A. Constant of proportionality in this proportional relationship is; k=5

B. Equation to represent this proportional relationship is : c=t/k

Step-by-step explanation:

A.Given that : the amount she pays each month for international text messages is proportional to the number of international texts she sends, then

$3.20 k = 16  ---------where k is the constant of proportionality

k= 16/3.20 =5

k=5

B. Let c be the cost of sending the texts per month and t be the number of texts sent per month , so

c=t/k

c=t/5 ---------- is the proportionality relationship.

For t=16 , c= 16/5 =$3.20

Express the following ratio in lowest terms.<br> 105 knives to 120 spoons
kondor19780726 [428]

Answer:

the ratio in lowest terms is: 7 knives to 8 spoons = 7/8

Step-by-step explanation:

First express the ratio 105 knives to 120 spoons as the quotient:

\frac{105}{120}

next write each of the numbers in prime-factor form:

105 = 3 x 5 x 7

120 = 2 x 2 x 2 x 3 x 5

Now notice that when we express the quotient sing the factor form of the numbers, the factor 3, and 5 can be cancelled out because they appear in numerator an in denominator at the same time. therefore our quotient becomes:

\frac{105}{120} =\frac{3*5*7}{2*2*2*3*5} =\frac{7}{2*2*2} =\frac{7}{8}

Therefore the ratio in lowest terms is: 7 knives to 8 spoons

alexira [117]
We know that the diameter of the inner circle (d) and the side of a regular octagon (s) are tied by the formula:

d = (1 +√2) × s

The inverse formula is:

s = d / <span>(1 +√2)

Plugging in numbers:
s = 7 (1 + </span>√2)
   = 2.9 ft

Therefore the correct answer is A) <span>2.9 feet</span>

The following two-way table describes student's
guajiro [1.7K]

P ( work/ senior ) = 0.14

The attached table

required

P ( work/ senior )

This is calculated using:

P ( work/ senior ) = n ( work/ senior )/ n ( senior ).

n ( work/ senior ) = 5

n ( senior ) = 25 + 5 + = 35

So:

P ( work/ senior ) = 5/35

P ( work/ senior ) = 0.14

Add 25+5+5 (because that is all the numbers in the 'Seniors' row) and then take the 5 that is in the 'Work' column and put that over 25. (5/25 fraction as a percent is 14).
