Answer:

Ann has 24 $1 bills, 2 $10 bills, and 8 $20 bills.

Step-by-step explanation:

Given that Ann has $1, $10, and $20 bills, and she has 4 times as many $20 bills as $10 bills and 3 times as many $1 bills as $20 bills, taking a total of $204, to determine the number of $1, $10, and $20 bills she has, she needs to perform the following calculation:

1 = 3x20 = 3x4x10 = 12x10

20 = 4x10

10 = 10

(12 x 1) + (4 x 20) + 10 = 12 + 80 + 10 = 102

(24 x 1) + (8 x 20) + (2 x 10) = 24 + 160 + 20 = 204

So Ann has 24 $1 bills, 2 $10 bills, and 8 $20 bills.

The segment BD is secant in the circle. Then the correct answer is option D.

A secant line is a straight line that passes through two points on a circle. The section of the line that connects two separate circle points is known as a chord. A chord is in a unique secant line and every secant line defines a unique chord.

Here we can see in the circle segment BD is passing at two points from the circle. Then BD is the secant of the circle.

Hence, the correct answer is option D.

Answer:

d₂ = 15 cm

Step-by-step explanation:

The area (A) of a kite is calculated as

A = [tex]\frac{1}{2}[/tex] d₁d₂

Here A = 120, d₁ = 16 , then

[tex]\frac{1}{2}[/tex] × 16 × d₂ = 120

8d₂ = 120 ( divide both sides by 8 )

d₂ = 15 cm

Answer:

The answer should be [tex]\frac{87}{50}[/tex]

Step-by-step explanation:

1.74 = [tex]\frac{174}{100}[/tex] = [tex]\frac{87}{50}[/tex]

Answer:

174% = 87/50 = 1 37/50 as a fraction

Step-by-step explanation:

174% = 174/100

Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(174,100) = 2. So,

(174÷2)/(100÷2) = 87/50 when reduced to the simplest form.

As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 174/100 is also equal to 1 37/50 when expressed as a mixed number.

Answer:

14 days

Step-by-step explanation:

you divide the total distance, 35, by the amount of miles ran per day, 2.5, to get 35/2.5=14.

The width and length of the chicken coop are 5.5 feet and 9.5 feet respectively.

The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.

The perimeter of a rectangle is given by P = 2L + 2W, where L is the length, W is the width and P is the perimeter.

We know that the width is w feet and the length is w+4 feet.

Given that the perimeter of the chicken coop is 30 feet, we can set up the following equation:

30 = 2(w + 4) + 2w

We can simplify this equation by combining like terms:

30 = 2w + 8 + 2w

30 = 4w + 8

22 = 4w

w = 5.5

So the width of the coop is 5.5 feet.

To find the length of the coop, we can use the information that the width is 5.5 feet and the length is w+4 feet.

The length of the coop is 5.5 + 4 = 9.5 feet

Answer:

y=-2x-6

Step-by-step explanation:

Slope intercept form of a line: y=mx+b (m is the slope and b is the y-intercept)

Convert our given line 6x+3y=4 into slope-intercept form to find the slope

Subtract 6x on both sides

3y=-6x+4

Divide 3 on both sides

y=-2x+4/3

The slope of the given line is the coefficient of x, -2

Parallel lines have the same slope, so the equation we're solving for also has a slope of -2

We also know that the y-intercept is -6, so we now have all the info we need to make the equation:

y=-2x-6

Answer:

42,-42

Step-by-step explanation:

We first solve for x from x^6 = 64, by taking the root of both sides, and we get x = 2,-2

We then plug in both of the x values and get 42,-42

PS: That should be the right answer but you didn't include the possible answers, and I somehow also got 30 when plugging in -2, but just try it yourself to be safe.

answer:

step-by-step explanation:

hello there!

as you said, there is only able one output ( y ) for each input ( x ) for it able to become a function

here is a little example of a "table" to help me explain this a little better for you!

input ( x ) | output ( y)

      8       |       -3

      3       |       8

      9       |       4

     -2       |       2

since none the inputs have more then one output then that means it is a function

Let us first resolve the given numbers into prime factors.

By prime factorization,

[tex] \longmapsto [/tex] √8 = √( 2 × 2 × 2)

[tex] \longmapsto [/tex] √8 = 2√2

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

[tex] \longmapsto [/tex] √98 = √( 2 × 7 × 7)

[tex] \longmapsto [/tex] √98 = 7√2

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

[tex] \longmapsto [/tex] √32 = √( 2 × 2 × 2 × 2 × 2)

[tex] \longmapsto [/tex] √32 = 2 × 2√2

[tex] \longmapsto [/tex] √32 = 4√2

According to the question,

[tex] \longmapsto [/tex] √8+√98+√32

[tex] \longmapsto [/tex] 2√2 + 7√2 + 4√2

[tex] \longmapsto [/tex] √2(2 + 7 + 4)

[tex] \longmapsto [/tex] √2(13)

[tex] \longmapsto [/tex] 13√2

So, we get that :
