What is the area of this quadrilateral?
8 ft
6 ft
3.ft
A. 33 square feet
B. 42 square feet
C. 17 square feet
D. 66 square feet

Answers

Answer:

a. 33 sqft

Step-by-step explanation:

The figure is made of two non-overlapping triangles, so the total area is the sum of the areas of the two triangles

Area of a triangle is 1/2(bh) where b = base length and h = height (b and h must be perpendicular to each other)

The top triangle has b = 6 and h=8, so A=1/2(6)(8) = 1/2(48) = 24

The bottom triangle has b=6 and h=3, so A=1/2(6)(3)=1/2(18) = 9

Total area is sum of these two or 24 + 9 = 33

x-4y=-4
5x – 4y= 12

Answers

Answer: {x,y} = {4,2}

  [1]    x - 4y = -4

  [2]    5x - 4y = 12// Solve equation [1] for the variable  x

 [1]    x = 4y - 4

// Plug this in for variable  x  in equation [2]

  [2]    5•(4y-4) - 4y = 12

  [2]    16y = 32

// Solve equation [2] for the variable  y

  [2]    16y = 32

  [2]    y = 2

// By now we know this much :

   x = 4y-4

   y = 2

// Use the  y  value to solve for  x

   x = 4(2)-4 = 4

Step-by-step explanation:

Answer: x=4 y=2

Step-by-step explanation:

y is directly proportional to x.
when y=30, x=6
work out an equation connecting y and x

Answers

Answer:

y = 5x

Step-by-step explanation:

Use the direct variation equation y = kx

Plug in 30 as y and 6 as x, then solve for k

y = kx

30 = k(6)

5 = k

Plug in 5 as k into y = kx

y = 5x

So, the equation relating x and y is y = 5x

Answer:

y=5x

Step-by-step explanation:

30 divide by 6 = 5 so y = 5x

Mason used a 30% coupon to buy a new computer. After the discount, the cost of the computer was 728. Determine the original price of the computer. Calculate how much money mason saved by using the coupon.

Answers

Answer:

Mason saved $312.00.

Step-by-step explanation:

This is because, if you multiply the original price by 30%/100 or $1040 x 0.3 you get $312.00. So basically, multiply the original price by the discount number over 100 you get your answer.

The percentage is calculated by dividing the required value by the total value and multiplying it by 100.

The original price of the computer is 1040.

The amount saved by Mason using the coupon is 312.

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying it by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

We have,

Coupon = 30% off

Cost of the computer after the coupon = 728

This means that the cost of the computer is only 70% since 30% is off.

70% = 728

We know that the original price is 100%.

So,

70% = 728

Multiply 100/70 on both sides.

100/70 x 70% = 100/70 x 728

100% = 1040

The original price of the computer is 1040

The amount saved is:

= 1040 - 728

= 312

Thus,

The original price of the computer is 1040.

The amount saved by Mason using the coupon is 312.

The ratio of the number of fiction books to the number of non-fiction books in a library is 8:5. There are 678 more fiction books than non-fiction books. How many non-fiction books are there in the library?​

Answers

Answer:

1130 non fiction

Step-by-step explanation:

F=fiction

NF=non fiction

F-678=NF

5F=8NF

so NF=5/8F

substitute:

F-678=5/8F

reduce:

3/8F=678

F=1808

NF=1130

There are 1130 non fiction books in the library.

Given that,

Ratio of fiction books (F) to non fiction books (NF) is 8:5.678 more fiction books in library.We need to find the number of non fiction books.

According to the scenario, calculation of data are as follows,

[tex]\frac{F}{NF} = \frac{8}{5}[/tex]

or 5F = 8NF

Now, NF = F-678

By putting the value, we get

5F = 8 ( F - 678)

5F = 8F - 5424

3F = 5424

F = 1808

So, By putting in 1st eq. we get,

NF = 9040 [tex]\div[/tex] 8

NF = 1130

Probability simply means the chance that a particular thing or event will happen. It is the occurence of likely events. It is simply the area of mathematics that deals with the numerical estimates of the chance that an event will occur

It should be noted that this relates to a binomial probability. This is Illustrated as:

n! / x! (n - x)!

n = number if questions = 4

The probability will be:
