Answer:

Decimal: 0.80      Reduced fraction: [tex]\frac{4}{5}[/tex]

Step-by-step explanation:

Take 80% and move the decimal two place values to the left.

This makes 0.80              (The decimal point is where the percent sign is.)

0.80 is [tex]\frac{8}{10}[/tex]  because the 8 is in the tenths place value.

[tex]\frac{8}{10}[/tex] can be simplified by dividing both the numerator and the denominator by 2.

[tex]\frac{8}{10}[/tex] = [tex]\frac{4}{5}[/tex]

Answer:

2/6 or 33.33%

Explanation:

There are 6 numbers all together and 2 of them are 20$.As a fraction this would look like 2/6. 2/6 is also 33.33% of the wallet and its also the probability of pulling out a $20 bill

The probability that they are both $20 bill when There are two 20's, one 10, two 5's, and one 1 is to be considered as the 33.33%.

Since

You randomly choose two bills from your wallet.

And, there is 6 numbers

So, the probability is

[tex]= 2\div 6[/tex]

= 33.33%

Hence, The probability that they are both $20 bill when There are two 20's, one 10, two 5's, and one 1 is to be considered as the 33.33%.

:Reflected along x axis

Translated 7 units to the righ

A transformation of a point is the movement of the point from its initial position to a new position. If an object is transformed, all its points are also transformed. Types of transformation are reflection, rotation, dilation and translation.

Figure ABCD has A at (- 4, 4), B at (- 2, 2), C at (- 2, - 1), D at (- 4, 1).

If a point (x, y) is reflected along the x axis, its x coordinate remains the same and the y coordinate is opposite (negated). The new point is at (x, -y)

If a point (x, y) is translated h units to the right, the new coordinate is (x+h, y).The transformation are as follows:

It is reflected along the x axis so that the new coordinates would be at A1 at (- 4, -4), B1 at (- 2, -2), C1 at (- 2, 1), D1 at (- 4, -1)

It is translated 7 units to the right, The new coordinates are A' at (3, -4), B' at (5, -2), C' at (5, 1), D' at (3, -1)

Can i get brainliest plz, im trying to unpgrade my rank!

Alright, I am hoping this is an flvs question, and that it comes from the quiz.

I came to this question because I needed help on it, but now I understand it, so im gonna help others :)

For Part A, the answer would be reflected on the x axis, translated 7 units to the right. This is true because by only reflecting it, the figure would not be on the exact spot. We have to translate it to the right.

For part B, the simple answer is that they are NOT congruent. As shown, they have been translated and moved, so in conclusion, they are not congruent. PLS MARK BRAINLIEST, not trying to be mean or anything, but I need it way more than the other person if you look at our ranks.

The answer is 0.7 because 7/10 is the same thing as 0.7

Answer:

0.075, 75%, 3/4

Step-by-step explanation:

Convert everything to decimals for ease of comparison.

0.075 ⇒ Leave as is.

75% ⇒ Divide by 100 to make it a decimal number.

= [tex]\frac{75}{100}[/tex]

= 0.75

3/4 ⇒ Divide the numerator by the denominator.

= 0.75

Put them in order of place value:

Units  tenths   hundredths  thousandths

0.          0                7                    5

0.          7                5

0.          7                5

By comparing the numbers, we can put them in the following order from least to greatest:

0.075, 75%, 3/4

Answer: h(x)=2x-6

hope this helped

The  value of h(x)= 2x- 36.

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

f(x)=1/2x-3

Now, subtract 6 from the input of f to create a new function​ g

g(x)= 1/2x-3 -6

g(x)= 1/2x -9

and, multiply the input of function g by 4

h(x)= 4( 1/2x -9)

h(x) = 2x- 36

Hence, the value of h(x)= 2x- 36.
