Answer the following about estimating 342/6 .

Answer: D

Step-by-step explanation:

Answer:  803.84

Step-by-step explanation: pi * r^2 * height

Answer:

803.84

Step-by-step explanation:

because its pi x r² x height

in this case the radius is 4 because the diameter is 8 and half would be 4 so its 4² which is 16 and the height is 16 and you mulitply pi which is 3.14 so 16 x 16 x 3.14= 803.84cm

Answer:

16 units^2

Step-by-step explanation:

The surface area of a square pyramid is comprised of the area of its square base and the area of each of its four triangular faces. Given height h and edge length a, the surface area can be calculated

Answer:

Each triangle has an area of 6 and the square in the middle has an area of 9.

6 times 4 is 24, plus 9 is 33. Therefore, your surface area is 33

Answer:

1) 20 miles

2) 8cm

3)

Step-by-step explanation:

1) Each mile is 1/4 of an inch. and there are 5 inches.

    To figure out how many miles we do we need to figure out how many 1/4 of an inch is in 5 inches.

    First, we figure out that 4 of 1/4 of an inch = 4 miles because you have 4 parts = 4/4 which = 1.

    So we figured out that 1 inch = a mile.

    Then the rest is really easy. We add 4 together 5 times

    4 plus 4 plus 4 plus 4 plus 4 which = 20

    (Another way you could do it is to multiply 4 by 5)

     So the answer to #1 is 20 miles to walk to school.

2) 2cm (Centimeter) = 1 m (meter) and there are 4 meters in the car

    Basically, it is straightforward based on what I did on the first problem

    So you add 2 + 2 + 2 + 2 to get 8m

    Or you multiply 2 by 4 to get 8m

    So if the car is 4m the length is 8cm

3) sorry to busy to do number 3, i hope you figure it out.

Answer:

C. [tex]\sqrt{89}[/tex] cm

Step-by-step explanation:

First, we can start out by stating that this is a right triangle, since it has a right angle, shown by the marker square in the corner of the triangle. The x part, is called the hypotenuse. When finding the value of the hypotenuse, we use a thing called the Pythagorean Theorem. This theorem is :

a^2 + b^2 = c^2

a is one side length, and b is the other. c is the hypotenuse. To find x, the hypotenuse, we simply plug in the values, and solve.

8^2 + 5^2 = c^2

64 + 25 = c^2

89 = c^2

To get c alone, we do the square root of 89.

[tex]\sqrt{89}[/tex] = c

9.43398113 = c

So, the answer is C. [tex]\sqrt{89}[/tex] cm

Answer:

25.92

Step-by-step explanation:

The formula for the volume of a triangular prism is 1/2(b*h*l).  So, it would be 3.6 * 2.4 * 6 = 51.84. Then multiply by 1/2. 51.84 * 0.50 = 25.92 cubic cm.

ANSWER:

59.4

EXPLANATION:

2.4 x 3.6 x 1/2 = 4.32 x 2 =  8.64

3.6 x 6 = 21.6

2.4 x 6 = 14.4 x 2 = 28.8

add it up and there ya go

Answer:

60??

Step-by-step explanation:

so the measure of a full circle is 360, so if its a half circle it is 180, and its divided into 3 sections( the porblem is if there not even sections this is wrong, i cant tell if they are or not)  so you do 180 divided by 3 and your answer is 60. if there are uneven sections all you have to do it take your protractor and line up the stright line with the bottom line then see what small number is the line pointing too. Sorry if this dosent make sense i can try to clarifi if you dont get it.

Answer:

12

Step-by-step explanation:

a=ab/2

Area=3 times 4/2= 6

but there are 2 traingles so 6 times 2= 12

Let that be x

[tex]\\ \rm\dashrightarrow 9\times \dfrac{6}{4}=x\times \dfrac{1}{4}[/tex]

[tex]\\ \rm\dashrightarrow 9(6)\times \dfrac{1}{4}=x\times \dfrac{1}{4}[/tex]

[tex]\\ \rm\dashrightarrow x=9(6)[/tex]

[tex]\\ \rm\dashrightarrow x=54[/tex]

WXYZ is opposite of ABCD. If I'm wrong, in my defense, I haven't done quadrilaterals in a while.

Answer:

B is the correct answer

Step-by-step explanation:

Check the picture below, on the left side.

since the triangle ABC is an isosceles with twin sides, if we drop a line bisecting the angle at the vertex A, we end up with a perpendicular line that cuts the "base" in two equal halves, so then

[tex]\textit{using the pythagorean theorem} \\\\ c^2=a^2+b^2\implies \sqrt{c^2-a^2}=b \qquad \begin{cases} c=\stackrel{hypotenuse}{50}\\ a=\stackrel{adjacent}{14}\\ b=opposite\\ \end{cases} \\\\\\ \sqrt{50^2 - 14^2}\implies \sqrt{2500 - 196}=b\implies \sqrt{2304}=b\implies 48=b[/tex]

as you can see in the picture in red, now let's find CD.

[tex]\stackrel{\textit{pythagorean theorem}}{\sqrt{52^2 - 48^2}=14}+CD\implies \sqrt{2704-2304}=14+CD \\\\\\ \sqrt{400}=14+CD \implies 20=14+CD\implies 6=CD[/tex]

Answer:

Step-by-step explanation:

CD= 6

Answer:

The second one

Step-by-step explanation:

Answer:

? would equal 25

Step-by-step explanation:

You plug the input into the rule. When x=4, y=21 because 4(4) +5 =21. The 4 in the parentheses is the input. So you would do the same when the input is 5. 4(5) +5= 25

Answer:

3/20 = MAD or 0.15 as a decimal

1/2= Mean or 0.5 as a decimal

Step-by-step explanation:

Answer:

Part A) If would probably be smart to use substitution because y is already solved for, so we can substitute the value of y as a function of x into the other equation.

y=7x-8

y=5x-2

7x-8=5x-2

   +8     +8

-----------------

7x=5x+6

-5x  -5x

----------------

2x=6

/2   /2

-----------

x=3

y=7x-8

y=21-8

y=13

Part B) The lines will intersect at point (3, 13)

Step-by-step explanation:

hope this helps

so sorry if this is wrong

did this for hw

Answer:

Step-by-step explanation:

part a:

substitution

7x - 8 = 5x - 2

2x - 8 = -2

2x = 6

x = 3

y = 7(3) - 8 = 21 - 8 = 13

y = 13

Part b.
