Sean is determining the number of quarters equal to different dollar amounts.
There is a proportional relationship between the amount of money in dollars, x, and the number of quarters, y.

Answer:

A.

[tex] SA= \frac{2}{3} \pi rl+16 \pi r^2[/tex]

Step-by-step explanation:

Surface area of the original cone

[tex] SA= \pi r l + \pi r^2... (1)[/tex]

When, radius is quadrupled and slant height is reduced to one sixth

[tex] i. e. \: \:r = 4r\: \: \&\:\: l= \frac{1}{6}l[/tex]

Plug the above values of r and [tex] l[/tex] in equation (1), new surface area becomes:

[tex] SA= \pi (4r)\times \frac{1}{6} l+ \pi (4r)^2[/tex]

[tex] SA= \frac{4}{6} \pi rl+16 \pi r^2[/tex]

[tex]\huge \purple {\boxed {SA= \frac{2}{3} \pi rl+16 \pi r^2}} [/tex]

Answer:

y = -3x - 3

Step-by-step explanation:

y = -3x + b

0 = -3(-1) + b

0 = 3 + b

-3 = b

y = -3x - 3

Answer:

down there with the work :)

Step-by-step explanation:

formula: a^2+b^2=c^2

Page 1:

1)

6^2+8^2=c^2

36+64=c^2

100=c^2

take the square root of both sides

c=10

2)

8^2+b^2=12^2

64+b^2=144

80=b^2

b=[tex]4\sqrt{5}[/tex]

3)

14^2+b^2=48^2

196+b^2=2304

b^2=2108

b=[tex]2\sqrt{527}[/tex]

Page 2:

1)

5^2+11^2=13^2

25+121=169

no this is not true so this is not a right triangle

2)

10^2+24^2=26^2

100+576=676

this is true so this IS a right triangle

hope this helps!

Answer: Option B

Step-by-step explanation:

Answer:

10

Step-by-step explanation:

distance formula = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}

(x_1, y_1) = (5, 1)

(x_2, y_2) = (-3, -5)

\sqrt{ [(-3) - (5)]^2 + [(-5) - (1)]^2 }

\sqrt{ [-8]^2 + [-6]^2 }

\sqrt{ 64 + 36 }

\sqrt{ 100 }

= 10

Answer:

[tex] Distance = 10 \ u [/tex]

Step-by-step explanation:

Given :-

And we need to find the distance between the two points . We can use distance formula here to find the distance between the two points . The distance formula for two points ,

Distance Formula :-

[tex]\implies Distance =\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex]\implies Distance =\sqrt{\{5-(-3)\}^2+\{1-(-5)\}^2 } \\\\\implies Distance =\sqrt{ (5+3)^2+(1+5)^2}\\\\\implies Distance =\sqrt{ 8^2+6^2}\\\\\implies Distance =\sqrt{64+36}\\\\\implies Distance =\sqrt{100}\\\\\implies Distance = 10\ units [/tex]

Hence the distance between the two points is 10 units .

Answer:

Cost of cell phone in U.S. dollar = 100 U.S. dollar

Step-by-step explanation:

Given:

Cost of cell phone in yen = 8,835.3 yen

1 U.S. dollar = 88.353 yen

Find:

Cost of cell phone in U.S. dollar

Computation:

Cost of cell phone in U.S. dollar = Cost of cell phone in yen[1 /  88.353]

Cost of cell phone in U.S. dollar = 8,835.3[1 /  88.353]

Cost of cell phone in U.S. dollar = 8,835.3 /  88.353

Cost of cell phone in U.S. dollar = 100 U.S. dollar

Answer:

B) The value of r would not change

Step-by-step explanation:

If there's a positive association between sodium and calories, that's like saying there's a positive association between calories and sodium. Therefore, the value of r would not change because both variables are still increasing with each other.

Answer:

x = 7, x = 5

Step-by-step explanation:

Given 2 intersecting chords, then

The product of the parts of one chord is equal to the product of the parts of the other chord.

(1)

27x = 9 × 21 = 189 ( divide both sides by 27 )

x = 7

(2)

12(3x - 5) = 120 ( divide both sides by 12 )

3x - 5 = 10 ( add 5 to both sides )

3x = 15 ( divide both sides by 3 )

x = 5

Answer:

2x+12

Step-by-step explanation:

2x+3(x−2)−3(x−6)

Distribute:

=2x+(3)(x)+(3)(−2)+(−3)(x)+(−3)(−6)

=2x+3x+−6+−3x+18

Combine Like Terms:

=2x+3x+−6+−3x+18

=(2x+3x+−3x)+(−6+18)

=2x+12

Answer:

=2x+12

Answer:

2x + 12

Step-by-step explanation:

distribute numbers inside parentheses

2x + 3x -6 -3x + 18

add x values together and integers together

2x + 3x -3x = 2x

-6 + 18 = 10

simplified to 2x + 12

Answer:

27.83 dollars

Step-by-step explanation:

Answer:

y = 312x + 2

Step-by-step explanation:

According to y = mx + b, m stands for slope and b stands for y-intercept. Let us find the y-intercept. To find the y-intercept, the x should be zero in (x, y).

(x, y)

(0, 2) ---> y-intercept (b)

Now that we have found the y-intercept, we will now find the slope by using its formula.

Slope formula:-

m = y2 - y1 / x2 - x1

Pick two random (x, y). I will pick the first and last pairs.

(0, 2) and (4, 1250)

Now plug these two pairs in the formula.

m = y2 - y1 / x2 - x1

m = 1250 - 2 / 4 - 0

m = 1248 / 4

m = 312

This means that the slope (m) is 312. Now put that in y = mx + b form.

y = mx + b

y = 312x + 2

Both of the forms are the same. Hope this helps, thank you :) !!
