Drag and drop the constant of proportionality into the box to match the table. If the table is not proportional, drag and drop "
olga_2 [115]

Answer: not proportional


Step-by-step explanation:

The constant is called the coefficient of proportionality if one variable is always the product of the other variable and a constant. And the variables are said to be directly proportional.

In the given table , let the variables are proportional then the constant of proportion(k)=\frac{y}{x}

\Rightarrow\ k=\frac{3}{2}=1.5

\Rightarrow\ k=\frac{7}{4}=1.45

⇒ k is not a constant of proportionality.

⇒ the variables x and y are not proportional.

The two triangles below are similar. What is the similarity ratio of ΔABC to ΔXYZ?
jek_recluse [69]

we know that

If the ΔABC and ΔXYZ are similar. then the  corresponding sides of the triangles are proportional

\frac{AB}{XY}= \frac{BC}{YZ}= \frac{AC}{XZ}

we have

AC=15\ units\\XZ=10\ units

Find the ratio

\frac{AC}{XZ}

substitute the values

\frac{15}{10}

Simplify Divide by 5 both numerator and denominator

\frac{15}{10}=\frac{3}{2}

therefore

<u>the answer is</u>

\frac{3}{2}

Evaluate cot 290º. Round your answer to the nearest hundredth. Explain each step
Paladinen [302]
Looking at the unit circle:
tanӨ = tan(Ө <span>± 180k)
If we add/subtract 180° from our angle, it simply ends up on the other side of the unit circle. Since tan</span>Ө is represented as slope, the values of the two are the same.

cotӨ is defined as the reciprocal of tanӨ (1/tanӨ)
If tanӨ = tan(Ө ± 180k), then we could also say that
1/tanӨ = 1/tan(Ө ± 180k) which then becomes cotӨ = cot(Ө ± 180k)

Let's apply this to cot(290°).
Subtract 180° to find that cot(290°) = cot(110°)

cot(110°) = -cot(70°) because the angle has been reflected across the y axis, making its slope opposite.

-cot(70°) = -1/tan(70°) because of that reciprocal property from earlier
tan(70°) ≈ 2.75
-1/tan(70°) ≈ -0.36 = cot(290°)

(of course, most calculators can handle tan(110°), but if you're using a trig chart it might not be on there. include whichever steps are necessary)

Jim's soccer team is making fruit baskets for a fundraiser. They have 88 peaches, 60 bananas, and 54 kiwis to use. If each baske
cluponka [151]

The greatest number of fruit baskets they can make is 2 with each one having 44 peaches, 30 bananas and 27 kiwis

<h3><u>Solution:</u></h3>

Jim’s fruit basket has 88 peaches, 60 bananas and 54 Kiwis to  use.

If each basket have same number of each type, we have to determine the greatest number of fruit baskets they can make  

We need to find greatest common factor of 88, 60 and 54

When we find all the factors of two or more numbers, and some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.

<em><u>Greatest common factor of 88, 60 and 54:</u></em>

The factors of 54 are: 1, 2, 3, 6, 9, 18, 27, 54

The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

The factors of 88 are: 1, 2, 4, 8, 11, 22, 44, 88

Then the greatest common factor is 2

On dividing the number of fruits by 2 we get

\begin{array}{l}{\text { Apples in each basket }=\frac{88}{2}=44} \\\\ {\text { Bananas in each basket }=\frac{60}{2}=30} \\\\ {\text { Kiwis in each basket }=\frac{54}{2}=27}\end{array}

Hence, there can be 2 basket with each one having 44 peaches, 30 bananas and 27 kiwis
