Step-by-step explanation:

Every side of the left triangle is 2x longer than the right triangle

And, the angle of the left triangle stay the same as the right triangle (since when we zoom out a triangle, the angle doesn't get bigger, only the sides do)

So yes, they have a proportional relationship.

Answer:

$241000

Step-by-step explanation:

Use the formula I = Prt

I is interest (what you need to find first), P is principal (200,000), r is rate (4.1%), and t is time (5)

First convert the rate of 4.1% to a decimal by moving the decimal two places left.

4.1%  = 0.041

Next plugin the numbers into the formula and multiply to find the interest.

I = 200000(0.041)(5)

I = 41,000

Finally you need to find the balance. To find the balance, add the interest to the principal.

B = 200000 + 41000

B = 241000

Answer:

y= -3/2x - 5

Step-by-step explanation:

Substitute (-6,4) into equation:

y = -3/2x + c

4 = -3/2 x -6 + c

4 = 9 + c

-9

-5 = c

Hope this helps!

Lets set up the equation:

p + w = 327  -- equation 1

p - w = 289 -- equation 2

equation 1 + equation 2

2p = 616

p = 308

Thus the plane flies at 308 mph without the wind.

Hope that helps!

Answer:

1600 boys, 2400 girls

Step-by-step explanation:

4000*4/10=400*4=1600

100-40=60

4000*6/10=400*6=2400

Answer:

no ( i think)

Step-by-step explanation:

so if i remember how to do this ratio and proportion.. ummm let me think of it as a fraction soo

3/8 = 15/45 ?

to get 15 (starting at 3) you have to multiply 5, so your guess is to multiply 8 to 5

it equals 40 not 45 so it is wrong and it is not equivalent

No.

[tex]15/3 = 5\\[/tex]

Use the 5 and multiply it by 3:8

[tex]5(3:8) = 15: 40[/tex]

It is equivalent to 15: 40.

[tex]15: 45 \neq 15: 40[/tex]

Answer:

Step-by-step explanation:

Given:

y = (-1/3)x +5

Compare the given equation with the general equation of the line:

y = mx+b,

where m=slope and b= y-intercept (where the line intersects the y-axis)

Our slope is m= -1/3, and our y-intercept is b=5

y-intercept is at 5 so we know one point on the line (0,5)

m= -1/3, negative slope means our line will be going down from left to right

m= rise /run = -1/3, so from point (0,5) we go down 1 (rise=-1) and right 3 (run=3) to get to a new point on the line (3, 4)

Draw a line trough the two found points (0,5) and (3,4)

Answer:

(5k-4)+2=46

(5k-4)+2-2=46-2

5k-4=44

5k-4+4=44+4

5k=48

5k/5=48/5

k=9.6

Answer:

38 muffins were sold by noon.

Answer:

38 muffins were sold

Step-by-step explanation:

percents can always be turned into fractions so 95% is actually just 0.95, you multiply that to 40 and you get 38, meaning 38 muffins were sold

Answer:

The ratio of the circumference to the diameter is equal to pi

Step-by-step explanation:

For circles

C = pi d   ( The circumference is equal to  the diameter times pi)

Divide each side by d

C / d = pi   The ratio of the circumference to the diameter is equal to pi

Answer:

The ratio of the circumference to the diameter is equal to pi

Answer:

37.5mph

Step-by-step explanation:

44m = 44/ 1000 km

44/1500 km : 11/1500h

60km : h

With a rhombus all 4 sides are the same length.

since one side is given as 25 we know the other 3 sides must also equal 25.

8z + 9 = 25

8z = 16

Z = 2

y-3 = 25

Y = 28

2x + 3 = 25

2x = 22

X = 11

answer: x = 11, y = 28 and z = 2

We know the figure is rhombus ; therefore all sides are equal !

Part one :-

To find value of y

→y - 3 = 25

→y = 25 + 3

→y = 28

Part two:-

To find value of x

→2x + 3 = 25

→2x = 25 - 3

→2x = 22

→x = 22/2

→x = (11 × 2)/2

→x = 11/1

→x = 11

Part three:-

To find value of z.

→8z + 9 = 25

→8z = 25 - 9

→8z = 16

→8z = 16/8

→z =(8 × 2)/8

→z = 2/1

→z = 2

Perimeter

Answer: 4.1

Step-by-step explanation:

Answer:

4 1/10

hope this helps have a good day :)

Answer:

Step-by-step explanation:

Find what you know.

Perimeter = 64cm

Length = width*3 + 8cm

Width = unknown (use w)

Perimeter of a rectangle formula is:

P = 2*L + 2*W or P = 2(L + W)

We know P and we have a formula for L

64cm = 2[(w*3 + 8cm) + w]

64cm = 2(3w + 8cm) + 2w

64cm = 6w + 16cm + 2w

Combine like terms:

64cm = 8w + 16cm

Subtract 16cm from both sides:

64cm - 16cm = 8w

48cm = 8w

Divide both sides by 8 to isolate the variable.

48cm/8 = w

6cm = w or swap them and w = 6cm

Now take the formula for perimeter again and plug in the value for width

64cm(P) = 2(L + 6cm(W))

64cm = 2L + 12cm

Subtract 12cm from both sides:

64cm - 12cm = 2L

52cm = 2L

Divide both sides by 2 to isolate the variable:

52cm/2 = L

26cm = L or swap them and L = 26cm

Rectangle is 26cm in length and 6cm in width.  There is no height variable in a 2D rectangle, but sometimes (rarely) width is referred to as height. If this is a 3D box, than the height is equal to the width, in which case the information given might be slightly misleading.

The perimeter = 2l + 2w

l = 3w+8

2l+2w = 64

2(3w+8)+2w = 64

6w+2w+16 = 64

8w + 16 = 64

8w = 48

w = 6 so l = 3(6)+8 = 26
