(1) Find values of x and y for which ABCD must be a parallelogram. The diagram is not to
scale.

Answer:

36 miles.......................

Step-by-step explanation:

let the ratio be x

now,

3x+5x+9x+13x=360°(sum of angle of quadrilateral is 360°)

30x=360°

x=360/30

x=12°

then,

3x=3×12=36°

5x=5×12=60°

9x=9×12=108°

13x=13×12=156°

so,the angles of quadrilateral are 36°,60°,108°& 156°

hope it helps.

Cost of a bike Raylin wants to buy = $85

Money Raylin already has = $22

Money she needs :

[tex] = \tt85 - 22[/tex]

[tex] = \tt\$63[/tex]

Thus, money Raylin still needs = $63

Money she gets from doing one chore = 2.50

Number of chores the needs to do :

[tex] = \tt \frac{63}{2.50} [/tex]

[tex]\color{plum} =\tt 25 \: chores[/tex]

Thus, Raylin needs to do 25 chores to be able to buy the bike.

Therefore, the correct option is (d) 25

x=12

In a similar the sides of the figure are in proportions. Therefore we can conclude that 16/12=x/9

Then just solve for the equation!

12x=144

x=12

Answer:

the ratio of wheat cereal to rice cereal is 1:6 and the value is 1/6 or 0.16666

Step-by-step explanation:

if 1 1/2 = 1/4 then ?=4/4

since we know the value of 1/4 we multiply 1 1/2x4=6 and 1/4x4=1 so the ratio is 1:6. The value of the ratio is the quotient, and the quotient of 1 and 6 is 1/6 or 0.16666

Answer:

x-intercept:   -5/2

y-intercept:   15/4

Step-by-step explanation:

to find x-intercept set y = 0

-6x + 4(0) = 15

-6x = 15

x = -15/6

x = -5/2

to find y-intercept set x = 0

-6(0) + 4y = 15

4y = 15

y = 15/4

Answer:

y-intercept is -2.5 and x-intercept is 3.75

Answer:47

Step-by-step explanation:

Make a hypothesis that the number is X, so X-14=20+13

X=20+13+14, eventually, you'll get that X=47

But I'm not sure if you mean 13 times more than 20, or just 13 more than 20

Answer:

c. (-1, -2)

Step-by-step explanation:

The solution is the point of intersection of the lines.

Read that point off the graph.

Start from the point where the x-axis and the y-axis intersect. Go left 1 unit. That is x = -1. Now go down 2 units. That is y = -2. The point that has x-coordinate -1 and y-coordinate -2 is the point (-1, -2). That is the solution.

The point is (-1, -2).

Answer: C. (-1, -2)

Answer:

so C but might be A

Step-by-step explanation:

Two quantities have a proportional relationship if they can be expressed in the general form y = kx, where k is the constant of proportionality. In other words, these quantities always maintain the same ratio. That is, when you divide any pair of the two values, you always get the same number k.

good luck, i hope this helps :)

Step-by-step explanation:

start by adding like terms which would gice us

3x+5x=8x so,

8x=32 divide by 8 on both sides so we leave x by itself giving us x=4

ok so as all of the angles in a triangle is 180 so

Answer:

F = 1

Step-by-step explanation:

3(f-1) + f =

3(1 - 1) + 1 =

3(0) + 1 =

0 + 1 =

1

Therefore F = 1 hope this helped! Please give me a 5 star rating????

Answer: f=1

Step-by-step explanation: 3(f−1)+f=1

3(f−1)+f=1

(3)(f)+(3)(−1)+f=1

3f+−3+f=1

(3f+f)+(−3)=1

4f+−3=1

4f−3=1

4f−3+3=1+3

4f /4 = 4 /4

f=1

Answer: 80%

Step-by-step explanation:

100% chance is normally the most so 100 is our whole. 100-20=80. That being the % makes 80% as the answer. Hope i helped!

Answer:

1/9

Step-by-step explanation:

if your question is about evaluting f^-2

then the answer is

f = 3

then

f^-2 = 3^-2 = 1/9

Answer:

3

Step-by-step explanation:

You meant f^-2(g) for f = 3 and g = 27.

(3^-2)(27)

= 1/9(27)

= 3

Answer:

[tex]A' = (0,0)[/tex]

[tex]B'= (9,18)[/tex]

[tex]C'= (21,12)[/tex]

Step-by-step explanation:

Given

[tex]A= (0,0)[/tex]

[tex]B= (3,6)[/tex]

[tex]C= (7,4)[/tex]

[tex]k = 3[/tex] -- dilation factor

Required

Determine the coordinates of the new triangle

This is calculated using:

[tex]New = Old * k[/tex]

So, we have:

[tex]A' = A *3[/tex]

[tex]A' = (0,0) *3[/tex]

[tex]A' = (0,0)[/tex]

[tex]B' = B * 3[/tex]

[tex]B'= (3,6)*3[/tex]

[tex]B'= (3*3,6*3)[/tex]

[tex]B'= (9,18)[/tex]

and

[tex]C' = C * 3[/tex]

[tex]C'= (7,4)*3[/tex]

[tex]C'= (7*3,4*3)[/tex]

[tex]C'= (21,12)[/tex]

Simple, Her Pentagon is not straight

Step-by-step explanation:

Carla's Pentagon is not straight. Her symmetry line is off scale. Simply fix the Line on the pentagon And it will be correct.

Hope this helps ^

We have that the correct Pentagon should have

Symmetry

This can be defined as an exact correspondence between different part of a system .

Therefore it can be said that Carla's Pentagon lacks Symmetry

Where a

Pentagon

is defined as a a shape with five sides and five angles

In this sense the is absolutely nothing with Carla's Pentagon
