Question 7 Of 10What Is The Length Of BC In The Right Triangle Below?

Answers

Answer 1

Answer:

A

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

BC² = 9² + 12² = 81 + 144 = 225 ( take the square root of both sides )

BC = [tex]\sqrt{225}[/tex] = 15 → A

2. Bats are mammals that can fly.
3. You are a good citizen when you obey rules and regulations.
4. A number is divisible by 10 if its last digit is a 0.
5. 3x + 6 = 21, because x = 5​

Answers

Step-by-step explanation:

To find - Determine the hypothesis and the conclusion of the given

               statement  the hypothesis in Box A and the conclusion in Box B.

             1. Vertical angles are congruent

             2. Bats are mammals that can fly.

             3. You are a good citizen when you obey rules and regulations.

             4. A number is divisible by 10 if its last digit is a 0.

             5. 3x + 6 = 21, because x = 5​

Proof -

Firstly we will write the conditional statements , so that we can easily find the hypothesis and the conclusion of the given statement.

1.)

Given statement - Vertical angles are congruent

Conditional statement - If two angles are vertical , then they are congruent.

Hypothesis - Two angles are vertical

Conclusions - They are congruent.

2.)

Given statement - Bats are mammals that can fly

Conditional statement - If bats are mammals , then they can fly.

Hypothesis - Bats are mammals

Conclusions - They can fly.

3.)

Given statement - You are a good citizen when you obey rules and regulations.

Conditional statement - If you are a good citizen , then you obey rules and regulations.

Hypothesis - You are a good citizen

Conclusions - You obey rules and regulations.

4.)

Given statement - A number is divisible by 10 if its last digit is a 0.

Conditional statement - If a number is divisible by 10, then its last digit is a 0.

Hypothesis - A number is divisible by 10

Conclusions - Its last digit is 0.

5.)

Given statement - 3x + 6 = 21, because x = 5​

Conditional statement - If 3x + 6 = 21, then x = 5

Hypothesis - 3x + 6 = 21

Conclusions - x = 5

A group of people went to a coffee shop.

Each person chose a drink and a treat.


number of people who chose coffee: number of people who chose tea = 1:4


Of those who chose coffee,

number of people who chose a muffin number of people who chose a tart = 2:7


Of those who chose tea,

number of people who chose a muffin : number of people who chose a tart = 5:1


What fraction of the people chose a tart?

Answers

Answer:

Fraction of the people chose a tart = [tex]\frac{13}{45}[/tex]

Step-by-step explanation:

Given - A group of people went to a coffee shop. Each person chose a

            drink  and a treat. number of people who chose coffee: number of  

            people who chose tea = 1:4. Of those who chose coffee,  number of  

            people who chose a muffin number of people who chose a tart =    

            2:7. Of  those who chose tea,  number of people who chose a muffin  

            : number of people who chose a tart = 5:1.

To find - What fraction of the people chose a tart?

Proof -

Let the Total number of People went to a coffee shop = 5x

Now,

As given, number of people who chose coffee: number of people who chose tea = 1:4

⇒Total number of people who chooses coffee = [tex]\frac{1}{5}.5x[/tex] = x

  Total number of people who chooses tea  = [tex]\frac{4}{5}.5x[/tex] = 4x

Now,

As given,

Of those who choose coffee,  number of people who chose a muffin number of people who chose a tart = 2:7

⇒Total number of people who choose muffin after coffee = [tex]\frac{2}{9}x[/tex]

   Total number of people who choose tart after coffee = [tex]\frac{7}{9}x[/tex]

Also,

Given that

Of those who chose tea,  number of people who chose a muffin : number of people who chose a tart = 5:1

⇒Total number of people who choose muffin after tea = [tex]\frac{5}{6}.4x = \frac{20}{6}x[/tex]

   Total number of people who choose tart after tea = [tex]\frac{1}{6}.4x = \frac{4}{6}x[/tex]

∴ we get

Total number of people who chooses tart = Total number of people who choose tart after coffee + Total number of people who choose tart after tea

⇒Total number of people who chooses tart = [tex]\frac{7}{9}x[/tex] + [tex]\frac{4}{6}x[/tex]

                                                                         = [tex]\frac{7}{9}x + \frac{2}{3}x[/tex]

                                                                         = [tex]\frac{7x + 6x}{9}[/tex]

                                                                         = [tex]\frac{13}{9}x[/tex]

⇒Total number of people who chooses tart = [tex]\frac{13}{9}x[/tex]

Now,

Fraction of the people chose a tart = [tex]\frac{People choose tart}{Total people}[/tex]

                                                           = [tex]\frac{\frac{13}{9}x }{5x}[/tex]

                                                           = [tex]\frac{13}{45}[/tex]

⇒Fraction of the people chose a tart = [tex]\frac{13}{45}[/tex]

In 2003 a gallon of gas cost $1.75. The cost has risen $0.17 each year since then
Write an equation to represent the cost of gas (in gallons) as a function of years.
What would the cost of a gallon of gas be in 16 years?

Answers

Answer:

x + m × y

$4.47

Step-by-step explanation:

The equation and computation is shown below:

Let us assume the cost of gallon be x

Increase each year be m

And, the number of years be y

So, the equation is

= x + m × y

The cost of gallon of gas in 16 years is

= $1.75 + $0.17 × 16

= $1.75 + $2.72

= $4.47

Answer:

D  

Step-by-step explanation:

Two lines are parallel if they have the same slope.

the given equation is in the form

y=mx+b

where

m=-5/2

b=-7

m is the slope.  You can see this by noting that if you increase x by 1 you increase y by m.

So, in this case, you are looking for a line with slope of -5/2.

You can solve each of the choice equations for y to see which one has the right slope.

A: y=(2/5)x-6   no good

B: y=-(2/5)x-1   no good

C: y=(5/2)x-4   no good

Step-by-step explanation:

r (radius of circle) = 7 ft

pi = 3.14 (in this context)

v = 1/3 * [tex]πr^{2}[/tex] (or pi * radius squared) * h

r squared = 49 ft

v = 1/3 3.14 * 49 * h

v = 1/3 153.86 * h

3v = 153.86 * h

v = 196π

v = 615.44

3v = 1,846.32

1,846.32 = 153.86 * h

h = 12 ft.
