Which statement best describes the methods used by Amanda and Billy to increase the time they spent exercising? A) Amanda's method is linear because the number of minutes increased by an equal number every week. B) Billy's method is linear because the number of minutes increased by an equal factor every week. C) Both Billy's and Amanda's methods are exponential because the number of minutes increased by an equal factor every week. D) Both Billy's and Amanda's methods are exponential because the number of minutes increased by an equal number every week.
A community college enrolled 96,000 students in 2007, and the enrollment has increased by 7% every year since then. Graph the exponential function, y, that gives the number of students enrolled in terms of t, where t is the number of years since 2007.-The graph of the function begins at y = 96,000. -The graph of the function does not have any asymptotes. -The graph of the function shows the exponential growth. -As t increases in the exponential function, the value of y approaches zero.

Can u help me in this algebra problem??

ok so
1 part almods
2 parts walnuts
3 part rasins
multiply them
almonds=12 per pound
walnuts=9 per pound
rasins=5 per pound

therefor
12 times 1+9 times 2+5 times 3=cost of ratio=45
45=a ratio with 1lb almond, 2lb walnuts, 3lb rasins

we need it to get down to 15
45/x=15
x=3

$45=1a+2w+3r
divide both sides by 3
$15=1/3a+2/3w+1r

we need to find total so add them
1/3+2/3+1=2

answer is 2lb

repair
so he has to pay the employees so that is a minus from his income
therefor
8600-22x
8600 is his income
-22x is the amount he has to pay his employees

they are paid 22 dollars an hour and that is taken from his income so
-22 times number of hour=amoont to pay employee
therefor x=number of hours worked per week

answer is 2

40. 2lb
41. no. 2 'hours worked per week'

Mr. Powell brought home $324.16 in net pay last week. His gross pay was $594.00. His net pay is what percent of his gross pay? 60%
55%
183%
18%

Answers

His net pay as a percent of his gross pay is 324.16/594.00 x 100 = 55%

Mr. Powell brought home $324.16 in net pay last week. His gross pay was $594.00. Then

$594 -- 100%,

$324.16 -- x%,

or mathematically it sounds as proportion:

$(\$594)/(\$324.16)=(100\%)/(x\%).$

Find x:

$x\%=(\$324.16\cdot 100\%)/(\$594)\approx 55\%$

Answer: correct choice is B

In a circle, the circumference and diameter vary directly. Which of the following equations would allow you to find the diameter of a circle with a circumference of 154 if you know that in a second circle the diameter is 14 when the circumference is 44?

Answers

Answer:

$d=(7)/(22)* 154=49$

Step-by-step explanation:

Let circumference be C and diameter be d.

In a circle, the circumference and diameter vary directly that is

C = kd

You know that in a second circle the diameter is 14 when the circumference is 44.

C = kd

44 = k x 14

$k=(44)/(14)=(22)/(7)$

Circumference of unknown diameter circle = 154

$154=(22)/(7)d\n\nd=(7)/(22)* 154 = 49$

d=kC
Plug in what we know and solve for k:
14=k(44)
k=14/44

so
d=(14/44)(154)
x=49

The temperature dropped by −2.5 Celsius degrees for 5 consecutive days. What was the total decrease in temperature over the 5-day period, expressed as a signed number?

Answers

If the temperature dropped by -2.5 for 5 days, then multiply -2.5 and 5 to get the total decrease.
(-2.5)(5) = -12.5
Over the 5-day period, the temperature dropped by -12.5 degrees Celsius.
