Answer:

20 ft² - 4ft² = 16 ft²

Step-by-step explanation:

First we solve for the whole rectangle:

Formula:  A = ab

side length a = 5 in

side length b = 4 in

diagonal p = q = 6.4031242374328 in

perimeter P = 18 in

area A = 20 in²

Second we deduct the Area of the cutout of the Square

side length a = 2 ft

Area = a² = 4 ft²

What times 20% equals $70,000

Answers

just divide 70000 by .2 and you get 350000
you change the percentage in a number - 20% ÷ 100 = 0.2
∴ 70,000 ÷ 0.2 = the answer

Julie has 1,429 reward points from shopping at an online store. She uses the points to buy gift cards for free cups of coffee. Each card costs 150 points.What is the greatest number of gift cards Julie can buy?
How many reward points will she have left?

Answers

Answer:

Julie can buy 9 gift cards and will have 79 reward points left over

Step-by-step explanation:

If you divide 1,429 by 150, the number before the decimal, 9, is how many she can buy without exceeding her limit

Then, multiply 9 and 150 to see how many points 9 gift cards is worth (1350)

Subtract 1429-1350 to find the leftover points (79)

Which image (A'B'C'D') of ABCD cannot be produced using only reflection?

Answers

The image (A'B'C'D') of ABCD , in Option C cannot be produced using only reflection.

What is an Image of a Figure ?

Image is the copy of a figure made along the axis.

The figure attached as two figures , object and  image ,the image  has some transformation done to it

Figure 1 , option 1 :

In the figure

Object Coordinates :

ABCD : ( -6 ,4) , (-6,6) , (-2,6) , (-4,4)

A'B'C'D' : ( 6,-4) , (6,-6) , (2,-6) , (4,-4)

Figure 2 :

Object Coordinates :

ABCD : ( -6 ,4) , (-6,6) , (-2,6) , (-4,4)

A'B'C'D' : ( 4 , -6) , (6,-6) , (6,-2 ) , (4,-4)

Figure 3

Object Coordinates :

ABCD : ( -6 ,4) , (-6,6) , (-2,6) , (-4,4)

A'B'C'D' : ( 6 , -6) , (6,-4) , (2,-4 ) , (4,-6)

Figure 4

Object Coordinates :

ABCD : ( -6 ,4) , (-6,6) , (-2,6) , (-4,4)

A'B'C'D' : (4 , 6) , (6,6) , (2,6 ) , (4,4)

As all the image formed is just by reflection except of Option C , Figure 3.

Therefore Option C is the answer.

Rewrite f(x) = –2(x − 3)2 + 2 from vertex form to standard form. pleae help.

Answers

f(x) = -2(x - 3)² + 2
f(x) = -2(x - 3)(x - 3) + 2
f(x) = -2[x(x - 3) - 3(x - 3)] + 2
f(x) = -2[x(x) - x(3) - 3(x) - 3(-3)] + 2
f(x) = -2(x² - 3x - 3x + 9) + 2
f(x) = -2(x² - 6x + 9) + 2
f(x) = -2(x²) - 2(-6x) - 2(9) + 2
f(x) = -2x² + 12x - 18 + 2
f(x) = -2x² + 12x - 16
f(x)=-2(x-3)2+2=f(x)=-2(x-3)

38% convert into fraction

Answers

To convert a percentage into a fraction, we must first convert the percentage into a decimal. We can do that by either dividing the percentage by 100, or (my personal shortcut) just shifting the decimal point over two places to the left.

38% = 0.38

Now, all we need to do to convert it into a fraction is put the numbers to the right of the decimal point above a multiple of ten with as many zeros as there are numbers to the right of the decimal point. In this case:

0.38 = (38)/(100)

Now, all we need to do is reduce to find our fraction.

38 and 100 are both divisible by 2, so we will start off by doing that.

(38 / 2)/(100 / 2) = (19)/(50)

And that is our answer.
38% in fraction form is (19)/(50).
