Answer:

Circle B has an area of 200.96 in².

Step-by-step explanation:

π = 3.14

radius of circle A = diameter of circle A/2

= 16 in/ 2 = 8 in.

Area = πr² = (3.14)(8²)

= (3.14)(64)

= 200.96 in²

Answer:

none

Step-by-step explanation:

Answer:

y = - [tex]\frac{1}{3}[/tex] x + 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - [tex]\frac{1}{3}[/tex] , then

y = - [tex]\frac{1}{3}[/tex] x + c ← is the partial equation

To find c substitute (6, 3 ) into the partial equation

3 = - 2 + c ⇒ c = 3 + 2 = 5

y = - [tex]\frac{1}{3}[/tex] x + 5 ← equation of line

Answer:

9.25≤x≤64.15

Step-by-step explanation:

The smallest amount would be 5 of the least priced item

5 * 1.85 =9.25

The largest amount would be 5 of the greatest priced item

5 * 12.83 =64.15

9.25≤x≤64.15

Use the area of rectangle formula which is:

[tex] \displaystyle \large \tt{A = width \times length}[/tex]

Given that:

Substitute in the formula:

[tex] \displaystyle \large{16 = 8 \times (x - 5)} \\ \displaystyle \large{16 = 8(x - 5)}[/tex]

Distribute 8 in the expression:

[tex] \displaystyle \large{16 = (8 \times x) + (8 \times ( - 5))} \\ \displaystyle \large{16 = 8x - 40}[/tex]

Move -40 to another side and change from -40 to 40.

[tex] \displaystyle \large{16 + 40 = 8x} \\ \displaystyle \large{56= 8x} \\ [/tex]

Then move 8 to divide 56, leaving only x.

[tex] \displaystyle \large{ \frac{56}{8} = x} \\ \displaystyle \large{7 = x} \\ [/tex]

Hence, the answer is:

[tex] \displaystyle \large \boxed{x = 7} \\ [/tex]

Answer:

By Pythagoras theorem ,

H^2 = P^2 + B^2

H^2 = 4^2 + 3^2

H^2 = 16 + 9

H^2 = 25

H = 5

therefore , value of x = 5

hope that helps uh..☺

Answer:

x = 5

Step-by-step explanation:

Since it's a right triangle, you can use Pythagorean Theorem.

[tex]a^2+b^2=c^2\\3^2+4^2=x^2\\9+16=x^2\\25=x^2\\5=x[/tex]

Step-by-step explanation:

Answer:

Step-by-step explanation:

a = 9 mm ;  b = 6 mm  ;  c = 12 mm

S = (a + b +c) / 2

  [tex]= \dfrac{9 + 6 + 12}{2}\\\\= \dfrac{27}{2}\\\\= 13.5 \ mm[/tex]

S - a = 13.5 - 9 = 4.5 mm

s -b = 13.5 - 6 = 7.5 mm

s -c = 13.5 - 12 = 1.5  mm

Area = [tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex]

       [tex]= \sqrt{13.5 * 4.5 * 7.5 * 1.5} \\\\= \sqrt{683.4375} \\\\=26.1 \ mm^{2}[/tex]

Answer:

m=15.78

Step-by-step explanation:

density = volume / mass

subtitute values:

95= 1500/ mass

mass = 1500/95

m= 15.78

Answer:

[tex]p=-6.25[/tex] or [tex]p=\displaystyle-\frac{25}{4}[/tex]

Step-by-step explanation:

[tex]-160=22+8(3p-4)[/tex]

Our goal here is to isolate p on one side of the equation. We will do this by performing inverse operations on both sides.

Subtract 22 from both sides:

[tex]-160-22=22+8(3p-4)-22\\-182=8(3p-4)[/tex]

Divide both sides by 8:

[tex]-22.75=3p-4[/tex]

Add 4 to both sides:

[tex]-22.75+4=3p-4+4\\-18.75=3p[/tex]

Divide both sides by 3:

[tex]-6.25=p[/tex]

You can also convert this into a fraction:

[tex]p=\displaystyle-\frac{25}{4}[/tex]

Answer:

63

Step-by-step explanation:

Area = large rectangle + small rectangle + triangle

A = (L1 * W1) + (L2 * W2) + 1/2 base * heigth)

A = (9 * 5) + (2 * 3) + 1/2(((2 + 5 + 2) - (3)) * 4))

A = 45 + 6 + 1/2((9 - 3) * 4)

A = 51 + 1/2(6 * 4)

A = 51 + 1/2(24) = 51 + 12 = 63

Answer:

1.5 miles.

Step-by-step explanation:

You can figure it out by dividing the yards by 1760.

Answer:

1.5 miles

Step-by-step explanation:

A mile is 1760 yards

2640 yds * 1 mil/1760 yds = 2640/1760 = 1.5 miles

Step-by-step explanation:

hope you understand I've shown the process in the picture.

Answer:

(a) x = 40°

Step-by-step explanation:

(2x+43)°+(2x-3)°=180°

4x+40°=180°

x=40°

Answer:

The Equation of the Line that Passes through the Points (2, −1) and (4, 5) is 3x - y - 7 = 0.

Answer:

x=15

Step-by-step explanation:

3(x-5)=30

First, you would distribute the three to the x and the negative five.

3x-15=30

Then you would add 15 to the 15 to cancel it and to the 30 to make it even.

3x-15=30

  +15=+15=

3x=45

Finally, you would divide 3 into both sides, cancelling out the three and fiving you,

x=15

Hope this helped!

Start by distributing the 3 through the parenthses on the left side.

This gives us 3x - 15 = 30.

Now add 15 to both sides to end up with 3x = 45.

Dividing both sides by 3, we fin that x = 15.

Answer:

z = 8/3

Step-by-step explanation:

10- 3/4z = 8

Subtract 10 from each side

10-10- 3/4z = 8-10

-3/4z = -2

Multiply each side by -4/3

-3/4z * -4/3 = -2 *4/3

z = 8/3
