

First, let's prove that the equation is correct.

To create the equation, you translate the verbal statements into algebraic expressions.

Since, it is said that x respresents the number of points scored by the Hornets, that is your variable and all the verbal statements will be translated using x:

a) NUmber of points scored by the Hornets: x

b) The Bees scored 9 less than three times as many points as the Hornets ⇒v3x - 9

c) The Wasps scored 28 more points than the Hornets ⇒ x + 8

d) Together the three teams scored 184 points ⇒

 

  • x + (3x - 9) + (x + 28) = 184

Which indeed is the given equation: (3x – 9) + x + (x + 28) = 184

Now, complete the steps to show it, in the same order given:

<u>1. Combine like terms. </u>

  • Remove the parenthesis: x + 3x - 9 + x + 28 = 184

  • Combine the terms on x on the left: x + 3x + x = 5x

  • Combine the constants on the left: - 9 + 28 = 19

  • Write the result: 5x + 19 = 184

<u>2. Use the subtraction property of equality. </u>

  • Subtract 19 from both sides: 5x + 19 - 19 = 184 - 19

  • Due the operations: 5x = 165

<u>3. Use the division property of equality. 4. </u>

  • Divide both sides by 5: (5x / 5) = 165 / 5

  • Due the operations: x = 33

<u>4. Use the variable to answer the question. How many points did the Bees score?</u>

  • The expression for the points scored by the Bees is 3x - 9, so substitute x in that expression: 3 (33) - 9 = 99 - 9 = 90.

  • Answer: the Bees scored 90 points.

Write −12 as a ratio of two integers. <br><br> Enter your answer as a reduced improper fraction.
nikklg [1K]

Answer:

Assuming there are no other parts,

the Whole = A + B is the denominator:

Whole = 3 + 9 = 12

Part A = 3 and Part B = 9 are numerators for each fraction.

The fractions are then:

3/12 and 9/12

Meaning:

Part A is 3/12 of the whole

Part B is 9/12 of the whole

Reducing the fractions, it is also true that:

Part A = 1/4 of the whole

Part B = 3/4 of the whole

Butoxors [25]

Answer:

The route from A to the corner to B is longer then going directly from A to B. It is roughly 1.6 miles longer.

Step-by-step explanation:

The distance from A to the corner to B is 5.9 miles because

3.8 + 2.1 = 5.9

Going directly from A to B is roughly 4.3 miles because of

{a}^{2}   + {b}^{2}  =  {c}^{2}

5.9 - 4.3 = 1.6
