Answer:

B. 12n + 2(25) ≤ 100

Step-by-step explanation:

The inequality you are asked for is intended to express ...

shirt cost + pant cost (is less than or equal to) Sandy's budget

The cost of n shirts at $12 each will be 12n. The cost of 2 pants at $25 each is 2(25). Then the inequality is ...

12n + 2(25) ≤ 100 . . . . . matches choice B

Answer:

The ordered pairs of A and C are not functions

Step-by-step explanation:

To determine if the ordered pairs are a function you look at the x values to see if they repeat. You don't want one input(x values) to lead to two outputs(y values). This would mean that you are never sure which output you will get.

In the answer A the x value "2" repeats, in the answer C the x value "1" repeats thus not making them functions.

Raymond just got done jumping at super bounce trampoline center. the total cost of his session was $43.25\$43.25$43.25dollar sig

mina [271]

7 + 1.25m = 43.25
1.25m = 43.25 - 7
1.25m = 36.25
m = 36.25 / 1.25
m = 29....so Raymond was on the trampoline for 29 minutes

Which is an equation for the line that passes through (0,2) and (-2,0)

Arisa [49]

Y= x + 2

Plug in our x and Y values to check:

2 = 0 + 2
2=2 which is true.

0 = -2 + 2
0=0 which is also true, so it checks out.

I hope this Helps!

Which reason best describes why you can divide any number by 100 by moving the decimal point two places to the left?

11111nata11111 [884]

The last choice is the reason, but to add to this, you are taking a value and breaking it into groups of 100( which is 10 groups of 10). Each place value in our decimal system naturally is based on a system of tens! Dividing by 100, is 2 groups of tens (2 decimal moves).

Ted invests $8,310 in a savings account with a fixed annual interest rate of 2% compounded continuously. How long will it take f

Vsevolod [243]

Answer: It will take 8 years.

Step-by-step explanation:

Equation for interest compounded continuously:

$A=Pe^{rt}$ , A = accumulated amount , P=Principal value , r =rate of interest , t= time.

Given: P= $8,310 , r = 2% , A= $9,751.88

$9751.88=8310e^{0.02t}\\\\\Rightarrow\ \dfrac{9751.88}{8310}=e^{0.02t}\\\\\Rightarrow\ 1.17351143201=e^{0.02t}$

Taking natural log on both sides

$\ln (1.17351143201)=\ln (e^{0.02t})\\\\\Rightarrow\ 0.160000478068=0.02t\\\\\Rightarrow\ t=\dfrac{0.160000478068}{0.02}\\\\\Rightarrow\ t=8.0000239034\approx8$

Hence, it will take 8 years.
