Find m< AEB. Please help

Answer:

71.13

Step-by-step explanation:

The half area of a circle is A = 1/2 * pi*r^2 = 1/2 * pi * 3^2 or 9

The trapezoid is a rectangle and a triangle. Rectangle is 8*6 and the triangle is 6*(11 - 8) * 1/2

The total is 1/2 * pi * 9 + 8*6 + 6*(11 - 8) * 1/2 = 71.13

Answer:

B

Step-by-step explanation:

-5(2x-4y)

-5*2x = -10y

-5*-4y = 20y

So, -10x+20y

Answer:

$8

Step-by-step explanation:

first you have to find one

0.5 ounce = $2.40 ÷ 3 = $0.80

1 ounce = 0.8 × 2 = $1.60

5 ounces $1.60 × 5 = $8

Answer:

The answer is b

Step-by-step explanation:

Answer:

$19

Step-by-step explanation:

first subtract 3 from 51 and that =48

then divide 48 between the 3 people and that equals 16

lastly add Kadens tip of 3$ which will equal $19.

Answer:

The answer above is wrong, the line is actually supposed to be one to the left, so it would be going through (7,4) and (2,-2)

Step-by-step explanation:

Answer:

{-5/4, 8}

Step-by-step explanation:

We are given (4u + 5)(8 - u) = 0.  Solve for u by setting each of the factors (4u + 5) and (8 - u) equal to zero and solving each of the resulting equations:

4u + 5 = 0 leads to u = -5/4, and

8 - u = 0 leads to u = 8.

The solutions are {-5/4, 8}

Answer:6 17/18 hours

Step-by-step explanation:

We are informed that on Monday Katie spent 2 1/6 hours studying while onn Tuesday she spent another 4 7/9 hours studying.

The combined length of time she spent studying will be the addition of the numbers of hours spent studying on Monday and Tuesday. This will be:

= 2 1/6 + 4 7/9

= 2 3/18 + 4 14/18

= 6 17/18

She used a total of 6 17/18 hours studying

Answer:

50º

Step-by-step explanation:

A triangles angles = 180º

Angle A = 40º

Angle C = 90º  (this is a right triangle)

40º + 90º = 130º

180º - 130 º = 50º

Answer: two times

Step-by-step explanation:

Given

height of cone A and B  [tex]h_a=h_b=5\ in.[/tex]

The volume of cone A  [tex]V_a=20.9\ in.^3[/tex]

The volume of cone B is 4 times of cone A

the volume of a cone is  [tex]\frac{1}{3}\pi r^2h[/tex]

The volume of cone A

[tex]V_a=\dfrac{1}{3}\pi r_a^2h_a=20.9\quad \ldots(i)[/tex]

The volume of cone B

[tex]V_b=\dfrac{1}{3}\pi r_b^2h_b=4\times 20.9\quad \ldots(ii)[/tex]

divide (i) and (ii) we get

[tex]\Rightarrow \dfrac{r_a^2}{r_b^2}=\dfrac{1}{4}\\\Rightarrow \dfrac{r_a}{r_b}=\sqrt{\dfrac{1}{4}}=\dfrac{1}{2}\\\Rightarrow \dfrac{d_a}{d_b}=\dfrac{1}{2}\\\Rightarrow d_b=2d_a[/tex]

thus, diameter of cone B is twice the diameter of A

This diagram is not really to scale much but that would be the math you'd use to find angle m

Answer:

y= -7

Step-by-step explanation:

There's no need to include x as the y-value will always be -7, but if your question requires it then you could say something like y=(x-x)-7

Answer:

The answer is 1. f(a) = –2a^2 – 5a + 4. If a = -3, then to find f(-3) we have to substitute a in the general formula. f(a) = –2a^2 – 5a + 4 = -2 * a^2 – 5 * a + 4. Substitute a with -3. f(-3) = –2 * (-3)^2 – 5 * (-3) + 4 = -2 * 9 - (-15) + 4 = -18 + 15 + 4 = 1

Answer:

80

Step-by-step explanation:

48:60*100 =

(48*100):60 =

4800:60 = 80

Answer:

48 is 80 percent of 60

Answer:

x = 10, y = 12

Step-by-step explanation:

There is a 2:1 ratio between 16 and 8, alternate side lengths.

2x = 20

x = 10

2(6) = y

y = 12

Answer:

x=27

Step-by-step explanation:

cos and sin are complementary angles. There theta or x add up to 90 degree. Using the formula.

cos x=sin y where x+y=90 let set up the equation.

[tex] \cos(2x + 9) = \sin(x) [/tex]

[tex]2x + 9 + x = 90[/tex]

[tex]3x + 9 = 90[/tex]

[tex]3x = 81[/tex]

[tex]x = 27[/tex]

To check our identity plug x in the top equation

[tex] \cos(2 \times 27 + 9)) = \sin(27) [/tex]

[tex] \cos(63) = \sin(27) [/tex]

they both equal about 0.45 so it is true.

x=27

Answer:

C

Step-by-step explanation:

Let's try it

Take 4 out of the given function.

4(x^2 + 3x )

Now there is an ex on either side of the plus sign that can come out. If 4 can come out because a 4 is on either side of the plus sign, so can an ex.

4x(x + 3)

What have you found?

4 is a factor

x is a factor

x + 3 is a factor

What about 3x. Well it won't work evenly and a factor must divide evenly into the given function.

Answer:

B 17.5 ft

Step-by-step explanation:

tangent = opposite / adjacent

tan 35° = h / 25

multiply both sides by 25

h = 25 (tan 35°)

tan 35° = 0.70 (from your calculator)

h = 25 (0.70)

h = 17.51 ft.

Answer: 12.57 ft

Step-by-step explanation:

Circumference of circle with radius of 4ft.

= π * radius * 2

= 22/7 * 4 * 2

= 25.14 ft

Circumference of circle with radius of 6ft.

= 22/7 * 6 * 2

= 37.71 ft

Difference = 37.71 - 25.14

= 12.57 ft
