which of the following equation is true?

Step-by-step explanation:

I wrote the answer on the paper

Answer:

Step-by-step explanation:

Let M be the number of men donors and W the number of women donors.

We are told that M + W => 217  {"They noticed on Saturday that more than 217 people donated money."]

The total donations of no more than $3,702 consists of Men:  ($16)M and Women:  ($18)W

This makes the following equation:

18W + 16M <= 3702  ["no more than $3,702 was donated"]

The two equations are:

18W + 16M <= 3702, and

M + W => 217

=====

Extra credit:

To find the number of men and women donors, let's assume the equations are correct without the inequality signs.

Rearrange:

M + W => 217

M = 217-W

Now use this definition of M in the second equation:

18W + 16(217-W) = 3702

'

Solve for W:  W = 115:  There were 115 women donors at $18 each:  $207.

That means 217 - 115 or 102 men at $16 each:  &1632

Total donations of $3702

Answer:

$3,245

Step-by-step explanation:

Assuming that the $415 is paid yearly, Eddie has to pay a total of $3,245.

2,000 + (415 x 3)

2,000 + 1,245

2,000 + 1,245 = 3,245

Answer:

The total cost is $4.45

Step-by-step explanation:

I just added them

Step-by-step explanation:

let a= cost of sandwich=2.95dollars

b=cost of apple= 0.45dollars

c= cost of juice= 1.05 dollars

then t= total cost is calulated as:

t=a+b+c

t=2.95+0.45+1.05

t=4.45

P = sum of the sides

P = 1,8k - 5 + (3,5 + 6,1k) + (k + 1,5)

  = 1,8k + 6,1k + k - 5 + 3,5 + 1,5

  =        8,9k

Answer:

Step-by-step explanation:

If the diagonals in a rhombus are 8 and 6 then the perimeter is

a) 16

b) 18

c) 20

d) 22

the regular rhombus is formed by 4 right triangles, 1/2 of the diagonal is the cathetus.

8 : 2 = 4

6 : 2 = 3

find with Pythagoras the side of the rhombus

s = √(4² + 3²)

s = √(16 + 9)

s = √25

s = 5

now we find the perimeter by adding the 4 sides

5 + 5 + 5 + 5 = 20

Answer:

x = 90

Step-by-step explanation:

9x + 80 = 890 ( subtract 80 from both sides )

9x = 810 ( divide both sides by 9 )

x = 90

Step-by-step explanation:

For reason 3, look at how we got from step 2 to step 3.

In this case, we combined like terms or simplifies the left side.

So the reason for statement 3 is simplifying.

For statement 4, we look at how we got from step 3 to step 4.

Notice that we subtracted the same quantity, -12x, from both sides of the

equation and this is the subtraction property of equality.

For statement 5, we look at how we got from step 4 to step 5.

Here, we added the same quantity to both sides

and this is called the addition property of equality.

Finally, we use the division property of equality,

to get the final solution to the equation, x = 2/3.

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= 0.25

The inverse function of a function is defined if f is a function that undoes the operation  [tex]f^{-1}[/tex]

The inverse of f exists if and only if f is bijective, and if it exists, is denoted by [tex]f^{-1}[/tex] .

It is given that the function [tex]\rm F(x)=Log_{0.5}x[/tex] is and its inverse is

[tex]f^{-1}(x)=0.5^x[/tex] .

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

[tex]f^{-1}(x)=0.5^x[/tex]

[tex]f^{-1}(-1)=0.5^{-1}[/tex]

[tex]f^{-1}(-1)=2[/tex]

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

[tex]f^{-1}(x)=0.5^x[/tex]

[tex]f^{-1}(0)=0.5^0[/tex]

[tex]f^{-1}(0)=1[/tex]

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

[tex]f^{-1}(x)=0.5^x[/tex]

[tex]f^{-1}(2)=0.5^2[/tex]

[tex]f^{-1}(2)=0.25[/tex]

Thus 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= 0.25

Answer:

3657$

Step-by-step explanation:

You're supposed to enter numbers there I believe, in which case if 23 people payed 159 dollars for a ticket each that would be an equation that looks something like 159*23 which would bring you to the answer of 3657. maybe just put 0s in the first 2 boxes to fill it out.

The circle graph is used to show the preference of each customer

32 customers preferred bread

From the question, we have:

Bread = 47%

Total customers = 69

So, the number of customers that preferred bread is:

Bread = 47% * 69

Evaluate the product

Bread = 32.43

Approximate

Bread = 32

Hence, 32 customers preferred bread

Answer:

An right angle is an angle which is 90 degrees and obtuse angle which is greater than 90 degrees. There’s also an acute angle which is shorter than 90 degrees.

Step-by-step explanation:

What is a right angle and obtuse angle?

Answer: A right angle is defined as a 90-degree angle.

Step-by-step explanation:

A right angle in trigonometry is an angle of approximately 90 degrees or /2 radians, which corresponds to a quarter turn. Right angles are formed when the endpoint of a ray is on a line and the adjacent angles are equal.

Answer: An angle that is greater than 90 degrees but less than 180 degrees is called an obtuse angle.

Step-by-step explanation:

The smaller angle is the obtuse angle. It is greater than 90 degrees but less than 180 degrees.
