Uma professora de artes pediu aos alunos para montarem mosaicos unindo peças. Nesse mosaico, essas peças deveriam ficar sempre ligadas pelos vértices, não poderiam se sobrepor e não deveria sobrar espaço entre elas. Além disso, para fazer esse mosaico, essa professora solicitou que todos os alunos utilizassem octógonos regulares, como o que está apresentado abaixo.

M100839H6_1

Para compor esse mosaico, junto com esses octógonos, os alunos tinham à sua disposição as peças do quadro abaixo.

M100839H6_2

Quais dessas peças os alunos poderiam escolher para compor esse mosaico?

Step-by-step explanation:

Answer 2

Answer:

é a letra D (II, III e IV)

Step-by-step explanation:

se você reparar no ângulo interno da figura do octógono está mostrando 135º e a primeira figura que no caso não encaixa mostra 60º, fazendo essa soma daria um total de 195º, o que passa de 180º que é a metade de uma circunferência, então não daria certo, ficaria uma parte sobrando, não se encaixando no mosaico.

Tom buys a hat for $13.00 plus 11% sales taxes.
Lyn buys a hat for $21.00 plus 9% sales taxes.
a) How much do Tom and Lyn pay for the hats? Show your work.
b) Who spent more on taxes?

Answers

Answer:

a)

Tom

Tax = (11/100) × 13

Tax = $1.43

Tom paid 13 +1.43 = $14.43

Lyn

Tax = (9/100)× 21

Tax = $1.89

Lyn paid 21 + 1.89 = $22.89

b) Lyn paid more for taxes.

Sam's Saddles is having a sale on cowboy hats. The hats are being sold for
a 30% discount. The expression below can be used to determine the cost
of a hat on sale (h). h -0.3h Which expression could also be used to determine the cost of a hat on sale?
0.30h
0.70h
1.30h
1.70h

Answers

Answer: 0.70h

Step-by-step explanation:

The hat is being sold at a 30% discount. The expression that shows this will be:

Price = h - 0.3h

When the 0.3h is subtracted from h, we have:

= 0.7h

Another way to get to that expression:

Hat is being sold at 30% discount which means that 30% has been removed from the value leaving:

= 100% - 30%

= 70%

Price is now 70% * Normal price which is denoted as h.

= 70% * h = 0.7h

Rolando imported 138 boxes of mangoes.

There were 24 mangoes in each box.


He reserved 72 mangoes for his friends and sold the rest to 3

customers.

If each customer bought an equal number of mangoes, how

many mangoes did each customer buy?

Answers

Answer:

Each customer bought 45 boxes which is equivalent to mangoes 3240 in total.

Step-by-step explanation:

1. Subtract 3 boxes from the total of 138 imported boxes. ( 3 boxes are the 72 mangoes for his friends )

2. Divide 135 by 3 ( The amount of customers ) = 45 boxes per customer.

3. 45 x 24 ( The amount of mangoes in each box ) = 1080

4. 45 boxes/1080 mangoes per customer.

To recheck:

1080 x 3 ( The amount of customers again ) = 3240.

135 x 24 ( The amount of mangoes per box ) = 3240.

Tyler's brother works in a shoe store. Tyler's brother earns a commission. The store bought a pair of shoes for $32 and sold them for $78. What percentage was the markup?

Answers

Answer:

The markup was 143.75%.

Step-by-step explanation:

In order to find the markup, you have to find the difference between the price the store paid for the pair of shoes and the price they sold them for, then divide that by the price they paid for the shoes and the result has to be multiplied for 100:

((78-32)/32)*100=(46/32)*100=1.4375*100=143.75%

According to this, the answer is that the markup was 143.75%.

A cyclist rides his bike at a speed of 27 miles per hour what is the speed in miles per minute? How many miles will the cyclist travel in 2 minutes ? Do not round answer

Answers

0.45 miles per minute. in two minutes it would be 0.9 miles

Answer:

The cyclist can travel 0.9 miles in 2 minutes.

Step-by-step explanation:

1 hour = 60 minutes

Set up a conversion equation:

27 mi/1 hr × 1hr/60 mins

It is easier to see when writing it on paper, but the fractions are set up in a way to cancel the units out until the only units left are miles and minutes

After multiplying the numerators together and then multiplying the denominators together, you should reach the answer:

27 mi/60 mins

The cyclist can travel 27 miles in 60 minutes, but how many miles can he travel in 2 minutes?

Set up an equation:

Variable x = number of miles

27 mi/60 mins = x/2 mins

Cross multiply

27 × 2 = 60 × x

54 = 60x

Divide both sides by 60

0.9 = x

Daniel deposits $8,000 into a continuously compounding interest account. After 18 years there is $13,006.40 in the account. What was the interest rate?

Answers

Answer:

r = 2.7%

Step-by-step explanation:

Interest rate compounded continuously

r = ln(A/P) / t

Where,

r = interest rate

A = future value

P = principal

t = time

r = ln(A/P) / t

r = ln(13,006.40/8,000) / 18

= ln(1.6258) / 18

= 0.4860000023303 / 18

= 0.0270000001294

Approximately

r = 0.027

Convert value of r to percentage

r = 0.27 × 100

r = 2.7%

Which equation best represents c, the total amount Mr. Thomas should be charged
for driving m miles?

Answers

Answer:

c = 0.15m + 45

Step-by-step explanation:

Generally, we have the equation of a straight line as;

y = mx + b

where m is the slope and b is the y-intercept

To get the value of m, we can use the slope equation

m = (y2-y1)/(x2-x1)

Let us select two points to use from the table

we have;

(40,51) and (20,48)

So substituting these values;

m = (48-51)/(20-40) = 0.15

So we have the partially completed equation as;

y = 0.15x + b

To get the value of b, we use any of the points

Using the last, we have

51 = 0.15(40) + b

b = 45

So we have the complete equation as;

y = 0.15x + 45

using the terms in the question, we have;

c = 0.15m + 45

2x + 80 = 180

2x = 100

x = 50

Can I have Brainliest?

X is 50

The triangle in the picture is an isosceles triangle, that means two of the sides are equal. An isosceles triangle has two equal sides, therefore it also has two equal angles. That means that side QR is equal to QP, which also means that point P and point R have equal angles. We know that the angles in a triangle must always add up to 180°. We already know the information for angle R and angle P so we can add those together, this gets us 70°. We can now build an equation with the information we have: 2x + 10 + 70 = 180. Solve the equation and you’ll have your final product, x = 50.
