Here is a flower made up of yellow hexagons, red trapezoids, and green triangles.
Law Incorporation [45]

Answer: Part a) You could build 5 copies of the flower pattern  

Part b) You would have 40 red trapezoids left over

Step-by-step explanation:

The complete question in the attached figure

Part a)

Let

x -----> the number of yellow hexagons

y ----> the number of red trapezoids

z ----> the number of green triangles

we know that

The flower pattern has the following ratios

\frac{x}{y}=\frac{6}{2} ----\frac{x}{y}=3 ---- \text {equation A}

\frac{x}{z}=\frac{6}{9} --\frac{x}{z}=\frac{2}{3} -- \text {equation B}

\frac{y}{z}=\frac{2}{9} ------ \text {equation C}

Find out how many copies of this flower pattern could you build if you had 30 yellow hexagons,50 red trapezoids, and 60 green triangles

1) For x=30

Divide 30 by 6 (remember that in one pattern there are 6 yellow hexagons)

30/6=5\ copies

Verify the quantity of y needed and the quantity of z needed

Find the value of y

\frac{30}{y}=3 ----y=30/3=10\\

10 < 50 ----> is ok

Find the value of z

\frac{30}{z}=\frac{2}{3} --- z=30*3/2=45

45<60 --->is ok

2) For y=50

Divide 50 by 2 (remember that in one pattern there are 2 red trapezoids)

50/2=25\ copies

Verify the quantity of x needed and the quantity of z needed

Find the value of x

\frac{x}{50}=3 ----x=50*3=150

150 > 30 ----> is not ok

3) For z=60

Divide 60 by 9 (remember that in one pattern there are 9 green triangles)

60/9=6.7 copies

Round down

6 copies -----> 6(9)=54 green triangles

Verify the quantity of x needed and the quantity of y needed

Find the value of x

\frac{x}{54}=\frac{2}{3} --- z=54*2/3=36

36> 30 --->is not ok

therefore

You could build 5 copies of the flower pattern

Part b)

we know that

x:y:z=6:2:9

If you build 5 copies

1) You would use 5*6=30 yellow hexagons and you would have 0 hexagons left over

2) You would use 5*2=10 red trapezoids and you would have (50-10=40) trapezoids left over

3) You would use 5*9=45 green triangles and you would have (60-45=15) triangles left over

therefore

You would have 40 red trapezoids left over

If a cyclist races at 30 miles per hour for 1/2 of the distance of a race, and 45 miles per hour for the final 1/2 of the distan
Natasha2012 [34]

Answer:

  36 mph

Step-by-step explanation:

The appropriate relations are ...

  time = distance/speed

  speed = distance/time

Suppose the race has a total length of 360 miles. Then half the race is 180 miles.

The cyclist's time on the first half is (180 mi)/(30 mi/h) = 6 h.

The cyclist's time on the second half is (180 mi)/(45 mi/h) = 4 h.

The total time is 10 h for the total distance of 360 mi, so the average speed is ...

  (360 mi)/(10 h) = 36 mi/h

_____

The length of the race doesn't matter. The above numbers make the math convenient. The average is computed from ...

  1/((1/2)/30 + (1/2)/45) = 2/(1/30 +1/45) = 2·30·45/(30+45) = 36

This is the <em>harmonic mean</em> of the numbers 30 and 45.

Eleven more than five times a number is equal to the difference between −38 and twice the number. Find the number.
Phantasy [73]

Answer:

x = -7

Step-by-step explanation:

Eleven more than five times a number is equal to the difference between −38 and twice the number.

let x represent the number.

11 + 5x = -38 - 2x

7x +11 = -38.............add 2x to both sides

7x = -49................... subtract 11 from both sides

x = -7........................divide both sides by 7

Higher Order Thinking On Friday,
oksian1 [2.3K]

Answer:

The Total number of peoples went to street fair including all three days is 785 peoples .

Step-by-step explanation:

Given as :

The number of people went to fair on Friday = F = 215 peoples

The number of people went to fair on Saturday = Sa = 163 more people than on Friday

So, The number of people went to fair on Saturday = The number of people went to fair on Friday + 163 peoples

∴, The number of people went to fair on Saturday = 215 + 163 = 378 peoples

And

The number of people went to fair on Sunday = Su = 192 peoples

So , The Total number of peoples went to fair = The number of people went to fair on Friday + The number of people went to fair on Saturday + The number of people went to fair on Sunday

So,  The Total number of peoples went to fair = 215 peoples + 378 peoples + 192 peoples

∴  The Total number of peoples went to fair = 785 peoples

Hence , The Total number of peoples went to street fair including all three days is 785 peoples . Answer
