Help me with these questions, explaining it would be awesome!!

Answer:

Ben spent $9.32 on stamps total

Step-by-step explanation:

19x0.39= 7.41 because it says he bought 19 of these and they each cost $0.39 so you just multiply the two

8x0.24= 1.92 because of the same reason for the other it says he bought 8 of these and each costs $0.24 so you just multiply the two which gets you 1.92

next you add together the two totals of the stamps which is 7.41 and 1.92

7.41+1.92= 9.32

Step-by-step explanation:

1. -81/2 or -40.5

Both answers are correct forms I just didn't know if you wanted fraction or decimal form :)

2. Lots of answers for this one but ill give you mine: Mr. Candeleria probably rounded down his estimate number and in most cases like this you should round up.

Hope this helps :)

The solution is

a) The value of the equation is -40.5 or -81/2

b) Percentage error of Mr.Candelaria in estimating the tickets is 13.42 %

What is Percentage Error?

The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.

Percentage error is the difference between the measured value and the true value , as a percentage of the true value

Percentage Error = [ ( | Measured Value - True Value | ) / True Value ]x 100

Given data ,

a)

Let the equation be represented as A

Now , the value of A is

A = ( 3 4/5 )x - ( 2 1/2 )

On simplifying the equation , we get

A = ( 19/5 )x - ( 5/2 )

when x = -10 , substitute the value of x = -10 , we get

A = ( 19 × -2 ) - 5/2

A = -38 - 5/2

A = -81/2

A = -40.5

Therefore , the value of A is -40.5

B)

The measured value = 400 tickets

The true value = 462 tickets

Now , the percentage error in estimating the tickets by Mr. Candelaria is given by the formula ,

Percentage Error = [ ( | Measured Value - True Value | ) / True Value ]x 100

Substituting the values in the equation , we get

Percentage Error = [ | 400 - 462 | / 462 ] x 100

Percentage Error = [ | -62 | / 462 ] x 100

Percentage Error = 0.134199 x 100

Percentage Error = 13.419 %

Therefore , the percentage error is 13.42 %

Hence , the percentage error of Mr.Candelaria in estimating the tickets is 13.42 %

Third option

Step-by-step explanation:

All the other ones have a certain proportion

Answer:

$4956.23 approx

Step-by-step explanation:

Given data

P= $4860

R= 4%

T= 6 months = 0.5 years

Applying the compound interest formula we have

A=P(1+r)^t

Substitute

A=4860(1+0.04)^0.5

A= 4860(1.04)^0.5

A=4860*1.0198

A=4956.228

Hence the balance will be $4956.23 approx

Answer:

Option (1)

Step-by-step explanation:

Vertex form of the quadratic equation is given by,

y = (x - h)² + k

Where (h, k) is the vertex.

From the graph attached,

Vertex of the parabola is (0, 4).

Therefore, equation of the parabola will be,

y = (x - 0)² + 4

y = x² + 4

Function representing the parabola will be,

f(x) = x² + 4

For the zeros of the quadratic function we find the value of x where f(x) = 0.

x² + 4 = 0

x² = -4

x = ±√(-4)

Since, square root of a negative number is not defined, zeros of the function will be imaginary.

Therefore, both the zeros will be imaginary.

It's clear from the graph, there are no x intercepts of the function Or zeros are imaginary.

Option (1) will be the answer.

Answer:

z = 40°

y = 40°

x = 121°

Step-by-step explanation:

121 + 19 = 140

180 - 140 = 40

z = 40

y = 40

x = 121

40 + 19 = 59

180 - 59 = 121

Answer:it’s B trust me

Step-by-step explanation:

Statemen B is true about the given function.

A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.

A. The domain of f(x) is x > 0 is true for the function [tex]f(x) = (1/10)^x[/tex] because any positive real number can be raised to any real power, so the domain of this function is all real numbers greater than zero.

B. The statement "The graph contains (1)" is not clear. If it means whether the point (1, f(1)) lies on the graph, then we can find that [tex]f(1) = (1/10)^1 = 1/10[/tex], so the point (1, 1/10) lies on the graph. Therefore, the statement is true.

C. The function [tex]f(x) = (1/10)^x[/tex] is always decreasing because as x increases, [tex]f(x) = (1/10)^x[/tex] becomes smaller and smaller, approaching zero as x approaches infinity.

D. The range of f(x) is y < 1 because as x increases, [tex](1/10)^x[/tex] becomes smaller and smaller, approaching zero but never equaling one. So, the range of the function is all real numbers less than one, but not including one itself.

Answer:

nth term = 10 + (n - 1)-3

Step-by-step explanation:

a) 10, 7, 4, 1

First term,a = 10

Common difference,d = 7 - 10 = -3

nth term = a + (n - 1)d

nth term = 10 + (n - 1)-3

b 6, 4, 2,0

First term,a = 6

Common difference,d = 4 - 6 = -2

nth term = a + (n - 1)d

nth term = 6 + (n - 1)-2

c) 9,4 -1,-6

First term,a = 9

Common difference,d = 4 - 9 = -5

nth term = a + (n - 1)d

nth term = 9 + (n - 1)-5

d) 2.5, 2. 1.5, 1

First term,a = 2.5

Common difference,d = 2 - 2.5 = -0.5

nth term = a + (n - 1)d

nth term = 2.5 + (n - 1)-0.5

Answer:

3102x

Step-by-step explanation:

Answer:

(8, 2)

Step-by-step explanation:

Subtract the two D points.

(-12) - (-3) = -9

21 - 10 = 11

Then, use it to translate.

(17,-9)

(x - 9, y + 11)

= (8, 2)

The image of E(17,-9) under the translation will be (8,2)

The steps are as follow:

D(-3,10)

D'(-12,21)

D'-D = (-12+3,21-10)

X(-9,11)

E' = (17-9,-9+11)

E' = (8,2)

Therefore the image of E(17,-9) under the translation will be (8,2)
