Let's find the required ratios first: to get to the relative percentages, we'll simply have to multiply by 100.

Since there are 16 girls, 10 boys and 9 adults, there are

16+10+9 = 35

people in total.

So, the ratio of girls is

\dfrac{16}{35} \approx 0.4571 = 45.71\%

The ratio of boys is

\dfrac{10}{35} \approx 0.2857 = 28.57\%

The ratio of adults is

\dfrac{9}{35} \approx 0.2571 = 25.71\%

A: 5x − 2y = 10
Nuetrik [128]

Answer:

D) Multiply A by -4 and B by 5

Step-by-step explanation:

5x-2y=10

4x+3y=7

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

-4(5x-2y)=-4(10)

5(4x+3y)=5(7)

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

-20x+8y=-40

20x+15y=35

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

23y=-5

y=-5/23

5x-2(-5/23)=10

5x+10/23=10

5x=10-10/23

5x=230/23-10/23

5x=220/23

x=(220/23)/5

x=(220/23)(1/5)

x=220/115

x=44/23

Instructions: Given the coordinates, Complete the translation (x,y)→(x+2,y−2) C(−5,−1) D(−4,3) E(−3,2) F(−2,0)
MAVERICK [17]

the translations is,

               C(-5,-1) → (-3,-3)

               D(-4,3) → (-2,1)

               E(-3,2) → (-1,0)

               F(-2,0) → (0,-2)

What is Translation ?

The changes in the value of the x and y  coordinates is known as translation.

Calculation:

The given points are C(-5,-1), E(-4,3), F(-3,2), F(-2,0).

according to the question (x,y)→(x+2,y-2)

 this means x coordinate changes by addition of 2

 And the y coordinate changes by subtraction of 2  

 Addition and Subtraction in the Coordinates,

             C(-5,-1) → (-5+2,-1-2) → (-3,-3)

             D(-4,3) → (-4+2,3-2) → (-2,1)

             E(-3,2) → (-3+2,2-2) → (-1,0)

             F(-2,0) → (-2+2,0-2) → (0,-2)

The inverse of the logarithmic function f(x) = log0. 5x is f−1(x) = 0. 5x. What values of a, b, and c complete the table for the
Elan Coil [88]

The value of a, b and c can be calculated using the inverse function.

The calculated the value of a= 2, b=1 and c= -2.

Given:

The function is  f(x)=\log_{0.5}x and its inverse is f^{-1}(x)=0.5^x .

<h3>What is an inverse function?</h3>
  • The inverse function of a function is defined if f is a function that undoes the operation of f.
  • The inverse of f exists if and only if f is bijective, and if it exists, is denoted by f^{-1}.

Substitute the value of x= -1 in a given inverse function and calculate the value of a.

f^{-1}(x)=0.5^x\\&#10;f^{-1}(-1)=0.5^{-1}\\&#10;f^{-1}(-1)=2

Substitute the value of x  is 0 in given inverse function.

f^{-1}(x)=0.5^x\\&#10;f^{-1}(0)=0.5^0\\&#10;f^{-1}(0)=1

Substitute the value of x  is 2 in given inverse function.

f^{-1}(x)=0.5^x\\f^{-1}(2)=0.5^2\\f^{-1}(2)=-2

Therefore, the value of a= 2, b=1 and c=-2.
