Answer:

A. $2.15; $2.83

Step-by-step explanation:

2.83

c = 0.4. * 2.7 + 1.75

=> c = 2.83

4(2.7)+1.75

1.08+1.75=2.83

$2.83 is correct.

c=0.40(2.7)+1.75

c=1.08+1.75

c=2.83

Answer:

2.83 dollars

Step-by-step explanation:

Fixed charges made by the taxi company for a ride =  

Additional charge for each mile travelled =  

Hence equation for cost is given by

where m is thenumber of miles travelled.

To find out the charge for a 2.7 mile ride substitute m = 2.7

Total cost for 2.7 mile ride is 2.83 dollars

Answer:

To determine if a point E inside a square is closer to any of the vertices of the square we have to determine the length of the diagonals between the point E and the vertices of the square i.e. AE, BE, CE, DE

The diagonal can be determined by applying Pythagorean's theorem

Answer:

a. -21

b. -16

c. -11

d. -9

Step-by-step explanation:

if x is less than -2, then u have to use the equation 5(x)-1

if x is greater than or equal to -2, then you have to use the equation (x)-9

Answer:

Step-by-step explanation:

This is a ‘piece wise function’ meaning it has different functions depending on the value of the independent variable, x.

So for questions a and b where x<-2 you sub the x value into the top equation, 5x-1.

f(-4)=5(-4)-1=-20-1=-21

f(-3)=5(-3)-1=-15-1=-16

Since the second two x values are not less than -2, you sub the x values into the second equation x-9

f(-2)=-2-9=-11

f(0)=-0-9=-9

Answer:

Braxton's initial investment is equals to (=) Pam's initial investment.

The interest on Braxton's account is less than (< ) the interest on Pam's account.

Step-by-step explanation:

Given - Braxton has money in a savings account. The equation

            B = [tex]800(1 + 0.03)^{t}[/tex] can be used to calculate the amount of money    

           in dollars, B, Braxton has in his account after t years since opening

           the account.

           Pam also has money in a savings account. The equation

           P=[tex]800(1 + 0.04)^{t}[/tex]  can be used to calculate the  amount of money in

           dollars, P, Pam has in her account after t years since opening the

           account.

To find - Braxton's initial investment ..........Pam's initial investment.

             The interest on Braxton's account .....the interest on Pam's account.

Proof -

As given, Broxton equation is - [tex]800(1 + 0.03)^{t}[/tex]

               Pam equation is - [tex]800(1 + 0.04)^{t}[/tex]  

Now,

1.)

For initial investment , Put t = 0

⇒B = [tex]800(1 + 0.03)^{0} = 800(1) = 800[/tex]

  P =  [tex]800(1 + 0.04)^{0} = 800(1) = 800[/tex]

As for t = 0

Braxton's equation , B = Pam's equation,P

⇒Braxton's Initial investment = Pam's initial investment.

2.)

For the interest,

As we don not have time for which the interest has to be check.

So , let the time period = 5 years

Therefore,

B = [tex]800(1 + 0.03)^{5} = 800(1.03)^{5} = 800(1.1593) = 927.42[/tex]

P =  [tex]800(1 + 0.04)^{5} = 800(1.04)^{5} = 800(1.2166) = 973.32[/tex]

Now,

Interest on Braxton's account = 927.42 - 800 = 127.42 ≈ 127

Interest on Pam's account = 973.32 - 800 = 173.32 ≈ 173

∴ we get

The interest on Braxton's account is less than the interest on Pam's account.

Answer:

6x-4

Step-by-step explanation:

the perimeter is the distance around the shape, we get this by adding all the sides, call the missing side y and set up an equation for the perimeter

11x-7 = 4x+2 + x-5 + y

solve for y

11x-7 = 5x -3 + y

11x-4 = 5x + y

6x-4 = y

Step-by-step explanation:

step 1. 1-12/20 = 1.6

step 2. 1.6 = 160%.

Noticed how it forms a supplementary angle.

A supplmentary angle is basically two angles that added up to 180 degrees.

So we have:

64 + x = 180

Then we solve for "x", so "x" = 116.

Hope that makes sense :)

The largest 6-digit number is:

We need all digits different and the last one 0 or 5 because the number is the multiple of 5.

9876 are the first 4 digits and the last two 50 or 45, we'll chose 50 as 45 is smaller.

So the number is:

Answer:

The perimeter of JKL is 60 units.

Step-by-step explanation:

The two tangents of a circle formed by a vertex outside the circle will always be the same distance, this means that JA = JB = 13, LA = LC = 7, and KB = KC = 10. JL = JA + LA = 20, KL = LC + KC = 17, and JK = JB + KB = 23. So the perimeter of triangle JKL is 20 + 17 + 23 = 60 units.

Answer:

D

Step-by-step explanation:

I'm going to ponder a guess that the numbers shown, 0, 62, 1, 78, 2 ,etc. are part of a table. Having said that, the answers, when graphed, create a sort of parabola, meaning that the function itself is non-linear. This exterminates option A and B. Now its just a matter of seeing which way it goes, and since 78 is higher than 62, and 85 is higher than 78, it obviously increases, rather than decreases. This makes D our final answer.
