A bag contains equal-sized disks that are either red, green, yellow, or blue. There are 6 red disks, 3 green disks, 6 yellow disks, and 5 blue disks. If a disk is selected at random from the bag, what is the probability that the disk will be either red or yellow?

Answer:

It would be D it is basically saying Z-6 =1.4

z =7.4

Answer:

The answer to this question is NOT B,

Step-by-step explanation:

The difference of a number and z is the same as one and four-tenths. A number subtracted from one and four-tenths is equal to six.

Answer:

A) About a 55% discount

WORK:

We can make an equation

89.99x=49.50

Where x is the percent discount

Now solve for X

You’ll get about 0.55

B) 53.46 with tax

WORK:

Mulitply 49.5 by 1.08

We can use 1.08 since the 49.50 is already the 100 percent and the 8 percent is just extra so when multiplied it should give you 53.46

Double check:

We can also just find 8 percent of 49.5 and get 3.96

When added, it should result in 53.46

Given:

Anita's fixed salary = Rs. W

Bonus = Rs. Z for every bedcover sold by her.

To find:

Her total earnings if she sold 46 bedcovers.

Solution:

We have,

Bonus if she sold 1 bedcover = Rs. Z

Bonus if she sold 46 bedcover = Rs. Z × 46

We know that,

Total earnings = Fixed salary + Bonus

                        = [tex]W+Z\times 46[/tex]

Therefore, the correct option is (b).

Answer:

The length of the runway =  12090 feet

Step-by-step explanation:

The formula involving the area of a rectangle is

[tex]A=wl[/tex]

here

Given

Area A = 1,934,400 square feet

Width w = 160 w

Length l = ?

Using the formula

[tex]A=wl[/tex]

substituting the values

1,934,400 = 160 × l

l = 1,934,400 / 160

l = 12090 feet

Therefore, the length of the runway =  12090 feet

Answer:

The total cost of ordering 4 tickets is $43.

Step-by-step explanation:

Let [tex]x[/tex] = number of tickets

The given expression to find total cost to order:

[tex]10x+3[/tex]

To find the total cost of ordering 4 tickets, simply substitute 4 for [tex]x[/tex] in the expression, and solve:

[tex]10(4)+3=[/tex]

[tex]43[/tex]

Therefore, the total cost of ordering 4 tickets is $43.

_

You can check your work by setting the given expression equal to 43:

[tex]10x+3=43[/tex]

Subtract [tex]3[/tex] from both sides of the equation:

[tex]10x=40[/tex]

Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]10[/tex]:

[tex]x=4[/tex]

This shows that the cost of ordering 4 tickets is in fact, $43.

Our solution is correct!

Step-by-step explanation:

Lin lines the bottom of her first pan with aluminum foil. The area of the rectangular piece of foil 11 1 4 is square inches. Its length is 4 1 2 inches. What is the width of the foil? Explain your reasoning.

Area of rectangle = Length × Width

Widths = Area/Length

The area of the rectangular piece of foil 11 1/4 is square inches.

Its length is 4 1 /2 inches.

Hence:

Length = 11 1/4 /4 1/2

= 45/4 ÷ 9/2

= 45/4 × 2/9

= 5/2 inches

= 2 1/2 inches

Answer:

16. d = distance

     r = rate

     t = time.

We know that the rate = 4, and time = 11.

=> d = 4 * 11

=> d = 44

17. We know that distance = 36, and time = 4.

=> 36 * r* 4

=> 36 = 4r

=> 36/4 = 4r/4

=> r = 9

Tip: solve the stuff inside the parentheses (17-12=5 and 8-(-2)= 10 because 2 negatives make a positive) and then multiply those answers by -8 and -2

Answer:

2

The fraction line means division.

Use PEMDAS (parenthesis, exponents, multiplication, division, addition, subtraction)

Anyways, parenthesis come first in PEMDAS, so:

-8(17-12)/-2(8-(-2))

= -8(5)/-2(10)

Next comes multiplication:

(The -8(5) is another way of -8 x 5)

-40/-20

Lastly, division:

(two negative signs make a positive)

40/20 = 2

Answer:

15 inches

Step-by-step explanation:

1. Use the Pythagorean Theorem: a^2+b^2=c^2

You are already given c (the longest side) and one of the legs which could be a or b.

2. Plug the numbers into the formula and square them.

a^2 + 36^2 = 39^2

Squaring the numbers gives you: a^2 + 1,296 = 1,521

3. Subtract 1,296 from both sides and take the square root of the result.

a^2 = 225

[tex]\sqrt{225}[/tex] = 15

Answer: 15

Step-by-step explanation:

Answer:

Step-by-step explanation:

The total fence the gardener should purchase is the perimeter of the triangle and is given by the equation P = 18 feet

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

Given data ,

Let the perimeter of the triangle be represented as P

P = total fence the gardener should buy

Let the triangle be represented as ΔABC

Now , the inner triangle is represented as ΔXYZ

And , The measure of XZ = 4 feet

The measure of XY = 2 feet

The measure of YZ = 3 feet

where X is the midpoint of AB

Y is the midpoint of BC

And , Z is the midpoint of AC

Now , AX = BX   be equation (1)

BY = CY   be equation (2)

AZ = CZ   be equation (3)

Now , from the triangle ,

XY = ( 1/2 ) BC

XY = ( 1/2 ) AC

YZ = ( 1/2 ) AB

Substituting the values in the equation , we get

The measure of BC = 8 feet

The measure of AB = 6 feet

The measure of AC = 4 feet

So , the perimeter of the triangle P = measure of BC + measure of AB + measure of AC

And , perimeter of the triangle P = 8 + 6 + 4

Perimeter of the triangle P = 18 feet

Therefore , the value of P is 18 feet

Hence , the fence around the triangle is 18 feet
