how to find the area of a circle with radius

Answer:

The first one is a square! The second is none of these because its a trapezoid

Step-by-step explanation:

Answer:

7. all of the above

9. none of these

Step-by-step explanation:

graph number 7

you will see from the diagonal test that the diagonals of this shape are congruent. All four angles in the interior are congruent making it a rhombus. The outside side lengths are all equal to 6.71. Making it a rectangle. The definition of a square is if it is both a rectangle and a rhombus then it is a square.

graph number 9

you can plainly see that this is a trapazoid which is none of either of these choices.

hope this helps.

Angle E and D are supplementary and need to equal 170 when added together.

Angle D = 180-35 = 145

Angle D is split into two with part of it being 44

The missing angle is 145-44 = 101 degrees

The answer is 101

Answer:

x= 4, y = -1

Step-by-step explanation:

2x-3y=11

3x+3y=9

do addition and you should get

5x=20

x=4

plug in x into any equation

12+3y=9

3y= -3

y=-1

Answer:

A = 64 pi

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

The radius is 8

A = pi * 8^2

A = 64 pi

Answer:

s = the number of student tickets sold a = the number of adult tickets sold The drama class sold 25 more student tickets than adult tickets to the fall play s = a + 25 The class collected $660 from ticket sales: 6s + 3a = 660 divide both sides by 3 2s + a = 220 by solving the system of equations s = a + 25 2s + a = 220 we find s = 81.67 student tickets a = 56.67 adult tickets

Step-by-step explanation: 2.325 + 27.9 + 15.50

Answer:

p = 4n

p = 312 passengers

n = 19.5 cars

Step-by-step explanation:

Let

n = number of cars

p = number of passengers

a. p = 4n

b. p = 4n

Find p if n = 78

p = 4n

p = 4 * 78

p = 312 passengers

c. Find n if p = 78

p = 4n

78 = 4n

Divide both sides by 4

78 / 4 = 4n / 4

19.5 = n

n = 19.5 cars

Step-by-step explanation:

Answer:

1.5x+12=26

Step-by-step explanation:

Andy currently runs a total of 12 miles per week. He plans to increase that number by 1.5 miles, so number of miles increased in x weeks will be 1.5x and total number of miles ran in x weeks will be 1.5x+12.

Since Andy wants to reach a total of 26 miles per week, so we will equate the total number of miles ran in x weeks with 26.

Answer:

5/12 x 2/3 = 10/36 = 5/18 foot2

Answer:

3/10

Step-by-step explanation:

y2 - y1 / x2 - x1

4 - 1 / 4 - (-6)

3/ 10

Answer:

Step-by-step explanation:

y1-y2

--------

x1-x2

so

and (x1,y1) and (x2,y2) are those points so plug it in

(1-4)/(-6-4) so that simplifies to -3/-10 so just 3/10 is the slope.

Answer:

15 + x(.5) = 24 ; x = 18

Step-by-step explanation:

15 + 18(.5) = 24

15 + 9 = 24

Step-by-step explanation:

t is the number of ride tickets she can buy.

=>

[tex]15 + t \times 0.5 \leqslant 24[/tex]

she has to pay $15 just for entering. the rest of the money she can use for ride tickets.

so, whatever she does, she has to stay inside the $24 limit, as she does not have more money.

the $15 admission goes off the $24 available money. that leaves $9.

each ride ticket costs $0.50, so she can buy max. 9/0.5 = 18 tickets. she can buy fewer tickets, but she cannot buy more than these 18 tickets.

so, again

[tex]15 + t \times 0.5 \leqslant 24[/tex]

[tex]t \times 0.5 \leqslant 24 - 15 = 9[/tex]

[tex]t \times 0.5 \leqslant 9[/tex]

[tex]t \leqslant 9 \div 0.5 = 9 \div (1 \div 2) = 2 \times 9 \div 1 \\ = 18[/tex]

[tex]t \leqslant 18[/tex]

Answer:

31,38,45

Step-by-step explanation:

Answer:

31, 38, & 45

Step-by-step explanation:

The sequence 10, 17, 24 increases by 7 each term.

10 + 7 = 17

17 + 7 = 24

24 + 7 = 31

31 + 7 = 38

38 + 7 = 45

Answer:

t  =  2.25 h

Step-by-step explanation:

In the case, I cover distance d in 3 hours

d =  3 * v₁      (1)

In the second case my speed increase by 1/3 then my speed is  

v₁ + (1/3) v₁   =  (3/3  + 1/3  ) *v₁

my new speed is   (4/3) * v₁  and

d  =  (4/3)*v₁ * t    (2)

Dividing (2) by  (1)  we get

1   = (4/3) *v₁*t/ 3*v₁

1  =  (4/9)*t

t = 9/4  h

t  =  2.25 h

Answer:

x = 9 degrees

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin theta = opp side/ hypotenuse

sin x = 15/91

Taking the inverse sin of each side

sin ^-1 (sin (x)) = sin ^ -1( 15/91)

x =9.487658996

To the nearest degree

x = 9 degrees

Answer:

297

Step-by-step explanation:

Since we have to make 9 as the whole, and 33 is the denominator to make 9, we need to multiply 9*33=297.

This makes no sense if you hear it. But trust me it is the right answer i think.

Answer:

D. (–2, –2); minimum

Step-by-step explanation:

It’s D you got to see the lowest part of the graph and you will call it mini except if the graph was going down you will call that point maximum.

Answer:

D. (-2, -2); minimum

Step-by-step explanation:

The vertex is the where the curve turns up/down which divides the figure into two halves.

From the given graph, the graph turns up at (-2, -2) , the graph moves down, therefore, the vertex (-2, -2); minimum.

Hope this will helpful.

Thank you.
