Which of these sets is a Pythagoreah Triple?
A) 5, 8, 17
B) 21, 20, 41
C) 4,5,6
D) 64, 36, 100

Answer:

8.88

Step-by-step explanation:

I believe it is 8.88 becuase this question is asking to find 90% pf that number.  

What do you need to do?

you have to make a proportion.

8/x 90/ 100

You would now cross multiply. 90* x = 90x 8*100= 800

the equation you would need is 90x = 800. divide them and you get 8.88.

ROUNDED: you get 9.

I believe this is correct sorry if it was incorrect.

Answer:

C. {(1,H), (2,H), (3,H), (4,H), (1,T), (2,T), (3,T), (4,T)}

Answer:

  28 square units

Step-by-step explanation:

The figure can be decomposed several ways. Maybe easiest to see is as a 8×4 rectangle with a 2×4 right triangle cut from the corner.

The area of the rectangle is ...

  A = LW = (8)(4) = 32

The area of the missing triangle is ...

  A = 1/2bh = 1/2(2)(4) = 4

Then the area of the shaded figure is ...

  32 - 4 = 28 . . . square units

_____

Alternate solution

If you divide the figure with a horizontal line across the middle, it becomes a 4×4 square and a trapezoid with bases 2 and 4 and height 4. The shaded area is the sum of these areas.

The area of a trapezoid is ...

  A = 1/2(b1 +b2)h

  A = (1/2)(2 +4)(4) = 12

The area of the square is ...

  A = s² = 4² = 16

Then the total area is ...

  12 +16 = 28 . . . square units

Answer:

R=? D=? C=\pi[/tex]

Step-by-step explanation:

R is a radius, the radius is a line segment from the center of a circle.

D is a distance around. Another word for D is the perimeter.

Pi is a circle's circumference (Which never ends.)

For example: 3.1415926535 8979323846 2643383279 5028841971 6939937510 5820974944 5923078164 0628620899 8628034825 3421170679...

And the pi is 31,415,926,535,897.

Pi meaning is a half-radius x half-radius x circumference.

Answer:

8: 73.2 cm

10: 738 mm

Step-by-step explanation:

8: A= 12.2 (4.5 + 7.5) / 2 --> 146.2 / 2 = 73.2 cm

10: A= 36 (22 + 19) / 2 --> 1,476 / 2 = 738 mm

Answer:

8: 73.2

10: 738

Step-by-step explanation:

Area of a trapezoid = [tex]A=\frac{a+b}{2} h[/tex]

where a and b = base lengths and h = height

For #8

These are the given dimensions

Base 1 = 4.5

Base 2 = 7.5

Height = 12.2

All we have to do is plug in the values into the formula

So....

[tex]A=\frac{4.5+7.5}{2} 12.2\\4.5+7.5=12\\\frac{12}{2} =6\\6*12.2=73.2[/tex]

Hence the answer is 73.2cm²

For #10

Once again all we have to do is plug in the values into the formula

[tex]A=\frac{22+19}{2} 36\\22+19=41\\\frac{41}{2} =20.5\\20.5*36=738[/tex]

Hence the answer is 738

Answer: The probability of drawing a heart out of the deck is 13/52, or 1/4. The probability of drawing an even number as card #2 (c∈{2,4,6,8,10}) for any suit is 20/51, except when the first card drawn is an even heart, then the probability of the second draw is 19/51.

Answer:

7/2 feet

Step-by-step explanation:

Volume of Right Rectangular Prism: V = w * h * l

You are given the volume, and the base (which would include l and w)- and are told to find h.

70 7/8 cubic feet = 4 1/2 feet * h * 4 1/2 feet (simplify the right side)

70 7/8 cubic feet = 81/4 feet squared * h (divide both sides by 81/4)

7/2 feet = h

The height will be 7/2

2 blank. is 18

3blank. 6/7

4 blank. 1

Step-by-step explanation:

   it wants you to reorganize things by like terms

   So the first blank should be your other t value

   so 5/7t

   The second blank would be your number with no x

   so 18

   and your last two blanks are the simplification

   so 6/7

   and then 1

Answer:

Jasraj walked 4 kilometers all together

Step-by-step explanation:

First, add.

1,500 + 500 = 2,000

Then, multiply by 2.

2,000 × 2 = 4,000

Now, we have to convert to kilometers.

1 kilometer = 1000 meters

4,000 ÷ 1,000 = 4

So, Jasraj walked 4 kilometers!

Have a wondeful day! :)
