Answer 1

Answer:

Step-by-step explanation:

tan55=8.9/x

x=8.9/tan55

x=6.2cm

Answer 2

9514 1404 393

Answer:

  (a)  6.2 cm

Step-by-step explanation:

You don't need to know much about trig here. You only need to know that the other acute angle in the triangle is less than 55°, so the measure of side x will be less than 8.9. Only one answer choice qualifies:

  x ≈ 6.2

__

If you actually want to do the trig, as opposed to simply rejecting unreasonable choices, then you want to make use of the tangent relation.

  Tan = Opposite/Adjacent

  tan(55°) = 8.9/x

  x = (8.9 cm)/tan(55°) ≈ 6.23 cm

  x ≈ 6.2 cm

Trinidad Martinez sells office furniture. She is guaranteed a minimum salary of $2,500 per month plus commissions of 3.5%. Her total sales this month were $81,000 What is her total gross pay for the month?

Answers

Answer:

$5335

Step-by-step explanation:

Given data

Minimum salary= $2,500 per month

Commission=  3.5% of total sales

We are given that total sale = $81,000

Hence the expression for the gross pay

=2500+(3.5/100)*81000

=2500+0.035*81000

=2500+2835

=$5335

Hence the gross pay

=$5335

Answer:

Step-by-step explanation:

every time x goes up 1,  y goes up 4  

x = 3  minus x = 2  is a delta (a change of 1)

x = 4  minus x = 3  is a delta (a change of 1)

x = 5  minus x = 4  is a delta (a change of 1)

       the delta x is ALWAYS 1 for this table you can always substract x's to find the delta     delta is symbolized by Δ      Δx  for the delta x

y = 7  minus y = 3  is a delta (a change of 4)

y = 11  minus y = 7  is a delta (a change of 4)

y = 15  minus y = 11  is a delta (a change of 4)

    the delta y is ALWAYS 4 for this table you can always substract y's to find the delta     delta is symbolized by Δ     Δy  for the delta y

the slope m = Δy / Δx      m = 4 / 1     m = 4

     y = mx + b             when x = 0    then  y = b   (called the y intercept)

so how do we find the y intercept?    

look at the pattern in the TABLE  Δx  and Δy

   when x = 1    y = (3 - 4)  = -1

             x = 0    y =( -1 - 4)   = -5

so       y = 4x - 5     is a line equation for the data in this table

                                I believe there are other forms for linear equations

                               I chose the y-intercept form

use the point slope equation

       (y - y1)  =  m(x - x1)            where (x1, y1)  are the coordinates of a point on  

                                                the line

       when you know the slope of the line and a point on the line

       as before

       m = (y2 - y1)  / (x2 - x1)          from the table

           = (7 - 3) / (3 - 2)                 still equals

           = 4/1  =  4        

        pick a point on the line    say x= 4 and y = 11    (4, 11)

       (y - y1)  =  m(x - x1)    

        y - 11   =   4(x - 4)              point slope form

         solving point slope form  for  y

        y  - 11  =   4x - 16               add 11 to both sides    

           y  =  4x - 5                    back to the y-intercept form

C) $6,773.00
D) $6,776.84

Answers

Answer:

D, 6500 increased by 1.4% is 6591 plus another 1.4% which is 6683 and for the last year you add another 1.4% to get the final answer which is D 6,776.84

Answer:

P- 6500

R-1.4%

T- 3yrs

I-?

I first find simple interest,

I=P×R×T÷100

=273

then you add your answer to the price(6500)

273+6500=6773

​

Answers

Answer:

She has $125 in the register before selling any tickets.

Step-by-step explanation:

If the cost of each ticket is $80 then the equation would just be d=80n. However, by adding 125 without any coefficient, this would make our starting point 125 and not 0. Our starting point is how much money is in the register prior to selling anything.

Solve for x if 2(x - 2) = 26

A) x=25
B) x=8
C) x=15
D) c=30

Answers

C) is correct x=15
2x-4=26
2x=30
X=15

Answer:

The answer is C x=15

Step-by-step explanation:

Simplify both sides of the equation.

2(x−2)=26

(2)(x)+(2)(−2)=26(Distribute)

2x+−4=26

2x−4=26

Add 4 to both sides.

2x−4+4=26+4

2x=30

Divide both sides by 2.

2x /2  =  30/ 2
