Well first we must see if they are proportional.

46.2/6 = 10.7.8/14
7.7 = 7.7

They are proportional. The rate of proportion is 7.7 ounces per cellphone. Hope this helps!

Answer:

<h2>They have a proportional relationship, with a constant of proportionality of 7.7</h2>

Step-by-step explanation:

<em>A proportional relationship refers to the equivalence between two reasons, or two fractions.</em>

So, in this case, we have the two reasons.

<h3>First reason: </h3>

\frac{46.2 \ ounces }{6 \ cellphones}

<h3>Second reason:</h3>

\frac{107.8 \ ounces}{14 \ cellphones}

Now, to find if these reasons are proportional we just have to equalize them and find if both fractions have the same result:

\frac{46.2 \ ounces }{6 \ cellphones}=\frac{107.8 \ ounces}{14 \ cellphones}\\7.7=7.7

<em>As you can see, both fractions have the same result, this means that those reasons have a proportional relationship, and the constant of proportionality is 7.7.</em>

Triangle WXY is isosceles. ∠YWX and ∠YXW are the base angles. YZ bisects ∠WYX. m∠XYZ = (15x)°. m∠YXZ = (2x + 5)°. What is the me
DiKsa [7]

Answer:

Option D is correct.

The measure of \angleWYX = 150^{\circ}

Step-by-step explanation:

\triangle WXY is isosceles  and \angle YWX and \angle YXW are base angles.

Isosceles Triangle:

A triangle with two equal sides, and two congruent base angles that means the angles are equal

By the definition, the base angles are equal i.e, m\angle YWX=m\angle YXW

Since, YZ bisects m\angle WYX

Angle Bisector theorem: An angle bisector is a line or ray that divides an angle into two equal angles

then, \angle WYX =2\angle XYZ or

Substitute the value of \angle XYZ=(15x)^{\circ} ;

\angle WYX =2(15x)^{\circ} = (30x)^{\circ}

The sum of measures of these three angles of  triangle WXY is equal to the 180 degree.

In triangle WXY we have;

\angle YXW+\angle WYX+\angle YWX=180^{\circ}

Substitute the value of m\angle YWX=m\angle YXW=(2x+5)^{\circ} and \angle WYX=(30x)^{\circ} in above formula:

2\angle YXW+30x=180^{\circ} or

2\cdot(2x+5)+30x=180^{\circ}

Simplify:

4x+10+30x=180^{\circ}

Combine like terms ;

34x+10^{\circ}=180^{\circ} or

34x=170^{\circ}

Simplify;

x= \frac{170}{34} =5^{\circ}

Substitute the value of x in  \angle WYX;

\angleWYX = (30x)^{\circ} = 30 \cdot 5 = 150^{\circ}

Therefore, the measure of \angleWYX = 150^{\circ}

Edgar accumulated $11,000 in credit card debt. If the interest rate is 30% per year and he does not make any payments for 3 year
Gennadij [26K]

Answer:

= 1.38778e-141 which makes interest a large amount 139 million and 108 hundred thousand and fourhundred and four.

Step-by-step explanation:

The equation is A= P 1+ r/n ^nt

So we input for A = (11000) x 1.30/11000 ^ 36 x 3

= 1.38778e-141 which makes interest a large amount 139 million and 108 hundred thousand and fourhundred and four.

The formula used in the compound interest calculator is A = P(1+r/n)(nt)

A = the future value of the investment

P = the principal investment amount

r = the interest rate (decimal)

n = the number of times that interest is compounded per period

t = the number of periods the money is invested for
