Answer:

8 (a=8)

Step-by-step explanation:

40-32 = 8

Answer:

Diameter14

Using the formulas

A=πr2

d=2r

Solving for A

A=1

4πd2=1

Answer:

[tex]Height = 7in[/tex]

Step-by-step explanation:

Given

See attachment for parallelogram

[tex]Base = 28in[/tex]

Required

What is the height?

The opposite sides of a parallelogram are equal and the height is the distance between the parallel sides.

From the question, we have:

[tex]Base = 28in[/tex]

Also from the question, the difference between the two parallel sides is 7in.

Hence, the height of the parallelogram in 7in

Answer:

Step-by-step explanation:

-2÷1 = -2

4÷(-2) = -2

-8:4 = -2

So this is a geometric sequence with a common ratio of -2

Therefore:

the 5th term:   -8×(-2) = 16

the 6th term:   16×(-2) = -32

Answer:

114

Step-by-step explanation:

since the total degrees of ANY triangle is 180 degrees, you just simply do 180-38-28 and you would get 114!

Answer:78.5

Step-by-step explanation:

the median is the middle digit so with 10 different numbers it would be the 5th or sixth number  

but you have to first have them in least to greatest order

53,59,68,70,75,82,82,87,94,95

5th+6th/2

75+82= 157

157/2

Answer:

x - 9y

Step-by-step explanation:

-2x + 3x = x

-4y - 5y = -9y

Have a good day :)

Answer:

x = 9

Step-by-step explanation:

5x+4 = 49

subtract 4 from both sides

5x = 45

divide both sides by 5

x = 9

Answer:

x = 9

Step-by-step explanation:

49 degrees and (5x + 4) are vertical lines, meaning they are congruent.

We can make an equation with this information:

(5x + 4) = 49

      -4      -4

5x = 45

/5     /5

x = 9

Answer:

11.28 units squared

Step-by-step explanation:

Area of a circle is

[tex]\pi {r}^{2} [/tex]

each square has an area of 1

There are four semi-circles, which make two complete circles.

the area of the 5 squares plus the area of the two circles equals the total area.

5 + 2(3.14) = 11.28

Answer:

B zyx

Step-by-step explanation:

major arc is more than half the circle. this is the only one which is less than half the circle.

Answer:

Well..They gave you the hint all you have to do is apply the formula

hint: the way a quadratic formula is written is [tex]ax^2 + bx + c[/tex]

So lets do this

axis of symmetry = [tex]\frac{-b}{2a} = \frac{-(-12)}{2(-3)} = \frac{12}{-6} = -2 = x[/tex]

Answer:

26x+25

Step-by-step explanation:

not sure if this an answer choice but here

Let's simplify step-by-step.

19x+18+7+4x+3x

Combine Like Terms:

=19x+18+7+4x+3x

=(19x+4x+3x)+(18+7)

=26x+25

Answer:

=26x+25

Answer:

[tex]P(x > 1\ and\ x < 2) = \frac{4}{25}[/tex]

Step-by-step explanation:

Given

[tex]S = \{1,2,3,4,5\}[/tex]

[tex]n(S) = 5[/tex]

Required

[tex]P(x > 1\ and\ x < 2)[/tex]

[tex]P(x > 1\ and\ x < 2)[/tex] is calculated as:

[tex]P(x > 1\ and\ x < 2) = P(x > 1) * P(x < 2)[/tex]

Since it is a probability with replacement, we have:

[tex]P(x > 1\ and\ x < 2) = \frac{n(x > 1)}{n(S)} * \frac{n(x < 2)}{n(S)}[/tex]

For x > 1, we have:

[tex]x > 1 = \{2,3,4,5\}\\[/tex]

[tex]n(x > 1) = 4[/tex]

For x < 2, we have:

[tex]x < 2 = \{1\}[/tex]

[tex]n(x < 2) = 1[/tex]

[tex]P(x > 1\ and\ x < 2) = \frac{n(x > 1)}{n(S)} * \frac{n(x < 2)}{n(S)}[/tex]

becomes

[tex]P(x > 1\ and\ x < 2) = \frac{4}{5} * \frac{1}{5}[/tex]

[tex]P(x > 1\ and\ x < 2) = \frac{4}{25}[/tex]

Answer:

12.5

Step-by-step explanation:

put them in order from least to greatest: 11, 11, 12, 12, 12, 13, 13, 14, 15, 16

the middle is 12 and 13 so you do 12+13 then divide by 2

to get 12.5

hope this helps

Answer:

It is decay  because the value of the car keeps falling.

for example, the value next year, would be 12250 x (100% - 11%) = $10,902.50

If it were a growth, the value would increase yearly

12250 x (0.89)^time

Step-by-step explanation:

the equation to represent exponential decay = Amount x ( 1 - rate)^time

Answer:

area = 82 cm²

Step-by-step explanation:

The figure comprises a trapezoid, a triangle and a square.

Calculating areas of the three shapes separately and then adding them will give us the required area of the composite figure.

Area of square : (side)²

= (2)²

= 4 cm²

Area of triangle : ½ × b × h

= ½ × 3 × 12

= 3 × 6

= 18 cm²

Area of trapezoid : ½ × (a + b) × h

= ½ × (5+5) × 12

= ½ × 10 × 12

= 5 × 12

= 60 cm²

Now, area of the composite figure :

= 4 + 18 + 60

= 22 + 60

= 82 cm²

Answer:

Step-by-step explanation:

If you exclude the square on the bottom, you have a trapezoid with bases of 5 cm and 8 cm and the height of 12 cm.

Its area is:

Add the area of the square with sides of 2 cm:

Total area is:

Step-by-step explanation:

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find the time that the rocket will hit the ground, to the nearest 100th of second.

y=-16x^2+129x+119
