Height of doll ÷ (7/10 of the height of doll)= size of the next doll

or
h÷(7/10)h = n

X= 12(.7)^x(exponent)
x is the doll you are on. For example if your looking for the height of the height of the doll after the 12 in. one then x=2 and so on

Determine if there is a proportional relationship between the two quantities
Shalnov [3]

Answer:

The table a not represent a proportional relationship between the two quantities

The table b represent a proportional relationship between the two quantities

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form k=\frac{y}{x} or y=kx

<u><em>Verify each table</em></u>

<em>Table a</em>

Let

A ----> the independent variable or input value

B ----> the dependent variable or output value

the value of k will be

k=\frac{B}{A}

For A=35, B=92 ---> k=\frac{92}{35}=2.63

For A=23, B=80 ---> k=\frac{80}{23}=3.48

the values of k are different

therefore

There is no proportional relationship between the two quantities

<em>Table b</em>

Let

C ----> the independent variable or input value

D ----> the dependent variable or output value

the value of k will be

k=\frac{D}{C}

For C=20, D=8 ---> k=\frac{8}{20}=0.40

For C=12.5, D=5 ---> k=\frac{5}{12.5}=0.40

the values of k are equal

therefore

There is a proportional relationship between the two quantities

The linear equation is equal to

D=0.40C

What is the expression to find the distance between the points A and T
navik [9.2K]

Answer:

<h2>9</h2>

Step-by-step explanation:

The <u>square root </u>of

d=(x2​−x1​)^2+(y2​−y1​)^2​

A=(2,5) coordinates 1

T=(5,5) coordinates 2

So we put (5-2)^2 plus (5-5)^2

(3)^2+(0)^2

9+0

9

How do the graphs of f (x) = x 2 and g (x)= 3/4 x 2? relate?
Agata [3.3K]

Answer:

g(x) is a horizontal stretch of f(x) by \frac{3}{4} units.

Step-by-step explanation:

The given functions are;

f(x)=x^2

and

g(x)=\frac{3}{4}x^2

The parent function is f(x)=x^2.

The  function g(x)=\frac{3}{4}x^2 is a horizontal stretch of  f(x)=x^2 by \frac{3}{4} units.

Maria is comparing the prices of two window cleaning companies. Company A charges $6 per window and an additional $12 as service
rewona [7]
Part A Answer: Company A: (Wx6)+12 Company B: (Wx5)+15 The varible used was W because windows start with a W i chose this as the variable because it is for the certain NUMBER of windows. Part B:Company A: 8x6=48+12=$70 for 8 windows and service charges. Company B:8x5=40+15=$55 for 8 windows and service charges. Company B would charge less for 8 windows. Part C:My work for Company A: 6x6=36+12=$48 for 6 windows and service charges My work for Company B: 6x5=30+15=$45 for 6 windows + service charges $48-$45=$3 Answer for Part C: $3 would be saved by using the services of Company B instead if Company A to clean 6 windows.

Jake plays baseball. He had 8 hits in his last 24 times at bat. Suppose he continues to bat at this rate. How many hits should
Zanzabum

Answer:

D. 10

Step-by-step explanation:

If he hits 8 swings every 24 swings, that gives you a ratio of 1 hit:3 swings. Using this ratio, you can take the 8 hits he already has, and add them on the 6 extra swings he did to get 30 swings. Using the ratio, he hits 2 more, and 8+2=10, so D.
