Answers

Answer:

77.12 feets

Step-by-step explanation:

In a 33' by 69.7' room, what is the diagonal length from corner to corner along the floor?

Step one:

given data

Length of the room= 33 feets

width of the room = 69.7 feets

Required

The diagonal of the room

Step two:

from Pythagoras theorem

z^2= x^2+y^2

substitute

z^2= 33^2+ 69.7^2

z^2=1089+4858.09

z^2=5947.09

z=√5947.09

z=77.12 feets

A) V28
B) 500
C) 7162

Answers

Answer:

[tex]\sqrt{28} = 2\sqrt{7}[/tex]

[tex]\sqrt {500} = 10 \sqrt {5[/tex]

[tex]\sqrt {162} = 9 \sqrt {2[/tex]

Step-by-step explanation:

Given (Correct Parameters)

[tex]\sqrt {28[/tex]

[tex]\sqrt {500[/tex]

[tex]\sqrt {162[/tex]

Required

Express in simplified form

[tex]\sqrt {28[/tex]

Express 28 as 4 * 7

[tex]\sqrt{28} = \sqrt{4} * \sqrt{7}[/tex]

Take positive square root of 4

[tex]\sqrt{28} = 2 * \sqrt{7}[/tex]

[tex]\sqrt{28} = 2\sqrt{7}[/tex]

[tex]\sqrt {500[/tex]

Express 500 as 100 * 5

[tex]\sqrt {500} = \sqrt {100} * \sqrt {5[/tex]

Take positive square root of 100

[tex]\sqrt {500} = 10 * \sqrt {5[/tex]

[tex]\sqrt {500} = 10 \sqrt {5[/tex]

[tex]\sqrt {162[/tex]

Express 162 as 81 *2

[tex]\sqrt {162} = \sqrt {81} * \sqrt {2[/tex]

Take positive square root of 81

[tex]\sqrt {162} = 9 * \sqrt {2[/tex]

[tex]\sqrt {162} = 9 \sqrt {2[/tex]

An elementary school bus comes at 8:15 am every morning to pick up children in a neighborhood. The probability that the bus will be late is 0.19 and the probability that the bus will be early is 0.02.
What is the probability that the bus will arrive early next two days?
What is the probability that the bus will arrive on time next two days?
In two or more complete sentences, explain your calculations for parts A and B. In your explanation, include their similarities and differences.

Answers

Answer:

a. .02 * .02 = .0004  

b. (1 - .02 - .19) = .79; .79*.79 = .6241

Step-by-step explanation:

The probability that the bus will arrive on time next two days is 0.79, The probability that the bus will arrive early next two days is 0.0004.

What is Probability?

Probability is the likeliness of an event to happen, it has a range from 0 to 1.

Probability that the bus will be late is 0.19

Probability that the bus will be early is 0.02.

The probability that the bus will arrive early next two days is

= 0.02 * 0.02

=0.0004

The probability of coming early one day is small and the probability that it will come early two days in a row is smaller.

The probability that the bus will arrive on time next two days

= (1 - 0.02 -0.19) = 0.79

The probability that the bus will come on time is more as the probability of coming early or late is less.

Suppose y varies directly with x. Write a direct variation equation that relates x and y. Then find the value of y when x=16...
y=7 when x=2

Answers

Step-by-step explanation:

y = kx, where k is a real constant.

When x = 2, y = 7.

=> (7) = k(2), 2k = 7, k = 3.5.

Therefore when x = 16,

y = (3.5)(16) = 56.

The value of y is 56 when x is 16.

The formula for direct variation is y = kx

Using the known x and y solve for k:

7 = k2

Divide both sides by 2:

k =7/2 = 3.5

Now solve for y when x = 16:

y = 3.5(16)

y = 56

Melanie saves $20 every month in her savings account. She withdrew $60 one time to go shopping. She now has $280 in her account. write and solve an equation to determine how many months she has been saving up

Answer:

20x-60=280

Equation

So x for unknown amount of months, since 20 dollar each month 20x

-60 becuase she withdraws 60 one time

=280 becuase thats what she has left

Now solve

add 60 on both sides

20x=340

Divide 20 on both sides

F
is directly proportional to
a
.
If
F
=
36
when
a
=
9
find,
F
when
a
=
4

Answers

Step-by-step explanation:

F = ka, where k is a real constant.

When a = 9, F = 36.

=> (36) = k(9), k = 4.

Therefore when a = 4,

F = (4)(4) = 16.

The value of F is 16 when a is 4.
