Reapuesta: 8d = 80u

Tenemos que una decena equivale a 10 unidades.

Debemos multiplicar las 8 decenas por el valor de una sola decena.

$\: \: \: \Rightarrow\bf{8(10) = 80 \: unidades}$

8 decenas equivalen a 80 unidades.

She sold 54 of thin mints, which was 60 percent of the total number she sold. how many total boxes did she sell?

Mila [183]

Set up a proportion

54 60
— = —
x 100

(100)(54)= 60(x)

5400=60x

x= 5400/60

x=90

Answer:

Step-by-step explanation:

Please refer to the Image attached to this.

The Line passing through the rainbow represents the Airplane Trajectory.

a) Domain and Range :

Domain is the set of values of which a function is satisfied. Range is the set of all possible output values from a function. In this problem, referring to the image attached , we can see that the , we have some or other value of y for every x . That means that, it is defined for every real value in x. Hence the Domain will be Set of all real numbers . Where as the maximum value of y we have in this problem is 36. But y has no end towards negative side. Hence the possible outcomes are from negative infinity to 36. Hence range will be (-∞,36] , where 36 is included.

Domain = R

Range = (-∞,36]

b) x and y intercepts represents the distance of points where a graph cuts the both axes from the center. Please refer to the image attached. Here we can see that for our function $y=-x^2+36$

X intercepts are = ±6 as they cut x axis on two points ( -6,0) and (6,0)

Y intercept = 36 as graph cuts y axis at one point (0,36)

c) The linear function will the equation of line passing through (-5,11) and (4,20)

The slope of line will be

$m=\frac{20-11}{4-(-5)}$

m=1

Hence the function has a positive slope here , and hence we can say that it is a positive function.

The equation will be

$\frac{y-20}{x-4}=1$

y-20=x-4

$y=x+16$

now we are having two equations.

i) $y=-x^2+36$

ii) $y=x+16$

The solution of above two system of linear equation will be the points at which they intersect. Referring to the image attached we can see that they are intersecting at (-5,11) and (4,20) . Hence x=-5 & 4 are the solution to the system of equation we have now.

Question 3:

Please refer to the Image attached for the piece wise function

Here we have assumed two function with condition like given under

y=x+1 { x ≤ 3 }

y=4 {x > 3}

for values less than or equal to 3 , we have our function as y=x+1

let us graph this by joining two coordinates

x=0, y =1

x=1 , y= 2

x=3 , y=4

Hence we have two coordinates as (0,1) and (1,2)

we join them and limit it upto only (3,4)

because for values x>3 , the function will result us , y=4

which is a constant function , hence for every value of x . 3 , we will have 4 as output. Hence it will represent a straight line parallel to the x axis at a distance of 4 units from it.

A bank loaned out $17,500, part of it at the rate of 10% annual interest, and the rest at 14% annual interest. The total interes

Gennadij [26K]

Answer:

$7 000 was loaned at 10 % and

$10 500 was loaned at 14 %

Step-by-step explanation:

Let x = amount loaned at 10 %

Then 17 500 - x = amount loaned at 14 %

0.10x = interest on 10 % loan

0.14(17 500 - x) = interest on 14 % loan

2170.00 = total interest

$\begin{array}{rcl}0.10x + 0.14(17 500 - x) & = & 2170.00\\0.10x + 2450 - 0.14x & = & 2170.00\\2450 - 0.04x & = & 2170.00\\-0.04x & = & -280\\\\x & = & \dfrac{-280}{-0.04}\\\\x & = & \mathbf{7000}\\\\\end{array}$

$7000 was loaned at 10 % and

$10 500 was loaned at 14 %

Check:

\ $\begin{array}{rcl}0.10\times 7000 + 0.14(17 500 - 7000) & = & 2170\\700 + 0.14(10 500) & = & 2170\\700 + 1470 & = & 2170\\2170 & = & 2170\\\end{array}$

OK.
