The following figures show the first two steps of a proof of the pythagorean theorem. which of the following statements about this proof is false?

it's a multiplication!

not sure if you need the answer but just incase:

5(8+2)-4

= 5×(8+2)-4 (same as 5×8+5×2-4)

= 5×10-4

=50-4

=46

Answer:

100% it is  B. 1/2(172 - 58)

Step-by-step explanation:

The expression which gives the measure of ∠ACE in the diagram below is [tex]\frac{1}{2}[/tex] (172° - 58°). So option B is the correct one.

Secant angle theorem is a theorem which states that when two secants which intersects the circle at two different points are intersected at a point outside the circle, then the angle formed at the intersection is equal to the half of the measure of the intercepted arcs.

Given a circle with two secants, ABC and EDC, which touches the circle at different points.

They both intersects at point C.

The intercepted arcs are arc AE and arc BD.

Using the Secant Angle theorem, measure of angle ∠ACE is the half of the measure of arc AE and arc BD.

m ∠ACE = [tex]\frac{1}{2}[/tex] (AE - BD) = [tex]\frac{1}{2}[/tex] (172° - 58°)

Hence the required expression is 1/2 (172° - 58°).

The probability helps us to know the chances of an event occurring. The probability that the next card Craig selects will be a falcon

card is 3/17.

The probability helps us to know the chances of an event occurring.

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

Given that Craig gets 4 hummingbirds, 3 falcons, 1 woodpecker, 4 owls, 3

loons, and 2 eagles. Therefore, a total of 17 possible outcomes. Now, since the number of outcomes which are falcon is 3. Therefore, the probability of the next card being a falcon can be written as,

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

[tex]\rm Probability = \dfrac{\text{Number of falcon cards}}{\text{Total number of possible outcomes }} = \dfrac{3}{17}[/tex]

Hence, the probability that the next card Craig selects will be a falcon

card is 3/17.

Answer:

A = 3 ft, B = 7 ft, C = 4 ft, D = 5 ft, Surface Area = 96 ft^2

Step-by-step explanation:

Step 1:  Determine the sides

A → 3 ft

B → 7 ft

C → 4 ft

D → 5 ft

Step 2:  Determine the surface area

Area of the sides

[tex]A= 4\ ft * 7\ ft = 28\ ft^2[/tex]

[tex]A= 5\ ft * 7\ ft = 35\ ft^2[/tex]

[tex]A= 3\ ft * 7\ ft = 21\ ft^2[/tex]

Area of the top and bottom triangles

[tex]A= \frac{h\ *\ b}{2} = \frac{3\ ft\ *\ 4\ ft}{2} = \frac{12\ ft^2}{2} = 6\ ft^2 = 2(6\ ft^2) = 12\ ft^2[/tex]

Total Area

[tex]28\ ft^2 + 35\ ft^2 + 21\ ft^2 + 12\ ft^2[/tex]

[tex]96\ ft^2[/tex]

Answer:  A = 3 ft, B = 7 ft, C = 4 ft, D = 5 ft, Surface Area = 96 ft^2

Answer:

Surface Area = 96 ft^2

Step-by-step explanation:

A = 3 ft.

B = 7 ft.

C = 4 ft.

D = 5 ft.

Surface Area:

Triangle: Area = 1/2 * Base * Height

Top Triangle: Area = 1/2 * 4 * 3 = 1/2 * 12 = 6 ft^2

Bottom Triangle: Area = 6 ft^2

Rectangle: Area = Length * Width

Left Rectangle: Area = 7 * 4 = 28 ft^2

Mid Rectangle: Area = 7 * 5 = 35 ft^2

Right Rectangle: Area = 7 * 3 = 21 ft^2

Surface Area = TopTri + BotTri + LeftRect + MidRect + RightRect

Surface Area = 6 + 6 + 28 + 35 + 21 = 96 ft^2

Answer:

The scale drawing is 1 centimeter to 50 meters  ⇒ answer E

Step-By-Step Explanation:

