What is the equation for the line of reflection? On a coordinate plane, triangle A B C has points (6, 3.7), (5.4, 2), (1, 3). Triangle A prime B prime C prime has points (3.7, 6), (2, 5.4), (3, 1). x = 3 y = 3 y = x x = 6

Step-by-step explanation:

We have,

[tex]\dfrac{20}{31}[/tex]

Show that [tex]\dfrac{20}{31}[/tex] is closer 66 % or 75 %.

∴ The percentage of [tex]\dfrac{20}{31}[/tex]

= [tex]\dfrac{20}{31}\times 100[/tex]

= [tex]\dfrac{2000}{31}[/tex]

= 64.516 %

≈ 66 %, shown.

Because the percentage of [tex]\dfrac{20}{31}[/tex] is 66 percent (%).

Thus, [tex]\dfrac{20}{31}[/tex] is closer 66 percent (%) , shown.

The fraction 20/31 is closer to 66%.

To determine which percentage 20/31 is closer to, we first need to convert the percentages into fractions and then compare them with 20/31.

66% can be written as a fraction as 66/100. Simplifying this fraction, we divide both the numerator and the denominator by their greatest common divisor, which is 2 in this case:

[tex]\[ \frac{66}{100} = \frac{66 \div 2}{100 \div 2} = \frac{33}{50} \][/tex]

Further simplifying by dividing both by 11, we get:

[tex]\[ \frac{33}{50} = \frac{33 \div 11}{50 \div 11} = \frac{3}{5} \][/tex]

75% as a fraction is 75/100. Simplifying this fraction by dividing both the numerator and the denominator by 25, we get:

[tex]\[ \frac{75}{100} = \frac{75 \div 25}{100 \div 25} = \frac{3}{4} \][/tex]

Now we compare the fraction 20/31 with 3/5 and 3/4. To compare these fractions, we can find a common denominator or convert them to decimal form.

Converting to decimal form:

[tex]\[ \frac{20}{31} \approx 0.645 \] \[ \frac{3}{5} = 0.6 \] \[ \frac{3}{4} = 0.75 \][/tex]

Now we can see that 0.645 is closer to 0.6 than it is to 0.75. Therefore, 20/31 is closer to 66% (or 3/5) than it is to 75% (or 3/4).

Alternatively, we could also cross-multiply to compare the fractions directly:

For 20/31 and 3/5:

[tex]\[ 20 \times 5 = 100 \] \[ 31 \times 3 = 93 \][/tex]

Since 100 is greater than 93, 20/31 is greater than 3/5, but not by much.

For 20/31 and 3/4:

[tex]\[ 20 \times 4 = 80 \] \[ 31 \times 3 = 93 \][/tex]

Since 93 is much greater than 80, 20/31 is less than 3/4 by a larger margin than its difference with 3/5.

Thus, by both methods, we conclude that 20/31 is closer to 66%.

Answer:

a = 2 ; b = 12

Step-by-step explanation:

p(x)=x⁴ + ax³ - 7x² - 8x +b

p(x) is exactly divisible by (x + 2). So p(-2)=0

(-2)⁴ + a(-2)³ - 7(-2)² - 8(-2) +b = 0

16 - 8a - 7*4 +16 + b =0

16 - 8a - 28 + 16 + b =0

4 - 8a + b = 0

-8a +  b = -4 -----------(i)

p(x) is exactly divisible by (x + 3). So p(-3)=0

(-3)⁴ + a(-3)³ - 7(-3)² - 8(-3) +b = 0

81 -27a - 63 + 24 + b =0

42 - 27a + b = 0

-27a + b = -42 ------------(ii)

                    -8a +  b = -4 -----------(i)

                    -27a + b = -42 ------------(ii)

subtract            19a = 38

                           a = 38/19 = 2

a=2

Substitute a value in equation (i)

-8*2 + b= -4

-16 + b = -4

       b = -4 + 16

       b = 12

Answer:

12 U.S teaspoons are in 1/4 cups.

The Formula is to multiply the volume value by 48.

So Since a 1/4 us cup=0.25 we can multiply this by 48.

0.25*48=12

So our awnser is 12 teaspoons

There are 12 teaspoons in 1/4 cups.

To understand this conversion, we need to know the standard conversion factors for cups and teaspoons. There are 16 teaspoons in 1 cup. Therefore, to find out how many teaspoons are in 1/4 cup, we divide the number of teaspoons in a full cup by 4.

Here is the calculation:

1 cup = 48 teaspoons

[tex]\( \frac{1}{4} \times 48 \)[/tex] teaspoons

[tex]\( = \frac{1}{4} \times \frac{48}{1} \)[/tex]

Answer:

Charges per flower delivered by Tina is, y= 2.99 (x) + 5

Step-by-step explanation:

Given:

Tina's charges per flower = 2.99 cents

Delivery charged by Tina = 5 units or 5$

We have fill the blank in terms of 'y'.

We know slope intercept form that is : y = m(x)+b

So here we have to fill numbers according to the slope intercept form.

Let the numbers of flowers sold by Tina be 'x'.

Here slope (m) will be the charge of each flower charged by the florist.

The delivery charge is the fixed rate so its the constant value and will be treated equivalent to y-intercept or b values.

Arranging our values:

[tex]m=2.99[/tex] cents , [tex]b=5\$[/tex]

Then the slope-intercept form :

⇒ [tex]y=m(x)+b[/tex]

⇒ [tex]y= 2.99(x) + 5[/tex]

We have to type only that goes in the blank and that is 2.99(x) +5.

y = 2.99(x) + 5 is our final answer.

Step-by-step explanation:

A new car is purchased for $17900. the value of the car depreciates at 12.25% per year.

Since the value of the car depreciates therefore the amount of the car is

[tex]A= P(1-\frac{r}{100})^n}[/tex]

    [tex]=17900(1-\frac{12.25}{100})^{10}[/tex]                [  p = $17900, r = 12.25% and n =10 years]

    = $ 4,845.34

Therefore the value of the car after 10 year will be = $4,845.34

The value of the car be, after 10 years will be $4845.34.

Given that,

A new car is purchased for 17900 dollars.

The value of the car depreciates at 12.25% per year.

We have to determine,

What will the value of the car be, after 10 years.

According to the question,

The value of the car depreciates therefore the amount of the car is determined by the formula,

[tex]A = P (1 -\dfrac{r}{100})^n[/tex]

Where, P = $17900, r = 12.25% and n =10 years

Substitute all the values in the formula,

[tex]A = P (1 -\frac{r}{100})^n\\\\A = 17900(1 -\frac{12.25}{100})^{10}\\\\A = 17900( 1- 0.1225)^{10}\\\\A = 17900(0.8775)^{10}\\\\A = 17900 \times 0.270\\\\A = 4845.34[/tex]

Hence, The value of the car be, after 10 years will be $4845.34.
