take Maria to earn enough money to buy the phone?

Answer:

Also doubles

Step-by-step explanation:

Hope this helps. Have a nice day you amazing bean child.

The constant of proportionality is 2.

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

We have [y] varies directly with [x] and y doubles then x.

The general equation of a straight line can also be used to represent proportional relationship when [c] = 0.

y = mx + c

y = mx + 0

y = mx

m = y/x

where [m] is constant of proportionality.

A/C to question -

y = 2x

Here, the constant of proportionality is 2.

Therefore, the constant of proportionality is 2.

Answer:  48

=================================================

Explanation:

The keyword "of" means multiply

150% converts to the decimal form 1.5; you move the decimal point two spots to the left to go from percent form to decimal form

Putting those two facts together lead to...

150% of 32 = 1.5*32 = 48

----------------

Another approach:

x% = x/100

150% = 150/100 = 1.5

150% of 32 = 1.5*32 = 48

The last step is identical as before, but the conversion of 150% is slightly different this time.

------------------

Yet another approach:

100% of anything is itself

So 100% of 32 is 32

The extra 50% means we take half of 32 to get 16. Then we add that onto the 32 to get 16+32 = 48

Answer:

4

Step-by-step explanation:

Rate of change is just slope, based on what I know.

Given 2 points : (x1, y1) and (x2, y2)... The slope would be [tex]\frac{y_{2}-y_{1} }{x_2-x_{1}}[/tex].

So for this problem we need to find the slope:

The rate of change is 4 based on my work.

Answer:

-2(x)>30

An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. 

x<-15

Step-by-step explanation:

-2(x)>30 means to divide -2 on both sides which is -15.

x>-15

Next you switch the inequality because you multiplied by a negative:

x<-15

Answer:

v = 21

Step-by-step explanation:

the sum of the interior angles of a triangle is 180 degrees

add all 3 angle measures and set equal to 180:  

4v + 2v + 54 = 180

6v = 126

v = 21

Answer:

  a) BE = 5; DE = 6; EF = 4

  b) ∠EFC ≅ ∠DA.F ≅ ∠BDE  or  b = e = f = i

Step-by-step explanation:

Each short segment is the same length as the marked one it is parallel to.

  E is the midpoint of BC, so BE = EC = 5.

  ADEF is a parallelogram, so DE = A.F = 6.

  D is the midpoint of AB, so AD = DB = 4. ADEF is a parallelogram, so ...

     EF = AD = 4

__

As we have noted, AB║EF and DE║A.F, so corresponding angles and alternate interior angles are congruent. b = e = f = i

Answer: The fourth set of sides

Step-by-step explanation:

For a set of side lengths to form a right triangle, they have to satisfy the Pythagorean theory [tex](a^{2} +b^{2} =c^{2} )[/tex]

First set of sides

a = 7.5    b = 18    c = 21.5

[tex]a^{2} +b^{2} =c^{2}\\7.5^{2} +18^{2} =21.5^{2} \\56.25 + 324 = 462.25\\380.25 \neq 462.25[/tex]

Second set of sides

a = 7.5   b = 19.5    c = 21.5

[tex]a^{2} +b^{2} =c^{2} \\7.5^{2} +19.5^{2} =21.5^{2} \\56.25 + 380.25 = 462.25\\436.5 \neq 462.25[/tex]

Third set of sides

a = 18     b = 19.25    c = 21.5

[tex]a^{2} +b^{2} =c^{2} \\18^{2} +19.5^{2} =21.5^{2} \\324 + 380.25 = 462.25\\704.25 \neq 462.25[/tex]

Fourth set of sides

a = 7.5     b = 18     c = 19.5

[tex]a^{2} +b^{2} =c^{2} \\7.5^{2} +18^{2} =19.5^{2} \\56.25 + 324 = 380.25\\380.25 = 380.25[/tex]

Answer:

What percentage would the wand need to have exactly a 50% chance of winning the wizard standoff?

a;50

Step-by-step explanation:

Answer:

50

Step-by-step explanation:

Since 140° is on the outside, the angle next to it would be 40°.

Also a triangle = 180°

40° + 90° = 130°

180° - 130° = 50°

Thus meaning x = 50°

Answer:

x = 50°

Step-by-step explanation:

- the angle at the top is shown as a right angle so it is 90°

-the 140° angle and the angle next to it are 180° together so let's name the other angle z

z+140=180

z=180-140=40°

- a triangle's angles in total have 180°

x+y+z= 180°

x+90°+40°=180°

x+130 =180

x= 180-130 = 50°

4/6 is the answer due to the way it is set up within the fraction

Answer:

Yes

Step-by-step explanation:

The two smaller squares have a sum of 169 which is the value of the larger square.

a^2 + b^2 = c^2

25 + 144 = 169

It can be done. Notice the figure below shows you how to arrange the squares to give the answer of a^2 + b^2 = c^2

Answer:

Yes, if we take the square roots of 25, 144 and 169 (5, 12, 13)

Not by using those measures as is (sides of a triangle with 25, 144 and 169).

Explanation:

A right triangle is a triangle with an angle of 90 degrees, and the side facing that angle of 90 degrees is called an hypotenuse.

The hypotenuse measurement squared is equal to the squared measurements of the other two sides:

c² = a² + b²

And those squares do verify the equation:

169 = 144 + 25

So, that's a rectangle (right) triangle, with sides measuring 5, 12 and 13.