* Lets explain how to solve the problem

- The height of the empire state building is about 1450 feet long and

 400 feet wide

- Andre wants to make a scale drawing of the front view of it on an

8 1/2 inches by 11 inches piece of paper

- We need to select one of these scales that we think is the most

appropriate for the scale drawing

A. 1 inch to 1 foot

B. 1 inch to 100 feet

C. 1 inch to 1 mile

D. 1 centimeter to 1 meter

E. 1 centimeter to 50 meters

F. 1 centimeter to 1 kilometer

- For scale A , B , and D the scaled image will not fit the page

- For scale C and F the drawing will be very small because 1 mile

is 5280 feet and 1 kilometer is 3280.84 feet

- E is most appropriate because 1 meter is 3.28084 feet, then the

height of the empire state is 442 m dividing by 50 m gives about

8.8 cm and the height of the paper is 11 inches which is about 28 cm

and the width of the empire state is about 122 m dividing by 50 m

gives about 2.5 cm and the width of the paper is 8 1/2 inches which

is about 22 cm then the drawing will be appropriate for drawing

∴ The scale drawing is 1 centimeter to 50 meters

Step-by-step explanation:

Step I: [Take only first 5 digits] A five digit number divisible by 5 can only end with '5'(0 is not allowed)

=> Middle digit is 5. Number is _ _ _ _ 5 _ _ _ _

Step II: All even digits should be even. because they'll be divided by an even number.

Step III: [Take only first 8 digits]An eight digit number with 6th digit as even number, last 2 digit can have only 4 combinations, . These are 96, 16, 72, 32. Number will be as follows:

(EDIT: Considering that it is divisible by 8 and 7th digit is odd)

_ _ _ _ 5 _ 1 6 _

_ _ _ _ 5 _ 9 6 _

_ _ _ _ 5 _ 7 2 _

_ _ _ _ 5 _ 3 2 _

Step IV: [Take only first 4 digits]A four digit number divisible by four ends only with 2 or 6. Keeping in mind that these number don't repeat only 4 Combinations are possible:

(EDIT: Using the fact that 3rd digit is odd and is divisible by 4)

_ _ _ 2 5 _ 1 6 _

_ _ _ 2 5 _ 9 6 _

_ _ _ 6 5 _ 7 2 _

_ _ _ 6 5 _ 3 2 _

Step V: [Take only first 6 digits]For a number to be divisible by 6; 6th number should be even and last three digit should add up to make a multiple of 3. Only 4 Combinations possible

_ _ _ 2 5 8 1 6 _

_ _ _ 2 5 8 9 6 _

_ _ _ 6 5 4 7 2 _

_ _ _ 6 5 4 3 2 _

Step VI: Now only one even number is remaining for occupying 2nd place in each of the above combination. For example in Ist case: 4 is the only remaining even number to be consumed. The combination will go as follows:

_ 4 _ 2 5 8 1 6 _

_ 4 _ 2 5 8 9 6 _

_ 8 _ 6 5 4 7 2 _

_ 8 _ 6 5 4 3 2 _

Step VII: Total 10 combinations remain:

1 4 9 2 5 8 1 6 _

9 4 1 2 5 8 9 6 _

3 8 1 6 5 4 7 2 _

1 8 3 6 5 4 3 2 _

3 8 1 6 5 4 7 2 _

1 8 3 6 5 4 3 6 _

1 8 9 6 5 4 7 2 _

9 8 1 6 5 4 3 2 _

1 8 9 6 5 4 7 2 _

9 8 1 6 5 4 3 2 _

Step VIII: Taking only first 7 digits of all of the above numbers. Only 3816547 is divisible by Seven

Complete number 381654729 is divisible by 9.

I am sure only 381654729 thus satisfies the answer.

Answer:

432 members

Step-by-step explanation:

300*1.2=360,360x1.2=432

300 represents the starting number, we multiply it by 1.2 because 1.2 means 20%, when we multiply, we get 360, that means that there are 260 members in december, so then we mutiply 360*1.2 in order to find out how many members there are in january, 360*1.2=432

Answer:

3570

Step-by-step explanation:

We use percentage formula here:

Beginning Amount * Percentage = Final Amount

Plug in the values

3200 * 15/100 = Final

480=  Final

Now we have 480 ppl growth from 97 to 07, so we have 3680 people

3680 * 3/100= Final

110.4= Final

110=Final

(Rounded)

Now that we decreased, we subtract 3680-110 and get the final population of 3570

We are given two metrics to work with: 10 years of time, and population change. The base is 3200 people at 1997. Ten years later, 3200 is increased to 3680 people, presumably due to living conditions improving. Another ten years later, the town's situation is stagnating. The population decreases somewhat, dropping down to 3569.6. This is because someone lost an arm and a leg, decreasing their person status to 60%.

Don't worry, we all over sleep sometimes. This is quiet simple. So you need to find x. 12 went from 12, to 4. So 12/_=4 The __ would be 3.
x on the other hand should be 3 as well. I could be wrong. But 12/3=4. So that'd be 12/3 Then it would be 4/3.
